TECHNICAL FIELD The following disclosure relates generally to wearable electronic devices, and more particularly to interfaces for wearable electronic devices.

Advanced personal electronic devices can have small form factors. These personal electronic devices may include, but are not limited to, tablets and smartphones. The use of such personal electronic devices involves manipulating user interface objects on display screens that also have a small form factor to complement the design of personal electronic devices.

Exemplary operations that a user may perform on the personal electronic device include navigating a hierarchy, selecting user interface objects, adjusting the position, size, and zoom of user interface objects, or Manipulating the user interface in other ways can be mentioned. Exemplary user interface objects include digital images, videos, text, icons, maps, control elements such as buttons, and other graphics. Users can perform such operations within software execution platforms such as image management software, video editing software, word processing software, operating system desktops, website browsing software, and other environments.

Existing methods for manipulating user interface objects on touch-sensitive displays of reduced size can be inefficient. Moreover, the accuracy provided by existing methods is generally not as high as desired.

The present disclosure relates to operating a user interface on a wearable electronic device using a mechanical crown. In some examples, the user interface may scroll or scale as the crown rotates. The direction of scrolling or scaling and the amount of scrolling or scaling can depend on the direction and amount of rotation of the crown, respectively. In some examples, the amount of scrolling or scaling can be proportional to the change in the rotation angle of the crown. In another example, the scroll speed or scaling speed can depend on the angular rotational speed of the crown. In these examples, greater rotation speeds can cause greater scrolling or scaling speeds to be performed on the displayed view.

In the following disclosure and description of examples, reference is made to the accompanying drawings in which specific examples that may be implemented are shown by way of illustration. It is to be understood that other examples may be implemented and structural changes may be made without departing from the scope of the present disclosure.

The present disclosure relates to operating a user interface on a wearable electronic device using a mechanical crown. In some examples, the user interface may scroll or scale as the crown rotates. The direction of scrolling or scaling and the amount of scrolling or scaling can depend on the direction and amount of rotation of the crown, respectively. In some examples, the amount of scrolling or scaling can be proportional to the change in the rotation angle of the crown. In another example, the scroll speed or scaling speed can depend on the angular rotational speed of the crown. In these examples, greater rotation speeds can cause greater scrolling or scaling speeds to be performed on the displayed view.

FIG. 1 shows an exemplary personal electronic device 100 . In the illustrated example, the device 100 is a watch generally including a body 102 and a strap 104 for attaching the device 100 to the user's body. That is, device 100 is wearable. Body 102 can be designed to mate with strap 104 . Device 100 may have a touch-sensitive display screen (hereinafter touchscreen) 106 and a crown 108 . Device 100 may also have buttons 110 , 112 , and 114 .

Conventionally, the term "crown" in the context of watches refers to the cap on the mandrel for winding the watch. In the context of personal electronic devices, the crown can be a physical component of the electronic device rather than a virtual crown on a touch-sensitive display. The crown 108 can be mechanical. That is, it can be connected to a sensor for converting the physical movement of the crown into an electrical signal. The crown 108 can rotate in two rotational directions (eg, forward and backward). Crown 108 can also be pushed toward the body of device 100 and/or pulled away from device 100 . Crown 108 can be touch sensitive, for example, using capacitive touch technology that can detect whether a user is touching the crown. Still further, the crown 108 can also be pivoted in one or more directions or translated along a trajectory along an edge or at least partially around the circumference of the body 102 . In some examples, more than one crown 108 can be used. The visual appearance of the crown 108 can resemble that of a conventional watch, but need not. Buttons 110, 112, and 114, if included, can each be physical buttons or touch-sensitive buttons. That is, the buttons may be physical buttons or capacitive buttons, for example. Additionally, the body 102, which may include a bezel, may have predetermined areas on the bezel that serve as buttons.

Display 106 is a touch sensor panel implemented using any desired touch sensing technology, such as mutual capacitive touch sensing, self-capacitive touch sensing, resistive touch sensing, projected scanning touch sensing, or the like. liquid crystal display (LCD), light-emitting diode (LED) display, organic light-emitting diode (OLED) display, or A display device, such as the like, can be included. The display 106 can allow the user to hover near and touch on the touch sensor panel with one or more fingers or other objects to perform various functions. .

In some examples, device 100 can further include one or more pressure sensors (not shown) to detect the amount of force or pressure applied to the display. The amount of force or pressure applied to display 106 may be any desired, such as making a selection, entering or exiting a menu, causing display of additional options/actions, or the like. can be used as an input to device 100 to perform the operations of In some examples, different actions can be performed based on the amount of force or pressure being applied to display 106 . One or more pressure sensors can also be used to determine the position at which force is being applied to display 106 .

FIG. 2 shows a block diagram of some of the components of device 100 . As shown, crown 108 may be coupled to encoder 204 . The encoder 204 monitors the physical state of the crown 108 or a change in physical state (eg, the position of the crown) and converts it into an electrical signal (eg, converts it to the position of the crown 108 or the change in position). to an analog or digital signal representation) and provide the signal to processor 202 . For example, in some examples, encoder 204 may be configured to sense the absolute rotational position of crown 108 (eg, an angle of 0-360°) and output an analog or digital representation of this position to processor 202. can be done. Alternatively, in another example, encoder 204 senses changes in the rotational position of crown 108 (eg, changes in rotational angle) over some sampling period and provides an analog or digital representation of the sensed changes to processor 202. can be configured to output In these examples, the crown position information may further indicate the direction of rotation of the crown (eg, positive values may correspond to one direction and negative values may correspond to the other). In still other examples, encoder 204 can be configured to detect rotation of crown 108 in any desired manner (e.g., velocity, acceleration, or the like) and pass crown rotation information to processor 202. can provide. Rotation speed can be expressed in a number of ways. For example, the rotation speed is hertz, rotation per unit time (rotation), rotation per frame (rotation), rotation per unit time (revolution), rotation per frame (revolution), It can be expressed in direction and speed of rotation, such as change in angle per unit time, and the like. Alternatively, instead of providing information to processor 202 , this information may be provided to other components of device 100 . Although the examples described herein refer to utilizing the rotational position of the crown 108 to control scrolling or scaling of the view, using any other physical state of the crown 108 is also possible. It should be understood that

In some examples, the physical state of the crown can control physical attributes of display 106 . For example, the ability of display 106 to traverse the z-axis can be limited when crown 108 is in a particular position (eg, rotated forward). In other words, the physical state of the crown can represent the physical modal functionality of display 106 . In some examples, temporal attributes of the physical state of crown 108 can be used as input to device 100 . For example, fast changes in physical state can be interpreted differently than slow changes in physical state.

Processor 202 can be further coupled to receive input signals from buttons 110 , 112 , and 114 along with touch signals from touch-sensitive display 106 . Processor 202 may be configured to interpret these input signals and output appropriate display signals for generating images by touch-sensitive display 106 . Although a single processor 202 is shown, it should be appreciated that any number of processors or other computing devices may be used to perform the general functions described above.

FIG. 3 illustrates an illustrative process 300 for scrolling through a displayed set of applications using a crown, according to various examples. In some examples, process 300 can be performed by a wearable electronic device similar to device 100 . In these examples, visual representations (e.g., icons, graphical images, text images, and the like) of one or more applications in the set of applications can be displayed on the display 106 of the device 100, and the crown Process 300 can be performed to visually scroll through the set of applications by sequentially displaying the applications as the rotation of 108 . In some examples, scrolling can be performed by translating displayed content along a fixed axis.

At block 302, crown position information may be received. In some examples, crown position information may include an analog or digital representation of the absolute position of the crown, such as an angle between 0 and 360 degrees. In other examples, crown position information may include analog or digital representations of changes in the rotational position of the crown, such as changes in rotational angle. For example, an encoder similar to encoder 204 can be coupled to a crown similar to crown 108 to monitor and measure its position. The encoder can convert the position of crown 108 into crown position information that can be transmitted to a processor similar to processor 202 .

At block 304, it may be determined whether a change in position has been detected. In some examples, if the crown position information includes an absolute position of the crown, determining whether a change in position has occurred may be performed by comparing the position of the crown at two different time instances. can be done. For example, the processor (e.g., processor 202) may determine the most recent position of the crown (e.g., crown 108) as indicated by the crown position information to the front of the crown as indicated by the previously received crown position information. can be compared to the (e.g., immediately preceding) position of . If the positions are the same or are within a threshold value (eg, a value corresponding to the encoder tolerance), then it can be determined that no change in position has occurred. However, if the positions are not the same, or differ by at least a threshold value, then it can be determined that a change in position has occurred. In another example, if the crown position information includes a change in position over some amount of time, determining whether a change in position has occurred is determined by whether the absolute value of the change in position is equal to zero. , or is less than a threshold (eg, a value corresponding to the encoder tolerance). If the absolute value of the change in position is equal to 0 or less than a threshold, it can be determined that no change in position has occurred. However, if the absolute value of the change in position is 0 or greater than the threshold, it can be determined that a change in position has occurred.

If it is determined at block 304 that no change in crown position has been detected, the process may return to block 302 where new crown position information may be received. Alternatively, however, if at block 304 it is determined that a change in crown position has been detected, the process may proceed to block 306 . A positive determination at block 304 may cause the process to proceed to block 306, while a negative determination may cause the process to return to block 302, as described herein. However, the determination made at block 304 can be reversed such that a positive determination can cause the process to return to block 302 while a negative determination can cause the process to proceed to block 306 . It should be understood that For example, block 304 can alternatively determine whether a change in position has not been detected.

At block 306, at least a portion of the set of applications may be scrolled based on the detected change in location. A set of applications can include any ordered or unordered set of applications. For example, the set of applications may include all applications stored on the wearable electronic device, all open applications on the wearable electronic device, a user-selected set of applications, or the like. Additionally, applications can be ordered based on frequency of use, user-defined ordering, relevance, or any other desired ordering.

In some examples, block 306 may include visually scrolling through the set of applications by sequentially displaying the applications in response to changes in the detected position of the crown. For example, a display (eg, display 106) may be displaying one or more applications of a set of applications. In response to detecting a change in the position of the crown (eg, crown 108), one or more currently displayed applications are translated out of the display and one or more other applications are translated onto the display. Make room for it to be moved. In some examples, the one or more other applications that are translated onto the display are displayed based on their relative ordering within the set of applications corresponding to the direction opposite the direction of translation. can be selected for The direction of translation can depend on the direction of change in crown position. For example, rotating the crown clockwise can cause scrolling of the display in one direction, while rotating the crown counterclockwise can cause the display to scroll in a second (e.g., opposite) direction. Scrolling can occur. Additionally, the scroll distance or speed may depend on the amount of detected change in crown position. Scroll distance can refer to the distance on the screen that content is scrolled. Scrolling speed can refer to the distance that content is scrolled over a period of time. In some examples, the scrolling distance or speed can be proportional to the amount of rotation detected. For example, the amount of scrolling corresponding to one half rotation of the crown can be equal to 50% of the amount of scrolling corresponding to one rotation of the crown. In some examples where the set of applications includes an ordered list of applications, scrolling may stop upon reaching the end of the list. In another example, scrolling can continue by looping around to the opposite end of the list of applications. The process can then return to block 302, where new crown position information can be received.

It should be understood that the actual values used to linearly correspond changes in crown position to scrolling distance or speed may vary depending on the desired functionality of the device. Further, it should be understood that other correspondences between scrolling amount or speed and changes in crown position can be used. For example, acceleration, velocity (discussed in more detail below with respect to FIGS. 21-44), or the like can be used to determine scroll distance or speed. Additionally, a non-linear mapping between crown characteristics (eg, position, velocity, acceleration, etc.) and scroll amount or scroll speed can be used.

To further illustrate the operation of process 300, FIG. 4 has portions of visual representations of application 406 (e.g., icons, graphical images, text images, and the like) and visual representations of applications 404 and 408. An exemplary interface of device 100 is shown. Applications 404, 406, and 408 can be any number of ordered or unordered applications (eg, all applications on device 100, all open applications on device 100, user favorites, or (similar ones) can be part of a set of applications containing any group of At block 302 of process 300 , processor 202 of device 100 may receive crown position information from encoder 204 . Since crown 108 is not rotated in FIG. 4, a negative determination may be made by processor 202 at block 304, causing the process to return to block 302.

Referring now to FIG. 5, crown 108 has been rotated upward as indicated by direction of rotation 502 . Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 302 of process 300 . Therefore, processor 202 may make an affirmative determination at block 304 , which causes the process to proceed to block 306 . At block 306 , processor 202 may cause display 106 to scroll through at least a portion of the set of applications on device 100 . The scrolling can have a scrolling direction 504 that corresponds to the rotational direction 502 of the crown 108 and a scrolling amount or speed based on the characteristics of the rotation of the crown 108 (eg, distance, speed, acceleration, or the like). In the illustrated example, the scroll distance can be proportional to the amount of rotation of crown 108 . As shown, the display 106 can scroll through the set of applications by translating the visual representation of the applications in the scroll direction 504 . As a result, application 408 is completely kicked off display 106 , application 406 is partially kicked off display 106 , and application 404 is displayed on display 106 with a larger portion. As the user continues to rotate crown 108 in rotational direction 502, processor 202 can cause display 106 to continue scrolling the view of the set of applications in scrolling direction 504, as shown in FIG. In FIG. 6, application 406 is barely visible on the right side of display 106 , application 404 is centered within display 106 , and newly displayed application 402 is displayed on the left side of display 106 . In this example, application 402 may be another application in the set of applications and may have an ordered position to the left or in front of application 404 . In some examples, if application 402 is the first application in the list of applications and the user continues to rotate crown 108 in rotational direction 502, processor 202 may cause application 402 to be centered within the display. Scrolling of the display 106 can be restricted to stop scrolling when prompted. Alternatively, in another example, processor 202 continues scrolling display 106 by looping to the end of the set of applications, moving the last application in the set of applications (eg, application 408 ) to the left of application 402 . can be displayed.

Referring now to FIG. 7, crown 108 has been rotated in downward rotational direction 506 . Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 302 of process 300 . Therefore, processor 202 may make an affirmative determination at block 304 , which causes the process to proceed to block 306 . At block 306 , processor 202 may cause display 106 to scroll the view of the application in scroll direction 508 that corresponds to rotation direction 506 . In this example, scroll direction 508 is opposite scroll direction 504 . However, it should be appreciated that the scroll direction 508 can be in any desired direction. Similar to scrolling performed in response to rotation of crown 108 in rotational direction 502, scrolling performed in response to rotation of crown 108 in rotational direction 506 depends on the characteristics of the rotation of crown 108 (e.g., distance, velocity, acceleration, , or similar). In the illustrated example, the scroll distance can be proportional to the amount of rotation of crown 108 . As shown, the display 106 can scroll through the set of applications by translating the visual representation of the applications in the scroll direction 508 . As a result, application 402 is completely kicked off display 106 , application 404 is partially kicked off display 106 , and application 406 is shown on display 106 with a larger portion. As the user continues to rotate the crown 108 in the rotational direction 506, the processor 202 can cause the display 106 to continue scrolling the view of the set of applications in the scrolling direction 508, as shown in FIG. In FIG. 8, application 404 is barely visible on the left side of display 106 , application 406 is centered within display 106 , and application 408 is again displayed on the right side of display 106 . In some examples, if application 408 is the last application in the list of applications and the user continues to rotate crown 108 in rotational direction 508, processor 202 will cause application 408 to be centered within the display. , the scrolling of the display 106 can be restricted to stop scrolling. Alternatively, in another example, processor 202 continues scrolling display 106 by looping to the beginning of the set of applications, moving the first application in the set of applications (eg, application 402 ) to the right of application 408 . can be displayed.

Although specific scrolling examples are provided, it should be understood that the mechanical crown of the wearable electronic device can be used in a similar manner to similarly scroll other displays of applications. Additionally, the scroll distance or speed can be configured to depend on any characteristic of the crown.

FIG. 9 shows an illustrative process 900 for scrolling a view of a display using a crown, according to various examples. A view can include a visual representation of any kind of data that is displayed. For example, views can include displays of text, media items, web pages, maps, or the like. Process 900 can be similar to process 300, except that process 900 can be more generally applied to any kind of content or view displayed on a device's display. In some examples, process 900 can be performed by a wearable electronic device similar to device 100 . In these examples, content or any other view can be displayed on display 106 of device 100 and process 900 is performed to visually scroll the view in response to rotation of crown 108. can be done. In some examples, scrolling can be performed by translating displayed content along a fixed axis.

At block 902, crown position information may be received in a manner similar or identical to that described above with respect to block 302. For example, crown position information can be received from an encoder (eg, encoder 204) by a processor (eg, processor 202) and can be used to determine the absolute position of the crown, changes in rotational position of the crown, or other positional information of the crown. It can include analog or digital representations.

At block 904 , it may be determined whether a change in position has been detected in a manner similar or identical to that described above with respect to block 304 . For example, block 904 may include comparing the crown position at two different time instances, or determining whether the absolute value of the change in crown position is equal to 0 or below a threshold value. can include If no position change was detected, the process may return to block 902 . Alternatively, the process can proceed to block 906 if a change in position has been detected. A positive determination at block 904 may cause the process to proceed to block 906, while a negative determination may cause the process to return to block 902, as described herein. However, the determination made at block 904 can be reversed such that a positive determination can cause the process to return to block 902, while a negative determination can cause the process to proceed to block 906. It should be understood that For example, block 904 can alternatively determine whether a change in position has not been detected.

At block 906, the display view may be scrolled based on the detected change in position. Similar to block 306 of process 300, block 906 can include visually scrolling the view by translating the view of the display in response to changes in the detected position of the crown. For example, a display (eg, display 106) may be displaying a portion of some content. In response to detecting a change in the position of the crown (eg, crown 108), the currently displayed portion of the content is translated out of the display for other portions of the content that were not previously displayed. can vacate a place for The direction of translation can depend on the direction of change in crown position. For example, rotating the crown clockwise can cause scrolling of the display in one direction, while rotating the crown counterclockwise can cause the display to scroll in a second (e.g., opposite) direction. Scrolling can occur. Additionally, the scroll distance or speed may depend on the amount of detected change in crown position. In some examples, the scrolling distance or speed can be proportional to the amount of rotation detected. For example, the amount of scrolling corresponding to one half rotation of the crown can be equal to 50% of the amount of scrolling corresponding to one rotation of the crown. The process can then return to block 902, where new crown position information can be received.

It should be understood that the actual values used to linearly correspond changes in crown position to scrolling distance or speed may vary depending on the desired functionality of the device. Furthermore, it should be appreciated that other mappings between scroll amount and position change can be used. For example, acceleration, velocity (discussed in more detail below with respect to FIGS. 21-44), or the like can be used to determine scroll distance or speed. Additionally, a non-linear mapping between crown characteristics (eg, position, velocity, acceleration, etc.) and scroll amount or scroll speed can be used.

To further explain the operation of process 900, FIG. 10 shows an exemplary interface of device 100 with a visual representation of lines of text containing the numbers 1-9. At block 902 of process 900 , processor 202 of device 100 may receive crown position information from encoder 204 . Since the crown 108 is not rotated in FIG. 10, a negative determination may be made by the processor 202 at block 904 which causes the process to return to block 902 .

Referring now to FIG. 11, crown 108 has been rotated in upward rotational direction 1102 . Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 902 of process 900 . Therefore, processor 202 may make an affirmative determination at block 904 , which causes the process to proceed to block 906 . At block 906 , processor 202 may cause display 106 to scroll the lines of text displayed on display 106 . The scroll can have a scroll direction 1104 that corresponds to the direction of rotation 1102 of the crown 108 and a scroll amount or speed based on the characteristics of the rotation of the crown 108 (eg, distance, speed, acceleration, or the like). In the illustrated example, the scroll distance can be proportional to the amount of rotation of crown 108 . As shown, display 106 can scroll lines of text by translating the text in scroll direction 1104 . As a result, a portion of row 1002 is ejected from display 106 while a portion of row 1004 is newly displayed on the bottom of display 106 . The lines of text between lines 1002 and 1004 have been similarly translated in scroll direction 1104 . As the user continues to rotate crown 108 in rotational direction 1102, processor 202 can cause display 106 to continue scrolling lines of text in scrolling direction 1104, as shown in FIG. In FIG. 12, row 1002 is no longer visible in display 106 and row 1004 is now completely within view of display 106 . In some examples, if line 1004 is the last line of text and the user continues to rotate crown 108 in rotational direction 1102 , processor 202 determines that line 1004 is displayed completely within display 106 . , the scrolling of the display 106 can be restricted to stop scrolling. In another example, processor 202 may continue scrolling display 106 by looping to the beginning of the line of text, causing the first line of text (eg, line 1002 ) to be displayed below line 1004 . In yet another example, displaying a margin below the line 1004, flipping back the line of text in response to the crown 108 stopping rotation, and performing a rubber banding effect by aligning the line 1004 with the bottom of the display 106. can be done. It should be appreciated that the action taken in response to reaching the edge of the content displayed within display 106 may be selected based on the type of data being displayed.

Referring now to FIG. 13, crown 108 has been rotated in downward rotational direction 1106 . Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 902 of process 900 . Therefore, processor 202 may make an affirmative determination at block 904 , which causes the process to proceed to block 906 . At block 906 , processor 202 may cause display 106 to scroll lines of text in scroll direction 1108 corresponding to rotation direction 1106 . In this example, scroll direction 1108 is opposite scroll direction 1104 . However, it should be appreciated that the scroll direction 1108 can be in any desired direction. Similar to scrolling performed in response to rotation of crown 108 in direction of rotation 1102, scrolling performed in response to rotation of crown 108 in direction of rotation 1106 depends on the characteristics of rotation of crown 108 (e.g., distance, velocity, acceleration, etc.). , or similar). In the illustrated example, the scroll distance can be proportional to the amount of rotation of crown 108 . As shown, display 106 can scroll lines of text by translating the lines of text in scroll direction 1108 . As a result, a portion of row 1004 can be ejected from display 106 while a portion of row 1002 can be redisplayed on top of display 106 . As the user continues to rotate crown 108 in rotational direction 1106, processor 202 can cause display 106 to continue scrolling lines of text in scrolling direction 1108, as shown in FIG. As shown in FIG. 14, row 1004 has been translated out of display 106, while row 1002 is now fully visible. In some examples, if line 1002 is the first line of text and the user continues to rotate crown 108 in rotational direction 1106 , processor 202 will cause line 1002 to scroll to the top of display 106 . Scrolling of the display 106 can be restricted so as to stop the In another example, processor 202 may continue scrolling display 106 by looping to the end of the line of text, causing the last line of text (eg, line 1004 ) to be displayed above line 1002 . In yet another example, displaying a margin above the line 1002, flipping back the line of text upon stopping rotation of the crown 108, and performing a rubber banding effect by aligning the line 1002 with the top of the display 106. can be done. It should be appreciated that the action taken in response to reaching the edge of the content displayed within display 106 may be selected based on the type of data being displayed.

Although specific scrolling examples are provided, the mechanical crown of the wearable electronic device can be used in a similar manner to similarly scroll other types of data, such as media items, web pages, or the like. It should be understood that Additionally, the scroll distance or speed can be configured to depend on any characteristic of the crown.

FIG. 15 shows an illustrative process 1500 for scaling (eg, zooming in or out) a view of a display using a crown, according to various examples. A view can include a visual representation of any kind of data that is displayed. For example, views can include displays of text, media items, web pages, maps, or the like. Process 1500 is similar to processes 300 and 900, except that instead of scrolling between applications or scrolling the view of the device, the view can be scaled positively or negatively depending on the rotation of the crown. can be similar. In some examples, process 1500 can be performed by a wearable electronic device similar to device 100 . In these examples, content or any other view can be displayed on display 106 of device 100 and process 1500 is performed to visually scale the view in response to rotation of crown 108. can be done.

At block 1502, crown position information may be received in a manner similar or identical to that described above with respect to blocks 302 or 902. For example, crown position information can be received from an encoder (eg, encoder 204) by a processor (eg, processor 202) and can be used to determine the absolute position of the crown, changes in rotational position of the crown, or other positional information of the crown. It can include analog or digital representations.

At block 1504, it may be determined whether a change in position has been detected in a manner similar or identical to that described above with respect to blocks 304 or 904. FIG. For example, block 1504 may include comparing the crown position at two different time instances, or determining whether the absolute value of the change in crown position is equal to 0 or below a threshold value. can include If no position change was detected, the process may return to block 1502 . Alternatively, the process can proceed to block 1506 if a change in position is detected. A positive determination at block 1504 may cause the process to proceed to block 1506, while a negative determination may cause the process to return to block 1502, as described herein. However, the determination made at block 1504 can be reversed such that a positive determination can cause the process to return to block 1502, while a negative determination can cause the process to proceed to block 1506. It should be understood that For example, block 1504 can alternatively determine whether a change in position has not been detected.

At block 1506, the display view may be scaled based on the detected change in position. Block 1506 may include visually scaling the view (eg, zoom in/out) in response to the detected change in crown position. For example, a display (eg, display 106) may be displaying a portion of some content. In response to detecting a change in the position of the crown (e.g., crown 108), by increasing or decreasing the size of the currently displayed portion of the content in the view, depending on the direction of change in the position of the crown. , the view can be scaled. For example, turning the crown clockwise may increase the size of content within the display's view (e.g., zoom in), while turning the crown counterclockwise may increase the size of the content within the display's view. You can decrease the size (eg zoom out). Additionally, the amount or speed of scaling may depend on the amount of detected change in crown position. In some examples, the amount or speed of scaling may be proportional to the amount of detected rotation of the crown. For example, the scaling amount corresponding to half a crown rotation can be equal to 50% of the scaling amount corresponding to one crown rotation. The process can then return to block 1502, where new crown position information can be received.

It should be understood that the actual values used to linearly correspond changes in crown position to the amount or speed of scaling may vary depending on the desired functionality of the device. Furthermore, it should be appreciated that other mappings between scaling amounts and changes in position can be used. For example, acceleration, velocity (discussed in more detail below with respect to FIGS. 21-44), or the like can be used to determine the amount or speed of scaling. Additionally, a non-linear correspondence between crown characteristics (eg, position, velocity, acceleration, etc.) and scaling amount or scaling speed can be used.

To further explain the operation of process 1500 , FIG. 16 shows an exemplary interface of device 100 showing triangle 1602 . At block 1502 of process 1500 , processor 202 of device 100 may receive crown position information from encoder 204 . Since the crown 108 has not been rotated in FIG. 16, a negative determination can be made by the processor 202 at block 1504 , causing the process to return to block 1502 .

Referring now to FIG. 17, crown 108 has been rotated in upward rotational direction 1702 . Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 1502 of process 1500 . Therefore, processor 202 may make an affirmative determination at block 1504 , causing the process to proceed to block 1506 . At block 1506 , processor 202 may cause display 106 to scale the view displayed on display 106 . Scaling can increase or decrease the size of the view depending on the direction of rotation of the crown 108, scaling amount or speed based on the characteristics of the rotation of the crown 108 (e.g., distance, speed, acceleration, or the like). can have In the illustrated example, the amount of scaling may be proportional to the amount of rotation of crown 108 . As shown, display 106 can scale the view encompassing triangle 1602 using a positive scale factor. As a result, triangle 1602 in FIG. 17 appears larger than that shown in FIG. As the user continues to rotate crown 108 in rotational direction 1702, processor 202 causes display 106 to continue to scale the view containing the image of triangle 1602 using a positive scale factor, as shown in FIG. can be done. In FIG. 18, triangle 1602 appears larger than shown in FIGS. When the rotation of the crown 108 stops, the scaling of the view containing the triangle 1602 can stop as well. In some examples, if the view of triangle 1602 is scaled to its maximum amount and the user continues to rotate crown 108 in rotational direction 1702, processor 202 can limit the scaling of display 106 . In yet another example, the size of the view containing triangle 1602 is allowed to increase up to a rubberbanding limit that is greater than the maximum scaling amount for the view, and then the view's size in response to stopping rotation of crown 108. Rubberbanding effects can be performed by flipping the size back to its maximum scaling amount. It should be appreciated that the action taken in response to reaching the scaling limit of display 106 can be configured in any desired manner.

Referring now to FIG. 19, crown 108 has been rotated in downward rotational direction 1704 . Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 1502 of process 1500 . Therefore, processor 202 may make an affirmative determination at block 1504 , causing the process to proceed to block 1506 . At block 1506 , processor 202 may cause display 106 to scale the view using a negative scale factor corresponding to rotation direction 1704 . Similar to scaling performed in response to rotation of crown 108 in rotational direction 1702, scaling performed in response to rotation of crown 108 in rotational direction 1704 may be performed based on characteristics of the rotation of crown 108 (e.g., distance, velocity, acceleration, , or similar). In the illustrated example, the amount of scaling may be proportional to the amount of rotation of crown 108 . As shown, display 106 can scale the view containing the image of triangle 1602 using a negative scale factor. As a result, triangle 1602 in FIG. 19 is smaller than that shown in FIG. As the user continues to rotate crown 108 in rotational direction 1704, processor 202 causes display 106 to continue to scale the view of the image encompassing triangle 1602 using a negative scale factor, as shown in FIG. can be done. In FIG. 20, triangle 1602 is smaller than that shown in FIGS. When the rotation of the crown 108 stops, the scaling of the view containing the triangle 1602 can stop as well. In some examples, processor 202 may limit the scaling of display 106 if the view encompassing triangle 1602 is scaled to its minimum amount and the user continues to rotate crown 108 in rotational direction 1704. . In yet another example, the size of the view encompassing triangle 1602 is allowed to decrease to a rubberbanding limit that is less than the minimum scaling amount for the view, and then the view's size in response to stopping crown 108 rotation. Rubberbanding effects can be performed by flipping the size back to its minimum scaling amount. It should be appreciated that the action taken in response to reaching the scaling limit of display 106 can be configured in any desired manner.

Although specific scaling examples are provided, the wearable electronic device's mechanical crown can be used in a similar manner to provide views of other types of data, such as media items, web pages, or the like, as well. It should be appreciated that it can be scaled. Additionally, the amount or speed of scaling can be configured to depend on any characteristic of the crown. Further, in some examples, once the minimum or maximum scaling of the view is reached, continuing to rotate the crown in the same direction can cause scaling in the opposite direction. For example, upward rotation of the crown can cause the view to zoom in. However, once the scaling limit is reached, upward rotation of the crown can then cause the view to scale in the opposite direction (eg, zoom out).

FIG. 21 shows an illustrative process 2100 for scrolling a view of a display based on the angular rotational speed of the crown, in accordance with various examples. A view can include a visual representation of any kind of data that is displayed. For example, views can include presentations of text, media items, web pages, or the like. Process 2100 can be similar to process 900, except that process 2100 can scroll the view based on a scroll speed that depends on the angular rotational speed of the crown. In some examples, process 2100 can be performed by a wearable electronic device similar to device 100 . In these examples, content or any other view can be displayed on display 106 of device 100 and process 2100 is performed to visually scroll the view in response to rotation of crown 108. can be done. In some examples, scrolling can be performed by translating displayed content along a fixed axis.

At block 2102, a view of the wearable electronic device's display may be displayed. As mentioned above, a view can include any visual representation of any type of data displayed by the device's display.

At block 2104 , crown position information may be received in a manner similar or identical to that described above with respect to block 902 of process 900 . For example, crown position information can be received from an encoder (eg, encoder 204) by a processor (eg, processor 202) and can be used to determine the absolute position of the crown, changes in rotational position of the crown, or other positional information of the crown. It can include analog or digital representations.

At block 2106, a scroll speed (eg, speed and scroll direction) may be determined. In some examples, view scrolling can be determined using physics-based motion modeling. For example, a view can be treated as an object with a movement speed corresponding to the speed of scrolling across the device's display. Rotation of the crown can be treated as a force applied to the view in a direction corresponding to the direction of rotation of the crown. Here, the amount of force depends on the angular rotation speed of the crown. For example, a greater angular rotation speed can correspond to a greater amount of force applied to the view. Any desired linear or non-linear correspondence between the angular rotational speed of the crown and the force applied to the view can be used. Additionally, drag can be applied in a direction opposite to the scrolling direction. This can be used to decay the scrolling speed over time, allowing scrolling to stop without additional input from the user. Therefore, the scroll speed at discrete times can take the general form:

In Equation 1.1, V _T represents the determined scroll velocity (speed and direction) at time T, and V _(T-1) represents the previous scroll velocity (speed and direction) at time T-1. , ΔV _CROWN represents the change in velocity caused by the force applied to the view in response to the rotation of the crown, and ΔV _DRAG represents the change in velocity of the view caused by the drag force in the opposite direction to the motion of the view (scrolling of the view). . As mentioned above, the force exerted by the crown on the view can depend on the angular rotational speed of the crown. Therefore, ΔV _CROWN can also depend on the angular rotational speed of the crown. Generally, the greater the angular rotational speed of the crown, the greater the value of ΔV _CROWN . However, the actual mapping between crown angular rotation speed and ΔV _CROWN can vary depending on the desired user feel of the scroll effect. For example, various linear or non-linear mappings between crown angular rotational speed and ΔV _CROWN can be used. In some examples, ΔV _DRAG can be dependent on scroll speed, such that higher speeds can produce larger opposite velocity changes. In other examples, ΔV _DRAG can have a constant value. However, it should be understood that any constant or variable amount of opposite velocity change may be used to produce the desired scrolling effect. Typically, in the absence of user input in the form of ΔV _CROWN , V _T will approach (and go to) 0 based on ΔV _DRAG according to Equation 1.1, whereas crown rotation (ΔV _CROWN ), _VT will not change sign.

As can be seen from Equation 1.1, scroll speed can continue to increase as long as ΔV _CROWN is greater than ΔV _DRAG . Additionally, the scroll rate can have a non-zero value even when no input for ΔV _CROWN has been received. Therefore, if the view is scrolling at a non-zero speed, it can continue to scroll even if the user does not rotate the crown. The scrolling distance and time until scrolling stops can depend on the scrolling speed when the user stops rotating the crown, and the ΔV _DRAG component.

In some examples, the V _(T−1) component can be reset to a value of 0 when the crown is rotated in a direction corresponding to a scrolling direction that is opposite to the direction in which the view is currently being scrolled. , allows the user to quickly change the direction of scrolling without having to provide enough force to offset the current scrolling speed of the view.

At block 2108 , the display may be updated based on the scroll speed and direction determined at block 2106 . This may include translating the displayed view in a direction corresponding to the determined scroll direction by an amount corresponding to the determined scroll speed. The process can then return to block 2104, where additional crown position information can be received.

It should be appreciated that blocks 2104, 2106, and 2108 can be repeatedly executed at any desired frequency to continuously determine the scroll speed and update the display accordingly.

To further explain the operation of process 2100, FIG. 22 shows an exemplary interface of device 100 with a visual representation of lines of text containing the numbers 1-9. At block 2102 of process 2100, processor 202 of device 100 may cause display 106 to display the illustrated interface. At block 2104 , processor 202 may receive crown position information from encoder 204 . At block 2106, the scroll speed and scroll direction may be determined. Since the current scroll speed is 0 and the crown 108 is not currently being rotated, using equation 1.1 it can be determined that the new scroll speed is 0. At block 2108 , processor 202 may cause display 106 to update the display with the speed and direction determined at block 2106 . However, since the velocity determined was 0, no changes need to be made to the display. For illustrative purposes, FIGS. 23-29 show subsequent views of the interface shown in FIG. 22 at different times. Here the length of time between each view is equal.

Referring now to FIG. 23, crown 108 is being rotated in an upward rotational direction at rotational speed 2302 . Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 2104 . Therefore, at block 2106, processor 202 can convert this rotational speed to a value of ΔV _CROWN to determine a new scroll speed V _T . In this example, rotation of crown 108 in an upward direction corresponds to an upward scrolling direction. In other examples, other orientations can be used. At block 2108, processor 202 may cause display 106 to update the display based on the determined scroll speed and direction. As shown in FIG. 23, this update causes the line of text to translate upward at scroll speed 2304 . Since the crown 108 has just started to rotate, the rotation speed 2302 can be relatively low compared to the typical rotation speed of the crown. Therefore, the scroll speed 2304 can also have relatively low values compared to typical or maximum scroll speeds. As a result, only the portion of the line of text containing the value "1" has been translated out of the display.

Referring now to FIG. 24, crown 108 is rotated in an upward rotational direction at rotational speed 2306 , which can be greater than rotational speed 2302 . Processor 202 may again receive crown position information from encoder 204 at block 2104 . Therefore, at block 2106, processor 202 can convert this rotational speed to a value of ΔV _CROWN to determine a new scroll speed V _T . Since the display previously had a non-zero scroll speed value (eg, as shown in FIG. 23), the new ΔV _CROWN value corresponding to rotation speed 2306 is replaced by the previous scroll speed value V _(T−1) ( for example, with scroll speed 2304). Therefore, new scroll speed 2308 can be greater than scroll speed 2304 as long as the new value of ΔV _CROWN is greater than the value of ΔV _DRAG . However, new scroll speed 2308 can be less than scroll speed 2304 if the value of ΔV _CROWN corresponding to rotational speed 2306 is less than the value of ΔV _DRAG . In the illustrated example, it is assumed that the new ΔV _CROWN value is greater than the ΔV _DRAG value. At block 2108, processor 202 may cause display 106 to update the display based on the determined scroll speed and direction. As shown in FIG. 24, this update causes the line of text to translate upward at scroll speed 2308 . Scroll speed 2308 can be greater than scroll speed 2304 because the value of ΔV _CROWN corresponding to rotational speed 2306 is greater than the value of ΔV _DRAG . As a result, the line of text has been translated a greater distance over the same amount of time, such that a full line of text has been vertically translated out of the display.

Referring now to FIG. 25, the crown 108 is being rotated in an upward rotational direction at a rotational speed 2310 that can be greater than the rotational speed 2306 . Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 2104 . Therefore, at block 2106, processor 202 can convert this rotational speed to a value of ΔV _CROWN to determine a new scroll speed V _T . Since the display previously had a non-zero scroll speed value (eg, as shown in FIG. 24), the new value of ΔV _CROWN corresponding to rotation speed 2310 is replaced by the previous scroll speed value V _(T−1) ( for example, with scroll speed 2308). Therefore, new scroll speed 2312 can be greater than scroll speed 2308 as long as the new value of ΔV _CROWN is greater than the value of ΔV _DRAG . However, new scroll speed 2312 can be less than scroll speed 2308 if the value of ΔV _CROWN corresponding to rotational speed 2310 is less than the value of ΔV _DRAG . In the illustrated example, it is assumed that the new ΔV _CROWN value is greater than the ΔV _DRAG value. At block 2108, processor 202 may cause display 106 to update the display based on the determined scroll speed and direction. As shown in FIG. 25, this update causes the line of text to translate upward at scroll speed 2312 . Scroll speed 2312 can be greater than scroll speed 2308 because the value of ΔV _CROWN corresponding to rotational speed 2310 is greater than the value of ΔV _DRAG . As a result, the line of text has been translated a greater distance over the same amount of time, such that 1.5 lines of text have been vertically translated out of the display.

Referring now to FIG. 26, the crown 108 is being rotated in an upward rotational direction at a rotational speed 2314 that can be greater than the rotational speed 2310 . Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 2104 . Therefore, at block 2110, processor 202 can convert this rotational speed to a value of ΔV _CROWN to determine a new scroll speed V _T . Since the display previously had a non-zero scroll speed value (eg, as shown in FIG. 25), the new ΔV _CROWN value corresponding to rotation speed 2314 is replaced by the previous scroll speed value V _(T−1) ( for example, with scroll speed 2312). Therefore, new scroll speed 2316 can be greater than scroll speed 2312 as long as the new value of ΔV _CROWN is greater than the value of ΔV _DRAG . However, if the value of ΔV _CROWN corresponding to rotational speed 2314 is less than the value of ΔV _DRAG , new scroll speed 2316 can be less than scroll speed 2312 . In the illustrated example, it is assumed that the new ΔV _CROWN value is greater than the ΔV _DRAG value. At block 2108, processor 202 may cause display 106 to update the display based on the determined scroll speed and direction. As shown in FIG. 26, this update causes the line of text to translate upward at scroll speed 2316 . Scroll speed 2316 can be greater than scroll speed 2312 because the value of ΔV _CROWN corresponding to rotational speed 2314 is greater than the value of ΔV _DRAG . As a result, the lines of text are translated a greater distance over the same length of time, thereby causing two lines of text to be vertically translated out of the display.

Referring now to Figure 27, the crown 108 has not been rotated in any direction. Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 2104 . Therefore, at block 2110, processor 202 may determine a new scroll speed V _T based on the previous scroll speed V _(T−1) (eg, with scroll speed 2316) and the value of ΔV _DRAG . . Therefore, as long as the previous scroll speed 2316 is greater than the value of ΔV _DRAG , the scroll speed can have a non-zero value even when no crown rotation is being performed. However, if the previous scroll speed V _(T-1) (eg, with scroll speed 2316) is equal to the value of ΔV _DRAG , the scroll speed may have a value of 0. In the illustrated example, it is assumed that the previous scroll speed V _(T-1) (eg, with scroll speed 2316) is greater than the value of ΔV _DRAG . At block 2108, processor 202 may cause display 106 to update the display based on the determined scroll speed and direction. As shown in FIG. 27, this update causes the line of text to translate upward at scroll speed 2318 . Since ΔV _DRAG can have a non-zero value, and the previous scroll speed V _(T−1) (eg, with scroll speed 2316) can be greater than the value of ΔV _DRAG , scrolling Speed 2318 may have a non-zero value less than scroll speed 2316 . As a result, the lines of text have been translated a shorter distance over the same amount of time, such that 1.5 lines of text have been vertically translated out of the display.

Referring now to Figure 28, the crown 108 has not been rotated in any direction. Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 2104 . Therefore, at block 2110, processor 202 may determine a new scroll speed V _T based on the previous scroll speed V _(T−1) (eg, with scroll speed 2318) and the value of ΔV _DRAG . . Therefore, as long as the previous scroll speed 2318 is greater than the value of ΔV _DRAG , the scroll speed can have a non-zero value even when no crown rotation is being performed. However, if the previous scroll speed V _(T-1) (eg, with scroll speed 2318) is equal to the value of ΔV _DRAG , the scroll speed may have a value of 0. In the illustrated example, it is assumed that the previous scroll speed V _(T-1) (eg, with scroll speed 2318) is greater than the value of ΔV _DRAG . At block 2108, processor 202 may cause display 106 to update the display based on the determined scroll speed and direction. As shown in FIG. 28, this update causes the line of text to translate upward at scroll speed 2320 . Since ΔV _DRAG can have a non-zero value, and the previous scroll speed V _(T−1) (eg, with scroll speed 2318) can be greater than the value of ΔV _DRAG , the scroll Speed 2320 may have a non-zero value less than scroll speed 2318 . As a result, the line of text is translated a shorter distance over the same length of time, thereby translating one line of text vertically out of the display.

Referring now to Figure 29, the crown 108 has not been rotated in any direction. Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 2104 . Therefore, at block 2110, processor 202 may determine a new scroll speed V _T based on the previous scroll speed V _(T−1) (eg, having scroll speed 2320) and the value of ΔV _DRAG . . Therefore, as long as the previous scroll speed 2320 is greater than the value of ΔV _DRAG , the scroll speed can have a non-zero value even when no crown rotation is being performed. However, if the previous scroll speed V _(T-1) (eg, with scroll speed 2320) is equal to the value of ΔV _DRAG , the scroll speed may have a value of 0. In the illustrated example, it is assumed that the previous scroll speed V _(T-1) (eg, with scroll speed 2320) is greater than the value of ΔV _DRAG . At block 2108, processor 202 may cause display 106 to update the display based on the determined scroll speed and direction. As shown in FIG. 29, this update causes the line of text to translate upward at scroll speed 2322 . Since ΔV _DRAG can have a non-zero value, and the previous scroll speed V _(T−1) (eg, having a scroll speed of 2320) can be greater than the value of ΔV _DRAG , the scroll Speed 2322 may have a non-zero value less than scroll speed 2320 . As a result, the line of text has been translated a shorter distance over the same length of time, such that 0.5 lines of text have been vertically translated out of the display. This decay in scroll speed can continue until the previous scroll speed V _(T-1) equals the value of ΔV _DRAG , thereby dropping the scroll speed to zero. Alternatively, scroll speed decay can continue until the previous scroll speed V _(T-1) drops below a threshold, after which it can be set to a value of zero.

To further explain the operation of process 2100, FIG. 30 shows an exemplary interface of device 100 with a visual representation of lines of text containing numbers 1-9 similar to that shown in FIG. 31-36 show scroll speeds 3104, 3108, 3112, 3116, 3118, and 3120 based on input rotational speeds 3102, 3106, 3110, and 3114 in a manner similar to that described above with respect to FIGS. shows scrolling of the display in . Therefore, the length of time between subsequent views shown in FIGS. 31-36 is equal. For illustrative purposes, FIGS. 37-40 show subsequent views of the interface shown in FIG. 36 at different times. Here the length of time between each view is equal.

In contrast to FIG. 29, where no rotation input was received, in FIG. 37 a downward rotation with rotation speed 3702 can be performed. In this example, processor 202 may again receive crown position information reflecting this downward rotation from encoder 204 at block 2104 . At block 2106, processor 202 can convert this rotational speed into a ΔV _CROWN value to determine a new scroll speed V _T . Since the downward rotation of the crown 108 is in the opposite direction of scrolling as shown in FIG. 36, the value of ΔV _CROWN can have a polarity that is opposite that of the previous scroll speed value V _(T−1) . can. In some examples, the new scroll speed V _T is obtained by adding a new ΔV _CROWN value (with opposite polarity) to the previous scroll speed value V _(T−1) and subtracting the ΔV _DRAG value. can be calculated. In other examples, such as that shown in FIG. 37, when the rotation of crown 108 is in the opposite direction to that of the previous scroll (eg, the polarity of ΔV _CROWN is opposite that of V _(T−1) ). , the previous scroll velocity value V _(T-1) can be set to zero. This can be done to allow the user to quickly change scroll direction without having to offset the previous scroll speed. At block 2108, processor 202 may cause display 106 to update the display based on the determined scroll speed and direction. As shown in FIG. 37, this update causes the line of text to translate downward at scroll speed 3704 . Since the crown 108 has just started to rotate, the rotation speed 3702 can be relatively low compared to the typical rotation speed of the crown. Therefore, the scroll speed 3704 can also have relatively low values compared to typical or maximum scroll speeds. As a result, a relatively slow scroll can be performed whereby 0.5 lines of text are vertically translated out of the display.

Referring now to FIG. 38, the crown 108 is being rotated in a downward rotational direction at a rotational speed 3706 that can be greater than rotational speed 3702 . Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 2104 . Therefore, at block 2106, processor 202 can convert this rotational speed to a value of ΔV _CROWN to determine a new scroll speed V _T . Since the display previously had a non-zero scroll speed value (eg, as shown in FIG. 37), the new value of ΔV _CROWN corresponding to rotation speed 3706 is replaced by the previous scroll speed value V _(T−1) ( for example, with scroll speed 3704). Therefore, new scroll speed 3708 can be greater than scroll speed 3704 as long as the new value of ΔV _CROWN is greater than the value of ΔV _DRAG . However, new scroll speed 3708 can be less than scroll speed 3704 if the value of ΔV _CROWN corresponding to rotational speed 3706 is less than the value of ΔV _DRAG . In the illustrated example, it is assumed that the new ΔV _CROWN value is greater than the ΔV _DRAG value. At block 2108, processor 202 may cause display 106 to update the display based on the determined scroll speed and direction. As shown in FIG. 38, this update causes the line of text to translate downward at scroll speed 3708 . Scroll speed 3708 can be greater than scroll speed 3704 because the value of ΔV _CROWN corresponding to rotational speed 3706 is greater than the value of ΔV _DRAG . As a result, the line of text has been translated a greater distance over the same amount of time, such that a full line of text has been vertically translated out of the display.

Referring now to FIG. 39, the crown 108 is being rotated in a downward rotational direction at a rotational speed 3710 that can be greater than the rotational speed 3706 . Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 2104 . Therefore, at block 2106, processor 202 can convert this rotational speed to a value of ΔV _CROWN to determine a new scroll speed V _T . Since the display previously had a non-zero scroll speed value (eg, as shown in FIG. 38), the new ΔV _CROWN value corresponding to rotation speed 3710 is replaced by the previous scroll speed value V _(T−1) ( for example, with scroll speed 3708). Therefore, new scroll speed 3712 can be greater than scroll speed 3708 as long as the new value of ΔV _CROWN is greater than the value of ΔV _DRAG . However, new scroll speed 3712 can be less than scroll speed 3708 if the value of ΔV _CROWN corresponding to rotational speed 3710 is less than the value of ΔV _DRAG . In the illustrated example, it is assumed that the new ΔV _CROWN value is greater than the ΔV _DRAG value. At block 2108, processor 202 may cause display 106 to update the display based on the determined scroll speed and direction. As shown in FIG. 39, this update causes the line of text to translate downward at scroll speed 3712 . Scroll speed 3712 can be greater than scroll speed 3708 because the value of ΔV _CROWN corresponding to rotational speed 3710 is greater than the value of ΔV _DRAG . As a result, the line of text has been translated a greater distance over the same amount of time, such that 1.5 lines of text have been vertically translated out of the display.

Referring now to FIG. 40, the crown 108 is being rotated in a downward rotational direction at a rotational speed 3714 that can be greater than rotational speed 3710 . Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 2104 . Therefore, at block 2110, processor 202 can convert this rotational speed to a value of ΔV _CROWN to determine a new scroll speed V _T . Since the display previously had a non-zero scroll speed value (eg, as shown in FIG. 39), the new ΔV _CROWN value corresponding to rotation speed 3714 is replaced by the previous scroll speed value V _(T−1) ( for example, with scroll speed 3712). Therefore, new scroll speed 3716 can be greater than scroll speed 3712 as long as the new value of ΔV _CROWN is greater than the value of ΔV _DRAG . However, if the value of ΔV _CROWN corresponding to rotational speed 3714 is less than the value of ΔV _DRAG , new scroll speed 3716 can be less than scroll speed 3712 . In the illustrated example, it is assumed that the new ΔV _CROWN value is greater than the ΔV _DRAG value. At block 2108, processor 202 may cause display 106 to update the display based on the determined scroll speed and direction. As shown in FIG. 40, this update causes the line of text to translate downward at scroll speed 3716 . Scroll speed 3716 can be greater than scroll speed 3712 because the value of ΔV _CROWN corresponding to rotational speed 3714 is greater than the value of ΔV _DRAG . As a result, the lines of text are translated a greater distance over the same length of time, thereby causing two lines of text to be vertically translated out of the display.

Although not shown, when the crown 108 stops rotating, the view can continue to be scrolled downward in a manner similar to that described above with respect to FIGS. The speed and amount of scrolling that can be performed can depend on the scrolling speed when the crown 108 stops rotating and the value used for ΔV _DRAG .

Although specific scrolling examples are provided, it should be appreciated that process 2100 can be used in a similar manner to similarly scroll other types of data, such as media items, web pages, applications, or the like. be understood. For example, process 2100 may be executed to scroll through a list of applications in a manner similar to that described above with respect to process 300 . However, the speed at which the application is scrolled when using process 2100 can depend on the angular rotational speed of the crown.

FIG. 41 shows an illustrative process 4100 for scaling a display view based on the angular rotational speed of the crown, according to various examples. A view can include a visual representation of any kind of data that is displayed. For example, views can include presentations of text, media items, web pages, or the like. Process 4100 is similar to process 2100, except that process 4100 may determine a scaling rate (eg, amount and direction of size change per unit time) rather than determining scrolling rate. can be. Although the amounts determined are different, they can be determined in a similar manner. In some examples, process 4100 can be performed by a wearable electronic device similar to device 100 . In these examples, content or any other view can be displayed on display 106 of device 100 and process 4100 is performed to visually scale the view in response to rotation of crown 108. can be done.

At block 4102, a view of the wearable electronic device's display may be displayed. As mentioned above, a view can include any visual representation of any type of data displayed by the device's display.

At block 4104 , crown position information may be received in a manner similar or identical to that described above with respect to block 902 of process 900 . For example, crown position information can be received from an encoder (eg, encoder 204) by a processor (eg, processor 202) and can be used to determine the absolute position of the crown, changes in rotational position of the crown, or other positional information of the crown. It can include analog or digital representations.

At block 4106, scaling speed (eg, speed and positive/negative scaling direction) may be determined. In some examples, view scaling may be determined using physics-based motion modeling. For example, scaling speed can be treated as the speed of a moving object. The rotation of the crown can be treated as a force applied to the object in the direction corresponding to the direction of rotation of the crown. Here, the amount of force depends on the angular rotation speed of the crown. As a result, the scaling speed can be increased or decreased and can move in different directions. For example, a greater angular rotation speed can correspond to a greater amount of force applied to the object. Any desired linear or non-linear correspondence between angular rotational speed and force applied to the object can be used. Additionally, a drag force can be applied in a direction opposite to the direction of motion (eg, scaling). This can be used to decay the scaling rate over time, allowing scaling to stop without additional input from the user. Therefore, the scaling speed at discrete times can take the general form:

In Equation 1.2, V _T represents the determined scaling velocity (speed and direction) at time T and V _(T−1) represents the previous scaling velocity (speed and direction) at time T−1. , .DELTA.V.sub _{.-- CROWN} represent changes in scaling velocity caused by applied forces in response to crown rotation, and .DELTA.V.sub _{.-- DRAG} represent changes in scaling velocity caused by drag forces opposing the movement of the scaling. As mentioned above, the force exerted by the crown on the scaling can depend on the angular rotational speed of the crown. Therefore, ΔV _CROWN can also depend on the angular rotational speed of the crown. Generally, the greater the angular rotational speed of the crown, the greater the value of ΔV _CROWN . However, the actual mapping between crown angular rotation speed and ΔV _CROWN can vary depending on the desired user feel of the scaling effect. In some examples, ΔV _DRAG can be dependent on the scaling speed, such that larger speeds can produce larger opposite scaling changes. In other examples, ΔV _DRAG can have a constant value. However, it should be understood that any constant or variable amount of opposite velocity change may be used to produce the desired scaling effect. Typically, in the absence of user input in the form of ΔV _CROWN , VT will approach (and go to) 0 based on _{ΔV DRAG} according to Equation 1.2, whereas _VT is the crown Note that without user input in the form of rotation (ΔV _CROWN ), it would not change sign.

As can be seen from Equation 1.2, the scaling speed can continue to increase as long as ΔV _CROWN is greater than ΔV _DRAG . In addition, the scaling rate can have a non-zero value even when no ΔV _CROWN input has been received. Therefore, if the view is scaling at a non-zero rate, it can continue to scale even if the user does not rotate the crown. The scaling amount and time until scaling stops can depend on the scaling speed when the user stops rotating the crown, and the ΔV _DRAG component.

In some examples, the V _(T−1) component can be reset to a value of 0 when the crown is rotated in the opposite direction, corresponding to a scaling direction that is opposite to the direction in which the view is currently scaled. It allows the user to quickly change the direction of scaling without having to provide enough force to offset the current scaling speed of the view.

At block 4108 , the display may be updated based on the scaling speed and direction determined at block 4106 . This may include scaling the view in a direction corresponding to the determined scaling direction (eg, greater or lesser) by an amount corresponding to the determined scaling speed. The process can then return to block 4104, where additional crown position information can be received.

It should be appreciated that blocks 4104, 4106, and 4108 can be repeatedly executed at any desired frequency to continuously determine the scaling speed and update the display accordingly.

To further explain the operation of process 4100 , FIG. 42 shows an exemplary interface of device 100 with an image of triangle 4202 . At block 4102 of process 4100 , processor 202 of device 100 may cause display 106 to display triangle 4202 as shown. At block 4104 , processor 202 may receive crown position information from encoder 204 . At block 4106, scaling speed and scaling direction may be determined. Since the current scroll speed is 0 and the crown 108 is not currently being rotated, using equation 1.2 it can be determined that the new scaling speed is 0. At block 4108 , processor 202 may cause display 106 to update the display with the speed and direction determined at block 4106 . However, since the velocity determined was 0, no changes need to be made to the display. For illustrative purposes, FIGS. 43 and 44 show subsequent views of the interface shown in FIG. 42 at different times. Here the length of time between each view is equal.

Referring now to FIG. 43, crown 108 is being rotated in an upward rotational direction at rotational speed 4302 . Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 4104 . Therefore, at block 4106, processor 202 can convert this rotation speed to a ΔV _CROWN value to determine a new scaling speed V _T . In this example, an upward crown rotation coincides with a positive scaling direction (eg, increasing the size of the view). In other examples, other orientations can be used. At block 4108, processor 202 may cause display 106 to update the display based on the determined scaling speed and direction. As shown in FIG. 43, this update causes the size of triangle 4202 to increase at a rate of change corresponding to the determined scaling speed. Since the crown 108 has just started to rotate, the rotation speed 4302 can be relatively low compared to the typical rotation speed of the crown. Therefore, the scaling speed can also have relatively low values compared to the typical or maximum scrolling speed. As a result, only small changes in the size of triangle 4202 can be observed.

Referring now to FIG. 43, crown 108 is being rotated in an upward rotational direction at rotational speed 4304 , which can be greater than rotational speed 4302 . Processor 202 may again receive crown position information reflecting this rotation from encoder 204 at block 4104 . Therefore, at block 4106, processor 202 can convert this rotation speed to a ΔV _CROWN value to determine a new scaling speed V _T . Since the display previously had a non-zero scaling speed value (eg, as shown in FIG. 43), the new value of ΔV _CROWN corresponding to rotation speed 4304 is changed to the previous scaling speed value V _(T−1) . can be added. Therefore, as long as the new ΔV _CROWN value is greater than the ΔV _DRAG value, the new scaling speed can be greater than the previous scaling speed. However, if the value of ΔV _CROWN corresponding to rotation speed 4304 is less than the value of ΔV _DRAG , the new scaling speed can be less than the previous scaling speed. In the illustrated example, it is assumed that the new ΔV _CROWN value is greater than the ΔV _DRAG value. At block 4108, processor 202 may cause display 106 to update the display based on the determined scaling speed and direction. As shown in FIG. 44, this update causes the size of triangle 4202 to increase at the determined scaling speed. Because the value of ΔV _CROWN corresponding to rotation speed 4304 is greater than the value of ΔV _DRAG , the scaling speed can be greater than the previous scaling speed. As a result, a greater change in size of triangle 4202 than that shown in FIG. 43 can be observed.

Similar to scrolling performed using process 2100, scaling of the view containing triangle 4202 can continue after crown 108 stops rotating. However, due to the value of ΔV _DRAG in Equation 1.2, the rate at which the size of the view containing triangle 4202 increases may decrease over time. Additionally, similar scaling can be performed to reduce the size of the view containing triangle 4202 in response to crown 108 being rotated in the opposite direction. The speed of scaling can be calculated in a manner similar to that used to calculate the positive scaling shown in Figures 42-44. Further, similar to scrolling performed using process 2100, scaling speed and direction can be set to zero in response to rotation of crown 108 in a direction opposite to the direction of scaling. This can be done to allow the user to quickly change the direction of scaling.

Further, in some examples, velocity scaling can reverse direction when the minimum or maximum scaling of the view is reached. For example, the scaling speed can cause the view to zoom in at a non-zero speed. When the scaling limit is reached, the direction of scaling can be reversed, causing the view to scale in the opposite direction (e.g., zoom out) at the same speed at which it scaled before reaching the scaling limit. can be done.

In some examples, the scrolling or scaling performed in any of the processes described above (e.g., processes 300, 900, 1500, 2100, or 4100) stops in response to changes in the context of the electronic device. can be made Context can represent any conditions that make up the environment in which crown position information is being received. For example, the context may include the current application being run by the device, the type of application or process being displayed by the device, the selected object within the device's view, or the like. By way of example, if during execution of process 300 crown position information is received indicating a change in the position of crown 108, device 100 will display a list of applications as described above. can be scrolled. However, in response to a change of context in which the user selects one of the displayed applications, thereby causing device 100 to open that application, device 100 may select within the opened application To prevent the scroll function from being performed, the previous execution of the scroll function of block 306 can be stopped. In some examples, after detecting a change in context, the device 100 also ignores input from the crown 108 by ceasing execution of the scroll function of block 306, even though the crown 108 continues to be rotated. can be done. In some examples, device 100 may refrain from performing the scrolling function of block 306 in response to changes in the position of crown 108 for a threshold amount of time after detecting a change in context. The threshold length of time can be any desired amount of time, such as 1 second, 2 seconds, 3 seconds, 4 seconds, or greater than 4 seconds. Similar behavior may also be performed in response to detecting a change in context while performing processes 900 or 1500 . For example, device 100 may cease performing a previously performed scrolling or scaling function in response to detecting a change in context. Additionally, in some examples, after detecting a change in context, device 100 also scrolls or zooms the view in response to changes in the position of crown 108 for a threshold amount of time after detecting a change in context. It is also possible to ignore input from the crown 108 by not doing so. Similar behavior may also be performed in response to detecting a change in context while executing blocks 2100 or 4100 . For example, in response to detecting a change in context, device 100 may stop a previously occurring scrolling or zooming function with a non-zero speed. Additionally, in some examples, after detecting a change in context, device 100 also scrolls or zooms the view in response to changes in the position of crown 108 for a threshold amount of time after detecting a change in context. It is also possible to ignore input from the crown 108 by not doing so. Stopping scrolling or scaling functions in response to detecting a change in context and/or ignoring future input from the crown 108 ensures that any input that is injected while operating in one context is Carrying over to another context in an undesired manner can be advantageously prevented. For example, the user can use process 300 to scroll through a list of applications using the crown 108 and select a desired music application while the crown 108 continues to spin due to the momentum of the crown 108 . . Without stopping the scrolling function in response to detecting a change in context and ignoring input from the crown 108, the device 100 may cause the scrolling function to be performed within the selected application, or the crown It may result in interpreting input from 108 in other ways (eg, adjusting the volume of a music application) that were not intended by the user.

In some examples, certain types of context changes may not result in device 100 stopping an ongoing scrolling or scaling function and/or device 100 may exit from crown 108 in the future. input may not be ignored. For example, if device 100 is simultaneously displaying multiple views or objects within display 106, selection between the displayed views or objects may cause device 100 to perform scrolling or scaling functions, as described above. It may not stop and/or the device 100 may not ignore future inputs on the crown 108 . For example, device 100 can simultaneously display two sets of lines of text similar to that shown in FIG. In this example, device 100 can scroll through one of the sets using process 900 . In response to user selection of the other set of lines of text (eg, via a tap on a touch-sensitive display of device 100 at a location corresponding to the other set of lines of text), device 100 changes the previous scroll speed And/or based on the current detected change in crown 108 position, the other set of lines of text may begin scrolling. However, if a different kind of context change occurs (e.g., a new application is opened, an item not currently displayed by device 100 is selected, or the like), device 100 may As noted, scrolling or scaling functions in progress can be halted and/or input from crown 108 can be ignored for a threshold amount of time. In another example, in response to user selection of the other set of lines of text (eg, via a tap on the touch-sensitive display of device 100 at a location corresponding to the other set of lines of text), the previous scrolling Rather than begin scrolling the other set of lines of text based on the change in speed and/or current crown 108 position, the device 100 can stop the scrolling or scaling function in progress, and /or input from the crown 108 can be ignored for a threshold amount of time. However, the threshold length of time is used for changes in other types of context changes (e.g., a new application is opened, an item not currently displayed by device 100 is selected, or the like). can be less than the threshold length of time allowed. Although particular types of context changes are provided above, it should be understood that any type of context change may be selected.

In some examples, device 100 may include a mechanism for detecting physical contact with crown 108 . For example, device 100 may include a capacitive sensor configured to detect a change in capacitance caused by contact with crown 108 , a resistor configured to detect a change in resistance caused by contact with crown 108 . A sensor, a pressure sensor configured to detect depression of the crown 108 caused by contact with the crown 108, a temperature sensor configured to detect a change in temperature of the crown 108 caused by contact with the crown 108, or the like. can include those of It should be appreciated that any desired mechanism for detecting contact with crown 108 may be used. In these examples, the presence of contact with crown 108 to stop scrolling or scaling performed in any of the processes described above (e.g., processes 300, 900, 1500, 2100, or 4100). Or nonexistent can be used. For example, in some examples, device 100 may be configured to perform scrolling or scaling functions as described above with respect to processes 300, 900, 1500, 2100, or 4100. In response to detecting an abrupt cessation of rotation of crown 108 (e.g., a stop or a decrease in rotational speed above a threshold) while contact with crown 108 is detected, device 100 detects scrolling that is being performed. Or scaling can be stopped. This event may represent a situation in which the user rotates the crown 108 rapidly but intentionally stops it, indicating a request to stop scrolling or scaling. However, in response to detecting a sudden cessation of rotation of crown 108 (e.g., stopping or a decrease in rotational speed above a threshold) while contact with crown 108 is not detected, device 100 executes scrolling or scaling can continue. This event causes the user to rapidly rotate the crown 108 by performing a forward or backward flip gesture, remove their finger from the crown 108, and use another flip gesture to wind the crown 108 further. It can represent a situation in which the wrist is rotated backwards. In this situation, the user likely did not intend the scrolling or scaling to stop.

Although processes 300, 900, 2100, and 4100 have been described above as being used to perform scrolling or scaling of objects or views of a display, they may be any type of value associated with an electronic device. It should be appreciated that it can be applied more generally to adjust the . For example, rather than scrolling or scaling the view in a particular direction in response to changes in the position of the crown 108, the device 100 instead displays a selected value (e.g., volume, time in video, or any other values) can be increased by a certain amount or speed in a manner similar to that described above for scrolling or scaling. Additionally, rather than scrolling or scaling the view in opposite directions in response to changes in the position of the crown 108 in opposite directions, the device 100 instead adjusts the selected value to that described above for scrolling or scaling. can be reduced by a certain amount or speed in a manner similar to .
