User-centred iterative design of a smartwatch system supporting spontaneous reminiscence therapy for people living with dementia.

Reminiscence therapy is beneficial for improving the quality of life for older adults living with dementia. However, it is difficult for caregivers in care homes to make this part of their daily practice because remembering a resident's individual stories is difficult. Proximity-aware technologies can make rapid connections between residents, their histories, and nearby artefacts.

A longitudinal study of usability in health care: does time heal?

We report from a longitudinal laboratory-based usability evaluation of a health care information system. The purpose of the study was to inquire into the nature of usability problems experienced by novice and expert users, and to see to what extend usability problems of a health care information system may or may not disappear over time, as the nurses get more familiar with it-if time heals poor design? As our method for studying this, we conducted a longitudinal study with two key studies. A usability evaluation was conducted with novice users when an electronic patient record system was being deployed in a large hospital.

A longitudinal study of usability in health care - does time heal?

We report from a longitudinal laboratory-based usability evaluation of a health care information system. A usability evaluation was conducted with novice users when an electronic patient record system was being deployed in a large hospital. After the nurses had used the system in their daily work for 15 months, we repeated the evaluation.
