EAGER: Interaction Can Hurt - Exploring a Gesture-Based Design Paradigm for Chronic Pain Sufferers

人类最常见的经历之一就是疼痛。 当事情不对劲时发出警告，当需要采取行动时发出警报，这是至关重要的。 但是，当疼痛持续超过3个月时，它被称为慢性疼痛，它可以剥夺那些遭受疼痛的人的生产力，精神健康，甚至可能是他们的生命。 随着一般人群的年龄增长，患有纤维肌痛和腕管综合征等慢性疼痛的人数将增加，这些患者需要计算机交互。 与此同时，由于新的商品技术（如Microsoft Kinect）的部署，各种主流应用程序越来越依赖于非接触式空中手势交互，作为非预期用户的鼠标/键盘范例的替代品。 随着这一趋势的加速并变得更加普遍，患有慢性疼痛相关疾病（CPD）的人将成为受影响最严重的人。 PI在这项探索性研究中的目标是通过为CPD用户开发手势交互的设计范例和最佳实践来缓解这一问题。项目成果不仅将深刻改变目标用户社区成员的日常生活，而是通过更广泛地推进手势的艺术水平，基于互动技术，他们也将减少其他用户发展未来的身体疾病的机会。为了这些目的，PI将建立在他的“个人空间”的手势互动方法，这允许用户限定交互区域以及在交互期间使他们的肘部休息。 他将分别考虑手势指向（使用用户的身体来控制交互位置和方向）和手势操作（用于在交互系统中保持，释放或选择项目的手势），寻找每个问题空间，以发现常见的非接触式手势交互的哪些改变对用户的疲劳，准确性和吞吐量有积极的影响。 使用自然和直观的手势，从文献中的操作，如抓取，捏和把握作为起点，实验将进行回答的问题，如什么是各种青睐的输入类型，以及哪些肌肉群在使用过程中最受影响。 其他输入选项，包括是否使用静态与动态手势，支持手部切换，以及基于语音的输入也将进行评估。 研究结果将被结合起来，以创建一个设计范例，以帮助塑造一个完整的基于手势的交互和最佳实践的用户与CPD。

One of the most common human experiences is pain. It is essential to warn when something is not right, and to alert when action needs to be taken. But when pain persists for longer than 3 months it is called chronic and it can rob those who suffer from it of their productivity, their mental well-being, and potentially even their lives. As the general population ages the number of people suffering from chronic pain induced by conditions such as Fibromyalgia and Carpal Tunnel Syndrome who require computer interaction will increase. Meanwhile, fueled by the deployment of new commodity technologies such as the Microsoft Kinect, there is a growing reliance in a variety of mainstream applications on touchless mid-air gesture-based interaction as an alternative to the mouse/keyboard paradigm for non-expect users. As this trend accelerates and becomes more widespread, people with chronic pain-related diseases (CPD) will be among those most negatively affected. The PI's goal in this exploratory research is to alleviate this problem by developing a design paradigm and best practices for gestural interaction for users with CPD. Not only will project outcomes profoundly change everyday life for members of the target user community, but by more generally advancing the state-of-the art in gesture-based interaction techniques they will also lessen the chance of other users developing future physical ailments.To these ends, the PI will build upon his "personal space" approach to gestural interaction, which allows the user to define the area of interaction as well as to rest their elbow during the interaction. He will consider separately gestural pointing (the use of a user's body to control interaction location and direction), and gestural manipulation (gestures used to hold, release, or select items within an interaction system), seeking for each problem space to discover which alterations to common touchless gesture interaction have a positive impact on users' fatigue, accuracy, and throughput. Using natural and intuitive gestures from the literature for operations such as grab, pinch and grasp as a starting point, experiments will be conducted to answer questions such as what are the various favored types of input, and which muscle groups are most affected during use. Other input options, including whether to use static vs. dynamic gestures, support for hand switching, and speech based input will also be evaluated. The findings will be combined to create a design paradigm to help shape a complete gesture-based interaction and best practices for users with CPD.
