Usability Quote of the Day

May 23, 2012

There's something very odd going on here. If designers made completely unrealistic assumptions about the physical world when designing technology, then we would blame them (and likely sue them) for technical incompetence. Yet when they make grossly unrealistic assumptions about human nature... we don't blame the designers, we blame the unfortunate people who are just trying to do what the design requires. -- Kim Vicente, The Human Factor, p. 45.    (via interaction-design.org)

Disabled web users rank their usability priorities

New accessibility results for disabled users ...

"Effective in-site search, good navigation, and clear, well-constructed content are the most important usability issues for disabled internet users, according to new research which also found many visually impaired users rejecting the importance of ALT tags.

User experience consultancy User Vision surveyed a cross section of 208 internet users throughout the UK with impairments which affect the way they use the internet, comprising the visually impaired/blind, hearing impaired/deaf, physically disabled, and those with dyslexia/learning difficulties.

The users were asked to rank, in terms of importance, the factors which aid their ease of use when online. Clarity of content – using straightforward language and a clear, simple layout – was regarded by 88% as ‘very important’. Good navigation – the ability to know where you are within a site – was regarded as very important by 65%, followed by the use of meaningful and clear hyperlinks (63%).

Two of the three factors traditionally perceived as the fundamental accessibility issues have become comparatively less significant. Good use of ALT tags – which provide text alternatives for images – was only regarded as ‘very important’ by a third of respondents Surprisingly, among the visually impaired users, 25% found ALT tags not important at all."   continued ...   (Via OUT-LAW.COM)
