A core set of navigational aspects may be found by extracting the key features of hypermedia applications. Incorporated to an information system (IS), they may increase its utility and usability (1). This type of extension of an IS is called ‘The Hypertext Functionality Approach’ (2), and it may be done in different ways. In this paper we present a novel approach to add navigational features in...

Animals navigate over a range of distances, but it has been the global navigation of species migrating among spatially restricted, seasonal homes separated by thousands of kilometers that continues to defy a thorough mechanistic explanation. We survey the navigational behavior of migratory salmon, whales, sea turtles, and birds, as well as dispersing monarch butterflies, to promote the idea tha...

Most of us know people who ‘‘cannot read a map’’ and others who seem to navigate intuitively. Such discrepancy in ability is puzzling, given that most people navigate to and between locations many times every day. In many cases the locations are those that are destinations we visit regularly (school, work, home, store), but people are also frequently faced with the task of navigating to a new l...

Visual mental imagery is a process that draws on different cognitive abilities and is affected by the contents of mental images. Several studies have demonstrated that different brain areas subtend the mental imagery of navigational and non-navigational contents. Here, we set out to determine whether there are distinct representations for navigational and geographical images. Specifically, we u...

Insects face the challenge of navigating to specific goals in both bright sun-lit and dim-lit environments. Both diurnal and nocturnal insects use quite similar navigation strategies. This is despite the signal-to-noise ratio of the navigational cues being poor at low light conditions. To better understand the evolution of nocturnal life, we investigated the navigational efficiency of a nocturn...

Virtual environments provide a computer-synthesized world in which users can interact with objects, perform various activities, and navigate the environment as if they were in the real world (Sherman & Craig, 2002). Research in a variety of fields (i.e., software engineering, artificial intelligence, computer graphics, human computer interactions, electrical engineering, psychology, perceptual ...

Anatomical evidence and conditioning experiments have suggested that magnetoreceptors innervated by the ophthalmic branch of the trigeminal nerve are located in the upper beak of homing pigeons. Following these findings it has been proposed that the trigeminally-mediated magnetorececeptors are able to detect magnetic field intensity, which might be useful for a position finding mechanism for pi...

This chapter proposes design patterns for object-oriented applications enhanced with hypermedia functionality. We briefly discuss our problem: building a software architecture for seamlessly extending object-oriented applications with hypermedia interface and navigational styles. Two new design patterns named ‘Navigation Strategy’ and ‘Navigation Observer’ are presented, showing how they are us...

The main issue addressed in this paper is how to improve the coordination between navigational learning process and its meta-cognitive process in hyperspace provided by existing Web resources, which includes coordinating two different meta-cognitive processes: navigation planning and reflection. This paper demonstrates the cognitive tool, which enables learners to reify and coordinate their nav...

Background. Human spatial navigation can be conceptualized as egocentric or exocentric, depending on the navigator’s perspective. Navigational impairment is known to occur in individuals with cognitive impairment, but less is known about navigational abilities in nondemented older adults. Our objective was to develop tests of navigation and study their cognitive correlates in nondemented older ...
