Microsoft Touchless (via Shell City) is an interesting application that fits well into the touchscreen craze that Microsoft started with the Windows 7 announcement. Everyone knows that Windows 7 will provide better support for touchscreens. Users without a touchscreen could make use of Touchless which utilizes a webcam to provide a touchscreen-like experience.

A Touchless demo can be downloaded from the Office Labs project page which contains four demonstrations. Snake is the well known snake game while Defender offers a up to four player pong experience. Map is a basic map application which supports rotating, zooming and moving while Draw lets the user draw on the screen.

Touchless requires a computer running Windows XP or Windows Vista and a webcam that is DirectX9 compliant. The application can be started by extracting the contents of the archive to the computer system and double-clicking on TouchlessDemo.exe.

Microsoft Touchless provides access to the Touchless SDK which can be used to create third party applications that make use of the system. The whole package is Open-Source and could provide a way to add basic touchscreen support to webcam owners in Windows 7 which would surely explode the number of users that would make use of the Touchscreen features.
