[0049] The term efficient typing or good performance typing, as used herein and which are used interchangeably, refers to typing a word on a keyboard, with minimal key strokes, increasing the speed and accuracy.

[0050] While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and the above detailed description. It should be understood, however, that it is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.

[0051] An aspect of the present invention is to provide screen layouts for maximum efficiency of screen area usage with an integrative typing of groups of letters and of letter-by-letter typing aided by embedded prediction functionality Using the same touch-screen area for the presentation of predicted words, while typing a word and for most command function keys in between words, is also an aspect of this invention. It takes advantage of the nature of the typing process, in order to save up to third of the area used by ordinary key-boards. According to the present invention, the command keys used for functions such as signs, letter-by-letter or number typing, exit or editing functions, are presented after approval of a predicted word, or before starting typing of a new word using word prediction mode, at the same area where predicted words are presented while typing the word. Under certain embodiments, such as when swiping is technically not feasible, while typing a key, all letters included in this key are initially presented in the area allocated for predicted words, or in the entire keys area. So that the user can select one of them for letter-by-letter typing.

[0052] Reference is now made to FIG. 1, which is a schematic illustration of an example reduced keyboard disambiguating system 100, according to embodiments of the present invention. Reduced keyboard disambiguating system 100 provides efficient typing using fewer keys, thereby occupying a smaller screen space, which is desirable in small devices. System 100 includes a processing unit 110, memory 120 including data store in a database 122 and/or memory 120, a screen 130 and an input device 140 which may either be a portion 132 of screen 130, in the form of a touch screen, or another input device mapped to fields represented on the screen. Optionally, system 100 further includes an audio feedback device 150.

[0053] Reference is now made to FIG. 2, which is a schematic illustration of an example reduced keyboard disambiguating systems comprising: a letter layout region 2.1 configured to generate single characters and/or a group of characters; a commands or predicted words layout region 2.2 configured to generate commands, predicted words, or single letters while in the usage of the system by a user. The layout can facilitate presentation of predicted words, and if, the predicted word is generated, facilitate presentation of function commands, such as send, screen swap, or exit; a written text layout region 2.3 configured to display the textual output by the system; and special commands layout region 2.4 configured to facilitate predefined commands options, such as shift, delete, space and others. Under certain embodiments the preferred predicted word is presented within written text layout region 2.3 in order to free space in predicted words layout region 2.2 for presentation of one more predicted word.

[0054] The present invention will now be described in terms a reduced keyboard for the English language, but the present invention is not limited to reduced keyboards for the English language and applies to reduced keyboards for substantially any language.

[0055] Reference is now made to FIG. 3, which is a schematic illustration of an example reduced keyboard disambiguating system according to the method of the present invention. As referenced in FIG. 2, a user employs the letter layout region 2.1 to choose via keys a single letter or a group of letters. The letter is then added to the group of letters that were typed in before. The prediction module generates a list of all the words including said new letter or a group of new letters, based on their usage in the text of the relevant language, and if such words exist, they are presented on the commands or predicted words layout region 2.2. Each letter key in the letter layout region 2.1 is capable of immediate/instantaneous production of both a group of letters for an effective word-prediction typing, or a single letter, and is designed to visually instruct both possibilities. If the user finds the word he/she is looking for in the commands or predicted words layout region 2.2, he/she can then select it by any method of tapping, scrolling or other method of selection, and the word is directed to be presented on the written text layout region 2.3. If the user does not find or does not select the word he/she is looking for in the commands or predicted words layout region 2.2, he/she can then proceed further to choose an additional single letter or a group of letters via the letter layout region 2.1. The system then recalculates the predicted words and presents the new list in the commands or predicted words layout region 2.2. If the user deletes a letter, the system reverses the prediction function and brings previously predicted group of letter on the written text layout region 2.3. If the user deletes all letters in a word the system presents commands in the commands or predicted words layout region 2.2,

[0056] Reference is now made to FIG. 4, 4a-d, which are schematically illustrate a method for integrated reduced keyboard disambiguation and touch-based precise character selection, based on generating a single letter and/or a group of letters, in different display layout facilitations. Each of the keys is divided by symmetrical axes to include a half of the number of characters, thus either letters or other characters, for example: in FIG. 4a presented a horizontal axis 401, a first diagonal axis 403 and a second diagonal axis 404 (based on roughly 60 division); in FIG. 4b presented a vertical axis 402, a first diagonal axis 403 and a second diagonal axis 404 (based on roughly 60 division); in FIG. 4c presented a horizontal axis 401, and a vertical axis 402; and in FIG. 4d presented a vertical axis 402 only. As presented in FIG. 4, the characters (no more than 6) are distributed based on the key layout, on each side of the symmetrical axes. For selecting a group of all the letters on the key, including the right letter, the user selects the key including the right letter by any method of tapping, scrolling or other method of selection, for example by pressing a key 422 and choosing from E F G H I J group of letters. For selecting a single letter, the user selects the right letter by the method of swipe on the key in the direction of the right letter, for example swiping on the key 422 that is presented in details in FIG. 4a in the direction of 416 generates the letter H. For example, as presented in FIG. 4, if the user already typed the letters KEY the words KEY, KEYS, KEYBOARD and are presented in Written text 2.3 zone and in Commands or predicted words zone 2.2 now if the user presses on the key 424 in order to add a fourth letter to words starting with KEY, one letter of T, S, R or Q should be added and the predicted word that is displayed is KEYS. If the user swipes on the key 421 in the direction 413 of key 4a in order to locate words starting with KEY, and further there is a letter B, the predicted word that is displayed, is KEYBOARD.

[0057] Reference is now made to FIG. 5, which schematically illustrates a method for integrated reduced keyboard disambiguation and touch-based precise character selection, based on swipe angle direction detection and correction. The system facilitates a swipe angle range wherein two relevant letters are used by the prediction module in order to identify possible predicted words, based on the proximity of the swipe. For example, if the user swipes in the direction of a letter, there is a chance of getting its proximal letter, if the swipe was not precise, such as, if intended, swiping in the angle 0 to 60 the user receives letter G and swiping in the angle 60 to 120 the user receives letter F, however in the angle 61 there is a chance of getting letter F instead of intended letter G. For example, the system defines proximal angle of 10, wherein in the angle range of 10 to 55, the user receives letter G, in the angle range of 65 to 115 the user receives letter G, and in the angle range of 55 to 65 the user receives both letters G and F, while the prediction module generates predicted words based on both of the letters. Under certain embodiments the closer the direction is to one of the two letters, the higher probability given to a predicted word based on this letter and not the neighboring one. For example, 55 will be interpreted by the prediction module as the selected letter was most likely E, and less likely to be F while for 65 this will be the opposite.

[0058] Reference is now made to FIG. 6, which presents a table that provides a list of letter combinations presented on selected keys sets, according to embodiments of the present invention. For a square smartwatch display, the system facilitates: a layout with a horizontal axis, configured to generate 5 letter keys and 1 commands key, in alphabetical order sab1; a layout with a horizontal axis, configured to generate 6 letter keys, wherein commands key is facilitated instead of punctuation signs, in alphabetical order sab2. For a round smartwatch display, the system facilitates: a layout with a horizontal axis, configured to generate 6 letter keys and 2 commands key, in QWERTY order rq1; a layout with a horizontal axis, configured to generate 5 letter keys and 2 commands key, in QWERTY order rq2; a layout with a horizontal axis, configured to generate 5 letter keys and 2 commands key, in alphabetical order rab1; a layout with a horizontal axis, configured to generate 6 letter keys and 2 commands key, in alphabetical order rab2; a layout with a horizontal axis, configured to generate 5 letter keys and 2 commands key, in alphabetical order rab3. For vertical smartwatch display, the system facilitates: a layout with a vertical axis, configured to generate 5 letter keys and 1 commands key (3 keys in 2 lines), in alphabetical order vab1; a layout with a vertical axis, configured to generate 5 letter keys and 1 commands key (2 keys in 3 lines), in alphabetical order vab2; a layout with a vertical axis, configured to generate 5 letter keys with horizontal axis each, and 1 commands key (2 keys in 3 lines), in alphabetical order vab3. For a display with a wider moderate-width keyboard comprising 8 keys, the system facilitates: a layout with 7 letter keys with 4 characters in each one of them and 1 commands key, in alphabetical order mab1; another layout with 7 letter keys with 4 characters in each one of them and 1 commands key, in alphabetical order in rows mab2. For a display with a wide keyboard comprising 10 keys, the system facilitates: a layout with 4 characters keys, configured to generate 8 letter keys and 2 commands key, in QWERTY order wq1. For a display with a very wide keyboard comprising 14 keys, the system facilitates: a layout with 2 characters keys, configured to generate 13 letter keys and 1 commands key, in alphabetical order xab1.

[0059] Reference is now made to FIGS. 7, 7a and 7b, which schematically present an example of reduced keyboard disambiguating system employing single letter selection without the swipe method of selection, according to the method of the present invention, the system comprising: a letter layout region 7.1 configured to generate single characters and/or a group of characters by the method of long tap on the key and/or two or more sequential quick taps on the key; and/or an alternative distinct way to a long tap of key selection, a commands or predicted words layout region 7.2 configured to display a single character and/or a group of characters; a written text layout region 7.3 configured to display the textual output by the system; and special commands layout region 7.4 configured to facilitate predefined commands options, such as shift, delete, space and others. When the user selects a key in the letter layout region 7.1 by the selection method in a form of long tap on the key and/or two or more sequential quick taps on the key, and/or an alternative distinct way to a long tap of key selection, all the letters/characters are presented on the commands or predicted words layout region 7.2 (no change to the text in the written text layout region 7.3), as presented in FIG. 7a. The user then selects the right letter that is then added to the existing text in the written text layout region 7.3. The prediction module generates a list of all the words including said new letter or a group of new letters, based on their usage in the text of the relevant language, and if such words exist, they are presented on the commands or predicted words layout region 7.2. Reference is now made to FIG. 7b, which depicts an example of letters layout, utilizing a full-mode presentation of all available letters in a key, after selection of a long tap of this key 202 of FIG. 12. The presented layout utilizes the keys space available for the user to select characters in an easier and more precise method of tapping, scrolling, eye gazing, or any other method of selection.

[0061] Reference is now made to FIG. 9, which schematically illustrates a system for integrated reduced keyboard disambiguation and touch-based precise character selection, based on prediction module word generation, comprising, as referenced in FIG. 4: a letters generator module 9.1 configured to generate a single letter or a group of letters; a letters accumulator module 9.2 configured to facilitate the sequence of the single letters or the group of letters added by the letters generator module 9.1, based on their selection order; a processor 9.3 configured to extract said sequence of the single letters or the group of letters added by the letters generator module 9.1, transmit said sequence to a words database 9.5 coupled to memory medium, and perform cross-reference against the words stored in the words database 9.5, configured to store words based on their statistical usage in the relevant language, to locate words that correlate to the sequence of the single letters or the group of letters added by the letters generator module 9.1, based on their selection order. The processor 9.3 then sends said chosen words to predicted words module 9.4 configured to present words based on the performed cross-reference against the words stored in the words database 9.5.

[0062] Reference is now made to FIGS. 10a-b, which schematically illustrate examples of a system for integrated reduced keyboard disambiguation and touch-based precise character selection, based on letter accumulator module letter facilitation. As referenced in FIG. 9, in FIG. 10a the letters accumulator module 9.2 is configured to facilitate the sequence of the single letters or the group of letters added by the letters generator module 9.1. In the present example, in the first step the letters accumulator module facilitates letters U V W X Y Z, in the second step the letters accumulator module facilitates letters E F G H I J, in the third step the letters accumulator module facilitates letters A B C D, in the fourth step the letters accumulator module facilitates letters Q R S T, and in the fifth step the letters accumulator module facilitates letters A B C D, which transliterates in the predicted word zebra. In FIG. 10b, upon the selection of a letter Z, the letters accumulator module facilitates a letter Z, in the second consequent step the letters accumulator module facilitates letters E F G H I J and upon the selection of a letter E, in the third last consequent step the letters accumulator module facilitates only a letter B, which transliterates in the predicted word zebra, after completion of only three steps.

[0063] Reference is now made to FIG. 11, which shows a method for integrated reduced keyboard disambiguation and touch-based precise character selection, comprising the swipe method of selection, the method comprising, for a number of repetitions, steps of: enabling entry of an at least one letter by a succession of swiping from a key or tapping a key; If enabling entry of an at least one letter by swiping from a key the letter is selected according to the direction from key center to the letter 102; if direction is ambiguous, selecting two letters 104; allocating to each letter probability according to deviation from letter's direction 106; if direction is unambiguous, selecting one letter 108; adding to accumulated letters/pairs/groups of letters and calculating predicted words 110; prioritizing probable words that end with recently added letter/s 112; and presenting predicted words according to the priorities 114. If enabling entry of an at least one letter is by tapping a key 116; selecting all letters included in the tapped key 118; adding to accumulated letters/pairs/groups of letters and calculating predicted words 110; prioritizing probable words that end with recently added letter/s 112; and presenting predicted words according to the priorities 114.

[0064] Reference is now made to FIG. 12, which shows a method for integrated reduced keyboard disambiguation and touch-based precise character selection, comprising the long and short tap methods of selection, the method comprising, for a number of repetitions, steps of: enabling entry of an at least one letter by a succession of taps; If a long tap of a key 202 and/or an alternative distinct way to a long tap of key selection; presenting all letters included in the tapped key 204; selecting the presented letter by a succession of tap 206; adding to accumulated letters/groups of letters and calculating predicted words 208; prioritizing probable words that end with recently added letter/s 210; and presenting predicted words according to the priorities 212. If shortly tapping a key 214; selecting all letters included in the tapped key 216; adding to accumulated letters/groups of letters and calculating predicted words 208; prioritizing probable words that end with recently added letter/s 210; and presenting predicted words according to the priorities 212.
