The computer vision interface allows multiple
visitors to participate simultaneously. It
provides real-time detection and tracking
of hands or hand-like motion. In conjunction
with the graphics and other system modules,
this generates the projected, luminous, gesture
traces. Pattern matching compares these user
drawings to human genomic calligraphic forms,
(human pictographs) which are displayed on
the vertical axis. A close match triggers
BLAST. |

|
| The
experience is responsive to the characteristics
of the movement of each visitor. The more
rapid one's motion, the more transient the
luminous traces and the slower the motion
the more sustained the luminous trace. This
helps establish an aesthetic of slowness leading
to a sense of presence and contemplation for
visitors. |

Homology is front-projected on to a
black projection surface. The overall width
and height of the installation are variable,
yet the piece has been projected to over 40-feet
wide and 12-feet tall. The images are presented
by five video projectors working with computer
workstations, servers and video cameras. |

Due
to the complexity of the system it was
implemented as a series of modules networked
together using Kolo, a multimedia authoring
platform under development at the UCLA
Hypermedia Studio. (Burke, 2002)
A state manager enables all the modules,
such as graphics, computer vision, basic
pattern matching and BLAST to work together. This
modularity also enables the pictographs
and BLAST visualization to be shown across
five displays. |
