WebMar 22, 2024 · Raycasting is a set of interaction techniques used in immersive environments for selection of targets at the distance. Raycasting resembles real-life pointing with a laser pointer: the user points a ray of light at the target and confirms its selection with a motion gesture, a voice command, or a button click. WebIn this paper we investigate the effectiveness of geolocative raycasting, a technique which enables the real-time estimation of the user’s field of view in outdoors mobile applications, as a complementary method for enhancing the robustness of marker-based AR applications, thus mitigating the effect of lighting sensitivity.
