Personalized Trip Planner for Seniors (PTPS)

The Personalized Trip Planner for Seniors (PTPS) will create an interactive voice agent for this portion of the population that has limited possession of smartphones. The agent will give directions to any given destination with options of the means of transportation that can be used. It is intended to first become a deployed tool for Pittsburgh, but created in a flexible manner that allows it to be adapted for any other city. The research team will use reinforcement learning and neural network technology to model what seniors really say. The team will also address three fundamental issues for people as they age: (1) we process information more slowly as we age, so PTPS will find ways to slow down the agents speech, while keeping it intelligible; (2) we cannot attend to several things at the same time, so PTPS will get the users attention before giving out any important information; and (3) we do not retain much information at a given time, so PTPS will only give one piece of information at a time and will repeat the essential words at the end of the message. The project will take two years to reach deployment stage. In Y1 the agent will be built with the help of partners, AARP and Age Friendly Greater Pittsburgh. In Y2, the agent will be refined and endowed with personalization, tested and deployed. Results of PTPS will be measured in several ways, the most important being if the team can get real people to use it, give positive feedback on it and, especially, to become return users.
