技术的进步提供了新的人机交互形式。目前的研究检查了一种人机交互形式，增强现实（AR），即受试者在真实的世界工作空间中使用计算机投影的虚拟对象进行训练。运动表现与受试者使用传统人机交互时获得的表现进行了比较，即，带鼠标的个人电脑。患者使用目标导向的手臂运动来玩AR和PC版本的水果忍者视频游戏。这两个版本需要相同的手臂动作来控制游戏，但有不同的认知需求。通过AR，游戏被投影到桌面上，受试者在相同的视觉坐标空间中同时观看游戏和手臂运动。在PC版中，受试者使用相同的手臂动作，但通过抬头看电脑显示器来观看比赛。在18名中风后慢性轻偏瘫患者中，AR游戏与PC游戏相比，游戏得分高21%（p=0.0001），达到时间快19%（p=0.0001），运动变异性低15%（p=0.0068）。AR版本的游戏得分和手臂运动状态之间的相关性更强。AR游戏中的运动表现上级PC游戏中的表现。这一结果部分是由于PC游戏对认知的要求更高，这对一些患者来说是一个问题，但对其他人来说是首选。人机界面的模式影响康复治疗的需求，可以为患者个性化。
Advances in technology are providing new forms of human-computer interaction. The current study examined one form of human-computer interaction, augmented reality (AR), whereby subjects train in the real world workspace with virtual objects projected by the computer. Motor performances were compared with those obtained while subjects used a traditional human-computer interaction, i.e., a personal computer (PC) with a mouse. Patients used goal-directed arm movements to play AR and PC versions of the Fruit Ninja video game. The two versions required the same arm movements to control the game but had different cognitive demands. With AR, the game was projected onto the desktop, where subjects viewed the game plus their arm movements simultaneously, in the same visual coordinate space. In the PC version, subjects used the same arm movements but viewed the game by looking up at a computer monitor. Among 18 patients with chronic hemiparesis after stroke, the AR game was associated with 21% higher game scores (p=0.0001), 19% faster reaching times (p=0.0001), and 15% less movement variability (p=0.0068), as compared to the PC game. Correlations between game score and arm motor status were stronger with the AR version. Motor performances during the AR game were superior to those during the PC game. This result is due in part to the greater cognitive demands imposed by the PC game, a feature problematic for some patients but preferred for others. Mode of human-computer interface influences rehabilitation therapy demands and can be individualized for patients.
