The use of row/column scanning, a technique for accessing a large number of selections with a single volitional action, is considered for individuals with disabilities. It is explained that such a scanning approach is particularly useful for those with only one volitional action, or those, such as people with cerebral palsy, who have pointing skills but need access to devices at all times without expending excess energy. Essentials for row/column scanning are listed, and common oversights are explained, including inefficient display panel layouts. The design of a more efficient row/column scanning device is described, and advantages (such as consistency) and disadvantages (such as the need for sophisticated tracking skills on the user's part) of the technique are noted.
