Field of the Invention The present invention relates to an interface device capable of generating a control command according to the shape of a hand, and more particularly, to an interface device capable of generating various control commands To a grip type input interface device and a method thereof.

Due to the development of computer technology, it has become necessary to interact with a computer that performs high-speed data processing. Examples of such interaction means include a mouse and a keyboard.

Currently, the most widely used keyboard is used as a means of inputting text control commands to a computer, and the mouse is used for intuitive movement and control commands input on the interface screen such as fast positioning, drag and drop.

To this end, the keyboard is configured to have a key arrangement in which predetermined characters are arranged, and the mouse is configured to include a left click button, a right click button, a scroll ball, a pointer movement ball, or an optical device so as to perform movement, selection and execution, .

However, according to the development of computer technology, game technologies and virtual reality technologies which require input of complicated control commands have also been developed, so that there are many restrictions on the input of control commands in the conventional keyboard and mouse.

In order to overcome the input restriction of the keyboard and the mouse, Korean Patent Laid-Open Publication No. 10-2005-0015235 discloses a method of attaching a contact switch using conductive silicone or conductive fibers to the tip of each thumb (12) Discloses a vibrating glove type game controller that enables various inputs to be performed by generating an electric signal generated when the end of a finger is grounded to contact with twelve other nodes.

Korean Patent Laid-Open Publication No. 10-2010-0089646 discloses a finger grip which is composed of a base part 120 and a thumb part composed of a touch part 130 so that two fingers (thumb, (Finger ring) glove.

Korean Patent Publication No. 10-2014-0128305 also discloses a housing 100 having a sensing unit having at least one control button 120, 130, 140 capable of generating a control signal for an associated computerized system, Based interaction system and method that enables to perform functions such as directional movement, button click, drag-drop, etc. by pressing buttons, including a gesture-based interaction system.

Korean Patent Laid-Open Publication No. 2002-0096807 discloses a glove type data input device.

Shaped image input means 200 having an image acquisition means, an input means, a front button 210, a left button 220, a right button 230 and a top button 240, ) For inputting a control command by pressing the input means (200) and using the image acquired by the image acquisition means (100).

However, the above-described gesture recognition apparatus of the related art has a problem in that a restriction is imposed on a control command input due to restriction of input combinations when a plurality of apparatuses are required or when a minimum number of apparatuses are used.

In the case of the conventional motion capture, it is very intuitive, but the recognition is slow and error-prone. In the case of the console controller, the response speed is fast but the intuition is very low. Therefore, intuitive input, fast response speed, And the like can not be satisfied.
