Physical user interfaces communication of information and affect

触觉对于现实世界中的交流至关重要。相比之下，我们与日常现代技术的交流是非常贫乏的；我们被隔离到了某种程度，以至于身体已经变得不自然，产生了实际和美学上的后果。在一个相关的演变中，复杂而无处不在的人机系统扩展到汽车驾驶舱和手持设备等领域，使信息过载和持续中断成为一种生活方式。他们表示，使用基于心理物理的设计将触觉嵌入世界，既是恢复日常生活计算机化中丢失的东西的一条途径，也是一条旨在尊重和保护人类注意力这一日益宝贵的资源的新一代界面的途径。因此，我的研究项目的统一目标是在更广泛的交流环境中考虑触觉反馈，即人与机器或由机器中介的其他人之间的反馈。这项拟议的研究包括三个部分：(1)触觉图标感知设计的方法论。我的团队过去和正在进行的心理物理实验集中于揭示支持设计新的抽象触觉图像的基础。我们将利用这些数据开发一种新的程序性实验/分析技术，以有效地生成可区分和有意义的触觉图标集。2)系统共享控制的触觉指导。基于我们最近在类似驾驶环境中的触觉指导技术方面获得的知识，我们将继续开发和探索在基于乐器控制的新试验台环境中共享触觉中介、用户/系统控制的可能性和机制。(3)情感的双向触觉沟通。我们将使用最近完成的测试环境和初步结果来试验性地建立不同通信模式的基本属性。

Touch is crucial to communication in the real world. In contrast, our exchanges with everyday modern technology are haptically impoverished; we are insulated to an extent that physicality has come to feel unnatural, with practical and aesthetic consequences. In a related evolution, the spread of complex and pervasive human-machine systems into areas like automobile cockpits and handheld devices has made information overload and the constant interruptions a way of life.       Using psychophysically grounded design to embed haptics in the world is a path both to restoring what has been lost in the computerization of daily life, and to a new generation of interfaces designed with the goal of respecting and preserving that increasingly precious resource, human attention. The unifying goal of my research program is thus to consider haptic feedback in the broader context of communication, humans to machines or to other humans mediated by a machine. The proposed research has three parts:      1) Methodology for Perceptual Design of Haptic Icons.  My group's past and ongoing psychophysics experimentation has centered on revealing the foundation that will support the design of a new, abstract haptic iconography. We will use this data to develop a new procedural experimental/analytical technique to efficiently generate distinguishable and meaningful sets of haptic icons.      2) Haptic Guidance for Shared Control of Systems. Building on our recently gained knowledge in techniques for haptic guidance in driving-like contexts, we will continue to develop and explore possibilities and mechanisms for haptically-mediated, user/system control sharing in a new testbed environment based on musical instrument control.      3) Bidirectional Haptic Communication of Affect. We will use recently completed test environments and initial results to experimentally establish essential attributes of different communication modalities.
