This article presents a global overview of the results of the evaluation activities performed in the European project Immersive Accessibility (ImAc), which investigated how access services can be integrated into 360º videos. More specifically, the paper presents the methodological approach in ImAc testing, and reports on the results of the evaluation activities on the tools (a subtitling editor, an audio description editor, a sign language editor, and an accessibility content manager), on the media player, and on the access services (subtitling, audio description, audio subtitling, and sign language interpreting).
