Objective.
The aim of the present study is to evaluate the usability of the telehealth system, coined Telekit, by using an iterative, mixed usability approach.
Materials and Methods.
Ten double experts participated in two heuristic evaluations (HE1, HE2), and 11 COPD patients attended two think-aloud tests.
The double experts identified usability violations and classified them into Jakob Nielsen’s heuristics.
These violations were then translated into measurable values on a scale of 0 to 4 indicating degree of severity.
In the think-aloud tests, COPD participants were invited to verbalise their thoughts.
Results.
The double experts identified 86 usability violations in HE1 and 101 usability violations in HE2.
The majority of the violations were rated in the 0–2 range.
The findings from the think-aloud tests resulted in 12 themes and associated examples regarding the usability of the Telekit system.
The use of the iterative, mixed usability approach produced both quantitative and qualitative results.
Conclusion.
The iterative, mixed usability approach yields a strong result owing to the high number of problems identified in the tests because the double experts and the COPD participants focus on different aspects of Telekit’s usability.
This trial is registered with Clinicaltrials.gov, NCT01984840, November 14, 2013.
