Electronic devices, such as personal computers, laptops, mobile phones, and the like are increasingly equipped with touch screens or similar interfaces that enable a user to provide input by writing or drawing with a stylus, pen, or finger. For instance, tablet computers, which include touch screens as the primary user interface, have become popular alternatives to conventional laptops with keyboards, mice, etc. The ability to draw or write by hand on the touch screen offers substantial flexibility regarding possible inputs. However, writing and drawing do not provide uniform results from user to user. People have different handwriting and drawing styles, they may write with different hands, or use different implements, etc. Consistently and accurately interpreting writing and drawing input is a challenge considering the proliferation of touch screen enabled devices.
Modern devices with touch screens typically include handwriting interpretation capability to some degree. However, the handwriting interpretation does not enable the use of drawings and/or symbols other than letters, numbers, and punctuation. The touch screen provides significant flexibility with respect to input that may be entered, but that input is limited by a lack of interpretation capability for shapes, drawings, non-text expressions, etc.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
A computerized method comprises receiving input from a user, extracting a shape from the received input, determining an entity associated with the extracted shape, the determined entity having a type, and rendering, by an annotation engine, the entity to the user based on the type.
Many of the attendant features will be more readily appreciated as the same becomes better understood by reference to the following detailed description considered in connection with the accompanying drawings.
The present description will be better understood from the following detailed description read in light of the accompanying drawings, wherein:
In
The detailed description provided below in connection with the appended drawings is intended as a description of a number of embodiments and is not intended to represent the only forms in which the embodiments may be constructed, implemented, or utilized. Although the embodiments may be described and illustrated herein as being implemented in devices such as a server, personal computer, mobile device, or the like, this is only an exemplary implementation and not a limitation. As those skilled in the art will appreciate, the present embodiments are suitable for application in a variety of different types of computing devices, for example, PCs, servers, laptop computers, tablet computers, etc.
The terms ‘computer’, ‘computing apparatus’, ‘mobile device’ and the like are used herein to refer to any device with processing capability such that it can execute instructions. Those skilled in the art will realize that such processing capabilities are incorporated into many different devices and therefore the terms ‘computer’ and ‘computing apparatus’ each may include PCs, servers, laptop computers, mobile telephones (including smart phones), tablet computers, media players, games consoles, personal digital assistants, and many other devices.
The electronic devices described below are configured to enhance user experience associated with drawing or otherwise inputting shape data into the electronic devices. Shape input data is identified and matched against known shape patterns and, when a match is found, an entity associated with the shape is determined. The entity is converted into an annotation for rendering and/or displaying to the user. The shape identification, entity determination, and annotation conversion may all be based on one or more context elements to increase the accuracy of the shape interpretation. In particular, elements of conversations held via the electronic devices may be used as context for the shape interpretation. Further, machine learning techniques may be applied based on a variety of feedback data to improve the accuracy, speed, and/or performance of the shape interpretation process.
The described devices enhance the ways people communicate and express themselves, enabling and simplifying the use of more than just writing and speech. Emojis, stickers, and other symbols are an increasingly popular way that people share their feelings and share experiences. People use pens to write, doodle, circle, create graphs, and other visual representations of their thoughts, and the disclosure interprets these visual representations. Using the described devices and/or methods, people can use doodles and gestures to communicate more openly and creatively.
Communication between people using the described shape extraction and interpretation methods may become faster, more efficient, and more intuitive as the shape interpretation provides increasingly accurate annotations for drawn shapes. Users may learn to rely more on intuitive drawings of commonly used expressions or complex ideas rather than attempting to write them in words, reducing time spent by the users and chance of user errors, and increasing user satisfaction and enjoyment with the communication user interface.
In general, the user interface 102 includes a graphics card for displaying data to the user and receiving data from the user. The user interface 102 may also include computer-executable instructions (e.g., a driver) for operating the graphics card. Further, the user interface 102 may include a display (e.g., a touch screen display or natural user interface) and/or computer-executable instructions (e.g., a driver) for operating the display. The user interface 102 may also include one or more of the following to provide data to the user or receive data from the user: speakers, a sound card, a camera, a microphone, a vibration motor, one or more accelerometers, a BLUETOOTH brand communication module, global positioning system (GPS) hardware, and a photoreceptive light sensor. For example, the user may input commands or manipulate data by moving the computing device in a particular way.
In an example, the user interface 102 includes a touch screen interface. The input interface 112 includes a layer or portion of the touch screen interface that detects the location of contact, depression, or the like on the touch screen interface. Contact on the touch screen interface, whether by a user's finger, pen, stylus, or the like, is detected by the input interface 112 and interpreted as input to the user interface 102. The output interface 114 includes a layer or portion of the touch screen interface that displays, renders, or otherwise outputs information to a user of the computing device 100. The output interface 114 may display colors, shapes, letters, or the like to communicate output information to a user of the electronic device.
Alternatively, or additionally, the input interface 112 may include a pen device linked to the computing device 100. The pen device may include pressure sensors, accelerometers, buttons, or the like that enable a user of the pen device to provide input to the computing device 100. The pen device sensors may detect movement, gestures, etc. of the pen device and provide the detected movement as input to the computing device 100. Further, the pen device may also function as an output interface 114 by providing information to a user of the electronic device from the electronic device. The pen device and computing device 100 may be in communication via the network interface 110 of the computing device 100.
In an example, the input interface 112 may include other interface, such as keyboards, mice, switches, buttons, microphones, cameras, motion detection, etc. These components of the input interface 112 further enable a user to input information into the computing device 100. For instance, a camera (e.g., a HoloLens, etc.) of input interface 112 may detect a user's gestures and interpret the gestures as a form of input information.
In an example, the output interface 114 may further include speakers, vibration components, projector components, etc. These components of the output interface 114 further enable the computing device 100 to communicate output information to a user. For instance, a vibration component of the output interface 114 may vibrate to provide a notification to the user of the computing device 100.
The handwriting processor 104 receives handwriting data, or “ink data”, and converts it into a form of data usable by other components of the electronic device. In an example, the handwriting processor 104 includes a writing to text converter 116 and a writing to shape converter 118. The handwriting processor 104 may identify received ink data as either written text or a written shape based on pattern recognition techniques. If the ink data is determined to be handwritten text, the ink data is converted to text data by the writing to text converter 116. However, if the ink data is determined to be a written shape, the ink data is converted to a shape, or shape data, by the writing to shape converter 118. In an example, received ink data may represent written text, drawn shapes, doodles, circling of text or objects, creating graphs, drawn expressions, gestures, etc.
The shape model 106 receives shapes and/or shape data and determines an associated entity based on the received shapes and/or shape data. In an example, the shape model 106 includes a mapping between shapes and entities, such that when a shape is received that is present in the mapping, the mapping provides an entity associated with the shape. The shape model 106 may apply pattern recognition to a received shape to identify the shape and/or match the received shape to a shape that is present in the mapping. In some examples, the shape model 106 may include machine learning, machine vision, static mathematical models, pattern matching, crowd-sourcing, etc.
The annotation engine 108 receives entities and/or entity data and renders and/or displays annotations associated with the received entities based on entity type and/or other defined entity display rules. The annotation engine 108 may include a mapping between defined entity types and rendered annotations. For instance, an entity that is identified as an emoticon entity type may be mapped to an emoticon annotation that renders as a small graphic to a user while an entity that is identified as a list entity type may be mapped to a list annotation that renders as a bullet list of text segments.
The network interface 110 provides an interface by which the computing device 100 may communicate with other electronic devices, computing devices, access points, or the like. The network interface 110 may provide access to one or more channels of network communication, including wired network connections, wireless network connections, etc. In some examples, components described as being part of the computing device 100 may instead be located outside of the computing device 100 and accessed by the electronic device via the network interface 110.
The ink data 220 is passed to the handwriting processor 204. The handwriting processor 204 determines whether the ink data 220 represents written text or drawn shapes based on pattern recognition. In an example, the handwriting processor determines that the ink data 220 represents a drawn shape, so the writing to shape converter 218 is used on the ink data 220.
Context elements 222 may be used in determining whether the ink data 220 is identified as handwriting or drawn shapes. Further, the context elements 222 may be used to determine a shape that the ink data 220 represents. Context elements 222 may include additional data and/or values that are available to the electronic device that provide context for the received ink data 220 or other types of data. For instance, context elements 222 may include a detected location of the electronic device (e.g., via a global positional system component, etc.), events from a calendar of a user of the electronic device, a timestamp associated with the ink data, information regarding what is currently displayed on the screen of the electronic device, time taken to draw the ink data, other sensor data (e.g., accelerometers, proximity sensors, etc.), an active application, application identifier, and/or application metadata, data exposed by an active application or background service via application programming interfaces (APIs), location data, received signals, etc. Pattern recognition of the handwriting processor 204 and/or the writing to shape converter 218 may take into account one or more context elements 222 in order to provide determinations based not just on the ink data 220, but also on the context in which the ink data 220 is received by the input interface 212. In an example, a context element of received ink data 220 may be that the ink data 220 is received when a messaging/chat application is active on the electronic device.
Additionally, or alternatively, the content of a conversation 230 (e.g., a time, place, person, or topic mentioned in the conversation, etc.), or a portion/subset of a conversation 230, in a messaging/chat application, or a similar application displayed or otherwise present on the electronic device, may be used as a context element or elements when identifying the ink data 220. Words, phrases, and/or combinations of words/phrases in a conversation 230 occurring on the electronic device may influence how the ink data 220 is identified and/or interpreted. For instance, written or drawn ink data 220 may be more likely to be identified as a common response phrase or drawing to a received message immediately preceding the receipt of the ink data 220 in a current conversation 230. If a received message includes the question, “What time is the meeting?”, a written or drawn response is more likely to be interpreted as a time in response to the question, such as “2:30” or “noon” or a drawing of a clock. Further, conversational patterns may be used, such that common exchanges between specific users may make identifying ink data 220 as a common response more likely, such as a conversational exchange between spouses that includes a message, “Heading home” and a common response of “See you soon!” and/or a drawing of a smiling face. Other details specific to a conversation 230, such as names of the participants, may be used as well. For instance, if a conversation 230 includes participants named “Jim” and “Dan”, ink data 220 is more likely to be interpreted as “Jim” or “Dan” than it otherwise would be if the participants had different names.
The writing to shape converter 218 outputs a shape 224 based on the ink data 220 and/or the context elements 222. In an example, the shape 224 is a digitized shape object that includes shape data and may include metadata, such as a timestamp, drawn order information, etc. In an example, the shape 224 may be a combination of more than one other shapes.
The shape model 206 receives the shape 224 and provides an entity 226 associated with the shape 224. The shape model 206 classifies the shape 224 as having to one or more shape types or categories, based on shape data, metadata, or the like of the shape 224, in order to provide a matching entity 226. The shape model 206 may assign one or more shape type identifiers to the shape 224 based on the shape types used to classify the shape 224. The shape model 206 may further receive context elements 222 as described above. The context elements 222 received by the shape model 206 may be the same or different from the context elements 222 received by the handwriting processor 204.
In an example, the shape model 206 includes a mapping between shapes and entities, such that when a shape is received that is present in the mapping, the mapping provides an entity associated with the shape. The shape model 206 may apply pattern recognition to a received shape in order to identify the shape and/or match the received shape to a shape that is present in the mapping. In some examples, the shape model 206 may include machine learning, machine vision, static mathematical models, pattern matching, crowd-sourcing, etc.
In an example, pattern recognition in the shape model 206 may include a plurality of defined shape patterns to which the shape model 206 matches a received shape 224. The shape model 206 and/or the plurality of defined shape patterns may include one or more pattern match thresholds, pattern match confidence levels, or the like, which determine whether a received shape 224 sufficiently matches a defined shape pattern to provide the entity associated with the matched shape pattern as output. For instance, a pattern match threshold for a shape pattern may be a percentage portion of the received shape 224 that matches the shape pattern, or a percentage of “closeness” that the received shape 224 is to matching the shape pattern. If a pattern match threshold of a shape pattern is 70%, a received shape 224 that is a 50% match to the shape pattern will not be considered a match, while a received shape 224 that is an 80% match of the shape pattern will be considered a match.
The pattern match threshold of a shape pattern may be affected/adjusted based on context elements 222, making shape pattern matching more or less likely depending on the context of the received shape 224. The defined shape patterns may include or be associated with context element patterns that, when matched to context elements 222 associated with the received shape 224, affect/adjust the likelihood of a match between the shape pattern and the received shape 224 and/or cause the received shape 224 to be matched to the shape pattern, and thereby influence the determination of an entity based on the received shape 224 and context elements 222. For instance, if the context elements 222 include elements that match a context element pattern indicating that the received shape 224 is associated with a conversation (e.g., conversation 230, etc.) in which a message was recently received, shape pattern thresholds of defined shape patterns associated with the matched context element pattern may be adjusted such that the received shape 224 is more likely to match the defined shape patterns, such as emoticon shape patterns that are common responses during conversations.
A match of a received shape 224 to a shape pattern of the shape model 206 and/or associated context elements 222 to a context element pattern may result in an entity 226 associated with the matched shape pattern and/or matched context element pattern being provided to the annotation engine 208. Entity 226 may have an entity type 232. An entity type 232 defines the entity such that components of the electronic device can render and/or interact with the entity. For instance, an entity may be of an expression type, a list type, a graph type, an emoticon type, a highlighting type, an event/time type, a location type, etc. It should be understood that other entity types 232 may be used without departing from the description herein. The type 232 of an entity 226 may be stored as metadata with the entity 226. In an example, the entity 226 may have one type 232, or alternatively, the entity 226 may have more than one type 232. The entity 226 may further include other data defining the specific entity 226 and/or providing information that may be useful in rendering or otherwise displaying the entity 226.
The entity 226 is received by the annotation engine 208, which converts the entity 226 into an annotation 228. The annotation engine 208 may also receive context elements 222 that may be used during the conversion to the annotation 228. The context elements 222 received and used by the annotation engine 208 may be the same or different from the context elements 222 used by the handwriting processor 204 and/or the shape model 206. For example, a context element 222 that includes currently active application information may be used by the annotation engine 208 to determine how to convert the entity 226 into an annotation 228. The entity 226 may be converted into an annotation 228 that is compatible with the currently active application based on the provided context element 222.
Once the annotation engine 208 converts the entity 226 into an annotation 228, the annotation 228 may be provided to the output interface 214 for rendering and/or display to a user of the electronic device. For instance, ink data 220 may be interpreted as an emoticon and the annotation 228 may be rendered as a version of the emoticon using the current font of the active application or as a graphical representation of the emoticon in the active application. Alternatively, the ink data 220 may be interpreted as a list of items and the annotation 228 may be rendered and/or displayed as a bulleted list, list with checkboxes, or the like on the output interface 214. The annotation 228 may also cause a new or different application to become active and render and/or display the annotation 228. For instance, if the annotation 228 represents an event object and a calendar application is not currently active, the calendar application may be activated on the output interface 214 and the event annotation 228 may be included in calendar application, where it may be highlighted to indicate that the event has been recently added.
In another example, a user is discussing plans with another person via an application on an electronic device. The other person sends a message to the user letting the user know that he/she is at a destination location where they planned to meet. The user responds by drawing a clock shape on the interface of the electronic device. Based on the context of the conversation, the clock shape is interpreted by the electronic device as an entity that responds to the user with a message including an estimated time of arrival at the destination location. The context elements considered by the electronic device may include the name of the destination location, the current location of the user, the current time, etc.
In a further example, a user is discussing movie plans with another person via an application on an electronic device. The user mentions in the conversation that he/she is not available at 7 PM. The user draws a bulleted list of possible movies and associated movie times. The electronic device interprets the drawn list as a bulleted list entity and, based on the user's previously mentioned unavailability at 7 PM, automatically crosses out the movie times at and/or around 7 PM.
In an example, an electronic device comprises a screen interface; at least one processor; and at least one memory comprising computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the electronic device to at least: receive input from the screen interface; extract a shape from the received input; determine an entity associated with the extracted shape based on at least one context element, the determined entity having a type; and display the entity on the screen interface, wherein the entity is displayed in a pattern based on the type.
The processor includes any quantity of processing units, and is programmed to execute computer-executable instructions for implementing aspects of the disclosure. The instructions may be performed by the processor or by multiple processors within the computing device, or performed by a processor external to the computing device. In some examples, the processor is programmed to execute instructions such as those illustrated in the figures (e.g.,
In some examples, the processor represents an implementation of analog techniques to perform the operations described herein. For example, the operations may be performed by an analog computing device and/or a digital computing device.
The computing device further has one or more computer readable media such as the memory area. The memory area includes any quantity of media associated with or accessible by the computing device. The memory area may be internal to the computing device, external to the computing device, or both. In some examples, the memory area includes read-only memory and/or memory wired into an analog computing device.
The memory area stores, among other data, one or more applications. The applications, when executed by the processor, operate to perform functionality on the computing device. Exemplary applications include mail application programs, web browsers, calendar application programs, address book application programs, messaging programs, media applications, location-based services, search programs, and the like. The applications may communicate with counterpart applications or services such as web services accessible via a network. For example, the applications may represent downloaded client-side applications that correspond to server-side services executing in a cloud.
The machine learning engine 334 may include one or more model performance goals which drive the model adjustments 338 determined by the engine 334. For instance, a model performance goal may be that the determined entity 326 is accepted as correct by the user at least a defined percentage (e.g., 70%, 80%, 90%, etc.) of the time. Alternatively, or additionally, a model performance goal of the machine learning engine 334 may be that the time required to convert ink data 320 to annotation 328 be less than a defined time amount (e.g., 500 milliseconds, 1 second, 1.5 seconds, etc.). The machine learning engine 334 may include more, fewer, or different model performance goals than those described here without departing from the scope of the description. In some examples, a user selects one or more performance goals for the machine learning engine 334. For instance, the user can select to have fast results or slower results that may be more accurate.
In order to pursue model performance goals, the machine learning engine 334 may apply model adjustments 338 to the shape model 306. The machine learning engine 334 may use any and/or all feedback data received (e.g., ink data 320, context elements 322, shape 324, entity 326, annotation 328, user feedback 336, etc.), as well as past model adjustments, past feedback data, results of past model adjustments, statistical analysis of past data, etc. when determining model adjustments.
Model adjustments 338 may include creating new shape patterns and/or associated entities, removing shape patterns and/or associated entities, adjusting shape patterns and/or associated entities, etc. Adjusting a shape pattern may include increasing and/or decreasing pattern match thresholds, creating new pattern match thresholds, or removing pattern match thresholds. A shape pattern may be adjusted so that future shapes may be more likely to match when they include portions that are similar to shapes that are known to have matched previously. Alternatively, or additionally, a shape pattern may be adjusted so that future shapes may be less likely to match when they include portions that are similar to shapes that are known to have failed to match previously. Further, a shape pattern may be associated with a new entity, and/or an association with an entity may be removed from a shape pattern.
User feedback 336 may be used as feedback data by the machine learning engine 334. For instance, when a user of the device accepts a displayed annotation 328, the machine learning engine 334 may use that user feedback 336 to indicate that the shape model provided an accurate entity 326 with respect to the received shape 324. The machine learning engine 334 may strengthen the association of the accepted entity 326 with shapes similar to the converted shape 324 and/or adjust pattern match thresholds of a matched shape pattern. Alternatively, when a user declines or rejects a displayed annotation 328, the machine learning engine 334 may use that user feedback 336 to indicate that the shape model provided an inaccurate entity 326 with respect to the received shape 324. The machine learning engine 334 may weaken or remove the association of the rejected entity 326 with shapes similar to the converted shape 324 and/or adjust pattern match thresholds of a matched shape pattern.
In an example, the machine learning engine 334 may make model adjustments 338 to the shape model 306 to determine effects, if any, of the adjustment 338 on the performance of the model 306. After a model adjustment 338 is made, the machine learning engine 334 may attribute performance changes to the model adjustment 338, to some degree. The machine learning engine 334 may make future model adjustments 338 based on performance change attributions of past adjustments.
The shape model 306 may be trained in a training mode, wherein users provide immediate feedback to ink data that they provide. For instance, users may draw shapes, symbols, and the like, and immediately label their drawings with an entity or entity type. Training mode data and associations may be collected from one or more users providing one or more drawings and associated entities. These associations may then be provided to devices as default or starter shape models, which may then be further adjusted by a machine learning engine as described above.
In an example, the machine learning engine 334 is disposed on the same electronic device as the shape model 306. Alternatively, the machine learning engine 334 may be disposed on a separate electronic device, server, or the like than the shape model 306. In this case, the machine learning engine 334 and shape model 306 may communicate over a network interface (e.g., network interface 110, etc.).
The machine learning engine 334 may gather feedback from the device specific to the shape model 306 and the adjustments provided by the machine learning engine 334 may be specific to the use of the device and/or behaviors of a user of the device. Alternatively, the machine learning engine 334 may gather feedback from more than one device or other feedback source. This may result in model adjustments 338 that are more “one size fits all” in nature.
In some examples, the machine learning engine 334 comprises a trained regressor such as a random decision forest, directed acyclic graph, support vector machine, neural network, or other trained regressor. The trained regressor may be trained using the input and feedback data described above. Examples of trained regressors include a convolutional neural network and a random decision forest. It should further be understood that the machine learning engine 334, in some examples, may operate according machine learning principles and/or techniques known in the art without departing from the systems and/or methods described herein.
A machine learning engine 334 may be available at the computing device 100 as shown in
The machine learning engine 334 is arranged to execute the methods described herein with respect to
In an example, the machine learning engine may make use of training data pairs when applying machine learning techniques and/or algorithms. Millions of training data pairs (or more) may be stored in a machine learning data structure. In some examples, a training data pair includes an input or feedback data value paired with a model adjustment value. The pairing of the two values demonstrates a relationship between the input or feedback data value and the model adjustment value that may be used by the machine learning engine 334 to determine future model adjustments 338 according to machine learning techniques and/or algorithms.
At 406, an entity associated with the extracted shape is determined if possible and the determined entity may have an entity type (e.g., a list, an event, a location, or an expression, etc.). In an example, determining the entity includes providing the extracted shape to a shape model as input and receiving the determined entity from the shape model as output. The shape model may include a plurality of shape patterns associated with entities. When the extracted shape received by the shape model matches a shape pattern of an entity, the entity associated with the matched shape pattern is provided by the shape model. Alternatively, or additionally, the shape model may include a plurality of context element patterns associated with entities. When the shape model receives at least one context element associated with an extracted shape as input and the at least one context element matches a context element pattern associated with an entity, the entity associated with the matched context element pattern is provided by the shape model.
In some examples, an entity may not be determined based on the extracted shape and/or context elements. When an entity is not or cannot be determined, the method 400 may end at 410. Alternatively, or additionally, the extracted shape may be provided, rendered, or otherwise displayed to a user in order for the user to take a desired action with the extracted shape (e.g., saving the extracted shape, sending the extracted shape, adjusting the extracted shape, etc.).
When an entity is determined, the entity is rendered, by an annotation engine, to the user based on the type at 408. For instance, the entity may be displayed to the user on a screen interface. Finally, the method 400 ends at 410.
At 508, an entity associated with the extracted shape is determined based on the extracted shape and the at least one context element. The determined entity may include an entity type. Determining the entity may include a shape model (e.g., shape model 106, 206, 306, etc.) receiving the extracted shape and the context element(s) as input. The shape model may then provide an entity associated with the extracted shape and context element(s). In a further example, a machine learning engine adjusts the shape model (e.g., adjusting at least one pattern match threshold of the shape model, etc.) based on feedback as described above.
In some examples, an entity may not be determined based on the extracted shape and/or context elements. When an entity is not or cannot be determined, the method 500 may end at 512. Alternatively, or additionally, the extracted shape may be provided, rendered, or otherwise displayed to a user in order for the user to take a desired action with the extracted shape (e.g., saving the extracted shape, sending the extracted shape, adjusting the extracted shape, etc.).
When an entity is determined, the entity is then rendered to the user, by an annotation engine, based on the entity type at 510. For instance, the entity may be displayed to the user on a screen interface. Finally, the method 500 ends at 512.
In an example, one or more computer storage media have computer-executable instructions that, upon execution by a processor, cause the processor to execute the method 500.
When an entity is determined at 606, the entity is displayed on the screen interface at 608, wherein the entity is displayed as an annotation based on the type, as described above. At 610, feedback may be received that may be associated with the determined entity, the extracted shape, the lack of a determined entity, etc. For instance, when an entity is determined and displayed on the screen interface, feedback may be received indicating the accuracy of the determined entity with respect to the received input and/or extracted shape. Alternatively, when an entity is not determined, feedback may be received indicating an entity and/or entity type with which the received input is intended to be associated.
When feedback is received, the shape model is adjusted at 612 based on machine learning using the received feedback. Alternatively, when feedback is not received, the shape model is not adjusted. In either case, the interface may be ready to receive additional input at the screen interface again at 602.
In an example, a user may send a friend a message about a movie that they saw the night before using a messaging application on an electronic device (e.g., computing device 100, etc.). The user may transcribe the message with a pen and/or stylus on a touch screen of the electronic device because she finds it faster and more natural. The user may draw a laughing face when recounting a funny scene in the movie. The electronic device may detect that the user has drawn a face and send it as an emoji to the friend with the rest of the message via the messaging application. The custom emoji helps the friend understand the user's sentiment more clearly.
In another example, a user may send his spouse a grocery list via a messaging application on an electronic device. The user may draw bullets for each item in the list, which may indicate to the electronic device that the drawn items are a list. When the message with the list is sent, it may be received by the spouse's phone. A messaging application on the spouse's phone may notify her that she's received a list of items, which she may then view in a to-do list application or the like, enabling her to check off items as she finds them.
A user may also use an electronic device to let her spouse know that she'll be late for dinner. The user may draw a clock on the touch screen in an active messaging application window. The electronic device may interpret the clock according to the context of the messaging application and suggest that the user is trying to send a “Running late!” message. The user may confirm that this is correct, causing the message to be sent to the user's spouse.
In another scenario, a user may draw a street intersection that may include street names or other identifying information. The electronic device may interpret the street intersection as a location on a map and may provide a map image of the drawn intersection and/or a link to an online map site or application that is focused on the drawn location.
A sample scenario contemplates a user writing an address. The electronic device may interpret the address as a location on a map and may provide a map image of the address and/or a link to an online map site or application that is focused on the address.
Another sample scenario contemplates a user writing a phone number. The electronic device may interpret the phone number as associated with an address book contact and/or contact list and may display contact information associated with the written phone number, if such a contact exists. If the phone number is not present in the contact list, a new entry in the contact list associated with the phone number may be created, etc.
In an example, a user may draw a drawing or expression that is not matched to a pattern by the electronic device. The electronic device may convert the drawing to an image file and associated the image file with a communication the user may currently be sending. For instance, a drawing image file may be attached to an email that the user was drafting, or a message that the user was writing.
