I never realized that a simple error message would require so much thought, especially when considering the needs of an older audience. FamiliLink’s user interface is specifically designed for older adults and therefore requires ongoing usability testing. One of our early learning points was the significant importance of error message for our older users. The language and text has very specific requirements. Our first usability study indicated that several of our error messages describe a problem but didn’t provide solutions. Older Users like to understand what to do to fix the problem (for instance, the statement “invalid user name” could be very frustrating to a senior user…what do I do about an invalid user name? When older users do not know how to solve problems that arise, it can leave them frustrated and unable to move forward. They already approach the computer with some fear and intimidation. So it is vitally important that error messages be proactive and offer the elderly users with potential solutions.
Some additional research showed similar results:
· Error messages are often hard to read, either because the wording is obscure or imprecise, or the message’s placement on the page is easily overlooked. Simplicity is even more important than usual when seniors encounter error handling: The message should focus on the error, explain it clearly, and make it as easy as possible to fix.

· As older adults move onto the Web, many report that maneuvering online can be intimidating. Take George McKinney, a 73-year-old retired structural engineer in San Diego who uses the Internet to research stocks. He often shuts down his computer in frustration, for example when he enters a stock symbol and gets an error message that doesn’t tell him exactly what he did wrong.
Mr. McKinney’s online experience is common among older adults. “They can often be stumped by even the smallest problem,” says Jakob Nielsen, a co-founder of Nielsen Norman Group in Fremont, Calif., a consulting firm that specializes in optimizing the user experience on the Internet.

I did a little research myself and went to some services online that target older adults like Finerday, AARP and Commino. Deliberately I tried to log in with mistakes to see what kind of error message would show. Here are some examples:
· Sorry, this username is unknown.
For seniors this error message is too abbreviated and there is no potential solution what to do next. Why is it unknown?
· Please enter a valid e-mail address and password. This error message only provides the solution. Seniors like to know what they did wrong. This message could be frustrating because I will think to myself…I did enter an email address and password.
· You ID or password you typed is incorrect. Please Click OK and then retype the your ID and password, or Register if you haven’t already done so. This error message is better for seniors as it indicates what was wrong.In terms of wording, seniors are insecure when using the computer and words as incorrect are sometimes perceived intimidating. Your ID is not recognized is probably better received. It also probably should be shorter.
More on error message text I found at this website:
· Make sure the error message identifies the related field with the name as it is written in the label for that field.
· Do not use complicated words
· Describe what the user should do to correct the error, especially if it could be difficult to understand.
· Make it clear if there were more than one error so that the user can correct all errors at once.
Summarizing: Error messages especially for older adults need to state the problem first followed by the possible solution and what to do next. The text needs to be as short and crisp as possible and positive. Not using terms as not valid incorrect etc. At FamiliLink we are working hard to clean up all our error messages and so our senior users have a positive and rewarding user experience.
