Cette thèse s'inscrit dans le domaine de l'Interaction Homme-Machine (IHM) et est dédiée à l'interaction en Réalité Augmentée (RA) sur dispositifs mobiles.La RA permet l'ajout de contenu numérique, principalement graphique, à l'environnement physique de l'utilisateur. L'environnement mixte ainsi obtenu comprend des objets numériques ancrés dans le...
Navigating Augmented Reality (AR) environments with a handheld device often requires users to access digital contents (i.e. Points of Interests - POIs) associated with physical objects outside the field of view of the device's camera. Halo3D is a technique that displays the location of off-screen POIs as halos (arcs) along the edges of the screen....
When working with mobile Augmented Reality (AR), users often need to visualize off-screen points of interest (POIs). These POIs belong to the context since they are not directly observable in the 3D first-person view on screen. The aim is to present the 3D direction and distance of each POI in a 3D first-person view. The context in mobile AR can in...

... The approach to benefit selection by enlarging the targets is not completely new. The target expansion technique, which allowed targets to expand dynamically as the cursor approaches (McGuffin and Balakrishnan 2005), was proved to enhance performance using a mouse (Hwang et al. 2013) and a touch display (Yang et al. 2011;Perea et al. 2020). With a VR headset, Yang et al. (2019) applied a similar strategy to magnify keys in a virtual keyboard and found enhancement in the performance of VR text entry. ...

... Une seconde méthode pour visualiser l'environnement mixte passe par un dispositif mobile comme un téléphone portable ou une tablette [138,162] La RA peut aussi bénécier à de nombreux domaines d'applications professionnels. Ainsi, elle est en passe de devenir un outil précieux pour l'assemblage, la maintenance et la réparation d'équipements industriels [13,154]. ...
... Viewing AR content on the ceiling or floor (e.g., Fig. 1A) can be affected by perceptual factors, like the distance perception [11] as content could be out-of-view. Therefore, it is necessary to make users aware of such content by notifying or guiding them to it with the help of visual aids (e.g., [5,22,48]) or change the distance (d) to the content to support its visibility. Other perceptual factors, such as text perception [20], color perception [35], or visual attention [38], can be of importance as well. ...

... From these scenarios, we derive two challenges for handheld AR industrial maintenance guidance systems: (1) manage POI-dense environments and (2) keep intrusion minimal and constant along the screen's edges to avoid overloading the focus area, used to consult data of selected POIs. Perea et al. introduced Halo3D ([17], [18]), an AR technique to visualize off-screen POIs on handheld devices. Halo3D is adapted from Halo [1] a 2D visualization technique. ...
