GR6: User Testing
Design
Final Design of Interface (screenshots)
Key design decisions and alternatives considered
as motivated by paper prototyping, heuristic evaluation, and user testing
Implementation
Internals and important design decisions.
Implementation problems that may have affected the usability of the interface
Evaluation
Setup
Users were found through personal contacts: architect, digital artist, art professor at School of the Museum of Fine Arts. They are representatives of our target populations.
We decided not to do a demo, not to bias the learnability of the interface.
Usability problems found and potential solutions
Both commenter and artist view:
- Poor contrast between pins and image
- Pins icons on comments
- Hard to see hashtags: could have them as blue links that are the filter
- Red border around annotation on the right looks like input field on error
Commenter review:
- Empty stars are not very visible
- Feedback/confirmation on deletion
- Change mouse marker to indicate draggable
- Expect double click to edit annotation
- Cannot close annotation window if you change your mind
Reflection
Learning through iterative design process.
Risk assessment, decisions about what features to prototype, and which prototype techniques to use, and how to evaluate the results of observations
