What is accessibility
It is a term that is more associated with architectural thought, rather than Web Site Design. There is a legislation, which determines the minimum standards for new buildings.
According to the World Wide Web Accessibility Initiative, providers have the following benefits:
1. Increase Market Share and Audience Reach
2. Improve Efficiency
3. Demonstrate Social Responsibility
4. Reduce Legal Liability
Accessibility is critical for a web site's success
For example, in the UK alone, there are 8.5 million people who are classified as having some sort of disability. That's a big percentage to exclude from the web; from a moral viewpoint, it is surely wrong, but from a commercial viewpoint, it is disastrous.
When designing web pages, try putting them through a text reader, like the ones used by those with visual impairment.
You will soon realize how difficult it can be for a user who cannot see that a new window has opened - hence the need to overtly tell users that a new window has indeed opened.

Week 11 What is Web 3.0?
Web 3.0 is one of the terms used to describe the evolutionary stage of the Web that follows Web 2.0. Given that technical and social possibilities identified in this latter term are yet to be fully realised the nature of defining Web 3.0 is highly speculative. In general it refers to aspects of the internet which, though potentially possible, are not technically or practically feasible at this time.
Web 3.0, a phrase coined by John Markoff of the New York Times in 2006, refers to a supposed third generation of Internet-based services that collectively comprise what might be called 'the intelligent Web'—such as those using semantic web, microformats, natural language search, data mining, machine learning, recommendation agents, and artificial intelligence technologies—which emphasize machine-facilitated understanding of information in order to provide a more productive and intuitive user experience.
Web 3.0 has been described as the "executable web". In the analogy to file system permissions, Web 1.0 was "read-only", Web 2.0 is "read-write", and Web 3.0 will be "read-write-execute".

Week 10 Other forms of web marketing
Some of the popular forms include: Contextual advertising:
Contextual advertising is one of the most popular forms of search advertising. Contextual advertising entails the placement of ads on web pages, whose content match with the content displayed on the website.
PPC [Pay-Per-Click]:
The URL gets listed only when the keywords typed in by the user matches with those selected by the advertiser.
Affiliate Marketing:
Basically, the affiliate has to display a banner, products or URLs of the advertiser on its website. The commission can be paid on cost-per-click, cost-per-sale, cost-per-lead basis.
Rich Media Advertising:
Rich Media Advertising refers to the use of streaming audio and video as well as applets for the promotion of the website. The audio or video placed on a web page offers interactivity to the viewers.
RSS:
RSS stands for Really Simple Syndication. If a web surfer chooses a RSS option for a particular website, he will be able to keep abreast of the latest content that is being uploaded on a website. RSS is also being popularly used by the advertisers to inform the customers about the latest discounts, bargains and offers.
Blogging:
allows them to slip the information about the likely new launches in a rather stealth manner. Businesses are also exploring the option of sponsoring a blog, which shares its synergies with the products and services of the company. Many business entities are also going in for getting their ads displayed on blogs.
Viral Marketing:
A friend reads an interesting offer, article or informative write-up and informs his friend. This friend then forwards, the same to his friend and the chain continues; thus, acting like a virus. Experts have noticed that the spread of information is faster if there are some freebies, discounts or special offers up for grabs.
Search Engine Optimization:
Search Engine Optimization is tweaking the site to enhance the rankings obtained by it on the search engines. It involves processes such as optimizing the content with a proper set of keywords or key phrases as well as making the site navigation structure much more friendly to users. It also includes taking small but vital steps such as getting linked to sites having higher page ranks, submission of sites to directories etc.
Podcasting:
Podcasts can be used for the purpose of information dissemination. This form of Internet advertising entails the insertion of audio clips in the audio files that are available for listening. The biggest advantage of podcasting is that it allows one to target niche audience.
Behavioral advertising:
If a web surfer frequently visits sports section or sports site, then under behavioral advertising, he will mostly witness ads that are related to sports. So, even if he is surfing the net to buy that occasional pizza, he will be able to view sports ads. Thus, under behavioral advertising, the content of the site becomes irrelevant and the ads shown to a visitor are purely related to his past surfing habits.
Mobile marketing:
Under mobile marketing, the target audience is usually sent a SMS or a MMS to inform about the latest product or services that might be of interest to them.

Week 7 What kind of assistive devices are there?
Assistive technology products are designed to provide additional accessibility to individuals who have physical or cognitive difficulties, impairments, and disabilities
Braille embossers
Braille translation programs convert text scanned-in or generated via standard word processing programs into Braille, which can be printed on the embosser.
Keyboard filters
Keyboard filters enable users to quickly access the letters they need and to avoid inadvertently selecting keys they don't want.
Light signaler alerts
This is useful when a computer user can not hear computer sounds or is not directly in front of the computer screen. As an example, a light can flash alerting the user when a new e-mail message has arrived or a computer command has completed.
On-screen keyboards
On-screen keyboards often have a scanning option that highlights individual keys that can be selected by the user. On-screen keyboards are helpful for individuals who are not able to use a standard keyboard due to dexterity or mobility difficulties.
Reading tools and learning disabilities programs
make text-based materials more accessible for people who have difficulty with reading. Options can include scanning, reformatting, navigating, or speaking text out loud.
Refreshable Braille displays
A Braille "cell" is composed of a series of dots. The pattern of the dots and various combinations of the cells are used in place of letters. The user reads the Braille letters with his or her fingers, and then, after a line is read, can refresh the display to read the next line.
Screen enlargers, or screen magnifiers,
increase legibility and make it easier to see items on the computer. Some screen enlargers allow a person to zoom in and out on a particular area of the screen.
Screen readers
are used to verbalize, or "speak," everything on the screen including text, graphics, control buttons, and menus into a computerized voice that is spoken aloud. In essence, a screen reader transforms a graphic user interface (GUI) into an audio interface. Screen readers are essential for computer users who are blind.
Speech recognition or voice recognition programs,
enter data using their voices rather than a mouse or keyboard. Voice recognition systems use a microphone attached to the computer, which can be used to create text documents such as letters or e-mail messages, browse the Internet, and navigate among applications and menus by voice.
Text-to-Speech (TTS) or speech synthesizers receive information
Using speech synthesizers allows computer users who are blind or who have learning difficulties to hear what they are typing and also provide a spoken voice for individuals who can not communicate orally, but can communicate their thoughts through typing.
Talking and large-print word processors
use speech synthesizers to provide auditory feedback of what is typed. Large-print word processors allow the user to view everything in large text without added screen enlargement.
TTY/TDD conversion modems
allow an individual to type a message on a computer and send it to a TTY/TDD telephone or other Baudot equipped device.

Week 5 What are the most popular fonts on the Web?
Verdana is one of the most popular of the fonts designed for on-screen viewing.
simple, straightforward design, and the characters or glyphs are not easily confused.
The spacing between letters in Tahoma is tighter than either Arial or Verdana, giving a somewhat "scrunched together" appearance, especially when compared to Verdana, and especially when used for long passages of text. Tahoma is still an acceptable font, but is probably somewhat less readable overall than Verdana or Arial/Helvetica for long passages of text.
Trebuchet may decrease overall readability for long passages of text. Some of the glyphs are also presented in a non-standard, more decorative format, such as the ampersand (&), which may also decrease readability.
In terms of accessibility, it is better than some fonts, but not as good as others.
Georgia is somewhat easier on the eyes than Times New Roman, although high resolution screens with font smoothing technology also display Times New Roman quite well. One advantage of using Georgia is that it is not the default text of the browser. It is easier for users to see that the designer has applied some style to the font when fonts other than the default font are specified.
