Redesigned the user flow based on usability heuristics. Designed hi-fi wireframes and a design system.
Usability Evaluation
What was not followed: Recognition Rather than Recall: Instead of being able to select previously saved patient details, users had to fill this in.
"Don’t be UI literal: Don’t show app UI if users haven't experienced it yet. Show the user benefit first.
You may display education about the specific UI in a later context."- Material Design Guidelines. This was exactly the case in the existing app.
Usability Evaluation
Bottom navigations should not have more than five destinations, as per Material Design. There were seven destinations in the existing app.
What was not followed: Flexibility and Efficiency of Use:There were over 53 filters. There was no search available for these. Only 6 filters were visible at a time.
What was not followed: User Control and Freedom:While the default view showed "all doctors", the user could not return to this view after selecting a filter.
User Testing and Ergonomics
Based on user testing with the initial wireframes, it was observed that 8/15 users wanted to search first, and 7 of them needed to stretch their fingers in order to reach the search bar. It was for this reason that it
was repositioned. 6a showcases the thumb zones with the initial wireframes that were made. 6b was the updated design.
