In some embodiments, fig. 1 is a schematic structural diagram of a vehicle-mounted wearable display system provided in an embodiment of the present disclosure. As shown in fig. 1, the system includes: the vehicle-mounted display device comprises a vehicle machine 10, a vehicle-mounted wearable display device 11 and a controller 12; the controller 12 sends the pose data to the vehicle machine; the vehicle-mounted wearable display device 11 sends the trigger surface data to the vehicle machine 10; the vehicle machine 10 is configured to determine a positive direction of the controller 12 based on the pose data and the trigger surface data.
An infinite trigger surface, which may also be referred to as a display field of view screen and may be represented by trigger surface data, is provided in the vehicle-mounted wearable display device 11. The vehicle-mounted wearable display device 11 sends the trigger surface data to the vehicle machine 10, and correspondingly, the vehicle machine 10 receives the trigger surface data.
Wherein after the controller 12 is worn by the user, the pose of the controller is determined, which can be characterized by pose data. The controller 12 sends its own pose data to the in-vehicle machine 10, and correspondingly, the in-vehicle machine 10 receives the pose data.
The car machine 10 determines the direction in which the controller 12 points to the trigger surface as the positive direction of the controller 12 based on the received pose data and the trigger surface data, so as to respond to the operation of the user based on the controller 12, change or switch the picture displayed by the wearable display device 11, and realize human-computer interaction.
Illustratively, the pose data may include spatial coordinate information of the controller and the trigger surface data may include spatial coordinate information of the trigger surface, such that the in-vehicle machine 10 may determine the positive direction of the controller 12 based on the spatial coordinate relationship.
The on-vehicle wearable display system that this disclosed embodiment provided includes: the vehicle-mounted device 10, the vehicle-mounted wearable display device 11 and the controller 12 acquire pose data of the controller 12 and acquire trigger surface data of the vehicle-mounted wearable display device 11 through the vehicle-mounted device 10, and can automatically determine the positive direction of the controller 10 by using a built-in software program based on the pose data and the trigger surface data. Therefore, after the user takes the controller 12, the vehicle machine 10 can be directly worn without being in the forward direction of the worn front area, after the user wears the controller 12, namely under the condition that the pose of the controller 12 is determined, the vehicle machine can directly determine the forward direction of the controller according to the pose data and the triggering surface data, the vehicle machine is simple and convenient, the user experience can be improved, and the vehicle machine can be suitable for various different wearing modes.
In some embodiments, fig. 2 is a schematic structural diagram of a controller of a vehicle-mounted wearable display device provided in an embodiment of the present disclosure, and fig. 3 is a schematic application scenario diagram of the controller of the vehicle-mounted wearable display device provided in an embodiment of the present disclosure. On the basis of fig. 1, referring to fig. 2 and 3, the controller 12 includes: a controller main body 120, a circuit board 121, and an inertia measurement unit 122; the controller main body 120 includes an operation plane for sensing a control operation of a user; the circuit board is used for responding to the control operation of a user, generating an operation signal and transmitting the operation signal to the car machine 10; the inertial measurement unit 122 is provided on the circuit board 121, and is configured to detect an attitude angle and an acceleration of the controller 12 to generate pose data; the plane of the circuit board 121 and the operating plane form a first predetermined included angle (not shown), and the reference plane of the inertia measurement unit 122 and the plane of the circuit board 121 form a second predetermined included angle (not shown).
The circuit board 121 may generate an operation signal in response to a control operation of the user, and transmit the operation signal to the car machine 10, so that the car machine 10 generates a display control instruction based on the operation signal to control the wearable display device 11 to display.
Based on the above, when the user presses the operation plane, the operation plane senses the pressing operation of the user, and performs electrical conversion based on a response principle, such as a pressure signal, a capacitance-inductance signal or an optical signal, to generate a corresponding electrical signal; further, the circuit board 121 generates an operation signal based on the electrical signal, that is, based on the electrical signal corresponding to the control operation of the user, and transmits the operation signal to the in-vehicle device 10, for example, a processor therein, and the processor in the in-vehicle device 10 performs signal processing based on the received operation signal, so as to implement display control on the in-vehicle wearable display device 11.
Further, an inertial measurement unit 122 is provided on the circuit board 121, and the inertial measurement unit 122 is capable of detecting the attitude angle and acceleration of the controller 12 based on the detection of the attitude angle and acceleration thereof to generate attitude data of the controller 12.
The operation plane and the circuit board 121 form a first preset included angle, and the reference plane of the inertia measurement unit 122 and the plane where the circuit board 121 is located form a second preset included angle, so that on the basis that the inertia measurement unit 23 detects the attitude angle and the acceleration of the reference plane of the inertia measurement unit, the first preset included angle and the second preset included angle are combined to perform spatial angle and spatial coordinate transformation, and the attitude angle and the acceleration of the controller 12 can be obtained, that is, the attitude data of the controller 12 can be obtained.
It can be appreciated that the first predetermined included angle and the second predetermined included angle may be the same or different. If the first preset included angle is the same as the second preset included angle, the pose data measured by the inertia measurement unit 122 can be directly used for acquiring the pose of the controller; if the first preset included angle and the second preset included angle are different, based on the pose data measured by the inertial measurement unit 122, the pose of the controller 12 can be obtained by performing spatial angle and spatial coordinate transformation according to the first preset included angle and the second preset included angle.
In some embodiments, fig. 4 is a schematic side view of a controller of a vehicle-mounted wearable display device according to an embodiment of the present disclosure. Referring to fig. 2 and 4, the first predetermined angle and the second predetermined angle are both 0 degrees, that is, the circuit board 22 is parallel to the operation plane 24, and the reference plane of the inertial measurement unit 122 is parallel to the circuit board 121, so that the reference plane of the inertial measurement unit 122 is also parallel to the operation plane of the controller 12.
Based on this, on the basis that the inertial measurement unit 122 detects the attitude angle and the acceleration of the self reference surface, due to the parallel relationship, the attitude angle and the acceleration of the operation plane of the controller 12, that is, the attitude data of the controller 12 can be directly determined without angle transformation, so that the detection mode is simple, convenient and high in accuracy.
In some embodiments, the controller 12 may be in the shape of a ring (as shown in fig. 4), a bracelet, or other shape having a wearable structure, but is not limited thereto.
Based on any one of the vehicle-mounted wearable display systems in the above embodiments, the embodiment of the present disclosure further provides a positive direction determination method for a controller of a vehicle-mounted wearable display device, and the method can be applied to any one of the vehicle-mounted wearable display systems, so as to automatically determine the positive direction of the controller based on the pose of the controller.
In some embodiments, fig. 5 is a schematic flowchart of a positive direction determination method of a controller of a vehicle-mounted wearable display device according to an embodiment of the present disclosure, where the determination method is executed by a vehicle-mounted device. As shown in fig. 5, the determination method includes:
s401, pose data and trigger surface data are obtained.
S402, determining the positive direction of the controller based on the pose data and the trigger surface data.
Specifically, the pose data includes attitude angle and acceleration data of the controller, which contains spatial coordinate information of the controller; the trigger surface data is screen data of a display field of view, and includes spatial coordinate information of the trigger surface.
In combination with the above, the controller sends the pose data to the car machine, and correspondingly, the car machine receives the pose data, so that the car machine acquires the pose data; and the vehicle-mounted wearable display device sends the trigger surface data to the vehicle machine, and correspondingly, the vehicle machine receives the trigger surface data, so that the vehicle machine acquires the trigger surface data.
Based on the method, the vehicle machine processes the acquired pose data and the acquired trigger surface data, and the positive direction of the controller can be determined.
The positive direction judgment method of the controller of the vehicle-mounted wearable display device can be executed by a vehicle machine, specifically, the positive direction of the controller is determined based on pose data and trigger surface data by acquiring the pose data and the trigger surface data, so that when a user takes the controller, the user can directly wear the controller without distinguishing directions based on the appearance of the controller before wearing the controller, and then the vehicle machine acquires the pose data of the controller and combines the pose data and the trigger surface data of the controller, so that the positive direction of the controller can be automatically determined, the method is simple and convenient, the user experience can be improved, and the method can be suitable for various different wearing modes.
In some embodiments, fig. 6 is a flowchart illustrating a positive direction determination method for a controller of another vehicle-mounted wearable display device according to an embodiment of the present disclosure. With reference to fig. 5 and 6, determining the positive direction of the controller based on the pose data and the trigger surface data in S402 includes:
s4021, determining data of the trigger line to be displayed, which is controlled by the controller, based on the pose data.
The trigger lines to be displayed comprise two trigger lines which take the controller as a starting point and are in antiparallel.
Illustratively, fig. 7 is an orientation diagram of a trigger line to be displayed associated with a controller according to an embodiment of the present disclosure. Referring to fig. 7, or referring to fig. 2, the trigger line to be displayed includes two trigger lines that are respectively emitted in two parallel and opposite directions with the controller 12 as a starting point, that is, the two trigger lines are antiparallel, that is, the two trigger lines are on a straight line, but opposite directions.
Illustratively, in conjunction with the above, a circuit board 121 is disposed inside the controller 12, and an inertial measurement unit 122 is disposed on the circuit board 121, wherein a reference plane of the inertial measurement unit 122 is parallel to a plane where the circuit board 121 is located, and is parallel to an operation plane of the controller 12. Based on this, when the trigger line set in the software program in the in-vehicle machine is generated using a plane parallel to the reference plane of the inertial measurement unit 122, a bundle of trigger lines to be displayed that passes through the controller 12 and is parallel to the operation plane of the controller 12 can be displayed in the display view screen of the on-vehicle wearable display device 11.
However, in the related art, the trigger lines displayed in the display view frame are usually bidirectional, that is, both of the two trigger lines to be displayed are displayed, which does not meet the requirement of interactive operation. During the interaction, it is necessary to send a single-sided trigger line from the controller 12, that is, one display is selected from the two trigger lines to be displayed, so it is necessary to determine and display the trigger line to be displayed in the same direction as the positive direction of the controller, so as to implement human-computer interaction.
In view of this, the embodiment of the present disclosure provides the determination method. Specifically, the car machine 10 processes the pose data sent by the controller 12, and controls the on-vehicle wearable display device 11 to display only one of the two trigger lines to be displayed, specifically, to display the trigger line in the same direction as the positive direction of the controller 12, where a specific processing manner is exemplarily described later.
Thus, by processing the pose data of the controller, it is possible to determine the data of the two trigger lines to be displayed emitted by the controller, i.e. to enable the determination of the data of the trigger lines to be displayed associated with the controller based on the pose data.
It will be appreciated that although the two anti-parallel trigger lines to be displayed are shown in figure 7, they are not displayed until the display control instructions are generated; but after generating the display control instructions; the trigger line in the same direction as the positive direction of the controller is displayed by the vehicle-mounted wearable display device.
S4022, based on the data of the trigger line to be displayed and the data of the trigger surface, judging that the target trigger line to be displayed meeting the preset conditions is the trigger line to be displayed corresponding to the positive direction of the controller.
The preset condition is used for judging whether the target trigger line to be displayed is a trigger line to be displayed corresponding to the positive direction of the controller, and if the preset condition is met, the target trigger line to be displayed is the trigger line to be displayed corresponding to the positive direction of the controller; if the preset condition is not met, it is determined that the target trigger line to be displayed is not a trigger line to be displayed corresponding to the positive direction of the controller, specifically, the target trigger line to be displayed is a trigger line to be displayed corresponding to the negative direction of the controller.
The target trigger line to be displayed is one of the trigger lines to be displayed.
Therefore, whether the target trigger line to be displayed is the trigger line to be displayed corresponding to the positive direction of the controller can be judged based on the data of the trigger line to be displayed and the data of the trigger surface in combination with preset conditions.
S4023, determining the positive direction of the controller based on the orientation of the trigger line to be displayed corresponding to the positive direction of the controller.
Specifically, the orientation of the trigger line to be displayed corresponding to the positive direction of the controller is the same as the orientation of the positive direction of the controller. Thus, after the trigger line to be displayed corresponding to the positive direction of the controller is determined in S4022, the positive direction of the controller can be determined based on the trigger line to be displayed corresponding to the positive direction of the controller.
Illustratively, fig. 8 is a schematic orientation diagram of a trigger line to be displayed, which corresponds to a positive direction of the controller according to an embodiment of the present disclosure. As shown in fig. 8, or as shown in fig. 2, the trigger lines to be displayed that correspond to the positive direction of the controller can be used to indicate the positive direction of the controller, shown in the Y direction.
In some embodiments, the preset conditions include: the trigger line is in contact with the trigger surface.
The trigger line is determined based on data of the trigger line to be displayed, and the trigger surface is determined based on the data of the trigger surface.

Wherein, can confirm the trigger line that waits to show that corresponds based on waiting to show the data of trigger line, can confirm the trigger face that corresponds based on the data of trigger face, after confirming waiting to show trigger line and trigger face, can judge, specifically: judging whether the trigger line to be displayed contacts the trigger surface; and further, based on the judgment result, the trigger line to be displayed corresponding to the positive direction of the controller is determined. Specifically, if the target trigger line to be displayed is in contact with the trigger surface, it may be determined that the target trigger line to be displayed in contact with the trigger surface is a trigger line to be displayed corresponding to the positive direction of the controller. Thereby, a trigger line to be displayed corresponding to the positive direction of the controller is obtained.
Illustratively, with reference to fig. 7 and 8, for an example of a vehicle VR display with a controller as a ring, the method may include:
set up an unlimited trigger face in the sky box in VR field of vision the place ahead, the ring has two antiparallel trigger lines, and only one in these two trigger lines can contact with the trigger face, the positive direction of controller is confirmed with the pointing to of this trigger line that the trigger face contacted, thereby the direction that does not have the trigger line that contacts with the trigger face is confirmed as the reverse direction of controller, in the follow-up display process, only show the trigger line who instructs the positive direction, and the trigger line who instructs the reverse direction does not show.
Furthermore, when the user takes off the ring and rotates the ring by 180 degrees, the trigger line which is not originally in contact with the trigger surface in the two trigger lines of the ring is in contact with the trigger surface, so that the direction of the trigger line is determined as the positive direction; the activation line, which was originally in contact with the activation surface, is now no longer in contact with the activation surface, so that its orientation is considered to be the opposite direction.
