TL;DR: What is the best way to accurately do IR point tracking, and send that info over serial?
I am working on a project that needs a physical user interface. I need need to be able to track user input on a wall such that they could "click and drag" a projected image. I think that the best way to do this is with some kind of infrared blog tracking and an infrared pen for input. I would like to reveal the position information to a computer over serial, as this would be the easiest to access from a web browser (a vital part of the project). Bluetooth will not work because I can't access that connection from a web browser.
I have of course seen all of the various Arduino + WiiMote sensor blob tracking, though it seems that all of the support out there for that kind of thing is horribly outdated. I bought all of the stuff required and wired it all up but I just can't seem to get it to work.
If you're unfamiliar with the WiiMote stuff:
I want to do the processing onboard the arduino and just send the actual detected point information to the computer to minimize cpu load.
Can anyone think of an alternate route to reveal IR blob position fairly accurately over serial? Basically I need to emulate a whiteboard digitally, and any method to accomplish that would be welcome. Alternatively if anyone currently has a WiiMote IR camera setup working I would love to hear about it.
I used to do a whole lot with arduinos, but I have gone almost totally to the software side of things for a few years so this is all pretty foreign to me. At this point I am so frustrated that I would rather pay someone for the hardware then mess up yet another circuit myself, but this is not the correct forum to discuss that and I will repost once I settle on a circuit design.
Thanks in advance!
