Microsoft has recently released a mixed reality headset called Holo-Lens. This semi-transparent visor headset allows the user who wears it to viewthe projection of 3D virtual objects placed in its real environment. The usercan also grasp these 3D objects, which can also interact witheach other. Theframework of this new technology taking into account this physical approach(interactions, collisions) is calledmixed reality. We had the opportunity todigitally transform a conventional nutrition workshop forpatients waiting forbariatric surgery by designing a mixed reality software using the HoloLensheadset. This software is called HOLO_NUTRI.In this paper, we present this software and its assessment (acceptance ofthis technology) by a cohort of thirty patients.
