Challenges
- Usability
Many people think there’s nothing to it.
- Standards
People have heard of it, but are not familiar with what it’s all about.
- Accessibility
Most people don’t know what it is (including developers), and many who do don’t fully understand it.
Usability
Usability is the measure of the quality of a user's experience when interacting with a product or system.
“Usable” web sites are:
- Quick and easy to learn
- Efficient to use
- Easy to remember
- Enjoyable to use
- Aesthetically pleasing
- Allow rapid recovery from errors
Usability, Cont.
According to Steven Krug, every page should have:
- Site ID (logo)
- Page name/title
- Sections and subsections
- Local navigation
- “You are here” indicator (in menu or breadcrumbs)
- Search function
Krug's book is "Don't Make Me Think". You can also learn more from usability expert Jakob Nielsen.
Dennis says, “Don’t forget your address and/or contact information on every page!”
Standards
- Adhere to the world's standards and guidelines set by the World Wide Web Consortium (W3C).
- Separate content from design.
- Most web sites are HTML Soup—a sloppy mix of old, new, and proprietary code. Yuck!
Standards, Cont.
- Future-proofs your web site
- Backward compatibility (for older browsers)
- Better printing capabilities
- Increased speed and reduced bandwidth costs
- Quickly and easily change appearance
- Improved search engine placement (SEO)
- Delivery to multiple devices
- Better accessibility
Accessibility
An accessible web page provides content that is available to any user with any browser or platform. More specifically, this means that the user can perceive, understand, navigate, and interact with the web page.
The major factors driving the need for accessibility are:
- Users with disabilities (visual, auditory, motor, cognitive)
- Inexperienced web users
- Users with limited technology
- May be legally required (such as Section 508 of the Rehabilitation Act, U.S.)
Dennis says, “Providing an accessible web site shows that you’re socially responsible”
Accessibility, Cont.
Benefits of Accessibility
- Provides equal access and equal opportunity to people with disabilities (visual, hearing, motor, cognitive).
- Increases potential use by more people—expands potential market share.
- Increases positive image.
- Possibly avoid significant legal costs.
- Decreases cost of having to provide information in alternative media formats such as alternative web sites, print publications, embossed Braille, computer disks.
Other topics
- Search Engine Optimization (SEO)
