Definitions

  • the present invention relates to a touch type character input device, and more particularly, to such a device for expediently inputting characters through a touch type user input device such as a touch screen or a touch pad.
  • a representative example of a device for inputting characters (which may be also referred to as a "letters") on a touch sensitive basis is a personal digital assistant (PDA).
  • PDA personal digital assistant
  • GUI graphic user interface
  • POS point-of-sale
  • ATMs automatic teller machines
  • Such a touch type user input device detects a coordinate of a contact point on a screen where a user touches or whether or not he or she touches the screen using an infrared-ray, a resistor film, a supersonic wave, etc.
  • a user's finger or a stylus pen In case where the touch type user input device is used, a user's finger or a stylus pen.
  • a stylus pen is mainly used for a small-sized device so that a user can more precisely select a point indicated within a touch region on the screen due to a limited size of an input region of the touch type user input device, i.e., a touch sensitive region.
  • selection-based input method a method of selecting a unit character provided on a touch screen
  • writing-based input method a method of directly writing a character in a designated region of a touch screen to recognize the character
  • Examples of the writing-based input method include a graffiti input method which has been proposed and used by Palm Co., i.e., a PDA manufacturer, a character recognition system used in Windows CE, etc.
  • a writing-based input method has a shortcoming in that it is difficult to characters and there is a high possibility that a recognition result may be erroneous.
  • PDAs manufactured by Palm Co. it is required that a separate sticker peculiar to the graffiti input method should be attached on the PDA. Since it is required that a separate window where a user can write a desired characters be included on a touch screen or be configured of a touch pad in a separate position of PDA, the touch screen is not used efficiently and a device becomes large in size.
  • Examples of the selection-based input method include a method of inputting characters by depressing a corresponding key arranged on a transparent virtual keyboard displayed on a touch screen such as Korean Patent No. 509198 shown in FIG. 1, and a Cirrin method of inputting desired ones of English alphabet characters arranged in a donut shape using a stylus pen as shown FIG. 2.

  • Such a conventional selection-based input method entails problems in that since a number of characters must be disposed or a lot of submenus must be separately provided in a limited region for the purpose of their selection, in case of using a multiple of letters such as the English alphabet consisting of a total of twenty-six letters or the Korean alphabet, i.e., Hangeul consisting of a total of twenty-four letters, a spacing between adjacent letters is inevitably decreased, and hence it is difficult to accurately depress a desired character, which results in an increased generation of erroneous entry.

Abstract

Cette invention concerne un dispositif de saisie de caractères de type tactile permettant de saisir rapidement des caractères par l'intermédiaire d'un dispositif de saisie utilisateur de type tactile, tel qu'un écran tactile ou un pavé tactile. Ce dispositif de saisie de caractères de type tactile comprend une zone tactile dans laquelle une coordonnée est désignée ou un caractère est sélectionné au moyen d'un doigt ou d'un outil de manière à saisir le caractère ou la coordonnée sur un dispositif principal. En outre, ce dispositif de saisie comprend: une première zone de manipulation définie par une première courbe fermée à l'intérieure de la zone tactile, une seconde zone de manipulation définie par une seconde courbe fermée de manière à entourer la première zone de manipulation à l'intérieur de la zone tactile, la seconde zone de manipulation étant la zone restante autre que la première zone de manipulation dans la zone entourée par la seconde courbe fermée et constituée de plusieurs secteurs de caractères chacun affecté d'un caractère représentatif correspondant; une section de traitement des saisies conçue pour désigner un caractère en cours, pour fixer un mode de langue de saisie ou modifier la position d'un curseur en réaction à un signal tactile généré dans la première et dans la seconde zone de manipulation; et une section d'affichage de caractère conçue pour afficher le caractère désigné par la section de traitement des saisies.
