Acquisition visuelle en réalité mixte, depuis et vers une table interactive : Analyse de la transition entre un écran virtuel et un écran physique: Visual acquisition in mixed reality, from and to an interactive table: Analysis of the transition between a virtual screen and a physical screen.

As part of a project to explore the opportunities and limitations created by the addition of a new interaction space around an interactive table, through an augmented reality headset, this paper aims to better understand the nature and characteristics of the new combined display space, as well as the role of the physical screen in this otherwise virtual environment. We also question the impact of directly superimposing augmented content on the physical screen, or on the contrary of strictly separating the two display environments. To this end, 12 participants performed visual acquisition tasks between these two spaces (tabletop and pure virtual area), with either a physical or virtual display at the tabletop. The results show better performance with strict use of the physical display for the tabletop area and an ability for the user to focus their gaze more towards the surrounding virtual areas.
