Abstract

This study aims to represent fine texture differences in pencil hardness using intensity segment modulation (ISM), a sensory equivalent conversion method of vibration from high to low frequencies. This method enables the presentation of delicate tactile sensations even with small transducers. We integrated this approach in the world's thinnest ultra-thin PZT-MEMS vibrator with a stylus-type device. The vibration waveforms of four types of pencil hardness were captured under the same conditions, and the differences in the frequency components were confirmed. We compared the fine texture feelings under raw signal, ISM, and ISM below 1 kHz conditions by conducting discrimination tests and subjective similarity evaluations. The results showed that ISM could reproduce similar feelings of the pencil hardness.

利用超薄 PZT-MEMS 振动器进行高频振动触觉等效转换，表现铅笔硬度的细微纹理。

这项研究旨在利用强度分段调制（ISM）来表现铅笔硬度的细微纹理差异，这是一种从高频到低频振动的感官等效转换方法。这种方法即使使用小型传感器也能呈现细腻的触感。我们将这种方法集成到了世界上最薄的超薄 PZT-MEMS 振动器中，该振动器带有一个触针型装置。我们在相同条件下捕捉了四种铅笔硬度的振动波形，并确认了频率成分的差异。我们通过进行辨别测试和主观相似性评价，比较了原始信号、ISM 和低于 1 kHz 的 ISM 条件下的精细纹理感觉。结果表明，ISM 可以再现类似的铅笔硬度感觉。

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.
