Improving the experiences of people in multi-user computer assisted collaborative activities or training to the extent that their interactions with each other and with their virtual environments are almost lifelike will requires much better haptic (force and touch) feedback technology than is currently available. In particular, little is available to provide human-human and human-world touch feedback when groups of users are moving freely, rather than seated at desktop displays. Compact vibration feedback devices could be used, notwithstanding that the user's ability while in motion to perceive high-frequency vibration is likely to suffer. An alternative method of activating the touch sensors in human skin is to apply distributed cutaneous stimulants, or skin stretch, but little is known about its effects on the body, or if it can be used as a body-mounted haptic display. The PI's goal in this project is to explore such issues. In particular, he will investigate the effects of both distributed skin-stretch and vibration feedback applied by means of light-weight, low-power "tactors" that can be mounted/worn at various locations on a person's body. The PI will conduct experiments to quantify the effects of skin-stretch in comparison to vibration feedback for both sedentary and rapidly moving users, and will conduct preliminary investigations of the effects of body worn tactors in a physical rehabilitation environment, in the hope of improving motion training exercises which patients often require when recovering from injuries or strokes. The results of these experiments will provide a first indication of how best to utilize skin-stretch and vibration displays in virtual environments and in human-human interactions, and will also guide further tactor development.Broader Impacts: In comparison to vision and sound, haptic feedback is an underdeveloped channel. New technologies such as those the PI will investigate in this project promise to revolutionize human-computer interaction and computer-mediated human-human interaction in a host of diverse domains, not the least of which are timely applications such as training exercises for emergency personnel and collaborative efforts among geographically distributed teams to develop emergency procedures.

改善人们在多用户计算机辅助协作活动或培训中的体验，使其彼此之间以及与虚拟环境的交互几乎栩栩如生，这将需要比目前可用的更好的触觉（力和触摸）反馈技术。 特别是，当用户组自由移动而不是坐在桌面显示器前时，几乎无法提供人与人以及人与世界的触摸反馈。 可以使用紧凑的振动反馈设备，尽管用户在运动时感知高频振动的能力可能会受到影响。 激活人体皮肤中的触摸传感器的另一种方法是应用分布式皮肤刺激剂或皮肤拉伸，但人们对其对身体的影响知之甚少，或者是否可以将其用作身体安装的触觉显示器。 PI 在这个项目中的目标就是探索这些问题。 特别是，他将研究分布式皮肤拉伸和振动反馈的影响，这些反馈是通过可以安装/佩戴在人体不同位置的轻质、低功率“触觉器”施加的。 PI 将进行实验，以量化久坐和快速移动用户的皮肤拉伸与振动反馈的影响，并将对身体佩戴的触觉器在物理康复环境中的影响进行初步调查，以期改善运动患者在从受伤或中风中恢复时经常需要的训练练习。 这些实验的结果将首次表明如何在虚拟环境和人与人的交互中最好地利用皮肤拉伸和振动显示，并将指导进一步的触觉器开发。 更广泛的影响：与视觉和声音相比，触觉反馈是一个不发达的渠道。 PI 将在该项目中研究的新技术有望在许多不同领域彻底改变人机交互和计算机介导的人机交互，其中最重要的是及时应用，例如应急人员的培训演习和地理分布的团队之间协作努力制定应急程序。
