Abstract
A device, for example a mouse pad, configured to illuminate, fluoresce, or glow depending upon user input or user motion. The pattern, format, shape, and/or direction of illumination by the mouse pad depend upon user-directed motion of an input source relative to the mouse pad. For example, the illumination pattern or profile of the mouse pad can depend on user-directed motion of an illumination source, for example a LED source carried by an optical mouse, relative to the mouse pad. The mouse pad includes a first layer that includes a first luminescent composition and a second layer that includes a second luminescent composition. The first luminescent composition and the second luminescent composition can have different luminescent properties or characteristics. The first luminescent composition and the second luminescent composition can be selected for establishing or providing the mouse pad with a desired, intended, or target set of illumination characteristics. The ratio of the first luminescent composition to the second luminescent composition can also be selected and/or varied to provide the mouse pad with a desired, intended, or target set of illumination characteristics.
