Abstract: A keyboard having multiple layouts includes depressible keys. A light reflector is positioned under at least some of the depressible keys with light sources configured to emit light towards the light reflectors. The light impinges on one of a plurality of reflective surfaces of the light reflectors and is reflected towards a corresponding depressible key under which the light reflector is positioned to cause a character or symbol to appear on a surface of the depressible keys. A switch allows a user to selectively control the character or symbol appearing on the surfaces of the depressible keys, resulting in more efficient input for the multiple layouts that improves the user experience.

Abstract: A control system includes a housing engaged to a mounting surface, a sensor contained within the housing, a server in communication with the sensor, and a terminal device in communication with the server. A gesture by a user associated with the mounting surface controls activity of the terminal device, such as a knock on a wall lowering a thermostat. The control system enables a mounting surface independent from the terminal device to become a controller for the terminal device. The sensor forms an interactive zone, and a contact interaction with the mounting surface within the interactive zone is detected by the sensor as data signals. The server receives the data signals, determines a data pattern corresponding to the data signals, and matches the data pattern with a gesture profile. The gesture profile is associated with a command transmitted to the terminal device to control activity of the terminal device.
