This project from ESA/POLSA aims to assess whether the collection of neural activity data via near-infrared spectroscopy (fNIRS) can be used to establish a human-computer interface in microgravity. The study will collect neural activity and questionnaire data before, during, and after flight. The outcomes from this project could contribute to thedevelopment of advanced technologies on future exploration missions and also provide insights for Earth-based biomedical applications of human-computer interfaces, such as neurotechnology for rehabilitation and assistive devices.
