Control apparatus (22) includes an optical subsystem (40), which is configured to direct first light toward a scene that includes a hand of a user (38) in proximity to a wall of a room and to receive the first light that is reflected from the scene, and to direct second light toward the wall so as to project an image of a control device (32, 34, 36) onto the wall. A processor (42) is configured to control the optical subsystem so as to generate, responsively to the received first light, a depth map of the scene, to process the depth map so as to detect a proximity of the hand to the wall in a location of the projected image, and to control electrical equipment (24, 26, 28, 30) in the room responsively to the proximity. |
