According to the statistics of the international NGO “World Blind Union”, there are approximately 285 million people who are blind or partially sighted globally. Besides, the statistics of Taiwan’s Ministry of Health and Welfare reported that the number of the visually impaired persons kept growing in this decade, and therefore how to assist them to have better experiences in their daily lives will be an important topic. In this study, the researcher investigated how iBeacon positioning technology assisted the visually impaired to move by themselves indoors; in addition, the researcher had designed and constructed a prototype of guidance system to allow them to know their positions and further it could guide them to arrive at their destinations. This system combined smart phones, iBeacon positioning technology and wearable devices to guide them in indoor environments; besides, the linkage of the internet and caregivers (such as administrators of indoor environments or their relatives/friends) could make them feel more relieved by themselves in unfamiliar indoor environments and also could allow caregivers to understand their conditions. In this study, the SUMI questionnaire suitable for assessing a system prototype was used to understand the subjects’ feedbacks in their usage. The results indicated that voice prompts could effectively help users in the system operation and the guiding process; besides, they had positive feedbacks on the dimension of learnability in the system evaluation. Moreover, the feedbacks of the dimension of global system satisfaction also showed that this prototype system had satisfied their needs and also promoted their confidence as they walked independently indoors.
