Multiple technological aids have been proposed to support the social interactions of people with autism. The literature is extensive, but in many of the works there is a lack of clear processes focused on improving social skills. In this paper, we analyse a selection of 57 technological supports from the last 10 years, whose main characteristic is the quality and clarity of the design and evaluation processes. The objective is to provide the research community with a complete and interdisciplinary mapping of the main technological supports applied to social interaction, identifying the existing relationships between different axes of analysis: the psychological theories that support each approach, the types of technology used and the therapeutic models applied.
