Sleep and wakefulness are no longer to be considered as discrete states. During wakefulness brain regions can enter a sleep-like state (off-periods) in response to a prolonged period of activity (local use-dependent sleep). Similarly, during nonREM sleep the slow-wave activity, the hallmark of sleep plasticity, increases locally in brain regions previously involved in a learning task. Recent st...

This contribution details how conceptual characterizations of route knowledge can provide the basis for graphical route information in a cognitively adequate way. The approach is based on the theory of wayfinding choremes that originated from the leitmotif to reflect mental conceptualization processes—as a canonical representation—in different modes of externalization, primarily graphical and v...

With the recent explosion of popularity of commercial social-networking sites like Facebook and MySpace, the size of social networks that can be studied scientifically has passed from the scale traditionally studied by sociologists and anthropologists to the scale of networks more typically studied by computer scientists. In this chapter, I will highlight a recent line of computational research...

The aim of this algorithm is to bridge the gap between high quality navigation services and low quality of location ...

SYNONYMS Wayfinding behavior; DEFINITION Wayfinding behavior is the purposeful, directed, and motivated movement from an origin to a specific distant destination that cannot be directly perceived by the traveler. It involves interaction between the wayfinder and the environment. Affordances are a concept from ecological psychology based on the paradigm of direct perception. They are specific co...

This article reports on an empirical evaluation of the experience, performance, and perception a deafblind adult participant in experimental case study pedestrian travel urban environment. The assessed degree seamlessness wayfinding experience pertaining to routes that traverse both indoor outdoor spaces under different modalities technology-aided travel. Specifically, traveler completed three ...

One category of Web application is an informational sites, which can be in the form of online newspaper, service manual, online electronic books, online help, online tutorial, and the like. One big target for designing a Web application in this category is to enable the user to search for information as quickly as possible. When user is doing his Web activity, he may develop some sort of mental...

Spatial representations are a result of multisensory information integration. More recent findings suggest that the multisensory information processing of a scene can be facilitated when paired with a semantically congruent auditory signal. This congruency effect was taken as evidence that audio-visual integration occurs for complex scenes. As navigation in our environment consists of a seamles...

A major challenge faced by the blind and visually impaired population is that of wayfinding—the ability of a person to find his or her way to a given destination. We propose a new wayfinding aid based on a camera cell phone, which is held by the user to find and read aloud specially designed machine-readable signs, which we call color targets, in indoor environments (labeling locations such as ...

BACKGROUND Multiple renovations and changing flow in a tertiary children's hospital in Cape Town resulted in numerous signs being posted in the corridors and units, making wayfinding extremely complex. A request from nursing management prompted the formation of a learning collaborative of nurses from all departments to improve wayfinding signage. OBJECTIVES The project aimed to contribute to ...
