Riko is very mobile because she has memorized her most frequented places and how to get there. Her friend told her about a new restaurant nearby, but she is uncomfortable going places she is not familiar with. She doesn't know enough about the trip, the crosswalks, and if the area is even walkable.
With this data the Spot app could create maps of walkable places based on aggregates of pedestrian activity.
San Diego had just installed lamposts with CityIQ sensors that could collect data about what was going on in the city, including pedestrian traffic.
Spot was designed specifically with the blind and visually impaired in mind, so it is completely accessible.
Riko uses Spot to find out if her destination is walkable, as well as if there are assistive technolgoies along the walk (such as audible crossing signals), and if there are any areas that might be temporarily unavailable (due to construction for example).
She is able to move more freely in her city, allowing her to visit more San Diego businessess, participate in her community and find a job.
