Altered States of Consciousness in Human-Computer Interaction: A Review

There has been increasing interest shown in experiences such as lucid dreams, hallucinations, or awe that arise in HCI. Altered States of Consciousness (ASC) is the umbrella term for these experiences, yet it has been subject to fragmented study, and design knowledge to help individuals working on technology-driven ASCs is lacking. This paper investigates HCI studies involving ASC artefacts through a scoping review. The findings relate to (1) ASC induction methods, (2) ASC experiences through artefacts, (3) ASC artefacts, and (4) the technology of ASC artefacts. The returned literature shows that HCI studies have mainly explored psychologically induced ASCs, and XR technologies and embodied interaction are widely used in ASC research. Meanwhile, physical artefact design including active body movements and the integration of games and play approaches featured as prospective directions. These results will contribute to the knowledge of those studying and designing ASC artefacts.
