 Good morning everyone. Welcome to this workshop. So, I will just get started with the talk. This is Professor Fartek as you have already been here one day. So, you have enough introduction. So, let me just talk about this National Mission on Education through ICT and then some of the activities that I want to give an overview of this mission itself, how you can participate in it, what are some of the projects that IIT Bombay is doing and then of course, there are some demonstrations are planned. So, these are the two things that I want to cover today. What is the National Mission on Education through ICT? How many of you have heard of this before coming here? All of you have heard of some of you most of you have heard of it. So, this mission is launched by M.H.R.D. The objective is to raise the levels of education. The outlay in this mission is rupees 4600 crore, 40 percent of which is reserved for content generation and then 60 percent for bandwidth. Most of it is to establish the infrastructure required to provide bandwidth. It is a very ambitious plan. It is likely to continue in the next plan period as well. Here, I told you that 40 percent of the money is reserved for content generation. So, let us see what the content generation topics are. They are classified into 18 line items. Do not have to remember all of this. I am going to give a link for this and then you can see all of this. The ones in blue are the ones that IIT Bombay is involved in. These are the remaining line items. This the workshop in which you will be participating in is covered under line item 12, talk to a teacher. So, that is what this TTT stands for, talk to a teacher. That is our mission. What is the minimum requirement for funding? Because this is meant to be done, this money is to be distributed for anybody who wants to participate in this, which means that you are all potential investigators in this mission. The mission invites you to write proposals. So, what are the requirements for funding? It should be related to education for research. Other funding sources are available. It should be inter institutional. Any material developed through this mission has to be delivered as open source. It should belong to one of the 18 line items mentioned earlier. No funding will be provided for infrastructure development. Funding is based on the deliverables. For example, you can say I am going to do so many courses. So, give me so much money or I am going to train so many faculty members, give me money. Number of that you are going to do 10 workshops, you are going to train 10,000 students, but you cannot say give me 100 computers, give me 2 computers. Because when you say give me computers, you are not stating the deliverable. So, the funding is based on deliverable only, not on infrastructure basis. The administration of the mission is as follows. There is a project approval board chaired by the secretary of M.H.R.D. There is a standing committee chaired by the mission director that recommends projects and there are of course many review committees. The mission director is Mr. N.K. Sinha joint secretary. His designation is joint secretary distance learning stroke training. So, we must be one of the few countries to have such a high level position for distance education. I am a member of this standing committee. How does one get funding in this? You submit a project and also a pilot for 6 months. The project is reviewed. Inputs from the standing committee members and other experts are taken. If the committee is convinced, then a pilot project is recommended. They will give small amount of your total project to run a pilot and to demonstrate. If you can demonstrate and show that you can indeed deliver it, the main project may be approved. So, either the pilot project is recommended as a standalone project or you are asked to participate in one of the already approved missions. They might say that why do not you join them? Why do not you join this project? They will give you money. In any case, we do not reject proposals. In the worst case, we ask P.I.S. to rewrite the proposal to submit an acceptable one. So, if you visit this site, there is a you will see a 10 minute spoken tutorial. Let me see if I can start that, see if I can go to the website. So, in this website, there is a 10 minute spoken tutorial. Hello friend, welcome to this brief talk to describe the national mission on education through ICT known as NME ICT. The objective of this talk is as follows to explain NME ICT so that you can write a proposal. We would love to receive your, this talk gives more details of format, where to submit your proposal, presentation details, etc. And NME ICT, NME ICT stands for national mission on education through ICT. It invites your proposals. So, to give a flavor of what this, what kind of projects are supported and what kind of projects are carried out, I want to give, I want to briefly explain some of the projects that are being done at IIT Bombay. And we would want you to participate in all of them, whatever projects that you are interested in. If you think that some of your colleagues may be interested in some or some of your students can contribute to these projects, then you can also ask them to get in touch with us. So, these are some of the projects that we have. The first one is 1000 teacher training program of Professor Fatheq that you already know about. There is actually another one that I wanted to write that I have missed out. This is NPTEL. NPTEL is something you are very familiar with. So, I have not, I am not going to talk about those, these two because you already know about them. So, I want to talk about IIT Bombay's courses open source that is our own courses, how we created them, how we made them available. I want to talk about this. I want to talk about some of the hardware projects that we are doing. I want to explain our open source software efforts and then I want to talk about spoken tutorials. You heard spoken tutorial. Why is it called spoken tutorial? I want to explain as we go along. First let me take up this open source course material. So, free courses and textbook from IIT Bombay. There are three items here. IIT Bombay's freely available courses, conversion into textbook and how you can participate. This institution CD Center for Distance Engineering Education program transmitted more than 100 courses in the last two years. For as one course meets 40 lectures of classroom instruction. It is like one subject or one paper. They were transmitted completely free through eduSAT and they were also transmitted through webcast. Anybody who had 100 Kbps link could receive them. We had actually optimized this transmission methodology so that our students can also receive because what happens is if you look at some of the transmissions from western sources, they always assume that people have bandwidth. They transmit at 512 Kbps or 1 Mbps, 2 Mbps and most of our public does not have access to. So, we had actually optimized for 100 Kbps. We also correspondingly chose the instruction methodologies to be suitable for 100 Kbps. For example, if you are transmitting only in 100 Kbps and you write on the blackboard, some of the lines may not be visible. So, we had to modify our instruction methodologies to do that. We are also hoping to make this available through DVDs for a low cost and we are also hoping to set up a data center from where you can stream all these courses. So, we have about 100 Kbps from various departments. Many of them are in the area of computer science and electrical engineering, electrical, electronics, telecommunication engineering. We have only one department called electrical engineering. It covers all of these. Tripoli, telecommunication, instrumentation, microelectronics, all of them come under electrical engineering. So, electrical engineering and computer science probably have half of these courses. So, this is the project proposal that I have made. You know, this is an area which is open at this point. It is a lot of work needs to be done. So, I would want your participation in this. So, this project aims to create textbooks starting from our video courses. The reason why we start with video courses is if I transcribe the video course, I already have 40 lecture worth of content and it is already delivered at IIT Bombay. That means students have gone through them. They have corrected mistakes and so on and so forth and it also corresponds to a particular syllabus. In view of that, we said that we will and it is available as open source. So, we first transcribe it and put it in a wiki. By wiki, I mean a technology not necessarily wiki itself. So, then once I do that from wiki, I can give links to the video clips. I can say that when somebody is reading through the wiki, I can say that listen to what an IIT Bombay professor says about it. So, they click it and it should take them to the video clip. By that I can also say that you want to listen to what an MIT professor says. Give a link to this and this will take the person to some other internet resource. Of course, I can put a link to slides, return sheets. As I mentioned earlier, we do not use blackboard. We use this document projection camera and people write on this and we scan and put them. So, each page is like a slide. So, we have either slides or handwritten scanned material available. Then what happens is this wiki grows through collaboration. This starts from IIT Bombay's video course and hence some material may be missing. For example, I may be teaching a control course and our students may have already undergone a lecture on Laplace Transforms. So, I do not cover Laplace Transforms. Whereas in some university, they might say Laplace Transform is to be taught in this course. So, obviously that topic will be missing. So, then people can contribute to this wiki. So, we have this wiki moderator who will ask people to contribute to this. So, experts from various works of life can write a chapter, can write a paragraph and so on contribute to this. So, in this manner the wiki is going to grow. So, very soon because of lot of things will be missing, people will go on adding, it will grow. Then it will become too big for any course for anybody in a college. It may even become twice as large as what is what can be done in a typical 40 hour course. So, what we do is we define something called syllabus. And of course, university exams are based on syllabus. Syllabus is extremely important and if you can use a book authoring tool to apply this syllabus on to wiki extract only the relevant portion and create a textbook. Obviously, this will depend on what is meant by syllabus. So, actually it is not a straightforward topic, but then some of the ideas are that syllabus can be defined in terms of prerequisites, index terms, keywords and then also things like how much of time has to be spent on this topic. Correspondingly you may say that only so much material is available to be taken or you might say that you may also define in terms of negatives. For example, you might say that it is for example, multidimensional calculus, but not Sobelov's theorem. So, you would leave out those things. So, syllabus you know if you can define this using the book authoring tool apply this syllabus on to wiki extract the relevant portion and create it put it in the textbook. So, what will happen is some manual intervention is required in this transcription and also in this textbook creation. Some material will not be added, some extra material will be there you may have to remove them and so on. But I believe that even if it is even if 70 80 percent of the thing can be created in an automated fashion then through manual intervention you can actually fix them. So, this is the textbook project that we are working on and so automatic transcription use of latex, math ML, data mining, Python XML these are some of the related areas for this and we need participation. Next I want to talk about open source hardware. By the way I am saying all this just to give a flavor of what kind of projects that we are doing. I have already talked about our transmission of IIT Bombay courses. We already have 100 courses. We are going to make them available on a server and so on. So, this is the textbook creation out of that. Now I am going to talk about open source hardware. First I want to talk about so there are three things I want to talk about a single board heater system and then virtual labs and then a low cost PC. These are the things I want to talk to you about. So, this is a single board heater system. I have a sample of this single board heater system. So, what is this? By controlling the temperature of a plant. So, it is actually so can I project this as we focused. So, underneath this plate is a small blade. I do not know whether you can see this. See this is where it is actually a very small blade whose temperature we try to control. The temperature is the blade is something like 1 centimeter by 4 centimeter. So, small blade control of its temperature is the objective of this unit. So, that blade is the plant. We want to control its temperature and we want to study all the issues related to that. So, the objective is to create a device for this purpose. So, that this can be used in a lab that studies control experiments. You will see that as I explained you will see that it can be used for several other things as well. So, this is heated by a nichrome coil and the you can see the wire from here. So, heating is done through that you can change the current that goes through it by pulse with modulation. This device can be cooled by a fan and the heart of this intelligence here is at mega 16 microcontroller that is behind this below this display. You can see a serial interface. You see that you can see that there is a serial interface there is a USB interface and of course, we have used what else do we need. We use the standard power supply. We use the standard power supply. So, that it can be bought off the shelf. The bill of materials for this is of the order of 1500 rupees. So, it has a plant, it has a microcontroller, sensors, actuators. In this case there are two actuators. The fan speed is one, the heater current is the second one. It is done through pulse with modulation through this at mega 16 microcontroller. It is used in process control, computer control, instrumentation, microcontroller, embedded systems, real time systems. It is available for rupees 2400. This company called Nex Robotics actually makes it available. So, you can just pay there and get it or design is also available as open source with bill of materials mentioned. So, if you have access to Lamington road or similar kind of resource, you can actually get them. I was thinking when I wrote this that it costs about 1000 rupees. It actually costs 1500 rupees bill of materials. The power supply is of the order of 3400 rupees and this AD 590 temperature sensor is little expensive. So, it comes to about 1500 rupees. This is useful in virtual labs. So, virtual labs is one of the projects supported by this mission. Its main aim is to create experimental resource at a few places and make them available for students all over the country. So, typically it is used for expensive equipment. Then one can ask why are we doing this for such an inexpensive one. It is so cheap. Everybody can buy. Why do we have to make it available through virtual lab? There are many reasons. The first one is if just because something is free, people are not going to use them. There is a learning curve. You need to understand how to use it. You need to set up a laboratory. You need to understand the instructions and so on. So, here what we plan to do is what we have already done is it is on the virtual lab. That means you go to a browser and then you go to type this URL and you will have gone to this and then it will say do this experiment. You can do the experiment and then you can see the results on the screen. Then you can download the results, save it and we also give the Sylab files. How many of you know about MATLAB? How many of you know about Sylab? Sylab is open source equivalent of MATLAB and I have some thing to say about this little later. So, we make available Sylab files also. So, you can actually analyze the data. So, if you are convinced of its utility, if you think that it is useful to you, so that can be that decision can be made without the infrastructure of getting some finding out how to use it, because all that take time. Here you find out then you say I want to use it, then I do not mind investing some more time. Then give a demonstration to your colleagues, to your head of the department, to students, whatever then you can take it forward. So, it is for that purpose, this virtual lab has a good role to play even for inexpensive equipment such as this. So, we have done large number of experiments using this device. So, we have created, we have written the document for every one of those, most of those. The instruction manual is more than 200 pages, run projects through students at IIT Bombay and distribute to, distribute this to colleges. And we have distributed, I wrote 20, we have distributed more than 50 as of now. And we want to encourage development of similar devices for other courses also. We are in fact going to conduct a workshop in the month of May, little later in this month. And then if you think that somebody would be interested in attending this from your college, they will be most welcome. The next thing that I want to talk about is real-time DAC, data acquisition devices, microcontrollers, DSP devices and so on through open source software. How many of you use Linux? Very good. So, there is a package called Comedie. How many of you know about Comedie? So, Comedie is an acronym for control and measurement device interface. It has interfaces for more than 100 A2D cards. So, which is, which means that the problem with, you know, using open source software is for data acquisition and things like that is, how do you, who, who do we have the device drivers? So, that is why this project is very important. So, we are thinking of setting up a rack, get all these cards, put them and then set up this interface, give standard inputs, give GUI support through RTAI, RTAI is another project that interacts with Sylab. So, the way it happens is you have Comedie sitting in the back end and that connects to the device and then after Comedie, you have RTAI and then Sylab as the front end. So, we can actually get the information from there and make this available to the remote people. That is the idea. Web enable this so that students can access them remotely. Repeat this for popular microcontrollers also. For example, I was talking about Atmel family and various other microcontrollers also, PIC microcontroller and so on, ARM microcontroller and set up all educational support through the web. So, this is one of the projects that we are working on. We actually want partners in all of this. If some of you can demonstrate that you have the capability that you have expertise in your institution that you want to join, so it will be very good. Another one I want to talk about is about building a low cost PC. Why is this important? Very soon bandwidth is going to be available because we are saying that 60 percent of the mission money of 4600 crore is to be used for establishing the bandwidth. As a matter of fact BSNL has been given this job and BSNL has given 95 percent discount for because of the large volume of the order which means that at 5 percent of the cost the bandwidth is going to be available and bandwidth will be available, content will be available. What about connectivity? What about giving PCs to students? So, here we are actually talking about a low cost access device. So, for example, we are talking about a motherboard which can have a low speed processor, let us say of the order of 512 megahertz, 1 GB RAM or even half a GB will be sufficient. So, we believe that this motherboard can be at the cost of about $10. The display device is a 7 inch device. We are talking about a small unit. The students can carry them with them to home and so on. This will be accessible even to poor students and also to school students and the other expenses keyboard, mouse, etcetera. The cost is $5, Linux wise or Google's operating system. So, we are thinking about a total cost of $25 to $30 for 10,000 pieces. So, the question is, is anyone here interested in building it? Do you think that you have a team at your institution that can participate in this? MHRD is very keen to get this done at various places in the country. So, that finally, you see the market for this is of the order of a million pieces. Million is nothing in India. Next, I want to talk about open source software. I am giving you a flavor of some of the projects done at IIT Bombay. So, that you can participate in this and you can also get ideas to write your own project proposals. Open source software at IIT Bombay we have a very big activity. So, this is actually one of the probably very important slides one of the most important slides in my talk. The commercial software is expensive unfortunately or fortunately our students think that it is free. In fact, I was using this, I was teaching this course called embedded systems. It is a CS 682. It is a computer science course it is taught by professor Kavya Ria and Krithiram Amritham and then I taught the controls part of the course and I taught using SILAP. Then I asked the students how many people in the class had used SILAP? There were 25 students and only one of them raised his hand. So, I scolded him why did he use SILAP? Looks like everybody uses MATLAB you are using SILAP. So, he said that he was working for an embedded systems company in the Pune region and that company was into niche products like all other embedded systems companies into creating microcontrollers and embedded systems for devices such as fans may be computers microphone mobile phones washing machines whatever you name it and this company his boss told him that MATLAB was too expensive and they could not afford it. So, can you tell me how much what was the? So, his boss told him a copy of MATLAB for their configuration would cost X amount. Can you tell me how much that student said? What is the cost of MATLAB to a company? Take a guess. Use of unauthorized software by commercial establishments results in disasters companies may even have to close down jail sentence etcetera because of this most of our small and medium scale enterprises in India do not use any software. Commercial software is expensive they are not aware of open source software because we do not train our students on open source software. It puts our companies at a great disadvantage many of our companies are in the small and medium size and so I conclude this slide by saying that there is no alternative to open source software. So, we are looking at Python Blender Sylab latex for this as part of open source effort. So, Python project is led by professor Prabhu Ramachandran of IIT Bombay. So, the website is fasi.in f o double s double e dot i n you want to take this down write this down led by professor Prabhu Ramachandran of IIT Bombay. Blender is useful for 3D animation professor Sridhar Iyer of IIT Bombay our computer science department is doing this. The web address is asker dot IITB dot AC dot IN creating animation supported content for educational material. Sylab is a good substitute for MATLAB and so you can look at Sylab dot org this is the original website our effort is in Sylab dot IN Sylab dot IN IN for India and so your participation is welcome. One project idea you take a any standard text book into and then so here I have written Sylab Python, but you can talk about any open source software and any text book any standard text book. Choose any text book get coded all numerical examples and some problems using Sylab Python or any other open source any other suitable software get the correctness certified by the subject expert get a hundred year partner with IIT. So, this is I was giving this talk to talk at Symbiosis in Pune and there a computer science professor came and said that he wanted to do one project on UML using the open source equivalent of UML take all the examples and code it. So, this is one and so this can be done through your projects or probably your students you might have some bright students and they may be looking for projects. So, let them do that Sylab MATLAB Python whatever that is not MATLAB Sylab Python or that UML software that I talked about and so on. Problems with open source software is that there are no good documents people will say where is the text book who will tell me how to use it and there is nobody spoken tutorials is one solution. What is that I will just give a demo of what I mean by a spoken tutorial. So, what I will do is let me open screen capturing software called I show you. So, can you see this line here this vertical line can you also see this horizontal line actually it defines a rectangle whatever is going to come in that is going to be captured. So, what I will do is I will do a demo using Sylab 5.2. Let me give a demonstration to the visitors for this workshop let me define a matrix A let it be a 3 by 3 matrix I have defined this matrix. Let me calculate the Eigen values of this matrix using the spectrum command let me define a vector x equals 1 through 10 and let me plot x. So, I have done the plot of course going back to the matrix let me find the inverse of this matrix I have computed. So, let me come to the let me conclude this demo. So, I have created this movie now see this let me give a demonstration to the visitors for this workshop let me define a matrix A let it be a 3 by 3 matrix I have defined this matrix. Let me calculate the Eigen values of this matrix using the spectrum command let me define a vector x equals 1 through 10 and let me define a matrix A let me plot x. So, I have done the plot of course going back to the matrix let me find the inverse of this matrix I have computed. So, let me come to the let me conclude this. So, how easy was it to create. So, I was doing something I was describing that activity and this technology is known as screen cast. It is a faithful reproducer it is like the person who explained who narrated Maharashtra war this Mahabharata war to Dhritarashtra a blind person who actually saw the war because he told everything. So, you can say this screen cast mechanism is that captures everything that happens on the screen it is a slave. I could have given the running commentary in any language I could have explained that in Hindi could have explained this in Marathi. So, let me just go here and then show you some of the things that we have this is the same website we went to just to give a power of this this spoken tutorial. So, I am this software camp studio is a open source software available on windows. So, you already possibly had this Bhojpuri. So, let me step process learning is more effective when animation and narrations are presented simultaneously and activity convert AVI files to flash files and many other uses the uses of this little known software are limitless camps. So, that was that let me show you Marathi is there anyone here any visitor knows Marathi anybody who has come from outside let us play Marathi. So, we have of course for example, we have someone who has come from outside Marathi. So, let take just one second you can see the power of this simple tool. Now, do you agree that if we make our slides and recorded videos available to teachers and if there are some enthusiastic teachers across the country then what I mentioned yesterday that in local languages they could interact with some students and they could create a spoken tutorial in their local language on any aspect of the programming course or for that matter any other course. So, we are going to heavily use this that is the proposal to extend the open source contents that we will be putting in the website. Then I want to show this we also have something called dubbing here if you click this by the way these are all in spoken dash tutorial.varj the same website in which that NME ICT talk is there. So, here dubbing on Windows voice using Windows movie maker. So, here I will show Hindi. So, it says how to, next I will go to this is on latex. So, we have study plans you can string together these spoken tutorials each tutorial is of 10 minutes duration. The idea is that you understand one topic the student can download the software and try them in parallel that is why the tutorial word spoken tutorial our target is to popularize any open source all open source software packages. So, let us take letter writing. So, letter writing study plan has two spoken tutorial compiling and letter writing. In letter writing we have four languages. So, let me click this not sure whether you can see the text these are little small, but I just want to demonstrate. Let us use letter writing. So, let us use letter writing. So, let us click this not sure whether you can see the text. So, let us click this not sure whether you can see the text. So, let me come back to this may finish my presentation. So, spoken tutorial refers to explaining a computer based activity along with a live demonstration of it in parallel with a running commentary which can be in any language to create this one needs a PC headphone with audio input which cost only about 100 rupees. The recording can be played back on a PC as a movie only a 10 rupee headphone is required. This can be a mass movement how to dub it we saw that we actually how did I produce all the dubbed ones in camp studio we ran a competition to dub the English into other languages. It turned out that the dubbed ones in Marathi and Hindi were actually better than English original. So, the dubbing one can actually be better. The important thing in this is so many people from IIT Bombay participated in it students children of support staff housewives. So, on anybody you know even retired people. So, we had all these languages I had links to all of this, but I have already demonstrated. What are the benefits the small file size. So, only about 1 MB per minute in fact less than 1 MB per minute in once CD you can pack more than 11 hours of spoken in 10 minutes in 10 rupee CD even a small bandwidth will do for streaming we are talking about you know making these available through mobile phones. Do you know the average time spent by a Mumbai Kerr in travelling every day if only that person can listen to one of the spoken tutorials. They want to learn about Python, they want to learn about Java, they want to learn about C programming, they want to learn about simulation software packages like Spice, Ascend. There are various open source tools available software. So, here our focus is on software spoken tutorial that the word tutorial says that this fellow can actually try that in parallel. So, the focus is coming through software and through software we can explain subject matter Ascend chemical engineering simulation, Spice electronic simulation. So, I have been you know I have been saying that it is cheaper than a text book because in one CD you can pack 11 hours of spoken tutorial and this a PC system with a headphone and so on will be cheaper to create than a classroom. I am not saying that replace them, I am saying that these are inexpensive you can add them. Running commentary can be dubbed into other languages, original can original content itself can be in other languages. In fact, I ask all the people I ask whenever I give this talk I always ask supposing there is a problem that a tenth or eleventh grade child understood. Some problem methodology it has to be conveyed to the other classmates who is a better person to do that is that child who understood that or a noble law rate. So, the answer is always clear it is always that the person at that level who has understood because they know what is known to them will explain everything in a way they can classmates can understand. So, it is great for community participation as well. So, 80 to 90 percent of the public who are now left out of the IT revolution. So, I argue that about 90 percent of our children have become second class citizens because they do not have access to IT. If you look at all new initiatives they are all IT based they are all IT based. Now, for example, if you want to book a ticket IRCTC.CO.in you do not have to go and stand in the queue. Another example I mean this is the entrance exam time. So, my daughter is you know applying for Jipmer to you know entrance exam medical entrance exam for Pondicherry. They make the application available only from Pondicherry. So, you have to send a DD by post to them and then they will send the form and then you fill it and send it again. So, this there are three the three legs involved through post, but if you have access to internet you can download the form fill it get it certified and send one only once. So, obviously the person who has access to internet is at an advantage. So, in every one of the things web checking checking the weather checking the commodity prices you name it it is all through IT. So, I believe that we have already made you know if we have not made we will be making most of our children into second class citizens because they do not have access to internet. Now, the point is that of course some you know there are some efforts to convert the whole thing even the screen and so on into local languages, but the problem is this children always want to know that if I study IT in my local language will I get a job in Infosys, will I get a job in TCS and so the answer is almost always known. A person who knows English is certain advantage that is the reason that everybody wants to learn in English. So, in our technology the screen is the same and all our children are taught English. In fact it is a very sensitive topic you tell somebody go and learn in Marathi first thing you will ask is in what language are your children studying why do you want me to study in Marathi. So, this technology actually is turns out to be very convenient from that point of view also hopefully the children who use this will also pick up English which is something that everybody wants to. So, this is something that I have talked about there is only one thing that I want to show in this webpage and then I will conclude. In this spoken tutorial activity I believe that we need to create of the order of 10,000 spoken tutorials each of 10 minute duration to cover all open source software and to be dubbed into each one to be dubbed into 20 languages. So, we are talking about a need to create something like 2 lakh spoken tutorial. If we create if it costs 1000 rupees to create them to create once spoken tutorial of 10 minute duration I am saying there will cost there is a budget of 1000 rupees. One can say why should it cost 1000 rupees it should be used by 1000 people. So, unless it is a good quality unless it is correct unless it is pedagogically sound people are not going to use. So, if it is a project of it is a national project we have to make sure the quality is good in order to ensure that we need to spend that money. So, we are talking about 2 lakh spoken tutorials to be made each one costing about 1000 rupees. So, what is the total cost it comes to 20 crore. So, if you have if you spend 20 crore we can cover all open source software and made of make them available also in all Indian languages I am talking about 20 Indian languages. Where is the man power how are we going to create these 2 lakh spoken tutorials. So, we have the workforce supposing I give some kind of a stipend to a student at a cost of a stipend of 25000 rupees a year. In return the student will create 2 spoken tutorials a month 2 spoken tutorial each one of 10 minute duration it is not too long right. So, it is do open. So, a student can do. So, 25 spoken tutorials 24 spoken tutorials we pay them 25000 rupees a stipend. If 100 students do this it will cost 25 lakhs can be find 100 students we can find 100 students even in IIT Bombay 25 lakhs. If I find 1000 students supposing I open it up for all over the country it will cost 2.5 crore. So, in 8 years it can be done the 20 crore. Now of course, I am not including housewives retired people professionals unemployed people and so on. If you include we can do it faster of course, that 10000 is just a number that we will eventually want to make it, but initially even 1000 will cover quite a few things how to browse how to buy a ticket through IRCTC stuff like that many of those things can be covered very easily. So, it is doable, but it requires lot of administration we are talking about a demand we are talking about a workforce how are we going to do this. So, we are hoping to do this through this portal spoken tutorial dot bar g what I wanted to show was by the way this you might have noticed that this is done through through Pell. So, we have wiki and then we are in the process of identifying the SRS for this web page we have spoken tutorials website entity what is meant by a user what is meant by a script what is a video topic what is a video maybe I should make this bigger video revision video comments video links study plan software software resources bits bit comments bits application this is one link what are the spoken tutorial website processes user I mean these are all verbs video links video approval workflow bits creation of bits updation some of these have to be expanded. So, we are in the process of identifying the SRS for this and we have something called desired features we have to create a outline document with examples videos study plans bits external links search feedback what are the views seen by different people what are the use cases guidelines for creation then of course, we have things like what is a spoken tutorial how to write a script for a spoken tutorials guidelines for narrating a spoken tutorial both original and dubbed version guidelines for screen casting a spoken tutorial. So, various forms and so on. So, you can see that. So, we are in the process of identifying SRS for this because it is a huge activity we are talking about two lakh creation of two lakhs spoken tutorials to be reviewed for correctness accuracy and so on and we have a big workforce how are we going to make this together. So, we are planning to use Drupal for this purpose planning to use the community activities like Facebook and so on and so forth various things we need to use everything and I strongly believe that through this technology we can make our children all our children IT literate whether the because IT is not rocket science how to use web how to browse web how to buy a ticket through IRCTC if you explain it to anybody they can do it. So, why not make this available to our children. So, that is the objective of this thing I would want you to participate. I think I have come to the end of this let me just include. So, funding for our work has come from the National Mission on Education through ICT you can also get funding see this site that I gave earlier. So, open source efforts are not only idealistic they also make economic and commercial sense as well it has a potential to empower all our children to collaborate and make us a developed nation and IIT Bombay is working on several open source projects we invite you to join us. Thank you.
