Abstract
An optical sensor for detecting at least one of proximity and gesture is disclosed. The optical sensor is configured to detect or sense an object that is located out of the sensor's primary axis. This off-axis detection is facilitated by projecting light emitted by a light source away from the sensor's primary axis and away from the direction in which the light was originally emitted by the light source. The light detector is also configured to detect the light that is being projected off-axis.
