Abstract

ReFlex is a flexible smartphone with bend input and active haptic feedback. ReFlex's features allow the introduction of sensations such as friction or resistance. We report results from an experiment using ReFlex in a targeting task, as well as initial users' reactions to the prototype. We explore both absolute and relative tactile haptic feedback, paired with two types of bend input mappings: position-control and rate-control. We observed that position-controlled cursors paired well with relative bend feedback, while rate-controlled cursors paired well with absolute bend feedback to indicate targets. We also explored an eyes-free condition. Results suggest that while eyes-free, haptic feedback conditions were more error-prone than visual-only conditions, the size of the error was relatively small, and users were able to complete the task in all cases. We present two application scenarios that take advantage of the unique input and output modalities of ReFlex and discuss its potential for within document navigation.

反射:一个灵活的智能手机与主动触觉反馈弯曲输入
ReFlex是一款灵活的智能手机,具有弯曲输入和主动触觉反馈。反射的特点允许引入摩擦或阻力等感觉。我们报告了在目标任务中使用ReFlex的实验结果,以及最初用户对原型的反应。我们探索了绝对触觉和相对触觉反馈,并结合了两种类型的弯曲输入映射:位置控制和速率控制。我们观察到位置控制游标与相对弯曲反馈匹配良好,而速率控制游标与绝对弯曲反馈匹配良好,以指示目标。我们还探索了一种不需要眼睛的情况。结果表明,虽然没有眼睛的情况下,触觉反馈比只有视觉反馈的情况更容易出错,但错误的大小相对较小,用户在所有情况下都能完成任务。我们提出了两种利用ReFlex独特输入和输出模式的应用场景,并讨论了它在文档导航中的潜力。
