The integration of virtual agents in real-time interactive virtual applications raises several challenges. The rendering of the movements of the virtual character in the virtual scene (locomotion of the character or rotation of its head) and the binaural rendering in 3D of the synthetic speech during these movements need to be spatially coordinated.(More)
This paper reports on the ACQA (Animated agent for Conversational Question Answering) project conducted at LIMSI. The aim is to design an expressive animated conversational agent (ACA) for conducting research along two main lines: 1/ perceptual experiments (eg perception of expressivity and 3D movements in both audio and visual channels): 2/ design of(More)
This paper reports on two new technical developments concerning sample environments for X-ray magnetic circular dichroism (XMCD). The first measurements under high pressures of up to 30 GPa are described. The difficulties of combining the techniques of high pressure and XMCD are commented on. The second development involves the use of a fast-switching(More)
