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.參考文獻 1. 衛生福利部統計處(2016)。身心障礙者人數。https://goo.gl/OZCXsx 特殊需求課程大綱(2004)。定向行動領域。教育部2. 張龍生(2003)。視障者步行環境之基礎研究。大同大學3. 顏杏砡(1992)。視障者空間認知與環境行為研究。東海大學4. 蘇怡帆(2012)。視障者在臺北市空間中的移動經驗。特殊教育學報 萬明美(2001)。視覺障礙教育,五南圖書出版股份有限公司。5. 黃耀榮(2012)。市區人行道視障引導設施之成效研究---以台北市現有人行道為 例。建築學報6. 兵界力(2000)。無障礙行人號誌使用者需求及控制績效評估之研究。中央警察大 學7. 黃耀榮等人(2008)。視障者特性、定向行動及引導研究。內政部建築研究所8.
