The aim of this paper is to examine which design guidelines and features can improve the acceptance of social robots as personal assistants for people in the German-speaking part of Switzerland. To answer this question, a design science approach was chosen. Based on a literature review of the current state of technology, an online survey was conducted in the German-speaking part of Switzerland. The results were analyzed using a quantitative content analysis. Based on the literature review and the survey results, a meta-model was created, illustrating various aspects and characteristics of social robot design. The findings indicate that the acceptance of social robots is influenced by human-like characteristics, although it should remain clear to users that they are interacting with a social robot.
