Abstract: A reduced virtual keyboard system for text input on electronic devices is disclosed. Text input is performed by creating a tracing trajectory. Dynamic prediction solutions are created during the tracing process, thus avoiding the need for a user to complete the entire word trajectory. The system also allows a mixture of tapping actions and sliding motions for the same word. The system may comprise a Long Words Dictionary database having first letters corresponding to predetermined keys of the keyboard. Alternatively, the system uses a Dictionary and a database management tool to find long words.

Abstract: A reduced keyboard apparatus and method for use with small-sized communications and computing devices. Input via the keyboard is performed using fingers or thumbs. The keyboard is characterized by having no discrete boundaries between the included character spaces. The direction and the destination area of a keystroke do not have to be accurate and may correspond to a plurality of included character spaces. Each of the possible characters is provided with a probability value, continuously redefined according to the specific keyboard area activated by the keystroke. The input of a word is defined by a sequence of keystrokes corresponding to the letters of the word. Subsequent to the completion of a keystroke sequence, the apparatus and method determine the identity of the word through a disambiguation process based on area density distribution.

Abstract: A reduced keyboard system for text input on electronic devices, mainly for use with handheld touchscreen devices, comprising a virtual keyboard and an input device. The keyboard is preferably circular with three concentric circles. Text input is by placing the input device onto the key of the keyboard that corresponds to the first character of a word, sliding the input device to subsequent keys corresponding to subsequent characters of a word, and lifting the input device from the keyboard, producing a bi-dimensional input pattern. Keystrokes can be used instead of sliding motion in this case the input pattern is generated from the clicked keys. The system comprises a dictionary database comprising a plurality of classes containing words that have first and last letters corresponding to predetermined keys of the keyboard.
