Have you ever wanted to do something, and someone else beat you to it? (or saved you from the pain)
Here's a project:
where 'gleat' on codeproject.com wrote a Windows 7 Sensor Platform driver for the Nintendo Wii-mote (using Bluetooth HID). This project demonstrates how it doesn't really matter what type of device you're using, the sensors can be exposed via the Windows Sensor Platform if you have access to the data via an understood protocol. Now you can write apps for Windows that can use the Wii-Mote, or other accelerometer hardware such as the Windows 7 Sensor Development kit without any special knowledge of the hardware specifics in your app.
