Visual Usability
Following is painfully abridged version of BCMA session notes. See http://zeroonedesign.com/usability/
Usability refers to the ease with which a User Interface can be used by its intended audience to achieve defined goals. Usability incorporates many factors: design, functionality, structure, information architecture, and more. (sitepoint.com)
Why Does Usability Matter:
- Poorly designed systems are hard to use
- Users are frustrated easily
- Frustrated users leave websites
- The Canadian Heritage Information Network 2004 Survey on museum visitors:
- 21% of those visitors living in Canada and 27% of those living outside of Canada used the Internet in preparing for their visit to a museum.
- In other words, more than one in five visitors will check out your virtual site before they check out your brick and mortar site.
- The survey found that "there is a strong positive tie between visits to museums' web spaces and in-person visits to museums. The more one visits museum web spaces, the more likely one is to visit museums in person."
- CHIN survey
- 68% visited a museum website to find information on recent exhibits
- 63% visited to search museum collections
- 60% visited to find special events
- 56% visited to find directions
Navigating the Website
Usability is about seeing the site from your visitor's perspective
Keep It Simple
- titles should be straightforward and should mean what you want them to mean
- buttons should be clickable and they should look like buttons
- people don't want to puzzle over things
Scan-o-rama
- When people read content on the web, they scan, they don't read
- Break pages into clearly definable areas
- Minimize noise - no movement, keep color choices to a minimum, tone down the exclamation points
- Make sure titles are prominent - big and bold
- Important information should be first on the page
- White space is your friend
Navigation
- People are usually trying to find something when they visit your site
- Navigation gives us something to hold onto in a site, it keeps us from getting lost
Writing for the Web
How do people read online?
- People who are looking for information online don't read, they SCAN
- Most people won't read instructions or click on HELP
- People read 25% slower on the screen
What to do if you really want your audience to read your content?
- Throw away 50% and then 50% again
- Provide a good headline and summary
- Provide link to more information or longer document
- Stick to Sans serif fonts (Arial, Helvetica, Verdana) - they are the most legible
How to create a website that is SCAN friendly?
- Create heading and subheadings
- Be consistent
- Use font and/or colour to offset headings
- Use background colours in table cells
- Organizing Content for Viewing
- In columns, not rows
- By category if appropriate
