Personas + User Testing with a Designer

Revised Personas


  • Remove Gender
  • Reference to watching TV
  • Age doesn’t matter, remove
  • Remove Educational Level
  • Make the names bigger
Persona of Jo, ITP grad student, sighted and is a tactile learner
Persona of Eric who is blind and an accessibility professional
Persona of Amanda, an undergrad engineering student

Emily Tests the Big 6

Emily’s and mine, respectively, for comparison. These were done separately, at different times, and with no help from each other. One of the six is missing as I was still trying to track it down. Only the Workflow Guide was a reference.

Emily Lin User Feedback

I user-tested with Emily Lin on 2/17/19. I gave her the style guide and the untouched SVGs, without showing her mine, and had her go through the work flow. Here’s an audio recording of her feedback.

Her itemized feedback for the style guide:

  • Didn’t understand the context of component pins as lines rather than dots
  • How do you know when to use capital letters?
  • Unsure if she could scale the graphic
  • Wasn’t sure how much she could move the template text
  • Need to explain how SVGs, when saved, separate text boxes into two separate lines of text
  • Wasn’t sure if she should delete “Label 1” after using it
  • She wasn’t sure if she should save and separate the key and graphic into two separate files
  • She wasn’t sure about best practices for arrows, need info on them and leader lines
  • Need to include the Braille character for ohm
  • She didn’t know if she should label the Arduino
  • Need an excerpt that you can put grey labels under or near the Braille, but the Braille should always be the closest thing to the element
  • Wanted visual examples of which lines to thicken
  • Wanted a visual margin
  • She wasn’t sure if/when she should include a key

Feedback from DesignWeek Parkour

Anne-Laure and Heidi brought up a great point that doing the testing at the Tandon DesignLab would bring about a sense of confidence when our participants walk in through the doors. Because it’s a university, it establishes a legitimacy and is contextually relevant because it’s an engineering school.

To get the word out, I can ask to send out an email blast from the department head and Cherisha Agarwal ( might be able to help with that.

It also brings up a point for thesis that ITP and Tandon need a central, accessible hub like the Stanford D School.

Tactile Graphics Catalogue

I created a catalogue of all of the Phys Comp schematics, in order of the classes (i.e. complexity), with columns for link on the site, the reference number I created, and the status. The labs/schematics start at class 2, so all graphics start with a “2”.

Style Guide Updates

The Style Guide is being refined and is a WIP. Emily’s feedback needs to be addressed. I also incorporated feedback from Amy, which is itemized here:

  1. Present style guide with more structure (bullets and headings) and move out of paragraph form to make it more skim-able.
  2. Use headers, make a table of contents, and possibly a list of figures (still thinking on figures list).
  3. Introduce and describe the tactile graphics standard, summarize some of the main suggestions in the “Why Tactile?” section.
  4. Think about including a glossary for components- maybe not to define their technical function but at least show the library of symbols.
    1. Tom mentioned linking to the PComp site glossary here for the reader’s reference.
  5. Rethink where I put the components measurements chart
  6. For Design Standard 3, show side-by-side figures of “clarity” and “clutter”
  7. For Design Standard 2, define design standards and explains how to set them, and what starting values you think make sense.
  8. When first mentioning Braille, link user to intro article on Braille.
  9. Show an image of the template to explain what a double slash mark and title are.
  10. Include an overview on tactile graphics techniques and why you focused on swell paper. Link to an external resource.
  11. Explain “leading” in regards to Braille.
  12. Put that there should be one graphic per page in the design standards.
  13. Recommend a Braille for readers to use.
  14. Number all the design standards.
  15. Split the printing sections into two: Supplies and Running the Machine.
  16. Link out to all the brands of Swell Form Machines.
