Abstract
A portable electronic device includes a motion sensor and a controller. The motion sensor detects an alternating signature motion of a limb of the user about a virtual axis corresponding to the limb. The motion sensor may be an accelerometer capable of detecting three dimensional acceleration. The accelerometer detects acceleration along X, Y and/or Z axes, in which acceleration peaks of the X and Z axes alternate with each other and acceleration of the Y axis remains substantially steady relative to the X and Y axes. The portable electronic device controls at least one function based on the detected alternating signature motion of the limb and/or acceleration along the X, Y and/or Z axes.
