Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In the description that follows, the terms "first," "second," and the like are used for descriptive purposes only and are not intended to indicate or imply relative importance nor order to be construed.
Along with the development of science and technology, intelligent household equipment is more and more. For smart home devices with small sizes, users often forget the placement position of the devices when using the smart home devices. Generally, a user is required to self-recall the placement position of the device, and the efficiency of forgetting to find the device is low.
To overcome the problems in the related art to some extent, the present disclosure provides a display control method, a display control apparatus, a storage medium, and a terminal.
Hereinafter, a display control method, a display control apparatus, a terminal, and a storage medium according to embodiments of the present invention will be described with reference to the drawings.
Fig. 1 is a flowchart illustrating a display control method according to an exemplary embodiment, which is applied to a first electronic device, where the first electronic device may be an electronic device such as a smart terminal with a display screen, a smart tablet, a smart wearable device, a personal electronic commerce assistant, and a personal computer.
As shown in fig. 1, the method comprises the steps of:
in step S101, in response to receiving a control instruction, controlling the first electronic device to start a screen display function;
in step S102, in case that the control instruction satisfies a preset condition, displaying location information of at least one second electronic device on a screen.
When a control instruction is received, the first electronic device can be in a dormant state or a power-off state, and the first electronic device is controlled to start a screen display function in response to the received control instruction. The control instruction can carry awakening indication information, so that the first electronic equipment enters an awakening or starting state according to the control instruction, and a screen display function is started. The control command may be a specific type of command, for example, an infrared signal command, a bluetooth signal command, or another type of command, for example, a voice signal command input through a voice signal or a gesture command input through a gesture echo signal, and the like. The present disclosure is not limited to the type and input method of the control command, and may be set as needed.
After the first electronic device receives the control instruction, whether the control instruction meets the preset condition or not can be judged, and under the condition that the control instruction meets the preset condition, the position information of at least one second electronic device is displayed on the screen.
The preset condition can be set according to the requirement, and can be set as any one or more of the following conditions: the instruction type corresponding to the control instruction is matched with the preset instruction type, and the identification of the sending equipment corresponding to the control instruction is matched with the identification of the preset equipment. In this way, when the first electronic device receives the control instruction, the operation of displaying the position information of at least one second electronic device on the screen is executed under the condition that the control instruction is determined to meet the preset condition. For example, when the preset instruction type is an infrared instruction type or a bluetooth instruction type, the first electronic device determines whether the instruction type of the received control instruction is an infrared instruction type or a bluetooth instruction type, and when the instruction type of the control instruction is an infrared or bluetooth instruction, performs an operation of displaying the position information of at least one second electronic device on the screen; or the first electronic equipment judges whether the second electronic equipment which sends the instruction and corresponds to the received control instruction is the preset equipment or not, and when the identification of the sending equipment which corresponds to the control instruction is matched with the identification of the preset equipment, the operation of displaying the position information of at least one second electronic equipment on the screen is executed. The sending device is an electronic device capable of controlling the first electronic device to start the screen display function, the second electronic device is an electronic device except the first electronic device, and the sending device and the second electronic device can be electronic devices such as an intelligent terminal, an intelligent tablet, an intelligent wearable device, a personal electronic commerce assistant and a personal computer.
In the intelligent home environment, the quantity of intelligent equipment is more and more, and to the less intelligent equipment of volume, the user often forgets the place of this equipment when using. Taking the first electronic device as an example of a television device, a remote control device for controlling the television device may be difficult to find due to its small size. In order to improve the efficiency of searching for forgotten equipment for a user, the scheme may send a control instruction to the television equipment through the sending equipment, so that the television equipment starts a screen display function, and when the television equipment determines that the control instruction meets a preset condition, for example, when the television equipment determines that an identifier of the sending equipment corresponding to the control instruction matches an identifier of predetermined equipment, the position information of at least one second electronic equipment is displayed on the screen, for example, the position information of the remote control equipment is displayed, so that the user can conveniently determine the position of the remote control equipment through a large screen of the television equipment and further search.
The display control method provided by the embodiment of the disclosure responds to the fact that a first electronic device receives a control instruction, and controls the first electronic device to start a screen display function; under the condition that the control instruction meets a preset condition, displaying the position information of at least one second electronic device on a screen; therefore, under the condition that the control instruction meets the preset condition, the first electronic device is controlled to display the position information of at least one second electronic device, the position information of the second electronic device is visualized, the second electronic device can be conveniently found according to the display content, and the efficiency of finding the device by a user is improved.
In some possible embodiments, the controlling the first electronic device to start the screen display function in response to receiving the control instruction includes:
detecting awakening indication information carried by the control instruction;
and controlling the first electronic equipment to start a screen display function based on the awakening indication information.
When the control instruction is received, the first electronic device may be in an un-awakened state, for example, in a sleep or power-off state, and accordingly, the screen display function of the first electronic device may be in an un-activated state or in an incompletely activated state at this time. The control instruction can carry awakening indication information, so that the first electronic equipment enters an awakening or starting state according to the control instruction, and a screen display function is started. Therefore, when the first electronic device responds to the received control instruction, whether the control instruction carries the awakening indication information or not can be detected, and under the condition that the control instruction carries the awakening indication information, the first electronic device is controlled to start the screen display function based on the awakening indication information. In this way, the first electronic device starts the screen display function only when the received control instruction carries the wakeup indication information. The first electronic device can keep a low power consumption state under the condition that the control instruction carrying the awakening indication information is not received, and meanwhile, the problem that the first electronic device carries out false response on an invalid control instruction can be avoided.
The screen display functionality may include an off-screen display mode and a full-screen display mode. An off-screen Display (AOD) is a Display function of an electronic device, and after the off-screen Display is enabled, a part of a screen of the electronic device remains in an activated state in a standby state, so that limited information can be displayed when the electronic device is in the standby state. For example, information such as time, date, and battery status is displayed by default; the system can also be configured by a user to remind when a notice comes, or continuously run a screen saver.
The first electronic device can enter a screen-off display mode or a full-screen display mode when the screen display function is started in response to the received control instruction. The specific entering of the screen-off display mode or the full-screen display mode by the first electronic device starting the screen display function can be determined by the instruction content carried by the control instruction. For example: the control instruction carries instruction content for instructing the first electronic device to enter a screen-off display mode, and the first electronic device starts a screen display function to enter the screen-off display mode in response to receiving the control instruction.
It should be noted that, no matter the first electronic device enters the screen-off display mode or the full-screen display mode according to the control instruction, after the screen display function is started, the first electronic device may further switch the display mode according to a subsequently received control instruction or according to whether the control instruction satisfies a preset condition, for example, after the first electronic device enters the screen-off display mode according to the control instruction, the display mode may also be switched to the full-screen display mode according to the subsequently received control instruction or according to whether the control instruction satisfies the preset condition, or the screen-off display mode may also be maintained, and specific contents will be described in the following embodiments.
In some possible embodiments, the preset conditions include at least one or more of the following:
the instruction type corresponding to the control instruction is matched with a preset instruction type;
and the identification of the sending equipment corresponding to the control instruction is matched with the identification of the preset equipment.
The preset instruction type may be preset as needed, for example, the preset instruction type may be set to be one or more of an infrared instruction type, a bluetooth instruction type, a voice instruction type, or a gesture instruction type, and the disclosure does not limit a specific setting manner of the preset instruction type. When the first electronic device responds to the received control instruction, it may be determined whether the control instruction is a preset instruction type, for example, whether the control instruction is an infrared instruction type or a gesture instruction type, and when the instruction type is the preset instruction type, the position information of the at least one second electronic device is displayed on the screen.
Similarly, the predetermined device may also be preset as needed, taking the first electronic device as a television as an example, for example, the predetermined device may be set as any device capable of controlling the television device, store the identifier of the device in the television device, when the television receives the control instruction, first determine whether the identifier of the sending device corresponding to the control instruction matches with the identifier of the predetermined device, and when the two match, display the location information of at least one second electronic device on the screen.
Taking the first electronic device as an example of a television device, a remote control device for controlling the television device may be difficult to find due to its small size. A preset instruction type can be set in advance according to the type of the remote control device, for example, the remote control device is an infrared remote controller, and the preset instruction type can be set as an infrared instruction type; the remote control equipment is a Bluetooth remote controller, and the preset instruction type can be set as a Bluetooth instruction type; the remote control equipment is an infrared Bluetooth remote controller, and the preset instruction type can be set to be an infrared instruction type and a Bluetooth instruction type. When the user cannot find the infrared remote controller, the control instruction can be sent to the television equipment through other sending equipment capable of sending the infrared instruction, so that the television equipment starts a screen display function. When the television device judges that the instruction type corresponding to the control instruction is matched with the preset instruction type, namely the infrared instruction type, the position information of at least one second electronic device can be displayed on the screen of the television device.
Still taking the first electronic device as an example for a television device, a remote control device for controlling the television device may be difficult to find due to its small size. The identifier of the predetermined device may also be set in advance according to the identifier of the remote control device, for example, the remote control device is an infrared remote controller, the predetermined device may be set as all devices, except the infrared remote controller, which are registered in advance with the television device in the smart home environment, and the device identifiers of all devices, except the infrared remote controller, may be acquired and stored in the local television device or in the electronic device associated with the television device. When the user cannot find the infrared remote controller, a control instruction can be sent to the television equipment through other second electronic equipment, so that the television equipment starts a screen display function. When the television device judges that the identifier of the second electronic device corresponding to the control instruction is matched with the identifier of the preset device, the position information of at least one second electronic device can be displayed on the screen of the television device.
The above two embodiments are only used to describe how to display the location information of the at least one second electronic device on the screen according to whether the control instruction satisfies the preset condition, and the present solution is not limited to be implemented only by the above two ways.
In addition, the preset condition may also include the above two conditions, that is, the instruction type corresponding to the control instruction matches the preset instruction type, and the identifier of the sending device corresponding to the control instruction matches the identifier of the predetermined device. When the first electronic device judges whether the control instruction meets the preset condition, it may be judged whether the control instruction type matches the preset instruction type, and then, it is judged whether the identifier of the sending device corresponding to the control instruction matches the identifier of the predetermined device under the condition that the instruction type matches, and only when both are matched, the position information of at least one second electronic device is displayed on the screen. Of course, the determination sequence of whether the first electronic device determines that the preset condition is satisfied may also be set as required, which is not limited by this disclosure.
In some possible embodiments, in the case that the control instruction satisfies a preset condition, displaying location information of at least one second electronic device on a screen includes:
under the condition that the control instruction meets a preset condition, displaying position information of at least one second electronic device in a preset area on a screen;
wherein the position information at least comprises any one or more of the following:
distance information between the second electronic device and the first electronic device;
orientation information between the second electronic device and the first electronic device.
Fig. 2 is a schematic diagram illustrating a display control method according to an exemplary embodiment of the present disclosure.
Referring to fig. 2, the display control method is applied to a first electronic device, taking the first electronic device as a television as an example, and when a control instruction meets a predetermined condition, displaying location information of at least one second electronic device in a predetermined area on a screen. The specific predetermined area on the screen of the first electronic device displays the location information of which second electronic device or devices can be set as required, which is not limited by the present disclosure.
The second electronic device is an electronic device other than the first electronic device, and may be the transmitting device as mentioned in the above embodiments, or may be an electronic device other than the transmitting device and the first electronic device. In some possible embodiments, the sending device and the second electronic device corresponding to the control instruction may each include multiple devices, and the sending device and the second electronic device may be the same or different. The association relationship between the sending device that sends the control instruction and the second electronic device that subsequently displays the position information may be set in advance, and the first electronic device may determine the second electronic device that subsequently displays the position information according to the sending device that sends the control instruction and the association relationship. When the association relationship between the transmitting device for transmitting the control instruction and the second electronic device for subsequently displaying the location information is not preset, the first electronic device may display the location information of all the second electronic devices UWB-registered with the first electronic device by default on the screen, so that the user can determine the location of the second electronic device according to his or her needs.
For example, when the first electronic device is a television device, the remote controller is an intelligent device in a standard configuration for controlling the television device, and an identifier of a predetermined device may be set in advance according to the identifier of the remote controller, and the predetermined device is set as all devices, except for the remote controller, registered with the television device in advance in the smart home environment. The method comprises the steps that the association relationship between sending equipment for sending a control instruction and a remote controller for displaying position information subsequently is set to be a complementary relationship in advance, when a user cannot find the remote controller, the sending equipment can send the control instruction to the television equipment, when the television equipment receives the control instruction, the fact that the sender of the control instruction is not the remote controller can be known, the corresponding situation is that the user cannot find the remote controller, and the position of the remote controller to be displayed is determined according to the sending equipment for sending the control instruction and the association relationship, so that after the television equipment judges that the control instruction meets the preset condition, the position information of the remote controller can be displayed on a screen so that the user can find the position information. In addition, the first electronic device is controlled to display the location information of at least one second electronic device in a predetermined area on the screen, the location information may be displayed in an off-screen display mode or a full-screen display mode, specifically, which mode to display may be determined according to the number of the second electronic devices that need to be displayed, or may be determined according to the indication content carried in the control instruction, which is not limited by the present disclosure.
For example, when the first electronic device starts the screen display function in the screen-off display mode, if only the position information of the second electronic device needs to be displayed, the screen display function can be displayed in the current screen-off display mode; if the position information of the plurality of second electronic devices needs to be displayed, the screen-off display mode can be switched to the full-screen display mode for displaying according to the number of the second electronic devices needing to be displayed.
The predetermined area on the screen of the first electronic device may be a partial area or a whole area of the bright screen area in the screen display mode in which the first electronic device is currently located. When the first electronic device displays the position information of at least one second electronic device on the screen, the display duration of the position information can be preset. The size or/and the display duration of the specific predetermined area can be set as required. For example, the predetermined area may be an area in a lower left corner in a bright screen range of a display screen of the first electronic device; the first predetermined time period may be a preset fixed time period or a preset time period interval.
The location information may comprise distance information of the second electronic device from the first electronic device and/or orientation information of the predetermined device from the first electronic device. The specific display form of the distance information and the orientation information may be set as needed.
Referring to fig. 2, the first electronic device is a television device a, and when the television device a controls the television device a to start a screen display function in response to receiving a control instruction, under the condition that it is determined that the control instruction satisfies a preset condition, the second electronic devices that can determine subsequent display position information according to a sending device that sends the control instruction and the association relationship are a remote control device B and a bracelet device C.

Fig. 4 is a flowchart illustrating another display control method according to an example embodiment.
Referring to fig. 4, in some possible embodiments, before displaying the location information of the at least one second electronic device on the screen, the method includes:
in step S401, controlling the UWB radar ranging module of the first electronic device to transmit a pulse positioning signal;
in step S402, receiving a first positioning echo signal sent by a UWB positioning tag of at least one second electronic device within a first predetermined range of the first electronic device;
in step S403, position information of the second electronic device corresponding to the positioning echo signal relative to the first electronic device is determined according to the receiving time of the first positioning echo signal.
UWB is a short-range wireless carrier communication technology, which transmits data by transmitting and receiving extremely narrow pulses having nanosecond or less, without using sinusoidal carriers in the conventional communication system, thereby having a bandwidth in the order of GHz. The method solves the major problems of the traditional wireless communication technology in the aspect of propagation for many years, and has the advantages of high data transmission rate, low power consumption, low cost, strong penetration capacity, good multipath resistance effect, high safety and the like. The ultra-wideband UWB radar ranging module is used for indoor positioning, can sense a terminal which is provided with the ultra-wideband UWB positioning module nearby, and accurately judges the position relation of each other, and is accurate in positioning and high in precision.
Here, the first electronic device may send UWB pulse location signals through the UWB radar ranging module, for example: pulse signals with a width greater than 500MHz or a ratio of baseband bandwidth to carrier frequency greater than 0.2. The UWB radar ranging module of the first electronic device may send the pulse positioning signal, and receive a positioning echo signal sent by a UWB positioning tag included in at least one second electronic device within a first predetermined range of the first electronic device, thereby determining an angle and a position of the second electronic device carrying the UWB positioning tag at an opposite end. The transmission direction of the pulse positioning signal can be represented by the incident angle of the received positioning echo signal (i.e. the angle between the signal source and the normal), so as to determine the azimuth angle of the first electronic device and the second electronic device. The specific arrangement of the normal and the azimuth has been described in the foregoing embodiments, and will not be described herein.
In some possible embodiments, the UWB radar ranging module of the first electronic device may include at least 2 sets of antenna arrays, each set of antenna arrays consisting of two antennas, facilitating more accurate determination of the azimuth angle of the second electronic device carrying the UWB positioning tag relative to the first electronic device.

The accuracy of seeking and confirming the electronic equipment position indoors can be strengthened through UWB range finding direction finding location, after determining the distance and the position of second electronic equipment for first electronic equipment, show through the screen of first electronic equipment, can improve efficiency and the degree of accuracy that the user looked for equipment.
Fig. 5 is a flowchart illustrating yet another display control method according to an exemplary embodiment.
Referring to fig. 5, in some embodiments, the type of the control command is a predetermined gesture type, and the controlling the first electronic device to start a screen display function in response to receiving the control command further includes the following steps:
in step S501, when the first electronic device is in an un-awake state, controlling a UWB radar ranging module of the first electronic device to transmit a pulse radar signal;
in step S502, in response to receiving a radar echo signal within a second predetermined range of the first electronic device, processing the radar echo signal to obtain a gesture echo signal;
in step S503, in response to receiving a radar echo signal within a second predetermined range of the first electronic device, processing the radar echo signal to obtain a gesture echo signal;
in step S504, in a case that the gesture represented by the gesture echo signal matches the predetermined gesture type, controlling the first electronic device to start a screen display function.
Gesture recognition, an important human-computer interaction technology, is usually implemented by means of a sensor or a camera. However, the gesture recognition implemented by using a sensor or a camera often requires a user to contact the electrode and the sensor, or to acquire an image through modules such as a camera, which brings inconvenience and privacy-related problems. According to the embodiment of the disclosure, gesture recognition can be realized more conveniently and safely through the UWB radar ranging module.
When first electronic equipment is in an un-awakened state, such as a dormant state or a power-off state, controlling the UWB radar ranging module of the first electronic equipment to be in a working state and transmitting a pulse radar signal;
in some possible embodiments, the UWB radar ranging module is in heartbeat connection in this scenario, and the transmitted pulsed radar signal may be a narrow pulse form carrierless signal, which may be identified by a gaussian signal, for example.
Responding to the received radar echo signal within the second preset range of the first electronic device, and processing the radar echo signal to obtain a gesture echo signal;
it should be noted that, when the first electronic device is in a sleep state or a power-off state, the pulse radar signal sent by the UWB radar ranging module is limited to an average power, and an acting distance of the pulse radar signal is relatively accurate within a second predetermined range. The second predetermined range may be set to a range within a second predetermined distance from the first electronic device, and the specific value of the distance may be derived from the test.
For example, it may be set within a range of positions between 70-150 centimeters from the first electronic device. Because the original radar echo signal includes distance information of a plurality of scattering center points of a human body, the radar echo signal needs to be processed to obtain a gesture echo signal, and action features associated with a preset gesture are extracted. For example, feature information of the distance information changing with time may be extracted.
Then, the obtained gesture echo signal can be input into a convolutional neural network model trained according to a preset gesture, the depth feature of the gesture echo signal is further extracted, and the gesture with the maximum probability represented by the gesture echo signal is determined.
The specific predetermined gesture corresponding to the predetermined gesture type may be set as required, which is not limited in this disclosure. As shown in fig. 6, taking the first electronic device as an example of the smart phone, the predetermined gesture may be set to draw an 1/4 elliptical trajectory from the front of the chest to the upper right of the arm. When the user cannot find the remote control device which is standard for controlling the intelligent television, the control instruction can be sent by inputting a preset gesture in the position range between 70 and 150 centimeters of the television device so as to control the intelligent television to start the screen function. And the intelligent television starts a screen display function and enters an awakening state under the condition that the gesture represented by the gesture echo signal is judged to be matched with the preset gesture type.
Therefore, the UWB radar ranging module of the first electronic equipment can keep a low-power-consumption detection state under the conditions of the sleep state or the power-off state, and whether a gesture echo signal matched with a preset gesture exists in the second preset range or not is identified by sending a pulse radar signal, so that the first electronic equipment is controlled to start a screen display function and enter a wakeup state or a power-on state. Therefore, the user can be simply controlled to wake up or start up the first electronic device in a gesture recognition mode, the position information of the device needing to be positioned in the display chamber of the first electronic device is further controlled under the condition that the preset condition is met, the user can conveniently find the device which the user wants to find, the user experience is improved, and the efficiency of finding the second electronic device is enhanced.
In some embodiments, after the first electronic device is woken up, in order to more accurately recognize the gesture, the device to be found may be determined by recognizing the gesture already defined by using a camera included in the device, and the first electronic device may be further controlled to display the location information of the device to be found. For example, when the first electronic device is a television device, the UWB radar ranging module may recognize a gesture wake-up instruction, and after the television device is woken up by a gesture, the television AI camera may recognize a defined gesture to determine a device to be searched. Or a guiding interface can be displayed in a preset area of the television equipment, the gesture guiding of all equipment carrying the UWB positioning tags is displayed, and the corresponding relation between the specific gesture and the specific equipment carrying the UWB positioning tags is marked, so that the user can conveniently carry out indoor object finding and positioning.
In certain embodiments, the method further comprises the steps of:
receiving an input instruction under the condition that the first electronic equipment starts a screen display function, wherein the input instruction is used for indicating equipment information of equipment to be searched;
and displaying the position information of the equipment to be searched on a screen according to the input instruction.
In this embodiment, after the first electronic device is in the wake-up state, it is not necessary to determine whether the wake-up instruction satisfies the predetermined condition, or the first electronic device may also receive an input instruction when the wake-up instruction does not satisfy the predetermined condition, where the input instruction is used to indicate device information of the device to be searched, and control the first electronic device to display location information of the device to be searched according to the input instruction.
In practical application, after the first electronic device is in the wake-up state, the user can express that the user needs to search for the device by inputting an instruction. For example, the device information of the device to be found is indicated by means of voice input or gesture input, so that the first electronic device can be controlled to display the position information of the device to be found according to the input instruction. For example, when a user needs to search for a device, the user can wake up a television device with the largest display screen in home through gestures, and indicate the device information of the device to be searched through a voice input or gesture input mode, and the television device sends a pulse positioning signal through a UWB radar ranging module of the television device, so that the position of the device carrying a UWB positioning tag in the room can be determined, and the position information is displayed in a preset area of the screen of the television device. So, can make the more efficient indoor electronic equipment of seeking of user, promote user's use in the intelligent house scene and experience with the linkage between the equipment under this scene.
