Abstract
A handheld electronic apparatus includes a housing, a plurality of touch sensors, and a controller. The controller under power saving mode activates parts of touch sensors to execute a touch detection action.
Claims16
A hand-held electronic apparatus, comprising:
- a housing;
- a plurality of touch sensors, disposed on at least one lateral side of the housing, wherein the touch sensors comprise a plurality of first touch sensors and a plurality of second touch sensors;
- the first touch sensors are disposed on a first lateral side of the housing, and the second touch sensors are disposed on a second lateral side of the housing, wherein the first lateral side is opposite to the second lateral side;
- a controller, coupled to the touch sensors,
- wherein the controller under a power-saving mode selects a part of the first touch sensors to be a plurality of first selected touch sensors, selects a part of the second touch sensors to be a plurality of second selected touch sensors, and activates the plurality of the first selected touch sensors and the plurality of the second selected touch sensors in an alternating sequence,
- wherein in the alternating sequence, only one of the plurality of the first selected touch sensors is activated and followed by activating only one of the plurality of the second selected touch sensors.
