[0002] With the technological development of electronic devices, there are more and more types of electronic devices. In an example in which an electronic device is a smartwatch, when a user uses the smartwatch, in order to save power, the existing smartwatch usually has a function of controlling a display screen to be on and off based on a motion state of a wrist of the user. Generally, the display screen of the smartwatch needs to be on when the wrist of the user is raised, and the display screen is off when the wrist of the user is lowered. This function can be implemented by determining a motion direction of the smartwatch by the smartwatch.

[0003] However, in the related art, there is a decision error of the electronic device in determining whether the display screen is turned on or turned off, thereby reducing efficiency in using the portable electronic device by the user.

DESCRIPTION OF EMBODIMENTS

[0016] The following clearly and completely describes the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application.

[0017] In the specification and claims of this application, the terms "first", "second", and the like are intended to distinguish between similar objects but do not describe a specific order or sequence. It should be understood that, data used in such a way are interchangeable in proper circumstances, so that the embodiments of this application can be implemented in an order other than the order illustrated or described herein. Objects classified by "first", "second", and the like are usually of a same type, and the number of objects is not limited. For example, there may be one or more first objects. In addition, in the specification and the claims, "and / or" represents at least one of connected objects, and a character " / " generally represents an "or" relationship between associated objects.

[0018] The term "centripetal force parameter" in the embodiments of this application is explained as follows: Centripetal force is resultant force directed toward a center of a circle (a center of curvature) as an object moves along a circumference or a curved track. The term "centripetal force" is named from an effect produced by this resultant force action, and this effect may be produced by any force such as elastic force, gravity force, or friction force or may be provided by resultant force of several types of force or a component thereof.

[0019] Because a circular motion belongs to a curvilinear motion, the object in the circular motion is also subjected to resultant force having different velocity directions. The centripetal force is tension for the object in the circular motion, and a direction of the centripetal force constantly changes as the object moves on the curved track. This tension is directed toward a center of the circumference along a circumferential radius, and therefore is named as the "centripetal force". The centripetal force is directed toward the center of the circumference, and the object controlled by the centripetal force moves in a tangential direction.

[0020] A magnitude of the centripetal force is closely related to a mass (m) of the object, a length (r) of the circumferential radius for movement of the object, and an angular velocity (ω).

[0021] The centripetal force parameter in the embodiments of this application may include a direction parameter of the centripetal force.

[0022] With reference to the accompanying drawings, a screen control method provided in the embodiments of this application is described in detail by using specific embodiments and application scenes.

[0023] The screen control method provided in the embodiments of this application may be used in a scene containing a detectable centripetal force parameter when a user wears an electronic device during motion.

[0024] For the scene containing the detectable centripetal force parameter when the user wears the electronic device during motion, functions and types of existing electronic devices are increasing. In an example in which the electronic device is a smartwatch, when the user wears the smartwatch, in order to save power, the existing smartwatch usually has a function of controlling a display screen to be on and off based on a motion state of a wrist of the user. Generally, the display screen of the smartwatch needs to be on when the wrist of the user is raised, and the display screen is off when the wrist of the user is lowered. This function can be implemented by determining a motion direction of the smartwatch by the smartwatch.

[0025] However, when the electronic device is at different positions, it is determined that motion directions of the display screen are different in on and off states. For example, when the smartwatch is worn on a left hand and a right hand, it is determined that the motion directions of the display screen are exactly opposite in the on and off states. Therefore, in a case that an accurate wearing position of the electronic device cannot be accurately determined, there is a decision error of the electronic device in determining whether the display screen is turned on or turned off, thereby reducing efficiency in using the electronic device by the user.

[0026] In this embodiment of this application, in a case that a user wears an electronic device, the electronic device first detects a first motion parameter of the electronic device, and then determines, based on the detected first motion parameter, a wearing position of a user wearing the electronic device. After the wearing position is determined, a screen of the electronic device is turned on in a case that the wearing position is a first position and a second motion parameter of the electronic device meets a first preset condition; or the screen of the electronic device is turned off in a case that the wearing position is the first position and the second motion parameter of the electronic device meets a second preset condition, where the first preset condition and the second preset condition respectively match the first position. In this way, the first motion parameter of the electronic device is detected, so that the wearing position of the user wearing the electronic device can be accurately determined. Therefore, a screen-on operation and a screen-off operation can be accurately determined when the user raises a wrist to view the electronic device, and the user can view content displayed on a display screen of the electronic device, thereby improving efficiency of using the electronic device by the user.

[0027] This embodiment provides a screen control method. As shown in FIG. 1, this embodiment is applied to an electronic device. The screen control method includes step 301 to step 303.

[0028] Step 301: A screen control apparatus detects a first motion parameter of the electronic device.

[0029] In this embodiment of this application, the electronic device may be a portable electronic device, and the portable electronic device may be a portable smartwatch or another wearable smart electronic device. This is not limited in this embodiment of this application.

[0030] In this embodiment of this application, the screen control apparatus may continuously detect the first motion parameter of the electronic device, or may periodically detect the first motion parameter of the electronic device.

[0031] In this embodiment of this application, the first motion parameter is a parameter for determining a wearing position of the electronic device in a parameter corresponding to a current motion state of the electronic device.

[0032] In an example, the first motion parameter may include a direction parameter, a velocity parameter, and the like. Generally, an acceleration parameter and a direction parameter of centripetal force may be included. This is not limited in this embodiment of this application.

[0033] In this embodiment of this application, the electronic device may detect the first motion parameter by using a motion state detection device inside the electronic device.

[0034] In an example, the electronic device may detect the first motion parameter by using a built-in gyroscope (gyro) and an acceleration sensor (acceleration sensor, acc). For example, a motion direction and a motion speed of the smartwatch are detected by using the built-in gyroscope.

[0035] It should be noted that in this embodiment of this application, the motion state of the electronic device may be a motion state on a stable plane, for example, an X-Y axis plane. It may be understood that the foregoing plane may be a relative planes such as a plane conforming to two axes (for example, a plane in any direction composed of two axes relative to 90°), and is not necessarily an absolute plane such as an absolute horizontal plane. In an example, the motion state on the stable plane may be a translational motion on any two-axis plane. For example, when the two-axis plane is an X-Y axis plane, the motion state may be a translational rotational motion of the electronic device on the X-Y axis plane.

[0036] Step 302: The screen control apparatus determines a wearing position of the electronic device based on the first motion parameter.

[0037] In this embodiment of this application, when the electronic device is worn at different positions, the electronic device corresponds to different first motion parameters. The electronic device may prestore a correspondence between a first motion parameters and a wearing position in the electronic device, or a user may customize the correspondence between a first motion parameters and a wearing position. This is not limited in this embodiment of this application.

[0038] It should be noted that when the electronic device is a device worn by the user, this embodiment of this application may be performed in a case that the electronic device does not set the wearing position or it is detected that the user removes the electronic device and the wearing position needs to be reset. After the wearing position is determined, if no change of the wearing position by the electronic device is detected, the determined result may be continuously used as the default wearing position, or steps 301 and 302 may be repeatedly performed by using the first motion parameter, and the first motion parameter is continuously detected and the accurate wearing position is determined. This is not limited in this embodiment of this application.

[0039] Step 303: The screen control apparatus turns on a screen of the electronic device in a case that the wearing position is a first position and a second motion parameter of the electronic device meets a first preset condition; or turns off the screen of the electronic device in a case that the wearing position is the first position and the second motion parameter of the electronic device meets a second preset condition.

[0040] In this embodiment of this application, the first preset condition matches the first position, and the second preset condition matches the first position.

[0041] In this embodiment of this application, the first position may be an example wearing position of the electronic device. For example, the user wears the electronic device on a left wrist and the left wrist is the first position.

[0042] In this embodiment of this application, the second motion parameter is a motion parameter for determining whether the electronic device is in a screen-on state or a screen-off state in a case that the wearing position of the electronic device is the first position. For example, assuming that the first position is the left wrist, the second motion parameter is a motion parameter of a motion process in which the user raises the wrist to the front, or a motion parameter of a motion process in which the user lowers the wrist.

[0043] In this embodiment of this application, the first preset condition is a condition corresponding to a case that the second motion parameter may meet a screen-on condition, and the second preset condition is a condition corresponding to a case that the second motion parameter may meet a screen-off condition.

[0044] In this embodiment of this application, the first preset condition and the second preset condition may be preset thresholds of different region ranges. The preset threshold may be preset by the electronic device, or may be defined by the user. This is not limited in this embodiment of this application.

[0045] It may be understood that the first preset condition and the second preset condition may be a same type of representation as the second motion parameter. For example, when the second motion parameter is an angle parameter, the first preset condition and the second preset condition may be respectively angle parameter ranges corresponding to a screen-on state and a screen-off state. Alternatively, the first preset condition and the second preset condition may be different types of representation from the second motion parameter. For example, when the second motion parameter is an angle parameter, the first preset condition and the second preset condition are respectively direction parameters corresponding to a screen-on state and a screen-off state. When obtaining the angle parameter, the electronic device may convert the angle parameter into a direction parameter, and compare the direction parameter with the first preset condition and the second preset condition, thereby determining a screen-on state and a screen-off state.

[0046] In an example, the second motion parameter may be a Z-axis rotation direction parameter when the electronic device moves. Generally, the electronic device may determine the Z-axis rotation direction parameter by using a gyroscope. The first preset condition may be a parameter range of a Z-axis rotation direction parameter corresponding to a screen-on state when the electronic device is worn at different positions, and the second preset condition may be a parameter range of a Z-axis rotation direction parameter corresponding to a screen-off state when the electronic device is worn at different positions.

[0047] For example, when the electronic device is a smartwatch, and it is determined that the smartwatch is worn on the left wrist of the user (that is, the first position), if the gyroscope of the electronic device learns that the electronic device rotates clockwise along a Z-axis rotation direction (that is, the first preset condition), the screen is turned on, and if the gyroscope of the electronic device learns that the electronic device rotates counterclockwise along the Z-axis rotation direction (that is, the second preset condition), the screen is turned off.

[0048] According to the screen control method provided in this embodiment of this application, a screen control apparatus first detects a first motion parameter of the electronic device, and then determines, based on the detected first motion parameter, a wearing position of a user wearing the electronic device. After the wearing position is determined, a screen of the electronic device is turned on in a case that the wearing position is a first position and a second motion parameter of the electronic device meets a first preset condition; or the screen of the electronic device is turned off in a case that the wearing position is the first position and the second motion parameter of the electronic device meets a second preset condition, where the first preset condition and the second preset condition respectively match the first position. In this way, the first motion parameter of the electronic device is detected, so that the wearing position of the user wearing the electronic device can be accurately determined. Therefore, a screen-on operation and a screen-off operation can be accurately determined when the user raises a wrist to view the electronic device, and the user can view content displayed on a display screen of the electronic device, thereby improving efficiency of using the electronic device by the user.

[0049] Optionally, in this embodiment of this application, in step 302 of determining a wearing position of the electronic device based on the first motion parameter, the screen control method provided in this embodiment of this application may include the following step A: Step A: In a case that the first motion parameter includes a centripetal force parameter of the electronic device moving along a curved track, the screen control apparatus determines, based on the first motion parameter, a wearing position of a user wearing the electronic device.

[0050] In this embodiment of this application, the curved track is a motion track when the electronic device moves.

[0051] In an example, in a case that the electronic device is worn at a wrist, the motion track may include a circular motion with an elbow joint as a center, and the curved track may be a curved track of the circular motion with the elbow joint as the center.

[0052] In this embodiment of this application, for the centripetal force parameter, refer to the foregoing descriptions. Details are not described herein again.

[0053] In this embodiment of this application, when the centripetal force parameter includes a centripetal force direction and a centripetal acceleration, different centripetal force directions and centripetal accelerations may indicate centripetal force parameters of different motions of the electronic device, and correspond to different wearing positions.

[0054] In an example, when the wearing position of the electronic device is a wrist, a circular motion in which the electronic device is worn on a left wrist corresponds to a circular motion in which the electronic device is worn on a right wrist. Generally, in a process of the circular motion of the left wrist or the right wrist, static friction force is generated between the electronic device and the wrist, and a centripetal force parameter corresponding to the static friction force is generated. Since a motion direction of the circular motion on the left wrist is opposite to that on the right wrist, the accurate wearing position of the electronic device may be determined based on a change of centripetal force directions and centripetal accelerations of different centripetal force parameters corresponding to different circular motions.

[0055] Optionally, in this embodiment of this application, in step 302 of determining, based on the first motion parameter, a wearing position of a user wearing the electronic device, the screen control method provided in this embodiment of this application may include the following step B1 and step B2: Step B1: In a case that the first motion parameter meets a third preset condition, the screen control apparatus determines that the electronic device is worn on a left hand of the user. Step B2: In a case that the first motion parameter meets a fourth preset condition, the screen control apparatus determines that the electronic device is worn on a right hand of the user.

[0056] Optionally, in this embodiment of this application, the centripetal force parameter further includes a first centripetal force parameter in a first direction and a second centripetal force parameter in a second direction.

[0057] For example, the first direction and the second direction are two directions perpendicular to each other on a plane in which a display screen of the electronic device is located.

[0058] For example, the third preset condition is that the first centripetal force parameter changes from a negative value to a positive value, and the centripetal force parameter in the second direction changes from a positive value to a negative value; and the fourth preset condition is that the first centripetal force parameter changes from a positive value to a negative value, and the second centripetal force parameter changes from a negative value to a positive value.

[0059] For example, the third preset condition and the fourth preset condition may be pre-stored in the electronic device by the electronic device, or may be customized by the user. This is not limited in this embodiment of this application.

[0060] For example, the third preset condition may be a correspondence between a first motion parameter and a wearing position when the electronic device is worn on the left hand. Similarly, the fourth preset condition may be a correspondence between a first motion parameter and a wearing position when the electronic device is worn on the right hand.

[0061] For example, the first direction and the second direction may be two axes of the two-axis plane, and directions of the two axes may be respectively the first direction and the second direction.

[0062] Example 1: Assuming that the electronic device is a smartwatch, and the first motion parameter is an acceleration and a centripetal force parameter, in a case that the user wears the smartwatch on the left wrist and the left hand is placed at rest on a desktop to continuously operate a computer mouse, the smartwatch automatically continuously detects a first motion parameter of the smartwatch. As shown in FIG. 2a and FIG. 2b, FIG. 2a is a fluctuation diagram of a change in a centripetal acceleration, and FIG. 2b is a fluctuation diagram of a change in a centripetal angular velocity. As shown in the figure, before a time point 9.5s, an acc sensor and a gyro of the smartwatch detect that a centripetal acceleration and a centripetal angular velocity of the smartwatch in X, Y, and Z axes fluctuate around 0 until a time period before and after 9.5s. In this time period, if a right arm of the user rotates counterclockwise with an elbow joint as an axis along a curved track of the circumference through a circular motion to move the wrist to the front, the acc detects that a centripetal acceleration in the Z axis fluctuates and a centripetal acceleration in the X axis is a negative value, and correspondingly, at the wrist, the smartwatch is directed toward a humerus from the wrist, and a centripetal acceleration in the Y axis changes from a negative value to a positive value, that is, the smartwatch is first subjected to thrust and then to tension, and the gyro detects that a centripetal angular velocity in the Z axis suddenly changes to -400 degrees / second and then rapidly changes to 0 degrees / second, and the centripetal angular velocity is a negative value. It may be learned from this centripetal angular velocity that the smartwatch rotates clockwise.

[0063] In a time period before and after 12.5s, if a left arm of the user rotates the wrist clockwise to the mouse with an elbow joint as an axis along a curved track of the circumference through a circular motion, the acc detects that a centripetal acceleration in the Z axis fluctuates, a centripetal acceleration in the X axis is a negative value, and a centripetal acceleration in the Y axis changes from a positive value to a negative value, that is, the smartwatch is subjected to tension and then to thrust, and the gyro detects that a centripetal angular velocity in the Z axis suddenly changes to 400 degrees / second and then rapidly increases to 0 degrees / second, and the centripetal angular velocity is a positive value. It may be comprehensively determined, based on the centripetal acceleration and the angular velocity, that the smartwatch rotates counterclockwise.

[0064] Through the above two changes of the first motion parameter, based on the preset correspondence between a first motion parameter and a wearing position (that is, the first motion parameter meets the first preset condition), it may be determined that the smartwatch is worn on the left hand.

[0065] After it is determined that the smartwatch is worn on the left hand, when the gyro detects that a rotation direction of the electronic device along the Z axis (that is, the second motion parameter) is clockwise rotation (that is, the first preset condition), the screen is turned on, or if the gyro of the smartwatch detects that the rotation direction of the smartwatch along the Z axis (that is, the second motion parameter) is counterclockwise rotation (that is, the second preset condition), the screen is turned off.

[0066] Example 2: Assuming that the electronic device is a smartwatch, and the first motion parameter is an acceleration and a centripetal force parameter, in a case that the user wears the smartwatch on the right wrist and the right hand is placed at rest on a desktop to continuously operate a computer mouse, the smartwatch automatically continuously detects a first motion parameter of the smartwatch. As shown in FIG. 3a and FIG. 3b, FIG. 3a is a fluctuation diagram of a change in a centripetal acceleration, and FIG. 3b is a fluctuation diagram of a change in a centripetal angular velocity. Before a time point 84s, an acc sensor and a gyro of the smartwatch detect that a centripetal acceleration and a centripetal angular velocity of the smartwatch in X, Y, and Z axes fluctuate around 0 until a time period before and after 84s. In this time period, if a right arm of the user rotates counterclockwise with an elbow joint as an axis along a curved track of the circumference through a circular motion to move the wrist to the front, the acc detects that a centripetal acceleration in the Z axis fluctuates and a centripetal acceleration in the X axis is a positive value, and correspondingly, at the wrist, the smartwatch is directed toward a humerus from the wrist, and an acceleration in the Y axis changes from a negative value to a positive value, that is, the smartwatch is first subjected to thrust and then to tension, and the gyro detects that a centripetal angular velocity in the Z axis suddenly changes to 300 degrees / second and then rapidly reduces to 0 degrees / second, and the centripetal angular velocity is a positive value. It may be learned from this centripetal angular velocity that the smartwatch rotates counterclockwise.

[0067] In a time period before and after 90s, if a right arm of the user rotates the wrist clockwise to the mouse with an elbow joint as an axis along a curved track of the circumference through a circular motion, the acc detects that a centripetal acceleration in the Z axis fluctuates, a centripetal acceleration in the X axis is a positive value, and a centripetal acceleration in the Y axis changes from a positive value to a negative value, that is, the smartwatch is subjected to thrust and then to tension, and the gyro detects that a centripetal angular velocity in the Z axis suddenly increases to -300 degrees / second and then rapidly increases to 0 degrees / second, and the centripetal angular velocity is a negative value. It may be comprehensively determined, based on the centripetal acceleration and the angular velocity, that the smartwatch rotates clockwise.

[0068] Through the above two changes of the first motion parameter, based on the preset correspondence between a first motion parameter and a wearing position (that is, the first motion parameter meets the second preset condition), it may be determined that the smartwatch is worn on the right hand.

[0069] After it is determined that the smartwatch is worn on the right hand, when the gyro detects that a rotation direction of the electronic device along the Z axis is counterclockwise rotation (that is, the first preset condition), the screen is turned on, or if the gyro of the smartwatch detects that the rotation direction of the smartwatch along the Z axis is clockwise rotation (that is, the second preset condition), the screen is turned off.

[0070] It may be understood that in the foregoing example 1 and example 2, because the two hand operations of the user are stationary, the thrust and the tension are approximately equal to each other in opposite directions. For example, an integral area of the acceleration sensor acc in a positive direction in the Y axis is equal to an integral area in a negative direction. However, there is no positive-negative cancellation of the acceleration sensor in the X axis. Therefore, there is no combination of the thrust and the tension, and only static friction is used as centripetal force. In an example, sliding friction may be used as centripetal force in a case that there is a relative motion between a dial of the smartwatch and the hand.

[0071] In this way, the electronic device may accurately determine based on a preset condition and the obtained first motion parameter, that the electronic device is worn on the left hand or the right hand, and further, the electronic device may accurately determine a moment at which the user needs to view and turn on or turn off the screen, thereby reducing resource consumption of the electronic device.

[0072] Optionally, in this embodiment of this application, after step 302 of determining a wearing position of the electronic device based on the first motion parameter, the screen control method provided in this embodiment of this application further includes the following step C: Step C: The screen control apparatus re-determines the wearing position of the electronic device in a case that an obstacle is detected in a predetermined region at a position at which the electronic device is located.

[0073] For example, the electronic device may detect a shielding object by using a sensor. For example, the electronic device may detect the shielding object by using an infrared sensor, or may detect the shielding object by using a capacitive touch sensor.

[0074] For example, the predetermined region may be preset by the electronic device or may be customized by the user.

[0075] For example, the screen control apparatus may re-determine the wearing position of the electronic device by redetecting the first motion parameter of the electronic device.

[0076] For example, the predetermined region may be determined based on a condition of redetecting the first motion parameter of the electronic device.

[0077] In an example, when the condition for redetecting the first motion parameter of the electronic device is that the user removes the electronic device, the predetermined region may be set on the back of the electronic device, and in a case that the electronic device is disconnected from the user, the electronic device may sense, through the sensor, that the back of the electronic device changes from being shielded to unshielded, and further perform step 301 and step 302, redetect the first motion parameter of the electronic device, and further re-determine the wearing position of the electronic device.

[0078] In this way, the electronic device may redetect the first motion parameter of the electronic device in a specific case, and then re-determine the wearing position. Therefore, in a case that the wearing position is accurately determined, the first motion parameter does not need to be continuously detected, so that resource consumption of the electronic device can be reduced.

[0079] Optionally, in this embodiment of this application, in step 301, the screen control method provided in this embodiment of this application may include the following step D: Step D: The screen control apparatus detects the first motion parameter of the electronic device in a case that the electronic device is in a preset motion state in a third direction.

[0080] For example, the third direction is a direction perpendicular to the plane in which the display screen of the electronic device is located.

[0081] For example, the preset motion state may be that the first motion parameter in the third direction exceeds a preset threshold.

[0082] It may be understood that when the electronic device is in a stable state on the two-axis plane (that is, in a case that there is no centripetal force parameter exceeding the preset threshold, for example, an arm is placed at rest on the two-axis plane), the electronic device does not have the centripetal force parameter. In a case that the first motion parameter of the electronic device in the third direction reaches the preset threshold, the electronic device may determine that the electronic device has the centripetal force parameter, and may determine the wearing position of the portable electronic device by detecting the first motion parameter.

[0083] In an example, the first motion parameter in the third direction may be a first motion parameter for a circular motion around the third direction in a plane in which the first direction and the second direction lie. The first motion parameter may include centripetal force parameters in the first direction, the second direction, and the third direction, and the centripetal force parameter may include a centripetal angular velocity and a centripetal acceleration.

[0084] Example 3: For example, the electronic device is a smartwatch, the first direction is an X axis, the second direction is a Y axis, and the third direction is a Z axis. In a case that the smartwatch is stationary on an X-Y plane and circumferentially moves around the Z axis, a motion amplitude is less than a preset threshold.
