“…Ils ont constaté que leur approche des lignes de soutien est la meilleure pour éliminer l'ambiguïté de la perception de la scène. Les mêmes types de projections ont été nommés lignes de chute ("dropping lines") par Ware et al [36] ou ancres d'ombres ("shadows anchors") par Ventura et al [34], mais toujours pour des objets au-dessus du sol.…”

Augmented Reality is increasingly used for visualizing underground networks. However, standard visual cues for depth perception have never been thoroughly evaluated using user experiments in a context involving physical occlusion (e.g. ground) of virtual objects (e.g. elements of buried a network). We hence evaluate the benefits and drawbacks of two techniques based on the combinations of two well-known depth cues: grid and shadows anchors. More specifically, we explore how each combination can contribute to positioning, and depth perception. We show that with shadows anchors only or combined with the grid, users generate 2.7 times fewer errors and have a 2.5 times lower perceived workload (NASA-TLX score) than with the grid only or no visual cue. Our investigation study shows that they are two effective techniques for visualizing underground objects. We also recommend the use of one technique or another depending on the situation in which they will be used.

“…Nous devons nous assurer que les objets sont vus là où nous voulons qu'ils soient vus par l'utilisateur. Récemment, en 2020, Ventura et al se focalisent dans leur cours [34] sur le problème de perception de la profondeur en réalité augmentée. Ils soulignent qu'il s'agit toujours d'un problème ouvert.…”
