Assessments of novel assistive technologies for use in home-based services has been documented to be performed in a variety of ways and often with a rather narrow focus on safety and effect or effectiveness. In order better to understand the place for wider forms of assessments of assistive technologies, the current study presents a combination of the Ethical Matrix and the Socratic approach for assessment of health technologies—the Ethical HTA Matrix. This matrix was filled with content based on a case of a GPS localization system, which was validated by stakeholders. In a next step, central decision-makers in assistive technologies and stakeholders were interviewed concerning their views on this methodology. Mainly, the matrix was seen as very comprehensive, but too detailed with an abundance of information. Nevertheless, some informants suggested concrete uses of the matrix in their organizations. Some understood the matrix more as an epistemic tool aiming at providing an overview of the state of knowledge, while others identified a normative potential in the matrix that could be implemented in health innovation processes for the home-based services, in particular when discussing novel solutions and working methods with health professionals and care workers.
