Abstract

This article introduces a novel system designed to convey the three-dimensional positions surrounding the user. The system incorporates circumferential vibrotactile arrays strategically positioned on both the user's head and waist. Through the synergy of this two-dimensional arrangement and modulations in vibration amplitude, the system adeptly presents comprehensive three-dimensional positional information. Two prototypes, namely a spherical model and a cylindrical model, were employed as mappings between three-dimensional positions and vibration amplitudes. In Experiment 1, we evaluated the system's performance in indicating positions in depth, orientation, and height. Notably, discrimination rates for depth (Task 1) and orientation (Task 2) were 60% and 54%, respectively. Regarding height discrimination in the head-to-waist condition (Tasks 3 and 4), the cylindrical model outperformed the spherical model (54% and 52% vs. 32% and 36%). Conversely, in the head-above and waist-below condition (Task 5), the cylindrical model achieved a discrimination rate of 45%, while the spherical model did not. In Experiment 2, we explored the use of the cylindrical model to convey a moving three-dimensional position. The results showed an impressive 81% correct response rate, affirming the system's effectiveness in presenting three-dimensional motion stimuli.

通过头部和腰部可控振动阵列的三维位置演示。

本文介绍了一种新颖的系统，旨在传达用户周围的三维位置。该系统结合了周向振动触觉阵列，该阵列战略性地定位在用户的头部和腰部。通过这种二维排列和振幅调制的协同作用，该系统熟练地呈现了全面的三维位置信息。两个原型，即球形模型和圆柱形模型，被用作三维位置和振幅之间的映射。在实验1中，我们评估了该系统在指示深度、方向和高度位置方面的性能。值得注意的是，深度（任务1）和定向（任务2）的辨别率分别为60%和54%。关于头到腰条件下的身高辨别（任务3和4），圆柱形模型的表现优于球形模型（54%和52%对32%和36%）。相反，在头部以上和腰部以下的情况下（任务5），圆柱形模型的识别率为45%，而球形模型则没有。在实验2中，我们探索了使用圆柱形模型来传递移动的三维位置。结果显示，81%的正确反应率令人印象深刻，肯定了该系统在呈现三维运动刺激方面的有效性。

期刊介绍： IEEE Transactions on Haptics (ToH) is a scholarly archival journal that addresses the science, technology, and applications associated with information acquisition and object manipulation through touch. Haptic interactions relevant to this journal include all aspects of manual exploration and manipulation of objects by humans, machines and interactions between the two, performed in real, virtual, teleoperated or networked environments. Research areas of relevance to this publication include, but are not limited to, the following topics: Human haptic and multi-sensory perception and action, Aspects of motor control that explicitly pertain to human haptics, Haptic interactions via passive or active tools and machines, Devices that sense, enable, or create haptic interactions locally or at a distance, Haptic rendering and its association with graphic and auditory rendering in virtual reality, Algorithms, controls, and dynamics of haptic devices, users, and interactions between the two, Human-machine performance and safety with haptic feedback, Haptics in the context of human-computer interactions, Systems and networks using haptic devices and interactions, including multi-modal feedback, Application of the above, for example in areas such as education, rehabilitation, medicine, computer-aided design, skills training, computer games, driver controls, simulation, and visualization.
