无障碍设计研究:面向听障人群的振动触觉音乐体验

Accessibility design research:Vibrotactile music experience for hearing impaired people

虽然听觉通道受损,聋人群体也有欣赏音乐的需求、能力和权利。当前,现代化听觉辅助技术仍然无法很好地满足听障人群对于听觉艺术的感知和欣赏需求,不利于这一群体的社会交往和自我发展。聚焦听障人群的音乐活动需求和偏好,提出通过触觉来感受声波的振动是聋人参与音乐活动的常见形式。综述了触觉刺激对听觉信息的表征优势,振动触觉的音乐表达能力、局限性和设计方法,并梳理了可穿戴和静态振动触觉音乐设备的研究发展。触觉具备认知负担小、时序性强、自然感强、沉浸感强等优势,通过感官代偿设计,在补偿听觉损失、增益听觉感知的同时,还可以承载一定的情感传达作用。然而,振动触觉也具有分辨率较低、难以感知高频段信息等局限性。展望了未来的体验设计研发的方向和趋势。

Hearing impaired people have the need,ability and right to enjoy music,however modern hearing aid technologies still unable to meet their needs for music perception and appreciation,which is not conducive to their social interaction and selfdevelopment.This paper firstly focuses on the needs and preferences of hearing impaired people in music activities,and emphasizes that the common way for deaf people to participate in music activities is to feel the vibration of sound waves through tactile channel.Secondly,it summarizes the advantages of tactile stimulation in representing auditory information,as well as the expressiveness competence,limitations and design methods of vibrotactile music,and reviews related works of wearable and static vibrotactile music devices.Tactile channel has advantages in several aspects such as cognitive load,temporal sequence,naturalness and immersiveness etc,not only it can compensate for hearing loss and enhance hearing perception,but also carry emotional communication.It also has limitations such as low resolution and difficulty in conveying high-frequency information.Finally,this paper proposes several research directions of UX design in the future,to provide reference for researchers in related fields.
