But when the visually impaired people are moving into an unknown and unfamiliar territory or staying in a complicated public environment, they often get lost easily or they may even put themselves in danger. Most of public facilities designed especially for the blind and visually impaired people have been constructed immovably and passively, so whenever the visually impaired people are trying to find the direction by means of tactile floor tiles or static tactual maps, under this circumstance, it would cost them a great deal of time and strength, and hence, it would make them to feel anxious and frustrated time to time. Thus, this study utilizes the smart phones carried and commonly used by many visually impaired people as a platform to be operated along with RFID technology, and this study also probes into various combination patterns of voice and vibration, and in addition, parameters adopted in this study were related to several types of points of interests (POI) (e.g. bus stop board, intersection and bus stop board ; intersection, bus stop board and landmark) in addition to the alert modes for a mobile phone (e.g. audio alert, vibration prompt after audio alert, vibration prompt-pushing a button-audio alerting); and whereby, the present study will survey the usage performance (e.g. number of errors, time taken to complete the task and frequency of call-for-help) and conduct a subjective evaluation of consumer’s satisfaction along with the One-way ANOVA Analysis, and afterward, the difference between various data sets of significant items will be tested using the LSD Post-hoc Test. The research results showed that best performance was achieved while both the stop board and signpost and landmark were available in terms of types of points of interests and density allocation; and the optimal feedback mode for the mobile phone was to activate the audio alerting mode together with vibration mode, and moreover, based on an analysis of subjective evaluation, it was found that one of the most preferable alert modes selected by visually impaired people was vibration prompt-pushing a button-audio alerting. These research results can contribute to a better designing of mobile guide devices to allow the visually impaired people be able to quickly and intuitively find their locations and directions when they go out and hence it not only can reduce the risk of accidents happened while they are wandering at intersections, but also it will be able to effectively promote the use of barrier-free public spaces by enhancing the willingness of visually impaired and blind people to go out alone.
