Brainloop: A brain-computer interface for Google Earth

The Brainloop brain-computer interface, demonstrated at the VisionSpace laboratory for perception and cognition at FH Joanneum, University of Applied Sciences in Austria.

Brainloop is an interactive performance platform that utilizes a Brain Computer Interface (BCI) system which allows a subject to operate devices merely by imagining specific motor commands. These mentally visualized commands may be seen as the rehearsal of a motor act without the overt motor output; a neural synapse occurs but the actual movement is blocked at the corticospinal level. Motor imagery such as "move left hand", "move right hand" or "move feet" become non-muscular communication and control signals that convey messages and commands to the external world. In Brainloop the performer is able - without physically moving - to investigate urban areas and rural landscapes as he globe-trots around virtual Google Earth. Through motor imagery, he selects locations, camera angles and positions and records these image sequences in a virtual world. In the second half of the performance, he plays back the sequence and uses Brainloop to compose a custom soundtrack by selecting, manipulating and re-locating audio recordings in real time into the physical space.
