项目摘要
Lack of physical activity is a serious health concern for individuals with visual impairments. In particular, children with visual impairments have limited access to physical education, recreation, and athletic programs for a variety of reasons including fear of injury, safety concerns of parents and teachers, and lack of sighted guides with whom to exercise. The PI's hypothesis is that video games, which have been identified as a contributing factor to the increasingly sedentary behavior of children in general and associated higher levels of obesity, may provide a solution. A new genre of "exergames" use upper and/or lower-body gestures (such as steps, punches, and kicks directed at virtual targets), to provide players with an immersive experience that engages them in moderate-to-vigorous physical activity that is high enough to yield health benefits. The PI's goal in this project is to investigate how proprioceptive displays can be designed and built to facilitate exercise games for blind adolescents. Proprioception, the ability to sense the position and orientation of one's body and its parts, is an interoceptive sensory modality distinct from exteroceptive sensory modalities such as sight, touch, and hearing, and has remained largely unexplored as a modality of feedback. In performing a gesture we generally combine visual and proprioceptive information, but once the location of a target has been memorized proprioceptive feedback alone is sufficient for relating the position of the user's limb to the target. Since the location of a target primarily is acquired visually, gestures are difficult to perform for users with visual impairments. This project will test the hypothesis that whole body gestures can be performed by blind users in exergames when target direction is acquired using a proprioceptive display.In prior work, the PI has explored single proprioceptive displays for acquiring the direction to a target in a horizontal plane by having users scan a horizontal line with a hand-held orientation aware device; a vibrotactile cue was used to indicate when the device was pointed at the target, with target direction conveyed to the user using proprioception. Preliminary results have demonstrated that blind users can perform an upper body gesture aimed at a target in a plane where direction to the target is acquired using a proprioceptive display. This project will significantly advance our understanding of proprioceptive displays by: (1) quantifying spatial and temporal resolutions of discrete proprioceptive displays; (2) developing efficient scanning strategies for conveying points in a plane (directions to points in a space) using an analog proprioceptive display and determining the effectiveness of using multiple proprioceptive displays; (3) investigating the efficacy with which whole-body directed gestures can be performed using proprioceptive displays; and (4) establishing whether rhythmic sequences of whole-body directed gestures performed using a proprioceptive display can be memorized using audio cues. Through generation of empirical data with exergames that involve whole-body gestures, this project will develop a fundamental and transformative understanding of proprioceptive displays in order to articulate a set of principles for their design. Broader Impacts: Children with visual impairments have significantly higher levels of obesity and often exhibit delays in motor development caused by a general lack of opportunities to be physically active. Through development of open-source exergames that can be played using commercial off-the-shelf controller technology without the aid of a sighted guide and with minimal risk of injury, this project will increase existing exercise and socialization opportunities for members of this vulnerable population. More generally, because proprioceptive displays can be implemented using low cost technology that is often already present in mobile devices, these displays may ultimately facilitate the development of robust ear- and eye-free forms of interaction for everyone (e.g., for motor rehabilitation or sports training). This research will directly involve both graduate and undergraduate students, and the PI will use this work as the basis for compelling design projects in his courses. The PI will also develop outreach efforts such as summer camps for K-12 students with visual impairments (and other minorities) in order to attract them to computer science and STEM.
缺乏体力活动是视力障碍患者的一个严重的健康问题。特别是,由于害怕受伤、父母和教师的安全担忧以及缺乏与之一起锻炼的视力导游等各种原因,视力障碍儿童获得体育课、娱乐和体育计划的机会有限。PI的假设是,电子游戏可能提供了一种解决方案。电子游戏被认为是导致儿童日益久坐的行为和相关的更高水平肥胖症的一个因素。一种新的“锻炼游戏”使用上半身和/或下半身的手势(如针对虚拟目标的步伐、拳头和踢腿),为玩家提供身临其境的体验,让他们参与到足以产生健康益处的中等到剧烈的身体活动中。PI在这个项目中的目标是调查如何设计和建造本体感知显示器来促进盲人青少年的锻炼游戏。本体感觉是一种感觉身体及其部分的位置和方向的能力,是一种不同于视觉、触觉和听觉等外部感觉形式的内部感觉形式,作为一种反馈形式在很大程度上仍未被探索。在进行手势时,我们通常将视觉和本体感觉信息结合在一起,但一旦记住了目标的位置,仅本体感觉反馈就足以将用户肢体的位置与目标联系起来。由于目标的位置主要是通过视觉获得的,因此对于有视觉障碍的用户来说,很难执行手势。这个项目将测试这样一个假设,即当使用本体感知显示器获取目标方向时,盲人用户可以在游戏中执行全身手势。在之前的工作中,PI已经探索了单一本体感知显示器,通过让用户使用手持方向感知设备扫描水平线来获取指向水平平面上的目标的方向;使用振动触觉提示来指示设备何时指向目标,目标方向使用本体感知传达给用户。初步结果表明,盲人用户可以在使用本体感知显示器获取目标方向的平面上对着目标执行上半身手势。这个项目将极大地促进我们对本体感知显示器的理解:(1)量化离散本体感知显示器的空间和时间分辨率;(2)开发高效的扫描策略,使用模拟本体感知显示器在平面上传递点(指向空间中的点的方向),并确定使用多个本体感知显示器的有效性;(3)研究使用本体感知显示器执行全身定向手势的有效性;以及(4)建立使用本体感知显示器执行的全身定向手势的节奏序列是否可以使用音频提示记忆。通过使用涉及全身手势的运动游戏生成经验数据,该项目将发展对本体感知显示器的基本和变革性的理解,以便阐明其设计的一套原则。更广泛的影响:视力障碍儿童的肥胖率明显更高,而且通常由于缺乏运动机会而导致运动发育迟缓。通过开发开放源码的运动游戏,该项目将增加这一弱势群体成员现有的运动和社交机会,这些游戏可以在没有视力指导的情况下使用商业现成的控制器技术进行游戏,并将受伤风险降至最低。更广泛地说,因为本体感知显示器可以使用通常已经存在于移动设备中的低成本技术来实现,所以这些显示器可能最终促进每个人(例如,用于运动康复或运动训练)的健壮的无耳和无眼交互形式的发展。这项研究将直接涉及研究生和本科生,PI将把这项工作作为他课程中引人注目的设计项目的基础。国际学生联合会还将开展外联工作,如为视力有障碍的K-12学生(和其他少数群体)举办夏令营,以吸引他们学习计算机科学和STEM。
