有形用户界面（TUIs）通过包括触觉、视觉和听觉在内的许多感官方式来表示数字信息。我们建议与有形界面的交互通常主要通过视觉线索来控制，尽管强调有形表现。我们不怀疑视觉反馈提供了丰富的交互指导，但认为强调触觉和听觉反馈可以在视觉分散或损伤的情况下支持或替代视觉。我们已经开发了一系列简单的ui，允许视觉隐藏纹理的触觉和听觉探索。我们的技术是将纹理的力反馈传递给用户，通过用户操纵的滚珠轴承对磁铁的吸引力。这允许纹理的细节呈现给用户，同时在视觉上呈现一个完全平坦的表面。不透明和透明材料的使用可以控制纹理的可见性，以进行比较。由此产生的可感觉用户界面（FUI），如图1所示，允许探索哪些纹理和结构对触觉指导有用。我们的触觉探索结果将提供关于触觉线索在与视觉上隐藏或在用户视觉外围的有形物体交互时的使用的基本理解。
Tangible User Interfaces (TUIs) represent digital information via a number of sensory modalities including the haptic, visual and auditory senses. We suggest that interaction with tangible interfaces is commonly governed primarily through visual cues, despite the emphasis on tangible representation. We do not doubt that visual feedback offers rich interaction guidance, but argue that emphasis on haptic and auditory feedback could support or substitute vision in situations of visual distraction or impairment. We have developed a series of simple TUIs that allows for the haptic and auditory exploration of visually hidden textures. Our technique is to transmit the force feedback of the texture to the user via the attraction of a ball bearing to a magnet that the user manipulates. This allows the detail of the texture to be presented to the user while visually presenting an entirely flat surface. The use of both opaque and transparent materials allows for controlling the texture visibility for comparative purposes. The resulting Feelable User Interface (FUI), shown in Fig. 1, allows for the exploration of which textures and structures are useful for haptic guidance. The findings of our haptic exploration shall provide basic understanding about the usage of haptic cues for interacting with tangible objects that are visually hidden or are in the user's visual periphery.
