Augmented reality (AR) applications have gained much research and industry attention. Moreover, the mobile counterpart—mobile augmented reality (MAR) is one of the most explosive growth areas for AR applications in the mobile environment (e.g., smartphones). The technical improvements in the hardware of smartphones, tablets, and smart-glasses provide an advantage for the wide use of mobile AR in the real world and experience these AR applications anywhere. However, the mobile nature of MAR applications can limit users’ interaction capabilities, such as input and haptic feedback. In this survey, we analyze current research issues in the area of human-computer interaction for haptic technologies in MAR scenarios. The survey first presents human sensing capabilities and their applicability in AR applications. We classify haptic devices into two groups according to the triggered sense: cutaneous/tactile : touch, active surfaces, and mid-air; kinesthetic : manipulandum, grasp, and exoskeleton. Due to MAR applications’ mobile capabilities, we mainly focus our study on wearable haptic devices for each category and their AR possibilities. To conclude, we discuss the future paths that haptic feedback should follow for MAR applications and their challenges.

移动增强现实触觉技术调查

增强现实 (AR) 应用已获得大量研究和行业关注。此外，移动对应物——移动增强现实（MAR）是移动环境（例如智能手机）中 AR 应用最具爆炸性增长的领域之一。智能手机、平板电脑和智能眼镜硬件的技术改进为移动 AR 在现实世界中的广泛使用提供了优势，并在任何地方体验这些 AR 应用。然而，MAR 应用程序的移动特性会限制用户的交互能力，例如输入和触觉反馈。在本次调查中，我们分析了 MAR 场景中触觉技术的人机交互领域的当前研究问题。该调查首先介绍了人类感知能力及其在 AR 应用中的适用性。皮肤/触觉：触摸、活动表面和半空中；动觉：manipulandum、抓握和外骨骼。由于 MAR 应用程序的移动功能，我们主要研究每个类别的可穿戴触觉设备及其 AR 可能性。最后，我们讨论了触觉反馈在 MAR 应用程序中应该遵循的未来路径及其挑战。
