“…A good understanding of human way finding strategies [1,2,3] and underlying perceptual and cognitive processes [1] is of particular importance to optimally support human spatial navigation in virtual environments. Virtual environments can be more complex than natural environments with respect to their scale [4,2], structural complexity and dimensionality [5].…”

It has been shown that multisensory presentation can improve perception, attention, and object memory compared with unisensory presentation. Consequently, we expect that multisensory presentation of landmarks can improve spatial memory and navigation. In this study we tested the effect of visual, auditory and combined landmark presentations in virtual mazes on spatial memory and spatial navigation. Nineteen participants explored four different virtual mazes consisting of nodes with landmarks and corridors connecting them. Each maze was explored for 90 seconds. After each exploration, participants performed the following tasks in fixed order: 1) draw a map of the maze, 2) recall adjacent landmarks for three given landmarks, 3) place all landmarks on the map of the maze, and 4) find their way through the maze to locate five given landmarks in fixed order. Our study shows significant effects of multisensory versus unisensory landmarks for the maze drawing task, the adjacency task, and the wayfinding task. Our results suggest that audiovisual landmark presentations improve spatial memory and spatial navigation performance in virtual environments.

“…In line with this last point, wayfinding research (Hölscher et al, 2009) has shown that people's strategy choice indoors varies with different navigation tasks. Tasks with either a floor change or a building part change result in no problems, with the participants first changing to the correct floor or building part.…”

“…This has its origin in the explicit distinctiveness in structure, constraints and usage between indoor and outdoor environments (Li, 2008;Walton & Worboys, 2009). Also, wayfinding tasks in multi-level buildings have proven to be more challenging than outdoors, for reasons of disorientation and less visual aid (Hölscher et al, 2009). As such, building occupants are faced with a deficient perspective on the building structure, influencing their movement behavior (Hölscher et al, 2009).…”

As such, building occupants are faced with a deficient perspective on the building structure, influencing their movement behavior (Hölscher et al, 2009). Algorithms developed to support a smooth navigation will have to consider these intricacies and create route instructions that are more aligned with the human cognitive mapping of indoor spaces.…”

ABSTRACT:Over the last couple of years, applications that support navigation and wayfinding in indoor environments have become one of the booming industries. However, the algorithmic support for indoor navigation has so far been left mostly untouched, as most applications mainly rely on adapting Dijkstra's shortest path algorithm to an indoor network. In outdoor space, several alternative algorithms have been proposed adding a more cognitive notion to the calculated paths and as such adhering to the natural wayfinding behavior (e.g. simplest paths, least risk paths). The need for indoor cognitive algorithms is highlighted by a more challenged navigation and orientation due to the specific indoor structure (e.g. fragmentation, less visibility, confined areas…). Therefore, the aim of this research is to extend those richer cognitive algorithms to three-dimensional indoor environments. More specifically for this paper, we will focus on the application of the least risk path algorithm of Grum (2005) to an indoor space. The algorithm as proposed by Grum (2005) is duplicated and tested in a complex multi-story building. Several analyses compare shortest and least risk paths in indoor and in outdoor space. The results of these analyses indicate that the current outdoor least risk path algorithm does not calculate less risky paths compared to its shortest paths. In some cases, worse routes have been suggested. Adjustments to the original algorithm are proposed to be more aligned to the specific structure of indoor environments. In a later stage, other cognitive algorithms will be implemented and tested in both an indoor and combined indoor-outdoor setting, in an effort to improve the overall user experience during navigation in indoor environments.
