Description

Technical Field

[0001] This disclosure relates to the field of smart wearable device technology, and more specifically, to a pupil distance adjustment device, pupil distance adjustment control method, control device and equipment. Background Technology

[0002] In existing VR (Virtual Reality) or MR (Mixed Reality) devices, interpupillary distance (IPD) measurement is typically achieved by using additional sensors, such as Hall effect sensors or variable resistors. Deploying Hall effect sensors requires precise magnetic field simulation, but their linearity is poor and they are easily affected by ambient magnetic fields. Additionally, the introduction of magnets increases the weight of the device. Deploying high-precision variable resistors, to accommodate the large stroke of the IPD, usually results in a relatively large size, posing a significant challenge to miniaturization. Furthermore, high-precision, long-stroke variable resistors are expensive, increasing production costs. Summary of the Invention

[0045] Various exemplary embodiments of this specification will now be described in detail with reference to the accompanying drawings.

[0046] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the embodiments of this specification or their application or use.

[0047] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0048] This disclosure relates to implementation when a user uses or wears an electronic device, which is a VR device or a MR device.

[0049] This disclosure proposes a novel pupil distance adjustment device. By integrating a motor, a first sliding component, a second sliding component, a limiting element, and a laser rangefinder, the device's integration is improved. This significantly reduces the size of the electronic device and facilitates its large-scale application. Furthermore, by determining the current pupil distance value based on the distance measured by the sensor, accurate pupil distance detection can be achieved, reducing system performance issues caused by measurement errors.

[0050] One embodiment of the present invention provides an interpupillary distance adjustment device. According to... Figure 1 As shown, the interpupillary distance adjustment device includes a motor 110, a first sliding component 120, a second sliding component 130, a limiting element 140, a first optical module 150, a second optical module 160, and a laser range sensor 170.

[0051] The first sliding component 120 and the second sliding component 130 are both connected to the lead screw 111 of the motor 110. The first sliding component 120 is fixedly connected to the first optical module 150. The second sliding component 130 is fixedly connected to the second optical module 160. The laser rangefinder sensor 170 is disposed on the first sliding component 120.

[0052] Motor 110 drives lead screw 111 to rotate, thereby causing first sliding component 120 and second sliding component 130 to translate in directions that are closer to or further away from each other, and in turn, causing first optical module 150 and second optical module 160 to translate. The translation speeds of the first sliding component and the second sliding component are equal.

[0053] The limiting element 140 is used to restrict the rotation of the first sliding component 120 and the second sliding component 130 when the lead screw 111 drives the first sliding component 120 and the second sliding component 130 to translate.

[0054] The laser rangefinder 170 is used to measure the distance between the first sliding member 120 and the second sliding member 130 to determine the current interpupillary distance value based on the distance.

[0055] Motor 110 includes a stepper motor and a gearbox. The stepper motor is used to convert electrical energy into mechanical energy. The gearbox is used to reduce the output speed and increase the torque to improve motion accuracy.

[0056] In some embodiments, both the first sliding member 120 and the second sliding member 130 are threadedly connected to the lead screw 111.

[0057] The lead screw 111 has a first threaded section and a second threaded section with opposite directions of rotation. A first sliding member 120 is fitted onto a portion of the first threaded section. A second sliding member 130 is fitted onto a portion of the second threaded section.

[0058] When the lead screw 111 rotates, the first sliding member 120 translates along the first threaded section, and the second sliding member 130 translates along the second threaded section. Since the first threaded section and the second threaded section rotate in opposite directions, the first sliding member 120 and the second sliding member can translate in directions that are closer to each other or further apart from each other.

[0059] The first sliding component 120 and the second sliding component 130 can be rod-shaped components, such as... Figure 1 As shown. One end of the first sliding component 120 and the second sliding component 130 are both threadedly connected to the lead screw 111. The other end of the first sliding component 120 is fixedly connected to the first optical module 150, and the other end of the second sliding component 130 is fixedly connected to the second optical module 160.

[0060] In some embodiments, the limiting element 140 has a slide groove. The ends of the first sliding member 120 and the second sliding member 130 that are not connected to the lead screw both pass through the slide groove, so that the first sliding member 120 and the second sliding member 130 can translate along the slide groove.

[0061] like Figure 1 As shown, the limiting element 140 can be connected to the motor 110. The groove of the limiting element 140 is parallel to the lead screw 111. When the lead screw 111 rotates, the first sliding member 120 and the second sliding member 130 translate along the groove.

[0062] The limiting element 140 has a groove, which can limit the first sliding component 120 and the second sliding component 130 to only retain a single degree of translational freedom and eliminate the rotational degree of freedom.

[0063] When the first sliding component 120 translates, it drives the first optical module 150 to translate in the same direction. When the second sliding component 130 translates, it drives the second optical module 160 to translate in the same direction. This causes the first optical module 150 and the second optical module 160 to translate in directions that bring them closer together or further apart, thereby adjusting the interpupillary distance to decrease or increase.

[0064] like Figure 1 As shown, the first sliding component 120 has a groove, and the laser rangefinder 170 is disposed in the groove.

[0065] The transmitter in the laser rangefinder emits a laser beam toward the second sliding member 130, and the detector in the laser rangefinder receives the laser beam reflected back from the second sliding member 130. Based on the laser's propagation speed and propagation time, the laser rangefinder calculates the distance between the first sliding member 120 and the second sliding member 130.

[0066] The laser rangefinder is used to emit a laser beam from a transmitter to a second sliding member and to receive the laser beam reflected from the second sliding member by a detector; to determine the time of flight of the laser beam, wherein the time of flight of the laser beam is the time interval between emitting the laser beam and receiving the reflected laser beam; and to determine the distance between the first sliding member and the second sliding member based on the time of flight of the laser beam and the speed of flight of the laser beam.

[0067] The distance between the first sliding component and the second sliding component is determined based on the following calculation formula.

[0068]

[0069] Where d is the distance between the first sliding component and the second sliding component, c is the flight speed of the laser, and Δt is the flight time of the laser.

[0070] It should be noted that the laser rangefinder 170 can also be mounted on the second sliding component 130.

[0071] One embodiment of the present invention provides a pupillary distance adjustment control method. This pupillary distance adjustment control method is applied to the pupillary distance adjustment device provided in any of the above embodiments. Figure 2 As shown, the pupil distance adjustment and control method of this embodiment may include the following steps S210 to S230.

[0072] In step S210, in response to the first interpupillary distance adjustment component being triggered, the motor is controlled to drive the lead screw to rotate, thereby causing the first sliding component and the second sliding component to translate.

[0073] The first interpupillary distance adjustment component can be a button. When the user triggers the button, the above step S210 is executed.

[0074] When the motor drives the lead screw to rotate, it drives the first sliding component and the second sliding component to translate in a direction that moves closer to or further away from each other, thereby driving the first optical module and the second optical module to translate in a direction that moves closer to or further away from each other.

[0075] Step S220: Obtain the first distance value measured by the laser rangefinder. The first distance value is the real-time distance between the first sliding component and the second sliding component.

[0076] The laser rangefinder can perform a measurement at preset intervals to obtain a first distance value, and then report the first distance value to the pupil distance adjustment device.

[0077] Step S230: Determine the current interpupillary distance value based on the first distance value measured by the laser rangefinder.

[0078] In this embodiment, the current interpupillary distance is determined by measuring the first distance value using a laser rangefinder. Because the laser rangefinder has high measurement accuracy, it can accurately measure the current interpupillary distance.

[0079] In some embodiments, step S230 specifically includes steps S231 to S233.

[0080] Step S231: Obtain the second distance value and the interpupillary distance value corresponding to the second distance value, wherein the second distance value is the distance between the first sliding component and the second sliding component when the first sliding component is located at the first set position and the second sliding component is located at the second set position.

[0081] The second distance value and the corresponding pupillary distance value are both pre-calibrated values ​​stored in the pupillary distance adjustment device and can be directly obtained.

[0082] When the first sliding component is in the first set position and the second sliding component is in the second set position, the interpupillary distance is at its maximum value; or, when the first sliding component is in the first set position and the second sliding component is in the second set position, the interpupillary distance is at its minimum value.

[0083] Step S232: Determine the distance change value between the first sliding component and the second sliding component based on the first distance value and the second distance value.

[0084] When the first sliding component translates, it causes the first optical module to translate in the same direction and by the same distance. When the second sliding component translates, it causes the second optical module to translate in the same direction and by the same distance. Therefore, the change in distance between the first and second sliding components is equal to the change in interpupillary distance.

[0085] Step S233: Determine the current interpupillary distance value based on the interpupillary distance value corresponding to the second distance value and the distance change value between the first sliding component and the second sliding component.

[0086] The change in distance between the first sliding component and the second sliding component is equal to the change in interpupillary distance. Based on the interpupillary distance value corresponding to the second distance value and the change in interpupillary distance, the current interpupillary distance value is determined.

[0087] In some embodiments, the method further includes: in response to the second interpupillary distance adjustment component being triggered, controlling the motor to stop driving the lead screw to rotate; acquiring the current user's identification information and the determined current interpupillary distance value; and storing the current user's identification information and the determined current interpupillary distance value in the association relationship between user identification information and interpupillary distance value.

[0088] The second interpupillary distance adjustment component can be a button. The first and second interpupillary distance adjustment components can be the same button or two different buttons.

[0089] When the user triggers the first interpupillary distance (IPD) adjustment component, the IPD measuring device controls the motor to rotate the lead screw, causing the first and second sliding components to initially move closer together, which in turn moves the first and second optical modules closer together, thus decreasing the IPD value. When the IPD value reaches the set minimum value, the IPD measuring device controls the motor to rotate the lead screw in the opposite direction, causing the first and second sliding components to initially move further apart, which in turn moves the first and second optical modules further apart, thus increasing the IPD value. When the IPD value reaches the set maximum value, the IPD measuring device controls the motor to rotate the lead screw in the opposite direction, causing the first and second sliding components to initially move closer together, and so on, until the user triggers the second IPD adjustment component, stopping the motor from rotating the lead screw. It should be noted that the motor can also initially move the first and second sliding components further apart, and then, when the IPD value reaches the set maximum value, move them closer together.

[0090] A user's identification information represents the user's identity information and is unique.

[0091] The user's identification information can be the account information of the corresponding application that the user logs into when using an electronic device. This electronic device can be a VR device or a MR device. The corresponding application logged into when using the electronic device is an application installed on other terminal devices.

[0092] The user's identification information can also be their biometric information, such as facial images, iris scans, or fingerprints. Facial images can be captured by the electronic device's built-in camera. Iris scans can also be captured by the electronic device's built-in camera. Fingerprints can be detected by the electronic device's built-in fingerprint sensor. This electronic device can be a VR or MR device.

[0093] The association between user identification information and interpupillary distance (IPD) values ​​stores the appropriate IPD values ​​for different users. This allows the system to automatically retrieve the appropriate IPD value for a user when that user uses the electronic device.

[0094] In some embodiments, the method further includes: obtaining the current user's identification information; determining an interpupillary distance value suitable for the current user based on the correlation between the current user's identification information, user identification information, and interpupillary distance value; and controlling a motor to drive a lead screw to rotate based on the interpupillary distance value suitable for the current user, so as to drive the first sliding component and the second sliding component to translate, thereby driving the first optical module and the second optical module to translate, until the current interpupillary distance value reaches the interpupillary distance value suitable for the current user.

[0095] The current user is someone who is using or wearing an electronic device.

[0096] In this embodiment, when a user uses the electronic device, the corresponding adaptive interpupillary distance value can be automatically obtained from the association between the user identification information and the interpupillary distance value, and the motor can be controlled to perform subsequent interpupillary distance adjustment and measurement operations so that the interpupillary distance value can be adapted to the current user's interpupillary distance value, thereby improving the user experience.

[0097] This disclosure also provides a pupillary distance adjustment control device for implementing any of the above method embodiments. The pupillary distance adjustment control device is used to control the pupillary distance adjustment device provided in any of the above embodiments.

[0098] Figure 3 A structural block diagram of an interpupillary distance adjustment control device according to some embodiments is shown. For example... Figure 3 As shown, the pupil distance adjustment and control device may include a control module 310, a distance value acquisition module 320, and a pupil distance value determination module 330.

[0099] The control module 310 is used to control the motor to drive the lead screw to rotate in response to the first interpupillary distance adjustment component being triggered, so as to drive the first sliding component and the second sliding component to translate.

[0100] The distance value acquisition module 320 is used to acquire the first distance value measured by the laser rangefinder. The first distance value is the real-time distance between the first sliding component and the second sliding component.

[0101] The interpupillary distance determination module 330 is used to determine the current interpupillary distance value based on the first distance value measured by the laser rangefinder.

[0102] In some embodiments, the interpupillary distance determination module 330 is used to obtain a second distance value and an interpupillary distance value corresponding to the second distance value, wherein the second distance value is the distance between the first sliding component and the second sliding component when the first sliding component is located at a first set position and the second sliding component is located at a second set position; determine the distance change value between the first sliding component and the second sliding component based on the first distance value and the second distance value; and determine the current interpupillary distance value based on the interpupillary distance value corresponding to the second distance value and the distance change value between the first sliding component and the second sliding component.

[0103] In some embodiments, the control module is further configured to control the motor to stop rotating the lead screw in response to the triggering of the second interpupillary distance adjustment component.

[0104] In this embodiment, the device further includes a storage module. The storage module is used to obtain the current user's identification information and the determined current interpupillary distance value; and to store the current user's identification information and the determined current interpupillary distance value in the association relationship between user identification information and interpupillary distance value.

[0105] In some embodiments, the device further includes a user identifier acquisition module and an interpupillary distance value determination module adapted to the user.

[0106] The user identification acquisition module is used to acquire the identification information of the current user. The interpupillary distance (IPD) value determination module is used to determine the IPD value suitable for the current user based on the current user's identification information, the correlation between the user identification information and the IPD value. The control module is also used to control the motor to drive the lead screw to rotate based on the IPD value suitable for the current user, so as to drive the first sliding component and the second sliding component to translate, and then drive the first optical module and the second optical module to translate, until the current IPD value reaches the IPD value suitable for the current user.
