本文介绍了我们为改善虚拟环境中的用户交互而结合视觉和振动触觉提示所做的工作的结果。使用定制设计的控制系统，可以独立控制大量低成本振动装置的强度。我们当前的任务是确定提供这种类型的线索的参数和设计空间，以支持有效的HCI。在一个视觉搜索任务中，研究人员比较了用户在三个层次的视觉线索和四个层次的振动触觉线索类型上的表现，试图缩小从随机显示的字母中定位字母的视觉搜索范围。我们的结果证实了其他人的工作，表明用户在给予视觉提示时表现得更快，并且在没有视觉提示的情况下，振动触觉提示显着提高了表现。我们还发现，振动触觉线索的波形似乎对表现没有影响。
This paper presents results from work we have done into the combination of visual and vibrotactile cues for improving user interaction in virtual environments. Using a custom-designed control system, the intensity of a large number of low-cost vibrational devices can be independently controlled. Our current task is to determine the parameters and design-space for providing this type of cueing to support effective HCI. In a visual search task, user performance was compared over three levels of visual cues and four levels of vibrotactile cue types, in an attempt to narrow the visual search field for locating a letter from a random display of letters. Our results confirm the work of others, showing that users perform significantly faster when given visual cues, and that in the absence of visual cues, vibrotactile cues significantly improve performance. We also found that the waveform of the vibrotactile cue does not seem to make a difference in performance.
