The Gira System 3000 Touch Top Unit can be used either as a dimmer or blind controller. The desired brightness or blind position can be infinitely adjusted by swiping a finger over a touch-sensitive light bar, with the LED display providing feedback on the lighting or shading status. Brightness values and blind positions can be stored and directly called up via three additional control points. During the development of the device, attention was paid to a simple operation so that it is applicable for accessible living areas.
