“…The question of how to design with spatial layouts is complicated by navigational challenges in VEs, which can result in problems with spatial awareness or information gathering in 3D spaces [14]. Automating movement through the VE could relieve some of the problems of interactive navigation, but this effect can depend on the display and interaction methods [15]. Automatic navigation also risks losing the potential benefits of interactive methods.…”

Studying what design features are necessary and effective for educational virtual environments (VEs), we focused on two design issues: level of environmental detail and method of navigation. In a controlled experiment, participants studied animal facts distributed among different locations in an immersive VE. Participants viewed the information as either an automated tour through the environment or with full navigational control. The experiment also compared two levels of environmental detail: a sparse environment with only the animal fact cards and a detailed version that also included landmark items and ground textures. The experiment tested memory and understanding of the animal information. Though neither environmental detail nor navigation type significantly affected learning outcomes, the results suggest that manual navigation may have negatively affected the learning activity. Also, learning scores were correlated with both spatial ability and video game usage, suggesting that educational VEs may not be an appropriate presentation method for some learners. To address this issue, our research investigates how specific design features influence learner strategies and the effectiveness of learning when information is presented at different locations in a VE. Previous research has provided evidence that learners do reference locations when trying to remember information [7], and that presenting items in different locations can improve recall [8,9]. However, little is known about what factors influence these effects, and the flexibility of VEs leads to a large number of design factors for consideration. These factors include not only the design of the virtual content, but also the methods for accessing that content. KEYWORDSIn a controlled experiment, we studied how participants learned facts distributed among various locations within a VE. We evaluated differences in learning performance and learner strategies due to the level of navigational control and the level of environmental detail. Considering the design of the virtual content, we aim to better understand how a VE's environmental details and landmarks influence learning. Environmental details could also affect users' abilities to keep track of where certain information was located and which locations have been previously visited. Thus, this issue is closely related to the choice of an appropriate method for navigation within a VE. Our study compares interactive and automated navigation methods. Compared to automated presentations, fully manual navigation provides the freedom for learners to control the order and duration in which information is viewed, but at the cost of additional interaction and decisionmaking. RELATED WORKResearchers have suggested that VEs could provide advantages for conceptual learning by allowing opportunities for learners to view information within the context of meaningful locations [e.g., 4, 5, 10]. However, it is unknown whether a location is meaningful because of the information associated with that place or if the ...

“…The study measured relative effectiveness of the interaction techniques by both examining travel component (time taken to finish tasks/balloon shooting accuracy) and examining cognitive component (distance between the placed car marker and the car's actual position -measure also used in [3]). Using the questionnaire (based on continuous Likert scales) we measured participants' subjective impressions on the interaction techniques.…”

To characterize currently most common interaction techniques for street-level navigation in 3D digital cities for mobile touch devices in terms of their efficiency and usability, we conducted a user study, where we compared target selection (Go-To), rate control (Joystick), position control, and stroke-based control navigation metaphors. The results suggest users performed best with the Go-To interaction technique. The subjective comments showed a preference of novices towards Go-To and expert users towards Joystick technique.

“…Moreover Rekimoto [24] has shown that such a head-coupled perspective technique can improve the human's ability to understand complex 3D structures. It has been shown [12] that allowing the users to retain a control over the navigation helps them to familiarize with the 3D world.…”

RESUMENous présentons une technique d'interaction pour dispositifs mobiles (smartphone et tablette) basée sur le suivi du visage de l'utilisateur. Cette technique définit de nouvelles possibilités pour l'interaction en entrée et en sortie sur dispositifs mobiles. En sortie, le suivi de la tête peut permettre de contrôler le point de vue sur une scène 3D affichée à l'écran (Head-Coupled Perspective, HCP). Cette technique améliore l'interaction en sortie en offrant la perception de la profondeur et en permettant la visualisation d'un espace de travail plus grand (fenêtre virtuelle). En entrée, le suivi des mouvements de la tête définit une nouvelle modalité d'interaction qui ne requiert pas d'autres capteurs que la caméra du téléphone ou de la tablette. Dans cet article, nous explicitons les possibilités interactionnelles offertes par le suivi de la tête de l'utilisateur sur téléphones ou tablettes, particulièrement adapté au caractère mobile des dispositifs visés. Nous focalisons ensuite sur l'interaction en sortie en présentant plusieurs applications du HCP et en décrivant les résultats d'une expérimentation qualitative sur téléphone et tablette. ABSTRACTWe study interaction modalities for mobile devices (smartphones and tablets) that rely on a camera-based head tracking. This technique defines new possibilities for input and output interaction. For output, by computing the position of the device according to the user's head, it is for example possible to realistically control the viewpoint on a 3D scene (Head-Coupled Perspective, HCP). This technique improves the output interaction bandwidth by enhancing the depth perception and by allowing the visualization of large workspaces (virtual window). For input, head movement can be used as a means of interacting with a mobile device. Moreover such an input modality does not require any additional sensor except the built-in front-facing camera. In this paper, we classify the interaction possibilities offered by head tracking on smartphones and tablets. We then focus on the output interaction by introducing several applications of HCP on both smartphones and tablets and by presenting the results of a qualitative user experiment.
