Interactivity in new media

Interactivity also relates to new media art technologies where humans and animals are able to interact with and change the course of an artwork. Artists and researchers around the world are working on unique interfaces to allow new forms of interaction that extend beyond the QWERTY keyboard and the now ubiquitous mouse. Artists, such as Stelarc work to define new interfaces that challenge our notion of what is possible when interacting with machines. His Hexapod for example looks like an insect though walks like a dog and the locomotion is controlled by shifting the body weight and turning the torso. Others like Ken Rinaldo have defined unique interfaces for fish in which Siamese Fighting Fish are able to control their rolling robotic fish bowls to interact across the gap of the glass. Simon Penny's Petit Mal allows a two wheeled sculpture to sense and respond to human presence and intelligently navigate the environment.

Denis McQuail mentions interactivity as one of the main characteristic of the new media. He quotes:

Interactivity: as indicated by the ratio of response or initiative on the part of the user to the "offer" of the source/sender
