体感交互技术在教育中的应用现状述评

Motion Sensing Technology in Education

体感技术是人机交互历史上的一次革命,它以躯体动作、声音等自然语言来操纵多媒体设备,提供了革命性的体验。目前,体感技术研究集中在感应精度与深度方面,在教育应用领域也有一些前沿探索和实验。该技术自体感游戏开始之际便进入了大众视野,在实现技术上可分为惯性感测、光学感测以及惯性及光学联合感测三类,微软的Kinect采用了光学测感和声学感知技术。在教育应用方面,体感游戏开始进入课堂,就取得了较好的影响。它在语言、数学、科学、物理、特殊教育等不同学科领域内均有应用,通过三个典型案例详细讨论了其具体的教学步骤。体感技术在教学中作为教/学工具、教学内容和教学环境,可用于情境化学习、个别化学习以及游戏化学习三类教学形式,并根据不同用途具有多个整合关键点。总之,体感技术应用在教育中具有体验优、多感官、以学生为中心和支持合作学习的优势,但现阶段在部署、教学法和评价上还存在一些问题。

Motion sensing technology, a revolution in the history of human-computer interaction, can manipulate multimedia equipments by means of body movements, sounds and other natural languages, which is a revolutionary experience to us. Now, the researches on motion sensing technology focus on sensing accuracy and depth, and its application in education. This technology has attracted many people’s attention with the development of motion sensing game, which can be divided into inertial sensor, optical sensor and combination of inertial sensor and optical sensor. Kinect of Microsoft adopted inertial sensor technology and acoustic sensor technology. Motion sensing game has made some achievements when it is applied into many fields such as language, mathematics, science, physics and special education. In the paper, three specific examples with detailed teaching process are analyzed. When motion sensing technology is applied into education, it has some characteristics of teaching/learning tools, teaching content and teaching environment, which can be used in situated learning, personalized learning and game learning. Motion sensing technology has some advantages of good experience, multi sensory, student-centered teaching and cooperative learning when applied into education, while some problems arise from teaching plan, teaching methods and assessment.
