Final answer:
After interviewing gym patrons, the UX designer should analyze the interview data to understand user needs. This will pave the way for brainstorming sessions to generate creative solutions, followed by selecting a concept to develop into wireframes and prototypes for testing.
Step-by-step explanation:
After conducting interviews during the empathy phase of the design thinking process, a UX designer has gathered insightful data about the gym patrons. The next step in the process is to analyze the data collected to gain a deeper understanding of the users' needs, experiences, and pain points. This analysis will inform the ideation phase where the UX designer and their team can conduct a brainstorming session to generate a range of creative ideas and solutions to address the users' needs.
Once a collection of ideas is generated, the team can then select a design concept and use the defined requirements and constraints to evaluate these ideas. After a critical evaluation, the selected idea(s) can be turned into wireframes and prototypes, which materialize the concept into a tangible form that can be iteratively tested and refined with the target audience through usability testing.
