Operating device, particularly touch pad for controlling functional units of motor vehicle, has operating input detected by finger, transmitting unit for transmitting signal to finger and receiving unit for receiving signals

摘要

#CMT# #/CMT# The operating device (10) has an operating input detected by a finger (20) and a transmitting unit (12) for transmitting a signal to the finger. A receiving unit (14) is provided for receiving the signals reflected from the fingers. A control panel element (18) is positioned spatially to the finger for performing an operation input. An evaluation unit (16) is provided for determining a spatial position of the finger to the control surface element based on the received signal. #CMT#USE : #/CMT# Operating device, particularly touch pad for controlling functional units of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The operating device has an operating input detected by a finger and a transmitting unit for transmitting a signal to the finger, where a receiving unit is provided for receiving the signals reflected from the fingers, and hence ensures simple and more effective operation of the operating device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of an operating device. 10 : Operating device 12 : Transmitting unit 14 : Receiving unit 16 : Evaluation unit 18 : Control panel element 20 : Finger.
