Currently, virtual applications for physical exercises are highly appreciated as rehabilitation instruments. This article presents a middleware called "MoKey" (Motion Keyboard), which converts standard off-the-shelf software into exergames (exercise games). A configurable set of gestures, captured by a motion capture camera, is translated into the key strokes required by the chosen software. The present study assesses the tool regarding usability and viability on a heterogeneous group of 11 participants, aged 5 to 51, with moderate to severe disabilities, and mostly bound to a wheelchair. In comparison with FAAST (The Flexible Action and Articulated Skeleton Toolkit), MoKey achieved better results in terms of ease of use and computational load. The viability as an exergame creator tool was proven with help of four applications (PowerPoint®, e-book reader, Skype®, and Tetris). Success rates of up to 91% have been achieved, subjective perception was rated with 4.5 points (from 0-5). The middleware provides increased motivation due to the use of favorite software and the advantage of exploiting it for exercise. Used together with communication software or online games, social inclusion can be stimulated. The therapists can employ the tool to monitor the correctness and progress of the exercises.
目前，虚拟应用程序在物理运动康复中受到高度赞赏。本文提出了一种名为“MoKey”（运动键盘）的中间件，它可以将标准的现成软件转换为运动游戏（exercise games）。一组可配置的手势，由运动捕捉摄像机捕捉，被转换成所选软件所需的按键。本研究在一个由 11 名年龄在 5 到 51 岁之间的参与者组成的异质群体中评估了该工具的可用性和可行性，这些参与者都有中度到重度残疾，并且大多都坐在轮椅上。与 FAAST（灵活动作和铰接骨骼工具包）相比，MoKey 在易用性和计算负载方面取得了更好的效果。通过四个应用程序（PowerPoint ®、电子书阅读器、Skype ®和俄罗斯方块）证明了其作为运动游戏创建工具的可行性。成功率高达 91%，主观感知评分为 4.5 分（0-5 分）。由于使用了喜欢的软件，中间件提供了更高的动力，并且可以利用它进行锻炼。与通信软件或在线游戏一起使用，可以促进社会包容。治疗师可以使用该工具来监测练习的正确性和进度。
