Electronic device control in response to finger rotation upon fingerprint sensor and corresponding methods
An electronic device includes a fingerprint sensor and one or more processors operable with the fingerprint sensor. One or more motion detectors are also operable with the one or more processors. The one or more processors determine with the fingerprint sensor, a direction of rotation of an object rotating, and in contact with, the fingerprint sensor. The one or more motion detectors detect whether the electronic device is rotating in three-dimensional space. The one or more processors then select and perform a first control operation when the object is rotating in a first axial direction and the electronic device is substantially stationary. Alternatively, the one or more processors select and perform a second control operation when the electronic device is rotating and the object is rotating in the first axial direction.
