Background: Welfare technology aids can enable frail elderly people to age in place and are therefore important to develop. Applications for mobile security alarms are an example to create security in activities, especially outside the home, which contributes to engagement in the society. However, it is unclear how frail elderly people look at these aids. Objective: The purpose of the study was to describe activities of frail elderly people outside their own homes and their attitudes related to the potential future use of mobile security alarms in these activities. Method: A survey was conducted in a geriatric department (n=47). Analyses, including group comparisons, were conducted by Chi-Test (χ2) and Mann Whitney U-Test. Result: The number of activities outside the home a regular week was low ( = 3) and the participants abstained from these activities because they were insecure (n=21), alone when they went out (n=30) or felt unease (n=27). Lonely living and women engaged significant lower in activities outside their home compared with cohabitants’ and men. Conclusion: Several participants considered that the application would increase their activities outside their own home and the participants generally had a positive attitude related to the future use of mobile security alarm applications.
