Gesture cognitive device and method for recognizing gesture

The present invention relates to a motion recognition device and a motion recognition method, and more particularly, a three-dimensional motion recognition device and a motion recognition method for remotely controlling various electronic devices by recognizing the position of the finger and the gesture (Gesture) of the finger. It is about.

Recently, as the digital media are widely used, the type and number of electronic terminal devices have increased rapidly, and various input devices for controlling respective devices have been newly introduced and used.

In the case of general household appliances such as TVs, video players, DVD players and audio, a remote controller (hereinafter referred to as a "remote control") is used as a general control means. However, as the type and number of the home appliances increase, the number of remote controllers for controlling the home appliances increases in proportion to the increase in the number of home appliances. The hassle of using a remote control increases.

On the other hand, computer-based host devices, such as PCs, laptop computers, and PDAs, are increasingly including home appliances and media players as their role in home networks and media players have increased. Thanks to the support, it is possible to perform the same type of operation as a home appliance using a remote control.

Of course, in the case of a computer-based host device, devices such as a keyboard, a mouse, a trackball, a tablet, and a stylus, which are conventionally used as input methods, are steadily used, and in the case of a portable device, a tablet-type input due to the size and portability of the device The method is mainly used.

However, while the control area of various information appliances connected by wired and wireless networks is gradually being broken down, the control means of such devices, that is, the human input means, are still limited to the level of a remote controller, a keyboard, and a mouse.

One of the conventional techniques proposed to remedy this situation in general household appliances is a universal remote control. The universal remote controller may be configured by collecting a plurality of operations commonly used by general household appliances that can be controlled through the remote controller as a single device, and then selecting a device to be controlled and selecting a button indicating a corresponding operation. . However, it is difficult to miniaturize the input device in the form of a remote control due to a physical input method in the form of a button, and thus there is a limitation in using it as a portable input device for controlling the portable device.

Conventional techniques proposed to improve the situation in computer-based host devices include a combination of a three-axis angular velocity sensor, a three-axis acceleration sensor, and a three-axis speed sensor to detect motion in three-dimensional space. There are pen-type pointing devices. The devices include various sensors and the like, and are wirelessly connected to the computer device, and transmit the change in the angular velocity due to the tilting and movement of the pointing device to the computer to move the computer's mouse pointer or extract a trace for handwriting recognition. However, the method is also not suitable as a portable input device because it is difficult to miniaturize and cannot be worn because it is necessary to distinguish the beginning and the end of the movement by using a button as in a conventional mouse.

Another prior art is a pen-type input device using a three-axis acceleration sensor and a three-dimensional optical recognition device. The device measures the contact with a predetermined plane (eg, a table) and its angle by using a 3D optical recognition device, and reflects the measured attitude information of the device to acceleration information generated by the movement of the pen. Extract the trajectory by. Therefore, the device can be used for handwriting recognition-based applications. However, there is a limitation that miniaturization is difficult because the device must also have two kinds of sensors and the like, and also there is always a need for an arbitrary plane to which the pen tip can be physically contacted.

As another prior art, there is a small ring input device using a two-axis acceleration sensor. The device analyzes the user's movement trajectory by detecting acceleration due to finger movement on a predetermined plane. That is, the micro-collision signal generated when the finger touches the predetermined contact surface and the rising signal generated when leaving the contact surface are detected by the 2-axis acceleration sensor, and the finger movement trajectory is extracted by double integration of the acceleration information between the sections. The extracted information is used as pointing information of a computer. However, the above method has a limitation that it can be used only when there is a predetermined plane such as a table that can be physically contacted but has a structure that can be worn compactly.

Therefore, the present invention can integrally manage all the electronic devices (TV, Audio, PC, Smart phone, etc) capable of wireless communication without a control device (Remote control, Touch pad, Key pad, Mouse), in particular the display screen In the case of touching the screen, it is possible to prevent the screen from being contaminated, it is difficult to operate from a long distance, and only the flat operation can compensate for the disadvantage of not using various hand motions for controlling the device.

Preferably, the motion recognition unit 10 and the magnet unit 20 are made compact so that they can be mounted on the end of the user's finger or nail, so as to recognize the movement of the hand and even the minute movement of the finger. . In particular, the operation recognition unit is formed of a synthetic resin material having an elastic force to protect a plurality of sensors provided inside, for example, the acceleration sensor 11a, the angular velocity sensor 11b, the magnetic force sensor 11c from an external impact. desirable.

The motion recognition unit 10 further includes a mounting means for easy mounting on the end of the finger.

The mounting means may be embodied as, for example, a ring-shaped band 2.

An adhesive may be applied to the bottom surface of the operation recognition unit 10 to be attached to the nail like a sticker. Therefore, the motion recognition unit 10 may be used in any method as long as it can be mounted on the end of the finger or the fingernail and can be freely mounted by the user without being disturbed by the movement of the finger.

On the other hand, the motion recognition unit 10 is mounted on the end of the finger to sample the data of the acceleration, angular velocity and magnetic change in the x, y, z direction for the movement of the finger, and then sample the previously recognized motion and comparison judgment As a means for recognizing a current operation, as shown in FIG. 1, the sensor unit 11 includes a sensor unit 11, a memory unit 12, a control unit 13, a wireless communication unit 14, and a power supply unit 15.

The acceleration sensor 11a and the angular velocity sensor 11b use two sensors to indicate the movement path of the finger. First, after the start point is taken, the direction is obtained by the angular velocity sensor 11b, and the acceleration sensor 11a is obtained. ) To get the acceleration value and integrate it twice to find the distance so that the current position can be recognized in the distance and direction from the starting point. In addition, the acceleration sensor 11a may have a three-axis output value, and the front and rear directions forming an angle of 90 degrees with the left and right directions and the left and right directions around the operator, and the vertical direction forming an angle of 90 degrees with the left and right directions and the front and rear directions, respectively. Since six directions of three axes, etc., are the object of motion recognition, the acceleration value and the inclination value are recognized at the same time so that it can be reflected in the operation of the game according to the operator's operation behavior.

When the same effect as the operation of the mouse is produced by using the acceleration sensor 11a and the angular velocity sensor 11b, the controller 13 repeatedly controls a speed value proportional to the degree to which the user moves or tilts the acceleration sensor 11a. By calculating a predetermined code value to be stored in the memory unit 13 to be described later, after the user attaches the motion recognition device (1) to the finger, if you move the finger left or right or up and down, Depending on whether or not the calculated code value matches, the cursor in the computer screen can be moved left and right or up and down like a mouse operation.
