About Gaggle

Premiered at the Open House Festival of the 23rd BCS conference on Human Computer Interaction in Cambridge, UK.

The Gaggle prototype has been imagined, designed and developed in order to experiment personally with such interfaces, and primarily with the link between sensor (in this case 'pings'), physical computing board (in this case Arduino) and SuperCollider audio language.

The Gaggle Project (Richard Hoadley) has been supported by Anglia Ruskin University Digital Performance Laboratory, the ARCDigital, and CoDE.

Gaggle provides an opportunity to investigate performance using Gaggle, including questions such as:

  • Does the number of sensors affect the nature of the interface? Does increasing the number of sensors to a point where they are difficult to control consciously affect performativity?
  • Does the relative position of the sensors affect the result. In particular these ultrasound sensors can interfere with each other, especially when designing for movement such as that created by dancers.
  • How does the type of movement to be used with the interface affect the use and design of the interface? For instance, in this case, how is the direction of the sensors affected and what difference does this make?
  • Interplay between physical implementation and software algorithms: for instance, does the physical nature of the interface need to be reflected in its performance results. Of course all the usual issues concerning algorithmic composition and structuring arise at this point.
  • ...and many more...

Beautifully and inspiringly danced by Jane Turner's dancers. More information at janeturner.net.

We are in the process of investigating further new developments in the links between dance, movement and music.
