Definitions

  • This invention relates to a non-predictive text input apparatus and method suitable for keypads having a limited number of keys and a plurality of Letters assigned to each of a set of keys, wherein a desired Letter may be selected from one of a plurality of Letters on any of the Letter keys, using one Letter-key stroke in conjunction with a Smart Key to define the Letter
  • This invention has particular but not exclusive application to devices for typing text in miniature hand-held computer apparatus such as Personal Digital Assistants (PDAs); cellular phones; portable email message communication devices; TV remote control devices; two-way pagers; hand held, pocket, and shoulder carry computers; simple translators, and communication aids for or by persons having limited physical capabilities.

  • the standard size qwerty keyboard has good ergonomics, but as its size is reduced typing becomes more difficult.
  • the miniaturization of keyboards means that the keyboards have to be poked carefully with fingertips, or with a pointed object. Reducing the number of keys means that, for language input and other basic text functions which have to be provided each key has to become a multi-purpose key. With known solutions it is impossible to type with ease and speed similar to that when using a standard size qwerty keyboard.
  • Alternate apparatus used to input characters into miniature devices include voice recognition, digitizing pads and other devices for recognizing handwriting, and virtual keyboards displayed on screen for use with pointing devices.
  • Speaker independent voice recognition is not yet perfected and suffers from problems of ambient noise, especially in a mobile device application, and user voice security. It is language, and dialect specific. It does not, and never will provide a total global solution. Some other form of input will always be required for editing text imperfectly entered by voice.
  • Keypad applications with multiple key tapping, or cursor selection on screen are slow and tiresome for composing text. The program must pause between key taps to determine if the last Letter displayed is the desired one, or whether the operator will continue to tap the key. They do not provide the best solution for many languages.
  • the present invention is capable of offering the possibility of using almost all of the world's languages in the one device with very small memory requirements. For each language used it is only necessary to store that language's alphabet/syllabary. Many foreign words, not normally in a language-specific database can be simply entered as on a standard full-size keyboard.
  • Groups of languages using the same alphabet letters may be used in the same device without having to install any frequency of use weighting, dictionary of words or prefixes, proper nouns - personal or town/country names, street addresses, email addresses, URLs, medical terms and other technical words, non-words, slang words, and abbreviations.
  • the present invention makes it possible to use the one device for almost all languages, including Asian languages, as they are spoken, simply by installing and accessing the Letters of their alphabets.
  • Asian languages can be used in syllabic form to communicate phrases and sentences which are understood in context just as in speech.
  • One predictive text input device has for example eight possible words for the key sequence 22737 which in order of frequency of usage are: cases, cards, bases, acres, cares, bards, hares. If the word bares was required it would take an additional six strokes to retrieve it - a total of eleven strokes.
  • One method, which uses prefixes of two or more letters to predict words has the disadvantage that the first, and most important letter to be typed is not a prefix. This means that if the desired first letter is not the most commonly used of those on the key pressed extra strokes must be pressed.
  • the letters shown in the first column are said to be the most likely to be used as the first letter of a word in English language. The next most likely are shown in the second column; next in the third column, and next in the fourth column. The number of keystrokes to successfully enter the first letter of the desired word is shown above the columns.
  • Another predictive input system uses an "auxiliary" key, which is pressed in conjunction with a letter key to choose one fixed letter from each of the groups of letters on each of the keys on the telephone keypad These chosen letters are typed by holding down the auxiliary key while pressing the key with the intended fixed letter
  • auxiliary key For English language it is claimed the best letters to fix on the keys are c e h 1 n s t and y. Letters which are not "c e h 1 n s t y" letters are typed by pressing the keys with the intended letter, without holding down the "auxiliary” key until the desired letter is retrieved, or the predicted word formed.

Abstract

L'invention concerne un appareil de saisie adapté pour claviers possédant un nombre limité de touches et plusieurs lettres assignées à chaque ensemble de touches. Une lettre désirée peut être sélectionnée à partir d'une des lettres sur une touche quelconque en utilisant une touche lettre conjointement à une touche intelligente pour définir la lettre. Les touches intelligentes sont identifiées par un nombre, ou d'autres éléments d'identification tels que la couleur, les associant à la position séquentielle des lettres affichées sur les touches lettres, et sont pressées conjointement à la touche lettre à laquelle est assignée la lettre désirée. La frappe par simple toucher sur un clavier limité est possible après une courte période de pratique.
