Virtual reality (virtual reality) technology is a collection of technologies such as simulation technology, computer graphics human-computer interface technology, multimedia technology, sensing technology, and network technology. In a virtual reality technology-based system, a user can see and touch a virtual object. In order to simulate the feeling of the hand actually touching the virtual object, the common device of the virtual reality technology is to install some touch points which can vibrate on the inner layer of the glove or simulate the touch feeling by the vibration transmitted from the hand-held sensing handle. However, the disadvantages of the above approach are also evident. For example, the vibrating contacts in the handle and glove can only simulate the touch of a small percentage of real objects, and the glove also isolates the hand from the air, which is not comfortable.
The following describes in detail a specific implementation of a haptic feedback device and method provided by the embodiments of the present disclosure with reference to fig. 1-4.
As shown in fig. 1, embodiments of the present disclosure provide a haptic feedback device 100 that may be used in virtual reality technology. The haptic feedback device 100 includes: at least one connection structure 160 (e.g., 160a, 160b, 160c, etc. in fig. 1), a wearable device 101, and at least one signal generator 180 (e.g., 180a, 180b, 180c, etc. in fig. 1). One end of the connection structure 160 is connected to the wearable device 101, and the other end of the connection structure 160 is connected to the signal generator 180. The connection structure 160 represented by arrows in fig. 1 is only used to illustrate that the wearable device 101 and the signal generator 180 can be connected through two ends of the connection structure 160, and the following embodiments can be referred to for the specific structure of the connection structure 160.
The wearable device 101 described above may be configured to perform the following operations: detecting a target position; determining a virtual object at the target location; generating a control signal according to the virtual object; and sending the control signal to the signal generator.
The signal generator 180 may be configured to generate a sensing signal according to a control signal generated by the wearable device 101 and output the sensing signal. Further, the sensing signal will be sensed by the hand of the person who emits the sensing action (e.g., touch action).
In some embodiments, the control signal may be transmitted in a wired manner. Accordingly, the connection structure 160 may include: the circuit board comprises a shell and a signal wire positioned inside the shell. The signal line is configured to transmit the control signal from the wearable device 101 to the signal generator 180. For example, the signal line is one or more transmission lines formed by a plurality of cable lines, and the carrier of the signal line can be metal or other carriers, such as an optical cable and the like.
In some embodiments, the housing is made of a deformable and bendable material. For example, the deformable and bendable material may include metal such as iron, copper or aluminum. For example, signal lines using a metal carrier constitute a plurality of transmission lines, which may be distributed inside a metal case.
In some embodiments, the control signal is transmitted wirelessly, and specifically, a short-range wireless transmission technology may be used. The corresponding attachment structure 160 may be a deformable elongated rod. The deformable long rod is also made of deformable and bendable materials. Specifically, the deformable and bendable material includes metals such as iron, copper or aluminum. For example, an iron rod is used as the connection structure 160, one end of the iron rod connection structure 160 is connected to the wearable device 101, and the other end is connected to a signal generator 180. For example, the short-range wireless transmission technology includes bluetooth, ultra wideband, wifi, or the like. For example, the wearable device 101 may include a first wireless transceiver and the signal generator 180 includes a second wireless transceiver through which the wearable device 101 and the signal reproducer 180 may communicate.
In some embodiments, the haptic feedback device 100 may simultaneously transmit the generated control signal in one of a wired manner or a wireless manner. At this time, the corresponding connection structure 160 is implemented by using the housing and the signal line disposed inside the housing. For the purpose of simultaneously transmitting the control signal wirelessly, the wearable device 101 may include a first wireless transceiver and the signal generator 180 includes a second wireless transceiver. The generated control signals may be transmitted wirelessly when the haptic feedback device 100 is operating in an environment covered by a wireless network. When the haptic feedback device 100 operates in an environment without network coverage or when the network coverage signal is poor, the generated control signal may be transmitted in a wired manner, i.e., through a signal line inside the connection structure 160.
In some embodiments, the haptic feedback device 100 includes a plurality of connection structures 160 and a plurality of signal generators 180, with a one-to-one correspondence between the connection structures 160 and the signal generators 180. That is, one connection structure 160 is connected to one signal generator 180, wherein a plurality of signal generators 180 may belong to different categories, respectively generating and outputting different sensing signals.
The connection structures 160 are dispersedly disposed on the wearable device 101. For example, when the wearable device 101 is a bracelet, the connection structure 160 is dispersedly connected to the bracelet.
In order to make the parts of the hand respectively sense the feeling of touching the virtual object, the lengths of the connecting structures 160 may not be equal in some embodiments. For example, a shorter connecting structure 160 is provided corresponding to the palm position, while a relatively longer connecting structure 160 is provided for the fingertip portion. In other embodiments, the connecting structures 160 may be bent to achieve the purpose of making different parts of the hand feel the tactile signals, and the lengths of the connecting structures 160 may be equal or similar.
In some embodiments, a different number and a different type of multiple signal generators may be used in order to achieve a perception effect that simulates different virtual objects. That is, the perception of various virtual objects is simulated to the person by adjusting the number and kinds of the signal generators 180. For example, when the touched virtual object is a virtual object with low heat, two heat signal generators can be used for generating heat; if the virtual object to be touched is a hot virtual object, five or even six heat signal generators may be used to generate heat simultaneously.
In some embodiments, wearable device 101 may include sensor 108. The sensor 108 may be configured to detect the target position. The target location is where the virtual object the user is attempting to perceive (e.g., touch) is located. The target position may be characterized using position information, for example, using two-dimensional coordinates or three-dimensional coordinates as position information. For example, the sensor 108 may be a position sensor. In some examples, the sensor 108 may determine the target location from a trajectory of the user's hand movements. For example, the position pointed by the user's hand is the target position.
In some embodiments, wearable device 101 may further include: a memory 103, and a processor 102. The memory 103 may be configured to store position information of a plurality of virtual objects, and the processor 102 may be configured to identify a virtual object at the target position from the position information of the plurality of virtual objects stored by the memory 103. Specifically, the memory 103 stores virtual objects corresponding to the positions, and after the processor 102 reads the target position, the virtual object at the target position can be found by using a matching strategy. For example, the memory 103 stores that the virtual object at the spatial position (1,1,1) is an ice block, and when the user touches the spatial position (1,1,1), the processor 103 determines that the virtual object touched by the user at this time is an ice block.
In some embodiments, identification information may also be set on the virtual object, and the processor 102 may then identify the virtual object by determining the identification information. For example, all virtual objects are uniformly coded, each virtual object corresponds to a unique coded identifier, and each virtual object is represented by one piece of identifier information. Accordingly, the memory 103 may store a mapping table of the correspondence of the identification information with the virtual object. Specifically, when the user touches the virtual object at the target position, the virtual object at the target position may be obtained by reading the identification information stored on the virtual object at the target position, and then by analyzing the identification information by the processor 102. For example, the encoded identification information may be stored using a two-dimensional code or the like.
The types of the virtual objects may include all objects in the real world, such as objects with different temperatures or conductive objects, which may be sensed by the touch of the user. For example, an alarm signal may also be issued when a dangerous virtual object is touched.
In some embodiments, the memory 103 may be further configured to store attribute information of the plurality of virtual objects; the processor 102 is further configured to: acquiring attribute information of the virtual object at the target position according to the attribute information of the virtual objects; and generating, by the processor 102, a corresponding control signal in accordance with the attribute information of the virtual object at the target position.
For example, the attribute information is information that can represent a perceptual feature of the virtual object, for example, information that represents a tactile feature of the virtual object. For example, when the virtual object is an ice block, the corresponding attribute information may be a cool; when the virtual object is a jade bracelet, the corresponding attribute information may be smooth, etc.
Further, in some instances, the haptic feedback device 100 may also include a processing device (not shown in the figures). Only the location-aware sensor 108 may be provided on the wearable device 101, and all or part of the functions of the memory 103 and the processor 102 described above may be implemented in the processing device. Accordingly, a transmitter needs to be arranged on the wearable device 101 to transmit the target location to the processing device, the processing device identifies the virtual object at the target location, and further the processing device obtains the attribute information of the virtual object and finally generates a control signal, and the control signal is generated to the signal generator 180. For example, the processing device may send the control signal to the signal generator 180 through a wireless channel, or the processing device may send the control signal to the wearable device 101 before the wearable device 101 sends the control signal to the signal generator 180 in a wired or wireless manner.
In some embodiments, the signal generator 180 may be spherical or funnel shaped in shape. When the spherical signal generator is adopted, the spherical generator outputs sensing signals to all directions of the space, so that the placement position of the palm or the fingers is flexible. When a funnel-shaped or other shaped signal generator is used, it is necessary to analyze the position of the finger or palm relative to the signal generator in order to make the sensing signal output by the signal generator perceivable by the palm or finger. The sensing signal is generated by the signal generator 180 according to the control signal.
In some embodiments, the signal generator 180 may include multiple categories, wherein each category of signal generator may generate a single or composite sense signal. For example, the kind of signal generator may specifically include one or more of a light signal generator, an electrical signal generator, a wind signal generator, a vibrator, and a cold and hot signal generator.
For example, an electric signal generator generates an electric current through two electrodes to cause a person to feel a slight shock or a tingle, a wind signal generator generates an air current through a micro fan that heats and cools to be ejected from a tip, and the like.
In some embodiments, the wearable device 101 may include a bracelet, a wearable wristband, a wearable armband, a wearable ring, or the like.
Fig. 2 and 3 will further describe an embodiment of the present disclosure by taking a smart bracelet as an example.
The intelligent bracelet that following technical scheme relates to can be complete bracelet or jagged bracelet, only need to guarantee to jagged bracelet can be worn on the wrist by the user can.
As shown in fig. 2, the present disclosure provides a haptic feedback device that employs a smart bracelet 201 as a wearable device 101 and a ball generator 280 as a signal generator 180. The connection structure 260 may be a housing and a structure in which signal lines are provided in the housing, or may be a long bar that is used only to support and fix the respective signal generators. When a long rod is used as the connection structure, the smart band 20 needs to use a wireless transceiver to send a control signal to the signal generator 280, or use the wireless transceiver to send or receive a signal related to the smart band 201. For example, the signal related to the smart band 201 includes, but is not limited to, a target location signal. The length of each connection structure 260 is unequal.
As shown in fig. 3, an embodiment of the present disclosure provides a schematic diagram of touching a spatial virtual object using the haptic sensing apparatus 200 of fig. 2. The user wears the haptic sensing device 310 (corresponding to the haptic feedback device 200 of fig. 2) and touches a position a of the space where a pentagonal heat generating unit 320 is placed.
The operation of the haptic feedback device 310 described above is as follows: when a user wears the haptic feedback device 310 and touches a point a in the space where the heating element 320 is placed, the smart bracelet of the haptic feedback device 310 reads the coordinate information of the target position a, and then determines that the virtual object at the target position is a pentagonal heating element 320 according to the coordinate information. The intelligent bracelet regenerates control information according to the attribute information of the heating body, and then controls the corresponding spherical signal generator to generate a heat radiation signal, so that a user can perceive the heat radiation signal of the heat signal generator.
The haptic feedback device 310 integrates a position sensing function, a virtual object recognition function, and a control signal generation function. To achieve these functions, a processor, a memory, and a sensor are required to be disposed on the smart bracelet of the haptic feedback device 310. The processor reads the instruction code from the memory, reads the position sensing data from the sensor, reads the related data (for example, the related data may include a correspondence table of the position information and the virtual object or a correspondence table of the virtual object and the attribute information) stored in the memory in advance, and performs a corresponding function according to the read data and finally outputs a control signal. The haptic feedback device 310 may output the generated control signal to the signal generator in a wired or wireless manner. Each signal generator generates a sensing signal in response to a corresponding control signal and outputs the sensing signal to the periphery of each signal generator.
In some embodiments, the smart band included in the haptic feedback device 310 may be used only for implementing the location awareness function, and both the identification function and the attribute information acquisition function for the virtual object are implemented by the processing device. The smart band transmits the sensed location information (i.e., the target location) to the processing device, and the processing device performs part or all of the functions of virtual object recognition or attribute information acquisition. And then, the intelligent bracelet can send control signals to each signal generator in a wired and wireless mode. Each signal generator generates a sensing signal in response to a corresponding control signal and outputs the sensing signal to the periphery of each signal generator.
In some embodiments, the smart band is further provided with a detection unit (not shown in the figure) capable of detecting the target position in real time or periodically. If the detection unit finds that the target position is changed, the processor 102 may be informed to acquire the virtual object according to the new target position and finally generate the control signal. Accordingly, after the target position changes, the processor 102 may generate an instruction to turn off the currently turned on signal generator.
As shown in fig. 4, embodiments of the present disclosure also provide a haptic feedback method 400. The haptic feedback method 400 may include: step 401, detecting a target position; step 411, determining a virtual object at the target position; step 421, generating a control signal according to the virtual object; and step 431, generating a sensing signal according to the control signal and outputting the sensing signal.
In some embodiments, the detection target position may be derived from a touch position of the hand sensed by the sensor. Specifically, the center position of the palm or the fingertip position of the hand may be set as the target position, or it may be further determined whether the center position of the palm or the fingertip position is set as the target position in combination with the characteristics of the virtual object. For example, the palm center position may be adopted as the target position for a virtual object that needs to be grasped by the palm (virtual object such as egg), and the finger tip position may be adopted as the target position for a virtual object that needs to be touched by the finger tip (some button keys). In addition, the pointing position of the hand can be used as the target position, and the corresponding sensor needs to read the pointing information of the corresponding finger.
In some embodiments, the virtual object at the target position may be obtained by determining the virtual object at the target position using a table of correspondence between the target position and the virtual object. For example, a correspondence table between each position and the virtual object is stored in advance, the target position of the current finger is acquired, and the virtual object located at the target position is obtained by searching the correspondence table. The target location may be characterized in two-dimensional or three-dimensional coordinates. The touch target position can also be represented by character strings such as labels, and the like, wherein all position points for placing virtual positions need to be uniformly coded, one virtual object corresponds to one code, and the code is adopted to represent the touch target position. The corresponding relationship table needs to store the corresponding relationship between the codes and the virtual objects.
In some embodiments, generating the control signal according to the virtual object may specifically be generating a corresponding control signal through attribute information of the virtual object. Or directly generating corresponding control signals according to the virtual objects, namely generating corresponding control signals by analyzing the perception effect of the virtual objects in advance, and directly reading the corresponding control signals after judging the virtual objects.
The control signal may be an on signal or an off signal for activating the corresponding signal generator, or may be a signal for changing the signal strength of the corresponding signal generator. The information carried by the specific control signal can be adjusted in real time according to the actual characteristics of the touched virtual object.
For example, the determining the virtual object at the target position in step 411 may specifically include: acquiring stored position information of a plurality of virtual objects; and identifying the virtual object at the target position according to the position information of the virtual objects. In some embodiments, the corresponding position of the virtual object may be a coordinate range, or may be a coordinate at the center of the virtual object. When one coordinate range is adopted to correspond to the virtual object, if the target position falls in the coordinate range of a certain virtual object B, the touched virtual object is known as B; or if the target position falls within a certain range close to the outer edge of a certain virtual object C (the size of the range is adjusted by setting a threshold), the virtual object touched at this time is known as C. When the position information of each virtual object is represented by a coordinate value, if the target position is the same as the coordinate value of a certain virtual object D, the virtual object at the target position is D; if the absolute value of the difference between the target position and the coordinate value of a certain virtual object E is sufficiently small (for example, the difference is smaller than a predetermined threshold), the virtual object at the target position is E.
For example, the step 421 of generating the control signal according to the virtual object may include: acquiring stored attribute information of the plurality of virtual objects; acquiring attribute information of the virtual object at the target position according to the attribute information of the virtual objects; and generating the control signal according to the attribute information of the virtual object at the target position. For example, the attribute information category may include, cool, hot, smooth, rough, vibrating, and the like. For example, the control signal generated according to the attribute information may be a signal generator that is determined to be turned on according to the attribute information, and feature information such as intensity or frequency of a sensing signal generated by the signal generator is determined according to the attribute information, and then the turn-on signal and the feature information are encapsulated according to a communication protocol to generate a final control signal.
