Adaptive keyboard

The issue with current touch screen keyboards is that the characters are generally so close together that when composing a message, a user has a tendency to hit characters adjacent to those intended to select.

Current solutions to this problem include a system that recommends a word based on the letter typed. The issue with the current solution is that it does not deactivate characters, still making it possible for users to select the incorrect key.

The idea is to decrease the number of times a user hits the incorrect key when using touchscreen devices. The novel contribution is a system to reduce the active keys on the keyboard of a handheld device, based on the first character typed by the user, to reduce the risk of miskeying. Alternatively, the keys that are more likely to be used could be increased in size, while the less likely keys are accordingly reduced.

As the user types the first character of the word, the system shows all of the characters on the keyboard. After the user selects the first character, the system greys-out the entire keyboard, except for the characters that are potentially the next selected characters. This process of graying out all characters except those that are potentially the next character continues until the space bar or return key is selected. An additional button is present for re-activating the entire keyboard, making all keys selectable.

A second implementation is that instead of graying out the keyboard, t...
