CPC G06F 3/0416 (2013.01) [G06F 3/044 (2013.01)] | 20 Claims |
1. A control device configured for use in a load control system to control one or more electrical loads external to the control device, the control device comprising:
an actuation member having a front surface that defines a touch sensitive surface along at least a portion of the front surface;
a touch sensitive device comprising one or more receiving capacitive touch pads located behind the actuation member and adjacent to the touch sensitive surface, the touch sensitive device configured to detect a touch actuation along the touch sensitive surface; and
a control circuit configured to determine a position of the touch actuation along the touch sensitive surface in response to the receiving capacitive touch pads;
wherein the control circuit is further configured to use a filtering technique for the touch sensitive device for determining the position of the touch actuation along the touch sensitive surface, the control circuit configured to operate in an active touch mode when the touch actuation is detected and in an inactive touch mode when the touch actuation is not detected, and wherein the control circuit is configured to use the filtering technique with a first variable when the control circuit is in the active touch mode and use the filtering technique with a second variable when the control circuit is in the inactive touch mode.
