PhD Thesis proposal
Post-doctoral position proposal
In the framework of the European research project ULTIMATE (Eureka
project #1493), a post-doctoral position is offered in Paris, France
for a period of one year starting January 2004.
ULTIMATE is a new high-performance driving simulator developed by
a consortium of industrial and academic partners : RENAULT (Guyancourt,
France), SEOS Ltd. (Burgess Hill, UK), REXROTH-HYDRAUDYNE (Boxtel,
the Netherlands) and CNRS-LPPA (Paris, France). The simulator prototype
is now under construction in RENAULT Technocentre, and will be operational
from June 2003. This simulator combines two main features :
- a large-amplitude motion cueing system, based on large rails rendering
in both X and Y directions, plus a 6-degrees-of-freedom hexapod system
for rotations ;
- an on-board immersive display system, switchable between a projection
display with curved screen, and a stereoscopic head-mounted-display
with very large field-of-view and very low weight.
The objectives of the Eureka research project include an experimental
study of the perception-related issues involved when driving this
simulator. This study is to be conducted on the ULTIMATE prototype
by CNRS-LPPA (Laboratory of Physiology of Perception and Action,
Collège de France) with the collaboration of the post-doctoral
fellow. The domain of research for that study includes :
- evaluating the effects of combined linear vection and acceleration
;
- analyzing the effects of combined visuo-vestibular cues in curves
;
- measuring perceived distances in the HMD, and the influence of
motion parallax ;
- optimizing motion cueing algorithms to elicit realistic motion
perception ;
- analyzing driver behavior in typical basic driving situations (braking,
turns, etc.) with regards to motion perception factors.
The further definition of the experimental protocols chosen among
these research areas will be done in collaboration with the different
project partners in order to optimally combine fundamental and applied
objectives.
The position proposed to applicants with a PhD in the field of Cognitive
Sciences, Neurosciences, Experimental Psychology, etc., with a strong
interest in :
- experimental psychophysics ;
- multi-sensory motion perception ;
- computer interfaces ;
- driver behavior modeling.
Although programming skills are not necessary to use the simulator
as an experimental tool, some proficiency with computer interfaces
is preferable to set up the experiments with the development teams.

Post-doctoral CLARESCO proposal
Within the framework of the European project CLARESCO, the Laboratory
of Physiology of Perception and Action (CNRS- Collège de
France), Paris, has a post doctorate position available for a year
starting in the fall of 2003 for a perceptual evaluation of new
advanced car lighting strategies.
Project overview :
The CLARESCO project aims at improving traffic safety at night through
the evaluation of innovative lighting technologies dedicated to truck
and car driving. The evaluation framework that will be developed
in this context will allow the analysis of human perception and behavior
in terms of safety, efficiency and comfort according to the driving
environment such as traffic conditions.
New Intelligent lighting technologies may prevent accidents by illuminating
road turns, cyclists and pedestrians, among other things. However
the effect of advanced lighting systems on traffic safety, driver
comfort and perception has not been estimated yet through a unified
methodology. CLARESCO project will develop a comprehensive framework
to analyze, assess and predict implications of a range of future
lighting systems.
In order to estimate the contribution of such a technology, the
proposed work consist of detecting potential physiological and/or
behavioral changes that might occur while using adaptive car lighting
strategies in night time driving by using simulation tools. Then
evaluate if those changes produce a decrease in both safety and comfort
while car driving at night.
For that goal, distance perception and gaze orientation mechanisms
will be studied in different driving situations (with specific attention
on curve driving). A detection of the conflicts existing between
the direction of the lighting and specific body mechanisms (such
as eye and head motion) will be achieved.
The position proposed to applicants with a PhD in the field of Cognitive
Sciences, Neurosciences, Experimental Psychology, etc., with a strong
interest in:
- Visual psychophysics;
- Multi-sensory perception;
- Computer interfaces;
- Driver behavior modeling.
An application should include a letter describing the applicant's
graduate training and research interests, a CV and sample publications.

Traffic thesis
PhD Thesis proposal
Description
The Technical Centre for Simulation of Renault has been developing
and using driving simulators for more than ten years. These simulators
are used for vehicle design studies (ergonomics studies, accident
analysis, design of new intelligent components in a car, validation
of lightning…). The software that runs those simulators, named
SCANeR, has been developed by Renault, and is made up of several
modules, for instance a visualisation module, a sound generator,
a vehicle dynamics model and a traffic generator. SCANeR is commercialised
since 1995, and users include the University of Minnesota, the Transport
Research Laboratory, the Pennsylvania Transportation Institute, the
Fraunhofer-Institut, Renault and Nissan among others.
In those simulators, the driver is placed within a virtual world,
and the traffic around the driven vehicle is of uttermost importance.
The requirements of a traffic generator are twofold: each virtual
vehicles should drive realistically around the vehicle driven by
the subject, and it should be possible to control those vehicles
to reproduce a specific traffic situation required for an experiment.
In the approach taken at Renault, each vehicle is an agent that
is made up of different parts: perception of its environment, simplified
mechanics model, control level (following a trajectory), tactical
level (deciding to override) and strategy (where do I want to go).
Each vehicle can be ordered to take specific actions by a scripting
language.
The subject of the thesis is first to define a new software architecture
that will allow agents to interact with each other and a high level
scripting language. Then one agent (or even better a set of agents)
that simulates a vehicle will have to be designed. This thesis
will take place during the development of a new major release of
SCANeR,
and thus important modifications of the existing mechanism are
to be envisioned.
Some directions of research might be:
- State of the art of AI techniques, especially for the driver
behaviour (fuzzy logic, neural networks, hierarchical state machines…);
- De-correlate the different sub-models that make up an agent,
and thus enable the user to create a new agent by combining those
sub-models;
- Study the collaboration of different models (designed independently)
within the same scene;
- Improve the perception of realism of the traffic through the
disparity of driving behaviour;
- Develop the co-operative behaviour / interactions of drivers
(in many crossroads situations, a strict application of the regulations
lead to a deadlock, that can only be resolved by co-operation between
the drivers)
- Improve the level of control from the scripting language on the
driven vehicles
This thesis will take place as a co-operation between Renault and
the Applied Mathematics Centre (CMA) of the École des Mines
de Paris.
Profile
The expected profile for this thesis is a background in computer
science, and centres of interest in AI, robotics, automatic control
engineering…
This three years work will start in autumn 2003.
