With regards to the SUS the score of 77 in the initial study, above the 70 score, suggests of an overall high-usability score (Bangor et al., 2008) while in the second study is 64.38, slightly lower but also suggestive of an overall good usability score. This result is well backed up by the responses to the usability ad-hoc questions, which in the initial study the participants found the memory interface clearer to view and easier to use than the neutral score of 3, while in the second study the participants were divided in how easy the interface was to use. These results confirm our assumptions and expectations from RQ1.
