              <p>Les timelines impliquant des objets 3D peuvent être rendues en RV pour faciliter leur visualisation et diverses formes d’analyse de données, telles que la localisation d’un objet donné ou la détection de motifs. Alors que différentes formes de timelines ont étéproposées en 3D, telles que la forme convexe ou linéaire, la forme concave a été envisagée mais n’a pas fait l’objet d’une comparaison expérimentale. Dans cet article, nous effectuons la comparaison expérimentale d’une forme de timeline concave avec d’autres formesexistantes. Nous démontrons que les utilisateurs préfèrent la forme concave, qui permet de réaliser plus rapidement les tâches de localisation d’un objet et de détection de motifs.</p>

              <p>Timelines involving 3D objects can be rendered in RV to facilitate their visualization and various forms of data analysis, such as object location or pattern detection. While different timeline shapes have been proposed in 3D, such as convex or linear, the concave shape hasbeen envisioned but not experimentally compared to. In this paper, we perform the experimental comparison of a concave timeline shape against other existing shapes. We demonstrate that users prefer the concave shape, which allows for faster object selectionand pattern detection.</p>
