Web page vs. Web site
A site consists of individual pages www.oamk.fi/ is a site, which has many
pages (e.g. www.oamk.fi/english/ouas/) The pages of the site share
A consistent look & feel Links between them
The pages don’t have to be located in the same server (Usually they are)
Information Search (1)
Information search from the Web has become one of the basic IT-skills
With faster connections, the users are requiring faster and more accurate results
Many Web sites also include internal search functionalities
Information Search (2) Recognition of the correct
information is often problematic The Web users want to
find information quickly see the information in an organized way get help for finding more information
about the search topic Often the users don’t know exactly
what they are looking for (= surfing)
Information Search (3)
When designing a Web site, it is important to offer an overview about the contents: Header/footer texts Images
”Aesthetic minimalism” is often mentioned as a general principle of the Web design
Search engines
Often the Web users use search pages to find information AltaVista Google Yahoo
The search engines are based on the use of the bots &/ indexing
E-commerce Sites The popularity of buying over Web
has been increasing quickly The factors affecting to the
popularity are easiness of buying large amount of products available fear of getting hoaxed (credit cards,
private information) difficulties with returned products etc.
Web publishing (1) Even if Web publishing is a separate
area, it shares many rules & principles with the print publishing: use of colors fonts layouts
On the other hand, there are special requirements and restrictions (e.g. designing for the browser versions & user settings)
Web publishing (2) Nowadays implementing a Web site
is technically rather easy Implementing a site with a good
usability and interesting contents is still a challenging task
The Web sites also require updates: Contents Web addresses / links Etc.
The Representation of a Web Page (1)
Methods of viewing a page include: Computer display screen PDA device / mobile phone browser Printed on a paper
Most of the pages have been optimized for computer displays
The Representation of a Web Page (2)
The browsers of different vendors (IE, Opera, Mozilla-based) do not represent the pages in an uniform way
It is possible to make the server recognize the client requesting the page and thus optimize the contents for different kinds of environments
Accessibility (1) The users of the Web differ in
Cognitive skills Computer use experience Sensory skills Motoric skills
Accessibility has been set as one of the Web’s general requirements (Compare to the public buildings)
Accessibility (2)
Many pages include restricting content like: Plugin based functionalities (Flash, Java..) Small, non-adjustable font sizes Text contents that are difficult to
understand ’Universal accessibility’ is in practice
impossible to achieve, but it is still a worthy goal
Markup Web pages are based on the use of
a markup language (HTML) The browsers parse the markup and
present the page in a GUI view HTML is implemented by
the Web Editors (generated automatically)
Web designers (handwritten)
