1. For the user observation with think-aloud, comment on how you experienced the technique (as either user, observer or other). What kinds of information and insights did it give you about the usability of the prototype? What aspects of the technique worked well or were frustrating?

 

I was away for this exercise but I did conduct a think-aloud user test for the Design Thinking Part 2 Assessment. This provided valuable insight, with certain users explaining their difficulties with certain aspects of the design which could only have been observed if they stated their thoughts out loud, particularly their frustrations with the taking down details that the prototype provided for them. It highlighted and issue with our design which we had to improve.

Certain users didn’t say enough and had to be reminded to think-aloud, overall though it seems like an easy way to get more information out of user testing and it is easy to experiment with having a “silent” user test and think-aloud user test with multiple users and comparing the advantages and disadvantages of each.

 

2. For the heuristic evaluation, what kinds of information or insights did you gain about the usability of the prototype? What aspects of the technique worked well or were frustrating?

Heuristic evaluation was very suited to our design. The heuristics made sure our design followed basic user needs. In the description for each block we made sure the options were described in terms that were familiar to the user rather than system-oriented data. Error prevention was became a consideration with the possibility of users placing blocks to enter their data in the wrong way.

Heuristic evaluation is something that is very is to undertake to test a design in its early stages, a limitation is the limited perspective of the process.
