1.8 Hypertext and means hypermedia
The hypertext is a method of non-linear submission of a text material in case of which in the text there are somehow selected words having a binding to certain text fragments. Thus, the user not simply goes through in the order of the text page, it can deviate the linear description according to any link, i.e. itself controls process of output of information. In hypermedia to system as fragments images can be used, and information may contain the text, a graphics, video fragments, a sound.
Use of hypertext technology meets such requirements imposed to textbooks, as structuredness, convenience in the address. If necessary such textbook can be "laid out" on any server and it can be adjusted easily. But, as a rule, the unsuccessful design, configuration, structure, etc. are peculiar to them.
Now there is a set of different hypertext formats (HTML, DHTML, PHP, etc.).
1.9 Selection terms of means
In case of a choice of means the existence assessment is necessary:
• Hardware of a certain configuration;
• the certified program systems;
• experts of required level.
Besides, it is necessary to consider assignment of developed EU, need of modification of addition by new data, restriction on memory size, etc.
Thanks to roughly developing technology of means of a multimedia and hypermedia become rather cheap to set them on the majority personal computers. Besides, the power and high-speed performance of hardware allow to use above-mentioned means.
1.10 Structural organization of the electronic textbook
In the market of computer products the number of learning programs, electronic textbooks, etc. increases every year. At the same time disputes on what shall be "the electronic textbook", what functions "are imputed to it a duty" don't cease. Traditional creation of EU: presentation of a training material, practical part, testing.
Now the following requirements are imposed to textbooks:
1 . Information on the selected course shall be well structured and represent itself the finished fragments of course with limited number of new concepts.
2 . Each fragment, along with the text, shall provide information in audio-or video ("live lectures"). The line of the scrolling, allowing to repeat lecture from any place will be a mandatory member of the interface for live lectures.
3 . Text information can duplicate some part of live lectures.
4 . On the illustrations representing difficult models or devices, there shall be the instantaneous help appearing or disappearing synchronously with movement of the cursor on separate elements of an illustration (a card, the plan, the diagram, the drawing of assembly of a product, the control panel object, etc.).
5 . The text part shall be accompanied by the numerous cross-references, allowing to reduce search time of necessary information, and also powerful retrieval center. Connection of the specialized explanatory dictionary on this data domain can be a perspective element.
6 . Video information or animations shall accompany with sections which are difficult for understanding in normal presentation. In this case time expenses for users are five-ten times less in comparison with the traditional textbook. Generally the person can't describe some phenomena, never their seeing (falls, fire, etc.). Video clips allow to change time scale and to show the phenomena in the accelerated, slow-motion or selective shot.
7 . Existence of audio information which in many cases is the main and sometimes irreplaceable informative part of the textbook.
