I have downloaded the Livestreaming App for the SmartEyeglass and I want to enter certain things to it but I don't know how.For the App to work you need to install it to your phone and open the localhost web page in your computer.In the localhost web page, there is a camera view which displays what the wearer of the Smarteyeglass is seeing and a textbox in which you can write what you want the wearer to see. In this webpage I want to add another textbox in which I will be able to take feedback from the wearer.But I have no idea in which part of the code I can add that. Can you help me? How do I change the layout in the localhost webpage?
