Sensors

Sensors & location platform Simple interfaces enable Metro style apps to adapt to the

surrounding environment

Sensor fusion opens up new possibilities for creating cutting edge experiences in Metro style apps

Windows 8 provides a consistent sensors and location hardware foundation

Windows 8 ensures consistency between different systems to ensure that apps just work

Basic app scenarios for sensors

Shake Rotate Flip

Light-aware apps – render for lighting
