Activity reports

Introduction

The objective of the i3D research team is to contribute to making interaction in virtual worlds as simple and intuitive as in the real world.

To this end, three research axes are privileged:

Interaction metaphors and paradigms

Haptic feedbacks force or tactile feedback

Human factors study

Within these research axes, focus is put on:

Spatial approaches: spatial input and output.

Immersive environments: immersion of the user into the virtual world or immersion of the application into the user's real world.

Better exploitation of the user's various sensory channelssuch as visual and haptic.

The research activities are based on both the "Workbench"and "Video See-through HMDs". These systems have been chosen for their complementarity and their potentials in terms of interaction and their adequacy to the main approaches mentioned above (see ).

Research of the i3D group is organized around three themes:

The study of interaction metaphors and paradigms. Tasks apparently as simple as displacement inside a virtual scene or catching and repositioning an object are still difficult to realize in a virtual world today. The objective of this theme is to study new paradigms and metaphors of interaction using the approaches quoted above.

The study of haptic feedbacks. There are several ways to return a haptic feedback: active haptic feedback(requiring the use of a haptic feedback device), pseudo-haptic feedback, , passive haptic feedback(makes use of a prop), and sensory substitution. The objective of this theme is to study these different approaches in order to have a better characterization of haptic feedback according to the completed task.

Human factors study. In addition to the two previous themes, the research group aims at carrying out experiments whenever possible. These experiments are either carried out to provide a basis for the research, such as psychophysics experiments on human perception or the evaluation of existing techniques and peripherals, or the evaluation of approaches developed by the group.

The i3D group wishes to emphasize the genericity of the proposed solutions. The solutions are developed with the objective to integrate them into various applications within different application fields. However, concerning applications, the group currently focuses on the most promising applications in terms of industrial use for the Workbench:

Interactive exploration of complex datasuch as data from scientific computation, fractal models or meshes.

Virtual prototyping: virtual prototyping for industries such as automotive or aeronautic.
