Embodiment Construction

[0028] The following definitions and descriptions provide background information pertaining to the technical field of the present invention, and are intended to facilitate understanding of the present invention without limiting its scope:

[0029] ATOMIK: Alphabetically adapted and optimized keyboard for mobile interfaces, optimized by an algorithm in which the keyboard is considered as a "molecule" and each key as an "atom". Atomic interactions between keys drive movement efficiency to a minimum. Movement efficiency is defined by the sum of all movement times between each pair of keys weighted by the statistical frequency of the corresponding letter. ATOMIK has also been adjusted alphabetically, creating a general tendency for letters from A to Z to move from the upper left corner of the keyboard to the lower right corner, helping users find keys they haven't remembered yet. ATOMIK is an exemplary virtual keyboard that can be used in combination with the present invention. ...

Abstract

A system augments stylus keyboarding with shorthand gesturing. The system defines a shorthand symbol for each word according to its movement pattern on an optimized stylus keyboard. The system recognizes word patterns by identifying an input as a stroke, and then matching the stroke to a stored list of word patterns. The system then generates and displays the matched word to the user.

Description

technical field [0001] The present invention relates generally to text entry devices for computers, and more particularly to text entry via a virtual keyboard for computer-based quick writing that utilizes shorthand gestures to augment stylus keyboard input. After glyphs are defined by all letters in a word on the virtual keyboard, shorthand gestures for vocabulary are defined as strokes formed sequentially by the user. Background technique [0002] Text entry constitutes one of the most frequent computer user tasks. The QWERTY keyboard has become accepted as the standard tool for text entry in desktop computing. However, the advent of handheld and other forms of pervasive or mobile computing requires alternatives. These devices have small screens and limited keyboards that limit the user's ability to enter text. Thus, text input has re-emerged as an important research topic in recent years. The two programs that have attracted the most attention are handwriting and styl...
