Indoor navigation systems must deal with absence of GPS signals, since they are only available in outdoor environments. Therefore, indoor systems have to rely upon other techniques for positioning users. Recently various indoor navigation systems have been designed and developed to help visually impaired people. In this paper an overview of some existing indoor navigation systems for visually impaired people are presented and they are compared from different perspectives. The evaluated techniques are ultrasonic systems, RFID-based solutions, computer vision aided navigation systems, ans smartphone-based applications.

Indoor Spaces

A number of visually impaired people suffer from navigation-related activities due to mishaps that discourage them from going out for social activities and interactions. In contrast to outdoors, traveling inside public spaces is a different story, as many environmental cues cannot be used and have their own set of difficulties. Some technologies have come into play in helping these people to have freedom in navigation (e.g., accessible map, indoor navigation systems, and wearable computing devices). However, technologies like accessible maps or indoor navigation systems are insufficient to fulfill the independent navigation gap as additional information is required (obstacles, barriers, and accessibility). To promote indoor navigation and create better use of technologies for visually impaired people, it is essential to understand the facts and actual problems that they experience, and what behaviors and strategies they use to overcome any problems; these are the concerns that led to this study. In all, 30 visually impaired people and 15 experts were recruited to give an interview about the behavior and strategies used to navigate indoor spaces, especially public spaces, for example, universities, hospitals, malls, museums, and airports. The findings from this study reveal that navigating inside buildings and public spaces full of unfamiliar features is too difficult to attempt the first time for a number of reasons, reducing their confidence in independent navigation.
