The Microsoft Touch Mouse Sensor SDK is now resurfaced on the Microsoft Research download site in both 32-bit and 64-bit flavors.
"The Microsoft Touch Mouse supports multitouch gestures via an integrated sensor. The Touch Mouse Sensor API software-development kit (SDK) is a small library intended to enable students and researchers to experiment directly with Touch Mouse sensor output," mentions the description of the SDK.
Using this SDK, you can create your own applications consuming the 13 x 15 sensor image.
The SDK includes C# and C++ samples demonstrating how to read and manipulate sensor data.
To use this SDK, you need Windows 7, Visual Studio 2010, and a Microsoft Touch Mouse.
This SDK is provided for research and educational purposes only, not for commercial use.
