碩士 / 國立臺南大學 / 特殊教育學系碩士在職專班 / 106 / The purpose of this study was to investigate the difficulties and strategies encountered by visually impaired adults in unfamiliar indoor environments and to explorer quick response code (QR code) feasibility designs. For the purpose, one questionnaire based on two times of interview including users’ opinions was conducted. Participants were aged from 18 to 60, and all were smart phone users, 40 valid questionnaires were collected for statistical analysis. The conclusions were as follows:
1. In an unfamiliar environment, participants always asked service counter or relatives for orientation, and often walk using a white cane or move under the guidance of others. When planning a route in an unfamiliar environment, participants couldn't understand the information or no one could ask was the most troublesome. Moreover, facing complicated routes or no one could help was the knotty problems they faced while moving.
2. Presentation about the content of the environmental information, participants trended to present in text by using smart phone voice system (voiceover & talkback), and would combine with navigation interface.
3. QR code could detect through infrared detector nearby elevator or stairs, the pre-recorded voice would be played by the sensor when someone entered sensing area. Participants showed QR code priority setting places were train station and high speed rail station.
4. In addition, opinions showed significant differences between educational levels and visual deterioration ages.
For visually impaired adults, there are many O&M challenges and limitations in an unfamiliar environment. Based on the findings summarized above, government regulation (such as Building Act), rewards programs, and industry-academic cooperation might encourage and up-grade indoor navigation and QR code designs for visually impaired adults.
