Light x Sound is a follow on work from Light Tracer created in collaboration with Japanese sound designer/performance artist Taeji Sawai, and was first exhibited in March 2009 at the Axis Gallery in Tokyo. 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.

TwelvePixels is a mobile phone interface which allows you to 'draw' using the twelve keys of the keypad. It was developed by Dr. Ivan Poupyrev and myself at the Sony CSL Interaction Laboratory and debuted at their Open House in June 2007. 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. For more information check out our research paper from CHI 2008, Pervasive 2010 or visit the TwelvePixels website. This project was developed at Sony CSL and is patent pending.

Light Tracer is an interactive installation which invites the user to write, draw and trace images in real physical space. A series of light sources are given to the user to manipulate, and are subsequently tracked by a camera and displayed onscreen. How the user uses the system is entirely up to them, however it is possible to write messages, draw pictures or trace physical objects such as your face or hand. Light Tracer has to date been exhibited in over 10 countries and was the recipient of the Tokyo Type Directors Club, Interactive Design Prize in 2007.

Sonasphere is an audio visual application for Mac OSX, which represents audio samples, effects and mixers as spherical objects within 3d space. These objects interact with each other in a generative way to produce interesting and complex audio visual results. 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, ...
