Assessment of the usability of a digital learning technology prototype for monitoring intracranial pressure 1

View Article: PubMed Central - PubMed

ABSTRACT

Objective:: to assess the usability of a digital learning technology prototype as a new method for minimally invasive monitoring of intracranial pressure.

Method:: descriptive study using a quantitative approach on assessing the usability of a prototype based on Nielsen's ten heuristics. Four experts in the area of Human-Computer interaction participated in the study.

Results:: the evaluation delivered eight violated heuristics and 31 usability problems in the 32 screens of the prototype.

Conclusion:: the suggestions of the evaluators were critical for developing an intuitive, user-friendly interface and will be included in the final version of the digital learning technology.

No MeSH data available.

Mentions: This phase is done individually and participants may choose where they want to perform the evaluation. Each evaluator should run through and analyze his/her prototype at least twice. The first run is to make the evaluator familiar with the interface, while the second allows the evaluator to focus on specific elements in search of usability issues using Nielsen's Heuristics17, analyzing severity on a scale of zero (0) to four (4), where a higher score is associated with a larger usability problem (Figure 2).
