More Designer User Testing


This week… I went to an IRB info session and I GOT IRB APPROVAL! I can’t believe how quick the turnaround was. Private universities FTW!

Final of The Big 6

Built the final schematic meant to test PComp comprehension with Tom’s help and approval.

Questions/Answer Session with the IRB

Question: Would changing the location to the Andrew Heiskell Braille and Talking Book Library extend our approval timeline?

Answer: No, just let them know and provide a letter of cooperation.

Question: Would presenting my thesis live and having it live online has a video change my informed consent?

Answer: Might need to add an attribution statement to the consent form, “you can use my name or image in public presentations that will be available online.”

Krizia Tests the Big 6

Made Emily’s changes to the style guide and tested it again with Krizia. The designs can be seen side-by-side here, for comparison. These were done separately, at different times, and with no help from each other. Only the Workflow Guide was a reference.

Debriefing the usability testing:

  • Need to clarify that the red markings are meant to be removed
  • Ask the designer not to change the size of the artboard since it’s the size of the Swell Form Paper
  • Clarify that the graphic should be scaled up to fit the artboard
  • Since designers are visual, the directions should also live within the template itself

I updated the template with insights from testing with Krizia:
