> 中文摘要: 在触控交互中,缺少触觉反馈会造成用户操作水平的降低和用户体验的下降.前人研究对在触控交互中增加触觉反馈这一方法进行了探索.然而,由于现有触摸屏技术仅能在用户点击屏幕后检测用户手指的位置,触觉反馈也只能在用户点击屏幕之后发挥作用.新的传感技术可以在触摸屏上方的悬浮空间(hover space)内提前检测到手指的位置.利用多对象选择任务(multi-target pointing task)比较了在悬浮空间中增加4种反馈方式对用户操作水平和用户体验的影响.实验结果显示,增加的点击振动反馈受到了用户的普遍青睐.然而,增加的触觉反馈对于用户的操作效率和正确率却没有影响.根据这些结果和前人的研究,提出了在悬浮空间中增加触觉反馈的设计建议.

Abstract:Adding haptic feedback to touch screens is promising in improving users' productivity. However, most touch screens only track user's finger position when the user touches the screen. As a result, haptic feedback is not provided until touch is detected. This paper investigates adding haptic feedback in addition to visual feedback in hover space—the space above the touch screen. Four feedback conditions are compared in a multi-target pointing task. Experimental results show that there is no significant difference between the four feedback conditions as far as task completion speed and accuracy are concerned. The additional haptic feedback neither improves nor deteriorates performance as compared with the visual-only condition no matter it was added in hover space or as a button-click feedback. However, the button-click feedback is most favorable to users. Based on these results and previous literature, this study creats guidelines on how to add haptic feedback in hover space.
