Abstract: A control method for allowing a user to specify an electronic device and switch it to a speech recognition mode is provided. With the optimum control method and the electronic device utilizing the method, a voice command may be transmitted to the electronic device more quickly and effectively regardless of the circumstances, and the electronic device may be specified through gesture recognition to enable transmission of the voice command, so that the voice command may be effectively executed without needing a user to learn or memorize a name or the like of the electronic device in advance for speech recognition. Further, it is possible to more accurately recognize a gesture that is a preliminary step for transmitting a voice command to the electronic device, thereby improving the recognition rate and preventing malfunction.

Abstract: Disclosed are a method and an apparatus for accurately detecting a gesture from a user's motion using a user-based spatial coordinate system. A method for detecting a gesture in a user-based spatial coordinate system comprises the steps of: setting a user-based spatial coordinate system using a first body coordinate corresponding to a first body part of the user as a starting point; analyzing the motion vector state of a second body coordinate corresponding to a second body part of the user in the user-based spatial coordinate system over time; and detecting the user's gesture on the basis of a change in the motion vector state.

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.
