As Figure 1 shown, this method can be applied to a system architecture composed of a terminal 110 and a server 120, where the terminal 110 and the server 120 are connected through a network.

Wearable devices include: smart watches, smart bracelets, smart earphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart ankle chains, etc.), smart wristbands, smart clothing, etc. Among them, vehicle user equipment may also be referred to as vehicle terminal, vehicle controller, vehicle module, vehicle component, vehicle chip, or vehicle unit, etc.

[0044] It should be understood that the above terminal 110 and server 120 are only examples, and other existing or future possible implementation manners of other terminals or servers that are applicable to the present application should also be included within the protection scope of the present application and are hereby incorporated herein by reference.

[0045] To facilitate understanding of the embodiments of the present application, the interactivity extension technology related to the present application will be described.

[0046] The graphical language Transmit Format (glTF) is an open standard format for transmitting and loading 3D models, aiming to provide a lightweight, efficient, and extensible 3D model format for fast loading and rendering on platforms such as engines and mobile devices. The glTF format supports various 3D model elements including geometries, materials, textures, animations, and scenes. Due to its openness and efficiency, the glTF format has been widely applied in fields such as engines and mobile devices and has become an important 3D model transmission and loading standard.

[0047] Figure 2 A schematic structural diagram of a glTF file is shown. It can be seen that the glTF file includes multiple object nodes.

[0048] For example, a scene is the entry point of a glTF file. A glTF file may store multiple scenes, and each scene contains one or more nodes. A node points to a mesh, a camera, or a skin, and is used to describe various deformations of the node. Mesh: Represents a geometric object in the scene. Camera: Used to define the view configuration for rendering the scene; Skin is bound to an animation. An accessor is used as an abstract source of data and can be accessed by a mesh, a skin, and an animation, and provides geometric data, skin parameters, and animation values that change over time. A material is the appearance object when a geometric object is rendered and is used to define the appearance parameters of the geometric object. Animation: Used to define changes in nodes (such as rotation and translation); Texture: Contains a sampler and an image, which together define how to map the texture to the model. Among them, images are used to locate the picture resources; Sampler: Used to define the sampling and filtering methods of the picture. A buffer view is used to obtain real data from a buffer.

[0049] In the related art, the Moving Pictures Experts Group (MPEG) has performed interactive extensions to glTF and designed relevant standards for interactivity.

[0050] Interactivity is defined based on behaviors, and a behavior includes a trigger node and an action node. Among them, the trigger conditions of the trigger node include collision conditions, proximity conditions, visibility conditions, etc. Among them, actions include haptic feedback actions (i.e., ACTION_SET_HAPTIC), activation actions (ACTION_ACTIVATE), etc.

[0051] However, there is no interactive standard related to haptic signals in the prior art. Therefore, how to describe haptic signals is an urgent problem to be solved.

[0052] Next, in conjunction with the accompanying drawings, the method for generating haptic signals provided in the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0053] Figure 3 is a schematic diagram of a method for generating a haptic signal provided by an embodiment of the present application. As Figure 3 shown, the method 300 includes at least the following parts:

[0054] S310, obtaining signal attenuation information of the haptic signal;

[0055] S320, generating the haptic signal according to the signal attenuation information of the haptic signal.

[0056] In some embodiments, the signal attenuation information of the haptic signal is used to describe the interaction between the haptic source and the avatar (or the object on which the haptic signal is executed). Therefore, the haptic signal can be generated according to the signal attenuation information of the haptic signal.

[0057] In some embodiments, the method can be executed by an electronic device. For example, it can be executed by the terminal 110 of Figure 1 , or it can also be executed by the server 120 of Figure 1 . The present application does not limit this.

[0058] In some embodiments, the signal attenuation information of the haptic signal includes at least one of the following:

[0059] Signal attenuation information related to distance;

[0060] Signal attenuation information related to time;

[0061] Signal attenuation information related to the occluder;

[0062] Signal attenuation information related to the body part;

[0063] Signal attenuation information related to pressure.

[0064] That is, in the embodiments of the present application, when constructing the haptic signal model, the signal attenuation related to at least one of the factors of distance, time, occluder, body part, and pressure is considered, which is beneficial to ensuring that the haptic signal model provided by the embodiments of the present application can more accurately simulate the presentation form of the haptic signal in the real environment and improve the accuracy of the haptic signal model.

[0065] It should be understood that the present application does not limit the type of the haptic signal. For example, the haptic signal can be triggered by vibration, heat energy, wind, rain, etc.

[0066] In some embodiments, the signal attenuation information of the haptic signal is carried in the first object. For example, the first object includes at least one of the following:

[0067] The haptic source object corresponding to the haptic signal, the avatar object corresponding to the haptic signal, the trigger node object corresponding to the haptic signal, the action node object (or trigger action object, i.e., HapticActionNode object) corresponding to the haptic signal, and the occluder object corresponding to the haptic signal.

[0068] In some embodiments, the signal attenuation information of the haptic signal may be carried in the attribute information of the first object.

[0069] It should be understood that the signal attenuation information of the haptic signal may be carried in the same object, or may also be carried in multiple objects. This application does not make any limitations in this regard. For example, some of the information in the signal attenuation information of the haptic signal is carried in the haptic source object, and the remaining information is carried in the action node object.

[0070] In some embodiments, the first object may be a glTF object.

[0071] In some embodiments, when the signal attenuation information of the haptic signal is carried in the trigger action node object, the signal attenuation information of the haptic signal may be carried in the child node of the trigger action node object, for example, carried in the trigger action media object (HapticActionMedia object), where the trigger action media object points to the haptic data file object. For example, the trigger action media object includes the address information of the haptic data file.

[0072] In some embodiments of this application, S310 includes:

[0073] Obtain a first object;

[0074] Perform parsing processing on the first object to obtain the signal attenuation information of the haptic signal.

[0075] In some embodiments, the first object may be obtained locally by the haptic signal generation device, or may also be obtained from other devices, such as obtained from a server, which may be an object storage service platform, or a Network Attached Storage (NAS), etc.

[0076] In some embodiments of this application, S320 includes:

[0077] Render the haptic signal according to the signal attenuation information of the haptic signal.

[0078] In some embodiments, the haptic signal generation device may include a presentation engine that can render the haptic signal according to the signal attenuation information of the haptic signal.

[0079] In some embodiments, the first object is associated with one or more scenes. Rendering the haptic signal may include rendering the haptic signal in the scene associated with the first object.

[0080] For example, in the scene where the first object is located, render the haptic source and the haptic signal execution object (i.e., the avatar), determine the distance between the haptic source and the haptic signal execution object, determine whether there is an occluder between the haptic source and the haptic signal execution object, and then render the haptic signal according to the signal attenuation information related to the distance and the signal attenuation information related to the occluder.

[0081] For another example, in the scene where the first object is located, render the haptic source and the haptic signal execution object (i.e., the avatar), and render the haptic signal according to the trigger time of the haptic signal and the signal attenuation information related to time.

[0082] For still another example, in the scene where the first object is located, render the haptic source and the haptic signal execution object (i.e., the avatar), and render the haptic signals of different body parts of the haptic signal execution object according to the signal attenuation information related to the body parts.

[0083] For yet another example, in the scene where the first object is located, render the haptic source and the haptic signal execution object (i.e., the avatar), and render the haptic signal felt by the haptic signal execution object according to the force of contact or pressure of the haptic signal execution object on the haptic source, in combination with the signal attenuation information related to pressure.

[0084] Hereinafter, in combination with specific embodiments, the specific implementations of the above several signal attenuation information will be described separately.

[0085] Embodiment 1: Signal attenuation information related to distance

[0086] In some embodiments, the signal attenuation information related to distance can be used to characterize the signal attenuation caused by the distance factor. For example, the shock or heat energy caused by an explosion will attenuate as the distance from the explosion center increases.

[0087] In some embodiments, the signal attenuation information related to distance includes but is not limited to at least one of the following:

[0088] A signal attenuation parameter for determining the attenuation amount of the haptic signal;

[0089] An indication of the signal attenuation mode of the haptic signal;

[0090] An enable or disable indication for indicating whether to enable the distance-related signal attenuation information when generating the haptic signal;

[0091] A haptic signal type indication for indicating the type of the haptic signal to which the distance-related signal attenuation information applies.

[0092] Exemplarily, each piece of information in the distance-related signal attenuation information may be carried in at least one of the following objects:

[0093] The haptic source object corresponding to the haptic signal, the avatar object corresponding to the haptic signal, the trigger node object corresponding to the haptic signal, the action node object corresponding to the haptic signal (e.g., carried in a child node of the action node object, such as a trigger action media object).

[0094] In some embodiments, the signal attenuation mode indication of the haptic signal is used to indicate at least one of the following modes:

[0095] Attenuating by a fixed attenuation amount, attenuating based on a preset signal attenuation mode (e.g., based on a preset signal attenuation formula), attenuating based on a custom signal attenuation mode (e.g., based on a custom signal attenuation formula).

[0096] In some embodiments, when there are multiple preset signal attenuation modes, the signal attenuation mode indication of the haptic signal may further indicate the target preset signal attenuation mode among the multiple preset signal attenuation modes, e.g., indicating the target signal attenuation formula among multiple preset signal attenuation formulas.

[0097] In some embodiments, the multiple preset signal attenuation modes include but are not limited to at least one of the following:

[0098] Inverse distance attenuation mode, linear distance attenuation mode, exponential distance attenuation mode, inverse square attenuation mode.

[0099] In some embodiments, for the inverse distance attenuation mode, the following formula (or inverse distance attenuation formula) may be used to determine the feedback strength ida(d, md, rf) of the haptic signal:

[0100]

[0101] Where md is the maximum distance, rf is the attenuation coefficient (roll factor), rd is the reference distance, and d is the distance for calculating the distance gain.

[0102] In some embodiments, for the linear distance attenuation mode, the following formula (or linear distance attenuation formula) may be used to determine the feedback strength lda(d, md, rf) of the haptic signal:

[0103]

[0104] Among them, md is the maximum distance, rf is the attenuation coefficient (roll factor), rd is the reference distance, and d is the distance for calculating the distance gain.

[0105] In some embodiments, for the exponential distance attenuation mode, the following formula (or the exponential distance attenuation formula) can be used to determine the feedback strength eda(d, md, rf) of the tactile signal:

[0106]

[0107] Among them, md is the maximum distance, rf is the attenuation coefficient (roll factor), rd is the reference distance, and d is the distance for calculating the distance gain.

[0108] In some embodiments, the signal attenuation parameter may include one of the following parameters:

[0109] Attenuation coefficient α, the initial tactile feedback strength F obtained from the tactile source max ;

[0110] Among them, the attenuation coefficient is inversely proportional to the square of the distance. Specifically, for example, when the distance R from the tactile source is within the target range (e.g., D min <R≤D max ), the attenuation coefficient is inversely proportional to the square of the distance.

[0111] In some embodiments, the S320 may include:

[0112] Determine the feedback strength of the tactile signal according to the signal attenuation parameter;

[0113] Generate the tactile signal according to the feedback strength of the tactile signal.

[0114] For example, according to the following formula, determine the feedback strength F of the tactile signal:

[0115] F = αF max

[0116] Among them, α is the attenuation coefficient, and F max represents the initial feedback strength obtained from the tactile source;

[0117] Among them, the variation function of α can be expressed as:

[0118]

[0119] Among them, α min is the minimum value of the attenuation coefficient, D min and Dmin Is a predefined value.

[0120] That is, within a certain distance range, such as less than D min it can be considered that the feedback intensity of the tactile signal does not decay, that is, the attenuation coefficient α is set to 1. After exceeding a certain distance range, such as greater than D max , the attenuation coefficient α is set to 0.

[0121] In some embodiments,

[0122] The relationship between the feedback intensity of the tactile signal and the distance obtained from this function is as Figure 4 shown, where the feedback intensity of the tactile signal is a monotonically decreasing interval between the minimum and maximum distances.

[0123] In some embodiments, the custom signal attenuation method can be a signal attenuation method customized by the device manufacturer, that is, not the signal attenuation method specified by the standard.

[0124] In some embodiments, the signal attenuation parameter includes a fixed attenuation amount.

[0125] For example, when using a fixed attenuation amount for attenuation, the target attenuation amount used for signal attenuation can be further indicated. For example, this fixed attenuation amount can be infinite, or it can be 0, or it can be other values. Or, the target attenuation amount used for signal attenuation may not be indicated. In this case, signal attenuation is performed based on the default attenuation amount, and this default attenuation amount can be predefined or set by the user.

[0126] In some embodiments, when using a preset signal attenuation method for attenuation, the signal attenuation parameter includes the parameter used to calculate the attenuation amount of the tactile signal based on the target preset signal attenuation method.

[0127] For example, when using a preset signal attenuation method for attenuation, this signal attenuation parameter can be carried in the first object, such as carried in the tactile source object or the action node object.

[0128] In some embodiments, when using the inverse distance attenuation method, the linear distance attenuation method, or the exponential distance attenuation method, the signal attenuation parameter can include at least one of the following parameters:

[0129] md represents the maximum distance, rf represents the attenuation coefficient (roll factor), rd represents the reference distance, and d represents the distance for calculating the distance gain.

[0130] In some embodiments, when using the inverse square attenuation method, the signal attenuation parameter can include at least one of the following parameters:

[0131] α, representing the attenuation coefficient varying with the distance R, D min , D max .

[0132] Optionally, when there are multiple preset signal attenuation methods, the signal attenuation method indication is used to indicate the target signal attenuation method among the multiple preset signal attenuation methods and the signal attenuation parameters involved in the target signal attenuation method. Both the signal attenuation method indication and the signal attenuation parameters can be carried in the first object, for example, carried in the tactile source object or the action node object.

[0133] In some embodiments, when based on a custom signal attenuation method, the signal attenuation information of the tactile signal may include custom signal attenuation parameters.

[0134] In some embodiments, the enable or disable indication is used to indicate whether to enable the distance-related signal attenuation information when generating the tactile signal (or, whether to enable the signal attenuation parameters and / or the signal attenuation method indication), or rather, to determine whether to consider the signal attenuation caused by the distance factor when generating the tactile signal.

[0135] In some embodiments, when the enable or disable indication is used to indicate enabling the distance-related signal attenuation information, the distance-related signal attenuation information is considered when generating the tactile signal. When disabling the distance-related signal attenuation information, the distance-related signal attenuation information is not considered when generating the tactile signal.

[0136] In some embodiments, the tactile signal type indication is used to indicate the type of the tactile signal to which the distance-related signal attenuation information applies.

[0137] In some embodiments, the signal attenuation caused by the distance factor may be effective only for specific types (such as vibration, heat energy) of tactile signals, or rather, only for specific types of trigger sources, such as vibration, heat energy, etc. Therefore, when describing the signal attenuation information caused by the distance factor, the type of tactile signal to which it applies can be added. In this way, for the tactile signals of this type of tactile signal, this signal attenuation information can be used to generate tactile signals, which is beneficial to ensuring the accuracy of the tactile signal model.

[0138] Embodiment 2: Time-related signal attenuation information

[0139] In some embodiments, the time-related signal attenuation information may be used to characterize the signal attenuation caused by the time factor. For example, the shock or temperature caused by an explosion will decay over time.

[0140] In some embodiments, the time-related signal attenuation information includes at least one of the following:

[0141] A signal attenuation parameter, used to determine the attenuation amount of the haptic signal;

[0142] An indication of the signal attenuation mode of the haptic signal;

[0143] An enable or disable indication, used to indicate whether to enable the time-related signal attenuation information when generating the haptic signal;

[0144] A haptic signal type indication, used to indicate the type of the haptic signal to which the time-related signal attenuation information applies.

[0145] Exemplarily, each piece of information in the time-related signal attenuation information can be carried in at least one of the following objects:

[0146] The haptic source object corresponding to the haptic signal, the avatar object corresponding to the haptic signal, the trigger node object corresponding to the haptic signal, the action node object corresponding to the haptic signal (for example, carried in a child node of the action node object, such as a trigger action media object).

[0147] In some embodiments, the indication of the signal attenuation mode of the haptic signal is used to indicate at least one of the following modes:

[0148] Attenuating by a fixed attenuation amount, attenuating based on a preset signal attenuation mode (for example, based on a preset signal attenuation formula), attenuating based on a custom signal attenuation mode (for example, based on a custom signal attenuation formula).

[0149] In some embodiments, when there are multiple preset signal attenuation modes, the indication of the signal attenuation mode of the haptic signal can further indicate the target preset signal attenuation mode among the multiple preset signal attenuation modes, for example, indicating the target signal attenuation formula among multiple preset signal attenuation formulas.

[0150] In some embodiments, the custom signal attenuation mode can be a signal attenuation mode customized by the device manufacturer, that is, not a signal attenuation mode specified by the standard.

[0151] In some embodiments, the signal attenuation parameter includes a fixed attenuation amount.

[0152] For example, when attenuating by a fixed attenuation amount, it can further indicate the target attenuation amount used for signal attenuation. For example, this fixed attenuation amount can be infinite, or it can be 0, or it can be other values. Or, it can also not indicate the target attenuation amount used for signal attenuation. In this case, signal attenuation is performed based on the default attenuation amount, and this default attenuation amount can be predefined or set by the user.

[0153] In some embodiments, when attenuating using a preset signal attenuation method, the signal attenuation parameter includes a parameter used to calculate the attenuation amount of the haptic signal based on the target preset signal attenuation method.

[0154] For example, when attenuating using a preset signal attenuation method, the signal attenuation parameter can be carried in a first object, such as a haptic source object or an action node object.

[0155] Optionally, when there are multiple preset signal attenuation methods, the signal attenuation method indication is used to indicate the target signal attenuation method among the multiple preset signal attenuation methods and the signal attenuation parameter related to the target signal attenuation method. Both the signal attenuation method indication and the signal attenuation parameter can be carried in the first object, such as a haptic source object or an action node object.

[0156] In some embodiments, when based on a custom signal attenuation method, the signal attenuation information of the haptic signal can include custom signal attenuation parameters.

[0157] In some embodiments, the enable or disable indication is used to indicate whether to enable the time-related signal attenuation information (or, whether to enable the signal attenuation parameter and / or the signal attenuation method indication) when generating the haptic signal, or, whether to consider the signal attenuation caused by time factors when generating the haptic signal.

[0158] In some embodiments, when the enable or disable indication is used to indicate enabling the time-related signal attenuation information, when generating the haptic signal, consider the time-related signal attenuation information. When disabling the time-related signal attenuation information, when generating the haptic signal, do not consider the time-related signal attenuation information.

[0159] In some embodiments, the haptic signal type indication is used to indicate the type of haptic signal to which the time-related signal attenuation information applies.

[0160] In some embodiments, the signal attenuation caused by time factors can be effective only for specific types (such as vibration, heat energy) of haptic signals, or, only for specific types of trigger sources, such as vibration, heat energy, etc. Therefore, when describing the signal attenuation information caused by time factors, the type of haptic signal to which it applies can be added. In this way, for haptic signals of this type of haptic signal, this signal attenuation information can be used to generate haptic signals, which is beneficial to ensuring the accuracy of the haptic signal model.

[0161] Embodiment 3: Signal attenuation information related to an occluder

[0162] In some embodiments, the signal attenuation information related to the occluder can be used to characterize the signal attenuation caused by the occluder. For example, an occluder such as a wall will block the vibration or heat energy brought by an explosion.

[0163] In some embodiments, the signal attenuation information related to the occluder includes at least one of the following:

[0164] A signal attenuation parameter for determining the attenuation amount of the haptic signal;

[0165] An indication of the signal attenuation mode of the haptic signal;

[0166] An enable or disable indication for indicating whether to enable the signal attenuation information related to the occluder when generating the haptic signal;

[0167] A haptic signal type indication for indicating the type of the haptic signal to which the signal attenuation information related to the occluder applies.

[0168] Exemplarily, each piece of information in the signal attenuation information related to the occluder can be carried in at least one of the following objects:

[0169] The haptic source object corresponding to the haptic signal, the avatar object corresponding to the haptic signal, the trigger node object corresponding to the haptic signal, the action node object corresponding to the haptic signal, the occluder object corresponding to the haptic signal (for example, carried in a child node of the action node object, such as a trigger action media object).

[0170] In some embodiments, the indication of the signal attenuation mode of the haptic signal is used to indicate at least one of the following modes:

[0171] Attenuation by a fixed attenuation amount, attenuation based on a preset signal attenuation mode (e.g., based on a preset signal attenuation formula), attenuation based on a custom signal attenuation mode (e.g., based on a custom signal attenuation formula).

[0172] In some embodiments, when there are multiple preset signal attenuation modes, the indication of the signal attenuation mode of the haptic signal can also indicate the target preset signal attenuation mode among the multiple preset signal attenuation modes, for example, indicating the target signal attenuation formula among multiple preset signal attenuation formulas.

[0173] In some embodiments, the custom signal attenuation mode can be a signal attenuation mode customized by the device manufacturer, that is, it is not a signal attenuation mode specified by the standard.

[0174] In some embodiments, the signal attenuation parameter includes a fixed attenuation amount.

[0175] For example, when using a fixed attenuation amount for attenuation, the target attenuation amount used for signal attenuation can be further indicated. For example, the fixed attenuation amount can be infinite, or it can be 0, or it can be other values. Alternatively, the target attenuation amount used for signal attenuation may not be indicated. In this case, signal attenuation is performed based on the default attenuation amount, which can be predefined or set by the user.

[0176] In some embodiments, when using a preset signal attenuation method for attenuation, the signal attenuation parameter includes a parameter used to calculate the attenuation amount of the tactile signal based on the target preset signal attenuation method.

[0177] For example, when using attenuation based on a preset signal attenuation method, the signal attenuation parameter can be carried in a first object, such as a tactile source object or an action node object.

[0178] Optionally, when there are multiple preset signal attenuation methods, the signal attenuation method indication is used to indicate the target signal attenuation method among the multiple preset signal attenuation methods and the signal attenuation parameter involved in the target signal attenuation method. Both the signal attenuation method indication and the signal attenuation parameter can be carried in the first object, such as a tactile source object or an action node object.

[0179] In some embodiments, when based on a custom signal attenuation method, the signal attenuation information of the tactile signal can include custom signal attenuation parameters.

[0180] In some embodiments, the enable or disable indication is used to indicate whether to enable the signal attenuation information related to the occluder (or whether to enable the signal attenuation parameter and / or the signal attenuation method indication) when generating the tactile signal, or in other words, to determine whether to consider the signal attenuation caused by the occluder when generating the tactile signal.

[0181] In some embodiments, when the enable or disable indication is used to indicate enabling the signal attenuation information related to the occluder, the signal attenuation information related to the occluder is considered when generating the tactile signal. When disabling the signal attenuation information related to the occluder, the signal attenuation information related to the occluder is not considered when generating the tactile signal.

[0182] In some embodiments, the tactile signal type indication is used to indicate the type of the tactile signal to which the signal attenuation information related to the occluder applies.

[0183] In some embodiments, the signal attenuation caused by the occluder factor may be effective only for specific types of tactile signals (such as vibration, thermal energy), or rather, only for specific types of trigger sources, such as vibration, thermal energy, etc. Therefore, when describing the signal attenuation information caused by the occluder factor, the type of tactile signal to which it applies can be added. In this way, for the tactile signals of this type of tactile signal, this signal attenuation information can be used to generate tactile signals, which is beneficial to ensuring the accuracy of the tactile signal model.

[0184] In some embodiments, the attribute information of the first object includes an occluder indication, and the occluder indication is used to indicate whether the first object is an occluder. For example, when the first object is an occluder, the tactile signal is generated according to the signal attenuation information related to the occluder. When the first object is not an occluder, the signal attenuation information related to the occluder is not considered when generating the tactile signal.

[0185] Embodiment 4: Signal attenuation information related to body parts

[0186] In some embodiments, the signal attenuation information related to body parts can be used to characterize the signal attenuation caused by the different tactile sensitivities of different body parts. For example, the tactile sensitivities of different body parts of the human body are not the same. For example, the fingertips are highly sensitive, while the back of the hand is less sensitive. Therefore, the tactile signals perceived by different body parts are also different.

[0187] In some embodiments, the signal attenuation information related to body parts includes at least one of the following:

[0188] A signal attenuation parameter for determining the attenuation amount of the tactile signal;

[0193] Exemplarily, each piece of information in the signal attenuation information related to body parts can be carried in at least one of the following objects:

[0194] The haptic source object corresponding to the haptic signal, the avatar object corresponding to the haptic signal, the trigger node object corresponding to the haptic signal, the action node object corresponding to the haptic signal (e.g., carried in a child node of the action node object, such as a trigger action media object).

[0195] In some embodiments, the signal attenuation mode of the haptic signal is used to indicate at least one of the following ways:

[0196] Attenuate by a fixed attenuation amount, attenuate based on a preset signal attenuation mode (e.g., based on a preset signal attenuation formula), attenuate based on a custom signal attenuation mode (e.g., based on a custom signal attenuation formula).

[0197] In some embodiments, when there are multiple preset signal attenuation modes, the signal attenuation mode indication of the haptic signal can also indicate the target preset signal attenuation mode among the multiple preset signal attenuation modes, e.g., indicate the target signal attenuation formula among multiple preset signal attenuation formulas.

[0198] In some embodiments, the custom signal attenuation mode can be a signal attenuation mode customized by the device manufacturer, i.e., not a signal attenuation mode specified by the standard.

[0199] In some embodiments, the signal attenuation parameter includes a fixed attenuation amount.

[0200] For example, when attenuating by a fixed attenuation amount, it can further indicate the target attenuation amount used for signal attenuation. For example, this fixed attenuation amount can be infinite, or it can be 0, or it can be other values. Or, it can also not indicate the target attenuation amount used for signal attenuation. In this case, signal attenuation is performed based on the default attenuation amount, and this default attenuation amount can be predefined or set by the user.

[0201] In some embodiments, when attenuating based on a preset signal attenuation mode, the signal attenuation parameter includes the parameter used to calculate the attenuation amount of the haptic signal based on the target preset signal attenuation mode.

[0202] For example, when attenuating based on a preset signal attenuation mode, this signal attenuation parameter can be carried in the first object, e.g., carried in the haptic source object or the action node object.

[0203] Optionally, when there are multiple preset signal attenuation modes, the signal attenuation mode indication is used to indicate the target signal attenuation mode among the multiple preset signal attenuation modes and the signal attenuation parameter involved in the target signal attenuation mode. Both the signal attenuation mode indication and the signal attenuation parameter can be carried in the first object, e.g., carried in the haptic source object or the action node object.

[0204] In some embodiments, when based on a custom signal attenuation method, the signal attenuation information of the haptic signal may include custom signal attenuation parameters.

[0205] In some embodiments, the enable or disable indication is used to indicate whether to enable the signal attenuation information related to the body part (or, whether to enable the signal attenuation parameter and / or the signal attenuation method indication) when generating the haptic signal, or rather, to determine whether to consider the signal attenuation caused by the body part when generating the haptic signal.

[0206] In some embodiments, when the enable or disable indication is used to indicate enabling the signal attenuation information related to the body part, the signal attenuation information related to the body part is considered when generating the haptic signal. When disabling the signal attenuation information related to the body part, the signal attenuation information related to the body part is not considered when generating the haptic signal.

[0207] In some embodiments, the haptic signal type indication is used to indicate the type of haptic signal to which the signal attenuation information related to the body part applies.

[0208] In some embodiments, the signal attenuation caused by the body part factor may be effective only for a specific type (such as thermal energy) of haptic signal, or rather, only for a specific type of trigger source, such as thermal energy, etc. Therefore, when describing the signal attenuation information caused by the body part factor, the type of haptic signal to which it applies can be added. In this way, for the haptic signal of this haptic signal type, this signal attenuation information can be used to generate the haptic signal, which is beneficial to ensuring the accuracy of the haptic signal model.

[0209] In some embodiments, the body part identifier is used to indicate the body part for which the signal attenuation parameter and / or the signal attenuation method indication are used. Optionally, the signal attenuation information related to the body part may include at least one signal attenuation information related to the body part.

[0210] For example, set the sensitivity value S of each body part of the haptic signal execution object, for example, the value range is [0.0, 1.0], which is used to describe the ratio of the feedback intensity of this body part to sense the haptic signal, and the final perceived feedback intensity F of the haptic signal p = S * F, where F is the original feedback intensity value.

[0211] Embodiment 5: Signal attenuation information related to pressure

[0212] In some embodiments, different signal attenuation or enhancement may be caused by different granularities of contact or pressure, and the pressure-related signal attenuation information can be used to characterize the signal attenuation or enhancement caused by different pressures. For example, the greater the pressing force (the degree of deformation), the stronger the tactile signal.

[0213] In some embodiments, the pressure-related signal attenuation information includes at least one of the following:

[0214] A signal attenuation parameter for determining the attenuation amount of the tactile signal;

[0215] An indication of the signal attenuation mode of the tactile signal;

[0216] An enable or disable indication for indicating whether to enable the pressure-related signal attenuation information when generating the tactile signal;

[0217] A tactile signal type indication for indicating the type of tactile signal to which the pressure-related signal attenuation information applies.

[0218] Exemplarily, each piece of information in the signal attenuation information related to the body part can be carried in at least one of the following objects:

[0219] The tactile source object corresponding to the tactile signal, the avatar object corresponding to the tactile signal, the trigger node object corresponding to the tactile signal, the action node object corresponding to the tactile signal (for example, carried in the child node of the action node object, such as the trigger action media object).

[0220] In some embodiments, the indication of the signal attenuation mode of the tactile signal is used to indicate at least one of the following modes:

[0221] Attenuation by a fixed attenuation amount, attenuation based on a preset signal attenuation mode (e.g., based on a preset signal attenuation formula), attenuation based on a custom signal attenuation mode (e.g., based on a custom signal attenuation formula).

[0222] In some embodiments, when there are multiple preset signal attenuation modes, the indication of the signal attenuation mode of the tactile signal can also indicate the target preset signal attenuation mode among the multiple preset signal attenuation modes, for example, indicating the target signal attenuation formula among multiple preset signal attenuation formulas.

[0223] In some embodiments, the custom signal attenuation mode can be a signal attenuation mode customized by the device manufacturer, that is, not a signal attenuation mode specified by the standard.

[0224] In some embodiments, the signal attenuation parameter includes a fixed attenuation amount.

[0225] For example, when using a fixed attenuation amount for attenuation, the target attenuation amount used for signal attenuation can be further indicated. For example, this fixed attenuation amount can be infinite, or it can be 0, or it can be other values. Alternatively, the target attenuation amount used for signal attenuation can also not be indicated. In this case, signal attenuation is performed based on the default attenuation amount, and this default attenuation amount can be predefined or set by the user.

[0226] In some embodiments, when using a preset signal attenuation method for attenuation, the signal attenuation parameter includes a parameter used to calculate the attenuation amount of the haptic signal based on the target preset signal attenuation method.

[0227] For example, when using attenuation based on a preset signal attenuation method, this signal attenuation parameter can be carried in a first object, such as in a haptic source object or an action node object.

[0228] Optionally, when there are multiple preset signal attenuation methods, the signal attenuation method indication is used to indicate the target signal attenuation method among the multiple preset signal attenuation methods and the signal attenuation parameters involved in the target signal attenuation method. Both the signal attenuation method indication and the signal attenuation parameters can be carried in the first object, such as in a haptic source object or an action node object.

[0229] In some embodiments, when based on a custom signal attenuation method, the signal attenuation information of the haptic signal can include custom signal attenuation parameters.

[0230] In some embodiments, the enable or disable indication is used to indicate whether to enable the pressure-related signal attenuation information (or, whether to enable the signal attenuation parameters and / or the signal attenuation method indication) when generating the haptic signal, or rather, to determine whether to consider signal attenuation caused by pressure when generating the haptic signal.

[0231] In some embodiments, when the enable or disable indication is used to indicate enabling the pressure-related signal attenuation information, when generating the haptic signal, the pressure-related signal attenuation information is considered. When disabling the signal attenuation information related to the body part, when generating the haptic signal, the pressure-related signal attenuation information is not considered.

[0232] In some embodiments, the haptic signal type indication is used to indicate the type of haptic signal to which the pressure-related signal attenuation information applies.

[0233] It should be understood that in the above Embodiments 1-5, the signal attenuation type indications can be the same or different.

[0234] In some embodiments, the signal attenuation parameter is associated with at least one of the following: the type of the haptic signal, the frequency of the haptic signal. For example, the signal attenuation parameter is only effective for a specific type of haptic signal. For another example, the signal attenuation parameter is only effective for haptic signals within a certain frequency range, or haptic signals within different frequency ranges correspond to different signal attenuation parameters.

[0235] For example, the association relationship between the type of the haptic signal and the signal attenuation parameter can also be carried in the first object, for example, carried in the haptic source object or the action node object. For example, it is carried in the first object in the form of a <haptic signal type, signal attenuation parameter> binary tuple.

[0236] For another example, the association relationship between the frequency of the haptic signal and the signal attenuation parameter can also be carried in the first object, for example, carried in the haptic source object or the action node object. For example, it is carried in the first object in the form of a <frequency of the haptic signal, signal attenuation parameter> binary tuple.

[0237] In summary, in the embodiments of the present application, when generating a haptic signal, the signal attenuation information related to at least one of distance, time, occluder, body part, and pressure is considered. Therefore, the haptic signal generated in the embodiments of the present application can more accurately simulate the presentation form of the haptic signal in the real environment, improving the accuracy of the constructed haptic signal model.
