HealthTas

The prototype

HealthTas is a team-designed wellbeing application prototype for University of Tasmania students experiencing stress, isolation, or anxiety. The interface was intended to feel private and approachable while still making urgent help easy to find.

My part of the project covered the visual theme, system modelling, and the Home, Help, and Calm Mode experiences. That included the daily check-in entry point and the accessibility controls used across the prototype.

Changes after testing

Early testing showed that the daily check-in card did not look actionable enough. The revised design gave “Take a Moment” a clearer place in the home hierarchy and treated it as a direct action instead of another passive card.

Continuous text-size sliders also made it difficult to predict the result of a change. They were replaced with S, M, L, and XL choices and an immediate preview. Help and crisis information remained available through a dedicated flow designed to work even when the rest of the application could not connect.

Evaluation

The moderated evaluation involved 12 UTAS participants. The Check-In to Calm Mode task and the accessibility-adjustment task each recorded a 91.7% completion rate. The revised check-in entry point was found immediately by 91.7% of participants, compared with no immediate discoveries in the initial pilot. The interface received a mean supportiveness rating of 6.0 out of 7.

This was a student usability evaluation and did not assess clinical effectiveness. HealthTas remained a design and testing project, not a live health service.
