Description

Technical Field

[0001] This invention relates to the field of performance assistance methods, and in particular to a performance assistance device, method, and application. Background Technology

[0002] During film and television shooting, there are scenes involving driving vehicles or piloting airplanes, which require actors to manipulate control sticks. These scenes often need to convey a tense atmosphere, thus requiring actors to display strained expressions and tense muscles when operating the control sticks.

[0003] Generally, the control levers used as props have low connection strength to vehicles or airplanes to facilitate actors' pushing and pulling. Actors tend to be relaxed when operating the levers, so portraying strained expressions and tense muscles requires a high level of acting skill. The low connection strength also makes it easy for actors to make mistakes while operating the levers, leading to over-rotation and making them unsuitable for the needs of the filming plot.

[0004] This resulted in lower performance quality, a high rate of retakes during filming, and excessively high demands on the actors' acting skills. Summary of the Invention

[0005] Therefore, it is necessary to provide a performance assistance device, method, and application to address the problems of low shooting efficiency and high NG rate in joystick scenes.

[0006] A performance aid device, comprising:

[0007] A joystick for the actor to grip;

[0008] A push-pull path transmission device, used to generate or receive trajectory change setting data; and

[0009] A motor drive unit is electrically connected to the push-pull path transmission device and transmits power to the control lever;

[0010] The motor drive device acquires trajectory change setting data through the push-pull path transmission device. When the actor pushes or pulls the control stick, the motor drive device makes the control stick overcome the pushing or pulling force applied by the actor, and controls the control stick to move according to the trajectory change setting data.

[0011] The motor drive device of the present invention includes a first motor, a first gear, a second motor, and a second gear. The first gear is mounted on the motor shaft of the first motor, and the second gear is mounted on the motor shaft of the second motor. The control lever is transmitted to the second gear so that the second gear can drive the control lever to rotate. The second motor is connected to the first gear so that the first gear can drive the control lever to rotate. The axis of the first gear is perpendicular to the axis of the second gear.

[0012] The motor drive device of the present invention further includes a translation unit and / or a lifting unit, wherein the first motor is connected to the translation unit and / or the lifting unit so that the translation unit can drive the control lever to produce a horizontal displacement, and / or the lifting unit can drive the control lever to produce a vertical displacement.

[0013] The present invention also includes an operating platform, wherein an installation chamber is provided inside the operating platform, the motor drive device is installed in the installation chamber, an movable hole communicating with the installation chamber is provided on the operating platform, the control lever passes through the movable hole, and a flexible shielding cloth is provided between the edge of the movable hole and the side wall of the control lever.

[0014] The trajectory change setting data of the present invention includes a first rotation data group and a second rotation data group. The trajectory change setting data also includes a displacement data group and / or a lifting data group. The first motor only acquires the first rotation data group, the second motor only acquires the second rotation data group, the translation unit only acquires the displacement data group, and / or the lifting unit only acquires the lifting data group.

[0015] The translation unit and / or the lifting unit described in this invention are electric push rods.

[0016] A performance assistance method, comprising:

[0017] The push-pull path transmission device generates or receives trajectory change setting data and transmits the trajectory change setting data to the motor drive device.

[0018] The motor drive unit controls the joystick movement based on the data set according to the trajectory changes.

[0019] When the actor pushes or pulls the joystick, the motor drive provides additional force to the joystick so that it overcomes the force applied by the actor, thus ensuring that the joystick's movement always matches the trajectory change settings.

[0020] An application of a performance aid device for filming scenes where actors need to control a joystick.

[0021] When a scene depicting a broken joystick needs to be filmed, the present invention provides that the translation unit and / or the lifting unit controls the joystick to translate or lift, and the first motor and / or the second motor controls the joystick to rotate.

[0022] An application of a performance assistance device in which a motor drive device controls the movement of a joystick when the actor is not in contact with it, in order to film an autonomous driving scene.

[0023] The beneficial effects of this invention are as follows:

[0024] In scenes where actors manipulate joysticks, the joysticks can move according to a fixed motion equation that conforms to the trajectory change setting data under the control of the motor drive device, so that they are in a specific position at each specific point in time, thus making the movement of the joysticks conform to the needs of the filming plot.

[0025] The motor drive unit controls the joystick to switch positions in a step-by-step manner. Therefore, the joystick is subject to the self-locking effect of the motor drive unit in each position. The force applied by the actor to the joystick cannot drive the joystick to switch positions. Thus, the actor can apply a larger force to the joystick, so that the actor's facial expressions and muscle states can be more natural and in line with the filming plot. On the one hand, it reduces the requirements for the actor's acting skills during the filming process, and on the other hand, it reduces the NG rate and improves the filming efficiency.

[0037] Example 1:

[0038] See Figure 1 This embodiment provides a performance assistance device, including a joystick 3, a push-pull path transmission device 1, a motor drive device 2, and an operating platform 4.

[0039] The joystick 3 is a performance prop used by actors to grip and pull during the performance. In this embodiment, the shape and design of the joystick 3 can closely resemble or reference the shape of the joystick 3 in actual vehicles or aircraft. The joystick 3 is generally mounted on the control console 4, which can simulate the environment in the cockpit of a vehicle or aircraft. The joystick 3 can be moved on the control console 4 according to the needs of the filming plot.

[0040] It is particularly important to note that the joystick 3 has a degree of freedom of movement on the control unit 4, including but not limited to translation, lifting, or rotation, as long as it meets the needs of the filming plot.

[0041] Unlike existing technologies, in this embodiment, the movement of the joystick 3 is not controlled by the actor, but rather the motor drive device 2 transmits power to the joystick 3, and the joystick 3 is controlled by the motor drive device 2. The motor drive device 2 uses a large number of variable frequency servo motors, so the operation of the motor drive device 2 can be precisely controlled by a program.

[0042] According to the needs of the filming plot, the joystick 3 needs to be in a specific position at each moment during filming. Utilizing the self-locking capability of the variable frequency servo motor, the motor drive device 2 can keep the joystick 3 in a specific position at a specific moment. The motor drive device 2 applies additional force to the joystick 3 to counteract external forces that might interfere with its position, such as the force applied by an actor. Furthermore, during the position switching between different filming moments, the variable frequency servo motor can adjust its parameters according to the force applied by the actor, ensuring that the joystick 3 switches positions at a predetermined speed, thus conforming to the filming plot.

[0043] Therefore, the movement of the joystick 3 in this embodiment is entirely controlled by the motor drive device 2 and is not affected by the actor's control. Thus, the operation of the joystick 3 can perfectly meet the needs of the shooting plot, effectively improve the shooting quality, and reduce the number of reshoots caused by the joystick 3 not meeting the requirements.

[0044] Furthermore, since the force applied by the actor to the joystick 3 does not affect the movement of the joystick 3, the actor can apply a greater pushing and pulling force to the joystick 3, thereby keeping their muscles in a more tense state and making it easier to control their facial expressions, thus creating a more tense shooting atmosphere. On the one hand, the shooting quality is improved, and on the other hand, the requirements for the actor's acting skills are reduced, thus reducing shooting costs and NG rate.

[0045] The operation of the motor drive unit 2 is provided by the push-pull path transmission device 1. Specifically, the motor drive unit 2 is electrically connected to the push-pull path transmission device 1. The push-pull path transmission device 1 generates or receives trajectory change setting data and transmits the trajectory change setting data to the motor drive unit 2. The motor drive unit 2 controls the joystick 3 to move according to the trajectory change setting data. The trajectory change setting data is the correspondence between the position state of the joystick 3 and the shooting time according to the needs of the shooting plot.

[0046] In some other embodiments, the push-pull path transmission device 1 can automatically generate trajectory change setting data through a script. In this embodiment, however, the push-pull path transmission device 1 is a programmable controller that obtains trajectory change setting data from the UE.

[0047] See Figure 3 Correspondingly, this embodiment provides a performance assistance method, which is based on the aforementioned performance assistance device and specifically includes the following steps:

[0048] Step S1: Push-pull path transmission device 1 generates or receives trajectory change setting data. The trajectory change setting data is the position state that the joystick 3 should correspond to at different shooting times. Push-pull path transmission device 1 transmits the trajectory change setting data to motor drive device 2.

[0049] Step S2: The motor drive device 2 controls the movement of the joystick 3 according to the trajectory change setting data, so that the joystick 3 moves according to the trajectory change setting data, so that the joystick 3 is in a specific position at a specific shooting time.

[0050] During filming, when the actor pushes or pulls the joystick 3, the motor drive device 2 provides additional force to the joystick 3, so that the joystick 3 can overcome the force applied by the actor and ensure that the joystick 3 can still move according to the trajectory change set data.

[0051] In some embodiments, the motor drive device 2 includes a first motor 21 and a first gear 22. The first gear 22 is mounted on the motor shaft of the first motor 21. The control lever 3 is transmitted to the first gear 22. The first motor 21 controls the control lever 3 to rotate through the first gear 22. The control lever 3 is perpendicular to the axis of the first gear 22, and the extension line of the control lever 3 passes through the center of the first gear 22. Therefore, the rotation surface of the control lever 3 is perpendicular to the motor shaft of the first motor 21.

[0052] See Figure 2 Depending on the shooting scene, the object that the joystick 3 needs to simulate will also be different. In order to expand the application range of the performance assistance device, the motor drive device 2 in this embodiment also includes a second motor 23 and a second gear 24. The second gear 24 is mounted on the motor shaft of the second motor 23. The joystick 3 is driven by the second gear 24 so that the second gear 24 can drive the joystick 3 to rotate, and the joystick 3 can rotate around the axis of the second gear 24. The second motor 23 is connected to the first gear 22 so that the first gear 22 can drive the joystick 3 to rotate, and the joystick 3 can also rotate around the axis of the first gear 22, wherein the axis of the first gear 22 is perpendicular to the axis of the second gear 24. The cooperation of the first gear 22 and the second gear 24 gives the joystick 3 two degrees of rotational freedom, thereby expanding the shooting scenes that the performance assistance device can be applied to.

[0053] Example 2:

[0054] This embodiment provides an application of a performance assistance device, specifically in a filming scenario where the actor needs to control a joystick.

[0055] Specifically, in certain shooting scenarios, it is necessary to depict a scene where the joystick breaks. Therefore, the motor drive device in this embodiment further includes a translation unit and a lifting unit. There are two translation units: a first translation unit and a second translation unit. The first translation unit, the second translation unit, and the lifting unit are connected sequentially. The first motor is connected to the lifting unit, thereby allowing the first translation unit to control the joystick to move along the x-axis, the second translation unit to control the joystick to move along the y-axis, and the lifting unit to control the joystick to move along the z-axis. This gives the joystick both translational and lifting freedom.

[0056] The control panel has a movable hole through which the control lever passes. Under normal circumstances, the control lever only has rotational freedom. However, when the translation unit and the lifting unit control the control lever to translate and lift, the control lever can extend or retract into the movable hole. In conjunction with the first motor and / or the second motor, this produces an abnormal rotational state. As a result, when the actor pushes or pulls the control lever, it creates the visual effect of the control lever breaking.

[0057] Therefore, one specific application scenario of the performance assistance device in this embodiment is a shooting scenario where the joystick breaks.

[0058] Of course, the aperture of the movable hole is relatively large to accommodate the movement of the joystick. To prevent the actual control method of the joystick from being captured on camera, a mounting chamber is provided inside the operating platform. The motor drive device is installed in the mounting chamber, and the movable hole is connected to the mounting chamber. A flexible shielding cloth is provided between the edge of the movable hole and the side wall of the joystick.

[0059] More specifically, both the translation unit and the lifting unit are electric push rods, and the motors used inside are servo frequency conversion motors, thus achieving a similar technical effect to the first motor and the second motor. Further details will not be elaborated in this embodiment.

[0060] Since the degrees of freedom of operation of the first motor, the second motor, the translation unit, and the lifting unit are independent of each other in this embodiment, the trajectory change setting data is divided into a first rotation data group, a second rotation data group, a displacement data group, and a lifting data group. The first motor only acquires the first rotation data group, the second motor only acquires the second rotation data group, the translation unit only acquires the displacement data group, and the lifting unit only acquires the lifting data group, so that the first motor, the second motor, the translation unit, and the lifting unit can independently control the activity state of the joystick according to their respective required data.

[0061] Example 3:

[0062] The difference between this embodiment and embodiment 2 is that, when the actor does not need to touch the joystick, the motor drive device controls the joystick to move in order to shoot the autonomous driving scene.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
