Abstract: This study addresses the usability of the Applied Robotics for Installations and Base Operations (ARIBO) Autonomous Warrior Transport On-base (AWTO) rider reservation and reminder system mobile application, called ARIBO Mobile. ARIBO is an on-demand transportation system that will allow Soldiers to reserve a vehicle for a specified time and at predefined pick-up and drop-off locations throughout the medical campus at Ft Bragg, North Carolina. The mobile application allows riders to request transport reservations, modify or view existing reservations, and receive reminders for upcoming reservations. A usability assessment was conducted with 7 subject matter experts to provide a heuristic evaluation of the application, feedback on the design of the application, and an objective assessment of the tool. Direct measurements including time to complete task, number of steps to complete task, errors, and requests for assistance were recorded. The usability assessment of ARIBO Mobile provides the designers with feedback that may be used to update or change the design prior to wide distribution to the Soldiers.
