 Hi everyone, I'm Pooja Pariswani and today I'll be speaking about we are internet of things and their combination So when we are meets IOT life beyond second life So before that let me introduce myself. I'm a tech speaker in Mozilla and a social media specialist at Holgatech media and an electronics engineer So now coming back to the point What is virtual reality? So imagine you're you're you are reading a book and you start imagining yourself inside that book and you start imagining whatever Written and you start picturing yourself in your head. So that is actually virtual reality of an example of virtual reality You are basically dreaming, but you're but with your eyes open so Yeah, so now there are four Key elements which are required to experience the virtual reality The first one is the virtual world which you are going to explore. So this is a this is The picture or the scene you are going to explore to get the experience and The next is the immersion Which means you have to present you have to be present at do that into that virtual world both mentally and physically and Then comes the interactivity where you have to interact and show your immersion into that virtual world and Last but not the least is the sensory feedback since you are exploring that virtual world You are there you you are present into that World and you're interacting there should be some feedback So that feedback is sensory feedback, which is which can be in the form of audio video or sometimes in the form of motion So now Let's have a glimpse of how it all started. So in 90s The virtuality was there. They built a set of games for our kids So these were the actually the 3d games, which which allows you to play the games and they they were the They were present the malls, but Unfortunately, this is how it looked like and so the as you can see the graphics were so poor at that time So virtuality folded by the late 90s. So coming to the today scenario Yeah, so coming to this today scenario Nowadays, there are large number of startups venturing in virtual reality and A huge variety of VR Headsets are available in the market as you can see from the very cheapest and the simplest one Which is the Google the IY box to the very high-end one. You can use whatever you want according to your convenience and need so And All the credit goes to the smartphone era your smartphones today are so advanced that you cannot even they have so many features Available today that you cannot even imagine To get a go available in your high-end laptops or high-end computers devices so and everything in your phone is a smartphone is connected Connected to the cloud and speaking of cloud like In 2017 Around 98% of the VR devices sold were off or mobile devices So, yeah, mobile mobile set smartphone Hera has a huge impact in VR Virtual reality. So, yeah, speaking of cloud as so internet of things came into my into the frame and You can actually everything which is connected to the internet and Is communicating and sharing the data exchanging the data Comes into internet of things. So, yeah, these things now like like what is internet of things? So, yeah, things can be any devices which is connected to the internet and is sharing the data and Basically communicating with each other in into the form of the data See, yeah Then why iot why do we need it? So one of the One of the major promise of iot is to make world a smarter place Which can only be happen When you have the right information at the right time So, basically you have iot main motto is to give Access to all the information at the right time So, yeah, it's literally everywhere as As my as in the previous two talks you have already heard about the presence of iot It's literally everywhere. You just name a place and you find it already there be it your vehicle your home your Smartwatch refrigerators hospitals. Yeah So, yeah now these two technologies virtual reality and iot are separately a huge Booming so what wonders can happen when we combine these two? so the the foremost thing is the telepresence so Telepresence is actually like you make phone calls and you can send your voice at a distance So with the help of telepresence you can actually be at distance While not being there. So, yeah, in which we are will give you the vision and iot will give you the sense of here Hearing touch and control so and By combining these two together. You can actually open Were a door to a new whole new world so So With the availability of low-cost small size sensors you can you can enable the things in virtual reality Communicate to the things which are actually real. So The it's an ultrasonic sensor If if I use this as you can see it's very small and it is as cheap as $1 and by using this Small sensor. I can if I put this sensor in this this door So I can get the information about the state of the door like whether the door is open or it's closed Like how many times the door has been open or closed? So yeah, these all things you can actually do with this combination Yeah this is so I Along with my team we built a prototype of telepresence bot For farming purpose. So yeah, this is the picture taken by that bot So, yeah, and the prototype of the bot consists of an ordinal Which is connected to in Raspberry Pi. So basically the Raspberry Pi's The Wi-Fi in build Wi-Fi in the Raspberry Pi is giving commands to that ordinal and the ordinal is controlling the motors for the which and the motors are responsible for the motions and like and the and it and a camera is Mounted over the motors Having the pan and tilt motion. So the pan I'll show you the demo at the last how the pan and tilt motion works there and there are four sensors which are used as like a humidity sensors lights and soil moisture sensor and Temperature sensor and these sensors are actually the name itself Defining the functions of them and at the user end. There is a VR device headset along with a mobile device where the user can actually move his head and can see the field and see and see the actual Scene of that where the bot is being placed So, um Yeah, here I can explain you Some see the farming bot has the camera which is streaming the video of the field What's the main? scenario in this case, it's the field or agricultural field and the motions are The bot is moving left right up Forward and backward and the other one is for the camera pan and tilt So pan and tilt will work since the mobile devices you are using in inside your inside of your devices So when you move your head So it will move like that and you can see the and you can feel the virtual reality Your telepresence there and the sensors here are for the of measuring the various Parameters required for the agriculture So um, so the major advantage of this bot is that It is designed using the web server and which is accessible via internet So a farmer can log in and log in from anywhere in the world and can see the entire scenario of the field and can measure and can measure the the Various parameters and can see okay. What what is happening? What is actually happening at the field while not presenting actually at the field? so it can it can enable various it can enable the farmer to prevent the field from various threats like droughts and and floods and can also help farmer to maintain their field and in like in Ease of farming and it cannot actually provide the ease of farming So um, these are the few readings we got results and graphs we got from the bot So the soil reading Here says since the bot was moving towards the High moisture area from the low moisture area you can see the reading patterns here and The temperature reading here shows that a drop since the bot was in the functioning mode for eight hours So you can see the temperature down and up Since it was a span off from day to night and the light there shows Since the bot was moving it went under the shade so you can see the drop in the light and It was there the patterns shows that it was moving under the shed and it came out of the shed see Now apart from this farming and One of them what are the other applications of telepresence so There are many places which you cannot Which where the human presence is not actually possible or it's Really difficult even if it's possible. It's really difficult for humans to present at that time and there so like medical training and distance Education interactive learning and workshops and many other things can be done like mining maintenance is One of the most difficult thing where you human presence is like they are risking their lives So you can use telepresence for my mining maintenance and military in defense and many other applications can be Presence there and Since we and my team is my team and I are working on the prototype and for and we are adding more features to it So yeah, and also It's a best solution for a long-distance relationship. So yeah Okay, let me show you the demo for how it works the pan and tilt as You as you can I guess not visible here So as you can see as you're moving your head up and down and right and left the bots head is also moving See So this is how it works also an example of How you can solve your other problems as well So you can actually be there by not even being there So yeah, this is it any questions Yes It's it won't take much time. It's like it's really responsive when you move the head So yeah, it will show the exact response. So there is no more delay in that at least a negligible one You can say that I Sorry sorry Yeah for for inside the lab it was a Negligible one but for long distance here We have to test it because we haven't tested it yet, but yeah, there might be a delay, but not that much So yeah, there will be a like minor one, but not that much that yeah Any other questions? No more questions. Okay. So anyways If you feel like you have any other questions you can tweet me at so this is my Twitter handle You can tweet me. I'll be more than happy to answer all your questions So this is it for today. Thank you You
