Embodiment Construction

[0035] figure 1 A block diagram showing an input device installed in a motor vehicle according to the present invention. The input device comprises a sensor panel 1 in the form of a touch screen with a matrix display, in particular a liquid crystal electronic display. Said sensor panel comprises a large number of pixels, the brightness and / or color tone of which can be individually controlled by the control unit 2, in order to be able to represent arbitrary pictures or images on the sensor panel 1, the graphic elements of which comprise a large number of such pixels and which can be e.g. These are keys or controllers 3 of the device to be controlled via the input device. exist figure 1 In the schematic diagram of , the pixels are controlled for a plurality of sliders 3 , for example simulating a sound enhancer.

[0036]When the sensor panel 1 is touched by an external object, especially a user's finger 4 , the sensor panel transmits a position signal to the analysis unit 2 ...

Abstract

An input device for controlling a device is provided. The input device comprises a sensor surface sensitive to being touched by a foreign body, and an evaluation unit, which is equipped to sense the positions of successively touched points of the sensor surface, and convert them into a control command for the device. The evaluation unit is connected to means for estimating an acceleration acting on the sensor surface and equipped, when converting into the control command, to weight a point touched at a time of intense acceleration change lower than a point touched at a time of slight acceleration change.

Description

technical field [0001] The invention relates to an input device, in particular for controlling an electronic device in a motor vehicle. Background technique [0002] So-called touch screens are becoming more and more popular as input devices for electronic devices such as mobile phones, microcomputers, entertainment electronics, etc., because touch screens allow comfortable and clear control of numerous functions without the need for expensive installation of numerous switches, adjustments, etc. device or other input. In other words, an image of such an input element can be displayed, for example, on a touch screen, and the user can make an input by flicking the displayed image of the switch with his finger or sliding it over the image of the slider, and thus Mimics the movements he would perform when operating a real slide regulator. [0003] Another input scheme does not need to display the input at all. For example, there are such solutions, which are based on the idea...
