VIRTUAL TOUCH DEVICE WITHOUT POINTER
First Claim
1. A virtual touch device for remotely controlling electronic equipment having a display surface, and more particularly, to a virtual touch device for exactly controlling electronic equipment remotely without displaying a pointer on a display surface of the electronic equipment, 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.

Abstract
Provided is a virtual touch device for remotely controlling electronic equipment having a display surface. The virtual touch apparatus include an image acquisition unit, a spatial coordinate calculation unit, a touch location calculation unit, and a virtual touch processing unit. The image acquisition unit includes two image sensors disposed at different locations and photographs a user'"'"'s body at the front of the display surface. The spatial coordinate calculation unit calculates three-dimensional coordinate data of the user'"'"'s body using an image from the image acquisition unit. The touch location calculation unit calculates 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.
