Mobile users lose a lot of time on their smartphones. They interact even with busy hands (hands-free interactions), distracted eyes (eyes-free interactions) and in different life situations (while walking, eating, working, etc.). The Time Well Spent (TWS) is a movement that aims to design applications which respect the users choices and availability. In this paper, we discuss how the multimodal mobile interactions and the TWS movement can support each other to protect the users time. We start by giving an overview of mobile multimodal interaction and highlighting the TWS concept. Then, we present our vision about applying mobile multimodality as a means to protect the users time. We show that multimodality can support the TWS by encouraging self-restraint, while the TWS supports multimodality by making the interaction modalities meaningful. Finally, we discuss our future works in this context.

多模式移动互动花费的时间

移动用户在智能手机上浪费大量时间。他们甚至可以用忙碌的手（免手互动），分散注意力的眼睛（无眼互动）以及在不同的生活状况（在散步，吃饭，工作等时）进行互动。花费的时间（TWS）是一项旨在设计尊重用户选择和可用性的应用程序的运动。在本文中，我们讨论了多模式移动交互和TWS运动如何相互支持以保护用户时间。我们首先概述了移动多模式交互，并着重强调了TWS概念。然后，我们提出了关于应用移动多模式作为保护用户时间的一种构想。我们表明多模式可以通过鼓励自我约束来支持TWS，而TWS通过使交互模式有意义而支持多模式。最后，我们在此背景下讨论我们的未来工作。
