Abstract

Dementia is a chronic brain disease affecting cognitive functioning. People with dementia have a higher risk of getting lost. In recent years GPS based technology has been utilised to locate lost persons with dementia. We interviewed six families using such technology focusing on perceived usability, user-friendliness and usefulness. The informants also completed the QUEST 2.0 questionnaire which measures satisfaction with assistive technology. By and large the informants found the equipment easy to use, and it was viewed by all as being very useful. There were a number of usability issues which adversely affected usage, e.g. system stability, secure fastening, size, user interface issues and varying GPS-reception. The QUEST 2.0 results corresponded with the findings in the interviews. Further usability studies, as well as R&D to address issues such as security and privacy protection and use in the public health sector are needed.
