Transit apps for people with brain injury and other cognitive disabilities: the state of the art

Individuals with cognitive disability have difficulty using public transit, but little research is directed toward this issue. Recent studies suggest that smartphones may be useful assistive devices in this context. Current objectives were to (1) survey research into difficulties people with cognitive disabilities experience when using public transit, (2) survey the current state of the art of transit and personal navigation applications (apps) and features, (3) recommend best existing transit apps for people with cognitive disability, and (4) recommend the best designs and features of these apps to developers of future transit apps. Potentially useful features were found in four categories: Transit apps for (1) individuals with cognitive disabilities and (2) healthy individuals, and personal navigation apps for (3) individuals with cognitive disabilities and (4) healthy individuals. A total of 159 apps were examined, but only seven were found specific to public transit for cognitive disability. By comparing research recommendations and currently available features, we identified several unmet needs. We note that there appears to be a shortage of apps for this population-function but that there is good research in the area and it is well suited to inform app development.
