Subtle Interaction Techniques for Ubiquitous Displays

计算机作为嵌入式交互显示器正在我们的环境中传播，全身跟踪有望成为主要的输入方法。这可能会从根本上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从根本上不同的方法来处理输入、交互和可视化的紧密联系。目前的方法有两个核心问题，一是挥手输入很累，感觉很显眼，二是寻求注意力的显示会增加认知需求，损害环境的视觉美感。然而，当交互变得微妙时（“意义或意图上的精细或微妙”），这些舒适和美学的综合问题得到了最恰当的解决。这项工作的发展和促进“微妙的互动”作为人机交互的范例。利用我过去在与大型环境显示器交互方面的研究，所提出的研究最终以令人信服的应用程序实现，这些应用程序采用新颖的系统配置，使用舒适，与建筑环境和谐。这些应用程序的建设将使基本贡献的设计准则和评估模型的形成工作的舒适性和美学，以及创新的使能技术，解决基本的研究问题，在输入传感，可视化和交互设计。通过采用多阶段、多流程的方法，实现这些目标的过程还将为高素质人员提供多样化、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师能够将微妙的交互应用于其他应用程序，并引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全身互动与嵌入式互动显示的全部潜力，导致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.
