在为移动的设备设计界面时，考虑到使用环境的多样性是很重要的。我们提出了一项研究，探讨如何改变环境中的噪音和干扰影响用户的表现，在触摸屏打字任务的界面，通过视觉，视觉和触觉，或视觉和听觉反馈。这项研究的目的是显示在什么确切的环境水平的音频或触觉反馈变得无效。结果表明，在94 dB及以上的水平下，音频反馈的性能显著下降，而在9.18g/s的振动水平下，触觉反馈的性能也显著下降。这些结果表明，在这些层面上，反馈应提出不同的方式。这些发现将允许设计者利用传感器使能的移动的设备，以适应用户的当前上下文提供的反馈。
When designing interfaces for mobile devices it is import-ant to take into account the variety of contexts of use. We present a study that examines how changing noise and dis-turbance in the environment affects user performance in a touchscreen typing task with the interface being presented through visual only, visual and tactile, or visual and audio feedback. The aim of the study is to show at what exact environmental levels audio or tactile feedback become inef-fective. The results show significant decreases in perform-ance for audio feedback at levels of 94dB and above as well as decreases in performance for tactile feedback at vibration levels of 9.18g/s. These results suggest that at these levels, feedback should be presented by a different modality. These findings will allow designers to take advantage of sensor enabled mobile devices to adapt the provided feed-back to the user's current context.
