[Not bug] - [Idea] - Full touch screen #13

Hey there, I was discussing this awesome project with one of my friends and he asked me why it was limited to a certain portion of the screen. I told him it's because of the field of view of the camera and mirror combined is limited.

So he gave me a piece of advice that you should look at this problem from the industrial design point of view. Basically ask someone who is good in the industrial design field, whether is it possible to design a mirror which can cover the whole screen and reflect it in webcam!!

And I must tell you this, that this is one of the coolest outcomes I've seen of a hackathon. Good job dude. Let me know if you have any question regarding this idea.

We looked into this a few years ago. It's likely possible to design a custom optical path that covers the entire screen using some software such as Zemax (https://www.zemax.com/).

Unfortunately one-off custom optical components tend to be fairly expensive (though they can often be injection molded at scale).

If you're interested in taking this project on, that'd be sweet. Let us know!
