To validate a personalized routing technique with wheelchair users, understand their route choices and acquire their feedback on the necessity of wheelchair navigation and the importance of personalized routes.
A routing technique using a weighting method, called Absolute Restriction Method (ARM), was employed to compute personalized routes based on users' routing preferences. The evaluation involves five manual wheelchair users. The study protocol consists of three sessions: pre-activity, activity and post-activity sessions. The evaluation included a comparison between personalized routes and shortest feasible routes, in terms of route characteristics and users' ratings of important parameters.
Subjects travelled a 14.64% longer distance along the personalized routes than the shortest feasible routes. However, all personalized routes had better path quality (slope and surface condition) than the shortest feasible routes. Four out of five subjects rated the parameters they deemed most important higher for the personalized route than for the shortest feasible route.
The study confirmed that the shortest route criterion is not always suitable for individuals with mobility impairments. Personalized routes that take into account individual characteristics, route preferences and environmental characteristics are a promising solution to lessen the difficulties that manual wheelchair users face when navigating unfamiliar environments.
Wheelchair users indicate the importance of personalized routes for individuals with mobility impairments. In regard to evaluation results, although subjects travelled 14.64% more distances in average along the personalized routes than the shortest feasible routes, they rated the personalized routes better path quality and less effort to travel.
验证一种针对轮椅使用者的个性化路径规划技术，了解他们的路径选择，并获取他们对轮椅导航必要性和个性化路径重要性的反馈。
采用一种名为绝对限制法（ARM）的加权方法的路径规划技术，根据用户的路径偏好计算个性化路径。评估涉及五名手动轮椅使用者。研究方案包括三个阶段：活动前、活动中和活动后阶段。评估包括在路径特征和用户对重要参数的评分方面，对个性化路径和最短可行路径进行比较。
与最短可行路径相比，受试者沿着个性化路径行进的距离长14.64%。然而，所有个性化路径的路径质量（坡度和路面状况）都优于最短可行路径。五名受试者中有四名认为他们认为最重要的参数在个性化路径上的评分高于最短可行路径。
该研究证实，最短路径标准并不总是适用于行动不便的个体。考虑个体特征、路径偏好和环境特征的个性化路径是一种有前景的解决方案，可减轻手动轮椅使用者在不熟悉环境中导航时面临的困难。
轮椅使用者指出了个性化路径对行动不便个体的重要性。关于评估结果，尽管受试者沿着个性化路径行进的平均距离比最短可行路径多14.64%，但他们认为个性化路径的路径质量更好，行进更省力。
