触觉阵列使用单个可控元素的矩阵来呈现皮肤信息的空间和时间模式。这种类型的早期设备是在感官替代领域，用于代替有感官障碍的用户的视觉或听觉。由于将触觉显示器用于远程机器人和虚拟现实，以表示与远程或模拟环境的物理接触，因此取得了许多进展。然而，其中许多都局限于工程原型。最近可负担得起的便携式触觉引脚阵列的商业可用性为将该技术应用于感官替代应用提供了新的动力。无法获得数字化存储的数据可能是盲人在数学领域寻求职业的一个重大障碍。触觉显示器可能以一种直观的非视觉方式提供一种离散和便携的方式来访问图形信息。本文介绍了用市售触觉阵列设备进行的与理解图形和简单可视化相关的触觉感知实验的结果。结果发现，受试者对正负线梯度的辨别能力在水平±4.7°范围内，而使用力反馈鼠标的结果为±3.25°，使用抬高纸表示的结果为±2.42°。
Tactile arrays use a matrix of individually controllable elements to present spatial and temporal patterns of cutaneous information. Early devices of this type were in the field of sensory substitution to replace vision or hearing for users with a sensory impairment. Many advances have been made due to the appropriation of tactile displays for telerobotics and virtual reality, to represent physical contact with a remote or simulated environment. However, many of these have been limited to engineering prototypes. The recent commercial availability of affordable, portable tactile pin arrays has provided renewed impetus to apply the technology to sensory substitution applications. Lack of access to digitally stored data can prove a significant barrier to blind people seeking careers in numerate disciplines. Tactile displays could potentially provide a discrete and portable means of accessing graphical information in an intuitive non-visual manner. Results are presented from experiments on tactual perception related to understanding graphs and simple visualisations with a commercially available tactile array device. It was found that subjects could discriminate positive or negative line gradient to within ±4.7° of the horizontal, compared to ±3.25° for results with a force feedback mouse and ±2.42° with a raised paper representation.
