Touchless SDK Posted on Codeplex By Jeffrey Schwartz 10/17/08 Software that started as a project by a Columbia University computer science student to eliminate the need for multiple hardware-based touch interfaces is now available for download on Microsoft's Codeplex site. The Touchless SDK was designed by Michael Wasserman, now a member of Microsoft's Office 14 development team, to let programmers use a webcam as a graphical input device. With the SDK the webcam can track the movement of a physical object defined by an individual. A video demonstrating the Touchless concept is available on the Codeplex site.
