User hand detection and display illumination adjustment for wireless device

摘要

A method for controlling a feature of a wireless device. The method comprises determining whether the wireless device is being restrained by receiving at least one acceleration measurement from an accelerometer in the wireless device and comparing the at least one acceleration measurement to at least one stored acceleration measurement, the at least one stored acceleration measurement corresponding to a predetermined restraining force on the wireless device. The method involves adjusting the feature in response to determining that the wireless device is being restrained. The feature to be adjusted comprises an illumination intensity of a display of the wireless device.
