## Title
Techniques for input of a multi-character compound consonant or vowel and transliteration to another language using a touch computing device

## Abstract

A technique is presented for fast input of multi-character compound consonants and vowels on a touch computing device. The technique provides for fast input of multi-character compound consonants and vowels by enabling a user to touch an initial character on a first layout of characters, then slide his/her finger in different directions and/or different distances according to a second layout of characters. The second layout of characters can be based on the first touched character and therefore can have a limited set of characters, e.g., fewer characters in comparison to the first layout of characters. A syllable formed after input of both a consonant and a vowel, represented as one character set, e.g., in the Roman alphabet, can then be transliterated into another language, e.g., Chinese.

Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
“Touch computing devices” include computing devices that receive tactile input from a user. For example, touch computing devices may include mobile phones, tablet computers, portable media players, electronic readers, and the like. Typically, the user may input information to a touch computing device via a touchpad or touch screen (hereinafter referred to as a “touch display”). For example, the touch display may be a capacitive sensing display. The touch display may both display information to the user and receive input from the user. The user may typically input information to the touch computing device by typing using a provided layout of characters. For example, the provided layout of characters may be a form of a standard QWERTY keyboard.
SUMMARY
A computer-implemented technique is presented. The technique includes providing, via a touch display of a touch computing device, a first layout of English characters. The technique also includes receiving, via the touch display of the touch computing device, spot input from a user of the touch computing device, the spot input indicating selection of a vowel from the first layout of English characters. The technique also includes providing, via the touch display of the touch computing device, a second layout of English characters based on the spot input, the second layout of English characters being centered about the selected vowel and including a plurality of characters based on and including the selected vowel, the second layout of English characters being different than the first layout of English characters. The technique also includes receiving, via the touch display of the touch computing device, slide input from the user from the selected vowel to a selected character of the second layout of English characters. The technique also includes determining, at the touch computing device, a string of English characters based on the selected vowel, the selected character, and the second layout of English characters, the string of English characters selectively including one or more other English characters of the second layout of English characters along a path of the slide input, the string of English characters representing a vowel of a Chinese character. The technique also includes generating, at the touch computing device, a Chinese character based on the string of characters. The technique further includes displaying, via the touch display of the touch computing device, the Chinese character.
Another computer-implemented technique is also presented. The technique includes providing, via a touch display of a touch computing device, a first layout of characters in a first language. The technique also includes receiving, via the touch display of the touch computing device, spot input from a user, the spot input indicating a selection of a first character from the first layout of characters. The technique also includes providing, via the touch display of the touch computing device, a second layout of characters in the first language, the second layout of characters being based on the selected first character, the second layout of characters being different than the first layout of characters. The technique also includes receiving, via the touch display of the touch computing device, slide input from the user from the selected first character to a selected second character from the second layout of characters. The technique also includes determining, at the touch computing device, a string of characters based on the selected first and second characters and the second layout of characters, the string of characters representing a syllable in a second language, the second language being different than the first language. The technique further includes displaying, via the touch display of the touch computing device, the string of characters.

DETAILED DESCRIPTION
Referring now to FIG. 1A, an example of a touch computing device 100 is shown. The touch computing device 100 may be a mobile phone, a tablet computer, or the like. The touch computing device 100 generally includes a touch display 104. The touch display 104 can displays information and/or receive input from a user 108. For example only, the touch display 104 may be a capacitive sensing display. As shown, the user 108 may typically input information to the touch computing device 100 via the touch display 104 using one or more fingers 112. The user 108 may also use other objects such as a stylus, a pen, or the like.
Input techniques to the touch computing device 100 include “spot input” and “slide input.” FIG. 1B illustrates spot input to the touch computing device 100. Spot input generally includes selection of a single spot 116 on the touch display 104 by the user 108. For example, as shown in FIG. 1B, the user 108 may perform spot input to select the character “g” on a displayed keyboard. FIG. 1C illustrates slide input to the touch computing device 100. Slide input generally includes a sliding motion 120 across the touch display 104 by the user 108. For example, the user 108 may perform slide input to move an object currently being displayed by the touch display 104, such as an image, a webpage, or the like.
As previously described, touch computing devices are widely available and thus may be used in many different countries throughout the world. Therefore, touch computing devices may be configured to display information to and/or receive information from the user 108 in a variety of different languages. Input method editors, or IMEs, are software applications that allow a user to input different languages to a touch computing device. Many languages are based on the Latin alphabet, e.g., English, Spanish, and French. There are many other languages, however, that are based on other characters or symbols. These languages may be characterized as syllabogram-based and logogram-based languages.
One widely used logogram-based language is Chinese. Chinese script includes thousands of unique characters. Pinyin is the official English alphabet-based transliteration of Chinese. Transliteration refers to the process of converting one script to another, e.g., English to Chinese. In other words, Pinyin refers to a system for English alphabet-based phonetic representations of Chinese characters. For example only, “zai jian” is the Pinyin representation of “” or “”, which means “goodbye” and “under construction” in English, respectively. Therefore, one IME for touch computing devices may be a Pinyin-based IME for providing input of Chinese characters for text messaging, e-mailing, and the like.
The pronunciation of most Chinese characters can be expressed in two parts: a consonant and a vowel. The consonants for Chinese include 20 consonants of the English alphabet (except for “v”) plus three additional multi-character compound consonants: ch, sh, and zh (23 total). A list of the various Chinese (Pinyin) consonants is provided below:

    
    
        b, c, ch, d, f, g, h, j, k, l, m, n, p, q, r, s, sh, t w, x, y, z, and zh.

The vowels for Chinese include, in addition to the five vowels of the English alphabet, “ü” (which is input as “v”) and 27 other multi-character compound vowels (33 total), e.g., ang, en, uang. Tables of the various Chinese (Pinyin) vowels are shown below:

The possible combinations of consonants and vowels for Chinese are greater than 400. As can be appreciated, having to input individual English alphabet-based characters to input each Chinese character, e.g., the multi-character compound vowel “uang”, can be time consuming. For example only, one of the longest Pinyin representations is “shuang”, which includes the consonant “sh” followed by the multi-character compound vowel “uang” and thus requires six different English alphabet-based characters. In sum, traditional Pinyin-based IMEs may require more user time and effort than desired.
Accordingly, techniques are presented for slide input of a multi-character compound consonant or vowel for transliteration to another language. While the techniques described in detail herein are generally directed to English (Pinyin) input and transliteration to Chinese, the techniques may also be applied to other languages such as, for example only, Japanese or Korean. The techniques presented provide for faster and easier input of multi-character compound consonants and vowels to a touch computing device. Using the techniques presented for English (Pinyin) input and transliteration to Chinese, most Chinese multi-character compound consonants and vowels may be input using two spot inputs (“clicks”) or less, e.g., a consonant plus a vowel, notwithstanding the potential slide input after one or both of the various clicks.
Referring now to FIG. 2, a functional block diagram of the touch computing device 100 is illustrated. As previously described, the touch computing device 100 includes the touch display 104, such as a capacitive sensing display. The touch display 104 displays information to the user 108 and/or receives information input by the user 108. The touch computing device 100, however, can further include a user interface module 200, a transliteration module 204, a language datastore 208, and a communication module 212. It should be appreciated that the touch computing device 100 may include additional computing components such as memory and the like.
The user interface module 200 controls communication with the user 108 via the touch display 104 of the touch computing device 100. The user interface module 200 may provide the user 108 with various different character input configurations via the touch display 104 of the touch computing device 100. For example, the user interface module 200 may provide the user 108 with a form of the standard QWERTY keyboard via the touch display 104 of the touch computing device 100. Alternatively, for example, the user interface module 200 may provide the user 108 with a standard 12-key configuration, also known as a telephone layout configuration. The user interface module 200 may also receive input from the user 108, e.g., via the provided character input configuration.
The transliteration module 204 receives the input from the user 108 as interpreted by the user interface module 200. The user interface module 200 and the transliteration module 204 can collectively execute various IMEs, e.g., an English (Pinyin) to Chinese IME, thereby enabling the user 108 to input characters in different languages. The transliteration module 204, therefore, may also convert the input received from the user 108 to a desired language, e.g., Chinese. For example, the transliteration module 204 may use the language datastore 208 when transliterating the user input to the desired language (described in detail later). The transliteration module 204 can communicate with the user interface module 200 in order for the user interface module 200 to provide the various character input configurations to the user.
The communication module 208 controls communication between the touch computing device 100 and other devices. For example only, the communication module 208 may provide for communication between the touch computing device 100 and other users associated with the user 108 via the Internet. The touch computing device 100 may communicate via: a computing network 250, a mobile telephone network 254, and/or a satellite network 258. Other communication mediums may also be implemented. For example, the communication module 208 may configured for both wired and wireless network connections, e.g., radio frequency (RF) communication.
As previously mentioned, the user interface module 200 can provide various character input configurations (“character layouts”) to the user 108 via the touch display 104 of the touch computing device 100. For example, the character layouts may include a standard QWERTY keyboard, a standard 12-key telephone layout configuration, and the like. The user interface module 200 may also provide alternative character layouts according to the present disclosure for purposes of inputting multi-character compound consonants and vowels (described and shown in more detail later). For example, the user interface module 200 may first provide the user 108 with a standard QWERTY keyboard having English characters and, after a spot input by the user of a selected character, the user interface module 200 may provide a second configuration of English characters corresponding to possible multi-character compound consonants and vowels beginning with the selected character.
The user interface module 200 can also determine a desired input by the user 108. More specifically, the user interface module 200 can determine a string of characters input by the user 108 based on both spot input by the user 108 and slide input by the user 108. The spot input by the user 108 indicates a first selected character from a first character layout provided to the user 108. The slide input by the user 108 is from the first selected character to a second selected character from a second character layout provided to the user 108. In addition, depending on the character layout provided to the user 108 and a path of the slide input by the user 108, the string of characters may further include characters of the second character layout along the path of the slide input between the first and second selected characters.
As previously mentioned, the transliteration module 204 communicates with the language datastore 208 in order to convert the input received via the user interface module 200. Conversion from the string of English characters (Pinyin) to a Chinese character (or a list of Chinese characters) may also be referred to as transliteration. The transliteration module 204 may convert the input from the user 108, e.g., the string of characters, to a desired language. For example, the desired language may be set by the user 108 and/or may be a parameter of an IME that is currently being used. As previously described, the string of characters may represent a transliteration of a desired language, e.g., English characters (Pinyin) and Chinese being the desired language. The transliteration module 204 may use data stored in the language datastore 208 to perform the transliteration. After transliteration is complete, the transliteration module 204 may then provide the one or more transliterated characters, e.g., Chinese characters, to the user interface module 200. The user interface module 200 can then display the one or more transliterated characters to the user 108 via the touch display 104 of the touch computing device 100.
The language datastore 208 stores data corresponding to various different languages such as, for example only, English, Chinese, Spanish, French, Japanese, and Korean. The stored data may include lexicons for the various languages, rules for the various languages, rules for converting between the various languages, and the like. For example, the language datastore 208 may be memory, e.g., non-volatile memory, located within the touch computing device 100. Additionally or alternatively, all or part of the language datastore 208 may be located remotely, e.g., in the cloud, and thus may be accessed via the communication module 212. In addition, the communication module 212 may provide for periodic updating of all or part of the stored data that is stored locally, e.g., in the language datastore 208.
Referring now to FIGS. 3A-3E, examples of various character layouts for slide input of a multi-character compound vowel for transliteration to a Chinese character are shown. Each of these character layouts may be displayed to and interacted with by the user 108 via the touch display 104 of the touch computing device 100. While specific character layouts are shown for inputting each simple or multi-character compound vowel via a spot input or a spot input followed by a slide input, other character layouts may be used. For example, the character layouts may be optimized based on statistics of vowel appearances throughout the Chinese/Pinyin lexicon. In other words, slide input paths corresponding to the most frequently used vowels may be the shortest paths. Additionally or alternatively, for example, the configurations may be optimized based on statistics of users 108, e.g., optimized for right-handed or left-handed users.
Referring now to FIG. 3A, an example character layout 300 for slide input of vowels beginning with the English alphabet letter a is shown. As previously described, the possible vowels beginning with the letter a in Chinese include the simple vowel a in addition to the multi-character compound vowels ai, an, ang, and ao. The user 108 may input the simple vowel a via a spot input at the letter a. The letters i, n, and o are located above, to the right of, and below the letter a, respectively. The user 108 may input the multi-character compound vowels ai, an, or ao via a spot input at the letter a followed by a slide input up, right, or down, respectively. The letter g is located to the right of the letter n because of the multi-character compound vowel ang (but the lack of a multi-character compound vowel “ag”). The user 108 may input the multi-character compound vowel ang via a spot input at the letter a followed by a slide input to the right, the slide input being longer or further than the right slide input for the letter n.
Referring now to FIG. 3B, an example character layout 320 for slide input of vowels beginning with the English alphabet letter e is shown. As previously described, the possible vowels beginning with the letter e in Chinese include the simple vowel e in addition to the multi-character compound vowels ei, en, eng, and er. The user 108 may input the simple vowel e via a spot input at the letter e. The letters i, n, and r are located to the left of, to the right of, and below the letter e, respectively. The user 108 may input the multi-character compound vowels ei, en, or er via a spot input at the letter e followed by a slide input left, right, or down, respectively. The letter g is located to the right of the letter n because of the multi-character compound vowel eng (but the lack of a multi-character compound vowel “eg”). The user 108 may input the multi-character compound vowel eng via a spot input at the letter e followed by a slide input to the right, the slide input being longer or further than the right slide input for the letter n.
Referring now to FIG. 3C, an example character layout 340 for slide input of vowels beginning with the English alphabet letter i is shown. As previously described, the possible vowels beginning with the letter i in Chinese include the simple vowel i in addition to the multi-character compound vowels ia, ian, iang, iao, ie, in, ing, iong, and iu. The user 108 may input the simple vowel i via a spot input at the letter i. The letters a, u, and a first letter n are located to the left of, below, and to the right of the letter i, respectively. The user 108 may input the multi-character compound vowels ia, iu, or in via a spot input at the letter i followed by a slide input left, down, or right, respectively.
A second letter n is located left of the letter a. A letter o is located below the letter a. The user 108 may input the multi-character compound vowels ian or iao via a spot input at the letter i followed by a slide input left (longer or further than the left slide input for the letter a) or a slide input left and then down, respectively. For example only, the multi-character compound vowel iao (and/or the multi-character compound vowel long, described in detail below) could be input by sliding from the letter i diagonally down and to the left. A first letter g is located left of the second letter n. The user 108 may input the multi-character compound vowel iang via spot input at the letter i followed by a slide input left, the slide input being longer or further than the left slide input for the second letter n.
A second letter g is located right of the first letter n. Letters ong are located below the first letter n. The user 108 may input the multi-character compound vowels ing or iong via a spot input at the letter i followed by a slide input right (longer or further than the right slide input for the first letter n) or a slide input diagonally down and to the right, respectively. For example only, the letters ong may be located at this diagonal location because the multi-character compound vowel long is used less frequently than the other vowels beginning with the letter i. Additionally or alternatively, for example only, the letters ong may be located at this diagonal direction to keep a consistent layout amount ang, eng, and ing.
Lastly, the letter e is located below the letter u. The user 108 may input the multi-character compound vowel ie via a spot input at the letter i followed by a slide input down, the slide input being longer or further than the down slide motion for the letter u. For example, the slide input path of the user 108 may curve around the letter u. In some cases, the letter u, located along the slide input path, could be discarded because the multi-character compound vowel “iue” does not exist. For example only, the letter e may be located far away from the letter i because the multi-character compound vowel ie is used less frequently than the other vowels beginning with the letter i. Additionally or alternatively, for example only, another layout could position the letter e directly above the letter i.
Referring now to FIG. 3D, an example character layout 360 for slide input of vowels beginning with the English alphabet letter o is shown. As previously described, the possible vowels beginning with the letter o in Chinese include the simple vowel o in addition to the multi-character compound vowels ou and ong. The user 108 may input the simple vowel o via a spot input at the letter o. The letters u and ng are located to the left of and below the letter o, respectively. The user 108 may input the multi-character compound vowels ou or ong via a spot input at the letter o followed by a slide input left or down, respectively.
Referring now to FIG. 3E, an example character layout 380 for slide input of vowels beginning with the English alphabet letter u is shown. As previously described, the possible vowels beginning with the letter u include the simple vowel u in addition to the multi-character compound vowels ua, uai, uan, uang, ue, ui, un, and uo. The user 108 may input the simple vowel u via a spot input at the letter u. The letters a, o, and a first letter n are located to the left of, below, and to the right of the letter u, respectively. The user 108 may input the multi-character compound vowels ua, uo, or un via a spot input at the letter i followed by a slide input left, down, or right, respectively.
A second letter n is located left of the letter a. The user 108 may input the multi-character compound vowel uan via a spot input at the letter u followed by a slide input left, the slide input being longer or further than the left slide input for the letter a. A letter e/i is located below the letter a. The user 108 may input the multi-character compound vowels ue or ui via a spot input at the letter u followed by a slide input diagonally left and down. The letters e and i share the same location because there are no overlapping pronunciations of ui and ue, e.g., jue, lue, nue, que, xue, yue; chui, cui, dui, gui, hui, kui, rui, shui, sui, ui, zhui, zui.
The letter g is located left of the second letter n. The user 108 may input the multi-character compound vowel uang via spot input at the letter u followed by a slide input left, the slide input being longer or further than the left slide input for the second letter n. Lastly, the letter i is located below the letter second letter n. The user 108 may input the multi-character compound vowel uai via a spot input at the letter u followed by a slide input left, and then diagonally down and to the left. In addition, the second letter n, located along the slide input path, may be discarded because the multi-character compound vowel “uani” does not exist. Alternatively, the user 108 may input the multi-character compound vowel uai via a spot input at the letter u followed by a slide input diagonally down and to the left, the slide input being further than the diagonally down and left input for the letter e/i. For example only, the letter i may be located far away from the letter u because the multi-character compound vowel uai is used less frequently than the other vowels beginning with the letter u.
Referring now to FIGS. 3F-3H, example character layouts 385, 390, and 395 for slide input of consonants beginning with the English alphabet letters c, s, and z are shown, respectively.
Referring now to FIG. 3F, the example character layout 385 for slide input of consonants beginning with the English alphabet letter c is shown. As previously described, the possible consonants beginning with the letter c include the simple consonant c in addition to the multi-character compound consonant ch. The user 108 may input the simple consonant c via a spot input at the letter c. The letter h is located to the right of the letter c. The user 108 may input the multi-character compound consonant ch via a spot input at the letter c followed by a slide input right.
Referring now to FIG. 3G, the example character layout 390 for slide input of consonants beginning with the English alphabet letter s is shown. As previously described, the possible consonants beginning with the letter s include the simple consonant s in addition to the multi-character compound consonant sh. The user 108 may input the simple consonant s via a spot input at the letter s. The letter h is located to the right of the letter s. The user 108 may input the multi-character compound consonant sh via a spot input at the letter s followed by a slide input right.
Referring now to FIG. 3H, the example character layout 395 for slide input of consonants beginning with the English alphabet letter z is shown. As previously described, the possible consonants beginning with the letter z include the simple consonant z in addition to the multi-character compound consonant zh. The user 108 may input the simple consonant c via a spot input at the letter z. The letter h is located to the right of the letter z. The user 108 may input the multi-character compound consonant zh via a spot input at the letter z followed by a slide input right.
Referring now to FIG. 4, an example character layout 400 for slide input of multi-character compound consonants and vowels via a 12-key telephone layout configuration is shown. This character layout 400 may be displayed to and interacted with by the user 108 via the touch display 104 of the touch computing device 100. While the specific character layouts for vowels (shown in FIGS. 3A-3E and described above) may be implemented for the character layout 400, some of those configurations may need to be changed, e.g., the user 108 cannot slide from key 4 (vowel i) to the left in order to input multi-character compound vowel iang. Therefore, some or all of the specific character layouts may be reconfigured for this character layout 400, which may include optimization based on lexicon statistics and/or user statistics as previously described.
Referring now to FIG. 5, another example of a technique 500 for slide input of multi-character compound vowels of a Chinese syllable using the touch computing device 100 begins at 504. At 504, the user interface module 200 provides, via the touch display 104 of the touch computing device 100, a first layout of English characters. At 508, the user interface module 200 receives, receiving, via the touch display 104 of the touch computing device 100, spot input from the user 108 of the touch computing device 100, the spot input indicating selection of a vowel from the first layout of English characters.
At 512, the user interface module 200 provides, via the touch display 104 of the touch computing device 100, a second layout of English characters based on the spot input, the second layout of English characters being centered about the selected vowel and including a plurality of characters based on and including the selected vowel, the second layout of English characters being different than the first layout of English characters. At 516, the user interface module 200 receives, via the touch display 104 of the touch computing device 100, slide input from the user 108 from the selected vowel to a selected character of the second layout of English characters.
At 520, the user interface module 200 determines, at the touch computing device 100, a string of English characters based on the selected vowel, the selected character, and the second layout of English characters, the string of English characters selectively including one or more other English characters of the second layout of English characters associated along a path of the slide input, the string of characters representing a vowel of a Chinese character. At 524, the transliteration module 204 generates, at the touch computing device 100, a Chinese character based on the string of characters. At 528, the user interface module 200 displays, via the touch display 104 of the touch computing device 100, the Chinese character. The technique 500 may then end or return to 504 for one or more additional cycles.
Referring now to FIG. 6, an example technique 600 for slide input of a multi-character compound consonant or vowel for transliteration to another language using the touch computing device 100 begins at 604. At 604, the user interface module 200 provides, via the touch display 104 of the touch computing device 100, a first layout of characters in a first language. At 608, the user interface module 200 receives, via the touch display 104 of the touch computing device 100, spot input from the user 108, the spot input indicating a selection of a first character from the first layout of characters. At 612, the user interface module 200 determines, at the touch computing device 100, whether the selected character is an initial character of a multi-character compound consonant or vowel, e.g., a, c, e, i, o, s, u, or z. If true, the technique 600 can proceed to 616. If false, the technique 600 can proceed to 628.
At 616, the user interface module 200 provides, via the touch display 104 of the touch computing device 100, a second layout of characters in the first language, the second layout of characters being based on the selected first character, the second layout of characters being different than the first layout of characters. At 620, the user interface module 200 receives, via the touch display 104 of the touch computing device 100, slide input from the user 108 from the selected first character to a selected second character from the second layout of characters. At 624, the user interface module 200 determines, at the touch computing device 100, a string of characters based on the first and second selected characters and the second layout of characters, the string of characters representing a syllable in a second language. At 628, the user interface module 200 displays, via the touch display 104 of the touch computing device 100, the selected character or the string of characters (depending on the decision at 612). The technique 600 may then end or return to 604 for one or more additional cycles.
