Description

METHOD AND APPARATUS FOR DISTINGUISHING FIVE FINGERS IN ELECTRONIC DEVICE INCLUDING TOUCH SCREEN}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to electronic devices and, more particularly, to methods and devices for distinguishing five fingers in an electronic device including a touch screen.

A touch screen is a touch display device in which a user inputs a command to an electronic device using a hand or a special device on a screen. In the past, the use of touch screens was limited to industrial products, but the share of touch screens is increasing in mobile devices. In addition, active research on touch screen solutions for medium and large display devices has been actively conducted due to the trend toward larger touch screens. In other words, in order to perform a function of enlarging and reducing an image viewed by two fingers, research on multi-touch technology is being conducted. Multi-touch can recognize three or more independent points.

Meanwhile, it is possible to determine how many points are touched on the touch screen and execute a command in a corresponding combination. For example, a thumb is connected with a first command, an index finger is connected with a second command, a middle finger is connected with a third command, a ring finger is connected with a fourth command, and the holding finger is a fifth command. When connected, the touch combination of five fingers can be used as an input means for executing a command.

Background Art Conventionally, a finger is divided by a multi-touch, and the touch area and x / y coordinates, a camera, a fingerprint, and the like are divided.

However, the method of classifying fingers using the touch area is difficult to classify the fingers accurately if the touch screen does not touch the user's palm or the thumb is elliptically wide. In this case, when the hand is rotated and touched, it is difficult to accurately distinguish the fingers. In addition, in the method of classifying a finger using a camera and a fingerprint, a separate camera and a fingerprint recognition module should be added.

Accordingly, there is a need for a method and apparatus for accurately recognizing a touch of five fingers without using a separate camera and a fingerprint recognition module in an electronic device including a touch screen.

An object of the present invention is to provide a method and an apparatus for distinguishing five fingers by using a center point of a circle passing through a touch point of five fingers and a center angle between each touch point in an electronic device including a touch screen.

According to a second aspect of the present invention for achieving the above object, a method for distinguishing five fingers in an electronic device including a touch screen, the method comprising: detecting a touch point of five fingers, between the touch points of the five fingers Using distance, the process includes mapping five fingers to thumb, index finger, middle finger, ring finger, and hand.

According to a third aspect of the present invention for achieving the above objects, a touch screen; One or more processors; Memory; And at least one program stored in the memory and configured to be executed by the at least one processor, wherein the program detects a touch point of five fingers and at least one of the touch points of the five fingers. It includes commands to map five fingers to thumb, index finger, middle finger, ring finger, and hand with the center of the circle passing through the touch point.

According to a fourth aspect of the present invention for achieving the above objects, a touch screen; One or more processors; Memory; And at least one program stored in the memory and configured to be executed by the at least one processor, wherein the program detects a touch point of five fingers and uses a distance between the touch points of the five fingers. To map the five fingers to the thumb, index finger, middle finger, ring finger, and possession.

As described above, by distinguishing the five fingers by using the center point of the circle passing through the touch points of the five fingers and the center angle between each touch point or the distance between the touch points of the five fingers, it is effective regardless of the touch area and x / y coordinates. Five fingers can be recognized. In addition, five fingers may be distinguished without using a separate camera and a fingerprint recognition module.

In addition, in a relatively large multi-touch device such as a tablet capable of touching all five fingers, the first five fingers may be recognized, and then various commands may be executed by a touch combination of each finger.

The thumb, index finger, middle finger, ring finger, and possession are determined clockwise in the remaining arcs except for the region having the largest central angle (see FIG. 6). , If it is determined by the left hand, the thumb, the index finger, middle finger, ring finger, and possession in the counterclockwise direction in the remaining arcs except for the region having the largest center angle are determined (see FIG. 5).

According to the fourth embodiment of the present invention, when the user touches the touch screen with the five fingers of the left hand, the processor 1300 detects the touch of the five fingers of the left hand on the touch screen, and the reference touch among the five touch points. Determine a point, calculate the distance between the reference touch point and the remaining four touch points, determine the thumb and the thumb that are the furthest distance from the reference touch point, respectively, and based on the determined thumb and possession, counterclockwise Direction, middle finger, and ring finger in the direction (see Fig. 11 (a) below).

According to the fifth embodiment of the present invention, when the user touches the touch screen with five fingers of the right hand, the processor 1300 detects the touch of five fingers of the right hand on the touch screen, and among the five touch points, the reference touch. Determine the point, calculate the distance between the reference touch point and the remaining four touch points, determine the touch point that is the furthest distance from the reference touch point, respectively, as the thumb and possession, and clockwise relative to the determined thumb and possession. Detection, middle finger, ring finger (see Figure 11 (b) below).

According to the sixth embodiment of the present invention, when the user touches the touch screen with five fingers, the processor 1300 detects the touch of five fingers on the touch screen, calculates the distance between five touch points, and calculates the distance. The first touch point and the second touch point (hereinafter referred to as first touch point and second touch point) are farthest apart from the thumb, and the first distance and the first distance between the first touch point and the third touch point adjacent to the first touch point. Comparing the second distance between the second touch point and the fourth touch point adjacent to the second touch point, when the first distance is greater than the second distance, the first touch point becomes the thumb (the second touch point is held). In addition, when the first touch point is on the left and the second touch point is on the right, it is judged by the right hand, while when the first touch point is on the right and the second touch point is on the left, it is judged by the left hand. , The first distance is the second Less than Lee, the first touch point is held (the second touch point is the thumb), and when the second touch point is on the left and the first touch point is on the right, it is judged by the right hand, while the second touch point is When it is on the right side and the first touch point is on the left side, it is judged by the left hand, and when it is judged by the right hand, it is divided into the index finger, middle finger, and ring finger in the clockwise direction based on the determined thumb and the hand (see FIG. 11 (b)). ), When it is determined as the left hand, it is divided into the index finger, middle finger, and ring finger in the counterclockwise direction based on the determined thumb and the hand (see FIG. 11 (a)).

According to another implementation, the processor 1300 divides two touch points of the farthest distance (the first distance) among the distances between the touch points into the thumb and the thumb, and the second of the second farthest distances (the second distance). The touch points can be used to distinguish thumb, index finger, middle finger, ring finger, and hand in the clockwise or counterclockwise direction. For example, the overlapping touch points among the touch points forming the first distance and the second distance become the thumb (see FIGS. 12A and 12B).
