The first signs of Microsoft’s Kinect integration for Windows 8 appear to have been discovered, according to reports.
Microsoft is expected to include some Kinect-like features in Windows 8 to take advantage of webcams and future webcam based sensors. Details of such integration leaked to the Internet in a number of slides in June, 2010. Microsoft appears to be building this integration into early builds of Windows 8. Windows8italia posted details of Windows 8′s Sensors control panel which includes references to “Detect Human Presence”.
Microsoft’s original leaked slides promised the ability for a webcam to detect a users presence and log them in automatically:

The discovery of the same terminology appears to confirm that Microsoft is experimenting with the integration of Kinect-like facial detection as a Sensor inside Windows 8. Microsoft uses the Kinect camera to automatically detect Xbox LIVE users and sign them into various services. The promise of similar functionality in Windows could mean that users will be able to simply switch desktops by sitting in front of the PC, as promised in the previously leaked slides:

It’s not yet clear whether the integration will require a special webcam similar to the Kinect device which includes a depth sensor and full-body 3D motion capture.
