20120139449 | Movement-Based Feedback Device - An apparatus is provided that includes a substrate and an affixed accelerometer configured to measure acceleration of the substrate, and produce a signal representative of the measured acceleration. The apparatus also includes a light-emitting component capable of emitting multiple colors of light with variable luminosity, with the color and luminosity of light emitted by the light-emitting component defining a visual output produced by the light-emitting component. And the apparatus includes a processor coupled to the accelerometer and light-emitting component. The processor is configured to receive the signal from the accelerometer, calculate a visual output according to an algorithm as a function of the measured acceleration of the substrate, and cause the light-emitting component to produce the calculated visual output. | 06-07-2012 |
