Abstract

Certain aspects of the present methods and systems may focus on computer implemented methods of obtaining digitized hand-writing data corresponding to a sample of a needed code point of a set of code points. Such methods may include: obtaining a sample of digitized handwritten text, the sample of digitized handwritten text including glyph data corresponding to a first glyph, the first glyph corresponding to the needed code point of the set of code points; associating the first glyph with the needed code point; identifying stroke data in the glyph data, the stroke data corresponding to a stroke component of the first glyph, determining a plurality of dimensional values of the stroke component in the stroke data; and associating the plurality of dimensional values with a new code point sample of the needed code point in a code point set data structure.

Description

FIELD

The present disclosure relates to computer handwriting analysis and synthesis, and more particularly, to systems and methods for digitized handwriting data collection and analysis.

BACKGROUND

Since the advent of desktop publishing in the mid-1980s, it has become increasingly easy to use commonly-available software to create and print letters, cards, documents, and other printed matter. Moreover, at the present time, a computer user may have scores or even hundreds of high-quality fonts installed on his or her computer, with thousands of additional free and commercial fonts available via the Internet. As a result, many people have become accustomed to receiving printed materials that are not hand-written. Indeed, hand-written notes and cards may signal to a recipient a sense of importance and particular care because the sender personally took the effort to hand-craft the message.
There are numerous fonts that are intended to mimic generic handwriting to a certain extent. There are even services that will create a font to mimic a particular person's handwriting. However, existing personalized-handwriting fonts may appear mechanical and/or unnatural because individual glyphs may always be printed with identical geometry, whereas in an actual hand-written document, each individual character may have its own subtly unique geometry. Moreover, existing personalized-handwriting fonts and personalized-handwriting-font-creation services may have difficulty isolating individual glyph within a sample of cursive handwriting or other handwriting in which adjacent letters may be connected to one another.
Other techniques may use a variable glyph representation to mimic an individual's handwriting, such as the systems and methods described in U.S. Pat. Nos. 8,351,700 and 8,699,794.

Furthermore, these processes and operations may utilize conventional computer components in a heterogeneous distributed computing environment, including remote file servers, computer servers, and/or memory storage devices. Each of these conventional distributed computing components is accessible by the processor via a communication network, which may include, but is not limited to, the Internet.
The phrases “in one embodiment,” “in various embodiments,” “in some embodiments,” and the like are used repeatedly. Such phrases do not necessarily refer to the same embodiment. The terms “comprising,” “having,” and “including” are synonymous, unless the context dictates otherwise.
Reference is now made in detail to the description of the embodiments as illustrated in the drawings. While embodiments are described in connection with the drawings and related descriptions, there is no intent to limit the scope to the embodiments disclosed herein. On the contrary, the intent is to cover all alternatives, modifications, and equivalents. In alternate embodiments, additional devices, or combinations of illustrated devices, may be added to, or combined, without limiting the scope to the embodiments disclosed herein. For example, the embodiments set forth below are primarily described in the context of obtaining data corresponding to digitized samples of handwritten text in the English language via a digitizing surface device and a digitizing marking device. However, these embodiments are exemplary and are in no way limited to the type of item for which recommendations are being generated.

Exemplary Network Topology of a Client/Server-Based Handwriting Ingestion System

FIG. 1 illustrates a first exemplary client/server-based handwriting ingestion system 100 in accordance with various embodiments. Client devices 200A-B and a remote front-end server 300A are in data communication with a network 103. In various embodiments, network 103 may include the Internet, one or more local area networks (“LANs”), one or more wide area networks (“WANs”), cellular data networks, and/or other data networks. Network 103 may, at various points, be a wired and/or wireless network. Remote front-end server 300A may be in data communication with a remote handwriting ingestion server 300B and an administrative data store 105. Remote handwriting ingestion server 300B may be in data communication with a handwriting sample set data store 108.
In these and other embodiments, client devices 200, such as client device 200A and client device 200B, may be networked computing devices having form factors including general purpose computers (including “desktop,” “laptop,” “notebook,” “tablet” computers, or the like); mobile phones; watches, glasses, or other wearable computing devices; or the like. For simplified exemplary purposes, two client devices are shown, one of which is depicted as a laptop computer and the other of which is depicted as a tablet computer. In various embodiments there may be many more client devices 200. The primary functional components of an exemplary, form-factor-independent client device 200 are described below in reference to FIG. 2.
Client device 200A may be in data communication with an external digitizing surface device 218A and a digitizing marking device (e.g. a “stylus”) 220A. Digitizing marking device 220A may be in data communication with client device 200A via external digitizing surface device 218A or may be in direct data communication with the client device (as indicated by dotted lines).
Client device 200B includes a built in digitizing surface device 218B and may be in data communication with a digitizing marking device 220B.
In various embodiments, remote front-end server 300A and remote handwriting ingestion server 300B may be networked computing devices generally capable of accepting requests over network 108, e.g. from client devices 200, each other, various databases, and/or other networked computing devices, such as a remote handwriting generation server (not shown), and providing responses accordingly. The primary functional components of an exemplary remote server 300, such as remote front-end server 300A and remote handwriting ingestion server 300B, are described below in reference to FIG. 3.

Exemplary Client Device

FIG. 2 illustrates several components of an exemplary client device 200, such as any of client devices 200A-B, is illustrated. In some embodiments, a client device 200 may include many more components than those shown in FIG. 2. However, it is not necessary that all of these generally conventional components be shown in order to disclose an illustrative embodiment. The data communications between various components of client device 200 may be accomplished by wired and/or wireless connections
As shown in FIG. 2, exemplary client device 200 includes a central processing unit 203 in data communication with memory 205 via a bus 208. Central processing unit 203 is an electronic circuit designed to carry out instructions of a computer program, e.g. obtained from memory 205, by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the program's instructions. Memory 205 generally comprises some or all of random access memory (RAM), read-only memory (ROM), and/or a permanent mass storage device, such as a disk drive, flash memory, or the like. Bus 208 is a communication system that transfers data between components within client device 200, and encompasses any related hardware components (wire, optical fiber, etc.) and software, including communication protocols.
Client device 200 may also include a network interface 210 for connecting to a network such as network 103, one or more optional user input device(s) 213, e.g. an alphanumeric keyboard, keypad, a mouse or other pointing device, a touchscreen, and/or a microphone, (or a user input port for connecting an external user input device), an optional digitizing surface device 215, such as digitizing surface device 215B, (or a port for connecting an external digitizing surface device, such as digitizing surface device 215A), an optional digitizing marking device (or a port for connecting to an external digitizing marking device, such as digitizing marking devices 218A-B), and the like, all interconnected, along with the network interface 210, to central processing unit 203 and memory 205 via bus 208.
Memory 205 of exemplary client device 200 may store program code, executable by central processing unit 203, corresponding to an operating system 223, as well as program code corresponding to various software applications, such as a browser application 225, a handwriting ingestion application 228, and other software applications (not shown). Operating system 223 and such various software applications may be loaded into memory 205 via network interface 210 or via a computer readable storage medium 230, such as a hard-disk drive, a solid-state drive, an optical disc, a removable memory card, and/or the like.
Browser application 225 is a software application for retrieving, presenting, and traversing information resources on a network, such as network 108. Although browser application 225 may be primarily intended to use the World Wide Web, it may also be used to access information resources provided by remote servers in private networks. An information resource may be a web page, an image, a video, or other piece of content and may be identified by a Uniform Resource Identifier (URI/URL) on network 108. An information resource may also provide browser application 225 executable program code for web applications, i.e. a software application that runs in and is rendered by browser application 225.
In operation, operating system 223 manages the hardware and software resources of client device 200 and provides common services and memory allocation for various software applications, such as research study data acquisition and quality control application 228. For hardware functions such as network communications via network interface 210, receiving data via input 213, outputting data via optional display 215, and allocation of memory 205 for various software applications, such as handwriting ingestion application 228, operating system 223 acts as an intermediary between software executing on the client device and the device's hardware.
For example, operating system 223 may cause a representation of available software applications, such as browser application 225 and handwriting ingestion 228, to be presented to a user of client device 200 via display 215. If client device 200 obtains an indication from a user, e.g. via user input 213, a desire to use handwriting ingestion application 228, operating system 223 may instantiate a handwriting ingestion application process (not shown), i.e. cause central processing unit 203 to begin executing the executable instructions of the handwriting ingestion application and allocate a portion of memory 205 for its use.
In the case of a web application, browser application 225 may act as an intermediary between a software service operating on a remote server and the operating system 223. For example, a software service equivalent of handwriting ingestion application 228 may be executing on front-end server 400A.
Although an exemplary client device 200 has been described with hardware components that generally conforms to conventional general purpose computing devices, a client device may be any of a great number of devices capable of communicating with network 103 and executing instructions for performing handwriting ingestion application 228.

Exemplary Server

FIG. 3 illustrates several components of an exemplary server 300, such as front-end server 300A and handwriting ingestion server 300B, in accordance with at least one exemplary embodiment are illustrated. In some embodiments, a server 300 may include many more components than those shown in FIG. 3. However, it is not necessary that all of these generally conventional components be shown in order to disclose an illustrative embodiment. As shown in FIG. 3, a server 300 includes a central processing unit 303 and memory 305 connected by a bus 308.
Central processing unit 303 is an electronic circuit designed to carry out instructions of a computer program, e.g. obtained from memory 305, by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the program's instructions. Memory 305 may generally include some or all of random access memory (RAM), read-only memory (ROM), and/or a permanent mass storage device, such as a disk drive, flash memory, or the like. Bus 308 is a communication system that transfers data between components within exemplary server 300, and includes any related hardware components (wire, optical fiber, etc.) and software, including communication protocols.
Server 300 may also include a network interface 310 for connecting to a network such as network 103, one or more optional user input device(s) 313, e.g. an alphanumeric keyboard, keypad, a mouse or other pointing device, a touchscreen, and/or a microphone, (or a user input port for connecting an external user input device) and/or an optional display 315 (or a display port for connecting an external display device), both interconnected along with the network interface 310 via bus 308.
Memory 305 may store an operating system 320 and program code for various software services 323. For example, front-end server 300A may include executable instructions for performing user session management service 323A (indicated by dotted lines) and handwriting ingestion server 300B may include executable instructions for performing handwriting ingestion service 323B (indicated by dotted lines).
Program code for these and other such software services, such as a software services (not shown) equivalent to handwriting ingestion application 228, may be loaded into memory 305 from a non-transient computer readable storage medium 325 using a drive mechanism (not shown) associated with the non-transient computer readable storage medium, such as, but not limited to, a DVD/CD-ROM drive, memory card, or the like. Software components may also be loaded into memory 304 via the network interface 310. A server 300 may also communicate via bus 308 with a database (not shown), such as admin database 105 and/or trial data database 108, or other local or remote data store.
In operation, operating system 320 manages the hardware and software resources of server 300 and provides common services and memory allocation for various software services, such as user session management service 323A or handwriting ingestion service 323B. For hardware functions such as network communications via network interface 310 and allocation of memory 305 for various software services, such as handwriting ingestion service 323B, operating system 320 may act as an intermediary between software executing on server 300 and the server's hardware.
Although an exemplary server 300 has been described having hardware components that generally conform to a conventional general purpose computing device, a server may be any of a great number of devices capable of communicating with network 103 and executing instructions for performing user session management service 323A and/or handwriting ingestion service 323B.
In some embodiments, a server 300 may comprise one or more replicated and/or distributed physical or logical devices. In some embodiments, one or more of front-end server 300A and handwriting ingestion server 300B may be embodied by the same physical device.

Client/Server-Based Handwriting Ingestion Systems

Referring collectively to FIGS. 1-3, and as is described in more detail below, an instance of client handwriting ingestion application 228 operating on a client device, such as client devices 200A-B, remote user session management service 323A operating on front-end server 300A, and remote handwriting ingestion service 323B operating on handwriting ingestion server 300B (collectively a client/server-based handwriting ingestion system) in accordance with the present embodiments may operate to create a code-point sample data set of a user's handwriting comprehensive enough to allow the provider to obtain text data including a message from a user and generate an image, e.g. for electronic display and/or hard-copy printing, including a sequence of glyphs corresponding the message and having the appearance of being rendered in the user's handwriting. Such a client/server based handwriting ingestion system may be operated in furtherance of a handwriting digitization service provider (not shown) providing handwriting reproduction services.
Instantiations of client handwriting ingestion application 228 may act as an interface between a user of client device 200 and user session management service 323A operating on front-end server 300A. Upon instantiation, client handwriting ingestion application 228 may send a “create new session” request to user session management service 323A, for example including identifying information for client device 200, identifying information for the particular instantiation of client handwriting ingestion application 228, and/or user-account credentials such as a user name and password, obtained from the user or stored in memory 205. If presented, the user-account credentials may be associated with an existing user account or with a generic, temporary, and/or anonymous “guest” account.
User session management service 323A may create a corresponding user session (not shown) associated with the particular instantiation of client handwriting ingestion application 228, identified by a user-session identifier (referred to herein as a “session ID”) and may obtain user account information, such as a user identifier, associated with the provided identifying information from administrative data store 105 and provide a response to client handwriting ingestion application 228, which may include information related to features and services provided by the handwriting digitization service provider which the user-account associated with the user-account credentials are authorized to access.
Client handwriting ingestion application 228 may then present the user with a menu of options, e.g. via optional display 215, and wait for the user to indicate a selection of a specific option, e.g. via optional input 213. Such options may include obtaining a new handwriting sample, viewing a measure of completeness of a handwriting sample set associated with the user identifier, creating a new handwriting sample set, and the like. Upon obtaining a selection of one of the presented options, e.g. via user input 213, client handwriting ingestion application 215 may process the selection and generate a request corresponding to the selected option.
These requests may be provided to user session management service 323A operating on front-end server 300A, e.g. via network 103. User session management service 323A may process the requests, provide related internal requests to handwriting ingestion service 323B, obtain responses from handwriting ingestion service 323B, provide responses to client handwriting ingestion application 228 and store records of these requests and responses and other related data, e.g. in administrative data store 105 indexed by a user identifier and/or a user session identifier.
When a user indicates a desire to create a new handwriting sample set, the handwriting ingestion system may identify a desired style of communication for a user, such as general English language communication, formal Japanese language communication, technical Arabic language communication, and the like. The handwriting ingestion system may then determine a code-point sub-set, applicable to the desired style of communication, from one or more universal code-point sets, such as the set of standard Unicode character code-points.
For each code-point within the applicable code-point sub-set, the handwriting ingestion system may collect one or more digitized samples of a handwritten glyphs corresponding to the code-point. For example, as is explained in more detail below, handwriting ingestion application 228 may provide a user interface that presents a user of client device 200 with a visual display of one or more code-points and instructs the user to write out glyphs corresponding to the one or more code-points using digitizing marking device 220 to make one or more strokes on digitizing surface device 218. Depending on the desired style of communication and the user's individual writing style, a digitized glyph sample may be made up of one or more strokes and multiple digitized glyph samples may also be contained within a single stroke. Therefore, handwriting ingestion application 228 may (1) accommodate glyph samples being made up of multiple, non-sequential strokes, for example if the digitizing marking device leaves the digitizing surface device during the glyph sample capture (as may be the case when hand writing the lower case English letters “f,” “i,” “j,” “k,” “t,” and “x” for example) (2) provide a user with the opportunity to segment strokes into individual glyphs, and then provide the user with the opportunity to associate one or more strokes and/or one or more stroke segments with a code-point
Referring to FIG. 4 by way of example, the word “This” 403 is made up of four sequential characters represented by four distinct code-points: a “T” code-point 405A, an “h” code-point 405B, an “i” code-point 405C, and a “s” code-point 405D; a corresponding digitized hand-written sample 408 of the word “This” may be made up of four sequential glyphs: a “T” glyph 410A, an “h” glyph 410B, an “i” glyph 410C, and an “s” glyph 410D. In this example, the digitized hand-written sample of the word “This” is made up of four strokes 413A-D, however strokes 413A-D do not respectively correspond to glyphs 410A-D. Rather, a ‘horizontal’ stroke 413A and ‘vertical’ stroke 413B together make up “T” glyph 410A; a third stroke 413C makes up “h” glyph 410B, “s” glyph 410D, and part of “i” glyph 410C. A ‘dot’ stroke 413D makes up the remainder of the “i” glyph 410C.
In accordance with various embodiments, after a user finishes ‘dot’ stroke 413D, the user may then selectively segment third stroke 413C into an “h” stroke segment 415A, an “i” stroke segment 415B, and an “s” stroke segment 415C. The user may then associate ‘horizontal’ stroke 413A and ‘vertical’ stroke 413B as a digitized glyph sample for “T” code-point 405A, “h” stroke segment 415A as a digitized glyph sample for “h” code-point 405B, “i” stroke segment 415B and ‘dot’ stroke 413D as a digitized glyph sample for “i” code-point 405B, and “s” stroke segment 415C as a digitized glyph sample for “s” code-point 405D.
For each digitized glyph sample, the handwriting ingestion system may record code-point sample contextual data related to the digitized glyph sample. For example, the handwriting ingestion system may record where the digitized glyph sample was collected within the context of a group of glyphs (e.g. at the beginning, or in the middle of a sequence of glyphs written as a continuous stroke), whether the previous glyph, if any, had an upward or downward exit angle (described in more detail below) and a low or high exit point, and whether the subsequent glyph, if any, had an upward or downward entry angle and a low or high entry point, and the like.
For each stroke and/or stroke segment making up the digitized glyph sample, the handwriting ingestion system may also record stroke dimension data. For example, for each stroke, the handwriting ingestion system may obtain and record data values relating to the stroke overall temporal duration; the stroke's relative horizontal displacement over time, the stroke's relative vertical displacement displacement over time, the stroke's relative rotational displacement over time, the stroke's relative angular displacement over time, and the stroke's downward pressure over time.
Each glyph sample may be added to a code-point sample data set associated with the user (e.g. via a user identifier). The handwriting ingestion system will continue to collect digitized glyph samples for a given code-point until the system determines it can reproduce a full range of glyph variations of the code-point.

Handwriting Ingestion User Interface

FIGS. 5A-K illustrate various states of an exemplary user interface 500 provided by handwriting ingestion application 228 operating on a client device 200 for enabling a user of the client device to selectively provide digitized samples of the user's handwriting via a digitizing surface device in conjunction with a digitizing marking device. Exemplary user interface 500 may, for example, be rendered by display 215 in response to the execution of instructions of an instantiation of client handwriting ingestion application 228 operating on a client device 200. Handwriting ingestion UI 500 may be rendered in a window 503 including an instructive prompt 505, a sample text display 508, and an input reproduction rendering display 510.
In FIG. 5A, handwriting ingestion UI 500 is illustrated in an initial prompt state 500A. In initial prompt state 500A, instructive prompt 505 displays text instructing a user operating client device 200 to input the sample text (“This is a test”) displayed in sample text display 508 via digitizing surface device 218 and digitizing marking device 220. In the illustrated example, the displayed sample text includes: one instance of a “T” code-point; one instance of an “h” code-point; two instances of an “i” code-point; three instances of an “s” code-point; one instance of an “a” code-point; two instances of a “t” code-point; and one instance of an “e” code-point.
In FIG. 5B, handwriting ingestion UI 500 is illustrated in a first potential sample ingestion display state 500B. In first potential sample ingestion display state 500B, input reproduction rendering display 510 displays a visual rendering of input data corresponding to a first stroke 513A, e.g. obtained via digitizing surface device 218 in combination with digitizing marking device 220. The characteristics of such input data are discussed in more detail below, particularly in reference to FIGS. 7A-B.
In FIG. 5C, handwriting ingestion UI 500 is illustrated in a second potential sample ingestion display state 500C. In second potential sample ingestion display state 500C, input reproduction rendering display 510 displays a visual rendering of input data corresponding to first stroke 513A and a second stroke 513B, e.g. obtained via digitizing surface device 218 in combination with digitizing marking device 220 subsequent to the first stroke. Similar to the example discussed above with reference to FIG. 4, first and second strokes 513A-B make up a glyph sample corresponding to the first, “T” code-point of the sample text.
In FIG. 5D, handwriting ingestion UI 500 is illustrated in a third potential sample ingestion display state 500D. In third potential sample ingestion display state 500D, input reproduction rendering display 510 displays a visual rendering of input data corresponding to first stroke 513A, second stroke 513B, and a third stroke 513C. Similar to the example discussed above with reference to FIG. 4, third stroke 513C includes glyph samples corresponding to the “h” code-point, part of the “i” code-point, and one of the “s” code points of the sample text.
In FIG. 5E, handwriting ingestion UI 500 is illustrated in a fourth potential sample ingestion display state 500E. In fourth potential sample ingestion display state 500E, input reproduction rendering display 510 displays a visual rendering of input data corresponding to first stroke 513A, second stroke 513B, third stroke 513C, and a fourth stroke 513D. Similar to the example discussed above with reference to FIG. 4, fourth stroke 513D completes the glyph sample of the “i” code-point of the sample text began by stroke 513C.
In FIG. 5F, handwriting ingestion UI 500 is illustrated in a fifth potential sample ingestion display state 500F. In fifth potential sample ingestion display state 500F, input reproduction rendering display 510 displays a visual rendering of input data corresponding to first stroke 513A, second stroke 513B, third stroke 513C, and fourth stroke 513D, along with a fifth stroke 513E, a sixth stroke 513F, a seventh stroke 513G, an eighth stroke 513H, a ninth stroke 513I, a tenth stroke 513J, and an eleventh stroke 513K. First through eleventh strokes 513A-K collectively make up glyph samples corresponding to the sample text in sample text display 508.
In FIG. 5G, handwriting ingestion UI 500 is illustrated in a sample segmentation state 500G. In sample segmentation state 500G, instructive prompt 505 displays text instructing a user operating client device 200 to segment any multi-character strokes displayed in input reproduction rendering display 510. For example, the user may user a mouse or other pointer-based user input 213 to select segmentation points 515 within a stroke where one glyph sample ends and another begins. In the illustrated example, third stroke 513C is segmented at two segmentation points 515A-B, fifth stroke 513C is segmented at one segmentation point 515C, and eighth stroke 513H is segmented at two segmentation points 515D-E. As is shown in FIG. 5H, third stroke 513C is segmented into three stroke segments 520A-C, fifth stroke 513C is segmented into two stroke segments 520D-E, and eighth stroke 513H is segmented into three stroke segments 520F-H.
In FIG. 5H, handwriting ingestion UI 500 is illustrated in an initial stroke assignment state 500H.
