Subtle Interaction Techniques for Ubiquitous Displays

计算机正以嵌入式交互式显示器的形式遍布我们的生活环境，而全身追踪将成为一种主要的输入方式。这将彻底改变我们访问数字信息的方式、时间和地点。挑战在于，这种新的计算环境需要根本不同的方法来处理输入、交互和可视化等紧密相关的方面。对当前方法的两个主要担忧是，挥手示意输入很累人，而且会让人觉得在社交中很显眼，而寻求注意力的展示会增加认知需求，损害环境的视觉美学。然而，当互动变得微妙时（“在意义或意图上精细或微妙”），这些舒适和美学的组合问题就得到了最恰当的解决。这项工作发展并促进了“微妙交互”作为人机交互范式。利用我过去在与大型环境显示器交互方面的研究，拟议的研究最终以令人信服的应用程序在新颖的系统配置中实现，这些系统配置使用舒适，与建筑环境和谐。这些应用程序的构建将通过设计指南和评估模型的基本贡献来实现，这些模型和评估模型是从舒适性和美学的形成性工作中发展出来的，以及解决输入传感、可视化和交互设计等基础研究问题的创新技术。通过采用多阶段、多流程的方法，实现这些目标的过程也将为高素质人才提供多样化、协作性和激励性的培训机会。最终，这些工具和技术将使设计人员能够将微妙的交互应用到其他应用程序中，并领导研究人员在未来探索新系统配置和计算环境中的微妙交互问题。这一理论和实践将使嵌入式交互式显示器的全身交互发挥全部潜力，从而获得公众接受和商业可行性。

Computers are spreading throughout our environment as embedded interactive displays, and whole-body tracking is poised to become a primary method of input. This could radically change how, when, and where we access digital information. The challenge is that this new computing context requires fundamentally different approaches to the tightly linked aspects of input, interaction, and visualization. Two central concerns about current approaches are that waving your hands for input is tiring and feels socially conspicuous, and attention-seeking displays will add cognitive demands and compromise the visual aesthetics of the environment. However, when interaction is made subtle ("fine or delicate in meaning or intent"), these combined issues of comfort and aesthetics are addressed most appropriately. This work develops and promotes "subtle interaction" as a Human-Computer Interaction paradigm. Leveraging my past research in interaction with large ambient displays, the proposed research culminates with convincing applications realized in novel system configurations that are comfortable to use and harmonious with the architectural environment. The construction of these applications will be enabled by essential contributions of design guidelines and assessment models developed out of formative work in comfort and aesthetics, as well as innovative enabling techniques which address fundamental research problems in input sensing, visualization, and interaction design. By adopting a multi-phased, multi-streamed methodology, the process to reach these goals will also form a diverse, collaborative, and stimulating training opportunity for highly qualified personnel. Ultimately, these tools and techniques will equip designers to apply subtle interaction to other applications and lead researchers in future explorations of subtle interaction issues in new system configurations and computing contexts. This theoretical and practical will enable the full potential of whole-body interaction with embedded interactive displays, leading to public acceptance and commercial viability.
