Within the ANR « DEVISE » project (https://anr.fr/Projet-ANR-20-CE19-0018, https://devise.inria.fr), the recruited candidate will investigate the behaviour and the perceptual performance of low vision patients immersed in a Virtual Reality (VR) platform implemented in a VR headset. This software platform called « PTVR » (Perception Toolbox for Virtual Reality) has been developped by our research group over the last 2/3 years (https://ptvr.inria.fr).
The goals of these experiments will be :
a/ To measure experimentally the ability of patients to interact with a VR environment thanks to their hand, head or gaze.
b/ To validate experimentally novel visual rehabilitation techniques and innovative visual aids all based on VR and allowing patients to have an individualized assistance to improve their visual perception. This individualization will rely on retinal imagery exams with patients (microperimetry).
c/ To test experimentally serious games allowing patients to use with pleasure and comfort the technologies previously validated in b/.
In parallel with these studies, a key mission will be to disseminate our main results and developed tools in different ways : scientific publications, conferences, edition of our web sites, presentation of our VR low vision simulators to the large public and organisation of meetings with low vision associations and health staff in the domain of ophthalmology.


Main activities of the recruited candidate will be :
- Finalise the design of the experiments described in the ANR DEVISE project. The methods used by the researcher will be in the framework of experimental methods and questionnaire studies. Two main types of experiments will be performed : a/ experiments in which low vision persons will perform visuo-motor tasks (sometimes presented as serious games) while seating and wearing a VR headset ; b/ microperimetry exams aiming at quantify the visual field characteristics of each patient (scotoma size, etc.).
- Collect experimental data with low vision patients.
- Analyse experimental data with open-source Rstudio software.
- Design control or complementary experiments that would not have been anticipated in the initial project and that would be induced by experimental results.
- Supervise students (depending on demands) who will assit the recruited candidate in the activities of this project.
- Participate in the writing of scientific papers and reports corresponding to experimental results
- Participate in the updating of our web sites (https://devise.inria.fr/ et https://ptvr.inria.fr/).
- Publish data in national et european open source repositories (notably HAL).
- Participate in national or international workshops and conferences to present our results.
- Participate in collaborative meetings of the DEVISE project notably to improve the open-source « PTVR » software developed by our consortium to perform the planned VR experiments.
- Create and modify python scripts from our PTVR software to improve its behaviour, its userfriendliness, and its promotion towards researchers of our field and towards healthcare personal in the domain of ophthalmology.
- Participate in the organisation of a workshop toward the end of the project to disseminate results toward the general public (thanks to a VR low vision simulator) and in the organisation of information meetings with patients associations.


- Ph.D in the field of Vision behavioural neuroscience (less than 4 years ago).
- At least two international publications as first author and linked to topics and goals of the project.
- Experience with patients much appreciated.
- Sufficiently proficient in French to allow interaction with patients who will be subjects of experiments and with medical staff.
- Rigour, politeness, punctuality and caring attitude to interact with patients.
- Team spirit.

- Basic knowledge of Virtual Reality.
- Good proficiency in English (reading and writing).
- Ability and ease to write with clarity scientific papers in english.

- Good knowledge of softwares Python and Rstudio : if not, ability to learn them quickly.
- Basic knowledge in softwares Blender or Geogebra appreciated.
- Good operational knowledge of statistics.
- Knowledge of bayesian statistics and mixed-effects models appreciated.
- Basic knowledge in the fields of user experience and digital interactive systems appreciated.
- Basic knowledge in the field of gamification appreciated.

Work Context

The recruited candidate will work with an employment contract from the CNRS, an internationnally renown French multidisciplinary research organisation, and will be based in the « Laboratory of Cognitive Research - LPC » (UMR 7290 CNRS/AMU - https://lpc.univ-amu.fr/fr). This research « unit » is located in the center of Marseilles on the «Saint-Charles » University site and benefits from its integration within a vast network of Neuroscience laboratories. A large part of the recruited candidate's work will be in a medical center of Marseilles which specialises in retinopathies, the Monticelli-Paradis Ophthalmology Center (https://www.monticelli-paradis-retine.com/), where experiments with low vision patients will be performed all along the project.
DEVISE is integrated within the project of the « Perception and Attention » group, a pluridisciplinary team of 6 CNRS researchers or university research-teachers whose research focuses on normal and pathological vision (perceptual, attentional and oculo-motor processes). This project benefits from the financial and logistical resources of the LPC unit, of the « Perception and Attention » team and of the ANR DEVISE project.
The DEVISE consortium is pluridisciplinary and consists of three partners combining expertise in visual neuroscience (CNRS/University Aix Marseille - AMU, Lab. Of Cognitive Psychology – Coordinator partner), computer vision (Inria Sophia Antipolis, Biovision Team), and Virtual Reality ergonomics (AMU, the Mediterranean Virtual Reality Center (CRVM).

Constraints and risks

Major constraints arise from the necessity of working in a medical environment with low vision patients.
