Abstract

The purpose of the present invention is to develop an input device, which can represent or control various videos and images by recognizing hand gestures on a three-dimensional space and receiving recognition signals. To achieve the above purpose, the input device comprises a cam pen (tentative name) with a camera and a sensor, and a pad (tentative name) with an AR marker and a sensor. Three-dimensional space coordinates can be recognized through communications between the sensor and the AR marker arranged in the cam pen and the pad; effective data and measurements extracted herein are transmitted to a terminal such as a PC through wireless communications; and the transmitted data and measurements are interlocked with various programs built in the terminal or systems and separate content in real time to work thereon. Such a series of processes are realized by various types of input device functions such as functions of representing (displaying) and controlling videos or images in a screen of a terminal.

An infrared sensor, a PCB circuit, a wired / wireless communication, and the like are basically required for the cam pen and the pad to recognize the three-dimensional motion and to extract the data of the spatial coordinates, and the calculation method of the spatial coordinates through the infrared sensor is shown in FIG. The proposed method uses the trigonometric equation as shown in Fig. 3. As shown in Fig. 3, the motion of the user in the three-dimensional space is defined as motion -> recognition -> transfer -> processing -> output phase In order to determine the location through the infrared sensor, the spatial coordinates of the light emitting part of the cam pen and the receiving part of the pad are calculated, and the spatial coordinate value is obtained. Then, it is transmitted to the final output part through a separate process.

The three-dimensional input device, which is a final object of the present invention, is an apparatus that can recognize and process the position (spatial coordinates) in real time through interaction between a camping pen having an infrared sensor light emitting unit and a pad having an infrared sensor receiving unit, And 3D images and images can be expressed or controlled by a simple operation in a 3D space.

FIG. 4 is a summary of the three-dimensional motion recognition and processing procedure of the developed apparatus. When the intended operation of the user is presented within the use range of the first apparatus, the corresponding operation is recognized through the sensor or camera installed in the second apparatus The corresponding operation is transmitted to the system by the third device program, the corresponding value is processed by the fourth sensor or the marker recognition program, and the fifth corresponding value is transmitted through wired / wireless communication.

In order to realize the present invention among the basic systems of the present input device as described above, one light emitting portion of the infrared sensor is installed in the front portion of the cam pen as shown in Figs. 2 to 3, and four infrared sensor receiving portions And the distance between AD and BC, AB and CD in which the infrared sensor is installed is the same, and the triangle AZC and BZD are joint triangles as shown in FIG. 1, and the angle of the vertex B can be measured according to the trigonometric function SIN value.

At this time, the formula for calculating the angle is B ° = sin -1 (BZ / ZV), AD = BC, AB = CD, and Z is the position of the light emitting portion.

Further, it can be calculated as a three-way joint of? AZC and? BZD.
