Objectives and Approach

GLAD-IN-ART deals with the development of a human-computer interface system conceived for the active control of manipulative procedures represented in computer-generated virtual environments. The interaction device will be an instrumented glove, worn by the human operator and capable of recording the hand's geometrical configuration in the control space.

The morphology of such an interface device allows the operator to control the motions of the represented virtual objects in a more natural way without the displacement constraints of current interaction devices such as joy-sticks or handballs.

A basic characteristic of the GLAD-IN-ART system is the management of components devoted to replicate kinesthetic force and internal grasping force feedback on the user's wrists and hands espectively. This greately improves the sensation of reality felt by the user during manipulative procedures.

Inside a 3-D control space, the pose of the human operator's wrist is recognised by a purposely developed vision system. The set of video cameras, shooting from fixed locations the user's hand/arm configuration, acquires information which can also be processed in order to implement the concept of gesture interface: the human operator sends commands to the software application by performing appropriate hand/arm gestures.

The system is actually an integrated set of sub-systems that can be used individually or together in a multiplicity of combinations depending on the nature of the application.

Exploitation

Identified applications of the GLAD-IN-ART system include rempote-controlled operations in space and hostile environments, surgical simulations, physiotherapy and robotics.
