The document summarizes the first day of an AUX bootcamp. Participants learned about the design thinking process and product design sprints. They were split into groups and guided through an exercise where they interviewed each other about wallet usage, developed personas, and sketched wallet prototypes addressing an identified problem. The document outlines the typical 5 day product design sprint process of understanding the problem on day 1, diverging with ideas on day 2, deciding on a solution on day 3, prototyping on day 4, and validating with user tests on day 5.
