I don’t know how it happened but somewhere along the line Headscape has ended up doing a disproportionately large amount of design work for an older audience. Perhaps this is something to do with the fact that we are an aging population with the number of people over 60 dramatically out numbering those under 16. Whatever the case, the fact that I design regularly for an older audience meant that this report from webCredibles caught my eye.
webCredibles compared 16 usability test sessions, 8 using an older audience (over 65) and 8 with a younger audience (under 40). The comparison led to a number of interesting observations as well as some excellent advice on designing for an older audience.
Their recommendations (with which I totally agree) included:
- Designers should investigate innovative ways to communicate the fact that a page had not finished and requires scrolling
- Technical terms should be avoided if possible – and where they have to be used, a clear explanation must be easily accessible (including examples wherever appropriate)
- Links should be identified in a consistent and obvious way (e.g. blue, bold, underline, red on mouse-over)
- The attention-grabbing features on a page (e.g. headings, pictures, icons, instructions and bullets) should be links
- Visited links should change colour
- Provide an HTML-version of as much content as possible and do not require users to install software (even Adobe Acrobat) in order to be able to access information
- Make content as concise and clear as possible – consider providing two versions of the same content (‘simple’ and ‘detailed’) and allow users to decide which they want to access
- Sites should provide a ‘Make the writing bigger’ link with accompanying illustrations/icons and always use high contrast to display text e.g. black text on an off-white background (N.B. using an off-white background is preferable to white because it reduces the chances of eyestrain for people who are slow readers)
- Provide explicit instructions by using the imperative forms of verbs (e.g. ‘Go to more details on…’, ‘Find a…’, etc.)
Dealing with scrolling
All good advice and particularly relevant for me as I am currently working on a site aimed specifically at the over 65 market. One particular problem that I am working on is how to encourage users to scroll. It is interesting to note that although webCredibles raise this as an issue they offer no real solutions.
One possibility I am currently working on is adding a fixed position (doesn’t move when the page scrolls) message explaining there is more content below the fold. When the user clicks the message, the page automatically scrolls down revealing more content. There is a whole bunch of usability and technical problems associated with this, but it might just be a viable solution. I will let you know if I get it working.
I would be interested in hearing your thoughts on encouraging scrolling. If you have any great ideas, post a comment here.
