Usability Testing Comes to a Close

Hello all,

We've just finished our second round of usability testing! It went better than we had hoped, and we have very high hopes
here at Access Lecture (Trademark pending. Don't steal it. It's mine).

The Testing:
This second round of testing focused primarily on receiving feedback with regards to the app's new features. New features included:
  • Zooming buttons (in addition to the pinch-gesture)
  • A revamped note-taking system
  • The ability to save notes to the iPad
  • A settings page (including toolbar preferences and scroll/zoom options)
  • New icons
Additionally, we were finally able to demonstrate a working proof-of-concept. Instead of showing pre-made/sample lecture images on the iPad, we were able to actually transmit our own whiteboard notes in real-time!

Test subjects were given a set of tasks to perform and give feedback on:
  • Following along with and taking notes on three sample, real-time lectures.
  • Adjusting the app's settings.
  • Exploring the new note-taking system.
  • Identifying the new icons.
After completing these tasks, additional, quantitative feedback was collected via a post-test interview.

Results:
While feedback in certain areas in the initial round of testing were a bit scattered, the feedback for round 2 tended to be nearly universal.

Here are some of the key conclusions which we have made about the app, based on user feedback from the latest round of testing:
  1. The new icons were solid. 100% of participants found the icons intuitive and easy to see.
  2. The new zooming buttons were generally considered to be intuitive, although many preferred using the pinch-to-zoom method exclusively.
  3. Although the idea behind the new note-taking system was praised, the implementation needs a lot of reworking. This was expected, as this feature is still very much a work in progress.
  4. 90% of participants would find Access Lecture helpful in a real course.
  5. The settings need fine-tuning, but are on the right track.
Next Steps:
Work on integrating the feedback from the usability tests is already well underway. We have analyzed and prioritized the feedback, and have many of the high-priority fixes either implemented or near completion.

What remains to be done is to continue our brainstorming of an appropriate note-taking system. Participants did not want a still-image to write on, and would have preferred being able to both write and scroll on the actual lecture screen. This poses a significant usability challenge: how does one support useful and intuitive note-taking on-top of a real-time image stream? We are all excited to start brainstorming solutions!

Oh yeah, we hear back from ASSETS '11 in 8 days.
