Propositions for a mid-air interactions system using leap-motion for a collaborative omnidirectional immersive environment

Abstract

This paper describes a work in progress that exploring the potential of Leap-Motion acquisition system as a believable alternative to multi-touch device to interact with a large curve display: Hyve-3D immersive environment. This system could be used for collaborative ideation with local people working together in the same area and multiple Hyve-3Ds can be connected (via Internet) to share a single work space. Today, Hyve-3D uses a new paradigm of 3D interaction based on tactile device tracked in 6 Degree Of Freedom and it is possible to make immersive sketching with a tactile tablet. We believe that systems of Mid-Air gestures can be an important asset for carrying out, more simply, naturally some tasks. We believe that Leap Motion device must be, not an alternative but an additional solution. This paper proposes a classification of interactions and a distribution by devices. We will define a grammar of gestures and we will offer some technical solutions.
