UltraHaptics
注 2
也允许你在空中感受虚拟对象。与 AIREAL 通过在
用户面上吹小气环来模拟触感不同，UltraHaptics 的核心技术是高频
超声波。作为 GHOST 项目的一部分，布里斯托大学的计算机科学家
在 2013 年开发了 UltraHaptics，并成立了一家创业公司以将此技术
产品化。
UltraHaptics 利用红外传感器来跟踪用户手指在三维空间中的精确位
置，使超声波能够准确地指向用户的手，并产生相应的触感。该公
司设想了一系列技术应用，包括与 VR 游戏中的移动物体（可扩展到
AR）进行交互，以及汽车仪表板的空中控制。在家庭环境中，该技术
可以在空中控制各种厨房用具，以避免在烹饪时弄脏双手。
该公司还在研究安全解决方案，包括与捷豹路虎合作开发其信息娱乐
智能系统的空中触摸屏幕。该系统可以最大限度地减少驾驶员的眼睛
和手停留在屏幕上的时间，以减少司机分心的情况发生。在交互区域
内，UltraHaptics 解决方案能够对驾驶员的手进行定位和跟踪，系统会
利用物理感觉来指示相应的链接。用户可以感觉到开关和按钮，在空
中控制它们，并获得反馈以确认相应操作已经成功完成，而所有这些
操作都不需要查看显示屏。
触觉通信
除了模拟控件或虚拟对象的触感，UltraHaptics 之类的交互系统还为我
们的交互提供了其他的可能。苏塞克斯大学信息学系的科学家和讲师
Marianna Obrist 正在使用 UltraHaptics 来探索情感的沟通。Obrist 写道：
触摸是人类之间交流的强大手段。对交互式系统的设计需求 ...
