  • Error feedback system and method for correcting habitual keyboarding errors
    Patent number: 6419494
    Abstract: An error feedback system for use in correcting habitual keyboarding errors makes use of a set of markers for the keys that are mis-keyed. Each marker has an indicating side which can be identified by a user by feel and an adhering side which allows the marker to be adhered to the top surface of the key. The indicating side provides immediate feedback about a keyboarding error so that the error is not reinforced and repeat errors are minimized.
