The goal is to teach the patient about his or her disease, not about the computer. Also consideration must be given to the input device. Keyboards may be anxiety provoking to non-computer users, and their mere presence may create an obstacle that must be overcome. If possible, we try to place the keyboard out of sight. Input with a mouse has proven acceptable in our experience, but generally requires a brief period of instruction in order for most patients to use it efficiently.
Touchscreens seem to be the best input device for non-computer users.
It is quick and easy to demonstrate how a touchscreen is used. For both mouse and touchscreen input, command buttons should be large. Touchscreens, too, are much more efficiently navigated with larger buttons, allowing a larger margin for error. The primary goal is to eliminate barriers that stand between the patient and the information. One of the main purposes for using computers to educate patients is to make it easier for patients to obtain the necessary information.
