This section consists of a review of the three technologies used in Brain-Mediated Immersive Music Production (BIMP): brain-computer interfaces (BCIs), 3D audio, and smart contact lenses. The review looks at the current state of these technologies, exploring their concept, functionality, affordances, current limitations, and challenges. This serves as a foundation for understanding the concepts of MP2072, which will be explained on the next page (MP2072).
Brain–computer interfaces (BCI), also known as brain-machine interfaces, are devices that enable users to interact with computers through brain-activity. BCI acquire brain signals, analyze them, and translate them into commands that are relayed to output devices that carry out desired actions (Shih et al., 2012).
3D audio (three-dimensional audio) refers to the phenomenon of transforming sound waves to place them virtually anywhere in an auditory 3D space, hence replicating the behaviours of natural sound waves. It creates an immersive experience in which sounds appear to be coming from the front, sides, rear and above areas (Parsons, 2022)
Smart contact lenses are wearable computer lenses that are used on the eyeball surface to add information to what the wearer sees. This technology is designed to offer an augmented reality (AR) experience through the lens, which uses a tiny microLED display the size of a grain of sand to share information, as well as smart sensors powered by solid-state built-in batteries (Mojo Vision 2022).
