FIGURE 2 is a block diagram depicting a shorthand-aided rapid keyboarding enabled touchscreen 205 operating in accordance with an example embodiment of the invention. In an example embodiment, an electronic device 200 comprises a user interface, such as shorthand-aided rapid keyboarding enabled touchscreen 205. The shorthand-aided rapid keyboarding enabled touchscreen 205 comprises a text input 210, one or more keys 215, a word path 220, a start position 225, and a stop position 230.

In an embodiment, the shorthand-aided rapid keyboarding touchscreen 205 is configured to receive user input from at least one of the following: tablet, handheld PCs, computer, touchscreen, electronic device, and/or the like. In an example embodiment, shorthand-aided rapid keyboarding may be referred to as Shapewriter®. Using shorthand-aided rapid keyboarding text entry software, a user draws words on a graphical keyboard using a pen. In an embodiment, the user interface is configured to receive a user trace, such as a pen gesture, a finger motion, a stylus, and/or the like that is drawn connecting one or more letters in a desired word. The term "shorthand-aided rapid keyboarding touchscreen" is used in this application to refer to a touchscreen that is suitable for use with the entry of a trace between locations that are associated with particular characters. This screen may be a conventional touchscreen, and might be configured to present a virtual keyboard and accept a trace drawn between keys of that virtual keyboard. However, the invention may be implemented using other hardware and software. For example, any touch- sensitive surface may be used in place of a touchscreen, so long as it permits the user to draw a trace between locations that are associated with characters.

In one embodiment, such a touch-sensitive surface may be provided by a physical keypad (i.e. one comprising discrete physical keys) wherein each key is configured to detect the presence of a finger, stylus, or other object touching and/or proximate the key. This might be achieved using capacitance sensing, or any other suitable technology. The physical keys may further be pressable, and thus capable of conventional press-actuation in addition to touch sensing. hi other embodiments, technologies other than touch sensing may be used to enter at least the trace component of the user input. For example, an apparatus may be provided with an optical sensor that detects a trace drawn by the user either on a surface (e.g. a piece of paper), or in the air.

It will be understood that whilst the invention will be described according to specific hardware embodiments (e.g. a touchscreen), it is intended that it may instead be implementable using any of the above-described technologies - or by other suitable technologies that are not described. hi an example embodiment, shorthand-aided rapid keyboarding uses handwriting recognition, hi an embodiment, handwriting recognition is the ability of . a processor, such as processor 20 of FIGURE 1, to receive and interpret intelligible handwritten input from sources such as paper documents, photographs, touch-screens and other devices. The image of the written text may be sensed "off line" from a piece of paper by optical scanning, such as optical character recognition, intelligent word recognition, and/or the like. In an alternative embodiment, user movements of the pen tip may be sensed "on line", for example by a pen-based computer screen surface.

In an example embodiment, a shorthand-aided rapid keyboarding enabled touchscreen 205 is configured to receive a user input. In an example embodiment, the user input is a swiping movement. For example, a user swipes along a word path 220 to spell the word "store." This word path 220 can be referred to as a "trace". In an embodiment, the user input is at least one of the following: press, long press, hard press, combination thereof, and/or the like. For example, a user presses the "S" on the shorthand-aided rapid keyboarding enabled touchscreen 205. In another example, the user traces between the "STORE" keys but changes the force he applies when, tracing over the "E" key on the shorthand-aided rapid keyboarding enabled touchscreen 205. In such an example, the change in force represents the end of the word "STORE".

In an example embodiment, a processor, such as processor 20 of FIGURE 1, for the electronic device 200 is configured to identify a position in a text input 210 based at least in part on the user input. For example, the processor identifies when the user input begins, e.g., letter "S", as a start position 225. Further, the processor identifies where the user input ends, e.g., pressing letter "E", as a stop position 230.

In the above example, only one word was entered - "STORE". However, because the start and end points of this word are known, the trace can be extended to include further words, in which case the trace entered by the user may comprise more than one word path 220. For example, suppose that the trace passes through the characters "STOREBOX"; because the user has increased the pressure he is applying on the touchscreen whilst he traces through the "E" key, the overall trace can be broken apart into two separate word traces - "STORE" and "BOX", and recognized as such.

Shorthand-aided rapid keyboarding is an example of ambiguous text input, because it is not always clear which keys the user intends to trace through and which are purely incidental. For example, whilst tracing the word "STORE" on an English QWERTY keyboard it is likely that the path will actually pass through the following keys: "SDRTYUIOIUYTRE". Of these, only "S", "T'\ "0", "R", and "E" are intended to form part of the text entry, the others simply lie on the path between these keys. Analysis of the locations at which the trace changes direction (for example at the "O" key), and comparison with the words in a dictionary and/or statistical information (e.g. n-gram data) can be used to determine likely word candidates from the ambiguous input, but this becomes significantly more complex when a single trace comprises more than one word shape. For this reason, the ability to demarcate wordshapes by identifying their stop and start locations within a larger trace simplifies the disambiguating process. In the above example, a change in pressure on the touchscreen was used as a demarcating input to separate the component wordshapes of a trace. However, other inputs could alternatively be used. For example, the trace could be temporarily held at the location of the last character of each word, or a completely separate button on the device could be pressed at the moment the trace passed over these last characters.

It will be apparent from the above that the use of a demarcation input allows the trace to be continued between words without sacrificing efficiency or accuracy in the disambiguation process. What is more, the continuous nature of the trace between words can be used to simplify the process of text entry, and improve the speed of shorthand-aided rapid keyboarding, which would otherwise require the trace to be broken and restarted for each new word.

In an example embodiment, the processor determines a non alphanumeric character based at least in part on the user input at the stop position 230. For example, in the "STORE" example above the press on the "E" key represents a stop position and the system will recognize this as the end of a word. A space character may therefore be automatically appended to the word in response to the stop position.

In another embodiment the non-alphabetic character may be dependent upon a user input, for example a space may be entered at a stop position by default, but if the user employs a special demarcation input (a long press in place of a short press, for example) then the space may be replaced by e.g. a period, question mark, exclamation point, comma, other symbol, or a combination thereof.

In another embodiment, a non-alphanumeric character is appended after the end of the trace. For example, it may be assumed that the end of a trace represents the end of a sentence and that a terminal punctuation mark such as a period is required. In further embodiments, the user may indicate that he requires a particular terminal punctuation mark (e.g. by making a long keypress, or other special input) and will be presented with an option such as a menu from which he can select a particular terminal punctuation mark.

For example, a user presses the "e" key at the stop position 230. In an embodiment, the key press represents punctuation. For example, the key press represents a period, a question mark, an exclamation point, a symbol, or a combination thereof. In such a case, the shorthand-aided rapid keyboarding enabled touchscreen 205 is configured to display the non alphanumeric character in the text input 210, e.g., add a period. A technical effect of one or more of the example embodiments disclosed herein is adding a non alphanumeric character based at least in part on a user input.

In some embodiments, the start position 225 and stop position 230 may be used to for word prediction. For example, the processor compares the letters of the path traversed and compares it to the options available in an internal dictionary as known in the art. In an embodiment, the internal dictionary may comprise user added words. In an embodiment, a second internal dictionary may exist with user added words. Further, internal dictionaries may be downloadable thereby allowing updates. Further still, internal dictionaries may provide a predictive language technique to calculate the next most probable matches of the word. In an alternative embodiment, the internal dictionaries may employ statistical analysis, e.g. which letters most probably follow a certain letter in English or other language to determine the word. In an example embodiment, the processor is configured to detect the first and last characters of a user press. The processor may match the user presses with the internal dictionary. For example, the processor may return a number of potential matches, such as store, stout, stir, sore, dure, and/or the like, based on the user input. Based at least in part on these potential matches, the processor may add the knowledge of which character was the first and last character, and hereby re-order or filter the list of matches so that the words starting with S and ending with E are listed first, e.g., for the word store.

Consider the following example. A user touches the start position 225 for a word, e.g., "S" for the word Store. The user may then traverse a path 220 including at least certain intermediate letters of the word, and then presses the stop position 230 of the word, e.g., the letter "E". For example, a user enters the word "store" on path 220 by first pressing the letter "S," traversing the finger toward the letter "T," then the "O" and "R" before coming to rest on the letter "E" where the user presses the E key. In such a case, the shorthand-aided rapid keyboarding enabled touchscreen 205 displays the word "store" in the text input 210. FIGURE 3 is a block diagram depicting another shorthand-aided rapid keyboarding enabled touchscreen 205 operating in accordance with an example embodiment of the invention. In an example embodiment, an electronic device 200 comprises a user interface, such as shorthand-aided rapid keyboarding enabled touchscreen 205. The shorthand-aided rapid keyboarding enabled touchscreen 205 comprises a text input 210, one or more keys 215, and a word path 220.

In an example embodiment, the shorthand-aided rapid keyboarding enabled touchscreen 205 is configured to receive a user input. In an example embodiment, the user input is at least one of the following: press, long press, hard press, combination thereof, and/or the like. For example, the shorthand-aided rapid keyboarding enabled touchscreen 205 detects a press.

In an example embodiment, the processor determines a non alphanumeric character based at least in part on the user input, e.g., the press. For example, a user presses the "e" key. In an embodiment, the key press represents punctuation. For example, a period, a question mark, an exclamation point, a symbol, or a combination thereof. In such a case, the shorthand-aided rapid keyboarding enabled touchscreen 205 is configured to display the non alphanumeric character in the text input 210, e.g., add a period. In an example embodiment, the shorthand-aided rapid keyboarding enabled touchscreen 205 detects a hard press.

In an embodiment, a hard press is related to force. In an example embodiment, the force may define a start or end of a word. In example above for the word "STORE" a user presses the screen harder when starts the swipe from "S" and reduces the force of pressure. The user presses the screen harder again when entering next word thereby indicating the end of the word "STORE." In an alternative embodiment, the user presses with more force during of the word. For example, the user can swipes characters STOR normally and then press harder the screen when swiping over character E. In an example embodiment, the user swipes words with same force of pressure, but changes the force, e.g., harder, lighter pressure, and/or the like, when moving from last character of a word to a first character to a next word thereby adding a space between words. In an alternative embodiment, the user may employ a touch- click. In an embodiment, a touch display has a mechanical moving display and a 'dome' underneath the touch display. The touch display is configured to allow distinguishing between 'soft-swiping' and pressing hard.

In an example embodiment, the processor determines a non alphanumeric character based at least in part on the user input, e.g., the hard press. For example, a user performs a hard press on the "e" key. In an embodiment, the hard press represents word completion. In an embodiment, the processor compares the letters of the path traversed and compares it to the options available in an internal dictionary as known in the art. In such a case, the shorthand-aided rapid keyboarding enabled touchscreen 205 is configured to display the completed word.

In an embodiment, the shorthand-aided rapid keyboarding enabled touchscreen 205 compries a capacitive sensor, a sense matrix, and/or the like disposed beneath the one or more keys 215. Further, the shorthand-aided rapid keyboarding enabled touchscreen 205 may contain an array of discrete key switches, as is known in the art, in addition to the capacitive sense matrix, or the sense matrix may be fashioned to be responsive to key activation force or changes in capacitance related to intentional key activation by a user. Thus, the shorthand-aided rapid keyboarding enabled touchscreen 205 may be configured to determine finger location and whether or not a key has been pressed. In an embodiment, a processor, such as processor 20 of FIGURE 1, is configured to determine a key press, such as a non alphanumeric character or alphanumeric character, using signal intensity. The keys of the keypad may have independently movable, spaced-apart key caps, or the keys may comprise discrete regions of a single keypad surface, such as a flexible membrane. In an example embodiment, the keypad is a QWERTY keyboard configuration. In an alternative embodiment, the keypad is an International

Telecommunication Union (ITU)-T keypad. In an embodiment, the ITU-T keypad is the traditional mobile device keypad comprising 12 basic keys, that is, number key 0- 9, *-key and #-key. ITU-T is a standard of International Telecommunication Union. Other configurations are also possible. The keypad described above may be implemented as a virtual keypad on a touchscreen. However, it may instead be implemented as a physical hardware keypad that is configured to detect touch input.

In an embodiment, the shorthand-aided rapid keyboarding enabled touchscreen 205 may be configured to determine signal intensity as based at least in part on a user's finger elevation above the surface of the shorthand- aided rapid keyboarding enabled touchscreen 205 with respect to time. In an embodiment, the shorthand-aided rapid keyboarding enabled touchscreen 205 may be calibrated to the user's finger size as a key is pressed, thereby providing a measurement of signal strength to finger distance. In an embodiment, signal intensity increases as the user presses the "S, T, O, R" keys, remains relatively constant during a standard "traverse" and then increases again as the user presses the "E."

FIGURE 4 is a block diagram depicting yet another shorthand-aided rapid keyboarding 205 enabled touchscreen operating in accordance with an example embodiment of the invention. In an example embodiment, an electronic device 200 comprises a user interface, such as shorthand-aided rapid keyboarding enabled touchscreen 205. The shorthand-aided rapid keyboarding enabled touchscreen 205 comprises a text input 210, one or more keys 215, and a word path 220. In an example embodiment, an electronic device 200 comprises a user interface, such as shorthand-aided rapid keyboarding enabled touchscreen 205. The shorthand-aided rapid keyboarding enabled touchscreen 205 comprises a text input 210, one or more keys 215, and a word path 220. In an example embodiment, the shorthand-aided rapid keyboarding enabled touchscreen 205 is configured to receive a user input. In an example embodiment, the user input is at least one of the following: press, long press, hard press, combination thereof, and/or the like. In an alternative embodiment, the shorthand-aided rapid keyboarding enabled touchscreen 205 is configured to detect a finger press or touch. Further, the shorthand-aided rapid keyboarding enabled touchscreen 205 may be further configured to detect the area of the finger press or touch. In such a case, the shorthand-aided rapid keyboarding enabled touchscreen 205 detects the key based at least in part on the area of the finger press or touch.

In an example embodiment, the shorthand-aided rapid keyboarding enabled touchscreen 205 is configured to receive a user input. In an example embodiment, the user input is at least one of the following: press, long press, hard press, combination thereof, and/or the like. For example, the shorthand-aided rapid keyboarding enabled touchscreen 205 detects a long press.

In an example embodiment, the user interface displays one or more special characters, such as a symbol, trademark designation, and/or the like. For example, a user presses the "e" key and the user interface displays a special character menu 440.

In an embodiment, the user may select a special character 450. In an embodiment, the shorthand-aided rapid keyboarding enabled touchscreen 205 is configured to display the special character 450 in the text input 210. In an embodiment, the non alphanumeric character is displayed while a user continuously touches the shorthand- aided rapid keyboarding enabled touchscreen. In an alternative embodiment, the special character menu 440 is displayed if a user motion passes over a shape associated with the special character menu 440. In another alternative embodiment, the special character 450 may be selected if a user moves over a special character 450 located on the user interface, e.g., on the keyboard and not a separate menu.

In an example embodiment, the shorthand-aided rapid keyboarding enabled touchscreen 205 is configured to receive a user input. In an example embodiment, the user input is a swipe over one or more numbers on, for example, an ITU-T keypad. For example, the user swipes over five numbers for a zip code. In an alternative embodiment, the ITU-T keypad may be used for inputting words. For example, a user selects a letter mode on the ITU-T keypad and swipes numbers in letter mode. In an embodiment, the swiped numbers may be matched in an internal dictionary, such as a predictive text entry works, e.g., 7-8-6-7-3 represents the word "store." It should be understood that embodiments of the invention may employ a QWERTY keypad, an

ITU-T keypad, other keypads, and/or the like.

FIGURE 6 is a flow diagram depicting an example method 600 for display a non alphanumeric character in accordance with an example embodiment of the invention. Example method 600 may be performed by an electronic device, such as electronic device 100 of FIGURE 1.

At 605, a user input is received. In an example embodiment, a keypad, such as shorthand-aided rapid keyboarding 200 of FIGURE 2, is configured to receive a user input. In an example embodiment, the user input is a swiping movement. For example, a user swipes along a word path, such as word path 220 of FIGURE 2, to spell the word "store." In an embodiment, the user input is at least one of the following: press, long press, hard press, combination thereof, and/or the like. For example, a user presses the "S" on the keypad.

At 610, a position in a text input based at least in part on the user input is identified. In an example embodiment, the processor is configured to identify a position in a text input, such as text input 210 of FIGURE 2, based at least in part on the user input. For example, the processor identifies when the user input begins, e.g., letter "S", as a start position. Further, the processor identifies where the user input ends, e.g., pressing letter "E", as a stop position for the word "STORE." At 615, a first character is marked based at least in part on the user input. In an example embodiment, the processor is configured to mark the first character based at least in part on the user input. For example, the processor marks the letter "S" as the first character for the word "store."

At 620, a last character is marked based at least in part on the user input. In an example embodiment, the processor marks the last character based at least in part on the user input. For example, the processor is configured to mark the letter "E" as the last character for the word "store."

At 622, accuracy of the word is determined. In an embodiment, the processor is configured to determine accuracy of the word based at least in part on the first word character and the last word character. For example, the processor uses an internal dictionary to verify the accuracy of the user inputted word.

At 625, a non alphanumeric character is determined based at least in part on the user input. In an example embodiment, the processor determines a non alphanumeric character based at least in part on the user input. For example, a user presses the "e" key. In an embodiment, the key press represents punctuation. For example, the key press represents a period, a question mark, an exclamation point, a symbol, or a combination thereof. At 630, the non alphanumeric character is displayed. In an example embodiment, the shorthand-aided rapid keyboarding enabled touchscreen is configured to display the non alphanumeric character, e.g., a period.

Without in any way limiting the scope, interpretation, or application of the claims appearing below, a technical effect of one or more of the example embodiments disclosed herein may be improved accuracy using a shorthand-aided rapid keyboarding enabled touchscreen. Another technical effect of one or more of the example embodiments disclosed herein may be adding a non alphanumeric character based at least in part on a user input.
