SGER: A Physically Animated Desktop Computer for Healthful Movement

其他人先前的工作已经建立了静态坐姿和背部不适之间的相关性，因此随着久坐工作在工作场所变得越来越普遍（例如，随着长时间使用电脑），肌肉骨骼问题，特别是下背痛的发病率也在上升。身体运动已被证明是预防背痛的关键措施;当人们可以在一天中改变姿势时，他们能够更好地长时间坐着。 将健康运动引入日常计算机使用的潜在好处导致PI从根本上重新思考当前的台式计算机设计，目标是将其静态性质转变为移动和邀请运动。 在这个项目中，PI将探索如何在人机交互中实现与运动相关的好处，通过设计和制造一个原型物理动画计算机，其中桌面显示器具有以微妙的表达方式响应用户的移动能力。 通过一项旨在研究移动屏幕的人体工程学的人类受试者研究，PI将评估用户坐在电脑前时是否可以增加移动量，而不会对任务性能或体验质量产生负面影响。 人和计算机的相互运动是否可以被设计成促进背部健康，而不会分散用户的注意力或使用户感到厌烦？ 这样的运动，以及它与情感和认知的相互作用，是否可以被设计成提高计算机使用的效率？ PI相信这是可能的，因为文献中的新理论将身体姿势及其对认知和情感的影响联系起来。 这项工作的成果将是一套如何将健康的运动引入有效的台式电脑使用的设计原则，以及人机交互中人体工程学运动的初步理论。更广泛的影响：这项工作将为一项新技术建立概念验证，并将为人机交互的新研究方向奠定最初的重要理论基础，探索将人机工程学纳入人机交互的有趣可能性。人机互动的运动既有利于健康，也是促进业绩和学习成果的潜在手段。

Prior work by others has established a correlation between static seated postures and back discomfort, so that as sedentary jobs become more prevalent in the workplaces (e.g., with prolonged sessions of computer use), the incidence of musculo-skeletal problems, in particular lower back pain, is also on the rise. Physical movement has been shown to be a key preventative measure for back pain; individuals are better able to sit for prolonged periods when they can change their posture throughout the day. The potential benefit of introducing healthy movement into daily computer use has led the PIs to fundamentally rethink current desktop computer design, with the goal of transforming its static nature to one that moves and invites movement. In this project, the PIs will explore how movement-related benefits can be achieved in human-computer interaction, by designing and fabricating a prototype physically animated computer wherein the desktop monitor possesses the ability to move in subtly expressive ways that respond to its user. Through a human subject study designed to investigate the ergonomics of a moving screen, the PIs will evaluate whether the user's movement can be increased while sitting at a computer without negatively impacting task performance or quality of experience. Can the reciprocal movement of human and computer be designed to promote back health, without being distracting or annoying to the user? Can such movement, and its interaction with affect and cognition, be designed to improve the efficacy of computer use? The PIs believe this is possible in light of new theories in the literature that link physical posture and its influence on cognition and affect. The outcome of this work will be a set of design principles for how to introduce healthy movement into effective desktop computer usage, as well as an initial theory for ergonomic movement in human-computer interaction.Broader Impacts: This work will establish a proof of concept for a novel technology, and will lay an initial and important theoretical foundation for new lines of research in HCI that explore the intriguing possibilities of incorporating ergonomic movement in human-computer interaction both for health benefits and also as a potential means to foster performance and learning gains.
