Definitions

  • the present invention concerns a keypad which is small-sized and with which it is possible to write text more quickly than with a conventional keypad composed of push-buttons.
  • the text may include letters A-Z or characters belonging to another alphabet or character set.
  • the keyboards of the computer include the characters A-Z and a set of other characters. Each letter A-Z has its own key and the placement of these keys is fixed. The keys are in three lines, so that the first six letters are: 'q', 'w', 'e ⁇ V, 'f, 'and y', from which the keyboard has obtained the name "qwerty". Also some mobile station models contain a qwerty keyboard. Because a qwerty keyboard requires 26 keys, the mobile station models include at least 26 keys. Usually, a qwerty keyboard also includes a numeric keypad containing the keys 0-9. An aim with mobile terminals is to make them small- sized and light in weight. However, a qwerty keyboard must be large enough that it can be operated easily.
  • numeric keypad including ten keys, which is used especially in telephone terminals.
  • a key intended for entering the number 1 could be termed the 1- key
  • a key intended for entering number 2 could be termed the 2-key, etc.
  • numeric keypad 0-4 letters are positioned in one key, so that the 0- and 1- keys contain no letters, the 7- and 9-keys have four letters, and the rest of keys contain three.
  • FIG. 1 shows a known keypad that is used so that a letter is entered by pressing a certain key on to four times.
  • the letters A, B, and C are placed with the 2-key 11.
  • Letter A is entered by pressing the 2-key once
  • letter B is entered by pressing 2-key twice
  • letter C is entered by pressing 2-key three times.
  • the other keys of the keypad are operated in the same way.
  • the time period between the first and the second key pressing should be long enough. For example, when typing two A-letters the 2-key should be pressed and then a pause, after which the 2-key should be pressed again. If the said pause is too short, the key pressings result in one B-letter, not two A-letters. Thus, the pause should be long enough to obtain the letters needed. However, the pauses between key pressings delay writing, of course.
  • the known keypad is suitable for the use of a relatively small character set. In English-speaking countries the character set contains the letters A-Z, numbers 0-9, and certain punctuation marks, such as the period, the question mark, and exclamation mark.
  • an alphabet contains more letters than A-Z.
  • one character corresponds to a syllable. These languages, such as Korean, are termed a syllabic language.
  • one character corresponds to a word. For example, in Chinese, the language spoken by the majority of people in the world, one character corresponds to one word.
  • a computer mouse is used by moving a cursor on the screen pressing a mouse button once (click) or twice (double-clicking). In no application is a mouse button pressed three times ("triple-clicking"). For physiological reasons it is easier for a human being to distinguish between single clicking and double-clicking than between double-clicking and "triple-clicking".
  • a patent document EP0608682 describes certain logic with whereby a letter group is first defined and then a letter's placement in the letter group. For example, when using a keypad shown in as FIG. 1 letter A is entered as follows. First the 2-key 11 is pressed, because letter A is placed in a letter group ⁇ A, B, C ⁇ . Then 1-key 12 is pressed, because A is the first letter in the letter group. Letter B is entered by tapping the 2-key twice, because letter B is the second letter in the letter group. Correspondingly, each letter of A-Z can be entered by two key pressings.
  • the prior art also contains solutions whereby conventional keys are replaced with keys having at least two positions for entering letters.
  • a key can be moved in a first direction resulting in a first letter.
  • the key can be moved in a second direction resulting in a second letter, and so on.
  • FIG. 2A shows a key of a keypad described in patent document WO99/37025.
  • the said key is oval and can be moved to the left and to the right.
  • the key has a primary mode and a secondary mode; the mode is selected by pressing a mode key.
  • the primary mode for example, number 7 when a key 201 is pressed.
  • the secondary mode the key 201 results in letter A when the left edge 202 of the key is pressed, and the key 201 results in letter B when the right edge 203 of the key is pressed.
  • FIG. 2B shows another key described in patent document
  • the said key 204 is square having four corners/edges. In the secondary mode the key results in four various letters depending on which corner 205, 206, 207, or 208 is pressed.
  • FIG. 2C shows two keys of a certain keypad described in patent document WO99/37025. Those keys are triangular. When comparing keys
  • keys 209 and 210 to keys 11 and 12 we can say that the first-mentioned keys 209 and 210 are larger, because both of them should result in three various letters depending on which corner 211 , 212, or 213 a user presses.
  • the keys 209 and 210 should be quite far from each other in order to elimi- nate typing errors. For example, when a user presses the corner 212, key
  • a conventional key has only one position, i.e. "inward", for entering various keys.
  • a key having at least two positions for entering various letters is termed a multi-position key.
  • the invention is closely related to multi- position keys.
  • the first drawback is that the use area for a multi-position key is larger than the use area for a push-button key, wherein the use area of a key is the surface which is intended for pressing that key or which is difficult to avoid touching when pressing the key. If a key includes edges/corners, such as the corners 211 , 212, and 213 of the key 210, the use area contains the entire area between the said edges/corners.
  • the second drawback of the prior art is that the multi-position keys cannot be located close to each other, because they need a relatively large safe area to avoid typing errors.
  • the safe area of a key is the use area of the key plus some extra spaces surrounding the edges/corners.
  • key 210 has a safe area 214.
  • the size of a user's finger affects the size of a safe area.
  • the keypads composed of multi-position keys is relatively large.
  • the objective of the invention is to define a keypad, a qwerty key- board, or some other keypad/keyboard, so that it is small-sized and quick to operate.
  • the keys of a keypad in accordance with the invention have at least two directions for entering characters, i.e. the keys are adapted to move in at least two directions.
  • a key of the keypad has one edge through which the key is moved various directions.
  • protrusion refers to an edge, a corner, a top, a border, or an extension of a key. Because a key has only one protrusion, the use area of the key is smaller than the use area of the prior art multi-position key. Actually, the use area of the key is even smaller than the use area of a conventional key.
  • the protrusion of a key may be relatively short and thus the trajectories of the key are also short. Therefore the safe areas of keys are small and the keypad composed of the keys is small-sized.
  • One embodiment of the invention is a numeric keypad in which each key is a joystick having at least two directions, so that moving a joystick in a first direction results in a first character and moving the joystick in a second direction results in a second character.

  • a text is composed of a limited amount of characters differing from each other. These characters compose a character set.
  • Entering text in accordance with the invention involves a character set that is divided into at least two subsets, so that at least one subset contains at least two characters.

  • any other way of dividing letters into subsets is possible.
  • a key of a keypad preferably has one "middle” position and four “non-middle” positions. These "non-middle” positions could be “upward”, “downward”, “to the left”, and “to the right”. Then letter A can be entered by moving the 2-key from the middle to the left.
  • the middle position is an exam- pie of a position that is termed "the basic position”. The use of a key is fluent if the key is adapted to return to its basic position when the key is not touched.

  • the use area of the keys is small, for example, the use area 33 of key 32 is small. Therefore only one character is located in key 32, i.e. number 2.
  • the other characters A, B, and C, which are entered by using the 2-key, are located in the cover of the keypad 34. Because the belonoid keys 31 and 32 are short, their trajectories towards each other are also short and thus the keys can be located close to one another.
  • the safe area 35 of the key 32 with the safe area 214 of key 214, we can say that the safe area 35 in the smaller one.

  • the prior art multi-position keys have several protrusions for entering letters.
  • Alcatel uses a joystick selector in a Mobile 100 telephone set, but not in the numeric keypad of the telephone set. In a Mobile 100 telephone set the joystick selector is intended for using the menu system of the telephone set. Therefore a joystick is not a new element in a telephone set, but it is a new element in a keypad intended for typing text.

Abstract

L'invention concerne un clavier numérique sur lequel les touches 0-9 sont remplacées, à titre d'exemple, par des touches en forme de manette de jeu, chaque touche/manette de jeu pouvant prendre au moins deux positions, et chaque position donnant un caractère différent. Les différentes touches présentent une seule protubérance qui permet le passage d'une position à l'autre. Le fait qu'il existe une seule protubérance et que la surface de cette protubérance soit inférieure à la surface correspondante d'une quelconque touche connue à positions multiples permet de rapprocher les touches les unes des autres, ce qui confère sa petite taille au clavier. Par ailleurs, on décrit un clavier d'ordinateur susceptible d'être composé de manettes de jeu ou d'autres types de touches à positions multiples ayant une protubérance qui permet de saisir des lettres et autres caractères.
