3D interaction and tangible interfaces

Propose solutions for smooth transitions between different levels of mixed reality (2D <=> AR <=> VR)
Propose interaction techniques that enable interaction at different levels of the mixed reality continuum
Specify and model MR perceptual peculiarities in relation to interaction
Explore the fusion of tangible interfaces with virtual and augmented reality to create immersive, intuitive, user-friendly or natural user experiences
Leverage the use of tangible interfaces to interact with digital twins to propose methods for modeling, simulating and interacting with complex or industrial systems

Identify and visualize informative indicators of 3D interaction quality
Develop natural interaction techniques adapted to different interaction contexts (e.g. 2D/3D or VR/AR)
Determine the right 3D interaction metaphors to use, depending on the context of use
Enable users to make smooth transitions between the different levels of mixed reality (2D <=> AR <=> VR)
Manage the diversity of interaction devices and modalities
Establish natural "real-time" interaction between a digital environment and a user by recognizing the latter's activity from all types of sensors (cameras, ambient, wearable, etc.)
Offer interactions integrating several senses (sight, touch, hearing) to move towards multi-sensory immersive user experiences
Create tangible interfaces that can be deformed or adapted to changing usage contexts or user needs
