Exploring the usability of a videophone mock-up for persons with dementia and their significant others

Persons with dementia might have considerable difficulties in using an ordinary telephone. Being able to use the telephone can be very important in order to maintain their social network, getting stimulation and for reaching help when needed. Therefore, persons with dementia might need an easy-to-use videophone to prevent social isolation and to feel safe and independent. This study reports the evaluation of the usability of a touch-screen videophone mock-up for persons with dementia and their significant others.

Four persons with dementia and their significant others tested the videophone mock-up at a living laboratory. In order to gain knowledge of the participants' with dementia ability to use their own computers and telephones, interviews and observations were conducted.

Overall, the participants had a very positive attitude towards the videophone. The participants with dementia perceived that it was useful, enjoyable and easy to use, although they initially had difficulties in understanding how to handle some functions, thus indicating that the design needs to be further developed to be more intuitive.

The findings suggest that the videophone has the potential to enable telephone calls without assistance and add quality in communication.
