Steadily increasing numbers of older people and people in need of care represent critical challenges for today's society. In the last years, diverse (health-related) technologies have been developed to facilitate living at home for older people but also to support (professional) care personnel in their daily care efforts. Ambient Assisted Living (AAL) technologies have the potential to enhance safety, support medical therapy, or facilitate everyday chores and social life. With the huge range and variety of technical opportunities, the question arises what influences (potential) users' decisions for the right technology in their individual conditions and situations. In particular with regard to the fragility of the care situation, it is unknown which technologies are desired for different care needs and diverse situations.
