People with Physical Difficulties Use the Web

Although there is a wide range of physical difficulties, focus your efforts on keyboard and mouse input because these are the primary input modes for computers for the near future. A customer with a physical disability might not be able to use a keyboard effectively, or even at all. The same is true for use of a mouse. Here's how to address these problems:

  • Test if your Web site can be used without a mouse. Determine whether a visitor could use just the keyboard to navigate through your Web pages.

  • Minimize the amount of typing a visitor has to do. For example, a common technique in QUICK-FLOW CHECKOUT(F1) is to have customers enter their shipping address and then be able to indicate that this is also the billing address just by clicking a button with the mouse. This is much simpler than having a customer type in the same thing twice. Another way to minimize the input required of customers is to save the information that they typed in on a previous visit to the site, providing them with a QUICK ADDRESS SELECTION(F4), a QUICK SHIPPING METHOD SELECTION(F5), and a streamlined PAYMENT METHOD (F6) the next time they purchase something.

  • Make sure that your navigation elements are large enough to see clearly. Avoid links that are in small fonts and links that use small images. These elements are just too difficult to click on with a mouse. This caution applies to NAVIGATION BARS(K2), ACTION BUTTONS(K4), and OBVIOUS LINKS(K10).
