近20年国际视力障碍领域定向行走研究的文献计量分析

International researches on orientation and mobility for visual impairments in the last two decades:a bibliometrics analysis

目的分析国际视力障碍领域定向行走研究的热点和发展趋势。方法检索2004年1月至2024年3月Web of Science核心合集数据库中关于视力障碍领域定向行走主题相关文献,采用CiteSpace 6.3 R1进行分析。结果共纳入197篇文献。国际视力障碍领域定向行走的文献数量呈增长趋势。Robert Wall Emerson、Kim Dae Shik、Nora Griffin-Shirley和Giulio E Lancioni的发文量位居前列。美国在视力障碍领域定向行走方面具有较高的研究产出和影响力。navigation(寻路)、assistive technology(辅助技术)、cognitive maps(认知地图)、older adults(老年人)、design(设计)、experience(经历)、children(儿童)、perception(感知)和acuity(敏锐度)是核心关键词。热点主题主要集中在低视力者的交通出行与康复、定向行走辅助技术发展、视力障碍多重残疾的定向行走研究、视力障碍者空间认知建构和基于多感官线索的寻路研究5个方面。学者从最初关注视力障碍人士基本生活需求和辅助技术的简单应用,到重视个人经历和实际需求,再到探索如何利用辅助技术提升生活质量和定向行走能力。结论定向行走的研究热度呈上升趋势,研究热点包括出行与康复、辅助技术、空间认知以及视力障碍多重残疾者等方面。未来应促进跨学科的研究和合作,并专注于定向行走辅助技术的开发和创新。

Objective To analyze the hotspots and development trends in orientation and mobility research within the international field of visual impairment.Methods Literature related to orientation and mobility in the field of visual impairment was retrieved from the Web of Science Core Collection database from January,2004 to March,2024,and was analyzed with CiteSpace 6.3 R1.Results A total of 197 literatures were included.The quantity of literature in the field of orientation and mobility for visual impairment showed a growth trend.The top scholars in this field by publication volume were Robert Wall Emerson,Kim Dae Shik,Nora Griffin-Shirley,and Giulio E Lancioni.The United States demonstrated high research output and influence in the study of orientation and mobility for individuals with visual impairments.Core keywords included navigation,assistive technology,cognitive maps,older adults,design,experience,children,perception and acuity.Hot topics primarily focused on five aspects:transportation and rehabilitation for low-vision individuals,development of orientation and mobility assistive technologies,orientation and mobility research for individuals with multiple disabilities due to visual impairment,construction of spatial cognition for visually impaired individuals,and navigation research based on multisensory cues.Scholars evolved their focus from the basic living needs and simple applications of assistive technologies for visually impaired individuals to an emphasis on personal experiences and actual needs,and finally to exploring how to utilize assistive technologies to enhance quality of life and orientation and mobility capabilities.Conclusion Researches in orientation and mobility are on the rise,with hot topics including transportation and rehabilitation,assistive technologies,spatial cognition,and individuals with multiple disabilities related to visual impairment.It is needed to promote interdisciplinary research and collaboration,while focus on the development and innovation of orientation and mobility assistive technologies.
