Interactive Projector Screen: Low-Cost Webcam Implementation

Video Title :	Interactive Projector Screen: Low-Cost Webcam Implementation
Description :	We converted an ordinary projector screen into an low cost interactive screen using a webcam. This is one of the several applications from our "Interactive Computer Interface using Webcam" proejct. Here's some of the demos used during our project presentation to illustrate our prototype. The projector and screen are ordinary ones like any others in our labs. A webcam is used to detect the presence of any lightspot on the projector screen. A program running on the computer then finds out the position of the lightspot on the screen and uses this info to control the computer's mouse cursor. As shown in the video, our prototype is able to work with the following light pointers: 1. any ordinary laser pointer (i.e. red light spot) 2. an ordinary pocket torchlight (penlight) 3. specially built infrared lightpen 4. infrared presentation pointer/stick. Our prototype is able to operate most (not all!) standard WinXP applications and several video games (more info on other videos). This is demo video#3 for the "Interactive Computer Interface using Webcam" project by our Audio-Visual Project lab, Elect. Eng. Div, Ngee Ann Polytechnic, Singapore.

wow dude that was awsom send me the sites that you downloded does things from plz =)

What constitutes a click?

where can you get the camera to do this

hi mr loh, this project looks great. i've visited your project website on blogspot and i gather that u are using just a webcam to do tracking. i understand how you can track the IR lights but how do u track the red lasers? r u using a filter attached to the webcam to allow u to track the red lasers? Could u elaborate more on your calibration process? Thanks!

This is really nice, but expect interruptions. The class clown is bound to have his own laser pointer, and would have no qualms with using it.

thanks, ben ... shouldn't u be studying on ur exam, ah? :)

Nice1 Mr Loh...haha....
