As described in the background, current VR headsets are limited to a single motor that cannot provide different intensity vibration effects, affecting the user's experience.
Aiming at the problems, the application provides VR (virtual reality) head-mounted equipment, which comprises a control module and motor modules which are arranged in an array, wherein at least one first output end of the control module outputs first control signals, at least two second output ends of the control module output different second control signals, the first control signals control at least one row of motor modules to be in an open state, and the different second control signals control at least two motor modules to generate different vibration amplitudes and/or vibration frequencies, so that vibration effects with different intensities can be generated at different positions, and user experience is improved.

Fig. 1 shows a schematic structural diagram of a motor driving chip according to an embodiment of the present application, and fig. 2 shows a schematic structural diagram of a motor matrix according to an embodiment of the present application. As shown in fig. 1 and 2, the VR headset provided in this embodiment includes:
The motor driving chip 10 and the motor matrix 20, wherein the motor driving chip 10 comprises a control module 101 and a plurality of driving modules, the control module 101 comprises a plurality of first output ends and a plurality of second output ends, and the motor matrix 20 comprises a plurality of motor modules 201 which are arranged in an array;
Each first output end of the control module 101 is connected with a control end of a row of motor modules, each second output end of the control module 101 is connected with a driving module, and each driving module is connected with a first end and a second end of a row of motor modules 201;

The at least two second output ends of the control module 101 are configured to output different second control signals to control the at least two driving modules to output different differential signals to control the at least two motor modules 201 to generate different vibration amplitudes and/or vibration frequencies;
The control module 101 is further configured to adjust the intensity of the output second control signal according to the physiological data of the current user, so as to adjust the magnitude of the differential signal output by the corresponding driving module, so as to adjust the vibration amplitude and/or the vibration frequency of the motor module, where the physiological data includes heart rate data and/or blood glucose data.
For example, the control module 101 includes n first output ends and m second output ends, where the n first output ends are respectively denoted as a first output end GATEP, a second first output end GATEP2, a third first output end GATEP3, and so on, until an nth first output end GATEPn; the m second output ends are respectively marked as a first second output end, a second output end, a third second output end and so on until the m second output end.
The first output end GATEP is connected to the control end of the first row of motor modules, the second first output end GATEP is connected to the control end of the second row of motor modules, and so on, the nth first output end GATEPn is connected to the control end of the nth row of motor modules. It will be appreciated that the motor matrix includes n rows of motor modules, and that a first output is connected to the control terminal of each motor module in a row of motor modules.
The first output end of the driving module 1 is connected with the first end of the first row of motor modules, the first output end OUTP1 of the driving module 1 is connected with the second end of the first row of motor modules, and the second output end OUTN1 of the driving module 1 is connected with the first end of the first row of motor modules; the second output end of the driving module 2 is connected with the input end of the driving module 2, the first output end OUTP2 of the driving module 2 is connected with the first end of the second row of motor modules, and the second output end OUTN2 of the driving module 2 is connected with the second end of the second row of motor modules; the third second output end is connected with the input end of the driving module 3, the first output end OUTP3 of the driving module 3 is connected with the first end of the third-row motor module, the second output end OUTN3 of the driving module 3 is connected with the second end of the third-row motor module, and so on, the mth second output end is connected with the input end of the driving module m, the first output end OUTPm of the driving module m is connected with the first end of the mth-row motor module, and the second output end OUTNm of the driving module m is connected with the second end of the mth-row motor module. It is understood that the motor driving chip includes m driving modules, the motor matrix includes m rows of motor modules, a first output end of one driving module is connected to a first end of each motor module in a row of motor modules, and a second output end of one driving module is connected to a second end of each motor module in a row of motor modules.
In the embodiment of the application, a plurality of motor modules are mounted through a single multichannel matrix linear motor driving chip to form a matrix-shaped multi-motor driving system, so that the motor modules at the same position at different times have different vibration frequencies and/or vibration amplitudes, the motor modules at the same time and different positions have different vibration frequencies and/or vibration amplitudes, and the motor modules at different times and different positions have matrix-shaped working modes with different vibration frequencies and/or vibration amplitudes, thereby providing higher-quality immersive vibration feeling experience.
Specifically, the control module may control a portion of the first output terminals to output a first control signal, so as to control a corresponding portion of the driving motor modules to be in an open state, and it needs to be described that only the motor module in the open state may be further in a vibration state. The control module can control part of the second output ends to output second control signals so as to control part of the driving modules to output differential signals, and therefore part of the motor modules in part of the rows are controlled to be in a vibration state. And the control module can control the second output end of the part to output different second control signals so as to control the driving module of the part to output different differential signals, thereby controlling the motor module of the part to generate different vibration amplitudes and/or vibration frequencies.
The second control signals may be driving currents, driving voltages, etc., and the different second control signals may be driving currents with different current values and driving voltages with different voltage values. Accordingly, the different differential signals may be differential signals having different voltage values.
In practical application, the contact part between the inner surface of VR head-wearing equipment and skin is made of skin-friendly material, and the tightness is adjusted by matching with the headband at the rear part of the equipment, so that the effects of tightly fitting the skin surface and preventing light leakage are achieved. Thus, the motor module may be disposed inside the skin-friendly material, or inside the headgear.
In some embodiments, each motor module includes a control switch and a linear motor, wherein for each motor module, the control end of the control switch is used as the control end of the motor module, the first end of the control switch is used as the first end of the motor module, the second end of the control switch is connected with the first end of the linear motor, and the second end of the linear motor is used as the second end of the motor module.
Correspondingly, each first output end of the control module is connected with the control end of the control switch of each motor module in a row of motor modules, which is abbreviated as the control end connected with a row of control switches; the first output end of the driving module is connected with the first end of the control switch of each motor module in a row of motor modules, and the first end is connected with the first end of the control switch, the second output end of the driving module is connected with the second end of the linear motor of each motor module in a row of motor modules, and the second end is connected with the second end of the linear motor. When the control switch receives the first control signal, the control switch is in an open state, and when the control switch is in the open state, the linear motor can be further in a vibration state. And when the second control signals are different, the driving module generates different differential signals, so that different linear motors can generate different vibration amplitudes and/or vibration frequencies at the same time.
In some embodiments, the control module controls the output positions of the first control signal and the second control signal according to the audio position, and controls the intensity of the output second control signal according to the audio intensity, so as to control the magnitude of the differential signal output by the corresponding driving module, so that the vibration area and the vibration intensity of the motor module are consistent with the audio change trend, and the audio change trend comprises audio position change and audio intensity change. In practice, a plurality of speakers, etc. may be included in the VR headset, and the audio location may be determined by the location of the speaker, etc. that produced the audio.
It can be understood that the output position of the first control signal can determine which row or rows of motor modules are in the open state, for example, the output position of the first control signal is the first output end, and then the first row of motor modules are in the open state; for another example, the output positions of the first control signal are the first output end and the second first output end, and the first row of motor modules and the second row of motor modules are in an open state.
Since only the motor module is in the open state, the vibration state can be further entered. Therefore, the output position of the first control signal and the output position of the second control signal can determine which motor module or modules are in vibration state. For example, if the output position of the first control signal is a first output end and the output position of the second control signal is a first second output end, the motor modules in the first row and the first column are in a vibration state; for another example, the output position of the first control signal is a first output end and an nth first output end, N is an integer greater than 1 and less than N, and the output position of the second control signal is a first second output end, so that the motor modules in the first row and the first column and the motor modules in the nth row and the first column are in a vibration state.
In addition, the intensity of the second control signal may determine the vibration amplitude and/or the vibration frequency of the motor module, specifically, the greater the intensity of the second control signal, the greater the intensity of the differential signal output by the driving module, and the greater the vibration amplitude and/or the vibration frequency of the motor module; the smaller the intensity of the second control signal, the smaller the intensity of the differential signal output by the driving module, and the smaller the vibration amplitude and/or the vibration frequency. The second control signal may be, for example, a driving current, a driving voltage, or the like.
Thus, in modes where the user is relatively interested in the immersion experience, e.g., game mode, movie mode, different vibration modes may be set according to the scenario (e.g., different areas of the motor module produce different vibration amplitudes and/or vibration frequencies simultaneously). Specifically, the change of the vibration area of the vibration motor, including the change of the vibration area, the change of the vibration intensity, the vibration amplitude and the like, can be matched according to the change direction of the audiovisual sensory stimulus in the plot, so that the tactile stimulus felt by the head is consistent with the presentation of the audiovisual stimulus.
In some examples, in a movie scene, when the helicopter is low-swept from left to right from the top of the user's head, the acoustic aspect may feel that the propeller noise is gradually shifted from the left channel to the right channel, and the volume is reduced from small to large. Accordingly, if the motor vibration area on the VR headset is made to also coincide with the audio variation trend, the vibration area is gradually shifted from the left side to the right side, and the vibration intensity becomes weak and strong and then weak.
Specifically, the control module controls all the first output ends to output the first control signal in the first period, and controls the first a second output ends to output the second control signal with the first preset intensity so as to control the first a driving modules to output the first differential signal, so as to control the first a motor module to generate the first preset vibration amplitude and/or the first preset vibration frequency, for example, a may be an integer greater than 1 and less than m/2, and m represents the number of columns of the motor module. For example, the front a-column motor module is located on the left side of the VR headset, which refers to the left side of the user from the perspective of the currently wearing user of the VR headset.
The control module controls all the first output ends to output first control signals in a second time period, and controls the first a second output ends to output second control signals with second preset intensity so as to control the first a driving modules to output second differential signals to control the first a motor modules to generate second preset vibration amplitude and/or second preset vibration frequency.
The control module controls all the first output ends to output first control signals in a third time period, and controls the remaining second output ends (the remaining output ends refer to all the second output ends except the first a second output ends) to output third control signals with third preset intensity so as to control the remaining driving modules (the remaining driving modules refer to all the driving modules except the first a driving modules) to output third differential signals so as to control the remaining motor modules (all the motor modules except the first a motor module) to generate third preset vibration amplitude and/or third preset vibration frequency.
Optionally, the first preset intensity may be smaller than the second preset intensity, and the third preset intensity is smaller than the second preset intensity and larger than the first preset intensity, so as to present a vibration experience of the helicopter from left to right in a low-skimming manner, and correspondingly, the third preset vibration amplitude is larger than the first preset vibration amplitude and smaller than the second preset vibration amplitude, and the third preset vibration frequency is larger than the first preset vibration frequency and smaller than the second preset vibration frequency. Optionally, the first preset intensity may be a driving current of a first preset value, the second preset intensity is a driving current of a second preset value, the third preset intensity is a driving current of a third preset value, the first preset value is smaller than the second preset value and smaller than the third preset value, and the second preset value is larger than the third preset value.
In other examples, in a boxing match game scenario, when a user is attacked by a boxing match, the matrix motor vibrates, and the vibration intensity is proportional to the boxing attack intensity, and the vibration area is consistent with the boxing striking position of the visual presentation result. Specifically, the b first output ends output a first control signal to control the b-row motor modules to be in an open state, and the c second output ends output a second control signal to control the c driving modules to output differential signals to control the b×c motor modules to be in a vibration state. The c second control signals can be the same control signals so as to generate the same vibration amplitude and/or vibration frequency in some motor module areas and highlight pain of the boxing hitting position.
The applicant finds that after the VR headset is worn for too long, a pressing sense is generated at the skin contact part of the face, and at this time, if the head is taken off or the head band is loosened for relaxation, the use has to be interrupted, so that the user experience sense is affected.
Therefore, in the embodiment of the application, the control module is further used for adjusting the intensity of the output second control signal according to the physiological data so as to adjust the magnitude of the differential signal output by the corresponding driving module, and further can adjust the vibration amplitude and/or the vibration frequency of the motor module. Wherein the physiological data comprises heart rate data and/or blood glucose data.
As an implementation manner, the control module maintains the intensity of the currently output second control signal when the physiological data is in the first interval; when the physiological data is in the second interval, the intensity of the output second control signal is reduced so as to reduce the differential signal output by the corresponding driving module, reduce the vibration frequency and/or the vibration amplitude of the motor module, and the intensity reduction value of the second control signal can be determined according to the actual situation; when the physiological data is in the third interval, stopping outputting the first control signal to close the vibration of the motor module, or controlling the intensity of the second control signal to be output to fourth preset intensity to convert the mode of the VR headset into the massage vibration mode, wherein the fourth preset intensity can be determined according to the actual situation.
In the massage vibration mode, the vibration area is the position of the head acupoint, such as the acupoint around the forehead, and has a relieving effect. The physiological data of the first interval to the third interval represent the stress and concentration degree of the user, and the stress and concentration degree represented by the first interval to the third interval are sequentially improved. The first interval is the most comfortable interval by default.
In practical application, after the VR headset is worn for a period of time, physiological data of a user are acquired, and an interval in which the physiological data are located is judged. If the physiological data result is located in the first interval, maintaining a vibration mode set in the game or movie plot; if the physiological data result is located in the second interval, reducing the vibration intensity of the vibration mode at the current time set in the game or movie plot; if the physiological data result is located in the third interval, the vibration of the current time set in the game or movie scenario is turned off and/or the massage vibration mode is switched to.
In some examples, a user may establish a personal account on a VR headset, the system defaulting to heart rate data for three intervals, the first interval representing a range of heart rate data in a calm state; the second interval represents a range of heart rate data in a slightly stressed state; the third interval represents the heart rate data range in the stronger intensity state. The system sets a default three interval range according to the statistical heart rate data of children, adults and the elderly (for example, the first interval of the adults is 50-65 times/min, the second interval is 65-80 times/min, and the third interval is 80-120 times/min). The VR head-mounted device can establish a plurality of user accounts, different accounts can have different three interval ranges, and vibration intensities of vibration motors obtained by different users are different in the same scene, and the higher the data endpoint value is, the higher the vibration intensity is. In practical application, the VR headset obtains the user identity when being started, thereby obtaining three corresponding interval ranges.
In some examples, the VR headset includes a sensor configured to acquire physiological data of a current user and send the physiological data to the control module, so that the control module adjusts the magnitude of the differential signal output by the corresponding driving module according to the physiological data of the current user, and may further adjust the vibration amplitude and/or the vibration frequency of the motor module.
Illustratively, the sensor is located within the VR headset, corresponding to the location of the head acupoint, as shown in fig. 3, may be located at either the first location 301 or the second location 302. For example, a sensor is located within the VR headset corresponding to the location of the temple, a temporal artery is located at the temple location, and the sensor can measure heart rate through the temporal artery.
In other examples, the physiological data may be obtained by sensors in communication with the VR headset, e.g., heart rate measurements through the radial artery at the wrist, the instep artery at the ankle, and the carotid artery at the neck, of a wrist-to-ankle, by a watch or wristband, as shown in fig. 4, which may be located at the third location 303 of the wristband. And then the psychological data is transmitted to the VR headset through the wireless connection of the watch or the bracelet and the VR headset.
In some examples, when a user encounters a stimulated scene while playing or viewing a game, the device monitors the user's heart rate data, and when it is detected that the user's heart rate endurance is stronger than a large data range, the upper bound of this user's three-interval may be appropriately expanded. For another example, when it is detected that the heart rate of the user exceeds the upper limit of the third interval under a certain stimulation scenario, the system may remind the user to avoid the discomfort caused by the overstress. Specifically, according to the time that the physiological data is in the first interval, the second interval and/or the third interval, the first interval, the second interval and/or the third interval are adjusted, the adjusted three intervals are used as the interval range of the current user, and when the user wears the VR headset again, the vibration frequency and/or the vibration amplitude are adjusted according to the adjusted three intervals. For example, when the time that the physiological data is in the second interval exceeds the first preset time, the psychological data of the user is indicated to enter the second interval too early, and the range of the second interval can be enlarged so as to reduce the vibration intensity as early as possible; for another example, when the time of the physiological data in the third interval exceeds the second preset time, the range of the third interval may be increased, and the first preset time and the second preset time may be determined according to the actual situation.

And the control module can also adjust the intensity of the output second control signal according to the physiological data of the current user so as to adjust the magnitude of the differential signal output by the corresponding driving module and adjust the vibration amplitude and/or the vibration frequency of the motor module, thereby reducing the uncomfortable feeling of the user and further improving the body feeling of the user while the VR headset is not interrupted.
