[0002] Touch screen (touch control screen) is an important part of the human-computer interaction in the prior art. The existing touch screen input depends on the physical touch screen device, that is to say, there must be an actual touch screen. Only the control screen can complete the human-computer interaction, which greatly limits the scope and conditions of the place for human-computer interaction

The invention provides a man-machine interactive type virtual touch device, system and method. The method comprises the steps that hand recognition is carried out on image data collected by a camera with a single hand of a user horizontally arranged on an image capturing area in a hanging mode, and therefore the position of the central position of the hand in an image is determined, the camera resolution degree is combined, and the pixel position of the central point of the hand is converted into a two-dimensional coordinate value of an XZ coordinate surface and a two-dimensional coordinate value of a YZ coordinate surface, so that the coordinate value of the central point of the hand in an XYZ three-dimensional coordinate system is set, when the coordinate X of the central point of the hand is judged to fall in an X-coordinate area of an operational icon, the value Y of the coordinate value of the central point of the hand is compared with an Y-coordinate area in the operational icon to determine the operation mode, an operation result of the hand of the user can be determined according to the working mode and the operation mode, according to the operation result and coordinates of the operational icon, a picture for virtualizing the position of the hand on a touch screen and effective operation is drawn, and the drawn image is displayed. According to the man-machine interactive type virtual touch device, system and method, the user can conveniently perform free man-machine interactive operation through the virtual touch screen any time any where.
Description
technical field [0001] The present invention relates to the field of virtual touch technology, in particular to a human-computer interactive virtual touch device, system and method. Background technique [0002] Touch screen (touch control screen) is an important part of the human-computer interaction in the prior art. The existing touch screen input depends on the physical touch screen device, that is to say, there must be an actual touch screen. Only the control screen can complete the human-computer interaction, which greatly limits the scope and conditions of places for human-computer interaction. Contents of the invention [0003] In view of the above problems, the present invention provides a human-computer interactive virtual touch device, system and method that overcome the above problems or at least partially solve the above problems. [0004] The present invention provides a human-computer interactive virtual touch device, including a display control unit and a ...
