Create virtual objects that seem real to the eye, touch and ear

Humans move around and experience the real world by exploiting all the senses at their disposal, such as vision, touch and hearing. Indeed, real objects respond to human interaction in multi-sensory ways: resisting touch, moving, changing shape, making noise. Thus, virtual environments should also provide such correlated information for the different senses, and be both realistic and interactive. This first lesson will introduce recent developments, due to his laboratory and others, aimed at creating multisensory virtual worlds using graphical, haptic and auditory outputs. He will describe decisive changes in terms of hardware, as well as new algorithms for the interactive simulation of contact between man and the physical environment. In addition to applications in video games and cinema, these developments will enable us to study realistically how people interact with their environment.
