We investigated how visual and kinaesthetic/efferent information is integrated for speed perception in running. Twelve moderately trained to trained subjects ran on a treadmill at three different speeds (8, 10, 12 km/h) in front of a moving virtual scene. They were asked to match the visual speed of the scene to their running speed–i.e., treadmill’s speed. For each trial, participants...

(Internal working papers DIUF ; 15-03)

This paper compares an emergent interaction modality for the In-Vehicle Infotainment System (IVIS), i.e., gesturing on the steering wheel, with two more popular modalities in modern cars: touch and speech. We conducted a betweensubjects experiment with 20 participants for each modality to assess the interaction performance with the IVIS and the impact on the driving performance. Moreover, we...

Au sein de la médecine moderne, les changements technologiques ont tout particulièrement modifié la pratique de l’imagerie médicale. Les progrès concernent toutes les étapes du processus : l’acquisition des images, le post-processing, le stockage, la recherche d’images et enfin leur transmission. Ces améliorations ont engendré une augmentation de la qualité des soins, de la...
