For users who cannot use a standard keyboard or pointer, scanning options are available. The scanning patterns for existing or newly created keyboards can be altered to suit the user's preferences or the situation. The size of any keyboard and its keys can independently be adjusted. In the Spring of 1999, AHF filed a patent application on what might be the most significant advance in assisted keyboard entry since word prediction. Then, the keyboard is updated to help identify those keys that are most likely.
Various options are available.
In one mode, unlikely keys are removed from the keyboard. In another mode, the color of unlikely keys is changed and they remain active. It is expected that Smart Key technology will be useful to almost anyone using on-screen keyboards, but that the greatest advantage will be for persons using scanning keyboards because only the likely keys get scanned. This script will solicit comments, suggestions, criticisms, reactions, etc. that the user might have for each mode. The subject's task is to type the word as quickly and accurately as possible.
