Table 3 Selection of measures for improving usability.
From: Qualitative and quantitative evaluation of the usability of transport ventilators using eye tracking
Measure | Effect on usability | Example |
|---|---|---|
Complete labeling and identification of items | Visual attention, direct access | Labelling of inspiratory and expiratory connection at device and tubing system |
Clear labeling/clear user guidance | Reduced confusion | ‘Press rotary knob’ instead of ‘Press button’ |
Direct access to important functionality | Fast approach to tasks solving | Hard keys for setting peak pressure instead peak pressure set via upper limit of the respective alarm |
Consistent labeling | Facilitated training, reduced cognitive workload | PSV instead SPONT/CPAP + ASB |
Meet expectation/convention | General intuitivity | On-switch on the right side instead on left side |
Decent logo | Reduced distraction |
