Crop Circle Game
Gaming by Brainwave
The Crop Circle game was presented at the SIGGRAPH 2006 Annual Conference in Boston as part of the Education Venue. A simulation of one of the crop circles discovered near Stonehenge, England was designed to move backwards
and forwards on the Z-axis with a brain wave switch that measures peak values of brainwave amplitudes.
Brain switches also move individual spheres that comprise the crop circle formation up and down on the Y-axis. The object of this game is to be able to predetermine which sphere is moving where, and to animate individual spheres and the whole crop circle with brainwaves.
Brain Wave Audio Mixing
The crop circle game also uses audio to enhance the learning experience in the
environment. Several sound tracks were created for the game, one of which is a voice
over that provides information about the crop circle that was formed near Stonehenge,
England in 1996. Brain wave switches were assigned to mix individual audio tracks in
Apple's GarageBand application. Any sound application that includes the Audio Unit Lab
(AU Lab) application can be used with an IBVA4 plug-in that facilitates interaction with
the IBVA4 software and the sound application. In the crop circle game, switches are set
to control the audio gain of each track of a music composition that includes tracks of
brainwave music and alien sound effects. Switches can also be set to control filtering for
the audio tracks.
