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.

Self-aligning user interface

An electronic device detects ambient contextual data and positioning data such as orientation and motion to determine an activity state of the electronic device. A controller sets a polling interval of an open/closed position sensor that is connected to a movable portion connected to a base to detect an open/closed event. In response to determining a first activity state, controller sets a first polling interval that mitigates power consumption. In response to determining a second activity state, the controller sets the polling interval to a second polling interval that is shorter than the first polling interval to reduce latency in detecting the open/closed event.

In aspects of gesture detection based on device form factor, a device includes gesture detection algorithms from which gestures are detectable based on device configurations. The device implements a gesture module to determine a form factor of the device as one of the device configurations, and select a gesture detection algorithm that corresponds to the form factor. The gesture module then utilizes the selected gesture detection algorithm to detect a gesture performed by a user holding the device in the device form factor. Additionally, the gesture module can determine a change in the device form factor. The gesture module can then replace the gesture detection algorithm with a different gesture detection algorithm, or replace parameter values in the gesture detection algorithm with respective updated parameter values, which are then usable to detect another instance of the gesture performed by the user holding the device in the changed form factor.

Gesture detection based on device form factor

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.

A method, a mobile device, and a computer program product for determining orientation of a mobile device. The method includes detecting, via an accelerometer, movement of a mobile device and calculating, by a processor, an orientation of the mobile device based on accelerometer data received from the accelerometer as the mobile device is moving. The method further includes tracking the orientation of the mobile device as the mobile device moves over a period of time and maintaining an image capture device and a display in an off state, while the mobile device is moving. The method further includes determining if the mobile device is in a landing position, based, at least partially, on the calculated orientation of the mobile device and in response to determining that the mobile device is not in the landing position, continuing to maintain the image capturing device in the off state such that power consumption of the mobile device is reduced.

Determining orientation of a mobile device

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.
