Provided is a virtual touch device for remotely controlling electronic equipment having a display surface, and more particularly, without displaying a pointer on the display surface; comprising an image acquisition unit comprising two image sensors disposed at different locations and photographing a user's body at the front of the display surface; a spatial coordinate calculation unit calculating three-dimensional coordinate data of the user's body using an image from the image acquisition unit; a touch location calculation unit calculating a contact point coordinate where a straight line connecting between a first spatial coordinate and a second spatial coordinate meets the display surface using the first and second spatial coordinates received from the spatial coordinate calculation unit; and a virtual touch processing unit creating a command code for performing an operation corresponding to the contact coordinate received from the touch location calculation unit and inputting the command code into a main controller of the electronic equipment. Therefore, a virtual touch device according to an embodiment of the present invention enables accurate and prompt control of electronic equipment without using a pointer on a display surface. |
