This paper presents verification data for a multimedia software application intended to enhance carers' ability to respond to everyday difficulties and emergency situations. The program provides educational information about first aid, how to deal with everyday problems and a number of emergency situations such as bleeding, falling and choking. An evaluation plan was developed, including instruments for measuring and assessing usability. These included a questionnaire, scenarios and a pro-forma for user trials; a questionnaire for evaluation of the program; log diaries, field notes and technical diaries. User trials were carried out with both healthcare professionals and family carers. Casual users were encouraged to test the programs at the professional sites. Users' views on usability were utilized for the development of further prototype of the software application.
