 Hello everyone, today I am presenting on fingerspelling, the sign language tool. As you all know that many of the research for the blind people has been already done like text TTY, you get on every phone, even the lift buttons that have brain. But what about the hearing speech impaired, hearing and speech impaired, they communicate in sign languages. So for sign language, now we don't know sign language. So for that we have created this tool, sign language app that will help you learn sign language and that will test you. You can learn, practice and test. So what the sign language does, in this application we have whenever you press a key on the keyboard suppose A, it will show you the corresponding sign language gesture that is of A and whenever there is a practice app or a test app that whenever you connect, whenever you press, whenever you have to check whether you are doing A correctly. So you get the camera feed, so you get the camera, so you choose your webcam of your laptop, you do the gesture in front of the laptop and it shows you the gesture of A. That's three modules, learn, practice and test. In learn, you learn how the gesture app works, whenever you, like suppose you press A key on the keyboard, it gives you gesture and animation of A. It has been made on Blender and Blender game engine. Not just that, not just that, we have posted the application online. So suppose few people don't want keyboard, so they can use the mouse and you click on the button that are below, there are buttons from A to Z, you click on A, it will show you the 3D module of A. So we went on the first to a school in Gorega. They teach sign language and we went to visit them and we had a good time. So they basically loved our app and they took all the files and they took the application and they requested that the application, the web application to be hosted so that they can use it any time they want. So I'll show you the game. So first is basically the instructions of the tool. So when you press A, it will give you the animation of A. B, similarly you can do it for S till A to Z basically. So we use the open free hosting, Hiroku, to host the app. So this gives you a 3D model that you can view even in VR. You can rotate, you can control the animation speeds. Another amazing part of this tool that we have developed is the image processing part. There are, research has been conducted by Microsoft that converts sign language but it doesn't teach you sign language. Moreover it requires XBox Connect that costs like 10,000 and other tools that are made for the sign language require like gloves and Arduino kit even that becomes costly because practically we have reduced the cost to zero. So this is the demonstration of the Python code OpenCV. This mode, learn and testing the OpenCV is under testing and it is still under development. Right now we have been able to build up to E. So this gives you a model of A. So like when you go, so you can see that there's A. Now sometimes due to the background noise it might be and low lighting it gets affected. Now you can see that the projector gets detected sometimes because even that's doing E and it's appearing over here. Something that's similar. It doesn't because C and D have the same thing. Like C is like this and D is like this. So the detection, I'll show you detection of D. So it's due to the noise, low lighting. So wherever D is detected it will make a box like you could see there's a blue box. Yes. So wherever D is detected, so like here, so there will be a blue box and there will be D written inside the box. Similarly for all the characters. So it is because of low lighting. So there was basically noise and due to that it was affecting. I'll show you the actual videos that we took that day when we went to Sanskar Dham. The school where sign language is taught. So this is a gesture detection. So they tried the detection app also. So you can see that B is getting detected, B, C. And like Sir said, that gesture of D and C is... Can you sign left or right? No, it's okay. So even if you do gestures with left hand or right hand. And this is also C. Yes. No, it doesn't get detected. Of course. That's it, sir. Thank you. Well, whenever you want to communicate in sign language, the grammar of sign language is very different. Like when I want to ask you like where are you? So I won't do the gesture of where are you? I'll just ask where are you? Just that much. So it won't make a difference because sign language works on the meaning of the sentence. Because right from the beginning when you are starting, you learn A, B, C, D. Sir, because you write exams. I am very sorry. I am very sorry. You do not start learning A, B, C, D from the beginning. Okay. Never. A child, English born child, American born child does not learn A, B, C, D. He says where are you? Ma, ma, pa, pa. Bread, omelette. That's all he learns. But what about proper now? I want. So, no, you said you start A, B, C, D. What I am saying is why are you starting teaching them A, B, C, D? We learn A, B, C, D for proper nouns. Like when I have to say my name is Tejas. So there's no gesture defined for Tejas. I have to spell out Tejas. That is, that is different. So for that you require. Actually, no. I can say Teja. That is good enough. Why that S is important? See, anyway he is not going to speak Tejas or Teja. What difference does it make? I can be anything. No, no, no. But, but, no. I'll explain, I'll explain you the same thing in a different scenario. You want to go from Andheri to Borivali. Now what will you do? I will, what I will do? Okay, I've got a car. I put the key and go. Okay, if I don't know I'll do Google map and that lady will keep saying turn right, turn left and I'll, that's it. Done, finished. And I can listen. Thank you so much.
