3D interaction techniques using gestures recognition in virtual environment

In virtual and augmented reality (VR/AR), the interaction is used to designate a set of rules and techniques that allows the user to perform interaction tasks in a virtual/augmented environment. The use of hand gestures is the most natural way to perform an interaction, for this reason gestures recognition has a part in the word of interaction. In this context, the aim is to study the different interaction techniques that are used to interact with 3D objects in the case of virtual/augmented reality and the different methods for vision based hand gesture recognition. In this paper we develop a 3D interaction technique “selection/manipulation” using gestures recognition in virtual environment, the choice of the interaction technique and the method of gesture recognition are explained. This implemented system provides more flexible, natural and intuitive interaction possibilities, and also offers an economic and practical way of interaction.
