This is part six in my series about the Human-Computer Interaction course I took through Coursera. Read all my posts for the full story.
Assignment 5 Ready for Testing
Goal of prototype
The goal of the mobile app is to simplify vehicle maintenance tracking. Specifically, this prototype focuses on the procedure for entering mileage at the time of filling up the fuel tank.
Before moving forward on our high-fidelity prototypes we needed to enumerate the issues found during the heuristic evaluations. Some examples:
Heuristic
Issue
Location
Severity
user control
settings options missing
settings page
3
error prevention
"That's correct" button on mileage confirmation page is in same place as "ignore" button on first page
bottom menu
2
visibility of system status
After clicking "That's correct" button it's not clear what happened to the data and how the information will be used in the future
gas pump confirmation page
2
Based on these issues we identified the changes needed:
Issue
Where
Change Needed
settings options missing
settings page
brainstorm settings needed and add to settings page
"That's correct" button on mileage confirmation page is in same place as "ignore" button on first page
bottom menu
change contents of bottom menu and move action buttons to middle of screen as appropriate
after clicking "That's correct" button it's not clear what happened to the data and how the information will be used in the future
gas pump confirmation page
add status indicators: "saving to mileage log" and "checking for maintenance due"
We added these issues to our development plan and continued to add functionality and improve our prototypes with these changes in mind.
Next up would be user testing so we also developed a user evaluation plan outlining details such as what we wanted to learn from the user testing, who our participants would be, what would happen during the test, and what we would measure.
By the end of this assignment our high fidelity prototypes had complete interactivity and were ready for user testing.
