View topic - DIY multitouch plans & libs ! Regarding Microsoft's 'Surface', it's exciting but ... Quote: With a 30-inch screen, Surface will initially sell for between $5,000 and $10,000 (£2,525-£5,050). That's a bit expensive for me. The DIY option would be cheaper, the things you need are 1: a projector 2: a computer 3: a camera with a WDM driver 4: some infra red lighting (so it's out of the spectral range of the lightshow) 5: the table I guess cost depends to a large degree on whether you have a few items already. the camera they use is this one basically an OEM webcam / spycam device like I might buy from Maplin (UK) but why not get an all in one solution, camera and IR lights all in one. I'm guessing that the total (DIY) cost including the table would be £800 to £1000, but as the major cost is the projector if you already have one, then that would drop.
Webcam Based Laser Tracking for Human-Computer Inte I will be making use of Andrew Kirillov's motion detection code for image acquisition, and the AForge.NET framework, for certain image processing tasks. I'll start off by showing you how the image processing works for this program, and then I'll walk you through the important parts of the code. So, let's begin! Image processing and laser tracking... The laser tracking code works by finding the brightest pixel in the webcam's field of view. Image cropping is basically just trimming off the edges of an image to keep unwanted things outside the camera's view. The picture on the left is sampled at 20x20, and the image on the right is sampled at a higher pixel resolution, 100x100. The selection rectangle is a semi-transparent rubber band rectangle (picture above). Here's how you can make a rubber-band rectangle between two points (say x1,y1 and x2, y2): You will find this code in the ProcessFrame event in MotionDetector1.cs. Some notes on using the software Conclusion Have fun! About the Author

reacTIVision Johnny Chung Lee - Wii As of June 2008, Nintendo has sold nearly 30 million Wii game consoles. This significantly exceeds the number of Tablet PCs in use today according to even the most generous estimates of Tablet PC sales. This makes the Wii Remote one of the most common computer input devices in the world. It also happens to be one of the most sophisticated. Any software on this page is primarily meant for developers and may not run without proper the development tools installed. NOTE: For most of these projects, you don't need the Nintendo Wii console. Coming Later: 3D tracking, and more.... Unfortunately, time constraints in the next couple of months have significantly reduced my ability to work on more projects.
