Abstract

This research aims to evaluate a mobile phone-based video reminder system (MPVS) for people with dementia, with respect to its design and utility, in addition to its ability to satisfy user needs. Carers for those using the system use a bespoke desktop-based system to record and schedule reminders for delivery through the MPVS system. Nine participants were set eight activities of daily living (ADL) tasks and asked to repeat these tasks over a number of days within an ABA-evaluation protocol. In the A phase, ADLs were undertaken using standard reminding techniques; in the B phase, the MPVS system was used; following this, a second A phase was evaluated. ADL completion / compliance was rated and recorded by the carer. Carers and participants were interviewed prior to and following the evaluation to gauge their perceived needs and how these are met, in addition to the potential utility of the technology. The generalizability of the outcome of this evaluation is limited due to the low number of participants; however, the participants reported that the MPVS system assisted them to organize their routine, and the phone used to deliver the video messages was of a good size with adequate screen and audio clarity. The carers saw the potential utility of the technology, and although some had to learn how to use the desktop recording system, the wizard-led interface made it much easier to use for people with minimal computer experience.
