A gesture sensing device having a single illumination source is disclosed. In one or more implementations, the gesture sensing device includes a single illumination source configured to emit light and a light sensor assembly configured to detect the light reflected from an object and to output time dependent signals in response thereto. The gesture sensing device also includes a processing circuit coupled to the light sensor assembly and configured to analyze the time dependent signals received from the light sensor assembly to determine object directional movement proximate to the light sensor assembly.

An integrated circuit device includes an insulating body provided with a number of electrically conductive leads and having a surface provided with a red LED aperture, an IR LED aperture and a photodetector aperture. The insulating body also includes an optical isolator optically separating the photodetector aperture from the red LED aperture and the IR LED aperture. A red LED is aligned with the red LED aperture, an IR LED is aligned with the IR LED aperture, and a photodetector is aligned with the photodetector aperture.

Techniques in accordance with the present disclosure allow the detection of hover events and/or touch events performed over the touch panel without requiring that the touch panel be equipped with additional hardware and/or materials. In one or more implementations, the apparatus includes a touch panel controller configured to operatively couple to a touch panel sensor. The touch panel sensor includes at least one drive electrode and at least one sense electrode. The touch panel controller includes output circuitry operatively coupled to the at least one drive electrode. The output circuitry is configured to generate drive signals to drive the drive electrode (i.e., drive the touch panel sensor). The touch panel controller also includes input circuitry operatively coupled to the at least one sense electrode. The input circuitry is configured to measure mutual-capacitance between the at least drive electrode and the at least one sense electrode to detect a hover event. The present disclosure is directed to driving a subset of rows (or columns) and senses the subset of the remaining rows (or columns). Thus, the same sensor can measure multi-touch event and hover without changes to sensor pattern.
