Goals
- Test the usability of the data visualization tool with particular focus to readability, visual togetherness and instructional content.
- Gather student impressions of the tool.
- Identify problem areas and suggest feature enhancements.
Methods
Two iterations were prototyped with high-fidelity paper wireframes and tested using think-aloud tasks. A total of five University of Iowa student participated. Video and audio recordings were transcribed, and observations were detailed with recommendations across each iteration.
Low-fidelity wireframe for new "album" feature.
Deliverables
- New functionality, "album" to save and review, was added after observing students struggle to submit a report. The think-aloud gave us insights into how the students wanted the tool to work, and their expectations or needs to complete the task.
- The quick and robust data collected from the think-aloud task with high-fidelity wireframes provided 20 tool enhancements for developers and designers that were user-centric and evidence based.
- Readability and visual togetherness performed very well with minor recommendations which provided a needed morale boost to the stakeholders and developers.
- A full report with observations and recommendations as well as a presentation to stakeholders provided the team next steps for implementation of these two game interactions.
