DETECTING GESTURES ON THE SIDE OF A COMPUTING DEVICE

摘要

Embodiments of apparatus and methods for detecting gestures are described. In embodiments, an apparatus may include a transmitter-receiver electrode arrangement to generate an electric field projecting beyond a side of a computing device, so that changes to the electric field caused by user gestures on or near the outer surface of the side may be sensed. The transmitter-receiver electrode arrangement may include at least a transmitter and a receiver that are different, but complementary in geometry and disposition, disposed relative to an inner surface of the side of the computing device. Moreover, a capacitive sensor may be disposed in the computing device to output electrical signals indicative of changes to the electric field sensed. Other embodiments may be described and/or claimed.

1. An apparatus, comprising:
a transmitter-receiver electrode arrangement to generate an electric field, wherein the transmitter-receiver electrode arrangement includes at least a pair of transmitter and receiver electrodes that are different, but complementary, in geometry and disposition, disposed relative to an inner surface of a side of a computing device, to enable the electric field to project beyond the side, and changes to the electric field caused by user gestures on or near an outer surface of the side be sensed; and a capacitive sensor disposed in the computing device, coupled with the transmitter-receiver electrode arrangement, to output electrical signals indicative of changes to the electric field sensed.
