The light effects controller
creates visual effects that can be used for various applications,
including concerts, discotheques, variety shows, and presentations.
As opposed to preprogrammed or manually/sound-controlled
lighting systems, a novel approach for the generation
of visual effects is proposed. The participants' movements
are used to create visual effects in a developed system.
The Doppler effect on ultrasound frequency is used for
obtaining information about participants' movement. The
controller performs Doppler frequency spectrum analysis
to determine the participants' speed and rhythm of movement,
and then creates corresponding visual effects.
For
data exchange and remote control, the full galvanic isolated
RS-485 interface under DMX protocol is implemented. This
interface type is commonly used for controlling various
lighting systems in entertainment, concert, and theater
systems.
The
controller can be used easily to modernize existing lighting
systems, because the several most popular load types are
supported as well. The device can be controlled remotely
via a standard lighting system RS-485 interface or can
serve as the master for controlling existing lighting
equipment, which allows a rapid retrofit of existing systems
with minimal cost and time.
