The kernel layer processes the input operation into an original input event (including information such as a value of the input operation, a timestamp of the input operation, etc.). The raw input events are stored at the kernel layer. The application program framework layer obtains 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 uses the input operation as a confirmation operation, 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 to start the magic mirror application, and then the kernel layer is called to start a camera driver, so that a static image or a video is captured through the camera.

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 input from cable television, radio broadcasts, 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, a video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various applications for multimedia content playback. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

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

Based on the above-described display apparatus 200, a user can access 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 device and an output device according to the specific function. For example, devices capable of acquiring video, audio, and motion signals, such as a camera, a microphone, and a handle, are input devices; the equipment capable of outputting audio and video signals, such as a sound box, an external display and the like, is an output device.

The input device may generate an electrical signal that can be read and/or processed by the display apparatus 200 according to 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 various functions using the signals of the interface apparatus 500. The output device can convert the electrical signal in the display device 200 into other signals for outputting, so as to enrich the output mode of outputting audio and video signals by using the output device.

The handle 501 serves as an input means, and can access 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 a pose tracking technology-based element, so that position data and posture data of the handle 501 can be fed back in real time in the using process.

Different sensor elements may be built into the handle 501 depending on the manner of detection of the position and posture used by the handle 501. For example, in order to detect the current position of the handle 501, the handle 501 may have a transmitting element and a receiving element built therein based on a tracking method such as laser or ultrasonic. The handle 501 also incorporates components such as a gravity sensor and a gyroscope to detect the current posture of the handle 501. After the handle 501 is connected to the external device interface 240, the handle 501 may transmit the position data and the posture data of the handle 501 to the display apparatus 200 in real time, so that the display apparatus 200 can acquire the current pose information of the handle 501.

It should be noted that part of the handle 501 is limited to the positioning principle, and the positioning base station 502 needs to be matched to transmit the position data to the display device 200. For example, the outside-in pose of laser or ultrasonic is used to track the handle, which can use the laser or ultrasonic positioning principle 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 the three-dimensional coordinates according to the distance data.

Therefore, as shown in fig. 6, in practical applications, the display apparatus 200 may be connected to the positioning base station 502 through the external device interface 240, and then connected to the handle 501 through the positioning base station 502, so as to enable the handle 501 to access the external device interface 240. It is apparent that both the positioning base station 502 and the display device 200 can support a plurality of the handles 501 while obtaining relative positions.

The handle 501 may further have a plurality of keys, and a user may define the key functions on the handle 501 in combination with a specific usage scenario to complete corresponding interactive functions. For example, in a conference discussion, a file may be displayed using the display device 200, and a conference participant may perform an operation in a displayed frame using a key on the handle 501, such as drawing a line, a circle, a square, or the like, to mark a display content at a specific position to assist in expressing his/her own viewpoint.

Accordingly, the display apparatus 200 can receive the posture information of the handle 501 and also receive the operation information performed on the handle 501 by the user through the external device interface 240. Pose information and operational information may be sent to the controller 250 via the external device interface 240, thereby enabling the controller 250 to control the display 275 to display a pattern characterizing the steering process in real time.

The manipulation pattern may include two types, one is a tracking mark for tracking the position and posture of the handle 501, and the other is a motion pattern drawn according to the interactive motion input by the user. The tracking mark may have a specific shape, such as a pointer, a circle, a diamond, and the like. 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 to the left, the tracking mark also moves to the left side of the display 275 in real time. In some embodiments of the present application, when multiple handles 501 are connected to the display device 200, multiple tracking marks may be distinguished by different colors and/or different shapes.

The action pattern may be rendered in real time according to the interactive action input by the user. Under different interaction, the drawn action pattern is also different. For example, when a user starts a line drawing operation by pressing a key defined as a line drawing function on the handle 501 while moving the position of the handle 501, the display device 200 displays a moving path through a curve in the displayed content, and forms an action pattern.

For another example, when the circle drawing operation is performed, the user may press the corresponding key after selecting the circle drawing operation function, and then a circle pattern may be displayed at a position corresponding to the tracking mark when the display device 200 presses the key, and the size and shape of the circle may be adjusted in real time along with the movement of the handle until the user releases the corresponding key, and a final action pattern may be formed.

For different contents displayed and different conference participants, the marking positions of the displayed contents are different, so that when the handle 501 is operated, the user can adjust the position and/or posture of the handle 501, and the displayed contents are marked at different positions.

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

s1: and acquiring the 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 according to the set frequency, so as to determine the current position and pose of the handle 501. The pose information includes current position data, posture data, and a handle identification ID of the handle 501.

In order 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, after the software configuration is completed on the handle 501, the display device 200 adds a handle identification ID, such as a serial number, a port number, and the like, to the handle 501 according to a set rule. 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 a Mac address, a product motherboard number, and the like.

In practical applications, when each handle 501 is connected to the display device 200, the display device 200 needs to be adapted to the handle 501, for example, a driver is installed. After the adaptation is completed, the display device 200 may store the handle identification ID corresponding to the accessed handle 501, so that the adaptation can be directly completed next time the handle 501 is accessed to the display device 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 different handgrips 501 for subsequent analysis, a grip identification ID may also be included in the pose information sent by the handgrips 501 to the display device 200. Specifically, when the pose information is transmitted, the position data and the pose data may be encapsulated in the form of a data packet, and a tag with a handle identification ID may be added to the data packet, so that the controller 250 can acquire the pose information.

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

After obtaining the pose information of the handle 501, 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 the display area of the display 275 according to the arrangement 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 of the handle 501.

In practice, each position and each gesture of the handle 501 may correspond to a mapping point on the display 275. The specific mapping manner may be to set the mapping rules according to the pose detection principle of the handle 501. For example, the handle 501 may be equivalent to an origin, and the orthographic projection position of the origin on the display 275 may be used as the mapping 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.

While for a portion of handle 501, mapped point locations may be determined on display 275 in a spatial geometric projection relationship based on position data and pose data. For example, for a handle 501 of cylindrical configuration, the point of projection may be the intersection of an extension of the central axis of the handle 501 and the plane of the display 275. Such a mapping manner can enable the posture of the handle 501 to directly correspond to a point pointing to the display device 200 when the handle 501 points to the display device 200 according to the use habit of the user when the handle 501 is at a certain distance from the display device 200, and accurately map the point on the display device 200. The position of the mapping point can be changed when the user moves the handle 501 and rotates the handle 501, so that the user can conveniently perform operation.

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

After determining the mapping point location, the controller 250 may also display the operation pattern in real time according to the mapping point location. In order to distinguish the operation patterns of the different handles 501, the color and/or pattern shape of the manipulation pattern displayed by the control 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 serial number 01 is red, the color of the handle corresponding manipulation pattern with serial number 02 is purple, the color of the handle corresponding manipulation pattern with serial number 03 is green, the color of the handle corresponding manipulation pattern with serial number 04 is blue, and the color of the handle corresponding manipulation pattern with serial number 05 is black. The distinct colors are distinguished by different and contrasting colors to display the control patterns corresponding to different handles 501.

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

Obviously, since the operation pattern may include the trace mark and the motion pattern, both the trace mark and the motion pattern may be set at the same time and the trace mark may be adapted to the motion pattern when the color and/or the pattern shape set according to the handle recognition ID. For example, if the handle with serial number 01 corresponds to the pattern with red color, the trace mark is a red circular pattern, and the generated motion pattern can also be adapted to the red circular pattern, for example, during the scribing operation, the formed scribe line is a line with an arc end, the color of the line is also 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 manipulation pattern displayed by the same handle 501 may have various forms. For example, the handle corresponding to the manipulation pattern with the serial number 01 may be a red circle or a yellow pentagram, and may be switched by the user operation to adapt to different background patterns or to different expression intentions.

As can be seen from the above technical solutions, the method for displaying the handle manipulation pattern provided in the above embodiments may be configured in the controller 250 of the display device 200, and implement real-time monitoring of the position and the posture of the handle 501, and mapping the position and the posture in the display area of the display 275, so as to control the display 275 to display the manipulation pattern in real time according to the mapping point position. The colors and/or pattern shapes of the displayed control patterns can be set according to different handles 501, so that the control patterns of different handles 501 can be distinguished. The method can fully utilize the display device 200 to support the multi-handle 501 interaction function, is convenient for different handle 501 operators to execute interaction operation with the display device 200, and provides more diversified and personalized interaction modes.

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

s401: acquiring a starting-up 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 a 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 process, the user may input a power-on command through the control apparatus 100 or through a power-on key on the display device 200. The controller 250, upon receiving the power-on command, may detect the handle identification ID of the access external device interface 240 in response to the power-on command.

Then, the color and/or shape of the manipulation pattern is set for each handle 501 according to the detected handle identification ID, and an information tag (information tab) is created for recording the setting result, that is, the handle identification ID and the color and/or pattern shape of the manipulation pattern corresponding to the handle identification ID are recorded in the information tag. And finally, storing the created information tag for later calling.

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

The information tag of the display apparatus 200 may be power-off without being saved and the handle 501 is reconnected to create the information tag each time it is turned on, thereby reducing the data storage amount and updating the contents recorded in the information tag in time. Obviously, when the display device 200 is powered on, if the handle 501 is powered off and powered on again, after the display device 200 obtains the information that the handle 501 is connected to the external device interface 240, the display device 200 may search the handle identification ID, and search the recorded serial number and the information such as the color and shape of the control pattern in the previously stored information tag, so as to determine the color and shape of the control pattern corresponding to the handle identification ID quickly.

In the above embodiment, since the display device 200 can support an unlimited number of handles 501 to be accessed, the display device 200 needs to set its manipulation pattern for each accessed handle 501 to be distinguished from each other. Accordingly, in some embodiments, the step of setting a color and/or pattern shape of a 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 different manipulation patterns to each handle 501, when setting the color of the manipulation pattern for each handle 501 connected to the external device interface 240, the primary color data may be generated first, and then the colors of the primary color data generated manipulation patterns may be combined, so as to generate the color of the handle 501 corresponding to the manipulation pattern. The primary color data includes three random numbers between 0 and 255, which are respectively used to represent RGB three primary color values of the manipulation pattern, that is, the color corresponding to each handle 501 is used as the corresponding RGB three primary colors of the manipulation pattern color in a manner of obtaining three random numbers between 0 and 255, and the color of the manipulation pattern can be determined after the values of the three primary colors are determined.

Obviously, when setting the color of the manipulation pattern, the colors of the different handles 501 should be different, and therefore the obtained cubic random number cannot be the same as the colors of the other handles already set. That is, after obtaining the random number three times, the color of the manipulation pattern recorded in the stored information tag may be compared once, and if the generated color of the manipulation pattern is the same as the color of any one of the recorded manipulation patterns of the handle 501, the random number is generated three times again until the manipulation pattern of the handle 501 is set to another color.

It should be noted that, in order to avoid that the set manipulation pattern color is the same as other set manipulation pattern colors, in the range of 0 to 255 where the cubic random number is obtained, the primary color values of the set colors corresponding to one or more primary colors may be deleted, so that primary color data different from the set colors is directly obtained, and different manipulation pattern colors are generated.

Similarly, the setting of the shape of the control pattern can also be completed by selecting 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 the serial number of the handle 501 is determined, the corresponding control pattern shape is determined directly according to the serial number.

As can be seen from the above technical solutions, in the above embodiments, by storing the information tag in the display apparatus 200, the handle 501 accessing the external device interface 240 can be managed in a unified manner, and can be queried by an application program, so as to implement interaction between a plurality of handles 501 and the display apparatus 200.

In order to connect a larger number of handgrips 501 and adapt to the positioning manner of a part of the handgrips 501, in some embodiments of the present application, a positioning base station 502 is connected to the external device interface 240, so that the plurality of handgrips 501 access the external device interface 240 through the positioning base station 502. The positioning base station 502 is a device that cooperates with the handle 501 for positioning the handle 501. Thus, the positioning base station 502 may have the same signal detection principle as the handpiece 501, such as positioning principles both based on laser or ultrasound.

For example, for a portion of the handle 501, the positioning base station 502 may perform scanning by sending a particular form of laser signal in different directions. The handle 501 in the scanning range can 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, thereby positioning 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 attitude data detected by components such as a gravitational acceleration sensor and a gyroscope in the handle 501. Also, upon receiving the attitude data, the positioning base station 502 may combine the attitude data with the position data detected in the same period of time, thereby uniformly transmitting to the display apparatus 200.

The positioning base station 502 may be located in a position that facilitates scanning to the handle 501. The positioning base station 502 is fixed in position relative to the display 275 and the controller 250 can obtain relative position information. The positioning base station 502 may be fixed around the display 275, for example, in a central position on top of the display 275. At this time, the distance and the deviation 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 coordinate of a mapping point according to the three-dimensional position coordinate, the width value and the horizontal attitude angle;

s204: and calculating the vertical coordinate of the mapping point according to the three-dimensional position coordinate, the height value and the vertical attitude angle.

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 handpiece 501 and ultrasound/laser information received by the handpiece 501 from the positioning base station 502. The attitude data may include the tilt angle of the handle 501 with respect to the horizontal direction and the numerical direction, represented by the horizontal attitude angle α and the vertical attitude angle β, respectively.

Meanwhile, as shown in fig. 8, the controller 250 may further obtain a width value and a height value of the display 275, and obtain 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., the screen size, may be determined according to display apparatuses 200 of different specifications. For example, the 65 inch smart television has a width value of 1480mm and a height value of 897 mm. The distance value D is determined according to the placement position of the positioning base station 502.

After acquiring the above data, the controller 250 may map the position data and the pose 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 the expression of the mapping point position, a rectangular coordinate system is constructed on the plane of the display 275 with the lower left corner of the display 275 as the origin, and the mapping point position is represented in the rectangular coordinate system, i.e., the mapping point position coordinate is P (lcd _ w, lcd _ h).

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

lcd_w＝(x*tanα+W/2+y)；

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

as shown in fig. 10, the vertical coordinate of the mapping point may be calculated from the three-dimensional position coordinate, the height value, and the vertical posture angle. That is, the vertical coordinate of the mapping point:

Lcd_h＝H-(-z-D-tanβ*x)；

in the formula, Lcd _ h is a 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 coordinate; z is a vertical z-axis coordinate in the three-dimensional position coordinate; d is a distance value between the positioning base station and the display; beta is the vertical attitude angle.

In this embodiment, it can be seen that the position coordinates of the intersection point of the extension line of the central axis of the handle 501 and the plane of the display 275 can be determined through the space geometric relationship, so as to determine the position of the mapping point. It should be noted that, along with the operation of the user, an intersection point of an extension line of the central axis of the handle 501 and the plane of the display 275 may exceed a display area range, and at this time, the display control pattern may be fixed at an edge position when the display area is exceeded. After calculation by the above formula, if lcd _ H is negative or greater than H, the lcd _ H exceeds the range of the display 275, and the control pattern can be displayed at the edge position adjacent to the exceeding direction; if lcd _ W is negative or greater than W, beyond the range of the display 275, a steering pattern may be displayed at the edge location adjacent in the over direction.

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 the tracking mark, so that the user can determine the position of the interactive control point conveniently; on the other hand, the action pattern can be displayed when the user performs a part of the interactive operation.

For example, when the user performs a line drawing operation, the user may start to draw a line by pressing a key of the handle 501 corresponding to the function. And moves the position of the handle 501 or changes the posture of the handle 501 to continue forming a line. And after reaching a specific position, releasing the key to finish scribing.

For example, in some embodiments of the present application, the step of controlling the display to display a manipulation pattern in real time according to the mapping 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, a user can input various operation actions through the handle 501, and the handle 501 can convert the operation actions into operation information and send the operation information and pose information to the display device 200. Therefore, the controller 250 can acquire the operation information input by the user through the handle 501, and then create and store an input tag (InputInformTab) according to the operation information. And the input label records mapping point positions corresponding to the handle identification ID, the key identification serial number, the key event data and the pose information in the operation information.

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

Where InputInformmTab may be a circular queue of size 65536. Taking Linux/android system as an example, when the display device 200 receives the operation information of the handle 500, the "send _ event" function may be called, and the type parameter is "EV _ MSC", the code parameter is "MSC _ RAW", and the value parameter is the latest recorded sequence number in Inp utInformTab among 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 application, 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 to distinguish the operations of the multiple handles 501, so as to prevent confusion of the operation events of the multiple handles 501.

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

s321: calling the input label;

s322: displaying a tracking mark for tracking the position of the mapping point on a first layer in real time according to the handle identification ID in the input label and the position of the mapping point;

s323: drawing an action pattern on a second map 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 tag may be called by an application program to generate a tracking mark and an action pattern, respectively. 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 comprehensively determined and generated according to the handle identification ID, the key identification serial number, the key event data and the mapping point position in the input label.

For example, the application software queries that the information stored in the InputInformTab and/or the informationTab includes a handle identification ID, a color or shape of a manipulation pattern, a key identification serial number, key event data, and a mapping point position, and draws an action pattern. Such as extracting the pressed position and the lifted position in the case event data and determining the scribing line locus by mapping the position change of the point between the two positions, thereby forming a line pattern, as shown in fig. 11.

In the displaying process, the application software of the display device 200 may set, for each handle 501, two corresponding layers (surfaces) in the surfflinger when using the information transmitted by the handle 501. One corresponding pose tracks the position pointed by the handle, namely the display of the tracking mark is finished on the first image layer; and the other one corresponds to operation patterns such as circles, mark symbols and the like, namely the action patterns are displayed on the second layer. Finally, the layer composition is performed in real time as needed in the surfefl inger service and displayed on the display 275.

It can be seen that, in the above embodiment, two layers may be set for each handle 501 to respectively display the tracking mark and the action pattern, so that no specific interaction is affected on the tracking of the action, and independent layers are correspondingly set for the visualization operation of each handle, thereby avoiding the influence between the interactions of the handles 501.

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

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: and hiding the first layer and the second 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 other handles are located is hidden. When the content of the mark is too much, the surfefringer is controlled not to 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 authorities, that is, for the handle with higher authority, all layers corresponding to the handle with lower priority display request authority can be hidden through the key instruction with priority display. The handle with lower authority can not hide the layers corresponding to other handles with authority higher than that of the handle, and can only hide the layers corresponding to other handles with authority lower than that of the handle.

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, and the like may be input through the handle keys, and the controller 250 of the display apparatus 200 may complete the corresponding functions by executing the control program after receiving the corresponding instructions.

Based on the above-mentioned handle manipulation pattern display method, some embodiments of the present application further provide a display apparatus 200, which includes 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, posture data and handle identification ID of the handle;

s2: calculating the position of a mapping point of the handle on the display according to the current position data and the posture 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 the pattern shape of the control pattern are set according to the handle identification ID.

By performing the above steps, the controller 250 can realize that the user performs diversified and personalized interaction through the handle 501. The display device 200 may be used as a fixed location public screen for multiple people simultaneously.

For example, when a conference discussion is performed by using the display device 200, when a person participating in the discussion needs to point out a certain part of the content displayed, the pointing motion can be completed by using the pose tracking handle 501, the controller 250 determines the mapping point position on the display 275 according to the pose information corresponding to the pointing motion, and then, by pressing a key of the handle 501, operations such as circle drawing, mark symbol marking and the like are implemented at the selected position, so as to add a mark to the content of the discussion.

The display device 200 can make full use of the function of the supported pose tracking handle 501, so that the participants of each conference can conveniently point out their attention points on the current display content to express their viewpoints without affecting the expression of the main viewpoints of the main personnel during conference discussion.

As can be seen from the above technical solutions, the display apparatus 200 provided in 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 the position data and the 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 can interact with the handle 501 to provide more diversified and personalized interaction modes.
