UCAT: Ubiquitous Context Awareness Tools for The Blind (1402.1324v1)

Abstract: Visually impaired people are often confronted with new environments and they find themselves face to face with an innumerous amount of difficulties when facing these environments. Having to surpass and deal with these difficulties that arise with their condition is something that we can help diminish. They are one sense down when trying to understand their surrounding environments and gather information about what is happening around them. Nowadays, mobile devices present significant computing and technological capacity which has been increasing to the point where it is very common for most people to have access to a device with Bluetooth, GPS, Wi-Fi, and both high processing and storage capacities. This allows us to think of applications that can do so much to help people with difficulties. In the particular case of blind people, the lack of visual information can be bypassed with other contextual information retrieved by their own personal devices. Our goal is to provide information to blind users, be able to give them information about the context that surrounds them. We wanted to provide the blind users with the tools to create information and be able to share this information between each other, information about people, locations or objects. Our approach was to split the project into a data and information gathering phase where we did our field search and interviewed and elaborated on how is the situation of environment perception for blind users, followed by a technical phase where we implement a system based on the first stage. Our results gathered from both the collecting phase and our implementing phase showed that there is potential to use these tools in the blind community and that they welcome the possibilities and horizons that it opens them.
