Multi-touch tables, such as Microsoft Surface, are now widely available. Users can walk-up and use these systems in hotel lobbies and other public settings with very little instruction and with no need to wear or hold intrusive sensors with their hands or body. The ability to 'walk-up and use' with unadorned hands and fingers removes the barrier between human and technology, encouraging spontaneous use. One of the primary disadvantages of current interactive surfaces is that users can touch objects, but they are unable to feel them. There are a plethora of applications where it is beneficial for the user to have their touches augmented with 'feel-based' haptic feedback. For example, medical applications, virtual training, and modelling applications require precise control from the user-haptic feedback can aid the user in effectively performing these tasks. These applications demonstrate the benefit of augmenting haptic feedback with visual feedback in an interactive application. Often, the visual space has been disconnected from the force-feedback, requiring a prolonged training period for the user to become accustomed to moving a digital object and watching the interactions a small distance away on a monitor. In this proposal we will investigate the use of ultrasound transducers to provide 'feelable' feedback through air. The skin on a human hand can feel the ultrasonic pressure wave produced by a carefully calibrated series of transducers, in much the same manner that is apparent from loud sub-woofers on a stereo system. Ultrasound waves are outside the human's range of hearing and so provide silent, through-air haptic feedback. We will use this technology to provide multi-point haptic feedback on the surface of a multi-touch horizontal surface.The team consists of Dr. Sriram Subramanian, Dr. Mark Marshall and Dr. Jason Alexander from the computer science departments and Prof. Bruce Drinkwater from the Mechanical Engineering department of the University of Bristol and Prof. Stephen Brewster from the Computer Science department of the University of Glasgow. The team is internationally recognised for its research in Human-Computer Interaction (HCI), novel integration of hardware for HCI, and Ultrasonic sensors. Microsoft research (Cambridge) and XMOS will serve as project partners and offer valuable resources and support for the project.

多点触摸桌，如微软Surface，现在已经广泛使用。用户可以在酒店大堂和其他公共场所使用这些系统，只需很少的指导，并且不需要用手或身体佩戴或持有侵入式传感器。用不加装饰的手和手指“走上去使用”的能力消除了人类和技术之间的障碍，鼓励自发使用。当前交互式表面的主要缺点之一是用户可以触摸对象，但他们无法感觉到它们。有大量的应用程序，其中它是有益的用户有他们的触摸增强与'感觉为基础的'触觉反馈。例如，医疗应用、虚拟训练和建模应用需要来自用户的精确控制，触觉反馈可以帮助用户有效地执行这些任务。这些应用证明了在交互式应用中用视觉反馈增强触觉反馈的益处。通常，视觉空间已经与力反馈断开连接，需要延长的训练期，使用户习惯于移动数字对象并在监视器上观看距离很小的交互。在这个建议中，我们将研究使用超声波换能器通过空气提供“可感觉的”反馈。人手上的皮肤可以感受到由一系列经过仔细校准的换能器产生的超声波压力波，其方式与立体声系统上响亮的低音炮明显相同。超声波在人类的听觉范围之外，因此提供无声的、通过空气的触觉反馈。我们将利用这项技术在多点触摸的水平表面上提供多点触觉反馈。该团队由来自计算机科学系的Sriram Subramanian博士、Mark马歇尔博士和Jason亚历山大博士以及来自布里斯托大学机械工程系的布鲁斯·德林克沃特教授和来自格拉斯哥大学计算机科学系的斯蒂芬·布鲁斯特教授组成。该团队因其在人机交互（HCI）、HCI硬件的新型集成和超声波传感器方面的研究而获得国际认可。微软研究院（剑桥）和XMOS将作为项目合作伙伴，为该项目提供宝贵的资源和支持。
