Creation of the swimming instruction support system using underwater video

本研究的目的是：(1)建立用水下视频图像图形化地显示游泳过程中的阻力的系统。(2)使用该系统进行游泳技术掌握效果的指令检验。系统硬件配置：该系统通过视频效应器将卷取系统的PC输出和水下游泳图像合成，并将结果记录在视频上。软件开发：编制了I/O数据和图形数据的实时绘制等软件。设计了计时器的精度、显示方法等。利用该系统指导游泳技术的掌握效果：该系统应用于游泳教学现场。这个问题是通过使水下图像和PC图形相对应来发现的。它检查了练习后是否会再次拍摄视频，它会有所改善。因此，技能的提高通过在短时间内具体地捕捉问题，在练习后听说了态度控制。

Purposes of this investigation were as follows ;(1) Creation of the system which displays graphically the drag during swimming with the underwater video-image.(2) Examination of the mastery effect of the swimming skill by instruction using this system.Systems configuration of hardware : The system which compounds the PC output of Reel-up system and underwater swimming image by the video effector, and records a result on videotape.Development of software : Software, such as I/O data and real-time drawing of graphical data, was created. The accuracy of the timer and display method etc was devised.The mastery effect of the swimming skill by instruction using this system : This system was employed in the swimming instruction spot. The problem was discovered by making an underwater image and the PC graph correspond. It checked whether after practice, a video would be taken again and it will have improved. Consequently, the improvement in skill heard about attitude control after practice by catching a problem concretely over a short period of time.
