Color control intuitive touchpad
First Claim
1. lighting control touch pad system comprising:
- a variable color light source;
a computer having a control signal output to vary a hue, a saturation and an intensity of the variable color light source;
a two dimensional touch pad input device which sends a hue signal, a saturation signal and an intensity signal to the computer;
said hue and saturation signals derived from a first Cartesian axis coordinate and a second Cartesian axis coordinate of a touch on the touchpad in a color region of the touch pad input device;
said color region of the touch pad having a first Cartesian axis for a color spectrum (hue) in any chosen sequence of red, orange, yellow, green, cyan, blue and violet, each color represented within a colored overlay, and having a second Cartesian axis for minimal to maximum saturation levels of a selected color;
said color region of the touch pad having a color graphical overlay representing the colors of the color spectrum;
said intensity signal derived from an x and y coordinate of another touch in a separate intensity region apart from the color region of the touch pad input device; and
wherein the computer scans the touch pad input device to determine the coordinates of the touch and the another touch and via an algorithm creates the control signal output.

Abstract
A method and apparatus whereby a two-dimensional touchpad control for selecting color is implemented via a touch sensitive surface with a graphical attachment on its surface to select both an intensity and a color. The graphical attachment having two regions, one region being a rectangular shape to select the intensity via a Y-axis and the other being a two dimensional X/Y-axis control surface with color Hue on one axis and color Saturation on the other axis. Software running in a control device monitors touchpad regions for user inputs and converts the raw selected parameters on the touchpad into the Hue, Saturation and Intensity information, used in the preferred embodiment to control light fixture color and intensity.

12. A lighting control touch pad system comprising:
-
a variable color light source; a computer having a control signal output to vary a hue, a saturation and an intensity of the variable color light source; a two dimensional circular touch pad color input area in a touch pad device which sends a hue signal, and a saturation signal to the computer; said hue signal derived from a selection from a set of zones radiating from a center of the circular touch pad color input area; said saturation signal derived from a selected radial distance from the center of the circular touch pad color input area; said circular touch pad color input area of the touch pad device having a color graphical overlay representing the colors of the color spectrum; said intensity signal derived from an x and y coordinate of another touch in a separate intensity area apart from the circular touch pad color area of the touch pad device; and wherein the computer scans the circular touch pad color input area and the separate intensity area and via an algorithm creates the control signal output. - View Dependent Claims (13)
