In this paper we investigate the influence of the integration and separation of the Degrees Of Freedom (DOF) on the users' performances during 3-D orientation tasks. For this purpose, we compare the performances and the level of DOF's coordination users reached using two interaction techniques, one integrating and the other separating the task's DOF. To(More)
We developed a free form deformation application for an immersive environment in which users can interact freely using data gloves. To ensure better comfort and performances, we added the possibility of bi-manual interaction in our environment. To investigate the actual gain obtained by this interaction technique we designed an experimental protocol based(More)
The use of Touch Screen Interaction (TSI) for 3-D interaction entails both the addition of new haptic cues and the separation of the manipulation of the Degrees of Freedom (DoF) of the task: a 3 DoF task must be transformed into a 2-D+1-D task to be completed using a touch screen. In this paper, we investigate the impact of these two factors in the context(More)
A major challenge in understanding the cuprate superconductors is to clarify the nature of the fundamental electronic correlations that lead to the pseudogap phenomenon. Here we use ultrashort light pulses to prepare a non-thermal distribution of excitations and capture novel properties that are hidden at equilibrium. Using a broadband (0.5-2 eV) probe, we(More)
We present a new Virtual Reality (VR) interaction technique, called Cursor On Surface (CrOS). It is an interaction technique for cursor manipulation on 2-manifolds using touch screen input. The objective is to provide a technique to easily perform complex modelling operations in VR. CrOS is based on an algorithm which maps 2-D inputs into cursor(More)
In the underdoped copper-oxides, high-temperature superconductivity condenses from a nonconventional metallic "pseudogap" phase that exhibits a variety of non-Fermi liquid properties. Recently, it has become clear that a charge density wave (CDW) phase exists within the pseudogap regime. This CDW coexists and competes with superconductivity (SC) below the(More)
In this paper we present a new interaction technique based on degrees of freedom (DoF) decomposition for accurate positioning in virtual reality environments. This technique (called DIOD for <i>Decomposition and Integration Of Degrees of freedom</i>) is based on an adaptation of the Two-Component Model. It provides two different control levels regarding DoF(More)
À paraître in : Synergies de pays germanophones 7/2014. Cette étude se propose d'analyser l'influence de l'interaction 3-D sur l'apprentissage d'une langue étrangère à partir d'une expérimentation menée auprès d'apprenants d'allemand langue étrangère. Les résultats doivent permettre de réfléchir à l'intégration de ce facteur technologique dans un scénario(More)
