  We introduce a novel approach to control physical lighting parameters by
means of a pressure-sensitive touchpad. The two-dimensional area of the
touchpad is subdivided into 5 virtual sliders, each controlling the intensity
of a color (red, green, blue, yellow, and white). The physical interaction
methodology is modeled directly after ubiquitous mechanical sliders and dimmers
which tend to be used for intensity/volume control. Our abstraction to a
pressure-sensitive touchpad provides advantages and introduces additional
benefits over such existing devices.
