Light x Sound invites adults and children alike to interact, play, and create with light. As participants enter the installation space they are presented with a series of coloured light pens and invited to draw, write, and trace to produce imagery and sound in physical space.

The principle is incredibly simple, mapping keys to pixels on screen which can be drawn at different sizes. It is immediately apparent how to use the interface, and as you use it more you can also improve dramatically.

Sonasphere is the brain child of Nao Tokui, and I have been involved with the identity, interface design and art direction. Check out the video for a 3 minute explanation of what Sonasphere can do, otherwise got to the Sonasphere website to download it, and have a go.

An installation version of Sonasphere was exhibited at ICC in Tokyo, in an exhibition called N_ext: New Generation of Media Artists from April 23rd, 2004 - June 27th, 2004. The main application interface is projected from above onto the floor and users who enter the projection area have their movements tracked and fed back into the application. Users can manipulate and interact with the environment by walking back and forward. Thus changing the makeup of the environment and moreover the audio output. User movement is tracked by a CCD video camera mounted above the projection area. Max/Msp patch for User Detection here.
