Recent advances in sensor technology are catalysts for the acceleration and evolution of user experiences on PCs. The ability to react to changes in ambient light, motion, human proximity, and location are becoming common and essential elements of the computing experience. Even something simple—like an ambient light sensor to adjust display brightness in a room with changing light—is potentially a basic scenario for desktop PCs. Of course, we also want to make sure you have full control over the use of these peripherals, since we know that different sensors leave open opportunities for risk or abuse that some folks might not be comfortable with. This post looks at the details of supporting sensors in Windows 8 and was authored by Gavin Gear, a PM on the Device Connectivity team.
