HyperContext is a framework for adaptive and adaptable hypertext. In any hyperspace, each piece of information (e.g., contained in a document or node) is normally juxtaposed by other information via links. Two or more hypertext users may encounter the same document although they may have followed different paths to reach it. Those two users may well describe different aspects of the document as...

Dieser Artikel diskutiert neue Lehr-/Lernmethoden für interdisziplinäre Fachgebiete wie z. B. Operations Research/Management Science. Die notwendigen Fähigkeiten zur richtigen Anwendung quantitativer Methoden müssen, ähnlich dem Erlernen eines Handwerks, erst erworben werden. Wir argumentieren, daß der Lernprozeß durch die Behandlung von Fallstudien in Verbindung mit einer hypermedialen Lernumg...

If X is a space then L(X) denotes the subspace of C(X) consisting of all Peano (sub)continua. We prove that for n ≥ 3 the space L(R) is homeomorphic to B∞, where B denotes the pseudo-boundary of the Hilbert cube Q. Introduction. For a space X, C(X) denotes the hyperspace of all nonempty subcontinua of X. It is known that for a Peano continuum X without free arcs, C(X) ≈ Q, where Q denotes the H...

Navigation (colloquially known as “surfing”) is the activity of following links and browsing web pages. This is a time intensive activity engaging all web users seeking information. We often get “lost in hyperspace” when we lose the context in which we are browsing, giving rise to the infamous navigation problem. So, in this age of information overload we need navigational assistance to help us...

In the context of exploring educational hypermedia on the World Wide Web, this paper presents a history visualization that helps learners reorganize explored contents to find what Web sites they should visit next. Learning-by-exploration is discussed as it relates to educational hypermedia, including the "Get Lost in Hyperspace" problem, learning support approaches, and current work on hypermed...

Hypermedia and multimedia capability of web supports the new constructivist way of active learning. However, it may lead to cognitive overload and resulting in `disorientation` or `lost in hyperspace` problem. To reduce this cognitive overload the content should be tailored to individual differences of users. Psychological factor is one of many factors that influence characteristics of individu...

The point-to-set principle of J. Lutz and N. (2018) has recently enabled the theory computing to be used answer open questions about fractal geometry in Euclidean spaces $\mathbb{R}^n$. These are classical questions, meaning that their statements do not involve computation or related aspects logic. In this paper we extend reach from arbitrary separable metric $X$. We first two dimensions--com...

Let M be the collection of all intersections of balls, considered as a subset of the hyperspace H of all closed, convex and bounded sets of a Banach space, furnished with the Hausdorff metric. We prove that M is uniformly very porous if and only if the space fails the Mazur intersection property.
