라이다 센서를 활용한 교육용 인터랙티브 콘텐츠 개발

Abstract

Interactive media can expect higher learning efficiency than existing education methods. However, in order to utilize interactive media, various devices and software are required, and these devices are difficult to install and operate and do not perfectly provide necessary functions. Therefore, in this study, we build an interaction environment using Unity and lidar sensors and produce educational contents. A laser-based LiDAR sensor is used as motion recognition equipment. The LiDAR sensor is easy to recognize the user's motion, but it is difficult to process the wide range of noise that the sensor has. To solve this, we limit the recognition range of the sensor to be the same as the screen size, and use the Unity engine's Raycast function to reduce the noise of the LIDAR sensor. As a result, the accuracy of the system is improved and smooth interaction with the user is possible. Currently, the developed interactive contents are installed and operated at the Right Eating Life Experience Center of the Health Promotion Agency of the Seoul Metropolitan Office of Education.
