Brainloop: Functional Advanced Brain Interfacing System

From their website:

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 subject, Markus Rapp, 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 and manipulating audio recordings in real time, as sound designer Brane Zorman re-locates them (5.1 surround) into the physical space. The virtual reality environment is stereographically projected allowing the audience to perceive the events in 3D.

This work results from a multi-year collaboration between Slovenian media artists and Austrian scientists. Its author is the Slovenian media artist Davide Grassi, which in the past has been focusing on similar topics realizing the project Brainscore – incorporeal communication together with the artist Darij Kreuh. Responsible for the BCI application is Reinhold Scherer from the BCI-Lab of the TUG.

7. Background of the project

The project Brainloop evolves from the projects Brainscore – Incorporeal communication

Brainscore – incorporeal communication is a performance for two operators, which act in a virtual reality environment through their avatars. This performance attempts to avoid completely physical participation of operators in the management of avatars. The task is achieved by triggering command on a console through a system based on operator’s brain waves signals and an eye movement tracking system. The aim of the performance is to create a controlled flow of information, in terms of audio-visual messages, in order to establish a primitive form of communication between the two performers as well as between them and the audience.
