Abstract

Physically accurate (authentic) reproduction of affective touch patterns on the forearm is limited by actuator technology. However, in most VR applications a direct comparison with actual touch is not possible. Here, the plausibility is only compared to the user's expectation. Focusing on the approach of plausible instead of authentic touch reproduction enables new rendering techniques, like the utilization of the phantom illusion to create the sensation of moving vibrations. Following this idea, a haptic armband array (4x2 vibrational actuators) was built to investigate the possibilities of recreating plausible affective touch patterns with vibration. The novel aspect of this work is the approach of touch reproduction with a parameterized rendering strategy, enabling the integration in VR. A first user study evaluates suitable parameter ranges for vibrational touch rendering. Duration of vibration and signal shape influence plausibility the most. A second user study found high plausibility ratings in a multimodal scenario and confirmed the expressiveness of the system. Rendering device and strategy are suitable for a various stroking patterns and applicable for emerging research on social affective touch reproduction.

基于幻影的振动触觉渲染情感触摸模式

前臂上情感触摸模式的物理精确（真实）再现受到执行器技术的限制。然而，在大多数 VR 应用中，与实际触摸进行直接比较是不可能的。在这里，可信度只与用户的期望值进行比较。将重点放在似真似幻而不是真实触感的再现上，可以实现新的渲染技术，比如利用幻影错觉来创造移动振动的感觉。根据这一想法，我们制作了一个触觉臂带阵列（4x2 个振动致动器），以研究用振动再现似是而非的情感触摸模式的可能性。这项工作的新颖之处在于采用参数化渲染策略进行触感再现，从而实现了与 VR 的整合。第一项用户研究评估了振动触感渲染的合适参数范围。振动持续时间和信号形状对可信度的影响最大。第二项用户研究发现，多模态场景中的可信度很高，并确认了系统的表现力。渲染设备和策略适用于各种抚摸模式，适用于社会情感触觉再现的新兴研究。

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.
