An application program can access resources in a system and acquire services of the system in execution through an API interface

As shown in fig. 4, the application framework layer in the embodiment of the present application includes a manager (Managers), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an activity manager (ACTIVITY MANAGER) is used to interact with all activities running in the system; a Location Manager (Location Manager) is used to provide system services or applications with access to system Location services; a package manager (PACKAGE MANAGER) for detecting various information about an application package currently installed on the device; a notification manager (Notification Manager) for controlling the display and clearing of notification messages; a Window Manager (Window Manager) is used to manage bracketing icons, windows, toolbars, wallpaper, and desktop components on the user interface.

In some embodiments, the activity manager is to: the lifecycle of each application program is managed, as well as the usual navigation rollback functions, such as controlling the exit of the application program (including switching the currently displayed user interface in the display window to the system desktop), opening, backing (including switching the currently displayed user interface in the display window to the previous user interface of the currently displayed user interface), etc.

In some embodiments, the window manager is configured to manage all window procedures, such as obtaining a display screen size, determining whether there is a status bar, locking the screen, intercepting the screen, controlling display window changes (e.g., scaling the display window down, dithering, distorting, etc.), and so on.

In some embodiments, the system runtime layer provides support for the upper layer, the framework layer, and when the framework layer is in use, the android operating system runs the C/C++ libraries contained in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software. As shown in fig. 4, the kernel layer contains at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (e.g., fingerprint sensor, temperature sensor, touch sensor, pressure sensor, etc.), and the like.

In some embodiments, the kernel layer further includes a power driver module for power management.

In some embodiments, the software programs and/or modules corresponding to the software architecture in fig. 4 are stored in the first memory or the second memory shown in fig. 2 or fig. 3.

In some embodiments, taking a magic mirror application (photographing application) as an example, when the remote control receiving device receives an input operation of the remote control, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into the original input event (including the value of the input operation, the timestamp of the input operation, etc.). The original input event is stored at the kernel layer. The application program framework layer acquires an original input event from the kernel layer, identifies a control corresponding to the input event according to the current position of the focus and takes the input operation as a confirmation operation, wherein the control corresponding to the confirmation operation is a control of a magic mirror application icon, the magic mirror application calls an interface of the application framework layer, the magic mirror application is started, and further, a camera driver is started by calling the kernel layer, so that a still image or video is captured through a camera.

In some embodiments, for a display device with a touch function, taking a split screen operation as an example, the display device receives an input operation (such as a split screen operation) acted on a display screen by a user, and the kernel layer may generate a corresponding input event according to the input operation and report the event to the application framework layer. The window mode (e.g., multi-window mode) and window position and size corresponding to the input operation are set by the activity manager of the application framework layer. And window management of the application framework layer draws a window according to the setting of the activity manager, then the drawn window data is sent to a display driver of the kernel layer, and the display driver displays application interfaces corresponding to the window data in different display areas of the display screen.

In some embodiments, as shown in fig. 5, the application layer contains at least one icon control that the application can display in the display, such as: a live television application icon control, a video on demand application icon control, a media center application icon control, an application center icon control, a game application icon control, and the like.

In some embodiments, the live television application may provide live television via different signal sources. For example, a live television application may provide television signals using inputs from cable television, radio broadcast, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

In some embodiments, the video on demand application may provide video from different storage sources. Unlike live television applications, video-on-demand provides video displays from some storage sources. For example, video-on-demand may come from the server side of cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various multimedia content playing applications. For example, a media center may be a different service than live television or video on demand, and a user may access various images or audio through a media center application.

In some embodiments, an application center may be provided to store various applications. The application may be a game, an application, or some other application associated with a computer system or other device but which may be run in a smart television. The application center may obtain these applications from different sources, store them in local storage, and then be run on the display device 200.

Based on the above-described display apparatus 200, the user can access the various interface apparatuses 500 through the external device interface 240 of the display apparatus 200. The interface device 500 may be a device having a specific function, and the interface device 500 may be divided into an input means and an output means according to the specific function it has. For example, a camera, a microphone, a handle, or other devices capable of capturing video, audio, and motion signals are input devices; equipment such as a sound equipment and an external display which can output audio and video signals is an output device.

Wherein the input means may generate an electrical signal readable and/or processable by the display device 200 from the acquired signal. And transmits the collected electrical signals to the display apparatus 200 through the external device interface 240 so that the display apparatus 200 can implement different functions using the signals of the interface apparatus 500. The output device can convert the electrical signals in the display device 200 into other signals for outputting, so that the output device can be utilized to enrich the output modes of the audio and video signals.

The handle 501, as an input device, may be connected to the display apparatus 200 through the external device interface 240 to transmit pose information to the display apparatus 200. The handle 501 is integrated with an element based on pose tracking technology, so that position data and pose data of the handle 501 can be fed back in real time in the use process.

The handle 501 may incorporate different sensor elements depending on the position and posture of the handle 501. For example, in order to detect the current position of the handgrip 501, the handgrip 501 may incorporate a transmitting element and a receiving element based on a tracking system such as laser, ultrasonic, or the like. In order to detect the current posture of the handle 501, a gravity sensor, a gyroscope and other elements are also built in the handle 501. After the handle 501 is connected to the external device interface 240, the handle 501 may transmit its own position data and posture data to the display apparatus 200 in real time, so that the display apparatus 200 can acquire current posture information of the handle 501.

It should be noted that, the portion of the handle 501 is limited by the positioning principle, and the positioning base station 502 needs to be matched to send the position data to the display device 200. For example, using a laser or ultrasonic outlide-in pose tracking handle, the laser or ultrasonic positioning principles may be used to obtain the direction and distance between the handle 501 and the positioning base station 502, and determine the position of the handle 501 in three-dimensional coordinates from this distance data.

Therefore, as shown in fig. 6, in practical application, the display apparatus 200 may be connected to the positioning base station 502 through the external device interface 240, and then the positioning base station 502 is connected to the handle 501, so as to implement the connection of the handle 501 to the external device interface 240. It is apparent that both the positioning base 502 and the display device 200 can support multiple handles 501 to obtain relative positions at the same time.

The handle 501 may further be provided with a plurality of keys, so that a user may define key functions on the handle 501 in combination with specific usage scenarios to complete corresponding interactive functions. For example, during a conference discussion, the display device 200 may be used to display a file, and the conference participant may use the keys on the handle 501 to perform operations in the displayed screen, such as scribing, circling, and drawing a box, so as to mark the display content at a specific position, so as to assist in expressing his or her own view.

Accordingly, the display apparatus 200 can receive the pose information of the handle 501 through the external device interface 240 and can also receive the operation information performed on the handle 501 by the user. The pose information and the operation information may be transmitted to the controller 250 through the external device interface 240, thereby enabling the controller 250 to control the display 275 to display a pattern for characterizing the manipulation process in real time.

The manipulation pattern may include two kinds, one being a tracking mark for tracking the position and posture of the handle 501 and the other being an action pattern drawn according to the interactive action input by the user. The tracking marks may have a specific shape, for example, pointers, circles, diamond blocks, etc. In order to track the position and posture of the handle 501, the position of the tracking mark needs to be changed along with the change of the position of the handle 501, for example, when the user operates the handle 501 to move leftwards, the tracking mark also moves leftwards to the display 275 in real time. In some embodiments of the present application, when the display device 200 is coupled with a plurality of handles 501, the plurality of tracking marks may be distinguished by different colors and/or different shapes.

The action pattern may be drawn in real time from the interactive actions entered by the user. The drawn action patterns are also different under different interaction actions. For example, when performing a scribing operation, the user may start the scribing operation by pressing a key defined as a scribing function on the handle 501 while moving the position of the handle 501, and the display apparatus 200 displays a path of movement through a curve in the displayed contents, forming an action pattern.

For another example, when performing the circle operation, the user may press the corresponding key after selecting the circle operation function, and then display a circle pattern at a position corresponding to the tracking mark when the key is pressed by the display device 200, and adjust the size and shape of the circle in real time along with the movement of the handle until the user releases the corresponding key to form a final action pattern.

The marking locations required to be performed on the displayed content are also different for different displayed content, and for different conference participants, so that when the handle 501 is operated, the user can adjust the position and/or posture of the handle 501, so as to mark the displayed content at different positions.

In order to achieve the above functions, as shown in fig. 7, some embodiments of the present application provide a handle manipulation pattern display method, which may be configured in a controller 250 of a display device 200, the method including the steps of:

s1: and acquiring pose information of the handle through the external device interface.

After the handle 501 is connected to the external device interface 240, the controller 250 may acquire pose information of the handle 501 at a set frequency for determining the current position and pose of the handle 501. The pose information includes current position data, pose data, and a handle identification ID of the handle 501.

To distinguish between different handles 501, each handle 501 may be provided with a handle identification ID. The handle identification ID may be custom set by the user through the display apparatus 200 after accessing the external device interface 240. For example, the display device 200 adds a handle identification ID, such as a serial number, a port number, etc., to the handle 501 according to a set rule after completing the software configuration of the handle 501. The handle identification ID may also be automatically set by the display device 200 by reading the model code of the handle 501 device, for example, the handle identification ID may be any code obtained by reading the handle 501 that can indicate its uniqueness, including Mac address, product main board number, and the like.

In practice, each handle 501, when connected to the display device 200, requires the display device 200 to adapt to the handle 501, for example, to install a driver or the like. After the adaptation is completed, the display apparatus 200 may store the handle identification ID corresponding to the accessed handle 501 so that the adaptation can be directly completed the next time the handle 501 is accessed to the display apparatus 200.

After the handle 501 is connected to the external device interface 240, the handle 501 may transmit the position data and the posture data to the display apparatus 200 through the external device interface 240 in real time. In order to distinguish between different handles 501 for subsequent analysis, a handle identification ID may also be included in the pose information sent by the handles 501 to the display device 200. Specifically, when pose information is transferred, the position data and the pose data may be encapsulated in a data packet, and a tag with a handle identification ID is added to the data packet, so that the controller 250 can obtain the pose information.

S2: and calculating the mapping point position of the handle on the display according to the current position data and the gesture data.

After the pose information of the handle 501 is obtained, the controller 250 may analyze the pose information to obtain position data and pose data in the pose information, and then map the position and pose of the handle 501 to a display area of the display 275 according to the arrangement condition of the handle 501 in the actual operation space. I.e. the mapped point position of the handle 501 on the display 275 is calculated from the position data and the pose data where the handle 501 is located.

In practice, each position and each gesture of the handle 501 may correspond to a mapping point on the display 275. The specific mapping mode can set the mapping rule according to the pose detection principle of the handle 501. For example, the handle 501 may be equivalent to an origin whose orthographic position on the display 275 may be used as a mapped point position of the handle 501 on the display 275. Thus, when the user moves the position of the handle 501, the position of the mapping point will also change, thereby facilitating the subsequent display of the manipulation pattern.

For a portion of the handle 501, the map point locations may be determined on the display 275 according to the spatial geometric projection relationship from the position data and the pose data. For example, for a handle 501 of cylindrical configuration, the mapping point may be the intersection of the extension of the central axis of the handle 501 with the plane of the display 275. Such a mapping manner may enable the gesture of the handle 501 to directly correspond to the point pointed to the display device 200 when the handle 501 is pointed to the display device 200 according to the usage habit of the user when the handle 501 is located at a certain distance from the display device 200, and accurately map on the display device 200. The mapping point positions can be changed when the user moves the handle 501 and rotates the handle 501, so that the user can conveniently execute operations.

S3: and controlling the display to display the control pattern in real time according to the position of the mapping point.

After determining the map point location, the controller 250 may also display the operation pattern in real time according to the map point location. To distinguish the operation patterns of the different handles 501, the color and/or pattern shape of the control displayed manipulation pattern may be set according to the handle identification ID.

For example, the handle identification ID may be a serial number generated in the order in which the handle 501 is matched with the display device 200, and when the manipulation pattern is displayed, the color of the handle-corresponding manipulation pattern with the serial number 01 is red, the color of the handle-corresponding manipulation pattern with the serial number 02 is purple, the color of the handle-corresponding manipulation pattern with the serial number 03 is green, the color of the handle-corresponding manipulation pattern with the serial number 04 is blue, and the color of the handle-corresponding manipulation pattern with the serial number 05 is black. Distinct colors are distinguished by different and contrasting colors to display the control patterns corresponding to the different handles 501.

Similarly, the manipulation patterns corresponding to the plurality of handles 501 may be distinguished by displaying different pattern shapes. For example, the handle with the number 01 corresponds to the shape of the control pattern to be a circle; the handle with the serial number of 02 corresponds to the shape of the control pattern to be rectangular; the handle with the serial number 03 corresponds to the control pattern in a triangle shape; the handle with the serial number 04 corresponds to the shape of the control pattern to be diamond; the handle with the number of 05 is trapezoid in shape corresponding to the control pattern, so that the control patterns corresponding to different handles 501 can be displayed through different shapes.

Obviously, since the operation pattern may include the tracking mark and the action pattern, both the tracking mark and the action pattern may be simultaneously set at the time of setting the color and/or the pattern shape according to the handle identification ID, and the tracking mark may be adapted to the action pattern. For example, the handle with the number 01 corresponds to the control pattern, the color of the control pattern is red, the trace mark is a red circular pattern, and the corresponding generated action pattern can also be adapted to the red circular pattern, for example, when the scribing operation is performed, the formed scribing line is a line with the end part in a circular arc shape, the color of the line is red, and the width of the line is equal to the diameter of the circle in the trace mark.

It should be noted that, in practical applications, the control pattern displayed corresponding to the same handle 501 may have various forms. For example, the handle corresponding manipulation pattern with the number 01 can be red round or yellow pentagram, and can be switched by user operation so as to adapt to different background patterns or different expression intentions.

As can be seen from the above technical solutions, the method for displaying a handle manipulation pattern provided in the above embodiments may be configured in the controller 250 of the display device 200, so as to monitor the position and the posture of the handle 501 in real time, and map the position and the posture in the display area of the display 275, thereby controlling the display 275 to display the manipulation pattern in real time according to the mapping point. The color and/or pattern shape of the displayed manipulation patterns can be set according to the different handles 501, so as to realize the distinction of the manipulation patterns of the different handles 501. The method can fully utilize the display device 200 to support the interactive function of the multi-handle 501, is convenient for operators of different handles 501 to perform interactive operation with the display device 200, and provides more diversified and personalized interactive modes.

In the above embodiment, different handles 501 may be provided with different manipulation patterns, and the process of setting the manipulation patterns may be completed after the handles 501 are connected to the external device interface 240. Since the handle 501 is to be reconnected each time the display device 200 is turned on, in some embodiments of the present application, the method further comprises:

S401: acquiring a starting instruction input by a user;

S402: detecting a handle identification ID connected to the external device interface in response to the power-on instruction;

S403: setting a color and/or pattern shape of a manipulation pattern for each handle connected to the external device interface;

s404: creating an information label;

S405: and storing the information tag.

During each power-on start-up, a user may input a power-on command through the control apparatus 100 or through a power-on key on the display device 200. After receiving the power-on command, the controller 250 may detect the handle identification ID accessed to the external device interface 240 in response to the power-on command.

And setting the color and/or shape of the control pattern for each handle 501 according to the detected handle identification ID, and creating an information tag (informationTab) for recording the setting result, i.e. the handle identification ID and the color and/or pattern shape of the control pattern corresponding to the handle identification ID are recorded in the information tag. And finally, storing the created information label for subsequent calling.

For example, after powering on the display device 200, when the pose tracking handle 501 is detected by the USB external wireless communication module, informationTab is created to record the information of the handle 501. In informationTab, each record contains information such as serial number, handle identification ID, manipulation pattern color, manipulation pattern shape, etc. for application query.

The information tag of the display device 200 may be powered down and not saved, and the handle 501 is reconnected at each power-on to create the information tag, thereby reducing the data storage amount and timely updating the content recorded in the information tag. Obviously, in the startup use of the display apparatus 200, if the handle 501 is powered down and powered up again, after obtaining the information that the handle 501 is connected to the external device interface 240, the display apparatus 200 may search the information label stored in advance for the recorded serial number and the information such as the color and shape of the control pattern by adopting a mode of searching for the handle identification ID, so as to facilitate quick determination of the color and shape of the control pattern corresponding to the handle identification ID.

In the above embodiment, since the display apparatus 200 can theoretically support an infinite number of handles 501 for access, the display apparatus 200 needs to set the manipulation patterns thereof to achieve mutual distinction for each handle 501 for access. Thus, in some embodiments, the step of setting the color and/or pattern shape of the manipulation pattern for each handle connected to the external device interface further comprises:

s4031: generating primary color data;

s4032: combining the primary color data generates a color of the manipulation pattern.

In order to set a different manipulation pattern for each of the handles 501, when setting a color of the manipulation pattern for each of the handles 501 connected to the external device interface 240, primary color data may be generated first, and then the colors of the manipulation patterns generated from the primary color data may be combined to generate a color of the handle 501 corresponding to the manipulation pattern. Wherein, the primary color data includes three random numbers between 0 and 255, which are respectively used to represent the RGB three primary color values of the manipulation pattern, that is, the colors corresponding to each handle 501 are respectively used as the corresponding RGB three primary colors of the manipulation pattern in a manner of obtaining three random numbers between 0 and 255, and the colors of the manipulation pattern can be determined after the values of the three primary colors are determined.

Obviously, when the color of the manipulation pattern is set, there should be a difference in the color corresponding to the setting of the different handles 501, and thus the obtained three times random number cannot be the same as the corresponding color of the other handles that have been set. That is, after the three random numbers are obtained, the three random numbers can be compared with the control pattern colors recorded in the stored information labels once, and if the generated control pattern colors are the same as any recorded control pattern color of the handle 501, the three random numbers are regenerated until the control pattern of the handle 501 is set to other colors.

It should be noted that, in order to avoid that the set control pattern color is the same as the other set control pattern colors, the corresponding set color primary color values under one or more primary colors may be deleted in the range 0-255 where the three random numbers are obtained, so as to directly obtain primary color data different from the set colors, and generate different control pattern colors.

Similarly, the setting of the shape of the manipulation pattern may be performed by selecting a mode from a preset set. For example, a set of shapes of the control pattern may be stored in the display device 200, each shape may correspond to a serial number, which may be the same as the serial number of the handle 501, so that after determining the serial number of the handle 501, the corresponding control pattern shape is determined directly according to the serial number.

As can be seen from the above technical solutions, the above embodiments can implement unified management of the handles 501 that will be connected to the external device interface 240 by storing information tags in the display apparatus 200, and can be queried by application programs to implement interaction between the plurality of handles 501 and the display apparatus 200.

In order to connect a greater number of handles 501 and adapt the positioning of portions of the handles 501, in some embodiments of the present application, a positioning base station 502 is connected to the external device interface 240, such that a plurality of handles 501 access the external device interface 240 through the positioning base station 502. The positioning base 502 is a device that cooperates with the handle 501 to position the handle 501. Thus, the positioning base 502 may have the same signal detection principle as the handle 501, such as a positioning principle based on laser or ultrasound.

For example, for a portion of the handle 501, the positioning base station 502 may perform a scan by transmitting a particular form of laser signal in a different direction. The handle 501 in the scanning range may receive the laser signal and feed back the signal. The positioning base station 502 can detect the feedback signal and determine the position of the handle 501 according to the position of the feedback signal and the transmission time of the feedback signal, so as to position the handle 501. After the positioning is completed, the positioning base station 502 may generate position data corresponding to the handle 501 and transmit the position data to the display apparatus 200 through the external device interface 240.

It should be noted that, the positioning base station 502 may also perform data communication with the handle 501 in real time, so as to receive gesture data detected by elements such as a gravitational acceleration sensor and a gyroscope in the handle 501. And, after receiving the gesture data, the positioning base station 502 may combine the gesture data with the position data detected in the same period, thereby uniformly transmitting to the display device 200.

The positioning base 502 may be positioned at a location that facilitates scanning of the handle 501. The positioning base 502 is fixed in position relative to the display 275 and the controller 250 can obtain the relative position information. The positioning base station 502 may be fixed around the display 275, for example, at a top center position of the display 275. At this point, the center point distance and the offset angle from the center point of the positioning base station 502 to the center point of the display 275 are fixed, which can facilitate accurate determination of the spatial geometry. In some embodiments, the step of calculating the mapped point position of the handle on the display further comprises:

s201: measuring three-dimensional position coordinates of the handle relative to the positioning base station, and a horizontal attitude angle and a vertical attitude angle of the handle through the positioning base station;

S202: acquiring a width value and a height value of the display, and acquiring a distance value between the positioning base station and the display;

s203: calculating the horizontal coordinates of the mapping points according to the three-dimensional position coordinates, the width values and the horizontal attitude angles;

s204: and calculating the vertical coordinates of the mapping points according to the three-dimensional position coordinates, the height values and the vertical attitude angles.

In this embodiment, the position data may include the relative position of the handle 501 with respect to the positioning base station, which may be represented by three-dimensional position coordinates (x, y, z). The pose data may be obtained from IMU information of the handle 501 and positioning base station 502 ultrasound/laser information received by the handle 501. The posture data may include inclination angles of the handle 501 with respect to the horizontal direction and the numerical direction, and the expression β is made by the horizontal posture angle α and the vertical posture angle, respectively.

Meanwhile, as shown in fig. 8, the controller 250 may also acquire a width value and a height value of the display 275, and acquire a distance value D between the positioning base station 502 and the display 275. Among them, the width value W and the height value H of the display 275, i.e., screen size, may be determined according to the display devices 200 of different specifications. For example, a 65 inch smart television has a width of 1480mm and a height of 897mm. The distance value D is determined according to the placement position of the positioning base station 502.

After acquiring the data, the controller 250 may map the position data and the posture data of the handle 501 onto the display 275 according to the spatial geometry of the handle 501 and the display device 200. To facilitate expressing the mapping point position, a rectangular coordinate system may be constructed on the plane of the display 275 with the bottom left corner of the display 275 as the origin, and the mapping point position is expressed in the rectangular coordinate system, that is, the mapping point position coordinates are P (lcd_w, lcd_h).

Specifically, as shown in fig. 9, the horizontal coordinates of the map points may be calculated from the three-dimensional position coordinates, the width values, and the horizontal attitude angles. That is, the horizontal coordinates of the mapping points are:

lcd_w＝(x*tanα+W/2+y)；

Wherein, lcd_w is the horizontal coordinate of the mapping point; x is a horizontal x-axis coordinate in the three-dimensional position coordinates; y is a horizontal y-axis coordinate in the three-dimensional position coordinates; alpha is a horizontal attitude angle; w is the width value of the display;

as shown in fig. 10, the vertical coordinates of the mapping points may be calculated from the three-dimensional position coordinates, the height values, and the vertical attitude angles. That is, the vertical coordinates of the mapping points:

Lcd_h＝H-(-z-D-tanβ*x)；

Wherein Lcd_h is the vertical coordinate of the mapping point; h is the height value of the display; x is a horizontal x-axis coordinate in the three-dimensional position coordinates; z is a vertical z-axis coordinate in the three-dimensional position coordinates; d is a distance value between the positioning base station and the display; beta is the vertical attitude angle.

It can be seen that in this embodiment, the position coordinates of the intersection point of the central axis extension line of the handle 501 and the plane of the display 275 can be determined by a spatial geometrical relationship, so as to determine the position of the mapping point. It should be noted that, along with the operation of the user, the intersection point between the axis extension line of the handle 501 and the plane of the display 275 may exceed the display area, and at this time, the manipulation pattern may be fixedly displayed at the edge position when the display area is exceeded. That is, after calculation by the above formula, if lcd_h is negative or greater than H, the range of the display 275 is exceeded, and the manipulation pattern may be displayed at the edge position adjacent to the exceeding direction; if lcd_w is negative or greater than W, the steering pattern may be displayed at an edge position adjacent in the out-of-direction beyond the range of the display 275.

After the mapping point position of the handle 501 on the display 275 is obtained through calculation, on one hand, the mapping point position can be tracked in real time through tracking marks, so that a user can conveniently determine the position of an interaction control point; on the other hand, the action pattern may be displayed when the user performs a partial interactive operation.

For example, when the user performs a scribing operation, scribing may be started by pressing a key of a corresponding function on the handle 501. And moves the position of the handle 501 or changes the posture of the handle 501 to continuously form a line. And (5) releasing the key until the specific position is reached, and ending scribing.

Because, in order to display the action pattern, in some embodiments of the present application, the step of controlling the display to display the manipulation pattern in real time according to the mapped point position further includes:

s311: acquiring operation information input by a user through a handle;

s312: creating an input label;

S313: and storing the input label.

In practical applications, the user may input various operation actions through the handle 501, and the handle 501 may convert the operation actions into operation information and send the operation information to the display device 200 together with pose information. Accordingly, the controller 250 may acquire operation information input by the user through the handle 501, and then create an input tag (InputInformTab) according to the operation information and store it. The input label is recorded with a handle identification ID, a key identification serial number, key event data and a mapping point position corresponding to pose information according to the operation information.

For example, the display device 200 receives the real-time information of the pose of the handle 501 and the operation information through the USB interface and saves them in InputInformTab. InputInformTab records a handle identification ID, a key identification number, a key press or lift event, calculated position information of the handle pointing direction, etc.

Wherein InputInformTab may be a circular queue of size 65536. Taking the Linux/android system as an example, when the display device 200 receives the operation information of the handle 501, it may call the function "send_event" and set the type parameter as "ev_msc", the code parameter as "msc_raw" and the value parameter as the last recorded serial number in Inp utInformTab in the key parameters of the function. The function "send_event" may send an event to the application reminding the application to query for operational information.

In addition, in practical applications, the operation information and the pose information of the multiple handles 501 need to be provided with the identification ID information of the handles 501, so as to distinguish the operations of the multiple handles 501 and prevent confusion of the operation events of the multiple handles 501.

In some embodiments, in order to present the tracking mark and the action pattern in the display screen, in the step of displaying the operation pattern, two layers may be created for each handle 501 to be used for displaying the tracking mark and the action pattern, respectively, so the step of controlling the display to display the manipulation pattern in real time according to the mapping point position further includes:

S321: invoking the input label;

S322: displaying a tracking mark for tracking the position of the mapping point on a first image layer in real time according to the handle identification ID and the position of the mapping point in the input label;

s323: drawing an action pattern on a second layer according to the handle identification ID, the key identification serial number, the key event data and the mapping point position in the input label;

S324: and controlling the display to display the first image layer and the second image layer.

In the display device 200, the stored input labels may be invoked by an application program to generate tracking marks and action patterns, respectively. The position of the tracking mark can be adjusted in real time according to the handle identification ID and the mapping point position in the input label, so that the tracking mark always moves along with the mapping point position. The action pattern can be generated by comprehensively determining the handle identification ID, the key identification serial number, the key event data and the mapping point positions in the input label.

For example, the application software queries InputInformTab and/or informationTab that the stored information includes a handle identification ID, a manipulation pattern color or shape, a key identification number, key event data, and a map point location, and draws an action pattern. The pressing position and the lifting position are extracted from the case event data, and the scribing trace is determined by the change of the mapping point position between the two positions, thereby forming a line pattern, as shown in fig. 11.

During the display process, the application software of the display device 200 may set two layers (surfaces) in surfaceflinger for each handle 501 when using the information transferred by the handles 501. One of the positions pointed by the corresponding pose tracking handles is displayed on the first image layer; and the other operation pattern corresponds to the operation pattern such as the circling, the marking symbol and the like, namely the display of the action pattern is completed on the second layer. Finally, real-time layer composition is performed as needed in Surfaceflinger services and displayed on display 275.

It can be seen that, in the above embodiment, two layers may be set for each handle 501 to display the tracking mark and the action pattern, so that tracking of the action may be achieved without affecting specific interaction, and mutually independent layers are correspondingly set for the visualized operation of each handle, so as to avoid the influence between the interaction of multiple handles 501.

In some embodiments, to further eliminate interaction between interactions of the multi-handle 501, the step of controlling the display to display the manipulation pattern in real time according to the mapped point positions further includes:

s331: acquiring a key instruction for preferential display from the key event data;

s332: responding to the key instruction, and controlling the display to display the first layer and the second layer corresponding to the current handle;

s333: hiding the first image layer and the second image layer corresponding to other handles.

The user may also input a key instruction for preferential display through a key having a preferential display function on the handle 501, and after receiving the key instruction, the controller 250 may control the display 275 to adjust the displayed layer, that is, only the layer where the tracking mark and the action pattern corresponding to the current handle are located is displayed, and the layer where the tracking mark and the action pattern corresponding to the other handles are located is hidden. It is realized that when the content of the mark is too much, the control Surfacefl inger does not display the layers of other handles by using the keys on the handle 501.

Obviously, different handles can be provided with different priority display request rights, namely, for a handle with higher rights, all layers corresponding to the handle with lower priority display request rights can be hidden through a key instruction of priority display. The handle with lower authority cannot hide the layers corresponding to other handles with higher authority than the handle, and only the layers corresponding to other handles with lower authority than the handle can be hidden.

In addition, the keys on the handle 501 may be configured to have different interactive functions through software configuration, for example, a cancel instruction, a redo instruction, etc. may be input through the handle keys, and the controller 250 of the display device 200 may perform the corresponding functions through executing the control program after receiving the corresponding instructions.

Based on the above-mentioned method for displaying a handle manipulation pattern, some embodiments of the present application further provide a display apparatus 200, including a display 275, an external device interface 240, and a controller 250.

Wherein the display 275 is configured to display a user interface and a manipulation pattern; the external device interface 240 is configured to access a handle 501; the controller 250 is configured to perform the following program steps:

S1: acquiring pose information of the handle through the external device interface, wherein the pose information comprises current position data, pose data and handle identification ID of the handle;

S2: calculating the mapping point position of the handle on the display according to the current position data and the gesture data;

s3: and controlling the display to display a control pattern in real time according to the position of the mapping point, wherein the color and/or pattern shape of the control pattern is set according to the handle identification ID.

The controller 250 may enable the user to perform various, personalized interactions through the handle 501 by performing the steps described above. The display device 200 may be used as a fixed location public screen for multiple people to use simultaneously.

For example, when a person participating in a conference uses the display device 200 to point out a certain part of the displayed content, the gesture tracking handle 501 may be used to complete a pointing action, and the controller 250 determines the position of a mapping point on the display 275 according to the gesture information corresponding to the pointing action, and then presses a key of the handle 501 to implement operations such as circling, marking symbols and the like at a selected position to add a mark to the content in question.

The display device 200 can make full use of the functions of the supported pose tracking handle 501, and at the time of conference discussion, enables participants of each conference to conveniently point out their attention points on the current display content to express their own views, and does not affect the expression of main views of main people.

As can be seen from the above description, the display apparatus 200 according to the first aspect of the present application includes a display 275, an external device interface 240 and a controller 250. The controller 250 may acquire pose information of the handle 501 through the external device interface 240, and calculate a mapping point position of the current state of the handle 501 on the display 275 according to position data and pose data in the pose information, so as to display a manipulation pattern in real time according to the mapping point position, and control the display 275 to display. The display device 200 may enable interaction via the handle 501 to provide a more versatile, personalized way of interaction.

The above-provided detailed description is merely a few examples under the general inventive concept and does not limit the scope of the present application. Any other embodiments which are extended according to the solution of the application without inventive effort fall within the scope of protection of the application for a person skilled in the art.
