Abstract: Systems and methods for providing a self-aligning user interface in a mobile electronic communications device having a touch sensitive surface include detecting a finger touch on the touch sensitive surface and determining an angular orientation of the touching finger in a continuous angular coordinate system. A user input orientation is assigned to the touch sensitive surface such that it matches the angular orientation of the touching finger. When a finger gesture is detected on the touch sensitive surface, it is then interpreted by reference to the assigned user input orientation.

Abstract: An electronic device includes a first device housing and a second device housing, with a hinge coupling the first device housing to the second device housing such that the first device housing is pivotable about the hinge relative to the second device housing between a closed position and an axially displaced open position. At least one inertial motion unit is situated in the first device housing and determines an orientation of the first device housing in three-dimensional space, delivering the same in an orientation determination signal. An inertial motion unit adjustment engine, activated by at least one predefined condition of electronic device, can apply at least one correction factor to the orientation determination signal when activated to create a modified orientation determination signal.

Abstract: Systems and methods for calibrating presence and gesture detection thermal sensors in a mobile electronic communications device entail sensing an ambient temperature and designating the sensed ambient temperature as room temperature, and determining that a user appendage has touched, or is close to but not touching, the thermal sensor. If the user appendage has touched a lens of the thermal sensor, a sensed temperature just prior to that event is used as hand temperature. If the user appendage is close to but not touching the lens of the thermal sensor, the temperature during that event is used as hand temperature. A difference between the hand temperature and the room temperature is then determined and the presence and gesture detection functions for the device are calibrated based on the determined difference.
