This chapter explores the design of tactile user interfaces (TUIs) for pin-array displays, focusing on integrating Braille text and tactile graphics to support visually impaired users beyond single-line Braille displays. It details the haptic modalities enabled by pin-arrays, including static/dynamic pin patterns, symbols, textures, and animations, and how users perceive these tactile objects. The core challenge lies in designing effective interaction methods, particularly gestural input (taps, strokes, circles) detected via touch-sensitive surfaces, to overcome limitations like the “Midas touch” problem where exploration and selection must be disambiguated. The chapter examines specific TUI components and techniques: selection methods (e.g., cursor routing, two-step tap/double-tap), navigation aids (tactile scrollbars, overviews), spatial manipulation (zooming, panning, multi-view strategies like tiling windows), and multimodal integration with audio (speech output/sonification, voice input) to compensate for the displays’ low resolution. While TUIs for multi-line text are straightforward, presenting and interacting with complex tactile graphics demands specialized approaches for visualization, orientation, and widget design to ensure usability and task efficiency. Key considerations include maintaining context during navigation, designing recognizable low-resolution symbols, and balancing multimodal feedback to avoid cognitive overload.
