项目摘要

Abstract IIS-9908675Hollerbach, JohnUniversity of Utah$75,000 - 12 mos.Motion Display in the Treadport Locomotion InterfaceLocomotion interfaces represent a new field, and at this early stagethere are many uncertainties about the best approaches. This exploratoryresearch is concerned with the mechanical display of slope,inertia, and turning on a treadmill-based locomotion interface, the Sarcos Treadport. The Sarcos Treadport comprises a linear tilting treadmill, an active mechanical tether, and a CAVE-like visual display. The active mechanical tether, which is the unique aspect of the Treadport,measures user position and applies axial forces to the user.Although the treadmill is a linear device, the research aims to show that thetether coupled to the visual display provides a reasonable basis forturning control. The force-producing capability of the active tetheroffers the unique ability to simulate inertial forces during running,which are otherwise absent because the user is stationary. Treadmilltilt mechanisms are typically too slow to display rapid slope changes.By pulling on the user to simulate uphill walking and pushing fordownhill walking, the active mechanical tether can simulate gravity.The PIs propose to conduct a series of biomechanical, modeling, andpsychophysical studies to demonstrate the proposed motion displays forturning, inertial force, and slope using an active mechanical tether.The objective is to show that adding a mechanical tether to linear treadmills is a useful and reasonable approach towards locomotion interfaces, and that the proposed locomotion display approaches have some scientific basis and are effective from a user standpoint.

摘要IIS -9908675 Hollerbach，犹他州的约翰尼大学$ 75,000-12 MOS.MOS.MOTION在Treadport运动中的动作互动Interfacelocomotion Interfaces代表了一个新领域，在这个早期的Stagethere上，许多对最佳方法的不确定性。这项探索性研究与斜率，惯性的机械显示有关，并打开了基于跑步机的机车界面Sarcos Treadport。 Sarcos踏板包括线性倾斜跑步机，一个主动的机械系绳和类似洞穴的视觉显示。主动机械系绳是踏板的独特方面，可以测量用户位置并将轴向力应用于用户。尽管跑步机是一种线性设备，但研究的目的是表明，与视觉显示相关的耦合提供了合理的基础。主动绳索的产生力的能力具有独特的能力，可以在运行过程中模拟惯性力，否则由于用户是静止的，因此缺失。跑步机的机制通常太慢，无法显示快速坡度的变化。通过吸引用户模拟上坡行走和推动行走的行走，主动的机械束缚可以模拟重力。PIS提议进行一系列生物力学，建模，心理物理学以证明该拟议的动作，并显示出稳固的动作，并展示了一个固定的动力，并构成稳固的力量。机械系绳至线性跑步机是一种有用的合理方法，用于运动接口，并且提出的运动显示方法具有一定的科学基础，并且从用户的角度有效。
