THE CRM DEVICE - A FORCE FEEDBACK GESTURAL TRANSDUCER TO REAL-TIME COMPUTER ANIMATION

Movements in images or sounds are naturally produced by physical objec ts under the action of forces. These forces can be natural, such as th ose produced by gravity, wind or turbulence, artificial, as produced b y manufactured motors, or human. Thus, to produce and control syntheti c movements, computer simulation of physical objects can be monitored by specific interfaces, which provide the simulation of force generato rs, or convey real human gestural intervents. In this paper, we focus on the last approach. An analysis of human gestures driving a physical object is presented together with a force feedback gestural transduce r we have developed, the CRM or modular retroactive keyboard. Finally, we show the computer context and paradigm in which we have developed this device, called the Instrumental Communication Interface (ICI).
