Investigating Novel BCI Displays that Support Personalised Engagement and Interpersonal Connections

DREAM 2.2 is an immersive art installation that gives form to our mind's ephemeral data. Participants wear an EEG headset and use their neural activity to alter visuals that are projection-mapped, in real-time, onto an explorable maze in an exhibition space. Their neural data also influences interactive audio. Audiences wear an EEG headset and help shape the installation audio-visuals, or they can explore the exhibition maze and be immersed in audio-visuals that are being shaped by another person's neural data. This case study investigates ways of personalising Brain-Computer Interface (BCI) displays so that people can feel a closer connection to their neural data. It also provides insights into how BCIs can support novel interpersonal engagement.
