【摘要】 触觉作为人的一种独特的感官通道具有独特的优势,它不仅能最大限度的贴合人体的生理构造,传递硬度、大小、纹理、形状、温度等视听觉无法传递的信息,而且拥有快速准确的特性,触觉不仅可以实现全方位的感知,而且能够有效感知一些很难被视觉或听觉形式表达的更真实复杂的信息,和外界环境进行一系列的交互.振动触觉编码的设计是开发触觉的一个重要途径,也是未来人机交互的一种重要手段.本文从振动触觉感知机理入手,讨论了不同振动参数的振动触觉分辨率和振动信息编码理论,并按照方向导航和文字交互的应用对振动信息编码进行归纳总结,介绍了振动信息编码的实验手段和结论,最后展望了振动信息编码领域未来的发展前景.更多还原

【Abstract】 In recent years, with the progress and development of science and technology, the research on artificial intelligence and wearable devices continues to develop, and researchers increasingly find ways to provide a kind of more comfortable and comprehensive user experience. Auditory and visual technologies have been fully developed and utilized, while as an emerging field, tactile sense is a research direction with great potential. As a type of unique human sensory channel, tactile sense has unique advantages. It can convey information about maximum joints in physiological structure of human body, such as hardness, texture, shape, size, and temperature,which cannot be transmitted by visual and auditory senses. Additionally, the tactile sense is fast and accurate, thus, it performs well in some special situations, such as supergravity scenarios, high-speed rotating scenarios, or very noisy environments. The design of vibrational tactile coding is an important way to develop tactile devices and achieve a better human computer interaction. Haptic coding has several defects. It is used in narrow application scenes and conveys unclear meaning. Compared with the mature development of vision and hearing, it is necessary to further design the vibration haptic coding patterns to overcome these defects. Research on information transmission of tactile sense is very meaningful, for example, it offers convenience for special groups such as people with visual impairment or workers engaged in their education. It provides a navigation service for visually impaired people by changing the vibration frequency and vibration intensity of a blind vest. When hearing or vision is impaired, the tactile sense is a considerate way to provide timely and accurate information assistance to the special groups. Besides, tactile sense can help express the flight attitude information in virtue of combined vibration tactile coding. However, these studies aimed at providing a set of specific coding for a specific scenario in which relatively vague pieces of information were conveyed, such as emotion and direction Based on these studies, designing a set of universal coding patterns for most usage scenarios to deliver exact and accessible information is essential. This paperdiscussed the resolution of tactile vibration based on the mechanism of tactile vibration perception. According to the application of directional navigation and text interaction, the vibration information coding was summarized and the experimental methods and conclusions of vibration information coding were introduced. Moreover, the prospect of the vibration information coding field was proposed.更多还原
