Embodiment Construction

[0021] figure 1An embodiment of a device 20 according to the invention is shown with a digitizer 1 and a screen 9 behind the digitizer. The digitizer 1 is used in the operating mode to operate the GUI shown on the screen 9 . During periods of time when the user is not interacting with the device 20, the digitizer 1 and also the screen 9 are placed in a sleep mode and no power is supplied there. In sleep mode only the infrared LED 3 , the infrared sensor 4 and the capacitive sensor 5 can act as proximity sensing means to locate the user's finger 2 within a predefined vicinity in front of the digitizer 1 . In other words, the infrared sensor 4 and the capacitive sensor 5 are able to determine that the normal distance between the finger 2 and the digitizer 1 has reached or fallen below a predefined value. Via the data input 7 , the electronic controller 6 is provided as an evaluation unit to determine a predefined approach of the finger 2 and to switch the digitizer 1 and thus ...

Abstract

The invention relates to a device (20), a means of transport and a method for operating a digitiser (1). The method comprises the following steps: determining an approach of an input medium to the digitiser (1) without contact with the digitiser (1) by means of an optical sensor (12); and, in response, changing the operating state of the digitiser (1) from an idle mode into an operating mode.

Description

technical field [0001] The invention relates to a device for operating a digitizer, a vehicle and a method for operating a digitizer. In particular, the invention relates to a method for powering a digitizer on demand, so that the energy consumption for operating the digitizer can be reduced. Background technique [0002] Touch screens are known in the prior art, which receive touch-based user inputs and enable GUI (Graphical User Interface)-specific function calls. For permanently powered touchscreens (such as doorbell devices and touchscreens in vehicles), the touch-sensitive input surface ("digitizer") is permanently powered, so that the touch-sensitive input surface remains independent of the state of use. Ready to receive user input. This results in the digitizer also consuming power in standby mode or during periods of time when there is no user input. [0003] DE 10 2013 222 940 A1 discloses an operating unit having a capacitive sensor which is provided for detecti...
