Demographic shifts and their consequences will lead to changes in the way health care is provided. Although assistive health-enabling technologies are regarded as one means to support these changes, they are minimally used, despite the maturity of the underlying technologies. This may partly be attributable to a disregard of users' needs and preferences. The aim of this article is to assess acceptance of health-enabling technologies with regard to their perceived usefulness, risks, and people's readiness to actually use them. Furthermore, we attempted to find out to whom individuals would entrust their health information, and what their basic fears are. We used a questionnaire presenting four exemplary technologies: emergency call systems, videophones, activity and health status monitoring. We conducted 147 face-to-face interviews and analyzed the results using descriptive statistics. Emergency call systems, health status and activity monitoring were rated as useful or very useful, videophones as hardly useful. Intrusion into one's privacy was the most prominent concern. Regarding fears in old age, people were mostly afraid of diseases and loss of independence. They would entrust their medical data to their physicians rather than relatives or caregivers. This study may contribute to systematic analyses of users' perceptions and preferences concerning assistive health-enabling technologies.
