So we all know of all the different setups; we have a lot of them, in fact! For example, there’s DI, DSI FTIR… and the list goes on and on. But all of them are so bulky, am I right? For the webcam to view the surface or the whole surface I should say, sometimes takes a good 3 feet depending on size. Well, I didn’t like that idea. Bulk is not my style. Instead, I got to thinking about a new idea, and I came to call it MTXY. In theory, I believe it will work. Here’s how it is set up:
1.) acrylic, with IR LED’s or lasers along the sides, just like a normal FTIR setup
2.)LCD matrix with IR filter removed
3.)some type of IR stand still material (something to make a beam of visible IR light in itself to the camera) —webcams are on the sides
The cameras would capture the sides of the acrylic and based on the horizontal rule of the emitted IR, it will put the X and Y coordinates there with the proper functionality. Of course the program deciphering would have to take just the top layer of the camera’s image so that it would process coordinates for just the width of the acrylic… (or would it matter ???)
I’ve included some Paint mockups as well. Maybe these will clarify what I’ve been thinking about over th apst few days. I just have one problem with this setup; What am I going to use for #3?? I can’t think of anything right now, but I’m sure maybe one of you all will think of something...(maybe). Hopefully this could be a working concept some day and make mutlitouch displays small enough width-wise to the point where they’re the size of a regular non-modified LCD monitor.
Please tell me what you think, I’m very interested for some feedback, even if it is negative… :D
Thanks for reading!
