< prev next > A-1: The location of YCAM where this installation space exists. A-2 Changes in GPS: ID number and sensitivity (0-100dB) of each GPS that is in the sky above the installation site are indicated, and the moving direction of GPS is shown as the locus. (As the sensitivity turns stronger, light flashes brighter and the dynamics affecting the space becomes stronger, whereas lesser sensitivity causes slower, weaker flashes and gradual disappearance.)

fig.2 This is one result tested in the middle of the project. A record showed the path which the GPS satellite observed in Tokyo half a day passed through and follow the track. A route isn't straight, and seems to be like deformed, because we who are observed on the ground are moving as well as the GPS satellite. Our place is dynamic, and defines relatively.
