The
performer is represented on the console by an icon positioned
at the centre of the display. The commands at his disposal are
placed around this icon. By activating the Scroll command at Level
1 of the first phase, a strip with the five continents appears.
The performer selects the continent he intends to visit. |
|
|
|
MODE 1 / Level 2:
Select Continent's Area |
|
|
 |
|
Consequently,
Google Earth's virtual camera moves to that continent and on the
performer's console appears the Level 2 panel with the Scroll
Bar containing portions of the selected continent, e.g.: Northern,
Central, Southern, Western and Eastern Africa. |
|
|
|
MODE 1 / Level 3: Select Country |
|
|
 |
|
At
Level 3 the actual country is selected. Besides the three main
commands (Scroll, Select and Back) there are two more, Show Borders/Hide
Borders and Show Cities/Hide Cities, which are activated by combining
the motor imagery of the feet with that of the left or right hand. |
|
|
|
MODE 1 / Level 4: Operating Camera |
|
|
 |
|
The
Scroll Bar at Level 4 contains commands for the virtual camera,
namely Scan, Move, Pan, Tilt and Zoom. The thought of movement
of the right or left hand defines whether the camera will move
to the right or to the left respectively (in the case Scan or
Pan has been selected), forward or backwards (if Move has been
selected) and up or down (if the command activating the Camera
Tilt has been selected). |

CHANGE MODE |

When
the system has gathered a sufficient amount of data, we move to
the second phase of the performance, during which Google Earth
locations investigated earlier are re-presented, while the performer
uses Brainloop to compose a custom soundtrack by selecting and
manipulating audio recordings in real time, which sound designer
Brane Zorman re-locates (5.1 surround) into the physical space.
|
|
|
|
MODE 2 / Level 1: (De)Activating Tracks |
|
|
 |
|
For
that purpose, 9 soundtracks appear on the performer's console.
Four are beat-based, four are ambient sounds and one, indicated
as Local, contains sounds, loops and samples related to the continent
or country that GE is showing at a given moment. |
|
|
|
MODE 2 / Level 2: Adjusting Effects/Parameters |
|
|
 |
|
Brainloop
enables the performer to apply to the selected sounds either various
effects (Reverb, Equalisation Frequency, Chorus, Delay and Pitch
Shift) if a beat-based track has been activated, or various parameters
(Modulation, Oscillation, Wave Mix, Low Frequency Modulation,
Filter Attack) if an ambient track has been activated. |
