A user may create content via a productivity application for presentation to others, either in real time or in advance. As an example, a teacher may create a lesson plan including various math problems, or may work a number of math problems in the classroom to demonstrate to students how to solve the math problems. Oftentimes, such as with the above example, content is created in a step-by-step manner, wherein presenting or revealing the content in a step-by-step manner provides context and insight to the user that may otherwise not be understood.
Additionally, a user may add content to a document for later review. As an example, a student may complete a homework assignment, such as fill-in-the-blank worksheet, and may later want to review the homework assignment when studying for a test. The user may wish to self-test by hiding the answers and then later revealing the answers for checking correctness.
Document content is input via various methods, such as from input devices such as mice, keyboards, remote controls, and the like, or from natural user input (NUI) methods including those relying on speech recognition, touch and stylus recognition, gesture recognition both on screen and adjacent to the screen, air gestures, head and eye tracking, voice and speech, vision, touch, hover gestures, and machine intelligence.
Using digital ink input in an application produces a digital artifact which, although “handwritten,” may be stored, copied, transmitted, edited, and annotated. In an educational environment, for example, applications incorporating digital ink input are oftentimes used as an educational resource for taking notes, to create lesson plans, for completing homework assignments, and the like.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description section. This summary is not intended to identify all features of the claimed subject matter, nor is it intended as limiting the scope of the claimed subject matter.
Systems and methods are provided herein to enable improved usability of productivity applications that enables incremental replay of document content without the need for a user to intentionally structure the content in an ordered fashion. An electronic workspace internally represents its displayed content in a graph. Nodes are associated with types of content. Nodes that represent the document content have associated view elements that can know how to render that node type.
When the electronic workspace wants to render a page, it walks the graph and renders the view elements. A time travel effect can be achieved by traversing the graph in order of structural hierarchy or in order of when items were added, and marking the relevant items as objects to be rendered, hidden, or rendered semi-transparently, and then re-displaying the relevant portion of the screen. Traversing can be limited to the current viewport, or the current selection state of the nodes, or other characteristics. By employing the present disclosure, an improved user experience is provided and less memory and fewer processing resources are expended to provide incremental replay of document content.
The details of one or more aspects are set forth in the accompanying drawings and description below. Other features and advantages will be apparent from a reading of the following detailed description and a review of the associated drawings. It is to be understood that the following detailed description is explanatory only and is not restrictive; the proper scope of the present disclosure is set by the claims.
The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate various aspects of the present disclosure. In the drawings:
The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar elements. While aspects of the present disclosure may be described, modifications, adaptations, and other implementations are possible. For example, substitutions, additions, or modifications may be made to the elements illustrated in the drawings, and the methods described herein may be modified by substituting, reordering, or adding stages to the disclosed methods. Accordingly, the following detailed description does not limit the present disclosure, but instead, the proper scope of the present disclosure is defined by the appended claims. Examples may take the form of a hardware implementation, or an entirely software implementation, or an implementation combining software and hardware aspects. The following detailed description is, therefore, not to be taken in a limiting sense.
Systems and methods are provided herein for enabling incremental replay of document content without the need for a user to intentionally structure the content in an ordered fashion.
With reference now to
A user 110 may use an application 108 on the computing device 102 for a variety of tasks, which may include, for example, to write, calculate, draw, take and organize notes, prepare and organize presentations, send and receive electronic mail, make music, and the like. Applications 108 may include thick client applications 108, which may be stored locally on the computing device 102, or may include thin client applications 108 (i.e., web applications) that reside on a remote server and accessible over a network, such as the Internet or an intranet. A thin client application 108 may be hosted in a browser-controlled environment or coded in a browser-supported language and reliant on a common web browser to render the application 108 executable on the computing device 102. According to an aspect, the application 108 is a program that is launched and manipulated by an operating system, and manages content 112 within an electronic document 114 and published on a display screen 104.
The content 112 in an electronic document 114 may vary according the program used to provide the electronic document 114. The content 112 may comprise one or more objects present or imbedded in the electronic document 114 including, but not limited to: text (including text containers), numeric data, macros, images, movies, sound files, and metadata. According to one example, the content 112 includes a plurality of digital strokes, sometimes referred to herein as “inking” input, wherein a stroke is a data object that is collected from a pointing device, such as a tablet pen, a finger, or a mouse. The stroke can be created and manipulated programmatically, and can be represented visually on an ink-enabled element, such as the ink canvas. In some examples, a stroke contains information about both its position and appearance.
In various aspects, the data comprising the content 112 are stored in an elemental form by the electronic document 114, such as in Extensible Markup Language (XML) or Java Script Object Notation (JSON) elements or another declaratory language interpretable by a schema. The schema may define sections or content item via tags and may apply various properties to content items via direct assignment or hierarchical inheritance. For example, an object comprising text may have its typeface defined in its element definition (e.g., “<text typeface=garamond>example text</text>”) or defined by a stylesheet or an element above the object in the document's hierarchy from which the element depends.
With reference still to
According to aspects, the incremental content replayer 116 includes: an input manager 120; a replay order generator 122; a state selector 124; and a UI engine 126. The input manager 120 is illustrative of a software module, system, or device operative to receive a selection input. According to aspects, the selection input includes a physical act or motion performed on or by an input device 106 (e.g., finger, pen/stylus, mouse) at a position of a user-controlled cursor (such as a mouse cursor or touch-point on a touch-screen interface) that is interpreted as a selection interaction. According to an example, the input device 106 is a pointing device used to specify a position (e.g., x, y coordinates) on a graphical user interface (GUI), and manipulate on-screen objects.
According to one aspect, the input manager 120 is operative to receive an indication of a selection to replay content, for example, via a selection of a functionality control. According to another aspect, the input manager 120 is operative to receive a selection of content for incremental replay. In one example, the input manager 120 identifies the position of the user-controlled cursor (e.g., mouse cursor or touch-point) to determine an area of interest 402, and determine if any content elements are within the area of interest 402.
According to an aspect, the replay order generator 122 is illustrative of a software module, system, or device operative to establish a replay order of content elements that have been authored within the area of interest 402. According to an example, the replay order generator assigns a replay-order value to each content element. In one example, the replay-order value is based on the content element's structural hierarchy in back-to-front order (i.e., z-order). In one example, ordering may be implicit in the existing structure, and identification of the structural hierarchy is performed by the replay order generator 122. In another example, the replay-order value is based on a timestamp associated with a modification (e.g., input or content authoring) of the content element. Accordingly, newer or more recently added input has a higher replay-order value, and older or previously added input has a lower replay-order value. In another example, replay order value is based on a combination of structural hierarchy and timestamp association.
The state selector 124 is illustrative of a software module, system, or device operative to determine a selected or implicitly selected replay mode. In some examples, the determination is made based on a selected command. If the replay mode is determined to be backward, the state selector 124 is operative to identify the foremost content element that is currently displayed (in the area of interest 402) according to the replay-order value, and change the display state of the content element to hide. If the replay mode is determined to be forward, the state selector 124 is operative to identify the backmost content element according to the replay-order value, and change the display state of the content element to be shown.
UI engine 126 is illustrative of a software module, system, or device operative to update the GUI to according to the state change. For example, the UI engine 126 is operative to update the GUI to incrementally display content in a backward or forward direction.
Some various example scenarios in which it may be beneficial to a user to incrementally replay content include: a teacher lecturing from prepared content in front of a class; a teacher revisiting an item that a student has a question about during a lecture; a teacher reviewing a student's work and trying to understand the student's thinking/processing; and students testing/quizzing themselves to study.
Upon selection of the entry point 204, and with reference now to
According to examples, the canvas overlay 302 provides a prompt 304 that instructs the user to select an area of interest 402 for replay of the content within the selected area of interest 402. In one example, the cursor becomes a marquee selector 306 that enables the user to select content displayed on the canvas 206 for replay. In another example, a “replay everything on this page” functionality command 308 is provided that enables the user to select to replay all the content currently displayed on the canvas 206. If another page is selected, the unselected content 310 displayed below the canvas overlay 302 changes to the content on the newly-selected page.
With reference now to
According to an aspect and with reference now to
As an example and as illustrated in
With reference now to
Similarly to when a portion of displayed content is selected for replay as described above with respect to
According to an aspect and as illustrated in
As another example of a situation in which it may be beneficial to a user to incrementally replay content includes learning to draw a Far East language character, such as a Kanji character, which is composed of specific strokes that are supposed to be made in a certain fashion and order. ). As illustrated in
Annotations 1304 have a visible display state when the replay reaches their position in the replay order, but have a hidden display state at other times during the replay, as is illustrated in
As another example of a situation in which it may be beneficial to a user to incrementally replay content includes students testing/quizzing themselves to study or a teacher lecturing from prepared content. For example, as illustrated in
Having described an example operating environment and various examples,
The method 1900 proceeds to OPERATION 1906, where a selection to replay content in an area of interest 402 is received. For example, a user may select a “Replay” entry point 204 command and may then make a selection of a portion of content displayed on the canvas 206, or may select to replay everything on the page or everything currently displayed on the canvas 206.
The method 1900 proceeds to OPERATION 1908, where a replay order of the content of interest (i.e., replay content or content that is located in the selected area of interest 402) is established. For example, the content is assigned a replay-order value. In one example, the replay-order value is based on the content's structural hierarchy in back-to-front order (i.e., z-order). It is possible in this case that ordering is implicit in existing structure, and no computation is required as this stage. In another example, the replay-order value is based on a timestamp associated with a modification (e.g., input) of the content. Accordingly, newer or more recently added input has a higher replay-order value, and older or previously added input has a lower replay-order value. In another example, replay order value is based on a combination of structural hierarchy and timestamp association. For example, an object that was first added to the canvas 206, may have been modified at a later time to adjust its display properties (e.g., a spelling correction, a size/color/font adjustment, a theme application) and the replay-order may treat the modification as a separate element to display during replay or incorporate the modification when the object is first displayed during replay.
In various aspects, the user may set whether the z-order for replays includes or excludes display property changes for objects as part of the z-order. For example, when display property changes are included in the z-order, when the replay reaches the display property change the display property change will be applied (forward replay mode) or removed (backward replay mode). When the display property changes are excluded from the z-order, objects that are made visible will be displayed with their last-applied display properties.
The method 1900 continues to OPTIONAL OPERATION 1910, where the content in the selected area of interest 402 is parsed, and the content elements within the selected area are counted, providing a range of replay from the beginning to the end. In some examples, the range of replay can be used to update the GUI to include replay functionality UI controls, such as a slider control (e.g., scrub bar 510) showing a range of steps. At OPTIONAL OPERATION 1912, one or more replay functionality UI controls (e.g., replay commands 502) are displayed, and at OPTIONAL OPERATION 1914, a selection of a replay command 502 is received. For example, a user may select the rewind command 508, the fast forward command 506, the play/pause command 504, a position along the scrub bar 510, provide keyboard input, etc. As should be appreciated, this operation is optional. For example, a replay mode (forward or backward) may be implicitly established via a user input (e.g., via a selection of a button or mouse wheel+ctrl+shift), and UI functionality controls may not be provided.
The method 1990 continues to a DECISION OPERATION 1916, where a determination of a replay mode is made. In some examples, the determination is made based on a selected replay command 502. If the replay mode is determined to be backward, for example, the rewind command 508 is selected, the scrub bar 510 is selected or moved in a backward direction indicating a selection to play previous content, etc., the method 1900 continues to OPERATION 1918, where the foremost content that is currently displayed according to the replay-order value is identified, and the display state of the content is changed to hidden so as to incrementally hide the content.
If the replay mode is determined to be forward, for example, the fast forward command 506 is selected, the scrub bar 510 is selected or moved in a forward direction indicating a selection to play succeeding content, the play/pause command 504 is selected, etc., the method 1900 continues to OPERATION 1920, where the backmost content according to the replay-order value is identified, and the display state of the content is changed to visible. As will be appreciated, if the replay mode is determined to be forward and is designated to start at a given point (e.g., the beginning of the replay order) all content ahead of the given point will have its display state set to hidden.
The method 1990 continues to OPERATION 1922, where the display of the replay content 404 is updated in the GUI 202. When the determination made at DECISION OPERATION 1916 is that the selected command is the play/pause command 504, OPERATIONS 1920 and 1922 may repeat multiple times until each piece of content in the area of interest 402 is revealed so as to incrementally show the content.
Method 1900 may repeat OPERATIONS 1914-1922 multiple times according to a number of times the user selects to hide or reveal content in the selected area of interest. The method 1900 ends at OPERATION 1998. Method 1900 may be repeated continuously or a predetermined number of times with the same or opposite replay modes to loop the replay of the content or walk back and forth through the replay order.
While implementations have been described in the general context of program modules that execute in conjunction with an application program that runs on an operating system on a computer, those skilled in the art will recognize that aspects may also be implemented in combination with other program modules. Generally, program modules include routines, programs, components, data structures, and other types of structures that perform particular tasks or implement particular abstract data types.
The aspects and functionalities described herein may operate via a multitude of computing systems including, without limitation, desktop computer systems, wired and wireless computing systems, mobile computing systems (e.g., mobile telephones, netbooks, tablet or slate type computers, notebook computers, and laptop computers), hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, minicomputers, and mainframe computers.

The term computer readable media, as used herein, includes computer storage media apparatuses and articles of manufacture. Computer storage media include volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information, such as computer readable instructions, data structures, or program modules. The system memory 2004, the removable storage device 2009, and the non-removable storage device 2010 are all computer storage media examples (i.e., memory storage). According to an aspect, computer storage media include RAM, ROM, electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other article of manufacture which can be used to store information and which can be accessed by the computing device 2000. According to an aspect, any such computer storage media is part of the computing device 2000. Computer storage media do not include a carrier wave or other propagated data signal.
According to an aspect, communication media are embodied by computer readable instructions, data structures, program modules, or other data in a modulated data signal, such as a carrier wave or other transport mechanism, and include any information delivery media. According to an aspect, the term “modulated data signal” describes a signal that has one or more characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media include wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, radio frequency (RF), infrared, and other wireless media.
According to an aspect, one or more application programs 2150 are loaded into the memory 2162 and run on or in association with the operating system 2164. Examples of the application programs include phone dialer programs, e-mail programs, personal information management (PIM) programs, word processing programs, spreadsheet programs, Internet browser programs, messaging programs, and so forth. According to an aspect, incremental content replayer 116 is loaded into memory 2162. The system 2102 also includes a non-volatile storage area 2168 within the memory 2162. The non-volatile storage area 2168 is used to store persistent information that should not be lost if the system 2102 is powered down. The application programs 2150 may use and store information in the non-volatile storage area 2168, such as e-mail or other messages used by an e-mail application, and the like. A synchronization application (not shown) also resides on the system 2102 and is programmed to interact with a corresponding synchronization application resident on a host computer to keep the information stored in the non-volatile storage area 2168 synchronized with corresponding information stored at the host computer. As should be appreciated, other applications may be loaded into the memory 2162 and run on the mobile computing device 2100.
According to an aspect, the system 2102 has a power supply 2170, which is implemented as one or more batteries. According to an aspect, the power supply 2170 further includes an external power source, such as an AC adapter or a powered docking cradle that supplements or recharges the batteries.
According to an aspect, the system 2102 includes a radio 2172 that performs the function of transmitting and receiving radio frequency communications. The radio 2172 facilitates wireless connectivity between the system 2102 and the “outside world,” via a communications carrier or service provider. Transmissions to and from the radio 2172 are conducted under control of the operating system 2164. In other words, communications received by the radio 2172 may be disseminated to the application programs 2150 via the operating system 2164, and vice versa.
According to an aspect, the visual indicator 2120 is used to provide visual notifications and/or an audio interface 2174 is used for producing audible notifications via the audio transducer 2125. In the illustrated example, the visual indicator 2120 is a light emitting diode (LED) and the audio transducer 2125 is a speaker. These devices may be directly coupled to the power supply 2170 so that when activated, they remain on for a duration dictated by the notification mechanism even though the processor 2160 and other components might shut down for conserving battery power. The LED may be programmed to remain on indefinitely until the user takes action to indicate the powered-on status of the device. The audio interface 2174 is used to provide audible signals to and receive audible signals from the user.
