以往的研究表明,空间记忆和语义辅助可以帮助用户学习和记忆手势命令。因此,有人提议利用机体作为支持,将这两个方面联合收割机结合起来,但尚未有正式评价报告。在本文中,我们比较了身体上的交互技术(BodyLoci)在虚拟现实环境中的空中标记菜单。我们考虑三个层次的语义援助:没有援助,故事制作,故事制作与背景图像。我们的研究结果显示,当使用故事制作时,特别是对于标记菜单(保留率提高28.5%),有了重要的改进。这两种技术在没有语义辅助的情况下表现相似,但使用标记菜单时,它们的表现优于BodyLoci(保留率提高了17.3%)。虽然我们的研究没有显示使用身体支持的好处,但它表明,引导用户利用简单的学习技巧,如讲故事,可以大大提高回忆,从而更容易掌握手势技巧。我们还分析了参与者创建助记符所使用的策略,为未来的工作提供指导。
Previous studies have shown that spatial memory and semantic aids can help users learn and remember gestural commands. Using the body as a support to combine both dimensions has therefore been proposed, but no formal evaluations have yet been reported. In this paper, we compare an on-body interaction technique (BodyLoci) to mid-air Marking menus in a virtual reality context. We consider three levels of semantic aids: no aid, story-making, and story-making with background images. Our results show important improvement when story-making is used, especially for Marking menus (28.5% better retention). Both techniques performed similarly without semantic aids, but Marking menus outperformed BodyLoci when using them (17.3% better retention). While our study does not show a benefit in using body support, it suggests that inducing users to leverage simple learning techniques, such as story-making, can substantially improve recall, and thus make it easier to master gestural techniques. We also analyze the strategies used by the participants for creating mnemonics to provide guidelines for future work.
