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。

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.
