## Background
PRIORITY
This application is a divisional of prior pending U.S. patent application Ser. No. 11/141,358, filed on May 31, 2005, which is herein incorporated by reference in its entirety, and priority is claimed to this application. Any disclaimer that may have occurred during the prosecution of the above-referenced application is hereby expressly rescinded, and reconsideration of all relevant art is respectfully requested.


BACKGROUND
A television remote control and some portable electronic devices, such as a cell phone, are difficult to use for text-based searching with current text input methods, particularly due to the limited set of input keys available on such devices. For example, other than the various configuration and television-specific input keys, a television remote control only has a standard numeric input keypad that includes the numbers zero through nine to input a channel selection. A viewer cannot easily input letters for a text search in an electronic program guide to search for a specific program, music, television content, or various other applications that may be available via the viewer's cable provider or other television system content provider. Further, conventional text searching techniques require that a user-entered search term be spelled correctly to locate the desired term.
Other electronic devices, such as a cell phone for example, are typically equipped with a conventional alphanumeric input keypad that includes the numbers zero through nine along with the alphabetic characters “A” to “Z”. Although zero (0) through nine (9) is a total of ten input keys, an alphanumeric or numeric input keypad is commonly referred to as a “9-key” keypad. The letters on a “9-key” keypad are distributed along with the numbers two (2) through nine (9). For example, the number two (2) includes the letters “A”, “B”, and “C”, the number three (3) includes the letters “D”, “E”, and “F”, and so on with each consecutive number being associated with the next consecutive three letters. The letters “Q” and “Z” may not be included on some keypads, but if they are, the number seven (7) has four associated letters to include “Q” and the number nine (9) has four associated letters to include “Z”.
There are techniques available to enter text with an alphanumeric “9-key” keypad, however they are cumbersome and in some cases, can require more user inputs than would actually be required to input a text string for the word itself, such as with a computer keyboard. For example, multi-tapping (also referred to as triple tap) is a technique to enter text and/or letters with a “9-key” keypad, such as with a cell phone to create a text message. As described above, the letters “A”, “B”, and “C” are associated with the number two (2) input key on the keypad. Pressing the input key once enters an “A”, twice enters a “B”, three times enters a “C”, and four times enters a “4”. Spelling out even short words for a text input can require multiple key entries. For example, to spell out “CAB”, a user would have to press the number two (2) input key a total of six times—three more inputs than would even be necessary with a conventional keyboard.
An alternative text-entry technique is “T9” (“text on nine keys”) which selects a letter that is associated with a key input to spell a word correctly based on a likelihood of letter combinations. With “T9”, a user may only have to press an input key once rather than multiple times as with multi-tapping. For example, to again spell out “CAB”, a user would only have to press the number two (2) input key a total of three times (once for “C”, twice for “CC”, and a third time for “CAB”). The “T9” technique is not without its limitations however. Depending on the presumed likely letter combinations, a user may have to switch back to multi-tapping to create a word that “T9” does not recognize, or the user may have to input several “T9” key combinations to create the word.
Irrespective of the technique implemented to enter text with an alphanumeric “9-key” keypad, the conventional text input techniques are cumbersome, often require more key inputs than would otherwise be necessary, and/or require unnatural combinations of key inputs.
SUMMARY
Gesture based character input is described herein.
In an embodiment of gesture based character input, a character shape is input on a keypad device, via selection of a sequence of keys. The character is determined based upon the shape of the character as represented by the selected sequence of keys. Characters derived from multiple key sequences are assembled to create character strings.
In an embodiment each character in a string of characters is represented by a numeric equivalent of the character.

DETAILED DESCRIPTION
Predictive phonetic data search is described in which embodiments provide for improved text searching techniques with a restrictive input device, such as a television remote control, cell phone, or other similar devices that have a conventional “9-key” numeric or alphanumeric input keypad. A user can input a search request to locate a term, such as a particular television program, music channel, network-based application, and the like, where a search “term” can be any form of text, letters, a word, a group of words, and/or any combination of characters and numbers. A numeric index includes a number that matches a numerical equivalent of the term designated in the search request. The numeric index also includes numerical equivalent(s) that correspond to translations of the term and phonetic equivalents of the term so that the term designated in the search request does not have to be spelled correctly when input to locate the search term.
When a numeric equivalent that corresponds to the search term is located in the numeric index, the search term can be obtained from a term index that is mapped to the numeric equivalent(s) which correspond to the search term and/or translations and phonetic equivalents of the search term. The search term can then be returned in response to the search request. For example, the requested search term may be displayed in an electronic program guide on a television that also displays programming information corresponding to the search term, such as for a particular television program. By pre-computing a numeric equivalent for the search term and for the possible translations and/or phonetic equivalents of the search term, the search-and-match process can be executed faster than conventional text-based searching to match the actual characters of a search term.
The terms that are maintained in the term index, and from which the numeric equivalents are determined, are received and identified from any number of text data sources, such as electronic program guide data and/or closed captions data corresponding to television content. The numeric equivalents of each term, the translations of the term, and/or the phonetic equivalents of the term are computed and maintained in the numeric index which can be searched for a requested search term. Each numeric equivalent in the numeric index is mapped to the corresponding search term in the term index such that when a numeric equivalent of the particular search term is located in the numeric index, the corresponding search term in the term index can be returned in response to a search request. This provides that a user need only enter a phonetic equivalent of a term that can be misspelled or does not include all of the letters and/or numbers of the term to minimize the number of keypad inputs, yet still receive a correct response to the search request. Further, the user can enter the search term in one language and receive a response to the search request in another language.
While aspects of the described systems and methods for predictive phonetic data search can be implemented in any number of different computing systems, environments, television-based entertainment systems, and/or configurations, embodiments of predictive phonetic data search are described in the context of the following exemplary system architectures.
FIG. 1 illustrates an exemplary data search system 100 in which embodiments of predictive phonetic data search can be implemented. In this example, the system 100 includes text data sources 102(1-N), a term manager 104, and database server(s) 106. In this example, the text data sources 102(1-1V) include electronic program guide data 102(1), closed captions data 102(2), and/or any text data from various sources 102(N). The text data sources 102(1-N) may also include purchased metadata and/or data that has been edited or translated by hired personnel. In a television-based environment, the system 100 also includes encoding server(s) 108 and a content distribution system 110. The encoding server(s) 108 can be implemented to receive and process the text data received from the text data sources 102(1-N) for distribution to client devices via the content distribution system 106. An exemplary television-based system 900 that includes client devices is described further with reference to FIG. 9.
The term manager 104 can be implemented to receive the text data from the encoding server(s) 108 and/or directly from the various text data sources 102(1-N) themselves. The term manager 104 identifies terms in the text data that may be requested in a search and computes a numeric equivalent of each term. For example, the term manager 104 identifies the term “Seinfeld” from the popular television comedy series in either the electronic program data 102(1) or in the closed captions data 102(2). The term manager 104 then computes a numeric equivalent 112 of the term.
On an alphanumeric keypad, an example of which is shown in FIG. 2, “S” is associated with the seven (7) input key, “E” is associated with the three (3) input key, “I” is associated with the four (4) input key, “N” is associated with the six (6) input key, “F” is associated with the three (3) input key, “E” is associated with the three (3) input key, “L” is associated with the five (5) input key, and “D” is associated with the three (3) input key. As such, the numeric equivalent 112 of the data text term “Seinfeld” is 73463353. It should be noted that the techniques described herein are equally applicable for terms that include capital letters, small letters, and any combination thereof.
The database server(s) 106 include a terms index 114 and a numeric index 116, which in an embodiment, are any form of computer readable media that can store and maintain data. The terms index 114 maintains the terms identified by the term manager 104 in the text data received from the text data sources 102(1-1V). For example, the terms index 114 includes the term “Seinfeld” which a user may search for via an electronic program guide to find and watch an episode of the television program. The numeric index 116 maintains the numeric equivalent(s) 118 of each of the data text terms maintained in the terms index 114. For example, the numeric equivalent 112 (i.e., 73463353) of “Seinfeld” is maintained in the numeric index 116 as the first listed numeric equivalent 120. The numeric equivalent 120 in the numeric index 116 is mapped to the corresponding term “Seinfeld” in the terms index 114 such that when a numeric equivalent of a particular search term is located in the numeric index 116, the corresponding search term in the term index 114 can be returned in response to a search request.
The term manager 104 also computes the additional numeric equivalents 118 that each correspond to a phonetic equivalent 122 of the term. The additional numeric equivalents 118 are also maintained in the numeric index 116 and are mapped to the corresponding term in the terms index 114. The additional numeric equivalents correspond to phonetic equivalents of a particular term in the term index 114 and may be a misspelling of the term, a spelling of the term that includes only consonants and no vowels, and/or a number in place of a word in the term.
For example, the first numeric equivalent 118 that is listed (i.e., 74363353) corresponds to a misspelling of the term “Seinfeld” where a user may input the search term, but misspell the word as “Sienfeld” with an “i” before the “e”. The last numeric equivalent 118 that is listed (i.e., 76353) corresponds to a spelling of the term “Seinfeld” that includes only the consonants of the word “snfld”, and none of the vowels. As such, a user can search for the television show, yet only provide a minimal input with a restrictive input device, such as a television remote control, cell phone, or other similar devices that have a conventional “9-key” numeric or alphanumeric input keypad.
In another example, a user can input search terms where a number is input in place of a word in the search term. For example, a user can search for the television program “Deep Space Nine” by inputting a search for “Deep Space 9”, or as described above “DPSC9” (or by various other letter and number combinations). For another example, a user can search for the television program “Eight is Enough” by inputting a search for “8 is Enough”, or as described above “8ENUF” (or by various other letter and number combinations). It should be noted that the phonetic equivalents 122 shown in FIG. 2 are merely illustrative, and do not need to be maintained or stored in memory, thus saving memory space.
Only the numeric equivalents 118 need be maintained such that the term manager 104 can receive a search input, determine the numerical equivalent of the search input, and then locate the number in the numeric index 116 that corresponds to the numeric equivalent of the search input. For example a user may search for “Star Trek” episodes and enter six (6) keypad inputs for “STRTRK” which the term manager 104 determines to have a numerical equivalent of 787875. Rather than searching for the actual text string of “S,T,R,T,R,K”, the term manager searches the numeric index 116 for “787875”, and when the number is located, obtains “Star Trek” from the terms index 114 to which the number is mapped.
FIG. 2 illustrates an exemplary data search system 200 in which embodiments of predictive phonetic data search can be implemented. The system 200 includes the database server(s) 106 shown in FIG. 1, and in this example, the term manager 104 is shown as a component of a database server 106 to implement the various embodiments of predictive phonetic data search described herein. The system 200 also includes an exemplary television-based client device 202 that receives program content, program guide data, advertising content, closed captions data, and the like for display on a display device 204 (e.g., a television) via a communication network 206, such as the content distribution system 110 shown in FIG. 1. In an embodiment, client device 202 can be implemented with any combination of components described with reference to the exemplary electronic and/or computing device 800 shown in FIG. 8. Further, an exemplary television-based system 900 is described further with reference to FIG. 9.
A user can input a search request to locate a term, such as a particular television program, music channel, network-based application, and the like with a restrictive input device, such as a television remote control 208, a cellular phone 210, or a PDA 212 that only has a “9-Key” alphanumeric keypad 214. A search term can be any form of text, letters, a word, a group of words, and/or any combination of characters and numbers. For example, the user may input a search request in an electronic program guide displayed on the display device 204 via the client device 202 with the television remote control 208. Alternatively, (although not shown) a user may input a search request to the client device 202 via the cellular phone 210 and/or the PDA 212 which may be configured to operate as a television remote control device.
A user may also input a search request with the cellular phone 210 and/or the PDA 212 via a wired or wireless connection 216 that is received by the term manager 104. The user can input the search request with the “9-Key” alphanumeric keypad 214 on the cellular phone 210 or PDA 212 and have the requested term returned for display on a display component of the cellular phone 210 or PDA 212. For example, a user may want to search for an upcoming broadcast of a “Seinfeld” episode, and then have the associated programming information displayed via the cellular phone 210 or PDA 212 so that the user will know what time to be home to watch the television program. Although the examples described herein pertain to searching for the “title” of a program, such as “Seinfeld”, a requested search can include any terms that may be associated with a program, movie, gaming application, music, and the like. For example, a user may search for a particular actor, director, singer, or any other criteria or category of data that can be searched to locate a requested term.
A user can enter a search term via a numeric or alphanumeric keypad, such as the “9-Key” alphanumeric keypad 214, on the television remote control 208, cellular phone 210, or PDA 212 as any one of: a sequence of characters, a sequence of letters each associated with a channel number input key on the keypad of the television remote control 208, as a sequence of letters each associated with a telephone number input key entered on a keypad of the cellular phone 210, as a text-based input that includes a sequence of characters that correspond to two or more words, as a combination of alphabetic character(s) and numeric character(s), as a phonetic equivalent of the term, as the phonetic equivalent which is a misspelling of the term, as the phonetic equivalent which includes only consonants in the term and no vowels, as the phonetic equivalent that includes a number in place of a word in the term, and/or any combination thereof. This list of search term inputs is not intended to be all-inclusive, but to merely illustrate some of the possible inputs that may be used to minimize the number of keypad entries needed when searching text data with a restrictive input device.
As described, a requested search term can be returned for display via an electronic program guide displayed on display device 204 (e.g., a television), or the requested search term can be displayed on a display component of the cellular phone 210 or PDA 212. Additionally, a requested search term may return multiple listings or results which can all be displayed for the requesting user. For example, a search for a program listing or television program may return several instances of upcoming scheduled broadcasts of the program. Although an on-demand movie or gaming application does not have a typical broadcast schedule, the information returned for display may include when the on-demand content will become available to order, the associated cost, and/or any other similar information. The information returned for display in response to a requested search term may also be annotated based on a popularity of the results, to identify which of the returned search terms are already designated to be recorded (for a television program, for example), and/or any other annotations associated with the information returned for display.
In another embodiment of predictive phonetic data search, a user can enter a search term in one language with the “9-Key” alphanumeric keypad 214 on the cellular phone 210 or PDA 212 and have the requested term returned for display in another language. For example, a user may want to determine if the movie “Tres Amigos”, which is titled in Spanish, is available for viewing. The user may then enter a search request in English as any one of “3 Friends”, “3friends”, or “3FRNDS” (just for examples) to locate programming information associated with the movie. Optionally, a user may configure a preference such that a response to a request entered in any language is returned in a specified language, such as Spanish. For example, if an English-speaking user is traveling in Mexico, the user can enter a search term in English on the “9-Key” alphanumeric keypad 214 on the cellular phone 210 or PDA 212 and have the requested term displayed in Spanish on a display component of the cellular phone 210 or PDA 212.
FIG. 3 illustrates exemplary database components 300 that can be implemented as part of the data search systems shown in FIGS. 1 and 2, and which can be implemented in embodiments of predictive phonetic data search. The database components 300 include the terms index 114 and the numeric index 116 described with reference to FIG. 1. The database components 300 also include a term instance index 302 and a translations index 304.
In this example, the terms index 114 includes the illustrative terms “seinfeld”, “terminator”, and “garden” which may be requested in a search by a user. As described above with reference to FIG. 1, a term in the terms index 114 corresponds to numeric equivalents in the numeric index 116. For example, numeric equivalents 306 include the numeric equivalent 73463353 that corresponds to the keypad inputs for the term “seinfeld”, and includes numeric equivalents of various phonetic equivalents 308 of the term “seinfeld”. The numeric equivalents 306 in the numeric index 116 are mapped to the term “seinfeld” in the terms index 114.
Similarly, the numeric equivalents 310 include the numeric equivalent 8376462867 that corresponds to the keypad inputs for the term “terminator”, and includes numeric equivalents of various phonetic equivalents 312 of the term “terminator”. The numeric equivalents 310 in the numeric index 116 are mapped to the term “terminator” in the terms index 114. Similarly, the numeric equivalents 314 include the numeric equivalent 427336 that corresponds to the keypad inputs for the term “garden”, and includes numeric equivalents of various phonetic equivalents 316 of the term “garden”. The numeric equivalents 314 in the numeric index 116 are mapped to the term “garden” in the terms index 114. It should be noted that the phonetic equivalents 308, 312, and 316 shown in FIG. 3 are merely illustrative to show the derivation of the respective numeric equivalents 306, 310, and 314.
The translations index 304 includes translations of the term “garden” which are mapped to the term “garden” in the terms index 114. When a user requests a translation of the term “garden” and a numeric equivalent 314 of the search term is located in the numeric index 116, a translation of the search term can be returned in response to the search request. For example, a user in China may enter a search request for “GRDN” on the keypad of a cellular phone or PDA (or other portable electronic device) which is a phonetic equivalent 316 that is determined to have a numerical equivalent 314 of 4736. The numerical equivalent 314 in the numeric index 116 can be mapped back to the term “garden” in the terms index 114, and the term “garden” can be mapped to the Chinese translation aM of the term in the translations index 304. Although translations are only shown for the term “garden” in the translations index 304 in this example, each of the terms in the terms index 114 may have translations included in the translations index 304.
The term instance index 302 includes service identifiers (i.e., a “Service_Id”) that each correspond to a term in the terms index 114. A service identifier includes term instances that define how content associated with a term is presented for use by a user if a user selects the term from displayed results. For example, the term “terminator” in the terms index 114 can be returned in response to a user initiated search request and displayed as options for user selection. In this example, the options may correspond to a broadcast of the movie “Terminator”, on-demand availability of the movie, a trailer of the movie, a video game based on the movie, or a soundtrack of the movie.
The term instances 318 corresponding to the “terminator” term indicate that if the user selects to view the trailer of the movie, then the trailer will be received at the user's client device for viewing. Similarly, if the user selects to watch a broadcast of the movie, or orders the movie from an on-demand service, the user's client device will be tuned to receive the broadcast or on-demand presentation of the movie. Alternatively, if the viewer selects the video game option, the video game can also be rendered from an on-demand service and/or an offer to purchase the video game can be displayed for the user. If the user selects the soundtrack option, then the music corresponding to the movie can be streamed to the user's client device such that the user can listen to the soundtrack.
FIG. 4 illustrates an example of a search request that is input as a shape-based search request 400 using a “9-Key” alphanumeric keypad 402 to implement a predictive phonetic data search. In this example, a user inputs a request for a search term “LOUD” and inputs each letter of the term with shape-based pattern movements over the keypad such that the keypad is being utilized as a touch pad. For example, to enter the “L” input of the term at 404, a user can form an L-shape with keypad entries in a sequence of the one (1) key, four (4) key, seven (7) key, eight (8) key, and nine (9) key.
Similarly, to enter the “0” input of the term at 406, a user can form an 0-shape with keypad entries in a sequence of the one (1) key, four (4) key, seven (7) key, eight (8) key, nine (9) key, six (6) key, three (3) key, two (2) key, and one (1) key. To enter the “U” input of the term at 408, a user can form a U-shape with keypad entries in a sequence of the one (1) key, four (4) key, seven (7) key, eight (8) key, nine (9) key, six (6) key, and three (3) key. To enter the “D” input of the term at 410, a user can form a D-shape with keypad entries in a sequence of the one (1) key, four (4) key, seven (7) key, eight (8) key, six (6) key, two (2) key, and one (1) key.
The term manager 104 (as described with reference to FIG. 1) can be implemented to receive the key entry sequences that each correspond to a letter of the requested search term, and determine each of the letters. The term manager 104 can then determine the numerical equivalent of the search input to be 5683 (i.e., the single key inputs for the term “LOUD”), and then locate the number in the numeric index 116 that corresponds to the numeric equivalent of the search term input.
Methods for predictive phonetic data search, such as exemplary methods 500-700 described with reference to respective FIGS. 5, 6, and 7, may be described in the general context of computer executable instructions. Generally, computer executable instructions can include routines, programs, objects, components, data structures, procedures, modules, functions, and the like that perform particular functions or implement particular abstract data types. The methods may also be practiced in a distributed computing environment where functions are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, computer executable instructions may be located in both local and remote computer storage media, including memory storage devices.
FIG. 5 illustrates an exemplary method 500 for predictive phonetic data search, and is described with reference to generating search terms and numeric equivalents. The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof.
At block 502, text data is received from one or more text data sources. For example, text data can be received from text data source(s) 102(1-1V) (FIG. 1) which can include electronic program guide data 102(1), closed captions data that corresponds to television content 102(2), and/or any other text data source 102(M. At block 504, search terms are identified in the text data. For example, the term manager 104 can identify terms in the received text data that may be requested by a user in a search
At block 506, a numeric equivalent of each search term is computed. For example, the term manager 104 computes a numeric equivalent 112 of the requested search term. At block 508, additional numeric equivalents each corresponding to a phonetic equivalent of a search term are computed. For example, the term manager also computes additional numeric equivalents 118 that each correspond to a phonetic equivalent 122 of the requested search term. A phonetic equivalent of a search term can be a misspelling of the search term, a spelling of the search term that includes only consonants and no vowels, and/or a number in place of a word in the search term. The additional numeric equivalents are computed for any one or more of the phonetic equivalents.
At block 510, the numeric equivalent(s) associated with each search term are maintained in a numeric index. For example, the numeric equivalent(s) 118 are maintained in the numeric index 116 and include the numeric equivalent 120 corresponding to the correct spelling of the search term as well as the additional numeric equivalents 118 that each correspond to a phonetic equivalent 122 of the search term. The numeric equivalent(s) 118 can be searched in response to a search request for a particular search term.
At block 512, each numeric equivalent in the numeric index is mapped to the corresponding search term in a term index. For example, the numeric equivalents 118 corresponding to the requested search term in the numeric index 116 are mapped to the terms maintained in the terms index 114 such that when a numeric equivalent of a requested search term is located in the numeric index 116, the corresponding search term in the term index 114 can be returned in response to a search request.
At block 514, one or more translations of a search term are generated and, at block 516, the one or more translations of the search term are maintained in a translations index For example, the term manager 104 can generate translations of a term that are maintained in the translations index 304 (FIG. 3). At block 518, the one or more translations in the translations index are mapped to the corresponding search term in the term index. For example, the translations for the term “garden” in the translations index 304 are mapped to the term “garden” in the terms index 114 such that when the numeric equivalent of a requested search term is located in the numeric index, a translation of the search term can be returned in response to the search request.
FIG. 6 illustrates an exemplary method 600 for predictive phonetic data search, and is described with reference to a search request for a particular search term. The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof.
At block 602, a search request is received to locate a term. For example, the term manager 104 (FIG. 2) can receive a search request from a user for a particular term. A search request can be received as inputs to a restrictive input device, such as a television remote control 208, a cellular phone 210, or a PDA 212 that only has a “9-Key” alphanumeric keypad 214. A search request can be received as any one of: a sequence of characters, a sequence of letters each associated with a channel number input key on the keypad of the television remote control 208, as a sequence of letters each associated with a telephone number input key entered on a keypad of the cellular phone 210, as a text-based input that includes a sequence of characters that correspond to two or more words, as a combination of alphabetic character(s) and numeric character(s), as a phonetic equivalent of the term, as the phonetic equivalent which is a misspelling of the term, as the phonetic equivalent which includes only consonants in the term and no vowels, as the phonetic equivalent that includes a number in place of a word in the term, and/or any combination thereof.
At block 604, a numeric index is searched to locate a number that matches a numerical equivalent of the term. For example, the term manager 104 can search the numeric index 116 to locate a numeric equivalent 118 (FIG. 1) of a requested search term. At block 606, the term is obtained from a term index that is mapped to the number in the numeric index which matches the numerical equivalent of the term. For example, the numeric equivalent 118 of the search term is mapped to the term in the terms index 114.
At block 608, the search request is processed to return the term based on a designated response instance of the term. For example, the term manager 104 can return the requested term based on a designated term response instance 318 (FIG. 3) that corresponds to the ‘term in the terms index 114. At block 610, the term is returned in response to the search request. For example, the requested term can be returned for display and according to the designated term response instance, as a translation of the term, as a list of likely terms that correspond to the term in response to the search request, or as any one of a program schedule, a broadcast television selection, an on-demand selection, or an application program.
FIG. 7 illustrates an exemplary method 700 for predictive phonetic data search, and is described with reference to a search request initiated as a shape-based input on a keypad. The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof.
At block 702, a sequence of characters are received as a search request to locate a term, the sequence of characters each being entered as shape-based inputs that approximate a character. For example, a user can input a request for a search term by inputting each letter of the requested search term with shape-based pattern movements over a keypad 402 (FIG. 4) such that the keypad is being utilized as a touch pad. At block 704, the shape-based inputs that approximate a character are converted into at least one of an alphabetic or numeric character for each of the characters in the sequence. For example, the term manager 104 can receive the key entry sequences that each correspond to the letters “L,O,U,D” of the requested search term in the example 400, and determine each of the letters.
At block 706, a numerical equivalent of the term is computed as determined from the sequence of characters. At block 708, a numeric index is searched to locate a number that matches a numerical equivalent of the term. For example, the term manager 104 can then determine the numerical equivalent of the search input to be 5683 (i.e., the single key inputs for the term “LOUD” in FIG. 4), and then locate the number in the numeric index 116 that corresponds to the numeric equivalent of the search input. At block 710, the term is obtained from a term index that is mapped to the number in the numeric index which matches the numerical equivalent of the term. At block 712, the term is returned in response to the search request.
