New Ultra-Sonic triggering to be added to my Laser Harp installation possibilities

I am going to be experimenting with another new to me technology, using ultrasonic sound field triggering, to trigger sounds and visual imagery.

This ultrasonic field can be set to trigger from 3 to 60 feet away, and different notes or sounds can be programed to change every few feet. It can also be programed to have a 'no action zone' of whatever size you wish, so that the trigger zone is across a room from the sending/ receiving device. The actual triggering is via moving through the 'field' of sent and reflected ultrasonic sound.The exact sounds and visuals triggered can depend on just how you move your body, arms and legs, and how fast. It was first developed to use with dancers.

It is also controlled, as is my OptiMusic midi controller and software, by a compact midi controller and software that runs on a laptop computer.

This technology could be used to create a sonic field of event/sound/visual triggering, around and before a museum patron even approaches the actual laser harp installation. this would add a deeper layer of experience to the children and adults who interact with an installation, as well as being an way to teach about both Lasers and Ultrasound.

I may seek to use it for the first time in my local Science Museum, Science Works, in a project for 2010.

But first I will buy a set up to experiment with in my Lab/ workshop! :-)
