Embodiment Construction

[0027] Below in conjunction with specific embodiment the present invention is described in further detail:

[0028] Such as figure 1 or figure 2 As shown, the technical solution of the present invention is: a user interaction interface of 3D virtual projection and virtual touch, which includes the following components:

[0029] Depth detector 1: used to detect the distance information between the user's head and hands and the 3D display device 4;

[0030] Binocular image parallax calculation module 2: Calculate the binocular image parallax of the user interface through 3D display virtual projection to the arm length range from the user's head according to the received distance information;

[0031] Binocular image processing module 3: process the images displayed by the left and right eyes to reach the binocular image parallax calculated by the binocular image parallax calculation module 2, and then send the processed image to the 3D display device 4;

[0032] 3D display d...

Abstract

The invention discloses a three-dimensional (3D) virtual projection and virtual touch user interface and an achieving method. The three dimensional virtual projection and virtual touch user interface comprises a depth detecting device, an eyes image optical parallax calculation module, an eyes image processing module, a 3D display device, a gesture identification module, a camera and a virtual touch controller. The depth detecting device detects to obtain distance information between the head and the hands of a user and the 3D display device, the eyes image optical parallax calculation module calculates eyes image optical parallax according to the distance information, the eyes image processing module processes an image according to information of the eyes image optical parallax and sends processed image to the three dimensional display device to be virtually projected in a scope of arm length of the user, the gesture identification module identifies user finger moving tracks through the depth detecting device and the camera, the virtual touch controller conducts corresponding reactions according to gestures and the moving tracks of the user. The 3D virtual projection and virtual touch user interface not only achieves the 3D virtual projection and virtual touch user interface with feedbacks, but also brings the user interactive experience which is convenient to use and novel.

Description

technical field [0001] The invention relates to a display device, in particular to a user interaction interface and a method for realizing 3D virtual projection and virtual touch in the display device. Background technique [0002] At present, there have been touch operations realized on virtual screens, but virtual touch operations have not been realized on the user interaction interface of 3D virtual display. [0003] For example, the patent number is 200910197205.2, and the patent name is "a visually operable non-physical touch screen system", which discloses a visually operable non-physical touch screen system. The system consists of a computer, two network cameras , a head-mounted display, and a calibration reference object, which calibrates a virtual touch screen. Users can observe the real world with a virtual touch screen through the head-mounted display. And the touch screen without entity can be directly operated by hand. The present invention adopts two cameras...
