DEFINITIONS(1) • HYPERMEDIA is an extension to hypertext that supports linking graphics, sound, and video elements in addition to text elements. • HYPERTEXT is a special type of database system, in which objects (text, pictures, music, programs, and so on) can be creatively linked to each other.
ASPEN MOVIE MAP • This is an early example of a hypermedia system. It allows users to take a virtual tour through Aspen, Colorado.
WWW or World Wide Web WWW is a system of interlinked, hypertext documents that runs over the Internet. A user can view Web pages that contain text, images, and other multimedia and navigates between them using hyperlinks. It was created around 1990 by a Britain named Tim Berners-Lee and a Belgian named Robert Cailliau working in Geneva, Switzerland.
ULTRAWAVE OR HYPERWAVE ü Ultra waves are a concept used in science fiction to represent transmissions or signals that may move faster than light through either normal space, alternate space, such as hyperspace or subspace. Waves that exist is hyperspace are known as Hyper waves.
TED NELSON (1) Theodor Holm Nelson was an American sociologist, philosopher, and pioneer of information technology. He is the “father” of hypermedia and has worked to make computers easily accessible to ordinary people. He is also credited with the first use of the words tranclusion, virtuality, intertwingularity, and teledildonics.
TED NELSON(2) • Nelson founded Project Xanadu in 1960 with the goal of creating a computer network with a simple user interface. • He is currently working on a new information structure, Zig. Zag, which is described on the Xanadu project website.
PROJECT ZANADU • Founded by Ted Nelson, this was the first hypertext project. • It began as a word processor capable of storing multiple versions, and displaying the differences between these versions. • Nelson developed the concept of “zippered lists” that allowed compound documents to be formed from pieces of other documents, a concept known as transclusion.
PROJECT ZANADU(2) In 1967, while working for Harcourt-Brace, Nelson named his project Xanadu, in honor of the poem Kubla Khan by Samuel Taylor Coleridge. In 1972, Cal Daniels completed the first demonstration version of the Xanadu software on a computer. In 1998, Nelson released the source code to Xanadu as Project Unadax , in hopes that the technique and algorithms used could turn over some of the software patents.
ADVANTAGES Ø One of the major advantages of hypermedia is the ability to quickly follow associations and look up related material. Ø Another advantage of hypermedia for learning applications is that they can be fun to use.
DISADVANTAGES q. The ease of browsing may increase the risk of the learner skipping through the materials and getting fragmented information. q. An addition problem with hypermedia is that its use involves a certain cognitive overhead.
