HAL: a multimedia language for the creation of 3D animations of human figures

The design and development of a visual computer system for the modelling and simulation of human movements are described. A multimedia language named HAL (Human Animation Language) allows human figure movements to be generated in a graphical and intuitive way, accomplishing human-computer interaction through a 3D icon-graphic interface. In the language implementation, the object-oriented programming methodology is used. In order to validate the proposed language, a specific development environment, named "choreographic creation", has been designed. A PC system has been considered in order to provide better user accessibility.
