Hypermedia is a term first used in a 1965 article by Ted Nelson. It is used as a logical extension of the term hypertext in which graphics, audio, video, plain text and hyperlinks intertwine to create a generally non-linear medium of information. This contrasts with the broader term multimedia , which may be used to describe non-interactive linear presentations as well as hypermedia. Hypermedia should not be confused with hyper graphics or which is not a related subject. It is also related to the field of Electronic literature. нуρєямє∂ια
Figure 1 shows a process of organizing well-structured hypermedia by applying CHI as a refinement tool. A person can author his/her own idea to put it into the hypermedia interactively. Then, he or she can augment another idea from the well-organized data. In some cases and at some levels, computers can automatically generate the structure and take advantage of its utility by applying media recognition and media understanding technologies. In order to coordinate these processes appropriately, CHI plays an important role in refining the hypermedia information.
The World Wide Web hypertext/media system allows the user to freely navigate between nodes by following links in an extensive, decentralized network of information and knowledge. The open, free-browsing nature of the web affords exploratory and inquiry-based learning with a high degree of student control. At the same time however, given the extensive growth of the World Wide Web, the potential is great for user disorientation in such a large knowledge base. A further problem with hypermedia navigation is that it is not specifically designed to differentiate between and to accommodate users with different interests, goals and needs. Thus, traditional hypermedia systems present a disadvantage for educational use of the World Wide Web since without direct teacher or system support, students' learning experiences may not be very efficient or effective. While a discovery or inquiry-based type of online learning may be envisioned as an effective model, it nonetheless needs to be coupled with some type of system control or support.
нуρєямє∂ια ѕуѕтємѕ Systems divide into two major categories: browsers for the WWW, and integrated hypermedia systems. The two categories are not completely independent, since integrated systems generally can produce HTML readable by WWW browsers, and can display HTML as a degenerate case of the system's complete functionality.
