Abstract

Virtual tactile bumps and dents are presented by controlling frictional forces on a surface tactile display, a flat touch screen with tactile feedback functions. This technology enables users to touch and feel three-dimensional objects. The resistive force against a sliding finger is increased and then decreased compared to a base level to present a bump. The order of increase and decrease is inverted for a dent. Thus, the difference between bump and dent presentations lies in the change order of the resistive force. However, bumps and dents are not simply opposite when investigating psychophysical functions with only lateral force cues available, without height and depth information. The results demonstrate that bumps are more easily detected with high surface gradients or resultant force changes and small widths. In contrast, these parameters do not influence the detection of dents among different participants. These findings contribute to a deeper understanding of tactile perception of surface shapes.

在使用侧向力线索进行探索时，凹凸并不是对立的。

通过控制表面触觉显示器（具有触觉反馈功能的平面触摸屏）上的摩擦力，可以呈现虚拟的凹凸触觉。这项技术能让用户触摸和感受三维物体。与基本水平相比，手指滑动时所受到的阻力会增大，然后减小，从而产生凹凸感。凹痕的增大和减小顺序相反。因此，凹凸的区别在于阻力的变化顺序。然而，在只有侧向力线索而没有高度和深度信息的情况下研究心理物理功能时，凹凸并不简单地相反。研究结果表明，表面梯度大或产生的力变化大、宽度小的地方更容易检测到凹凸。相反，这些参数并不影响不同参与者对凹痕的检测。这些发现有助于加深对表面形状触觉感知的理解。

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.
