项目摘要

Prop ID: 0413204 P I: Colgate, J. Edward Organization: Northwestern University Title: Variable Compliance Haptic Field Displays AbstractThis research will address a novel class of haptic devices: "Haptic Field Displays" (HFDs). HFDs are large scale arrays of moveable pins or "tactels" covered by a flexible graphical display. HFD pin arrays will be much like the "tactile arrays" that have been developed for displaying Braille or virtual environments, but with some key differences. For instance, HFDs will be full-screen enabling scanning with the fingertip or using multiple fingers. They will operate not by actively controlling the displacement or force of each tactel, but by controlling compliance. The intellectual merit of this research stems from two sets of studies. The first is a set of psychophysical studies that will provide quantitative specifications for HFDs including the necessary dynamic range of tactel compliance and the resolution (or just noticeable difference) of compliance. These studies will also lead to an initial set of HFD primitives that naturally encode affordances (such as pushing, sliding or rotating). Finally, these experiments will assess human operator performance in using HFDs, especially in spatial localization and analog level-setting tasks. The second set of studies will address the design and integration of electronically programmable HFD tactels, each a meso-scale mechatronic system including a variable compliance mechanism, actuation and sensing. These studies will focus on the meso-scale realization of two low power "semi-active" approaches: variable damping achieved by controlling an orifice, and variable compliance achieved by placing a continuously variable transmission (CVT) between the fingertip and compliant element. Broader impacts of this research include the potential to improve the usability of graphical interfaces for normally-abled populations, as well as increase the accessibility of interfaces for differently-abled populations such as the elderly, those with low vision, and those who are blind. In addition, it has the potential to increase safety and utility in situations where high demands are placed on vision. For instance, HFDs would allow automobile drivers to focus visual attention on the road while simultaneously taking advantage of the growing assortment of electronic devices that may be found in a vehicle. This research will also impact undergraduate and graduate education at Northwestern more generally: tactel design and control will be integrated into at least two project-based courses taught by the P.I.s.
产品编号:0413204 PI:高露洁,J.爱德华 组织:西北大学 标题:可变顺应性触觉场显示器 摘要本研究将解决一类新的触觉设备:“触觉场显示器”(HFD)。 HFD是由柔性图形显示器覆盖的可移动引脚或“tactel”的大规模阵列。 HFD引脚阵列将非常类似于为显示盲文或虚拟环境而开发的“触觉阵列”,但有一些关键的区别。 例如,HFD将是全屏的,可以用指尖或多个手指进行扫描。 它们不是通过主动控制每个战术单位的位移或力量来运作的,而是通过控制服从来运作的。 这项研究的学术价值来自两组研究。 第一个是一组心理物理学研究,将提供定量规格的HFD,包括必要的动态范围的战术遵守和决议(或只是明显的差异)的遵守。 这些研究还将产生一组初始的HFD基元,这些基元自然地编码示能表示(例如推动、滑动或旋转)。 最后,这些实验将评估人类操作员使用HFD的性能,特别是在空间定位和模拟电平设置任务中。 第二组研究将解决电子可编程HFD tactels的设计和集成,每个中尺度机电系统,包括一个可变的顺应性机制,致动和传感。 这些研究将集中在中尺度实现两个低功率的“半主动”的方法:可变阻尼通过控制一个孔,和可变的顺应性通过放置一个无级变速器(CVT)之间的指尖和顺应性元件实现。 这项研究的更广泛的影响包括提高正常人群图形界面可用性的潜力,以及增加不同能力人群(如老年人,视力低下者和盲人)界面的可访问性。 此外,在对视力有高要求的情况下,它有可能提高安全性和实用性。 例如,HFD将允许汽车驾驶员将视觉注意力集中在道路上,同时利用可能在车辆中发现的越来越多的电子设备。 这项研究也将影响本科和研究生教育在西北更普遍:战术设计和控制将被整合到至少两个基于项目的课程由PI教授。
