In response to your question regarding the "electronic dance floor" I
am submitting the following.
As a result of my collaborative efforts with composer Russell Pinkston.
The floor was designed to accommodate my wish to provide the dancers
with a greater input in the creative process while in performance. (In
this case interact in real time with the composer via the application
of pressure or weight sharing with different parts of the floor)
The floor is capable of transmitting precise position coordinates,
velocity and pressure information in the form of standard MIDI. The
surface consists of a large number of Force Sensing Resistors (FSRs)
which are attached to heavy duty plastic sheeting and covered with
polyethylene foam. The sheets may either be placed on top of or beneath
a standard Rosco Dance floor. The FSRs are typically arranged in a grid
with 16 columns (left to right) and 4 rows (front to back) which
results in a 16' square dance surface with 64 1' x 4' velocity and
pressure sensitive regions, each of which is assigned a separate input
channel of a Voltage to MIDI Interface Box which has 64 analog inputs,
plus MIDI Out. The MIDI Box incorporates a Motorola MC68HC11
microprocessor and can be programmed to convert input/output analog
signals to/from any desired MIDI messages, on multiple MIDI channels.
Composer Russell Pinkston and myself had created (to date) three works
utilizing the floor, as well as present the floor in various
conferences around the world. I am hoping to have an opportunity to
present the floor at the next Dance & Technology Conference.
I hope this information is helpful.
Best Regards, Yacov.....
