Job Description
Missions
The PHARE project aims to investigate how humans perceive the animation quality of realistic virtual humans in virtual reality, through the lens of multimodal synchronisation in social behaviours and interactions. Using a multimodal dataset from pairs of actors (gaze, facial expressions, body movements and speech), the project will develop and then select a retargeting pipeline (transferring an animation to a model) to animate realistic virtual humans, and will investigate how controlled desynchronisation between modalities affects users' perception. During an immersive VR experiment, participants will observe virtual pairs whilst their performance on a resynchronisation task and their visual attention are measured. Subsequently, PHARE will assess the influence of behavioural fidelity by comparing these results (on high-quality animations) with those obtained on degraded or synthetic animations, thereby providing new insights and answers in the field of virtual social environment design.
Activity
The first phase (T0 to T0+3) will be devoted to developing the VR experience, in particular to implementing the desynchronisation system, optimising the rendering of high-fidelity virtual characters, and integrating correctly transferred animations with consistent lip-syncing aligned with the recorded voices. This phase also includes the construction of the experimental platform required for the collection of objective behavioural data.
In parallel, a series of pilot tests will be conducted to refine the platform, validate the technical pipeline and finalise the experimental protocol. Once the VR environment and the user synchronisation task have been stabilised (T0+4), the project will enter the experimental phase, during which participants will take part in our study, whilst we collect behavioural and performance data (T0+4 to T0+5).
Once data collection is complete, our final phase will consist of analysing our measurements, as well as preparing a scientific publication on these results (up to T0+6).
