I recently got myself into a new interactive topic called Multitouch Table. Like the Microsoft Surface table, it is basically a big multi point touch screen that allows user to interact with. Anyway, this project gets me really excited and I want to build one myself in the near future.
Multi-touch is a human-computer interaction technique and the hardware devices that implement it, which allow users to compute without conventional input devices (e.g., mouse, keyboard). Multi-touch consists of a touch screen (screen, table, wall, etc.) or touchpad, as well as software that recognizes multiple simultaneous touch points, as opposed to the standard touchscreen (i.e. computer touchpad, ATM), which recognizes only one touch point. This effect is achieved through a variety of means, including but not limited to: heat, finger pressure, high capture rate cameras, infrared light, optic capture, and shadow capture.
