ABSTRACT
While taxies are widely considered as an easily accessible form of transportation to many, for the visually impaired, utilizing taxi services can be a significant challenge. In this paper we envision a system architecture where visually impaired people use GPS-enabled mobile computing devices to easily reserve and access taxi services. Specifically, as the first step in designing such a system, we try to understand the preferred interaction interface requirements of the visually impaired population using a set of interviews conducted over 28 visually impaired participants. Our results show that the smartphone usage rate of our interview participants is ~60%; thus, smartphone-based applications should not be considered as the "everyone-will-use-platform" when interacting with the visually impaired. Results from an extensive set of questions reveal that interaction interfaces in the form of key chains and wrist watches can also be effective for various interactive applications.
