Because wearable equipment's screen is most less, for example, need wear on the wrist for intelligent wrist-watch, intelligent bracelet etc. therefore the size of screen has received very big restriction, and single finger slides, presses etc. the operation inconvenient at little screen operation, consequently for improving operating efficiency, intelligent wrist-watch, intelligent bracelet etc. have all been equipped with rotatable crown. The user can implement different functions by rotating the crown. For convenience of explanation, the wearable device is taken as an example of a smart watch.

Illustratively, the user can switch the interface by rotating the crown. For example, as shown in (a) and (b) of fig. 4, the smart watch displays an interface 401, the interface 401 may be a desktop of the smart watch, for example, the desktop of the smart watch includes 3 interfaces, the interface 401 is one of the interfaces, and the interface 401 may include application icons (e.g., an icon of a weather application, an icon of a music application, and an icon of an APP1 application). The smart watch detects an operation of the user rotating the crown (clockwise as shown in the figure), and in response to the operation, the smart watch may display an interface 402, and similarly, the interface 402 may be one of the interfaces of the desktop of the smart watch. At present, a contact sensor can be added in the crown and used for detecting whether a user touches the crown or not, the crown and the crown shaft are made of conductive materials, when the user touches the crown, the contact sensor can send a contact signal to a processor, so that the fact that the user is touching the crown is determined, then the intelligent watch can detect the rotating angle of the crown shaft, and corresponding functions are executed according to the rotating angle. Such as functions of switching interfaces, zooming interfaces, etc. However, the space inside the crown is very small, and the requirement for the machining process is high by adding the contact sensor in the crown, so that the yield in the production process can be reduced, and the overall hardware cost is increased.

To sum up, at present, whether wearable equipment needs to increase contact sensor in the crown in order to detect the user and contact the crown, but the inner space of crown is little, and the processing degree of difficulty that increases contact sensor in the crown is high, has reduced the qualification rate in the production process, increases holistic hardware cost. Based on this, the embodiment of the application provides an interaction method of a wearable device, which can accurately respond to the rotation operation of a user and improve the use experience of the user and the interestingness of human-computer interaction.

The following describes an interaction method of a wearable device provided in an embodiment of the present application with reference to the drawings.

FIG. 5 illustrates a set of GUIs provided by an embodiment of the present application.

When the user needs to rotate the crown, a force needs to be applied to a tangent plane of the crown so that the crown is rotated. The crown and the crown shaft are connected, when a force is applied to a tangent plane of the crown by a user, the crown and the crown shaft rotate simultaneously, in addition, as the force acts on the tangent plane of the crown, the crown shaft can generate radial deviation in the direction of the force, the wearable device can determine that the user rotates the crown by detecting the radial deviation, so that corresponding functions can be executed according to the rotation angle of the crown shaft, and the detailed description refers to the following description

The wearable device determines that the user is rotating the crown by detecting that the crown shaft is radially offset, and then the wearable device performs a corresponding function based on the angle of rotation of the crown shaft. The wearable device may distinguish different functions depending on the angle of rotation.

In some embodiments, the function of switching the interface is performed when the wearable device detects that the rotation angle of the crown shaft is greater than or equal to a first threshold. As shown in (a) and (b) of fig. 5, when the wearable device detects that the rotation angle of the crown shaft is greater than or equal to the first threshold, the interface 501 is switched to the interface 502, where the interface 501 and the interface 502 may be different interfaces of a wearable device desktop. Interface 501 and interface 502 may also be different interfaces in an application.

In other embodiments, the wearable device detects that the user is rotating the crown, and may gradually zoom in (or zoom out) the interface as the user rotates. It will be appreciated that the wearable device may determine whether the interface needs to be scaled down or scaled up by the direction of crown shaft rotation. For example, as shown in fig. 5 (a) and (c), the wearable device detects clockwise rotation of the crown shaft, and the wearable device may gradually narrow the interface as the crown shaft rotates clockwise. As the wearable device detects counterclockwise rotation of the crown shaft as shown in (a) and (d) of fig. 5, the wearable device may gradually enlarge the interface with the counterclockwise rotation of the crown shaft. Further, the interface may be switched, for example interface 501 to interface 502, when the wearable device detects that the rotation angle of the crown shaft rotating clockwise (or counterclockwise) is greater than the first threshold.

In other implementations, the wearable device detects that the user is rotating the crown, and may gradually increase (decrease) the brightness of the screen as the user rotates. It should be understood that the wearable device may determine whether the screen brightness needs to be increased or decreased by the direction in which the crown is rotated. For example, as shown in (e) and (f) of fig. 5, the wearable device detects clockwise rotation of the crown shaft, and the wearable device may increase screen brightness as the crown shaft rotates clockwise. The wearable device detects the counterclockwise rotation of the crown shaft, and the wearable device may decrease the brightness of the screen as the crown shaft rotates counterclockwise.

In other embodiments, the wearable device detects that the user is rotating the crown, and may gradually increase (decrease) the volume of the wearable device as the user rotates. It will be appreciated that the wearable device may determine whether to increase or decrease the volume by the direction the crown is rotated. For example, as shown in (g) and (h) of fig. 5, the wearable device detects a clockwise rotation of the crown shaft, and the wearable device may increase the volume as the crown shaft rotates clockwise. The wearable device detects the counterclockwise rotation of the crown shaft, and the wearable device may decrease the volume as the crown shaft rotates counterclockwise.

In other embodiments, the wearable device detects that the user is rotating the crown, and may move the interface downward (or upward) as the user rotates. For example, as shown in (i) in fig. 5, the wearable device displays the interface 503, and the interface 503 may display first content, where the first content may be multimedia information such as text, pictures, and videos, and the first content cannot be completely displayed because the screen of the wearable device is small, for example, as shown in (i) in fig. 5, the wearable device first displays a first portion of the first content in the interface 503, and as the user rotates the watch crown clockwise, the wearable device may move the interface 503 downward, as shown in (j) in fig. 5, and displays a second portion of the first content.

The following describes a method for detecting that a user touches a crown by a wearable device provided in an embodiment of the present application.

Fig. 6 shows a force analysis diagram of the crown shaft provided in the embodiment of the present application.

As shown in fig. 6 (a), a user may apply a certain force on the crown with a single finger so that the crown rotates clockwise, and the force may be decomposed into a component force in the normal direction of the crown and a component force in the tangential direction, as shown in fig. 6 (b), which is a right side view in fig. 6 (a), and when the user rotates the crown clockwise, the applied force may be divided into a first component force f1 and a second component force f2, where the first component force f1 is a force in the tangential direction and the second component force f2 is a component force in the normal direction. Since the crown is connected to the crown shaft, the first component force f1 acting on the crown can radially displace the crown shaft in the tangential direction, and the second component force f2 acting on the crown can radially displace the crown shaft in the normal direction.

In other embodiments, as shown in fig. 6 (c), the user may apply a certain force to the crown with multiple fingers (two fingers in the drawing) to rotate the crown clockwise, and similarly, the force acting on the crown may be divided into a normal-direction component force and a tangential-direction component force of the crown as shown in fig. 6 (d), which is a right-side view of fig. 6 (c), and the user may have two forces acting on the crown when rotating the crown, and one of the two forces may be divided into a third component force f3 and a fourth component force f4 and the other force may be divided into a fifth component force f5 and a sixth component force f6. Since the rotation direction of the crown is clockwise rotation, the third component force f3 is larger than the fifth component force f5, the fourth component force f4 is larger than the sixth component force f6, and similarly, the crown shaft can undergo radial deviation in the direction of the third component force f3, and radial deviation in the direction of the fourth component force f 4.

It should be understood that the present application is only exemplified by rotating the crown with a single finger and two fingers, but not limited thereto.

In summary, when the crown shaft is radially displaced, it is determined that the user is contacting and rotating the crown when a certain force is applied to the crown. Based on this, the wearable device can judge whether the user contacts and rotates the crown by detecting whether the crown shaft is radially deviated.

In some embodiments, the wearable device may determine that the crown axis is radially offset by a capacitive sensor.

The capacitance sensor consists of a capacitance variable capacitor and a measuring circuit, wherein the capacitance variable capacitor and the measuring circuit are integrated by a sensing element and a conversion element. In the embodiment of the present application, taking a plate capacitor as an example, the capacitance of the plate capacitor can be represented by formula (1):

wherein epsilon represents the dielectric constant of the medium between the capacitor plates; a is the opposite area of the capacitor plate; d is expressed as the distance between the capacitor plates.

The capacitance sensor outputs a capacitance variation amount by which a displacement difference of the radial offset of the crown shaft can be determined. It can be known from the formula (1) that one of the three parameters can be used, and the other two parameters are kept unchanged, so that the change of the changed parameter can be converted into the change of the capacitance, and the change is converted into the electric quantity output through the measuring circuit. Therefore, the types of the capacitive sensor can be classified into a variable area type, a variable dielectric type, and a variable pole pitch type.

Illustratively, the capacitive sensor is a variable-pitch type capacitive sensor. As shown in fig. 7, fig. 7 is a schematic cross-sectional view of a variable-pitch capacitive sensor, a crown shaft, and a crown. The variable-pitch capacitive sensor may include a movable plate 710 and a fixed plate 711, and the distance between the movable plate 710 and the fixed plate 711 is d ₁ 。

In some implementations, the movable plate 710 may be connected to a crown shaft 712, the crown shaft 712 being disposed above the movable plate 710, a normal direction of the crown shaft 712 being perpendicular to a plane in which the movable plate 710 is located. When the user rotates the crown 713 to cause the crown shaft 712 to radially displace in the x-direction, the movable plate 710 moves in the x-direction, and the displacement of the crown shaft 712 can be represented by the change in capacitance. For example, as shown in (a) and (b) of fig. 7, the crown shaft 712 is radially offset in the x direction so that the distance between the movable plate 710 and the fixed plate 711 becomes d ₂ Then the radial offset of the crown axis is different by Δ d = d ₁ -d ₂ . When the movable plate 710 is not moved, the capacitance of the variable-pitch capacitive sensor is set to

When the movable plate moves by delta d in the x direction, the capacitance of the variable-pitch capacitive sensor is

Wherein, C ₂ Expressed as the capacitance of the capacitive sensor at varying pole pitch, C ₁ The capacitance of the capacitor when the pole pitch is unchanged is shown, and Δ C represents the amount of change in capacitance of the variable-pitch capacitive sensor.

In some embodiments of the present invention, the,

the above equation can be simplified to

Can see C ₂ Approximately linear with the offset difference Δ d. In summary, in the embodiment of the present application, it is possible to detect the radial deviation of the crown shaft by the change in the capacitance of the variable-pitch type capacitive sensor, and determine that the user is touching and rotating the crown based on the radial deviation. The variable-pole-pitch type capacitive sensor may be provided inside the wearable device. The inner space of the wearable device is larger than that of the crown, and the radial offset of the crown axis is detected by adding a capacitance sensor in the wearable device to determine whether the user is touching andthe crown is rotated, the processing difficulty of the wearable device is reduced, and the corresponding function of user operation can be accurately executed.

In other embodiments, the problem that the capacitance of the variable-pole-pitch capacitive sensor changes due to radial deviation of a crown shaft caused by vibration and the like in the daily wearing process of the wearable device is avoided, and misjudgment is caused. The wearable device may set a threshold in the system, and the wearable device only determines that the user is contacting and rotating the crown when the change in capacitance exceeds the threshold.

Alternatively, in other embodiments, in order to avoid the radial deviation of the crown shaft caused by vibration and the like during daily wearing of the wearable device, and thus the change of the capacitance of the variable-pitch capacitive sensor, as shown in (c) and (d) of fig. 7, the crown shaft may be arranged above the movable plate, and the distance between the movable plate and the crown shaft is d ₃ The normal direction of the crown axis is perpendicular to the plane of the movable pole plate. The deviation difference of the radial deviation of the crown shaft caused by vibration and the like is smaller than the deviation difference of the radial deviation of the crown shaft caused when a user rotates the crown, and d is set reasonably ₃ And misjudgment caused by vibration and the like can be effectively avoided.

In other embodiments, a high dielectric constant material, such as mica, plastic film, etc., may be used between the plates to prevent the capacitive sensor from breaking down or shorting. By adding a high dielectric constant material between the polar plates, the initial distance between the polar plates can be reduced, and the volume of the capacitance sensor can be reduced.

In the present embodiment, the radial offset of the crown axis in the x direction is taken as an example, but the present invention is not limited thereto, and the radial offset of the crown axis in other directions, for example, the-x direction, the z direction, the-z direction, and the like may be also taken.

It should be noted that the variable-pitch capacitive sensor in the embodiment of the present application includes one movable plate and one fixed plate, but is not limited thereto, and the variable-pitch capacitive sensor may be of a differential structure, and the variable-pitch capacitive sensor of the differential structure may include two fixed plates and one movable plate.

Illustratively, the capacitive sensor is a variable area type capacitive sensor. As shown in fig. 8, fig. 8 is a schematic cross-sectional view of the variable area capacitive sensor, the crown shaft, and the crown. The variable area capacitive sensor may include a movable plate 810 and a fixed plate 811, and the distance between the movable plate 810 and the fixed plate 811 is d ₄ . The movable plate 810 may move in the x-direction or the-x-direction.

In some embodiments, the movable plate 810 may be coupled with a crown shaft 812. When the user rotates the crown 813 to cause the radial displacement of the crown axis 812 in the x direction, the movable plate 810 moves in the x direction, and the displacement difference of the radial displacement of the crown axis 812 can be represented by the change of the capacitance. For example, as shown in fig. 8 (a) and (b), when the length and width of the movable plate 810 and the fixed plate 811 are a and b, respectively (the width of the plates is not shown), the facing area of the movable plate 810 and the fixed plate 811 is a × b, the crown axis 812 is radially offset in the x direction by an offset Δ d ₁ The area of the movable plate 810 and the fixed plate 811 facing each other is (a- Δ d) ₁ ) X b. Therefore, according to the formula (1), the amount of change in capacitance can be expressed as,

wherein, Δ C ₁ Expressed as the amount of change in capacitance, C, of the variable-area type capacitive sensor ₃ Expressed as the capacitance of the capacitive sensor before the area directly opposite the plates has not changed, C ₄ The capacitance of the capacitive sensor after the change of the area of the opposite surfaces of the polar plates is expressed. As can be seen from the above formula, Δ C ₁ And Δ d ₁ In a linear relationship, the variable-area capacitive sensor can determine the displacement of the movable plate by detecting the amount of change in capacitance, and the wearable device can determine the radial offset of the crown shaft and, based on the radial offset, determine that the user is contacting and rotating the crown.

In other embodiments, the variable area capacitive sensor may be a coaxial cylinder capacitive sensor. FIG. 9 shows a coaxial cylindrical capacitive sensor and a watch, as shown in (a) and (b) of FIG. 9In the schematic diagrams of crown shaft and crown, the pole plate 910 is a movable pole plate, the pole plate 911 is a fixed pole plate, and the pole plate is hereinafter referred to as the movable pole plate 910 and the fixed pole plate 911. The height of the movable pole plate is L, and the diameter is d ₅ The height of the fixed polar plate is L, and the diameter is d ₆ According to the formula (1), when the movable plate 910 is not displaced, the initial capacitance is

The crown shaft 912 is connected to the top of the movable plate 910, and the connection may be a mechanical connection or an adhesive connection, which is not limited in the embodiment of the present application. When the user rotates crown 913, crown shaft 912 is radially offset in the x-direction by a difference Δ d ₂ The movable plate 910 connected to the crown shaft 912 also moves in the x direction by Δ d ₂ The relative change of the capacitance at this time is

As can be seen from the above equation, the relative change amount of capacitance is linearly related to the displacement of the movable plate 910. The variable area type capacitive sensor may determine the displacement of the movable plate by detecting the amount of change in capacitance, and the wearable device may determine the radial offset of the crown shaft, and determine that the user is contacting and rotating the crown based on the radial offset.

In other embodiments, the problem that the capacitance of the variable-area capacitive sensor changes due to radial deviation of a crown shaft caused by vibration and the like in the daily wearing process of the wearable device is avoided, and misjudgment is caused. The wearable device may set a threshold in the system, and the wearable device only determines that the user is contacting and rotating the crown when the change in capacitance exceeds the threshold.

It should be understood that, in the embodiment of the present application, only the area-variable type capacitive sensor is taken as an example, but the present application is not limited thereto, and the wearable device in the embodiment of the present application may also adopt an area-variable type capacitive sensor of an angular displacement type.

In some embodiments, the wearable device may determine that the crown axis is radially offset by a rotation sensor.

Illustratively, the rotation sensor may be a reflective optical sensor. Fig. 10 is a cross-sectional view taken along the x-axis of the region 104 in fig. 1. As shown in fig. 10, the crown 1001 is connected to a crown shaft 1002, and the crown shaft 1002 extends through the case 1003. A clamping sleeve 1004 is connected to the housing 1003, the clamping sleeve 1004 is used for fixing the crown shaft 1002, and the clamping sleeve 1004 can allow the crown shaft 1002 to be radially offset while fixing the crown shaft 1002. In some embodiments, the wearable device may not include the ferrule 1004.

Crown shaft 1002 may be patterned, marked, or otherwise configured to reflect light when rotated. The rotation sensor 1005 may emit a first light to the crown shaft 1002 and receive a light reflected from the crown shaft 1002. When the crown shaft 1002 is not radially offset, the reflected light ray is the second light ray, and when the crown shaft 1002 is radially offset, the reflected light ray is the third light ray.

For example, as shown in (a) and (b) of fig. 11, when the rotation sensor 1005 may emit a first light ray to the shaft body of the crown shaft 1002, the incident angle of the first light ray is a, and when the crown shaft 1002 is not radially offset, the reflection angle of the second light ray reflected by the rotation sensor 1005 is also a, the time t of the rotation sensor 1005 from the emission of the first light ray to the arrival of the second light ray at the rotation sensor 1005 may be determined according to the distance between the rotation sensor 1005 and the crown shaft 1002 and a ° ₁ When the crown shaft 1002 is radially shifted, the incident angle of the first light ray becomes b, and the reflection angle of the third light ray reflected by the crown shaft 1002 becomes b, the time t from the emission of the first light ray by the rotation sensor 1005 to the arrival of the third light ray at the rotation sensor 1005 can be determined based on the distance between the rotation sensor 1005 and the crown shaft 1002 and b ₂ . When the wearable device detects that the time from the first light emission to the first light reception of the rotation sensor 1005 is not equal to t ₁ Then it can be determined that the crown shaft 1002 is radially offset.

Illustratively, the shaft body of the crown shaft 1002 may include at least 2 portions of different blackness coefficients, for example, as shown in (c) and (d) of fig. 11, the shaft body of the crown shaft 1002 includes 3 portions of different blackness coefficients, where the blackness coefficient of the first portion 1006 is a first coefficient, the blackness coefficient of the second portion 1007 is a second coefficient, and the blackness coefficient of the third portion 1008 is a third coefficient. When the crown shaft 1002 is not radially displaced, the light emitted from the rotation sensor 1005 strikes the second portion 1007 and is then reflected to the rotation sensor 1005, and when the crown shaft 1002 is radially displaced, the light emitted from the rotation sensor strikes the first portion 1006 and is then reflected to the rotation sensor 1005, and due to the difference in the black index between the first portion 1006 and the second portion 1007, the intensity of the light received by the rotation sensor 1005 is different, and it can be determined that the crown shaft 1002 is radially displaced.

For example, the first pattern and the second pattern may be included on the shaft body of the crown shaft 1002, when the crown shaft 1002 is not radially offset, the light emitted from the rotation sensor 1005 may be irradiated to the first pattern and then reflected to the rotation sensor 1005, when the crown shaft 1002 is radially offset, the light emitted from the rotation sensor may be irradiated to the second pattern and then reflected to the rotation sensor 1005, and since the first pattern and the second pattern are different, the information of the light received by the rotation sensor 1005 is different, and thus it may be determined that the crown shaft 1002 is radially offset.

In the embodiment of the application, the radial deviation of the crown shaft is detected through the rotary sensor, so that the fact that a user is in contact with and rotates the crown can be determined, the operation of the user can be accurately sensed under the condition that the sensor is not added, and the user experience and the interestingness of man-machine interaction are improved.

It should be understood that the embodiments of the present application only use the capacitive sensor and the rotation sensor to detect the radial offset of the crown shaft as an example, but not limited thereto, and it is within the scope of the present application to detect the radial offset of the crown shaft by other sensors and implement the methods provided by the embodiments of the present application, for example, a resistive sensor, a laser displacement sensor, an inductive displacement sensor, a hall displacement sensor, etc. may also be used.

And S1202, the wearable device judges whether the crown shaft is radially offset or not.

When the wearable device determines that the crown shaft is not radially displaced, the process proceeds to step S1204. When the crown shaft is radially offset, step S1203 is performed.

In other embodiments, step S1203 is performed when the offset difference of the radial offset of the crown shaft is greater than a threshold value.

For example, the wearable device may detect whether the crown shaft is radially offset by a capacitive sensor, and the type of the capacitive sensor may be a variable area type capacitive sensor or a variable pole pitch type capacitive sensor. The crown shaft is connected with the movable polar plate of the capacitance sensor, when the crown shaft is radially offset, the movable polar plate is displaced, so that the capacitance of the capacitance sensor is changed, and the wearable device can determine that the crown shaft is radially offset.

For example, the wearable device may detect an offset difference of the radial offset of the crown shaft by the rotation sensor. The rotation sensor may be a reflective optical sensor that emits a first light toward the crown shaft, reflects a second light toward the rotation sensor when the crown shaft is not radially offset, and reflects a third light toward the rotation sensor when the crown shaft is radially offset. The wearable device may determine that the crown axis is radially offset when the light received by the rotation sensor is a third light by detecting the light received by the rotation sensor.

As another example, as shown in (i) and (j) of fig. 5, the wearable device may move the interface.

It should be noted that in the present embodiment, when the user no longer touches and rotates the crown, the crown shaft can be reset again. Illustratively, as shown in fig. 1 (c), the wearable device is provided with a ferrule 106, and when the crown shaft is no longer stressed, the crown shaft 105 can be reset due to the action of the ferrule 106.

It should be further noted that, in the embodiment of the present application, only the case where the sleeve resets the crown shaft when no longer being stressed is taken as an example, but the present application is not limited to this, and in the embodiment of the present application, the crown shaft may also be reset when no longer being stressed by another structure/device, for example, the crown shaft may be reset by a spring structure.
