Abstract : Virtual reality is a technology with applications in numerous fields (medical, automotive, etc.). This thesis focuses on immersive virtual spaces, and aims at studying the effects of the two major types of interfaces proposed (6 degree of freedom flystick, and finger-tracking system) on the user experience, and specifically for 3D object manipulation. We are interested in parameters such as ease of use, sense of presence, speed and precision offered. To do so, we design experiments to evaluate these parameters via tasks with measurable success, and which are not field specific.In a first experiment, we study complex general purpose tasks, combining skills required in everyday manipulations, such as grabbing, releasing, translating, rotating, and balancing objects while walking. We then refine our study by observing the effects of those interfaces on the movements themselves, by decomposing them into individual and grouped degrees of freedom. Lastly, we evaluate the applicability of our direct manipulation system in the context of a preliminary study on the use of virtual reality for the treatment of Alzheimer’s disease. These studies analyze the properties of these interfaces to provide guidelines to the choice of the most appropriate interface for future experiments.
