Forgiving input for seniors: Seniors also have a harder time using unforgiving search engines and forms. We saw users thwarted because they typed hyphens in their search queries, and punished because they used hyphens or parentheses in a telephone or credit card number. In search queries, if a user types a dash or hyphen, ignore it by default. At the very least, detect it and specifically inform the user to remove it and search again. Accept dashes and hyphens as part of the string of credit card numbers. As much as possible, accept grammatically correct variations of your site’s URL. Consider registering several domain names.
