The infrared point position recognition system according to the related art recognizes the coordinates of the infrared point on the screen in order to obtain coordinates on the screen using the infrared ray input device and calculates the position and the firing point of the infrared ray input device by the user .

More specifically, in accordance with the operation of the infrared ray input apparatus including the infrared ray point function, the calculation apparatus determines whether an infrared ray point (or pattern) blinking at a position intersecting on the screen in the direction in which the infrared ray input apparatus looks in real- And then calculating the position of the infrared point.

In this case, the infrared camera has a built-in external form separate from the infrared input device and a built-in form included in the infrared input device, but the overall operation of the system is very small.

In the case of processing data operation on the infrared point position recognition system, as shown in FIG. 1, the infrared point (pattern) sensing process S1, the coordinate derivation and user analysis process S2, and the user and coordinate matching process S3 It is subjected to a three-step calculation process. That is, the infrared point position recognition system detects and analyzes the infrared point generated at the intersection of the direction of the infrared ray input device and the screen, and identifies the coordinates and the user of the infrared ray point viewed by the user's infrared ray input device. Finally, the infrared point position recognition system can be applied to various calculation processes based on the user identification value of the coordinates by matching the coordinates with the user.

However, the existing system has a problem that it is impossible to process the final data by calculating the final data through three steps of user identification, coordinate recognition, user and coordinate matching, .

In other words, the infrared point position recognition system has a disadvantage in that it can not identify who is the detected infrared point when a plurality of people participate, and in order to solve this problem, a method of mainly outputting a specific pattern or color is used However, there is a limit in addition that arithmetic processing according to user identification occurs.

Accordingly, in the related art, it is required to reduce the number of steps required for the entire operation so that the time required for user identification is greatly reduced, so that a technology for enabling system operation even when using a multi-infrared input device is required.
