Abstract:
A low-power pointing method and an electronic device are disclosed. In an embodiment, an electronic device includes a first processor configured to receive attitude quaternion data, indicative of an orientation of the electronic device in a 3D-space, generated by a sensor-fusion algorithm from joint processing of an acceleration signal, indicative of acceleration acting on the electronic device along three reference axes of the 3D-space, and of a gyroscope signal, indicative of angular rate of rotation of the electronic device about the three reference axes of the 3D-space, process the quaternion data to determine an orientation difference between a current orientation and a previous orientation of the electronic device in the 3D-space, translate the orientation difference from the quaternion space to a tilt-compensated angular rate of rotation of the electronic device in the 3D-space and generate screen-frame displacement data based on the tilt-compensated angular rate of rotation.
