虚拟环境(VE)已被证明对身体康复有益，增加了动力和可以安全进行的运动范围。然而，关于残疾如何影响用户对VE的反应，这可能会影响康复动机，人们知之甚少。因此，这项研究的主要目标是了解VE如何影响移动障碍(MI)用户。具体地说，我们调查了拥有拐杖的全身化身的影响。为了开始研究这一点，我们设计了一种VE，其中包括一系列多通道反馈来诱导强烈的临场感，并且对参与者来说是新颖的。使用这种VE，我们对两个不同的人群进行了一项研究：8名MI患者和8名健康人作为对照。健康参与者的人口统计数据(例如，年龄、体重、身高和既往的VE经历)与使用拐杖走路的MI参与者相似(即，基于严格的选择标准以保持同质性)。这是第一个研究VE如何通过MI、生理反应、存在、行为和化身的影响来影响用户步态的研究之一。研究结果为心肌梗塞患者的VES设计提供了一般性的指导方针。版权所有©2014 John Wiley&Sons，Ltd.
Virtual environments (VEs) have been shown to be beneficial in physical rehabilitation, increasing motivation and the range of exercises that can be safely performed. However, little is known about how disabilities may impact a user's responses to a VE, which could affect rehabilitation motivation. Thus, the primary objective of this research is to understand how VEs affect users with mobility impairments (MI). Specifically, we investigate the influence of full body avatars that have canes. To begin investigating this, we designed a VE that included a range of multimodal feedback to induce a strong sense of presence and was novel to the participants. Using this VE, we conducted a study with two different populations: eight persons with MI and eight healthy persons as a control. The healthy participants were of similar demographics (e.g., age, weight, height, and previous VE experience) to the participants with MI who walked with a cane (i.e., on the basis of strict selection criteria to maintain homogeneity). This is one of the first studies to investigate how a VE can affect the gait of the users with MI, physiological response, presence, behavior, and the influence of avatars. Results of the study suggest generalizable guidelines for the design of VEs for users with MI. Copyright © 2014 John Wiley & Sons, Ltd.
