Titre de la présentation :
Conceiving 3D User Interfaces
Résumé :
Designing or implementing virtual reality (VR) applications require to
address several issues like immersion, 3D visualization, handling of
multiple input and output devices, complex dialogue design, etc. The
growing number of devices available makes the design space of
interaction techniques very large. As for multimodal applications, when
implementing VR applications, developers usually have to address hard
to tackle issues such as parallelism of actions, actions sequencing or
synchronization, fusion of information gathered from different input
devices, combination or separation of information (fission mechanism)
to be directed to different devices. These issues make modeling and
implementation of VR systems very complex mainly because it is
difficult to describe and model how such different input events are
connected to the application.
This talk is intended to present the process of developing and
validating 3D interaction techniques, addressing the selection of
devices, the specification of interaction through the use of formalism,
implementation issues and validation. We start reviewing basic concepts
of virtual reality, with special attention to 3D interaction
techniques. Then, the whole process of designing a 3D interactive
technique is thoroughly analyzed. Our on-going work on the development
of new interaction techniques and devices will also be addressed.
