Embodiment Construction

[0031] The technical solutions of the present invention will be clearly and completely described below in conjunction with specific implementation methods and accompanying drawings.

[0032] Such as figure 2 As shown, the multi-layer touch recognition device of the present invention includes a plurality of touch signal detection devices 1, 2..., N stacked, and a signal processing unit 20 connected to the plurality of touch signal detection devices 1, 2..., N, so The touch signal detection device sends detection data to the signal processing unit, and the signal processing unit processes the received detection data to obtain gesture data that can represent a three-dimensional touch gesture. The gesture data includes trajectory data in a direction not parallel to the display plane.

[0033] Described signal processing unit can adopt the single-chip microcomputer of multi-I / O interface to realize, also can adopt the single-chip microcomputer of single I / O interface, and describ...

Abstract

The invention discloses a touch recognizing device. The touch recognizing device comprises a signal processing unit and at least two touch signal detecting devices, wherein recognizing layers of the touch signal detecting devices are not positioned on the same plane; the touch signal detecting devices are connected with the signal processing unit and transmits detection data to the signal processing unit; and the signal processing unit processes the received detection data and acquires gesture data expressing stereoscopic touch gestures. The invention also provides a corresponding recognizing method and a man-machine interaction system comprising the touch recognizing device. Touching actions in stereoscopic space are recognized by using the multi-layer touch detecting devices, and stereoscopic touch gestures are recognized, and the touch recognizing device and the recognizing method can be well used for a stereoscopic display system or a stereoscopic operation system, for example touch operation of 3D (three-dimensional) images.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a device and method for performing touch recognition by using a multi-layer touch detection device. Background technique [0002] The application of touch screen is more and more extensive. Touch screen is an indispensable device for human-computer interaction. The current touch technology only provides analysis and application for plane touch actions, such as single click, double click and slide. However, in the prior art, in addition to providing flat images or menus, the display screen can also provide three-dimensional images. The current operation for three-dimensional images can only be performed after a series of selections with the mouse, which is very complicated and the operation efficiency is not high. high. With the in-depth development of display technology, there have been TVs and computers that use the principle of parallax for stereoscopic display, and many of them a...
