Vision disorders reach 1.7 million people in France. According to the WHO, a doubling of the number of visually impaired people (DV) is expected by 2050 due to aging, with significant consequences on autonomy and quality of life. How to allow visually impaired people (from children to the elderly) to develop autonomy in their space activities?

The ACCESSPACE project (Learning space by cooperating from child to adult all coming and visually impaired: what verbal and technological aids?) Aims to highlight the developmental stages concerning the spatial skills studied via cooperative situations in the unborn child and the visually impaired child. The project will emphasize the multimodality (language and gestures) of space communication to make it accessible to a partner during daily space activities. The study of this will allow us to better understand the development of verbal and cognitive spatial strategies in people with visual impairments and typical at different periods of life (childhood, adolescence, adult, elderly).


The project will consist of the design and evaluation of an interactive device allowing to work without vision on space spots. This device will make it possible to study how to develop landmarks and ego- and allocent spatial strategies to guide a collaborator.
