Method and apparatus for accelerated entry of symbols on reduced keypad

本发明教导以下内容：一单个键可以支持多个有序组，而只需要在一个键的表面上视觉地显示每个组的一个子集，并且可以利用多重击键或预测方法、或同时两者来输入每一组的成员，而辅助键是一种用以选择有序组及进行多重击键功能的便利有效的方法。本发明的目的：有限的多重击键深度、减少的每符号按键次数、集中的焦点、可发现性、渐进的可发现性、能力、紧凑显示、及多重击键及预测文本方法的无缝集成，所有这些都可以通过明智地应用本发明来实现。 This invention teaches that a single auxiliary key 1006 can support a multiplicity of ordered groups 1003-1004 and that only a subset of each group 1003-1004 needs to be visually represented on the face of a key, and that either multi-tap or predictive methods, or both, can be used to input members of each groups, and that auxiliary keys 1005-1007 are a convenient and effective method to select ordered groups, and to perform the multi-tap function. This invention teaches: limited multi-tap depth, reduced keystrokes per symbol, discoverability, graduated discoverability, compact presentation, and seamless integration of multi-tap and predictive methods.
