| Abstract: | 根據統計，視覺障礙者之外出人口有逐年增長的趨勢，隨著步行需求的提高，友善的道路環境與適當的輔具工具是必要的。然而，無障礙引導設施無一定的規範且缺乏管理，因此造成視障者行走時危機重重。另一方面，視障者在外行走時須依賴定向行動訓練所學，運用視覺之外的感知來探索環境，除了使用白手杖維持平衡或藉由導盲犬引路之外，隨著智慧型手機的普及，行動裝置亦能成為獲得行路資訊的重要管道。雖然市面上已有許多導航應用服務，但大多為明眼人所設計，不僅無法提供視障者所需要的近身指引，其操作與訊息提示也與視障者習慣不相符。
本研究透過脈絡訪查、隨身觀察等質化研究方法進行使用者經驗研究，探討視障者於室外步行時的需求與面臨的問題。針對解決過馬路面向與直走於無追跡物區域等問題，本研究提出一藍芽穿戴式裝置GuidePin，由視障者佩戴於胸前並與智慧型手機連線，當行經佈建有Beacon的場域時，即可透過融入定向行動概念的提示訊息建構空間認知，搭配邏輯清楚的裝置操作策略，即時獲取近身資訊與修正提示並完成行走。經過迭代的原型設計與實際場域測試，本研究設計之導航服務可引導視障者外出行走、增加環境的熟悉與掌握度，讓視障者更自信且獨立地行走於城市中。
Today, we can freely travel to unfamiliar places and enjoy the convenience of navigation features on mobile devices. However most of the current apps are presented via visually-oriented interfaces, depriving visually impaired smartphone users of the benefit of this technology. Statistics shows that the visually impaired need to go out as frequently as those having sight, yet this tremendous demand for independence and mobility remains unsolved. Therefore, we present a new system called BlindNavi that integrates knowledge obtained from O&M training and the micro-location information of iBeacon to provide a point-to-point outdoor navigation system for the visually impaired. In order to free hands from holding smart phones while about town, we designed a GuidePin that can be wore on the front of the user’s attire to control their smartphone and provide the user’s current heading. Herein, we describe our iterative design process including lessons learned through qualitative research methods including contextual inquiry, shadowing, interviews with experts, and a discussion of our findings from the deployment of the app on test routes. Finally, the visually impaired are able to move about in the public domain independently with greater ease and confidence. |
