<p>A control system 10, for controlling remotely one or more devices, comprises a sensitised area 11 for detecting the proximity of a hand at a plurality of points over the area, a gesture library memory, a gesture recognition module for recognising and identifying the hand's motions among gestures stored in the gesture library, and a controller 14 to control the operation of one of the devices according to the hand motions of an operator applied anywhere over the sensitised area 11. The sensitised area 11 may comprise an array of capacitive electrodes 12a-n arranged on a dielectric component 13 with each electrode 12a-n connected to a threshold circuit 21 a-n so as to independently adjust the sensitivity of each electrode 12a-n. The dielectric component 13 may be a laminated glazing panel and may be a windscreen. There may be provided a transmitting electrode (40, figure 4) placed in the vicinity of a steering wheel. There may be provided a head up display or display screen 15 to show the gesture to control each device. There may be provided a speaker 16 to provide audible feedback. The device may be a car air conditioner, radio or navigation system.</p> |
