Touchless enables touch without touching by using a webcam to track color based markers. Touchless includes two parts:
- Touchless Demo is an open source application that anyone with a webcam can use to experience multi-touch, no geekiness required. There are 4 fun demos: Snake - where you control a snake with a marker, Defender - up to 4 player version of a pong-like game, Map - where you can rotate, zoom, and move a map using 2 markers, and Draw - the marker is used to guess what.... draw!
- Touchless SDK is an open source SDK that enables developers to create multi-touch based applications using a webcam for input, geekiness recommended. Touchless is an SDK that allows users to create and experience multi-touch applications. Touchless started as Mike Wasserman’s college project at Columbia University. The main idea: to offer users a new and cheap way of experiencing multi-touch capabilities, without the need of expensive hardware or software. All the user needs is a camera, which will track colored markers defined by the user.
This project is an Office Labs community project :Project Touchless
