Here is a close-up of the simulator
The objective was to pass as close as possible to the planet (intermittently visible in white). Here is a movie of one of the simulations
The development and experimentation of the software had started some months before at Essex and are still ongoing. Preliminary results on this line of research will appear in the Intelligent User Interfaces conference in March 2013 in a paper entitled "Towards Cooperative Brain-Computer Interfaces for Space Navigation".
Here is the abstract:
We explored the possibility of controlling a spacecraft simulator using an analogue Brain-Computer Interface (BCI) for 2-D pointer control. This is a difficult task, for which no previous attempt has been reported in the literature. Our system relies on an active display which produces event-related potentials (ERPs) in the user's brain. These are analysed in real-time to produce control vectors for the user interface. In tests, users of the simulator were told to pass as close as possible to the Sun. Performance was very promising, on average users managing to satisfy the simulation success criterion in 67.5% of the runs. Furthermore, to study the potential of a collaborative approach to spacecraft navigation, we developed BCIs where the system is controlled via the integration of the ERPs of two users. Performance analysis indicates that collaborative BCIs produce trajectories that are statistically significantly superior to those obtained by single users.
