出行和移动是人类生活中必不可少的一项活动，从表面上看出行似乎是一个简单的位置移动的过程，但在实际中的复杂程度远超想象，整个出行活动中不仅存在大量的影响要素，还涉及到最为重要的信息捕捉和处理环节，这些都需要视觉器官的辅助，对于视觉障碍者来说出行成为了极大的挑战。本论文正是在此背景下展开的研究，通过文献计量研究和历史研究对视觉障碍者的出行方式、技术、辅具发展以及视觉障碍者出行领域的文献热点进行了计量和分析，发现了该领域的研究空缺，即视觉障碍者真实使用的辅具与当下视障电子出行辅具开发的脱节，同时提出研究问题，即设计师如何介入视障电子出行辅助产品的设计，使其能够满足视障者的出行使用需求。为了解决以上问题，本研究将其拆解为三个子研究问题，分别是子问题1：影响视障电子出行辅助产品使用的主要要素有哪些；子问题2：视觉障碍者与设计师之间在哪些主要要素的认知中存在差异；子问题3：在视障电子出行辅助产品的开发过程中设计师使用了哪些策略和方法来弥合差异，并推动产品落地。三个子问题在逻辑上层层推进，且上一问题都是下一问题的研究基础。 根据每个子研究问题的研究特征，使用混合研究方法对应进行了三个阶段的实证研究， 第一个阶段为案例研究阶段，主要是通过对典型视障电子出行辅助产品的案例研究，结合扎根理论的研究方法进行理论分析，用以理解影响视障电子出行辅助产品使用的关键要素及其相互之间的关系；第二个阶段为量化分析阶段，主要是使用感性工学的研究方法对视障被试和设计师被试进行量化数据收集和分析，进一步探索两者之间在影响产品使用的关键要素上的认知差异；第三个阶段为扎根理论研究阶段，主要是通过对资深设计师进行半结构式访谈和数据编码，构建视障电子出行辅助产品的设计方法模型，同时使用设计工作坊的形式对该理论模型进行了有效性验证。本研究基于设计学视角探索了视障电子出行辅助产品的设计方法和策略，为该领域研究中以技术为主导的研究和产品开发现状，提供了一个较为新颖的研究角度，在学科之内，本研究基于包容性设计中的能力需求理论提出了新的思考和发现。同时本研究还具有一定现实意义，即为当下视障电子出行辅助产品行业的设计实践提供了对应的理论支撑和指导方法。

Travel and mobility are indispensable activities in human life. At first glance, traveling may seem like a simple process of moving from one location to another. However, the complexity of this activity in reality far exceeds expectations. The act of traveling encompasses a multitude of influencing factors, including crucial stages of information capture and processing, all of which necessitate the assistance of visual faculties. For individuals with visual impairments, traveling poses a significant challenge. This thesis is conducted against this backdrop, employing bibliometric studies and historical research to analyze the modes of travel, technologies, and aids developed for visually impaired individuals, as well as to identify the hotspots in the literature pertaining to this domain. It reveals a gap in the research: a disconnection between the actual aids used by visually impaired individuals and the current development of electronic travel aids for the visually impaired. Concurrently, it posits a research question: how can designers intervene in the design of electronic travel aids for the visually impaired to ensure these products meet the users‘ mobility needs?To address the above problem, this study decomposes it into three sub-research questions: 1) What are the main factors influencing the use of electronic travel aids for the visually impaired? 2) Where do the differences in perception of these key factors lie between visually impaired users and designers? 3) What strategies and methods have designers employed in the development process of electronic travel aids for the visually impaired to bridge these differences and facilitate product implementation? These sub-questions logically progress and build upon each other, with each serving as the foundation for the next.Employing a mixed-methods research approach tailored to the unique characteristics of each sub-research question, this study is conducted in three empirical stages. The first stage, the case study phase, involves the analysis of typical cases of electronic travel aids for the visually impaired using grounded theory to understand the key factors affecting product use and their interrelations. The second stage, the quantitative analysis phase, employs kansei engineering to collect and analyze quantitative data from both visually impaired subjects and designer subjects to further explore the cognitive differences between the two groups regarding key factors affecting product use. The third stage, grounded in theory, involves semi-structured interviews with seasoned designers and data coding to construct a design method model for electronic travel aids for the visually impaired, validated through design workshops.This research explores the design methods and strategies for electronic travel aids for the visually impaired from a design studies perspective. It offers a novel research angle in a field traditionally dominated by technology-driven studies and product development, contributing new insights and findings to the theory of capability needs in inclusive design. Furthermore, this study holds practical significance, providing theoretical support and guiding methods for the design practice within the electronic travel aids industry for the visually impaired.
