User Testing

Quantitative User Testing: Method Participants (n = 2) Procedure: Participants were instructed to complete 4 different scenarios using the paper prototype.

Scenarios included: 1) view glucose lab results; 2) Find more information on result outside the normal range lab result; 3) Contact a member of your care team; 4) Favorite test results Variables: Task Difficulty Satisfaction (1-3 Rating Scale) Aesthetics (1-3 Rating Scale)

User Testing: Results - 1st Iteration Quantitative Mean Satisfaction Rating (N=2)

Mean Aesthetics Rating (N=2)

2.7, SD = .59

2.4, SD = .50

Qualitative ● “No idea how to contact care team from home screen” ● “Vitals on home screen is confusing” ● Confusion with starred vs priority in the filter drop down menu

1st Iteration Solutions ● ● ● ● ● ●

Changed filter icon Clarified filter terminology Moved Med ID to its own widget and added care team to navigation menu bar Added dates to Lab Results Provided user feedback to the trending graph Provided contact button for any values outside of normal, salience differences

User Testing Round 2

User Testing Round 2 Results Participants (n = 2) Procedure: Participants were instructed to complete 4 different scenarios using the printed higher fidelity prototype. Scenarios included: 1) view glucose lab results; 2) Find more information on result outside the normal range lab result; 3) Contact a member of your care team; 4) Favorite test results Variables: Task Difficulty Satisfaction (1-3 Rating Scale) Aesthetics (1-3 Rating Scale)

User Testing: Results - 2nd Iteration Quantitative Mean Satisfaction Rating (N=2)

Mean Aesthetics Rating (N=2)

2.5, SD = .53

2.1, SD =.35

Qualitative ● ABC is a confusing label for a filter ● Button to contact doctor could be too much information ● Preferred as a filter option is still unclear (in part due to no prompt to set up preferred options is currently available) ● Icon to message Dr. is not clear

Redesign Iteration 3

If We Had More Time… ● More user testing ○ ○

Color coding Higher sample sizes (n = 15)

● More iterations of design ○

Iconography

● More in depth statistical analysis
