     DESCRIPTION 
     A physical environment refers to a physical place that people can sense and/or interact with without aid of electronic devices. The physical environment may include physical features such as a physical surface or a physical object. For example, the physical environment corresponds to a physical park that includes physical trees, physical buildings, and physical people. People can directly sense and/or interact with the physical environment such as through sight, touch, hearing, taste, and smell. In contrast, an extended reality (XR) environment refers to a wholly or partially simulated environment that people sense and/or interact with via an electronic device. For example, the XR environment may include augmented reality (AR) content, mixed reality (MR) content, virtual reality (VR) content, and/or the like. With an XR system, a subset of a person&#39;s physical motions, or representations thereof, are tracked, and, in response, one or more characteristics of one or more virtual objects simulated in the XR environment are adjusted in a manner that comports with at least one law of physics. As an example, the XR system may detect movement of the electronic device presenting the XR environment (e.g., a mobile phone, a tablet, a laptop, a head-mounted device, and/or the like) and, in response, adjust graphical content and an acoustic field presented by the electronic device to the person in a manner similar to how such views and sounds would change in a physical environment. In some situations (e.g., for accessibility reasons), the XR system may adjust characteristic(s) of graphical content in the XR environment in response to representations of physical motions (e.g., vocal commands). 
     There are many different types of electronic systems that enable a person to sense and/or interact with various XR environments. Examples include head-mountable systems, projection-based systems, heads-up displays (HUDs), vehicle windshields having integrated display capability, windows having integrated display capability, displays formed as lenses designed to be placed on a person&#39;s eyes (e.g., similar to contact lenses), headphones/earphones, speaker arrays, input systems (e.g., wearable or handheld controllers with or without haptic feedback), smartphones, tablets, and desktop/laptop computers. A head-mountable system may have one or more speaker(s) and an integrated opaque display. Alternatively, a head-mountable system may be configured to accept an external opaque display (e.g., a smartphone). The head-mountable system may incorporate one or more imaging sensors to capture images or video of the physical environment, and/or one or more microphones to capture audio of the physical environment. Rather than an opaque display, a head-mountable system may have a transparent or translucent display. The transparent or translucent display may have a medium through which light representative of images is directed to a person&#39;s eyes. The display may utilize digital light projection, OLEDs, LEDs, uLEDs, liquid crystal on silicon, laser scanning light sources, or any combination of these technologies. The medium may be an optical waveguide, a hologram medium, an optical combiner, an optical reflector, or any combination thereof. In some implementations, the transparent or translucent display may be configured to become opaque selectively. Projection-based systems may employ retinal projection technology that projects graphical images onto a person&#39;s retina. Projection systems also may be configured to project virtual objects into the physical environment, for example, as a hologram or on a physical surface. 
     Numerous details are described in order to provide a thorough understanding of the example implementations shown in the drawings. However, the drawings merely show some example aspects of the present disclosure and are therefore not to be considered limiting. Those of ordinary skill in the art will appreciate that other effective aspects and/or variants do not include all of the specific details described herein. Moreover, well-known systems, methods, components, devices, and circuits have not been described in exhaustive detail so as not to obscure more pertinent aspects of the example implementations described herein. 
     As noted above, a person may keep a list of tasks and mark tasks in the list as the tasks are completed. However, in various circumstances, the person may forget to utilize the list or forget to mark a task after it has been completed. Accordingly, in various implementations, a device displays a task list including a plurality of task elements respectively associated with a plurality of tasks. Further, as the device detects completion of a task of the plurality of tasks, e.g., in a video of the physical environment in which the task is completed, the device changes display of the corresponding task element. For example, in various implementations, the device displays a line through the task element or removes the task element from the task list. 
       FIG.  1    is a block diagram of an example operating environment  100  in accordance with some implementations. While pertinent features are shown, those of ordinary skill in the art will appreciate from the present disclosure that various other features have not been illustrated for the sake of brevity and so as not to obscure more pertinent aspects of the example implementations disclosed herein. To that end, as a non-limiting example, the operating environment  100  includes a controller  110  and an electronic device  120 . 
     In some implementations, the controller  110  is configured to manage and coordinate an XR experience for the user. In some implementations, the controller  110  includes a suitable combination of software, firmware, and/or hardware. The controller  110  is described in greater detail below with respect to  FIG.  2   . In some implementations, the controller  110  is a computing device that is local or remote relative to the physical environment  105 . For example, the controller  110  is a local server located within the physical environment  105 . In another example, the controller  110  is a remote server located outside of the physical environment  105  (e.g., a cloud server, central server, etc.). In some implementations, the controller  110  is communicatively coupled with the electronic device  120  via one or more wired or wireless communication channels  144  (e.g., BLUETOOTH, IEEE 802.11x, IEEE 802.16x, IEEE 802.3x, etc.). In another example, the controller  110  is included within the enclosure of the electronic device  120 . In some implementations, the functionalities of the controller  110  are provided by and/or combined with the electronic device  120 . 
     In some implementations, the electronic device  120  is configured to provide the XR experience to the user. In some implementations, the electronic device  120  includes a suitable combination of software, firmware, and/or hardware. According to some implementations, the electronic device  120  presents, via a display  122 , XR content to the user while the user is physically present within the physical environment  105  that includes a table  107  within the field-of-view  111  of the electronic device  120 . As such, in some implementations, the user holds the electronic device  120  in his/her hand(s). In some implementations, while providing XR content, the electronic device  120  is configured to display a virtual object (e.g., a virtual cylinder  109 ) and to enable video pass-through of the physical environment  105  (e.g., including a representation  117  of the table  107 ) on a display  122 . The electronic device  120  is described in greater detail below with respect to  FIG.  3   . 
     According to some implementations, the electronic device  120  provides an XR experience to the user while the user is virtually and/or physically present within the physical environment  105 . 
     In some implementations, the user wears the electronic device  120  on his/her head. For example, in some implementations, the electronic device includes a head-mounted system (HMS), head-mounted device (HMD), or head-mounted enclosure (HME). As such, the electronic device  120  includes one or more XR displays provided to display the XR content. For example, in various implementations, the electronic device  120  encloses the field-of-view of the user. In some implementations, the electronic device  120  is a handheld device (such as a smartphone or tablet) configured to present XR content, and rather than wearing the electronic device  120 , the user holds the device with a display directed towards the field-of-view of the user and a camera directed towards the physical environment  105 . In some implementations, the handheld device can be placed within an enclosure that can be worn on the head of the user. In some implementations, the electronic device  120  is replaced with an XR chamber, enclosure, or room configured to present XR content in which the user does not wear or hold the electronic device  120 . 
       FIG.  2    is a block diagram of an example of the controller  110  in accordance with some implementations. While certain specific features are illustrated, those skilled in the art will appreciate from the present disclosure that various other features have not been illustrated for the sake of brevity, and so as not to obscure more pertinent aspects of the implementations disclosed herein. To that end, as a non-limiting example, in some implementations the controller  110  includes one or more processing units  202  (e.g., microprocessors, application-specific integrated-circuits (ASICs), field-programmable gate arrays (FPGAs), graphics processing units (GPUs), central processing units (CPUs), processing cores, and/or the like), one or more input/output (I/O) devices  206 , one or more communication interfaces  208  (e.g., universal serial bus (USB), FIREWIRE, THUNDERBOLT, IEEE 802.3x, IEEE 802.11x, IEEE 802.16x, global system for mobile communications (GSM), code division multiple access (CDMA), time division multiple access (TDMA), global positioning system (GPS), infrared (IR), BLUETOOTH, ZIGBEE, and/or the like type interface), one or more programming (e.g., I/O) interfaces  210 , a memory  220 , and one or more communication buses  204  for interconnecting these and various other components. 
     In some implementations, the one or more communication buses  204  include circuitry that interconnects and controls communications between system components. In some implementations, the one or more I/O devices  206  include at least one of a keyboard, a mouse, a touchpad, a joystick, one or more microphones, one or more speakers, one or more image sensors, one or more displays, and/or the like. 
     The memory  220  includes high-speed random-access memory, such as dynamic random-access memory (DRAM), static random-access memory (SRAM), double-data-rate random-access memory (DDR RAM), or other random-access solid-state memory devices. In some implementations, the memory  220  includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid-state storage devices. The memory  220  optionally includes one or more storage devices remotely located from the one or more processing units  202 . The memory  220  comprises a non-transitory computer readable storage medium. In some implementations, the memory  220  or the non-transitory computer readable storage medium of the memory  220  stores the following programs, modules and data structures, or a subset thereof including an optional operating system  230  and an XR experience module  240 . 
     The operating system  230  includes procedures for handling various basic system services and for performing hardware dependent tasks. In some implementations, the XR experience module  240  is configured to manage and coordinate one or more XR experiences for one or more users (e.g., a single XR experience for one or more users, or multiple XR experiences for respective groups of one or more users). To that end, in various implementations, the XR experience module  240  includes a data obtaining unit  242 , a tracking unit  244 , a coordination unit  246 , and a data transmitting unit  248 . 
     In some implementations, the data obtaining unit  242  is configured to obtain data (e.g., presentation data, interaction data, sensor data, location data, etc.) from at least the electronic device  120  of  FIG.  1   . To that end, in various implementations, the data obtaining unit  242  includes instructions and/or logic therefor, and heuristics and metadata therefor. 
     In some implementations, the tracking unit  244  is configured to map the physical environment  105  and to track the position/location of at least the electronic device  120  with respect to the physical environment  105  of  FIG.  1   . To that end, in various implementations, the tracking unit  244  includes instructions and/or logic therefor, and heuristics and metadata therefor. 
     In some implementations, the coordination unit  246  is configured to manage and coordinate the XR experience presented to the user by the electronic device  120 . To that end, in various implementations, the coordination unit  246  includes instructions and/or logic therefor, and heuristics and metadata therefor. 
     In some implementations, the data transmitting unit  248  is configured to transmit data (e.g., presentation data, location data, etc.) to at least the electronic device  120 . To that end, in various implementations, the data transmitting unit  248  includes instructions and/or logic therefor, and heuristics and metadata therefor. 
     Although the data obtaining unit  242 , the tracking unit  244 , the coordination unit  246 , and the data transmitting unit  248  are shown as residing on a single device (e.g., the controller  110 ), it should be understood that in other implementations, any combination of the data obtaining unit  242 , the tracking unit  244 , the coordination unit  246 , and the data transmitting unit  248  may be located in separate computing devices. 
     Moreover,  FIG.  2    is intended more as functional description of the various features that may be present in a particular implementation as opposed to a structural schematic of the implementations described herein. As recognized by those of ordinary skill in the art, items shown separately could be combined and some items could be separated. For example, some functional modules shown separately in  FIG.  2    could be implemented in a single module and the various functions of single functional blocks could be implemented by one or more functional blocks in various implementations. The actual number of modules and the division of particular functions and how features are allocated among them will vary from one implementation to another and, in some implementations, depends in part on the particular combination of hardware, software, and/or firmware chosen for a particular implementation. 
       FIG.  3    is a block diagram of an example of the electronic device  120  in accordance with some implementations. While certain specific features are illustrated, those skilled in the art will appreciate from the present disclosure that various other features have not been illustrated for the sake of brevity, and so as not to obscure more pertinent aspects of the implementations disclosed herein. To that end, as a non-limiting example, in some implementations the electronic device  120  includes one or more processing units  302  (e.g., microprocessors, ASICs, FPGAs, GPUs, CPUs, processing cores, and/or the like), one or more input/output (I/O) devices and sensors  306 , one or more communication interfaces  308  (e.g., USB, FIREWIRE, THUNDERBOLT, IEEE 802.3x, IEEE 802.11x, IEEE 802.16x, GSM, CDMA, TDMA, GPS, IR, BLUETOOTH, ZIGBEE, and/or the like type interface), one or more programming (e.g., I/O) interfaces  310 , one or more XR displays  312 , one or more optional interior- and/or exterior-facing image sensors  314 , a memory  320 , and one or more communication buses  304  for interconnecting these and various other components. 
     In some implementations, the one or more communication buses  304  include circuitry that interconnects and controls communications between system components. In some implementations, the one or more I/O devices and sensors  306  include at least one of an inertial measurement unit (IMU), an accelerometer, a gyroscope, a thermometer, one or more physiological sensors (e.g., blood pressure monitor, heart rate monitor, blood oxygen sensor, blood glucose sensor, etc.), one or more microphones, one or more speakers, a haptics engine, one or more depth sensors (e.g., a structured light, a time-of-flight, or the like), and/or the like. 
     In some implementations, the one or more XR displays  312  are configured to provide the XR experience to the user. In some implementations, the one or more XR displays  312  correspond to holographic, digital light processing (DLP), liquid-crystal display (LCD), liquid-crystal on silicon (LCoS), organic light-emitting field-effect transitory (OLET), organic light-emitting diode (OLED), surface-conduction electron-emitter display (SED), field-emission display (FED), quantum-dot light-emitting diode (QD-LED), micro-electro-mechanical system (MEMS), and/or the like display types.

In some implementations, the data transmitting unit  348  is configured to transmit authentication credentials to the electronic device. To that end, in various implementations, the data transmitting unit  348  includes instructions and/or logic therefor, and heuristics and metadata therefor. 
     Although the data obtaining unit  342 , the task list unit  344 , the XR presenting unit  346 , and the data transmitting unit  348  are shown as residing on a single device (e.g., the electronic device  120 ), it should be understood that in other implementations, any combination of the data obtaining unit  342 , the task list unit  344 , the XR presenting unit  346 , and the data transmitting unit  348  may be located in separate computing devices. 
     Moreover,  FIG.  3    is intended more as a functional description of the various features that could be present in a particular implementation as opposed to a structural schematic of the implementations described herein. As recognized by those of ordinary skill in the art, items shown separately could be combined and some items could be separated. For example, some functional modules shown separately in  FIG.  3    could be implemented in a single module and the various functions of single functional blocks could be implemented by one or more functional blocks in various implementations. The actual number of modules and the division of particular functions and how features are allocated among them will vary from one implementation to another and, in some implementations, depends in part on the particular combination of hardware, software, and/or firmware chosen for a particular implementation.

In various implementations, certain objects (such as the real objects  411 - 416  and the virtual arrow  401 ) are displayed at a location in the XR environment  400 , e.g., at a location defined by three coordinates in a three-dimensional (3D) XR coordinate system. Accordingly, when the user moves in the XR environment  400  (e.g., changes either position and/or orientation), the objects are moved on the display of the device but retain their location in the XR environment  400 . In various implementations, certain virtual objects (such as the grocery list  420 ) are displayed at locations on the display such that when the user moves in the XR environment  400 , the objects are stationary on the display on the device.

     In FIG.  4 C 1 , the peas element  424  includes a line  431  through the peas element  424 . Thus, in FIG.  4 C 1 , the text of the peas element  424  is crossed out or struck through. 
     In FIG.  4 C 2 , the peas element  424  is displayed in a different color than in  FIG.  4 B . Thus, in FIG.  4 C 2 , the text of the peas element  424  is grayed out. 
     In FIG.  4 C 3 , the peas element  424  is displayed at a different location than in  FIG.  4 B . Thus, in FIG.  4 C 3 , the peas element  424  is moved to the bottom of the grocery list  420  in a “done” section. 
     In FIG.  4 C 4 , the peas element  424  is not displayed. Thus, in FIG.  4 C 4 , the peas element  424  is removed from the grocery list  420 .

       FIGS.  5 A- 5 C  illustrate an XR environment  500  based on a physical environment of a workstation.  FIGS.  5 A- 5 C  illustrate the XR environment  500  from the perspective of a user while the user completes one or more tasks. In various implementations, the perspective of the user is from a location of an image sensor of an electronic device. For example, in various implementations, the electronic device is a handheld electronic device and the perspective of the user is from a location of the image sensor of the handheld electronic device directed towards the physical environment. In various implementations, the perspective of the user is from the location of a user of the electronic device. For example, in various implementations, the electronic device is a head-mounted electronic device and the perspective of the user is from a location of the user directed towards the physical environment, generally approximating the field-of-view of the user were the head-mounted electronic device not present. In various implementations, the perspective of the user is from the location of an avatar of the user. For example, in various implementations, the XR environment  500  is a virtual environment and the perspective of the user is from location of an avatar or other representation of the user directed towards the virtual environment. 
       FIG.  5 A  illustrates the XR environment  500  at a first time. At the first time, the XR environment  500  includes a plurality of objects, including one or more real objects (e.g., a laptop  511  on a desk  512 ) and one or more virtual objects (e.g., a mailing list  520 ). 
     At the first time, the laptop  511  displays a cursor  545  within an e-mail user interface  540  including a to field  541 , a message field  542 , and a send button  543 . The mailing list  520  includes a plurality of elements  521 - 524  corresponding to a plurality of tasks.

     In various implementations, the mailing list  520  is displayed in response to a trigger event. For example, in various implementations, the mailing list  520  is displayed in response to a user request, which may be verbal request. In various implementations, the mailing list  520  is displayed in response to detecting the laptop  511  or the e-mail user interface  540  in the video stream. 
       FIG.  5 B  illustrates the XR environment  500  at a second time subsequent to the first time. At the second time, the user has entered “Bob” in the to field  541 , entered a message in the message field  542 , and moved the cursor  545  over the send button  543 . 
     In response to detecting that the user has entered “Bob” in the to field  541 , display of the Bob element  522  in the mailing list  520  is changed. In  FIG.  5 B , the Bob element  522  is displayed in bold with a slightly larger font size. In various implementations, in response to detecting that the user is interacting with an object associated with a corresponding task of the plurality of tasks (e.g., the laptop  511  with “Bob” entered in the to field  541  of the e-mail user interface  540 ), display of the corresponding element in the mailing list  520  is changed. 
       FIG.  5 C  illustrates the XR environment  500  at a third time subsequent to the second time. At the third time, the user has clicked the send button  543  sending an e-mail to Bob. Accordingly, at the third time, the to field  541  and the message field  542  of the e-mail user interface  540  are empty. 
     In response to detecting that the user has completed the task associated with the Bob element  522 , e.g., that the user has sent an e-mail to Bob, display of the Bob element  522  is changed. In various implementations, in response to detecting that the user has completed a task associated with an element, display of the element is changed in various ways. In  FIG.  5 C , the Bob element  522  includes a line  531  through the Bob element  522 . Thus, in  FIG.  5 C , the text of the Bob element  522  is crossed out or struck through. 
       FIG.  6    is a flowchart representation of a method  600  of displaying a task list in accordance with some implementations. In various implementations, the method  600  is performed by a device with an image sensor, one or more processors, and non-transitory memory (e.g., the electronic device  120  of  FIG.  3   ). In some implementations, the method  600  is performed by processing logic, including hardware, firmware, software, or a combination thereof. In some implementations, the method  600  is performed by a processor executing instructions (e.g., code) stored in a non-transitory computer-readable medium (e.g., a memory). 
     The method  600  begins, in block  610 , with the device obtaining, using the image sensor, a video stream of a physical environment. For example,  FIGS.  4 A- 4 K  illustrate a video stream of a physical environment of a grocery store from a perspective of a user while the user performs a plurality of tasks. As another example,  FIGS.  5 A- 5 C  illustrate a video stream of a physical environment of a workspace from a perspective of a user while the user sends an e-mail. 
     The method  600  continues, in block  620 , with the device displaying, on the display in association with the physical environment, a task list including a plurality of task elements respectively associated with a plurality of tasks, wherein the plurality of task elements includes a first task element associated with a first task and a second task element associated with a second task. For example,  FIG.  4 A  illustrates the grocery list  420  including a plurality of elements  421 - 426  respectively associated with a plurality of tasks (e.g., obtaining a plurality of groceries). As another example,  FIG.  5 A  illustrates the mailing list  520  including a plurality of elements  521 - 524  respectively associated with a plurality of tasks (e.g., sending e-mails to a plurality of recipients). 
     In various implementations, the display is an opaque display and the task list is displayed in association with the physical environment as a composite image of the task list and an image of the physical environment. Thus, in various implementations, displaying the task list includes displaying, based on the video stream of the physical environment, a video representation of the physical environment including the task list. In various implementations, the display is a transparent display and the task list is displayed in association with the physical environment as a projection over a view of the physical environment. 
     In various implementations, the method  600  includes detecting a trigger event and displaying the task list (in block  620 ) is performed in response to detecting the trigger event. In various implementations, the detecting the trigger event includes detecting a user request to display the task list, which may be a verbal request. In various implementations, detecting the trigger event includes detecting that the device is at a particular location. For example, in various implementations, the grocery list  420  of  FIG.  4 A  is displayed in response to detecting that the user is at a grocery store, e.g., using GPS or in response to detecting groceries in the video stream. In various implementations, detecting the trigger event includes detecting a particular object in the video stream of the physical environment. For example, in various implementations, the mailing list  520  of  FIG.  5 A  is displayed in response to detecting the laptop  511  or the e-mail user interface  540  in the video stream. 
     In various implementations, in response to determining that the trigger event is a first trigger event, displaying the task list includes displaying a first task list including a first plurality of task elements and wherein, in response to determining that the trigger event is a second trigger event, displaying the task list includes displaying a second task list including a second plurality of task elements different than the first plurality of task elements. For example, in various implementations, in response to detecting groceries in the video stream of the physical environment, the grocery list  420  of  FIG.  4 A  is displayed and, in response to detecting the laptop  511  in the video stream of the physical environment, the mailing list  520  of  FIG.  5 A  is displayed. 
     In various implementations, the plurality of tasks includes user interaction with a respective plurality of objects. For example, in  FIG.  4 A , the grocery list  420  includes a plurality of elements  421 - 426  respectively associated with a plurality of tasks of interacting with a respective plurality of groceries (e.g., taking the groceries off a shelf and placing the groceries in a basket). In various implementations, the plurality of tasks includes sending messages to a respective plurality of recipients. For example, in  FIG.  5 A , the mailing list  520  including a plurality of elements  521 - 524  respectively associated with a plurality of tasks of sending e-mails to a respective plurality of recipients. 
     In various implementations, the plurality of tasks includes tasks to be performed by a user of the electronic device, thereby forming a to-do list. In various implementations, the plurality of tasks includes tasks to be performed by one or more people other than the user of the device, such as employees of a user of the device, thereby forming a quality control list. 
     The method  600  continues, in block  630 , with the device detecting, in the video stream of the physical environment, completion of the first task. The method  600  continues, in block  640 , with the device, in response to detecting completion of the first task, changing display of the first task element. In various implementations, changing display of the first task element includes changing from displaying the first task element in a first manner to displaying the first task element in a second manner. 
     In various implementations, changing display of the first task element includes displaying a line through the first task element. For example, in FIG.  4 C 1 , the peas element  424  includes a line  431  through the peas element  424 . In various implementations, changing display of the first task element includes changing a color of the first task element. For example, in FIG.  4 C 2 , the peas element  424  is displayed in a different color than in  FIG.  4 B . In various implementations, changing display of the first task element includes moving the first task element in the task list. For example, in FIG.  4 C 3 , the peas element  424  is displayed at a different location than in  FIG.  4 B . In various implementations, changing display of the first task element includes removing the first task element from the task list. In various implementations, changing display of the first task element includes ceasing display of the first task element. For example, in FIG.  4 C 4 , the peas element  424  is not displayed. 
     In various implementations, the method  600  includes detecting, in the video stream of the physical environment, that the first task is in progress, and, in response to detecting that the first task is in progress, changing display of the first task element. For example, in  FIG.  4 B , in response to detecting that the user has picked up the peas  414 , display of the peas element  424  in the grocery list  420  is changed, e.g., the text is displayed in bold with a slightly larger font size. In various implementations, display of the first task element is changed in a first manner in response to detecting that the first task is in progress and display of the first task element is changed in a second manner in response to detecting completion of the first task. For example, in  FIG.  4 B , the peas element  424  is shown in bold and, in FIG.  4 C 1 , the peas element  424  includes the line  431 . 
     In various implementations, the method  600  includes detecting, in the video stream of the physical environment, that the second task is in progress and, in response to detecting that the second task is in progress, changing display of the second task element. For example, in  FIG.  4 D , in response to detecting that the user has picked up the premium carrots  412 , display of the carrots element  421  is changed. In various implementations, the method  600  includes detecting, in the video stream of the physical environment, that the second task is no longer in progress and is not completed and, in response to detecting that the second task is in progress, reverting display of the second task element. For example, in  FIG.  4 E , in response to detecting that the user has replaced the premium carrots  412 , display of the carrots element  421  is reverted. 
     In various implementations, the method  600  includes detecting a user input directed to the second task element and, in response to detecting the user input directed to the second task element, changing display of the second task element. For example, in  FIG.  4 H , the user performs a gesture directed to the bread element  423  and, in  FIG.  4 I , display of the bread element  423  includes the line  433 . 
     In various implementations, the method  600  includes detecting a user input directed to the task list and, in response to detecting the user input directed to the task list, ceasing display of the task list. For example, in  FIG.  4 J , the user performs a gesture directed to the grocery list  420  and, in  FIG.  4 K , the grocery list  420  is not displayed.

These terms are only used to distinguish one element from another. For example, a first node could be termed a second node, and, similarly, a second node could be termed a first node, which changing the meaning of the description, so long as all occurrences of the “first node” are renamed consistently and all occurrences of the “second node” are renamed consistently. The first node and the second node are both nodes, but they are not the same node. 
     The terminology used herein is for the purpose of describing particular implementations only and is not intended to be limiting of the claims. As used in the description of the implementations and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “comprises” and/or “comprising.” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     As used herein, the term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in accordance with a determination” or “in response to detecting,” that a stated condition precedent is true, depending on the context. Similarly, the phrase “if it is determined [that a stated condition precedent is true]” or “if [a stated condition precedent is true]” or “when [a stated condition precedent is true]” may be construed to mean “upon determining” or “in response to determining” or “in accordance with a determination” or “upon detecting” or “in response to detecting” that the stated condition precedent is true, depending on the context.
