ABSTRACT:
A capacitive touch sensor is provided having sensing path for setting a color parameter to a desired value within a range, the color parameter being color hue, color saturation or color temperature. The sensor includes a sensing element having a sensing path, a terminal connecting the sensing element to a sensing channel, and a processor configured to interpret a signal indicative of a capacitance of the terminal. The processor has a first mode configured to set a parameter to a desired value. The desired value is related to a first position of an object sensed along the sensing path and a range of parameter values mapped to a length of the sensing path. A second mode adjusts the parameter based on a displacement of the object along the sensing path.
