Brain Computer Interface: The design of an invisible interface. This is the title of my theoretical diploma thesis. The thesis deals with the technology of BCIs, its origins in the history of neuroprostheses and the current shift from medical to commercial applications. The findings are applied to the concept of interface and its meaning in the context of BCIs. New challenges as well as opportunities for design arise.
In the main chapter, the human brain is compared with a computer in order to be able to better define the individual parts of the acronym BCIs. This is preceded by a comparison of the anatomy of the brain and the construction of the computer. The performance analysis is followed by various theories, such as the Turning Theory, Searl‘s Chinese Room or the Theory of Action. In addition, the discussion focuses on specific characteristics, such as neuronal plasticity or the socialisability of brains. The interview with Nelson Steinmezt - Head of Design at NextMind, currently one of the leading companies in the field of commercial BCI - helps to better understand the task of the interface, which is to mediate between brain and computer.
