Abstract:
1. A device comprising: at least one tilt sensor configured to generate tilt sensor signals indicative of at least a forward/back tilt angle of the device and a left/right tilt angle of the device; a context information server configured to receive the tilt sensor signals and determine whether the device is in an upright portrait orientation, a landscape orientation, or a non-upright portrait orientation, based on the forward/back tilt angle and the left/right tilt angle; and a processor configured to increase a power mode of the device in response to each of: the left/right tilt angle being in a first specified range, the forward/back tilt angle being in a second specified range, and the device being in the upright portrait orientation rather than the landscape orientation or the non-upright portrait orientation.
