Abstract

The present invention relates to the manipulation of a user interface on a wearable electronic device using a mechanical crown. In some examples, the user interface may be scrolled or scaled in response to rotation of the crown. The scrolling direction or the scaling direction, and the amount of scrolling or the amount of scaling may depend on the rotation direction and the rotation amount of the crown, respectively. In some examples, the amount of scrolling or the amount of scaling may be proportional to the change in the angle of rotation of the crown. In other examples, the scrolling speed, or scaling speed, may depend on the speed of angular rotation of the crown. In these examples, a higher rotational speed may cause scrolling or scaling to be performed on a view displayed at a higher speed.

Technical field

The present invention relates generally to a wearable electronic device, and more particularly to interfaces for a wearable electronic device.

Advanced personal electronic devices have a small form factor. These personal electronic devices may include tablets and smartphones, but are not limited thereto. The use of such personal electronic devices entails manipulation of a user interface object on a display screen, which also has a small form factor, to complement the design of the personal electronic device.

Example operations that users may perform on a personal electronic device may include navigating a hierarchy, selecting a user interface object, adjusting the position, size, and zoom of a user interface object, or other manipulation of user interfaces. Exemplary user interface objects may include digital images, video, text, icons, maps, control elements such as buttons, and other graphics. The user may perform such manipulation in image management software, video editing software, word processing software, for example a software execution platform such as the desktop of an operating system, website browsing software, and other environments.

Existing methods for manipulating user interface objects on a small-sized touch-sensitive display may be inefficient. In addition, existing methods provide generally insufficient accuracy to be considered desirable.

The present invention relates to the manipulation of a user interface on a wearable electronic device using a mechanical crown. In some examples, the user interface may be scrolled or scaled in response to rotation of the crown. The scrolling direction or the scaling direction, and the amount of scrolling or the amount of scaling may depend on the rotation direction and the rotation amount of the crown, respectively. In some examples, the amount of scrolling or the amount of scaling may be proportional to the change in the angle of rotation of the crown. In other examples, the scrolling speed, or scaling speed, may depend on the velocity of angular rotation of the crown. In these examples, the higher the rotational speed, the higher the speed of scrolling or scaling may be performed on the displayed view.

In the following description of the disclosure and examples, reference is made to the accompanying drawings, in which specific examples that may be practiced are shown by way of example within the drawings. It will be appreciated that other examples may be practiced and structural changes may be made without departing from the scope of the disclosure.

The present invention relates to manipulation of a user interface on a wearable electronic device using a mechanical crown. In some examples, the user interface may be scrolled or scaled in response to rotation of the crown. The scrolling direction or scaling direction, and the scrolling amount or scaling amount may each depend on the rotational direction and the rotational amount of the crown. In some examples, the amount of scrolling or the amount of scaling may be proportional to the change in the angle of rotation of the crown. In other examples, the scrolling speed, or scaling speed, may depend on the angular rotational speed of the crown. In these examples, the higher the rotational speed, the higher the speed of scrolling or scaling may be performed on the displayed view.

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

In the past, the term'crown' refers to a cap for winding a watch on top of a stem in the context of a watch. In the context of a personal electronic device, a crown may be a physical component of an electronic device, rather than a virtual crown on a touch-sensitive display. Crown 108 may have a mechanical meaning, ie it may be connected to a sensor for converting the physical motion of the crown into an electrical signal. Crown 108 can rotate in two directions of rotation (eg, front and rear). The crown 108 may also be pushed toward the body of the device 100 and/or pulled out of the device 100. The crown 108 may be, for example, a touch sensing type using capacitive touch technology capable of detecting whether a user is touching the crown. In addition, the crown 108 may be further rocked in one or more directions or translated along an edge of the body 102 or an at least partially circumscribed track. In some examples, more than one crown 108 may be used. The visual appearance of the crown 108 may, but need not, resemble the crown of conventional watches. If buttons 110, 112, 114 are included, they may be physical or touch sensitive buttons, respectively. That is, the buttons may be physical buttons or capacitive buttons, for example. In addition, the body 102, which may include a bezel, may have predetermined regions functioning as buttons on the bezel.

The display 106 may include display devices such as, for example, a liquid crystal display (LCD), a light emitting diode (LED) display, an organic light emitting diode (OLED) display, etc., such as mutual capacitive touch sensing, self capacitive touch sensing, It may be partially or wholly located behind or in front of a touch sensor panel implemented using any desirable touch sensing technique, such as resistive touch sensing, projection scan touch sensing, or the like. The display 106 allows a user to perform various functions by touching or hovering close to the touch sensor panel using one or more fingers or other objects.

In some examples, device 100 may 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 the display 106 can be used as an input to the device 100 to perform any desired action, e.g., selecting, entering or leaving a menu, creating a display of additional options/actions, etc. . In some examples, different actions may be performed based on the amount of force or pressure applied to the display 106. One or more pressure sensors may additionally be used to determine the location of the force applied to the display 106.

2 is a block diagram of some of the components of device 100. As shown, the crown 108 can be coupled with the encoder 204, which observes the physical state of the crown 108 or a change in the physical state (e.g., the position of the crown), converts it to an electrical signal, and (E.g., converting it into an analog or digital signal representation of the position or position change of the crown 108), it may be configured to provide a signal to the processor 202. For example, in some examples, the encoder 204 detects the absolute rotational position of the crown 108 (e.g., an angle between 0 and 360 degrees) and outputs an analog or digital representation of this position to the processor 202. Can be configured. Alternatively, in other examples, the encoder 204 detects a change in the rotational position of the crown 108 (e.g., a change in rotational angle) over a predetermined sampling period and sends an analog or digital representation of the detected change to the processor 202. It can be configured to output. In these examples, the crown position information may additionally refer to the rotation direction of the crown (eg, a positive value may correspond to one direction and a negative value may correspond to another direction). In still other examples, encoder 204 may be configured to detect rotation of crown 108 according to any desired manner (e.g., speed, acceleration, etc.) and provide crown rotation information to processor 202. I can. The rotational speed can be expressed in a variety of ways. For example, the speed of rotation is the direction and speed of rotation, such as hertz, rotations per unit of time, rotations per frame, revolutions per unit of time, rotations per frame. (revolutions per frame), change in angle per unit of time, etc. In alternative examples, instead of providing information to processor 202, such information may be provided to other components of device 100. The examples described herein are described as using the rotational position of the crown 108 to control scrolling or scaling of the view, but it will be appreciated that any other physical state of the crown 108 may be used.

In some examples, the physical state of the crown can control physical properties of the display 106. For example, if the crown 108 is in a specific position (eg, rotated forward), the display 106 may have limited z-axis transverse capability. In other words, the physical state of the crown may represent the physical modal functionality of the display 106. In some examples, a temporal attribute of the physical state of the crown 108 may be used as an input to the device 100. For example, a rapid change in a physical state can be interpreted differently than a slow change in a physical state.

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

3 is a diagram of an exemplary process 300 for scrolling a displayed set of applications using a crown according to various examples. In some examples, process 300 may be performed by a wearable electronic device similar to device 100. In such examples, a visual representation of one or more applications of the application set (eg, icons, graphic images, text images, etc.) may be displayed on the display 106 of the device 100, and the crown 108 Process 300 may be performed to visually scroll through the set of applications by sequentially displaying the applications in response to turning. In some examples, scrolling may be performed by moving the displayed content along a fixed axis.

In step 302, crown location information may be received. In some examples, the 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, the crown position information may include an analog or digital representation of a change in the rotational position of the crown, for example a change in the angle of rotation. For example, an encoder similar to encoder 204 may be coupled to a crown similar to crown 108 to observe and measure its position. The encoder may convert the position of the crown 108 into crown position information that may be transmitted to a processor similar to the processor 202.

In step 304, it may be determined whether a position change has been detected. In some examples, when the crown position information includes the absolute position of the crown, determining whether a position change has occurred may be performed by comparing the position of the crown in two different temporal instances. For example, the processor (e.g., processor 202) may determine the latest position of the crown (e.g., crown 108) indicated by the crown position information, and a view of the crown 108 indicated by the previously received crown position information. The previous (eg, just before) location can be compared. When the positions are the same or within a threshold value (eg, a value corresponding to the tolerance of the encoder), it may be determined that no position change has occurred. However, if the positions are not the same or at least differ by a threshold value, it may be determined that a position change has occurred. In other examples, if the crown position information includes a position change over a length of time, determining whether the position change occurs is whether the absolute value of the position change is equal to zero or a threshold value ( For example, this can be done by determining whether it is less than a value corresponding to the tolerance of the encoder). When the absolute value of the position change is equal to zero or less than the threshold value, it may be determined that the position change has not occurred. However, when the absolute value of the position change is zero or higher than the threshold value, it may be determined that the position change has occurred.

If it is determined in step 304 that no change in the position of the crown has been detected, the process returns to step 302 and new crown position information may be received. However, if it is determined in step 304 that the reverse position change of the crown is detected, the process may proceed to step 306. As described herein, a positive determination at step 304 may cause the process to proceed to step 306, while a negative determination may cause the process to return to step 302. However, it will be appreciated that the decision made in step 304 can be reversed, i.e., a positive decision may cause the process to return to step 302, while a negative decision may cause the process to proceed to step 306. For example, alternatively step 304 may determine if no position change is detected.

At step 306, at least a portion of the application set may be scrolled based on the detected position change. The application set may include any ordered or unordered application set. For example, the application set may include all applications stored on the wearable electronic device, all applications opened on the wearable electronic device, an application set of user selection, and the like. Additionally, applications may be ordered based on frequency of use, user-defined ordering, relevance, or any other desired ordering.

In some examples, step 306 may include visually scrolling the set of applications by sequentially displaying the applications in response to a detected change in position of the crown. For example, a display (eg, display 106) may be displaying one or more applications from a set of applications. In response to detecting a change in the position of the crown (e.g., crown 108), one or more applications currently displayed are moved away from the display and translated off to make room for one or more other applications to be moved onto the display. can do. In some examples, one or more other applications that are moved onto the display may be selected for display based on a relative ordering within the set of applications corresponding to a direction opposite to the direction of movement. The direction of movement may depend on the direction of change of position of the crown. For example, turning the crown clockwise may cause scrolling in one direction of the display, while rotating the crown counterclockwise may cause scrolling in a second (eg, counter) direction of the display. Additionally, the scrolling distance or speed may depend on the amount of detected change in the position of the crown. The scrolling distance may refer to an on-screen distance through which the content is scrolled. The scrolling speed may refer to the distance the content is scrolled over a length of time. In some examples, the scrolling distance or speed may be proportional to the amount of rotation detected. For example, the amount of scrolling corresponding to half turning of the crown may be equal to 50% of the amount of scrolling corresponding to full turning of the crown. In some examples where the set of applications includes an ordered list of applications, scrolling may stop in response to reaching the end of the list. In other examples, scrolling can continue by bypassing the other end of the application list. The process then returns to step 302 where new crown location information may be received.

It will be appreciated that the actual values used to linearly map the position change of the crown to the scrolling distance or speed may vary depending on the desired functionality of the device. Further, it will be appreciated that other mappings between the amount or speed of scrolling and the change in the position of the crown may be used. For example, acceleration, speed (described in detail below with reference to FIGS. 21 to 44), etc. may be used to determine the scrolling distance or speed. Additionally, non-linear mappings between crown feature (eg, position, velocity, acceleration, etc.) and scrolling amount or scrolling speed may be used.

To illustrate the operation of process 300 in more detail, FIG. 4 shows a visual representation of application 406 (e.g., icons, graphic images, text images, etc.), and visual representation of applications 404, 408. Shows an exemplary interface of device 100 with portions of representations. Applications 404, 406, 408 can be any number of ordered or unordered applications (e.g., all applications on device 100, all open applications on device 100, user favorites, etc.) It may be part of an application set that includes a group. In step 302 of process 300, processor 202 of device 100 may receive crown position information from encoder 204. Since the crown 108 is not rotating in FIG. 4, a negative decision is made by the processor 202 in step 304, and the process may return to step 302.

Referring now to FIG. 5, crown 108 is being rotated upward as indicated by rotational direction 502. In step 302 of process 300, processor 202 may receive crown position information reflecting this rotation back from encoder 204. Accordingly, the processor 202 may make an affirmative decision in step 304 and cause the process to proceed to step 306. In step 306, processor 202 may cause display 106 to scroll through at least a portion of the set of applications on device 100. Scrolling may have a scrolling amount or speed based on the scrolling direction 504 corresponding to the rotational direction 502 of the crown 108 and the rotational characteristics of the crown 108 (eg, distance, speed, acceleration, etc.). In the illustrated example, the scrolling distance may be proportional to the amount of rotation of the crown 108. As shown, display 106 can scroll a set of applications by causing visual representations of the applications to move in the scrolling direction 504. As a result, the application 408 has been completely removed from the display 106, a portion of the application 406 has been removed from the display 106, and a larger portion of the application 404 is displayed on the display 106. As the user continues to rotate the crown 108 in the rotational direction 502, the processor 202 continues to cause the display 106 to scroll the view of the application set in the scrolling direction 504, as shown in FIG. ) To scroll. In FIG. 6, the application 406 is barely visible on the right side of the display 106, the application 404 is located in the center inside the display 106, and the newly displayed application 402 is located on the left side of the display 106. Is displayed on. In this example, application 402 may be another application within the set of applications, and may have an ordered position to the left of application 404 or before. In some examples, if application 402 is the first application in the list of applications, and the user continues to rotate crown 108 in rotation direction 502, processor 202 places application 402 centered inside the display. If so, scrolling of the display 106 may be limited to stop scrolling. Alternatively, in other examples, the processor 202 continues scrolling of the display 106 by bypassing to the end of the application set so that the last application in the application set (e.g., application 408) is left of the application 402. Can be displayed on.

Referring now to FIG. 7, the crown 108 is being rotated in the downward rotation direction 506. In step 302 of process 300, processor 202 may receive crown position information reflecting this rotation back from encoder 204. Accordingly, the processor 202 may make an affirmative decision in step 304 and cause the process to proceed to step 306. In step 306, the processor 202 may cause the display 106 to scroll the view of the applications in a scrolling direction 508 corresponding to the rotation direction 506. In this example, the scrolling direction 508 is opposite to the scrolling direction 504. However, it will be appreciated that the scrolling direction 508 can be any desired direction. Similar to scrolling performed in response to the rotation of the rotational direction 502 of the crown 108, the scrolling performed in response to the rotation of the rotational direction 506 of the crown 108 is the rotational characteristic of the crown 108 (e.g. , Distance, speed, acceleration, etc.). In the illustrated example, the scrolling distance may be proportional to the amount of rotation of the crown 108. As shown, the display 106 can scroll a set of applications by causing visual representations of the applications to move in the scrolling direction 508. As a result, the application 402 has been completely removed from the display 106, a portion of the application 404 has been removed from the display 106, and a larger portion of the application 406 is displayed on the display 106. As the user continues to rotate the crown 108 in the rotational direction 506, the processor 202 continues to cause the display 106 to scroll the view of the application set in the scrolling direction 508, as shown in FIG. ) To scroll. In FIG. 8, the application 404 is barely visible on the left side of the display 106, the application 406 is centered inside the display 106, and the application 408 is displayed again on the right side of the display 106. do. In some examples, if application 408 is the last application in the list of applications, and the user continues to rotate crown 108 in rotation direction 508, processor 202 places application 408 centered inside the display. If so, scrolling of the display 106 may be limited to stop scrolling. Alternatively, in other examples, the processor 202 continues scrolling of the display 106 by bypassing the beginning of the application set so that the first application in the application set (e.g., application 402) is to the right of application 408. Can be displayed on.

While specific examples of scrolling have been provided, it will be appreciated that other displays of the application can be similarly scrolled using the mechanical crown of a wearable electronic device in a similar manner. Additionally, the scrolling distance or speed can be configured to depend on any feature of the crown.

9 is a diagram of an exemplary process 900 for scrolling a view of a display using a crown according to various examples. The view can include a visual representation of any type of data displayed. For example, a view may include a display of text, media items, web pages, maps, and the like. Process 900 may be similar to process 300, but more generally applied to any type of content or view displayed on the display of the device. In some examples, process 900 may be performed by a wearable electronic device similar to device 100. In these examples, content or any other view may be displayed on the display 106 of the device 100, and the process 900 may be performed to visually scroll the view in response to turning the crown 108. have. In some examples, scrolling may be performed by moving the displayed content along a fixed axis.

In step 902, crown location information may be received in a manner similar or identical to that described above for step 302. For example, crown position information may be received by a processor (e.g., processor 202) from an encoder (e.g., encoder 204), and the absolute position of the crown, a change in the rotational position of the crown, or other position of the crown. It may contain an analog or digital representation of the information.

In step 904, it may be determined whether a position change has been detected in a manner similar or identical to that described above for step 304. For example, step 904 may include comparing the position of the crown at two different temporal instances, or may include determining whether the absolute value of the crown position change is equal to zero or less than a threshold. If no change in location is detected, the process may return to step 902. Alternatively, if a change in location is detected, the process can proceed to step 906. As described herein, an affirmative determination at step 904 may cause the process to proceed to step 906, while a negative determination may cause the process to return to step 902. However, it will be appreciated that the decision made in step 904 can be reversed, i.e., an affirmative decision may cause the process to return to step 902, while a negative decision may cause the process to proceed to step 906. For example, alternatively step 904 may determine if no position change is detected.

In step 906, the view of the display may be scrolled based on the detected position change. Similar to step 306 of process 300, step 906 may include visually scrolling the view by moving the view of the display in response to a detected change in the 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 may move away from the display and disappear, thereby making room for other portions of the content that were not previously displayed. The direction of movement may depend on the direction of change of position of the crown. For example, turning the crown clockwise may cause scrolling in one direction of the display, while rotating the crown counterclockwise may cause scrolling in a second (eg, counter) direction of the display. Additionally, the scrolling distance or speed may depend on the amount of detected change in the position of the crown. In some examples, the scrolling distance or speed may be proportional to the amount of rotation detected. For example, the amount of scrolling corresponding to half turning of the crown may be equal to 50% of the amount of scrolling corresponding to full turning of the crown. The process then returns to step 902 where new crown position information may be received.

It will be appreciated that the actual values used to linearly map the position change of the crown to the scrolling distance or speed may vary depending on the desired functionality of the device. Further, it will be appreciated that other mappings between the amount of scrolling and the position change may be used. For example, acceleration, speed (described in detail below with reference to FIGS. 21 to 44), etc. may be used to determine the scrolling distance or speed. Additionally, non-linear mappings between crown feature (eg, position, velocity, acceleration, etc.) and scrolling amount or scrolling speed may be used.

To further illustrate the operation of process 900, FIG. 10 shows an example interface of device 100 with a visual representation of lines of text comprising numbers 1-9. In step 902 of process 900, processor 202 of device 100 may receive crown position information from encoder 204. Since the crown 108 is not rotating in FIG. 10, a negative decision is made by the processor 202 in step 904, and the process may return to step 902.

Referring now to FIG. 11, the crown 108 is being rotated in the upward rotation direction 1102. In step 902 of process 900, processor 202 may again receive crown position information reflecting this rotation from encoder 204. Accordingly, the processor 202 may make an affirmative decision in step 904 to advance the process to step 906. At step 906, processor 202 may cause display 106 to scroll through the lines of text being displayed on display 106. The scrolling may have a scrolling amount or speed based on the scrolling direction 1104 corresponding to the rotational direction 1102 of the crown 108 and the rotational characteristics of the crown 108 (eg, distance, speed, acceleration, etc.). In the illustrated example, the scrolling distance may be proportional to the amount of rotation of the crown 108. As shown, the display 106 can scroll lines of text by causing the lines of text to move in the scrolling direction 1104. As a result, a portion of the row 1002 has been removed from the display 106 while a portion of the row 1004 is newly displayed on the bottom of the display 106. Lines of text between lines 1002 and 1004 were similarly moved in the scrolling direction 1104. As the user continues to rotate the crown 108 in the rotational direction 1102, the processor 202 continues to cause the display 106 to move the text lines in the scrolling direction 1104, as shown in FIG. You can make it scroll. In FIG. 12, row 1002 is no longer visible on display 106, and row 1004 is now completely within the view of display 106. In some examples, if line 1004 is the last shortening of the text, and the user continues to rotate crown 108 in rotational direction 1102, processor 202 causes line 1004 to be centered inside display 106 When fully displayed, scrolling of the display 106 may be restricted to stop scrolling. In other examples, the processor 202 may cause the first line of text (e.g., line 1002) to be displayed below line 1004 by continuing scrolling of the display 106 by bypassing the beginning of the lines of text. . In still other examples, display a blank space below the row 1004 and snap back the text lines so that the row 1004 is aligned with the bottom of the display 106 in response to stopping rotation of the crown 108. ) A rubber banding effect can be performed. It will be appreciated that the action performed in response to reaching the end of the content displayed inside the display 106 may be selected based on the type of data displayed.

Referring now to FIG. 13, the crown 108 is being rotated in the downward rotation direction 1106. In step 902 of process 900, processor 202 may again receive crown position information reflecting this rotation from encoder 204. Accordingly, the processor 202 may make an affirmative decision in step 904 to advance the process to step 906. At step 906, the processor 202 may cause the display 106 to scroll the text lines in a scrolling direction 1108 corresponding to the rotational direction 1106. In this example, the scrolling direction 1108 is opposite to the scrolling direction 1104. However, it will be appreciated that the scrolling direction 1108 can be any desired direction. Similar to scrolling performed in response to rotation of the rotational direction 1102 of the crown 108, scrolling performed in response to rotation of the rotational direction 1106 of the crown 108 is the rotational characteristic of the crown 108 (e.g. , Distance, speed, acceleration, etc.). In the illustrated example, the scrolling distance may be proportional to the amount of rotation of the crown 108. As shown, the display 106 can scroll lines of text by causing the lines of text to move in the scrolling direction 1108. As a result, a portion of the row 1004 may have been removed from the display 106 while a portion of the row 1002 may be displayed again on top of the display 106. As the user continues to rotate the crown 108 in the rotation direction 1106, the processor 202 continues to cause the display 106 to move the text lines in the scrolling direction 1108, as shown in FIG. You can make it scroll. As shown in Fig. 14, while the line 1004 has moved away from the display 106, the line 1002 is now fully visible. In some examples, if line 1002 is the first decrease in text, and the user continues to rotate crown 108 in rotation direction 1106, processor 202 places line 1002 on top of display 106 If so, scrolling of the display 106 may be limited to stop scrolling. In other examples, processor 202 may cause the last line of text (eg, line 1004) to be displayed over line 1002 by continuing scrolling of display 106 by bypassing to the end of the lines of text. In still other examples, a rubber band effect that displays a blank space above the string 1002 and causes the lines of text to bounce back so that the string 1002 is aligned with the top of the display 106 in response to stopping rotation of the crown 108. Can be performed. It will be appreciated that the action performed in response to reaching the end of the content displayed inside the display 106 may be selected based on the type of data displayed.

While specific examples of scrolling have been provided, it will be appreciated that other data types, such as media items, webpages, etc., can be similarly scrolled using the mechanical crown of a wearable electronic device in a similar manner. Additionally, the scrolling distance or speed can be configured to depend on any feature of the crown.

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

In step 1502, crown location information may be received in a manner similar or identical to that described above for steps 302 or 902. For example, crown position information may be received by a processor (e.g., processor 202) from an encoder (e.g., encoder 204), and the absolute position of the crown, a change in the rotational position of the crown, or other position of the crown. It may contain an analog or digital representation of the information.

In step 1504, it may be determined whether a position change has been detected in a manner similar or identical to that described above for step 304 or step 904. For example, step 1504 may include comparing the position of the crown at two different temporal instances, or may include determining whether the absolute value of the crown position change is equal to or less than a threshold value. If no change in location is detected, the process may return to step 1502. Alternatively, if a change in location is detected, the process can proceed to step 1506. As described herein, an affirmative determination at step 1504 may cause the process to proceed to step 1506, while a negative determination may cause the process to return to step 1502. However, it will be appreciated that the decision made in step 1504 may be reversed, i.e., a positive decision may cause the process to return to step 1502, while a negative decision may cause the process to proceed to step 1506. For example, alternatively step 1504 may determine if no position change is detected.

In step 1506, the view of the display may be scaled based on the detected position change. Step 1506 may include visual scaling of the view (eg, zoom in/out) in response to a detected change in the 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 (e.g., the crown 108), the view may be scaled by increasing or decreasing the size of the currently displayed portion of the content in the view according to the direction of the change in the position of the crown. have. For example, rotating the crown clockwise increases (e.g., zooms in) the size of the content in the view of the display, while rotating the crown counterclockwise decreases the size of the content in the view of the display (e.g. Out). Additionally, the scaling amount or scaling speed may depend on the detected amount of change in the position of the crown. In some examples, the scaling amount or scaling speed may be proportional to the detected amount of rotation of the crown. For example, the amount of scaling corresponding to a half turn of the crown may be equal to 50% of the amount of scaling corresponding to a full turn of the crown. The process then returns to step 1502 so that new crown position information may be received.

It will be appreciated that the actual values used to linearly map the crown position change to the amount or speed of scaling may vary depending on the desired function of the device. Furthermore, it will be appreciated that other mappings between the amount of scaling and the position change may be used. For example, acceleration, speed (described in detail below with reference to FIGS. 21 to 44), and the like may be used to determine the amount or speed of scaling. Additionally, non-linear mappings between crown feature (eg, position, velocity, acceleration, etc.) and scaling amount or scrolling speed may be used.

To further illustrate the operation of process 1500, FIG. 16 shows an exemplary interface of device 100 showing triangle 1602. In step 1502 of process 1500, processor 202 of device 100 may receive crown position information from encoder 204. Since the crown 108 is not rotating in FIG. 16, a negative decision is made by the processor 202 at step 1504, and the process may return to step 1502.

Referring now to FIG. 17, the crown 108 is being rotated in the upward rotation direction 1702. In step 1502 of process 1500, processor 202 may again receive crown position information reflecting this rotation from encoder 204. Accordingly, the processor 202 may make an affirmative decision in step 1504 and allow the process to proceed to step 1506. In step 1506, processor 202 may cause display 106 to scale the view being displayed on device 106. Scaling can increase or decrease the size of the view depending on the rotation direction 502 of the crown 108, and the scaling amount or speed based on the rotational characteristics of the crown 108 (e.g., distance, speed, acceleration, etc.) Can have. In the illustrated example, the amount of scaling may be proportional to the amount of rotation of the crown 108. As shown, display 106 may scale the view including triangle 1602 using a positive scaling factor. As a result, the triangle 1602 of FIG. 17 is larger than that of FIG. 16. As the user continues to rotate the crown 108 in the rotational direction 1702, as shown in FIG. 18, the processor 202 continues to cause the display 106 to cause the triangle ( 1602). In FIG. 18, triangles 1602 are shown larger than those shown in FIGS. 16 and 17. When the rotation of the crown 108 stops, the scaling of the view, including the triangle 1602, similarly stops. In some examples, if the view of the triangle 1602 has been scaled to its maximum amount and the user continues to rotate the crown 108 in the rotation direction 1702, the processor 202 may limit the scaling of the display 106. have. In still other examples, allowing the size of the view, including the triangle 1602 to be increased to a rubber band limit that exceeds the maximum scaling amount of the view, and then in response to stopping rotation of the crown 108, the size of the view is increased to its maximum. The rubber band effect can be performed by making it bounce back to the amount of scaling. It will be appreciated that the action performed in response to reaching the scaling limit of the display 106 can be configured in any desired manner.

Referring now to FIG. 19, crown 108 is being rotated in a downward rotation direction 1704. In step 1502 of process 1500, processor 202 may again receive crown position information reflecting this rotation from encoder 204. Accordingly, the processor 202 may make an affirmative decision in step 1504 and allow the process to proceed to step 1506. In step 1506, processor 202 may cause display 106 to scale the view using a negative scaling factor corresponding to rotation direction 1704. Similar to the scaling performed in response to the rotation of the rotational direction 1702 of the crown 108, the scaling performed in response to the rotation of the rotational direction 1704 of the crown 108 is the rotational characteristic of the crown 108 (e.g. , Distance, speed, acceleration, etc.). In the illustrated example, the amount of scaling may be proportional to the amount of rotation of the crown 108. As shown, the display 106 can scale the view including the image of the triangle 1602 using a negative scaling factor. As a result, the triangle 1602 of FIG. 19 appears to be smaller than that of FIG. 18. As the user continues to rotate the crown 108 in the rotation direction 1704, as shown in FIG. 20, the processor 202 continues to cause the display 106 to cause the triangle ( 1602). In FIG. 20, triangles 1602 are smaller than those shown in FIGS. 18 and 19. When the rotation of the crown 108 stops, the scaling of the view including the triangle 1602 may similarly stop. In some examples, if the view including the triangle 1602 has been scaled to its maximum amount and the user continues to rotate the crown 108 in the rotation direction 1704, the processor 202 will limit the scaling of the display 106. I can. In still other examples, allow the size of the view including triangle 1602 to be reduced to a rubber band limit that is less than the minimum scaling amount of the view, and then in response to stopping rotation of the crown 108, the size of the view is reduced to its minimum scaling amount. The rubber band effect can be performed by making it bounce back to. It will be appreciated that the action performed in response to reaching the scaling limit of the display 106 can be configured in any desired manner.

While specific examples of scaling have been provided, it will be appreciated that views of other data types, such as media items, webpages, etc., can be similarly scaled using the mechanical crown of a wearable electronic device in a similar manner. Additionally, the scaling amount or speed can be configured to depend on any feature of the crown. In addition, in some examples, upon reaching the minimum or maximum scaling of the view, continued rotation of the crown in the same direction may cause scaling in the opposite direction. For example, an upward rotation of the crown may cause the view to zoom in. However, once the scaling limit is reached, an upward rotation of the crown may cause the view to scale (eg, zoom out) in the opposite direction.

21 is a diagram of an exemplary process 2100 for scrolling a view of a display based on the angular rotational speed of the crown according to various examples. The view can include a visual representation of any type of data displayed. For example, a view may include a display of text, media items, web pages, and the like. The process 2100 may be similar to the process 900, but may scroll the view based on a scrolling speed dependent on the angular rotational speed of the crown. In some examples, process 2100 may be performed by a wearable electronic device similar to device 100. In these examples, content or any other view may be displayed on the display 106 of the device 100, and the process 2100 may be performed to visually scroll the view in response to turning the crown 108. have. In some examples, scrolling may be performed by moving the displayed content along a fixed axis.

In step 2102, a view of the display of the wearable electronic device may be displayed. As noted above, a view may include any visual representation of any type of data displayed by the device's display.

At step 2104, crown position information may be received in a manner similar or identical to that described above for step 902 of process 900. For example, crown position information may be received by a processor (e.g., processor 202) from an encoder (e.g., encoder 204), and the absolute position of the crown, a change in the rotational position of the crown, or other position of the crown. It may contain an analog or digital representation of the information.

In step 2106, a scrolling speed (eg, speed and scrolling direction) may be determined. In some examples, scrolling of the view can be determined using physics-based modeling of motion. For example, a view may be treated as an object with a movement speed corresponding to the scrolling speed across the display of the device. The 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, where the amount of force depends on the speed of angular rotation of the crown. For example, a higher angular rotational speed may correspond to a greater amount of force applied to the view. Any desired linear or nonlinear mapping can be used between the angular rotational speed of the crown and the force applied to the view. Additionally, a drag force may be applied in a direction opposite to the scrolling direction. This can be used to attenuate the scrolling speed over time to stop scrolling in the absence of additional input from the user. Thus, the scrolling speed at discrete moments in time can take the general form:

V _T =V _(T-1) + ΔV _CROWN -ΔV _DRAG . ( 1.1 )

In Equation 1.1, V _T represents the scrolling speed (speed and direction) determined at time T, V _(T-1) represents the previous scrolling speed (speed and direction) at time T-1, and ΔV _CROWN is the crown's It represents the change in velocity caused by the force applied to the view in response to rotation, and ΔV _DRAG represents the change in the velocity of the view caused by the drag force opposite to the motion of the view (scrolling of the view). As mentioned above, the force applied to the view by the crown may depend on the angular rotational speed of the crown. Thus, ΔV _CROWN can also depend on the angular rotational speed of the crown. Typically, the higher the angular rotational speed of the crown, the higher the ΔV _CROWN value will be. However, the actual mapping between each rotational speed of the crown and ΔV _CROWN may vary depending on the desired user feel for the scrolling effect. For example, various linear or nonlinear mappings between angular rotational speed of the crown and ΔV _CROWN can be used. In some examples, as [Delta]V _DRAG depends on the scrolling speed, the higher the speed, the higher the opposite speed change can be produced. In other examples, ΔV _DRAG can have a constant value. However, it will be appreciated that any constant or variable inverse velocity variation can be used to produce the desired scrolling effect. Typically, in the absence of user input of the form ΔV _CROWN , V _T will approach (and reach) zero based on ΔV _DRAG according to Equation 1.1, but V _T is the sign without user input in the form of crown rotation (ΔV _CROWN ). Note that will not change.

As can be seen from Equation 1.1, the scrolling speed can continue to increase as long as ΔV _CROWN is higher than ΔV _DRAG . Additionally, the scrolling speed may have a non-zero value even when no ΔV _CROWN input is received. Thus, if the view scrolls at a non-zero speed, it can continue to scroll without the user's crown rotation. The scrolling distance and time to stop scrolling may depend on the scrolling speed and ΔV _DRAG factor at any point in time when the user stops rotating the crown.

In some examples, when the crown is rotated in a direction corresponding to the scrolling direction opposite to the current scrolling direction of the view, the V _(T-1) element is reset to a zero value so that the user cancels the current scrolling speed of the view. It can allow you to quickly change the scrolling direction without having to provide enough force.

In step 2108, the display may be updated based on the scrolling speed and direction determined in step 2106. This may include moving the displayed view by an amount corresponding to the determined scrolling speed and in a direction corresponding to the determined scrolling direction. The process then returns to step 2104 where additional crown location information may be received.

It will be appreciated that steps 2104, 2106, 2108 may be repeated at any desired frequency to continuously determine the scrolling speed and update the display accordingly.

To further illustrate the operation of process 2100, FIG. 22 shows an example interface of device 100 with a visual representation of lines of text comprising numbers 1-9. At step 2102 of process 2100, processor 202 of device 100 may cause display 106 to display the illustrated interface. In step 2104, the processor 202 may receive crown position information from the encoder 204. In step 2106, a scrolling speed and a scrolling direction may be determined. Since the current scrolling speed is zero and the crown 108 is not currently rotating, it can be determined that the new speed of scrolling is zero using Equation 1.1. In step 2108, the processor 202 may cause the display 106 to update the display using the speed and direction determined in step 2106. However, since the determined speed is zero, no changes need to be made to the display. For illustrative purposes, FIGS. 23 to 29 show subsequent views at different points of time of the interfaces shown in FIG. 22, where the length of time between each view is the same.

Referring now to FIG. 23, the crown 108 is being rotated in an upward rotational direction with a rotational speed 2302. In step 2104, the processor 202 may again receive crown position information reflecting this rotation from the encoder 204. Thus, in step 2106, the processor 202 may convert this rotational speed to a value of ΔV _CROWN to determine a new scrolling speed V _T. In this example, the rotation of the crown 108 in the upward direction corresponds to the upward scrolling direction. In other examples, other directions may be used. In step 2108, the processor 202 may cause the display 106 to update the display based on the determined scrolling speed and direction. As shown in Fig. 23, this update caused the lines of text to move upward with a scrolling speed 2304. Since the crown 108 has just started rotating, the rotational speed 2302 may be relatively low compared to the typical rotational speeds of the crown. Thus, similarly, scrolling speed 2304 may have a relatively low value compared to typical or maximum scrolling speeds. As a result, only part of the line of text containing the value "1" has been moved away from the display.

Referring now to FIG. 24, crown 108 is being rotated in an upward rotational direction with rotational speed 2306 which may be higher than rotational speed 2302. In step 2104, the processor 202 may again receive crown position information from the encoder 204. Thus, in step 2106, the processor 202 may convert this rotational speed to a value of ΔV _CROWN to determine a new scrolling speed V _T. Previously the display had a non-zero speed value (e.g., as shown in Figure 23), so the new ΔV _CROWN value corresponding to the rotational speed 2306 is the previous scrolling (e.g., with the scrolling speed 2304). It can be added to the speed value V _(T-1) . Thus, as long as the new ΔV _CROWN value is higher than the ΔV _DRAG value, the new scrolling speed 2308 may be higher than the scrolling speed 2304. However, when the ΔV _CROWN value corresponding to the rotational speed 2306 is lower than the ΔV _DRAG value, the new scrolling speed 2308 may be lower than the scrolling speed 2304. In the illustrated example, it is assumed that the new ΔV _CROWN value is higher than the ΔV _DRAG value. In step 2108, the processor 202 may cause the display 106 to update the display based on the determined scrolling speed and direction. As shown in FIG. 24, this update caused the lines of text to move upward with a scrolling speed 2308. Since the ΔV _CROWN value corresponding to the rotational speed 2306 is higher than the ΔV _DRAG value, the scrolling speed 2308 may be higher than the scrolling speed 2304. As a result, lines of text were moved a longer distance over the same length of time, causing an entire line of text to move vertically across the display and disappear.

Referring now to FIG. 25, crown 108 is being rotated in an upward rotational direction with a rotational speed 2310 which may be higher than rotational speed 2306. In step 2104, the processor 202 may again receive crown position information reflecting this rotation from the encoder 204. Thus, in step 2106, the processor 202 may convert this rotational speed to a value of ΔV _CROWN to determine a new scrolling speed V _T. Previously, the display had a non-zero scrolling speed value (e.g., as shown in FIG. 24), so the new ΔV _CROWN value corresponding to the rotational speed 2310 (e.g., with scrolling speed 2308) was previously It can be added to the scrolling speed value V _(T-1) . Thus, as long as the new ΔV _CROWN value is higher than the ΔV _DRAG value, the new scrolling speed 2312 may be higher than the scrolling speed 2308. However, when the ΔV _CROWN value corresponding to the rotational speed 2310 is lower than the ΔV _DRAG value, the new scrolling speed 2312 may be lower than the scrolling speed 2308. In the illustrated example, it is assumed that the new ΔV _CROWN value is higher than the ΔV _DRAG value. In step 2108, the processor 202 may cause the display 106 to update the display based on the determined scrolling speed and direction. As shown in Fig. 25, this update caused the lines of text to move upward with a scrolling speed 2312. Since the ΔV _CROWN value corresponding to the rotational speed 2310 is higher than the ΔV _DRAG value, the scrolling speed 2312 may be higher than the scrolling speed 2308. As a result, the lines of text were moved a longer distance over the same length of time, causing 1.5 lines of text to move vertically across the display and disappear.

Referring now to FIG. 26, crown 108 is being rotated in an upward rotational direction with rotational speed 2314 which may be higher than rotational speed 2310. In step 2104, the processor 202 may again receive crown position information reflecting this rotation from the encoder 204. Thus, in step 2110, the processor 202 may convert this rotational speed to a value of ΔV _CROWN to determine a new scrolling speed V _T. Previously the display had a non-zero scrolling speed value (e.g., as shown in FIG. 25), so the new ΔV _CROWN value corresponding to the rotational speed 2314 is the previous (e.g., with scrolling speed 2312). It can be added to the scrolling speed value V _(T-1) . Thus, as long as the new ΔV _CROWN value is higher than the ΔV _DRAG value, the new scrolling speed 2316 may be higher than the scrolling speed 2312. However, when the ΔV _CROWN value corresponding to the rotational speed 2314 is lower than the ΔV _DRAG value, the new scrolling speed 2316 may be lower than the scrolling speed 2312. In the illustrated example, it is assumed that the new ΔV _CROWN value is higher than the ΔV _DRAG value. In step 2108, the processor 202 may cause the display 106 to update the display based on the determined scrolling speed and direction. As shown in Fig. 26, this update caused the lines of text to move upward with a scrolling speed 2316. Since the ΔV _CROWN value corresponding to the rotational speed 2314 is higher than the ΔV _DRAG value, the scrolling speed 2316 may be higher than the scrolling speed 2312. As a result, the lines of text were moved a longer distance over the same length of time, causing the two lines of text to move vertically across the display and disappear.

Referring now to Figure 27, the crown 108 is not rotating in either direction. In step 2104, the processor 202 may again receive crown position information reflecting this rotation from the encoder 204. Accordingly, in step 2110 the processor 202 may determine a new scrolling speed V _T based on the previous scrolling speed V _(T-1) and the ΔV _DRAG value (eg, with scrolling speed 2304 ). Thus, as long as the previous scrolling speed 2316 is higher than the ΔV _DRAG value, the scrolling speed may have a non-zero value even when no rotation of the crown is performed. However, if the previous scrolling speed V _{(T-1) (} with scrolling speed 2316) is equal to the ΔV _DRAG value, the scrolling speed may have a zero value. In the illustrated example, it is assumed that the previous scrolling speed V _(T-1) (eg, with scrolling speed 2316) is higher than the ΔV _DRAG value. In step 2108, the processor 202 may cause the display 106 to update the display based on the determined scrolling speed and direction. As shown in Fig. 27, this update caused the lines of text to move upward with a scrolling speed 2318. ΔV _DRAG may have a non-zero value, and since the previous scrolling speed V _(T-1) (e.g., with scrolling speed 2316) may be higher than the ΔV _DRAG value, the scrolling speed is less than the scrolling speed 2316 It can have a low non-zero value. As a result, the lines of text were moved a shorter distance over the same length of time, causing 1.5 lines of text to move vertically across the display and disappear.

Referring now to Figure 28, the crown 108 is not rotating in either direction. In step 2104, the processor 202 may again receive crown position information reflecting this rotation from the encoder 204. Accordingly, in step 2110 the processor 202 may determine a new scrolling speed V _T based on the previous scrolling speed V _(T-1) and the ΔV _DRAG value (eg, with scrolling speed 2318 ). Thus, as long as the previous scrolling speed 2318 is higher than the ΔV _DRAG value, the scrolling speed may have a non-zero value even when no rotation of the crown is performed. However, if the previous scrolling speed V _(T-1) (eg, with scrolling speed 2318) is equal to the ΔV _DRAG value, the scrolling speed may have a value of zero. In the illustrated example, it is assumed that the previous scrolling speed V _(T-1) (eg, with scrolling speed 2318) is higher than the ΔV _DRAG value. In step 2108, the processor 202 may cause the display 106 to update the display based on the determined scrolling speed and direction. As shown in Fig. 28, this update caused the lines of text to move upward with a scrolling speed 2320. ΔV _DRAG may have a non-zero value, and since the previous scrolling speed V _{(T-1) (} with scrolling speed 2318) may be higher than the ΔV _DRAG value, the scrolling speed 2320 is equivalent to the scrolling speed ( 2318) may have a non-zero value. As a result, lines of text were moved a shorter distance over the same length of time, causing one line of text to move vertically across the display and disappear.

Referring now to Figure 29, the crown 108 is not rotating in either direction. In step 2104, the processor 202 may again receive crown position information reflecting this rotation from the encoder 204. Accordingly, in step 2110 the processor 202 may determine a new scrolling speed V _T based on the previous scrolling speed V _(T-1) and the ΔV _DRAG value (eg, with scrolling speed 2320 ). Thus, as long as the previous scrolling speed 2320 is higher than the ΔV _DRAG value, the scrolling speed may have a non-zero value even when no rotation of the crown is performed. However, if the previous scrolling speed V _(T-1) (eg, with scrolling speed 2320) is equal to the ΔV _DRAG value, the scrolling speed may have a zero value. In the illustrated example, it is assumed that the previous scrolling speed V _(T-1) (eg, with scrolling speed 2320) is higher than the ΔV _DRAG value. In step 2108, the processor 202 may cause the display 106 to update the display based on the determined scrolling speed and direction. As shown in FIG. 29, this update caused the lines of text to move upward with a scrolling speed 2322. ΔV _DRAG may have a non-zero value, and since the previous scrolling speed V _(T-1) (e.g., with scrolling speed 2320) may be higher than the ΔV _DRAG value, the scrolling speed 2322 is the scrolling speed ( 2320) may have a non-zero value. As a result, lines of text were moved a shorter distance over the same length of time, causing 0.5 lines of text to move vertically across the display and disappear. This attenuation of the scrolling speed continues until the previous scrolling speed V _(T-1) becomes equal to the ΔV _DRAG value, thereby causing the scrolling speed to drop to zero. Alternatively, the decay of the scrolling speed may continue until the previous scrolling speed V _(T-1) falls below a threshold value, after which it may be set to a zero value.

To further illustrate the operation of process 2100, similar to that shown in FIG. 22, FIG. 30 shows an exemplary interface of device 100 with a visual representation of lines of text including numbers 1-9. . 31-36 show scrolling speeds 3104, 3108, 3112, 3116, 3118, based on input rotational speeds 3102, 3106, 3110, 3114, in a manner similar to that described above for FIGS. 23-28. 3120) illustrates scrolling of a display. Accordingly, the lengths of time between views after shown in FIGS. 31 to 36 are the same. For the sake of explanation, FIGS. 37-40 show views later at different points in time of the interface shown in FIG. 36, where the length of time between each view is the same.

Unlike FIG. 29 in which no rotation input is received, in FIG. 37, downward rotation with a rotation speed 3702 may be performed. In this case, in step 2104, the processor 202 may receive crown position information reflecting this downward rotation from the encoder 204 again. In step 2106, the processor 202 may convert this rotational speed to a value of ΔV _CROWN to determine a new scrolling speed V _T. Since the downward rotation of the crown 108 is the opposite direction to the scrolling shown in FIG. 36, the value of ΔV _CROWN may have a polarity opposite to the previous scrolling speed value V _(T-1) . In some examples, the new scrolling speed V _T can be calculated by adding the new ΔV _CROWN value (with opposite polarity) and the previous scrolling speed value V _(T-1) and subtracting the ΔV _DRAG value. In other examples as shown in Fig.37, when the rotation of the crown 108 is in the opposite direction to the previous scrolling (e.g., the polarity of ΔV _{CROWN is} the opposite of V _(T-1) ), the previous scrolling speed value V _{( T-1)} can be set to zero. By performing in this way, it allows the user to quickly change the scrolling direction without having to cancel the previous scrolling speed. In step 2108, the processor 202 may cause the display 106 to update the display based on the determined scrolling speed and direction. As shown in Figure 37, this update caused the lines of text to move in a downward direction with a scrolling speed 3704. Since the crown 108 has just started rotating, the rotational speed 3702 may be relatively low compared to the typical rotational speeds of the crown. Thus, similarly scrolling speed 3704 may have a relatively low value compared to typical or maximum scrolling speeds. As a result, relatively slow scrolling can be performed, causing 0.5 lines of text to vertically shift away from the display and disappear.

Referring now to FIG. 38, crown 108 is being rotated in a downward rotational direction with rotational speed 3706, which may be higher than rotational speed 3702. In step 2104, the processor 202 may again receive crown position information reflecting this rotation from the encoder 204. Thus, in step 2106, the processor 202 may convert this rotational speed to a value of ΔV _CROWN to determine a new scrolling speed V _T. Previously, the display had a non-zero scrolling speed value (e.g., as shown in FIG. 37), so the new ΔV _CROWN value corresponding to the rotational speed 3706 was previously (e.g., with scrolling speed 3704). It can be added to the scrolling speed value V _(T-1) . Thus, as long as the new ΔV _CROWN value is higher than the ΔV _DRAG value, the new scrolling speed 3708 may be higher than the scrolling speed 3704. However, when the ΔV _CROWN value corresponding to the rotational speed 3706 is lower than the ΔV _DRAG value, the new scrolling speed 3708 may be lower than the scrolling speed 3704. In the illustrated example, it is assumed that the new ΔV _CROWN value is higher than the ΔV _DRAG value. In step 2108, the processor 202 may cause the display 106 to update the display based on the determined scrolling speed and direction. As shown in Fig. 38, this update caused the lines of text to move in a downward direction with a scrolling speed 3708. Since the ΔV _CROWN value corresponding to the rotational speed 3706 is higher than the ΔV _DRAG value, the scrolling speed 3708 may be higher than the scrolling speed 3704. As a result, lines of text were moved a longer distance over the same length of time, causing an entire line of text to move vertically across the display and disappear.

Referring now to FIG. 39, crown 108 is being rotated in a downward rotational direction with a rotational speed 3710 which may be higher than rotational speed 3706. In step 2104, the processor 202 may again receive crown position information reflecting this rotation from the encoder 204. Thus, in step 2106, the processor 202 may convert this rotational speed to a value of ΔV _CROWN to determine a new scrolling speed V _T. Previously the display had a non-zero scrolling speed value (e.g., as shown in FIG. 38), so the new ΔV _CROWN value corresponding to the rotational speed 3710 is the previous (e.g., with scrolling speed 3708). It can be added to the scrolling speed value V _(T-1) . Thus, as long as the new ΔV _CROWN value is higher than the ΔV _DRAG value, the new scrolling speed 3712 may be higher than the scrolling speed 3708. However, when the ΔV _CROWN value corresponding to the rotational speed 3710 is lower than the ΔV _DRAG value, the new scrolling speed 3712 may be lower than the scrolling speed 3708. In the illustrated example, it is assumed that the new ΔV _CROWN value is higher than the ΔV _DRAG value. In step 2108, the processor 202 may cause the display 106 to update the display based on the determined scrolling speed and direction. As shown in Fig. 39, this update caused the lines of text to move in a downward direction with a scrolling speed 3712. Since the ΔV _CROWN value corresponding to the rotational speed 3710 is higher than the ΔV _DRAG value, the scrolling speed 3712 may be higher than the scrolling speed 3708. As a result, the lines of text were moved a longer distance over the same length of time, causing 1.5 lines of text to move vertically across the display and disappear.

Referring now to FIG. 40, crown 108 is being rotated in a downward rotational direction with a rotational speed 3714 which may be higher than rotational speed 3710. In step 2104, the processor 202 may again receive crown position information reflecting this rotation from the encoder 204. Thus, in step 2110, the processor 202 may convert this rotational speed to a value of ΔV _CROWN to determine a new scrolling speed V _T. Previously, the display had a non-zero scrolling speed value (e.g., as shown in FIG. 39), so the new ΔV _CROWN value corresponding to the rotational speed 3714 is the previous (e.g., with scrolling speed 3712). It can be added to the scrolling speed value V _(T-1) . Thus, as long as the new ΔV _CROWN value is higher than the ΔV _DRAG value, the new scrolling speed 3716 may be higher than the scrolling speed 3712. However, when the ΔV _CROWN value corresponding to the rotational speed 3714 is lower than the ΔV _DRAG value, the new scrolling speed 3716 may be lower than the scrolling speed 3712. In the illustrated example, it is assumed that the new ΔV _CROWN value is higher than the ΔV _DRAG value. In step 2108, the processor 202 may cause the display 106 to update the display based on the determined scrolling speed and direction. As shown in Fig. 40, this update caused the lines of text to move in a downward direction with a scrolling speed 3716. Since the ΔV _CROWN value corresponding to the rotational speed 3714 is higher than the ΔV _DRAG value, the scrolling speed 3716 may be higher than the scrolling speed 3712. As a result, the lines of text were moved a longer distance over the same length of time, causing the two lines of text to move vertically across the display and disappear.

Although not shown, when the rotation of the crown 108 is stopped, the view can continue to be scrolled in the downward direction in a similar manner described above with respect to FIGS. 35 and 36. The scrolling speed and amount of scrolling that can be performed may depend on the scrolling speed when the rotation of the crown 108 stops and the value used as ΔV _DRAG .

While specific examples of scrolling have been provided, it will be appreciated that other data types, such as media items, webpages, applications, etc., may be similarly scrolled using process 2100 in a similar manner. For example, process 2100 may be performed to scroll through a list of applications in a manner similar to that described above for process 300. However, when using process 2100 the scrolling speed for the application may depend on the angular rotational speed of the crown.

41 is a diagram of an example process 4100 for scaling a view of a display based on the angular rotational speed of the crown according to various examples. The view can include a visual representation of any type of data displayed. For example, a view may include a display of text, media items, web pages, and the like. The process 4100 may be similar to the process 2100, except that the process 4100 does not determine a scrolling speed, but may determine a scaling speed (eg, a change amount and a change direction of a size per unit time). Different amounts can be determined, but they can be determined in a similar way. In some examples, process 4100 may be performed by a wearable electronic device similar to device 100. In these examples, content or any other view may be displayed on the display 106 of the device 100, and the process 4100 may be performed to visually scale the view in response to turning the crown 108. have.

In operation 4102, a view of the display of the wearable electronic device may be displayed. As noted above, a view may include any visual representation of any type of data displayed by the device's display.

In step 4104, crown location information may be received in a manner similar or identical to that described above for step 902 of process 900. For example, crown position information may be received by a processor (e.g., processor 202) from an encoder (e.g., encoder 204), and the absolute position of the crown, a change in the rotational position of the crown, or other position of the crown. It may contain an analog or digital representation of the information.

In step 4106, a scaling speed (eg, speed and positive/negative scaling direction) may be determined. In some examples, scaling of the view can be determined using physics-based modeling of motion. For example, the 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 a direction corresponding to the direction of rotation of the crown, where the amount of force depends on the angular rotational speed of the crown. As a result, the scaling speed can increase or decrease and can move in different directions. For example, a higher angular rotational speed may correspond to a greater amount of force applied to the object. Any desired linear or nonlinear mapping can be used between each rotational speed and the force applied to the object. Additionally, a drag force may be applied in a direction opposite to the direction of movement (eg, scaling). This can be used to attenuate the scaling rate over time to stop scaling in the absence of additional input from the user. Thus, at temporal discrete moments, the scaling speed can take the general form:

V _T =V _(T-1) + ΔV _CROWN -ΔV _DRAG . ( 1.2 )

In equation 1.2, V _T represents the scaling speed (speed and direction) determined at time T, V _(T-1) represents the previous scaling speed (speed and direction) at time T-1, and ΔV _CROWN is the crown's _Represents the scaling speed change caused by the applied force in response to rotation, and ΔV _DRAG represents the scaling speed change caused by the drag force opposing the scaling movement. As mentioned above, the force applied to the scaling by the crown may depend on the angular rotational speed of the crown. Thus, ΔV _CROWN can also depend on the angular rotational speed of the crown. Typically, the higher the angular rotational speed of the crown, the higher the ΔV _CROWN value will be. However, the actual mapping between each rotational speed of the crown and ΔV _CROWN may vary depending on the desired user feel for the scaling effect. In some examples, as [Delta]V _DRAG is dependent on the scaling rate, the higher the rate, the larger the opposite scaling change can be produced. In other examples, ΔV _DRAG can have a constant value. However, it will be appreciated that any constant or inverse rate change amount of a variable can be used to produce the desired scaling effect. Typically, in the absence of user input in the form of ΔV _CROWN , V _T will approach (and reach) zero based on ΔV _DRAG according to Equation 1.2, but V _T will be without user input in the form of crown rotation (ΔV _CROWN ). Note that the sign will not change.

As can be seen from Equation 1.2, the scaling rate can continue to increase as long as ΔV _CROWN is higher than ΔV _DRAG . Additionally, the scaling rate can have a non-zero value even if no ΔV _CROWN input is received. Thus, if the view scales at a non-zero speed, it can continue to scale without the user's crown rotation. The amount and time of scaling to stop scaling may depend on the scaling speed and ΔV _DRAG factor at the time when the user stops rotating the crown.

In some examples, if the crown is rotated in the opposite direction corresponding to the scaling direction opposite to the current scaling direction of the view, the V _(T-1) element is reset to a zero value so that the user can offset the current scaling speed of the view. It can allow you to quickly change the scaling direction without having to provide enough force.

In step 4108, the display may be updated based on the scaling speed and direction determined in step 4106. This may include scaling the view by an amount corresponding to the determined scaling speed and in a direction (eg, larger or smaller) corresponding to the determined scaling direction. The process then returns to step 4104 where additional crown position information may be received.

It will be appreciated that steps 4104, 4106, and 4108 may be repeated at any desired frequency to continuously determine the scaling rate and update the display accordingly.

To further illustrate the operation of process 4100, FIG. 42 shows an exemplary interface of device 100 with a triangle 4202 image. At step 4102 of process 4100, processor 202 of device 100 may cause display 106 to display illustrated triangle 4202. In step 4104, the processor 202 may receive crown position information from the encoder 204. In step 4106, a scaling speed and a scaling direction may be determined. Since the current scaling speed is zero and the crown 108 is not currently rotating, it can be determined that the new speed of scaling is zero using Equation 1.2. In step 4108, processor 202 may cause display 106 to update the display using the speed and direction determined in step 4106. However, since the determined speed is zero, no changes need to be made to the display. For illustrative purposes, FIGS. 43 and 44 show subsequent views at different points in time of the interface shown in FIG. 42, where the length of time between each view is the same.

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

Referring now to FIG. 43, crown 108 is being rotated in an upward rotational direction with rotational speed 4304, which may be higher than rotational speed 4302. In step 4104, the processor 202 may again receive crown position information reflecting this rotation from the encoder 204. Thus, in step 4106, the processor 202 may convert this rotational speed to a value of ΔV _CROWN to determine a new scaling speed V _T. Previously the display had a non-zero scaling speed value (e.g., as shown in FIG. 43), so a new ΔV _CROWN value corresponding to the rotational speed 4304 will be added to the previous scaling speed value V _(T-1) . I can. Thus, as long as the new ΔV _CROWN value is higher than the ΔV _DRAG value, the new scaling speed 2308 may be higher than the previous scaling speed. However, when the ΔV _CROWN value corresponding to the rotational speed 4304 is lower than the ΔV _DRAG value, the new scaling speed may be lower than the previous scaling speed. In the illustrated example, it is assumed that the new ΔV _CROWN value is higher than the ΔV _DRAG value. In step 4108, processor 202 may cause display 106 to update the display based on the determined scaling speed and direction. As shown in Figure 44, this update increased the size of the triangle 4202 using the determined scaling rate. Since the ΔV _CROWN value corresponding to the rotational speed 4304 is higher than the ΔV _DRAG value, the scaling speed may be higher than the previous scaling speed. As a result, a larger change than that shown in FIG. 43 in the size of the triangle 4202 can be observed.

Similar to scrolling performed using process 2100, scaling of the view including triangle 4202 may continue after crown 108 has ceased to rotate. However, the rate of increase in the size of the view including the triangle 4202 may decrease over time due to the ΔV _DRAG value of Equation 1.2. Additionally, similar scaling can be performed to reduce the size of the view including triangle 4202 in response to crown 108 rotating in the opposite direction. The scaling rate can be calculated in a manner similar to that used in the calculation of the positive scaling shown in FIGS. 42-44. In addition, similar to the scrolling performed using process 2100, the scaling speed and direction may be set to zero in response to rotation of the crown 108 in a direction opposite to the scaling direction. By doing this, the user is allowed to quickly change the scaling direction.

Furthermore, in some examples, when the minimum or maximum scaling of the view is reached, the scaling speed direction may be reversed. For example, the scaling speed can cause the view to zoom in using a non-zero speed. When the scaling limit is reached, the scaling direction is reversed, allowing the view to scale (eg, zoom out) in the opposite direction with the same speed as the scaling speed of the view prior to reaching the scaling limit.

In some examples, scrolling or scaling performed in any of the processes described above (e.g., process 300, 900, 1500, 2100 or 4100) may stop in response to a change in the context of the electronic device. The context may represent any condition constituting the environment in which the crown location information is received, for example, the context is the current application being executed by the device, the type of application or process being displayed by the device, and It may include a selected object in the view, etc. To illustrate this, if crown position information indicating a change in the position of the crown 108 is received during the process 300, the device 100 The list may be scrolled. However, in response to a context change in the form of a user selecting one of the displayed applications to cause the device 100 to open the application, the device 100 It is possible to prevent the scrolling function from being performed in the open application by stopping the execution of the scrolling function In some examples, even if the crown 108 continues to rotate after detecting a context change, the device 100 proceeds to step 306 It is also possible to ignore the input at the crown 108 by stopping the performance of the scrolling function of the crown 108. In some examples, the device 100 may determine the position of the crown 108 over a critical length of time after detection of a context change. In response to the change, it may stop performing the scrolling function of step 306. The threshold length of time may be any required time, such as 1, 2, 3, 4 seconds or more. Process 900 or process 1500 ), a similar behavior may also be performed in response to detecting a context change, for example, the device 100 may perform scrolling or scaling that previously occurred in response to detecting a context change. You can stop performing a function. Additionally, in some examples, after detecting a context change, over a threshold length of time after detecting the context change, the device 100 stops scrolling or zooming on the view in response to the change in the position of the crown 108 The input at (108) can also be ignored. A similar behavior may also be performed in response to detecting a context change while performing step 2100 or step 4100. For example, in response to detecting a context change, the device 100 may stop a previously generated scrolling or zooming function with a non-zero speed. Additionally, in some examples, after detecting a context change, over a threshold length of time after detecting the context change, the device 100 stops scrolling or zooming on the view in response to the change in the position of the crown 108 The input at (108) can also be ignored. Stopping the scrolling or scaling function in response to detection of a context change and/or ignoring subsequent input at crown 108 does not lead to other contexts in an undesirable manner due to inputs entered while operating as one context. It may have the advantage of preventing it. For example, a user may use the crown 108 to scroll through the list of applications using the process 300, and the momentum of the crown 108 causes the desired music to continue spinning while the crown 108 continues to spin. You can choose the application. If the scrolling function is not stopped or the input from the crown 108 is not ignored in response to the context change detection, the device 100 causes the scrolling function to be performed in the selected application, or the user intends the input from the crown 108. It can be interpreted in other ways that don't (e.g. adjust the volume of a music application).

In some examples, a certain type of context change results in device 100 stopping an ongoing scrolling or scaling function and/or causing device 100 to ignore subsequent inputs at crown 108, etc. May not be brought. For example, when the device 100 is simultaneously displaying multiple views or objects in the display 106, as described above, selection between the displayed views or objects causes the device 100 to scroll or scale. It may not cause the function to stop and/or not cause the device 100 to ignore subsequent inputs at the crown 108. For example, the device 100 may simultaneously display two sets of lines of text similar to those shown in FIG. 10. In this example, device 100 may scroll through one of the sets using process 900. In response to the user selecting another set of text lines (e.g., through tapping on the touch-sensitive display of the device 100, at a location corresponding to the other set of text lines), the device 100 Scrolling of another set of lines of text may be initiated based on the speed and/or the currently detected change in crown 108 position. However, when a different type of context change occurs (e.g., opening a new application, selecting an item that is not currently being displayed by the device 100, etc.), as described above, the device 100 has an ongoing scrolling or scaling function. And/or ignore the input at crown 108 for a certain critical length of time. In other examples, in response to the user selecting another set of text lines (e.g., through tapping on the touch-sensitive display of device 100, at a location corresponding to the other set of text lines), the previous scrolling speed And/or not starting to scroll another set of text lines based on the current position change of the current crown 108, the device 100 stops the ongoing scrolling or scaling function and/or stops the scrolling or scaling function in progress and/or in the crown 108 for a critical length of time. You can ignore the input of However, the threshold time length may be shorter than the threshold time length used for other context change types (e.g., opening a new application, selection of an item not currently being displayed by the device 100, etc.). Although we have provided for the context change of, it will be understood that any type of context change can be selected.

In some examples, device 100 may include a mechanism to detect physical contact with crown 108. For example, the device 100 may have a capaticitve sensor configured to detect a change in capacitance caused by contact with the crown 108, and a change in resistance caused by contact with the crown 108. A resistive sensor, a pressure sensor configured to detect the pressure drop in the crown 108 caused by contact with the crown 108, the temperature change of the crown 108 caused by contact with the crown 108 It may include a temperature sensor configured to detect, and the like. It will be appreciated that any desired mechanism for detecting contact with crown 108 may be used. In these examples, the presence or absence of contact with the crown 108 may be used to stop scrolling or scaling performed in any of the processes described above (e.g., process 300, 900, 1500, 2100 or 4100). . For example, in some examples, device 100 may be configured to perform the scrolling or scaling function described above with respect to processes 300, 900, 1500, 2100 or 4100. In response to detecting a sudden stop of rotation of the crown 108 while contact with the crown 108 is being detected (e.g., stopping or decreasing the rotational speed above a threshold), the device 100 may perform scrolling or You can stop scaling. This occurrence may represent a case in which the user has indicated the intention to stop scrolling or scaling by causing the crown 108 to rotate quickly but intentionally stops. However, in response to detecting a sudden stop of rotation of the crown 108 (e.g., stop or decrease in rotational speed above a threshold value) while contact with the crown 108 is not being detected, the device 100 performs You can continue scrolling or scaling in progress. This occurrence is caused by the user performing a front or rear flicking gesture, quickly rotating the crown 108, releasing the finger from the crown 108, and further using another flicking gesture. It is possible to express a case in which the user's wrist is rotated to its original position to wrap it. In this case, the user may not have intended to stop scrolling or scaling.

Although processes 300, 900, 2100, 4100 have been described above as being used to perform scrolling or scaling of an object or view of a display, they are more commonly applied to adjust any type of value associated with an electronic device. You will have to understand that you can. For example, rather than scrolling or scaling the view in a particular direction in response to a change in the position of the crown 108, the device 100 instead selects a value (e.g., volume, time in video, or any other value). May be increased by a predetermined amount or a predetermined speed in a manner similar to that described above for scrolling or scaling. Additionally, rather than scrolling or scaling the view in the opposite direction in response to a change in the position of the crown 108 in the opposite direction, the device 100 instead clears the selected value in a manner similar to that described above for scrolling or scaling. It can be reduced by a quantity or by a predetermined speed.

One or more functions relating to scaling or scrolling of the user interface may operate in a system similar or identical to system 4500 shown in FIG. 45. System 4500 may include instructions stored in a non-transitory computer readable storage medium, such as memory 4504 or storage device 4502, and executed by processor 4506. Instructions may also be used by or in connection with an instruction execution system, apparatus, or device, such as an instruction execution system, apparatus, or computer-based system, a processor-containing system, or other system capable of fetching and executing instructions from an instruction execution system, apparatus, or device.
