Definitions
- the present invention relates to text entry systems.
- Tegic T9 TM
- disambiguation software is used such that a only a single press per desired letter is required.
- a menu key is provided. Pressing the key causes a menu including a symbols entry and a numbers entry to appear. The user cursors to the desired entry using dedicated cursor keys, then presses the menu key again to select. For numbers, the user presses the corresponding number key(s). For symbols, a "map" is displayed giving a correspondence between a set of symbols and the number keys.
- some devices incorporate a miniature QUERTY-like keyboard having keys that are comparatively tiny. If the layout is QUERTY-based, one having some keyboarding skill may locate a desired letter relatively quickly. Effectiveness is increased where the keys of different halves of the keyboard are operated by opposite ones of the user's thumbs, as in the Blackberry (TM) device from Research in Motion (RIM). Even so, manipulation of the tiny keys remains
- a text entry system is desired that does not require a stylus or the manipulation of tiny keys.
- a text entry system is also desired that is more versatile and more easily remembered from use to use than existing telephone keypad systems, such that an increasing skill level may be built up.
- the present invention provides a text entry system that uses a relatively small number of keys and that is well-adapted to memorization and skill-building.
- the text entry system is based on a set of well-chosen, "morphologically significant" symbols, related in pairs, with one such symbol assigned per key.
- a letter is entered unambiguously by sequentially pressing one or multiple keys, preferably exactly two keys.
- the number of symbols in the set is fewer than the number of keys in a telephone keypad.
- "Extra" keys are assigned to other characters or actions, such as "space,” “period,” backspace,” and return.

- Figure 27 is a diagram illustrating lookup operation
- the "keys" may be electro- mechanical or may be purely electrical ⁇ i.e., touch keys.
- the indicia appearing on the keys may be fixed or variable (variable, for example, in the case of touch keys overlying a display).
- the invention principally contemplates activation of the keys by direct touch, activation may also be performed using a stylus.
- the keys will be identified by the numbers 0-11, the * key being designated as key 10 and the # key being designated as key 11.
- each letter of the English alphabet is assigned a unique symbol or combination of symbols.
- each letter is assigned a two-symbol combination.
- the following combinations are exemplary:
- the symbols / and ⁇ may also be provided.
- Figure 3 shows another embodiment of the keypad using these symbols.
- italic letters may be used to represent the various symbols, as follows: ⁇ (left angle) is represented by /, > (right angle) is represented by r, ⁇ (up angle) is represented by u, v (down angle) is represented by d, _ (horizontal line) is represented by h,
- alternative combinations using s and b may be as follows:
- the symbols described may be provided on the keys in various different ways, such as printing, embossing, display, etc.
- One type of keypad uses clear plastic keys having printing on the back side of the keys.
- the symbols may be provided as clear ridges or embossings on the surface of the keys, allowing the printing on the back side of the keys to remain clearly visible.
- the present text entry system may be provided in addition to other existing text entry systems that rely on markings provided on the keys (or in addition to stylus- based text entry systems). Embossings provide the further advantage of tactile feedback.
- numerics, punctuation, cursoring, etc. may be provided for in many different ways.
- One way, of course, is to simply provide additional keys. Assuming that no additional keys are to be provided, there are still many ways of providing the foregoing features.
- Capitalization may be provided by designating key 11 as a shift key.
- capitalization may be designated by keeping the initial key depressed for a perceptibly longer time than usual, or by enter two spaces prior to the desired capital letter (as in T9).
- Cap lock and cap unlock may be provided in toggle fashion by pressing shift twice.
- cap lock and unlock may be provided in toggle fashion by simultaneously pressing, for example, the "period" key while inputting the first or last of a series of capital letters.
- Modes may be switched automatically in context-dependent fashion based on device operation. Where manual mode-switching is required, it may be performed, e.g., by pressing the 0 key (numeric mode), shift 10 (cursor mode) or shift 8 (punctuation mode). Alternatively, mode-switching may be performed by, e.g., pressing key 1 for a perceptibly longer duration than normal. In numeric mode, the keys may operate like those of a conventional telephone keypad.
- Punctuation may be provided in many different ways. Where manual mode-switching is required, it may be performed as described previously or by, e.g., pressing the "period" key for a perceptibly longer duration than normal. Normally, punctuation mode persists for the entry of one punctuation mark, after which text mode automatically resumes.
- punctuation marks may be entered, for example, either "morphologically" or by initial letter. The morphological approach is described later.
- punctuation mode would first be designated, after which the letter Q would be entered. Where multiple punctuation marks have the same initial letter, the most frequently occurring one is used by default. If this is not correct, the next most frequency punctuation mark beginning with that letter may be substituted by pressing " ⁇ ," and so forth, until the correct punctuation mark is displayed. (Here it is assumed that a punctuation mark will not normally be followed with one of the letters having " ⁇ " as the initial symbol.)
- Cursoring may be performed using the keys bearing the " ⁇ ", “V”, “ ⁇ ”, and “>” symbols. Cursor mode may be entered (or exited) as described above, or by pressing one of the foregoing keys for a perceptibly longer period of time than normal.
- cursor mode continues until the user presses a "non- cursor" key — one that's not ⁇ , > , ⁇ , or v. So, to cursor to a spot and then enter a letter that begins with one of these symbols, it is necessary to backspace first to exit cursor mode, re-enter the deleted character if needed, then enter the desired letter.
- any of various pointing devices may be integrated with the keypad, for example the "pointing stick" popularized by IBM or a miniature track- marble.
- a pointing device may be integrated with or in the vicinity of the "space” key, for example.
- the space key may be made to operate in similar fashion as a pointing stick.
- a small boundary space is provided around the space key (for example, by making the space key slightly smaller than other keys), and the space key is provided with a "sticky" tactile surface (which also causes the space key to serve as a tactile reference point).
- the key (“pointing key") is adapted to be moved by the finger in any desired direction, allowing for pointing to be performed in similar manner as a pointing stick.
- the basic form of the key remains unchanged and distinct from that of the pointing stick.
- one or more keys may be made touch-sensitive, allowing for touch-pad-like operation.
- the present input method becomes well-adapted for mobile web browsing.
- punctuation marks may be entered by entering the initial letter of a desired punctuation mark.
- many web page links will have text associated with them and may be selected by entering the initial letter of the desired link. If multiple links have the same initial letter, these links may be highlighted as a signal to the user to input the next letter in the desired link.
- link text may be made conditional on the type of device to which the web page is to be sent such that, if the web page is to be sent to a mobile device, link text may be made visible that might otherwise remain hidden were the web page to be sent to a desktop or laptop machine, for example. This design measure will enhance the usefulness of this manner of mobile device web browsing.
- the browser is modified to, when a page is received, form a link text table.
- a link text table When character input is received, if a received character corresponds to a unique link text table entry, the link is followed. If the character corresponds to multiple link text table entries, the link text for these entries is highlighted, prompting the user to make a further entry.
- Figure 4 illustrates a generic hardware arrangement with which the present input system may be used.
- a keypad or keypads like that previously described is coupled to a suitable controller. Based on user inputs, the controller forms an output stream that is sent to a device. The device displays information on one or more displays. The output stream may identical to that of a standard keyboard. The behavior of the controller is such as to realize the functions previously described.
- the keys 7-11 may be assigned the following functions:
- the punctuations marks found on keys 7-12 include the following: ?, period, comma, *, @ and #.
- a period is entered simply by pressing key 9.
- the punctuations marks ?, @ and comma are entered by first pressing the Shift key, then pressing the key corresponding to the desired punctuation mark.
- the punctuation marks * and # are entered by first pressing the Num key (since they are in the position of the number on the numbered keys), then pressing the key corresponding to the desired punctuation mark.
- are entered by first pressing the Shift key, followed by the Punc key, then pressing the key corresponding to the desired punctuation mark.
- An otherwise unused key combination (e.g., >, ⁇ ) may also be used to designate a command mode as described later.
- a help graphic like that of Figure 2 may be displayed during use of a device, for example at the bottom of the display. (The user may be able to display or hide the help graphic as desired.)
- a dot is attached to the first symbol of the combination to make clear to the user which symbol is entered first.
- Figure 5 shows an alternative help graphic.
- the graphic shows the letters of the alphabet as formed by the symbols ⁇ , v, ⁇ , >, - and
- D and F are shown as reversed images (or in color, if available) since, in the embodiment described, their constituent symbols are entered in the reverse order as compared to the expected order, i.e., >,
- Various other devices may be used to distinguish symbols or letters, for example color, shading, line weight, etc.
- a sixth key may be a dedicated space key.
- the functions of other keys e.g., backspace, period and return
- Period and return may be entered using multiple spaces. In this alternative embodiment, entering two spaces followed by a letter capitalizes that letter. Entering three spaces followed by a letter causes a period and a return to be entered after the previous letter, and capitalizes the following letter. Period and return may also be entered from a list of common punctuation marks as described later.
- Backspace may be entered by pressing the space key and, before releasing the space key, pressing any other key, once for a single backspace or multiple times for multiple backspaces.
- a full complement of keyboard functions may be realized using a keypad having only six keys.
- backspace was entered by pressing the space key and, before releasing the space key, pressing any other key.
- This technique of using multiple key presses at a time is common with computer keyboards and may also be used together with the present Simile input method to speed text entry by entering common punctuation marks, common words, and common letter combinations.
- the uppercase letter may be the first entry in the punctuation list.
- the common words in this list are those most common in everyday use.
- Two other word lists may also kept, one (MyWords) for words that may be common to the user but not the population at large, another (DocWords) for words not on the other word lists but used repeatedly in the current document.
- MyWords for words that may be common to the user but not the population at large
- DocWords for words not on the other word lists but used repeatedly in the current document.
- To access these lists enter the beginning letter of the word and hold down the second key of the key combination. Then press another other key, to the right or to the left. Now reverse the roles of the two keys.
- the two lists MyWords and DocWords are displayed side-by-side. Select an entry the same way as with the common word list.
- the picture sequences of Figure 12 and Figure 13 illustrate this technique.
- a letter may be designated while signalling additional follow-on input in any of at least four different ways. Take for example the letter C (input as d, l). This letter may be designated while signalling additional follow-on input in any of the following ways:
- Each of the foregoing possibilities may trigger a different device response, e.g., word input, letter combination input, punctuation input, command input or menu name input, etc.
- a lookup operation is performed as follows.
- the user enters one or more letters (e.g., C) and then signals lookup by a particular user input designated for this purpose. In the illustrated embodiment, this is signalled using an otherwise unused key combination (r, ).
- a list is displayed of words that begin with the inputted letter. For simplicity, this single list may consolidate together words from all of the lists previous described (common words, MyWords, DocWords). In this illustrated embodiment, the list is displayed as multiple columns, here two.
- a key on the right-hand side of the keypad is used to iterate down the right-hand column, and a key on the left-hand side of the keypad is used to iterate down the left-hand column.
- the key not used to iterate is used to perform selection, hence the left-hand key for the right-hand column and the right-hand key for the left-hand column.
- the desired word may not be found on the list, in which case pressing backspace dismisses the list.
- one or more further letters may be entered, causing there to be displayed a new list of words having the expanded stem.
- Numbers may be entered by first pressing and holding any key, then pressing the desired number key. To enter multiple numbers in succession, hold down the first key until the last number has been entered (or, if needed, release that key and press and hold down a different key.) In some configurations having a reduced number of keys, two (or more) numbers may be assigned to the same key. In this instance, a number may be entered by pressing that key once or multiple times as in the well-known one-tap, two-tap, three-tap system sometimes used for text input. The picture sequences of Figure 19 and Figure 20 illustrate this technique.
- the keys marked ⁇ , v, >, and ⁇ may be used as cursor keys. Press for a prolonged period a desired cursor key. Cursor mode is then entered, as indicated by a blinking cursor. Each successive press of a cursor key cursors advances the cursor one row or space in the corresponding direction. Pressing a cursor key again for a prolonged period exits cursor mode. To select text, press and hold a non-cursor key while cursoring. The picture sequences of Figure 21 and Figure 22 illustrate these techniques.
- a trackwheel and escape key as in the RIM Blackberry device may be provided.
- a pointing function may be provided using four keys, for example the lower-most, right-most two keys and lower-most, left-most two keys (or a different set of four keys designated by color or some other device).
- Pointing is achieved by repeatedly dividing the screen into four parts (recursive quadrisection) and pressing the key corresponding to the part containing the desired point on the screen. To begin pointing, press and hold for a prolonged period the one of the four keys that corresponds to the desired quadrisection. (If as between graphical selection and cursoring the desired operation is not clear from context, press in addition any other key.) A faint grid is displayed dividing the display area into quadrisections, indicating that pointing mode has begun.
- Recursive quadrisection may be used for coarse graphical selection or cursor positioning, and a pointing stick or pointing key may be used for fine selection or positioning.
- Commands may be entered by pressing a key sequence to enter a command mode, then pressing the key combination for the first letter of the name of the command.
- command mode may be entered by pressing either the / key or the ⁇ key, then pressing the same key again and holding it down. Command options are then displayed. While still holding down the previous key, any other key may be pressed to advance through the list of commands.
- the commands may be individual commands or command menus and may be accessed individually or by grouping. For example, the Save command could be accessed under the letter S as well as under the letter F representing a File menu.
- Space key may be used to access common punctuations marks, so also the Space key may be used to access command menus (regardless of the beginning letter).
- a typical device may have as few as four keys used for text input or as may as sixteen and may have an even number or odd number of keys.
- keys need not be positioned all together. Rather, keys operated by different thumbs (e.g., one thumb operating two keys for purposes of inputting letters and the other thumb operating four keys) may be positioned on opposite sides of a display screen, for example, as illustrated in
- a short vertical "space bar” may be provided in the form of two abutting keys provided next to the two keys operated by the one thumb, as illustrated in Figure 6 and Figure 7.
- Simile tones may be used with or without Simile input to convey messages disambiguously via a voice channel.
- a virtual business card, or .vcf file might be transmitted in connection with telephone conversation, by transmitting each character as a pair or tuple of tones.
