A 3D interface to explore and manipulate multi-scale virtual scenes using the leap motion controller

Gesture-based interaction models can be efficient and simpler to understand if designed to correspond to common user interactions with the physical world. This paper presents a 3D interface and its implementation to quickly perform navigation and manipulation tasks in multi-scale and multi-resolution 3D scenes using a low-cost consumer sensor: the Leap Motion controller. The developed system has the goal of exploring the potential of accurate hands and fingers tracking alongside mid-air 3D gestures, to investigate specific design advantages and issues they present in such complex environments.
