USABILITY EVALUATION (DESIGN-ORIENTED & METRIC-ORIENTED): Patients, caregivers, and clinical care/support professionals in each type of evaluation undergo a 60-minute one-on-one session in which they are assigned tasks to complete using the system, and an observer records how the tasks are completed. Participants are also requested to talk aloud while performing the task. Participants in the metric-oriented evaluation respond to usability and usefulness questionnaires.
