Advances in haptic technologies can alter how real objects feel to our touch and create the experience of haptic augmented reality (AR). However, the definition, use cases, and value to end users of such haptic AR remain unclear. Existing work is concerned with technological implementation and lacks a user-centered perspective. To address these limitations, we analyze haptic AR systems in the literature to understand what constitutes haptic AR, why we would want to alter our sense of touch, and how haptic AR interactions take place. To demonstrate the value of studying haptic AR in the context of real-world tasks and user impressions of the concept itself, we also conducted a small exploratory study with five prototypical applications of different haptic AR systems. Our analysis highlights unexplored areas for haptics and HCI researchers and the need to conduct user evaluations of the overall concept rather than just point examples.

增强真实物体的感觉：触觉增强现实分析

触觉技术的进步可以改变我们触摸真实物体的感觉，并创造触觉增强现实 (AR) 的体验。然而，此类触觉 AR 的定义、用例和对最终用户的价值仍不清楚。现有的工作主要关注技术实现，缺乏以用户为中心的视角。为了解决这些局限性，我们分析了文献中的触觉 AR 系统，以了解触​​觉 AR 的构成、为什么我们想要改变触觉以及触觉 AR 交互是如何发生的。为了展示在现实世界任务和用户对概念本身的印象的背景下研究触觉 AR 的价值，我们还对不同触觉 AR 系统的五个原型应用进行了一项小型探索性研究。我们的分析强调了触觉和人机交互研究人员尚未探索的领域，以及对整体概念（而不仅仅是点示例）进行用户评估的必要性。
