Transparent display virtual touch apparatus not displaying pointer

Abstract

The objective of the present invention is to provide a transparent display virtual touch apparatus, which can be sophisticatedly operated by using a transparent display portion that can be worn on the face and positioned right in front of an eye of a user, and allows identification of content regardless of the direction the user is facing or the location of the user. The present invention comprises: the transparent display portion, which is can be worn on the face and is positioned in front of the eye of the user; a first image obtaining portion, which is coupled to one side of the transparent display portion, for capturing the position of the eyes of the user; a second image obtaining portion, which is coupled to one side of the transparent display portion, for capturing the body of the user; and a virtual touch processing portion for detecting first space coordinates and second space coordinates, each of which are calculated by using 3D coordinates data from images that are captured by the first image obtaining portion and the second image obtaining portion, respectively, and for calculating contact point coordinate data where a line connecting the first space coordinates and the second space coordinates meets a display surface of the transparent display portion.

Description

technical field [0001] The invention relates to a virtual touch device for a transparent display. The device uses images captured by a camera to identify a certain part of the user's body, and calculates the contact point with the transparent display worn on the user's body. To the content displayed in the display contacts, so as to be able to operate the interface of the electronic device or obtain information related to the content. Background technique [0002] The present invention is derived from the comparison of the traditional touch screen technology (without pointer) and the pointer technology of the display (with pointer). Recently, electronic devices equipped with touch screens such as smartphones are widely used. Compared with existing electronic devices such as computers and smart TVs that are operated by a mouse, the advantage of touch screen technology is that it does not need to display a pointer on the display. That is, the user does not need to move the p...

Problems solved by technology

[0003] However, although touch screen technology has the above-mentioned convenience, its disadvantage is that it cannot be used remotely because the user must directly touch the display surface (to operate).

[0005] However, the problem with this conventional technology is that it is not easy to perform more accurate operations because the display used to operate the electronic device or obtain information is located far away from the user.

[0006] Moreover, it is inconvenient that in order to perform a virtual touch for operating an electronic device or obtaining information, the user's line of sight must be fixed along the direction of the display before the virtual touch operation can be performed.

[0007] In addition, if the electronic device does not have a display, the operation itself cannot be completed
