Hi all, I'm looking to get started with a multitouch project using stereovision. Since I'm only interested in 2D for the moment I'm looking for a cheap line scan camera that I could use for the project. Ideally with an Arduino or that I can directly plug in the computer. The idea is to put 2 cameras in the top corners of the diplay that will be able to detect a finger touching the screen. Using the length of the finger image and a bit of trigonometry I can work out the position of the finger. More information on the project can be found here: https://www.physicsforums.com/threads/optical-touch-screen-code.825527/#post-5188484 Does anyone know where I could find such a camera. Also what is the difference between a line scan camera and a line scan sensor ? Cheers !
