Contexte et atouts du poste
This PhD position is framed under the EU H2020 ICT 25 PRESENT project. PRESENT aims at creating virtual digital companions -- embodied agents -- that look entirely naturalistic, demonstrate emotional sensitivity, can establish meaningful dialogue, add sense to the experience, and act as trustworthy guardians and guides in the interfaces for AR, VR and more traditional forms of media. There is no higher quality interaction than the human experience when we use all our senses together with language and cognition to understand our surroundings and, above all, to interact with other people. We interact with today's "Intelligent Personal Assistants" primarily by voice. However, communication is episodic, based on a request-response model; the user does not see the assistant, which cannot take advantage of visual and emotional clues or evolve over time. Nonetheless, advances in the real-time creation of photorealistic computer-generated characters, coupled with emotion recognition and behaviour, and natural language technologies, allow us to envisage virtual agents that are realistic in both looks and behaviour; that can interact with users through vision, sound, touch and movement as they navigate rich and complex environments; converse in a natural manner; respond to moods and emotional states; and evolve in response to user behaviour.
This international partnership includes the Oscar-winning VFX company Framestore; technology developers Brainstorm, Cubic Motion and IKinema; Europe’s largest certification authority InfoCert; research groups from Universitat Pompeu Fabra, Universität Augsburg, Inria, and the pioneers of immersive virtual reality performance CREW.
The PhD candidate will join the Inria's Rainbow team (https://team.inria.fr/rainbow), internationally recognized in the robotics, virtual reality, and haptics research fields. Currently, the team is composed by more than 30 members working in topics related to human-computer interaction, physical simulation, virtual reality, haptics, and visual servoing.
The PhD candidate will also have access to unique experimental platforms Immersia and Immermove which offer a high-tech set-up to perform user experiments in real and virtual environments and measure motion (motion capture, EMG, force plate, eye trackers).
The general objective of the PhD is to create interactive characters endowed with levels of behavioural sensitivity and responsiveness for Virtual Reality applications. By populating virtual environments with such characters, our goal is to achieve new levels of immersive experiences, by reinforcing the feeling of presence through non-verbal communication between a user and one or more agents.
We will investigate situations involving 1-to-n interactions between a user and multiple (virtual) characters. In such scenarios, the first step will be to define the full list of events or user actions that agents should be reacting to. This will be done by also detailing the virtual sensory channels by which agents perceive actions or events, e.g., if we want agents to react to a loud sound, a flashlight, or after being touched by the user.
We will also establish a list of expressive motions and emotions agents will be able to perform, defining their vocabulary for non-verbal communication (NVC) capabilities, such as expressing: annoyance, impatience, anger, fear, etc. These motions and emotions will be formulated on a set of variables to modulate their level, and make them dependent on the triggering source, such as the position of the user, the location of an event in the environment, or the state of the neighbouring agents to simulate emotion propagation phenomena.
We will explore motion capture data edition techniques that offer a good trade-off between the naturalness of motion and performance. However, pre-recorded motions are not sufficient since the reactive motions are depending on the features (location in the environment, level, etc.) of the user actions or events that triggered it.
In addition to motion, which will be conveyed through visual sensory channels to the user, we will also explore the tactile sensory channel to render the environment (and, more importantly, the contacts made between the user and the characters) to the user with two objectives in mind: make the user aware of physical contacts (that will affect user behaviours, e.g., to avoid collisions) and convey voluntary NVC messages to the user (e.g., shoulder tapping). In this respect, this raises several issues, which the task will study such as: the type of haptic rendering devices we will use, their number and location on user bodies (in the case of wearable haptic devices) and the contact rendering technique.
The candidate should also be comfortable with as much following items as possible: Experience in computer graphics, physical simulation, haptics, and animation; Experience in 3D/VR applications (e.g., Unity3D); Experience in carrying out principled user studies; Good knowledge of programming languages and tools (e.g., C#, git); Good spoken and written English; Good communication skills. This PhD is framed under a larger project, thus the candidate will have to interact with other members of the project and assist to the project meetings.
