Abstract
A method for determining whether a wireless device is being held comprising: activating a vibration motor in the wireless device to vibrate the wireless device for a predetermined period; receiving at least one acceleration measurement from an accelerometer in the wireless device during the predetermined period; 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 held wireless device.
Claims14
A method for controlling a feature of a wireless device comprising:
- determining whether the wireless device is being restrained by:
- receiving at least one acceleration measurement from an accelerometer in the wireless device;
- 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;
- and
- adjusting the feature in response to the determining, wherein the feature to be adjusted comprises an illumination intensity of a display of the wireless device.
2 more elements
A wireless device comprising:
- a processor coupled to a memory, a display screen, and an accelerometer and adapted for:
- controlling a feature of the wireless device by determining whether the device is being restrained by:
- receiving at least one acceleration measurement from the accelerometer 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, and adjusting the feature in response to the determining, wherein the feature to be adjusted comprises an illumination intensity of the display screen of the wireless device.
