Simulating Navigation With Virtual 3d Geovisualizations – A Focus on Memory Related Factors

Abstract

ABSTRACT:The use of virtual environments (VE) for navigation-related studies, such as spatial cognition and path retrieval has been widely adopted in cognitive psychology and related fields. What motivates the use of VEs for such studies is that, as opposed to real-world, we can control for the confounding variables in simulated VEs. When simulating a geographic environment as a virtual world with the intention to train navigational memory in humans, an effective and efficient visual design is important to facilitate the amount of recall. However, it is not yet clear what amount of information should be included in such visual designs intended to facilitate remembering: there can be too little or too much of it. Besides the amount of information or level of detail, the types of visual features ('elements' in a visual scene) that should be included in the representations to create memorable scenes and paths must be defined. We analyzed the literature in cognitive psychology, geovisualization and information visualization, and identified the key factors for studying and evaluating geovisualization designs for their function to support and strengthen human navigational memory. The key factors we identified are: i) the individual abilities and age of the users, ii) the level of realism (LOR) included in the representations and iii) the context in which the navigation is performed, thus specific tasks within a case scenario. Here we present a concise literature review and our conceptual development for follow-up experiments.

Evaluation of User Performance in Interactive and Static 3D Maps

“…Static 3D maps can be also tangible (for example printed by 3D printer), but in this paper, we deal only with 3D virtual maps that are displayed on the computer screen This paper consists of a theoretical section, which is a literature review, and an empirical section, which is an experimental study. The literature review is divided into three parts, according to three fundamental factors important in cartography user studies: Stimuli, task, and user [11,12]. The main objectives of the empirical section relate to these three dimensions.…”

The effect of microlevel and macrolevel signaling on learning with 360° videos

“…Following previous attempts (Jarodzka et al, 2013; Yang, 2020), one type of signaling (i.e., macrolevel signaling) reduces the negative effect of the transient information effect by directing learners' attention to the relevant field of view at the time the relevant information is presented. This might be done by, for example, spotlights that darken (Jarodzka et al, 2013) or abstract (Lokka & Çöltekin, 2016) nonrelevant areas, gestures, and verbal statements that direct attention (Sheikh et al, 2016), textual annotations (Albus et al, 2021), or inserting directional cues such as progressive arrows (Yang, 2020). These cues help adjust the image detail to the learning‐relevant area of a 360° video and orientate it within the room.…”

A Review of Photogrammetry and Photorealistic 3D Models in Education From a Psychological Perspective

“…A substantial lack of research suggests a major challenge for the use of photogrammetry in education. In contrast to other fields, such as cartography (Wilkening and Fabrikant, 2011), landscape visualization (Lange, 2001), virtual avatars (Latoschik et al, 2017), cognition (Lokka and Çöltekin, 2016), or the concept of presence (Cummings and Bailenson, 2016;van Gisbergen et al, 2019), research on realistic virtual objects in the field of instructional psychology is comparably scarce. Another challenge arises from the questionable transferability of the insights gained from related fields.…”
