Description

Technical Field

[0001] This invention relates to the field of head-mounted display technology, and particularly to a handle for a head-mounted display device. Background Technology

[0002] With the continuous advancement of virtual reality (VR), augmented reality (AR), and mixed reality (XR) technologies, head-mounted display devices are gaining popularity among young people due to their rich experiential offerings. Virtual reality technology is a computer simulation system that creates and allows users to experience virtual worlds. It utilizes computers to generate a simulated environment, a multi-source information fusion interactive three-dimensional dynamic visual and physical behavior system simulation that immerses the user in that environment. People experience the virtual reality world by wearing head-mounted display devices. With the development of electronic technology, head-mounted display devices will gradually become more widespread in people's daily lives.

[0003] Typically, in scenarios where users engage with virtual reality devices, they can interact with the head-mounted display via controllers. Specifically, if a user needs to trigger the head-mounted display to perform a certain operation, the user can first initiate a connection between the head-mounted display and the controller, and then move the controller as input. This allows the head-mounted display to obtain the relative position information of the controller based on the infrared light emitted by the controller's LED light source, and then perform the operation based on that position information.

[0004] In related technologies, during the use of head-mounted display devices, to achieve controller positioning in virtual scenes, mainstream controller positioning and tracking technologies involve arranging an infrared light array on the controller, which is then captured and positioned by the head-mounted display device's camera. To ensure the stable implementation of this solution, some related technologies require designing a protruding light ring on the controller, with a ring-shaped array of infrared lights arranged on it, ensuring that the infrared lights can be captured in most scenarios. Other related technologies place the infrared lights on a single plane or curved surface. Summary of the Invention

[0079] In related technologies, during the use of head-mounted display devices, to achieve controller positioning in virtual scenes, mainstream controller positioning and tracking technology involves arranging an array of infrared lights on the controller, which is then captured and positioned by the camera of the head-mounted display device. To ensure the stable implementation of this solution, a ring-shaped array of infrared lights needs to be designed on the controller to ensure that the infrared lights can be captured in most scenarios. This design results in the infrared lights on the controller being relatively close together, or the infrared lights being on the same plane or curved surface, causing the light from each infrared light to interfere with each other, affecting the identification of the infrared light positions. This application provides a controller for head-mounted display devices to solve the above-mentioned technical problems.

[0080] Virtual reality technology

[0081] Virtual Reality (VR) is a novel and practical technology that emerged in the 20th century. It encompasses computer science, electronic information, and simulation technology. Its basic implementation involves using computers to simulate a virtual environment, creating a sense of immersion. VR refers to creating a virtual space through external devices; people can then enjoy applications such as watching movies and playing games within this virtual space. Typically, a head-mounted display device is a pair of glasses equipped with multiple cameras.

[0082] A head-mounted display (HMD) may include a head-mounted display (i.e., the main unit) and handles. One or two handles may be used. The head-mounted display is worn on the user's head and includes a display device, a processor, and multiple cameras, primarily used for two applications: environmental see-through detection and degree of freedom (DoF) detection.

[0083] In some implementations, head-mounted displays also employ camera configurations that separate see-through and DoF detection functions (i.e., see-through typically detects visible light signals, while DoF detects both visible and infrared signals). In this case, an additional dedicated see-through camera is usually required. The infrared signal is primarily used for controller position detection. Head-mounted display DoF recognition typically establishes a wireless connection with the controller, which is equipped with a specific infrared light source (e.g., 850nm infrared band) to facilitate the camera on the head-mounted display capturing the controller's pose information.

[0084] For ease of description and understanding, the user's grip on the handle is used as a reference.

[0085] Figure 1 This is a schematic diagram of the handle of the present invention. Figure 2 This is an exploded view of the handle of the present invention. Figure 3 This is a partial schematic diagram of the handle of the present invention.

[0086] See Figures 1 to 3 This embodiment provides a handle for a head-mounted display device. The main body of the head-mounted display device obtains the position and position changes on the handle, determines the position and posture of the handle, and thus generates corresponding information and instructions in the head-mounted display device to realize the interaction between the head-mounted display device and the user.

[0087] The handle includes a grip portion 110 and an operating portion 120 formed at one end of the grip portion 110 in the longitudinal direction. The grip portion is for being held by the hand in the longitudinal direction. The grip portion 110 is arranged circumferentially for the user's fingers other than the thumb and the palm to hold.

[0088] In some embodiments, the handle may include a housing 100, within which a receiving space is formed for accommodating structures such as electronic components. A grip portion and an operating portion are respectively formed on the housing.

[0089] In some embodiments, the handle includes an operating portion 110 and a grip portion 120, with the operating portion formed at one end of the grip portion.

[0090] In some embodiments, the operating part 120 is fixed to one end of the gripping part 110 in the length direction.

[0091] In some embodiments, the gripping part 110 and the operating part 120 can be integrally formed, partially integrally formed, or separately formed and then spliced ​​together, etc., as long as the operating part 120 is located at one end of the gripping part 110.

[0092] Figure 4This is a schematic diagram of the structure of the operating part of the present invention. Figure 5 This is a schematic diagram of the positioner of the present invention on the operating part. Figure 6 This is a schematic diagram of a user using the handle according to the present invention.

[0093] See Figures 1 to 6 The operating part 120 has an operating surface on the side facing away from the grip part 110. The operating surface intersects the handle at an angle along its length for use by the user's thumb for pressing and operation.

[0094] The operating surface includes a first region 121 and a second region 122 spaced apart; the edges of the first region 121 and the second region 122 both extend along the edge of the operating surface.

[0095] In some embodiments, the first region 121 and the second region 122 are each provided as half. In this embodiment, the first region 121 and the second region 122 are respectively configured as fan-shaped structures.

[0096] In some embodiments, the first region 121 is a region for setting buttons, and the second region 122 is a region for setting locators.

[0097] In some embodiments, the first region 121 is closer to the base of the thumb when holding the handle than the second region 122. When holding the handle, the distance between the second region and the base of the thumb is greater than the distance between the first region and the base of the thumb.

[0098] In this embodiment, a first through-hole 123 is provided in the first region 121, and multiple first through-holes 123 are provided in the first region 121. A second through-hole 124 is provided in the second region 122, and multiple second through-holes 124 are provided in the second region 122. The second through-holes 124 can be blind holes.

[0099] In some embodiments, the first region 121 and the second region 122 are located on a plane or a curved surface.

[0100] In some embodiments, the first region 121 and the second region 122 are located on two intersecting surfaces to form different angles with respect to the length direction of the handle. For example, the first region 121 for setting the button has a smaller angle with the length direction than the second region 122 for setting the locator, so that while facilitating thumb pressing, the signal emission direction of the locator does not need to be excessively tilted towards the length direction, and thus the emitted signal is less likely to be blocked by the arm or body during operation.

[0101] In some embodiments, the first region is the area on the operating surface near the thumb when holding the device, so as to facilitate the user's use of the thumb to operate the buttons when holding the device.

[0102] The controller may also include a first button 210 for receiving user input for user interaction, such as pressing or touching.

[0103] The first button 210 is disposed on the operating surface of the operating section 120 for pressing and operating by the user's thumb. The first button 210 is disposed within the first region 121 so that when the handle is held, the user's thumb can extend from the edge of the first region 121 into the first region 121 to operate the first button 210.

[0104] When the user holds the handle, the first region 121 is positioned on the operating surface facing the base of the user's thumb, with the thumb extending into the operating surface from the edge of the first region 121. The operating surface has a preset-sized area to effectively prevent the thumb from extending into areas other than the first region 121 when the thumb moves within the first region 121.

[0105] In some embodiments, the first button 210 may include a main button 211 and an auxiliary button 212; the main button 211 is disposed in the first region 121 and located in the middle of the operation surface. The first region 121 and the second region 122 are both disposed around the middle of the operation surface, such that the first region and the second region are both fan-shaped or fan-like structures.

[0106] The main button 211 and the auxiliary button 212 are respectively installed in the first through hole 123. A control board is provided inside the housing 100. After the main button 211 and the auxiliary button 212 pass through the first through hole 123, they can abut against the corresponding structure on the housing 100 to trigger the corresponding function on the control board.

[0107] In some embodiments, when a user is using the handle, the tip of the user's thumb can press on the main button 211, and the thumb can be moved to press the auxiliary button 212.

[0108] In some embodiments, the first region 121 and the second region 122 are both disposed around the center of the operating surface, and the outer peripheral edges of the first region 121 and the second region 122 extend along the edge of the operating surface, so that the first region 121 and the second region 122 are both fan-shaped structures.

[0109] In some embodiments, the first region 121 and the second region 122 are each half of the operating surface. In this embodiment, the area of ​​the first region 121 is larger than the area of ​​the second region 122.

[0110] The handle may also include a positioner that emits positioning signals. The positioner can be configured to have its positioning signals collected by the host device of the head-mounted display to determine the position and / or motion information of the handle. This information may include optical information (e.g., visible, infrared, etc.), spatial information (e.g., light output), and motion information. A camera or video camera on the head-mounted display acquires the position and motion posture of the positioner, thereby generating corresponding commands and information within the head-mounted display.

[0111] After the signal emitted from the locator is collected by the host of the head-mounted display device, the host identifies the position and posture of the handle based on the collected positioning signal.

[0112] In some embodiments, the locator includes a first locator 310, which is used to emit a first positioning signal. The first locator 310 is disposed on the operating surface of the operating portion 120 opposite to the operating surface of the grip portion 110. Compared to the first area where the button is located, the first locator 310 is positioned away from the area of ​​the grip portion 110 corresponding to the base of the thumb when gripping, so that while facilitating thumb pressing, the signal emitted by the first locator is less likely to be blocked by the thumb.

[0113] In some embodiments, the positioner can be a positioning light, which can be an infrared light. In some embodiments, the positioner is a light of other colors. The first positioner 310 is disposed within the second through hole 124 on the operating surface.

[0114] In some embodiments, the locator may also be a device that emits other directional positioning signals.

[0115] In some embodiments, the first locator 310 is disposed within the second region 122 to avoid obstruction of the user's thumb.

[0116] In some embodiments, the grip portion 110 is arranged circumferentially for gripping by the user's fingers other than the thumb and the palm; the operating portion 120 has an operating surface on the side opposite to the grip portion 110 for pressing and operating by the user's thumb.

[0117] The operating surface includes a first region 121 and a second region 122 spaced apart; the edges of the first region 121 and the second region 122 both extend along the edge of the operating surface; a first button 210 is disposed in the first region 121 so that the user's thumb can reach into the first region 121 from the edge of the first region 121 to operate the first button 210; a first locator 310 is disposed in the second region 122 so as to avoid obstructing the user's thumb.

[0118] The first button 210 is located in the first area 121, and the first locator 310 is located in the second area 122. This effectively prevents the user's thumb from obstructing the first locator 310 in the second area 122, and ensures that the head-mounted display device can capture the position of the first locator 310. This effectively reduces the obstruction of the first locator 310 on the handle by the user's palm, reduces the number of first locators 310, and saves costs and resources.

[0119] The first region has a first edge, and the second region is located on the side of the first region opposite to the first edge. The first edge is positioned corresponding to the base of the thumb when gripping, and the base of the thumb presses against the first edge when gripping, with the thumb extending from the first edge into the operating surface.

[0120] In the direction from the first edge toward the second area, the plane where the operating surface is located is inclined away from the grip portion, so as to facilitate the thumb to press the first button in the first area and increase the probability that the first locator in the second area will not be blocked by the thumb.

[0121] In some embodiments, the second region 122 includes an adjacent first mounting area 1221 and a second mounting area 1222; the first mounting area 1221 and the second mounting area 1222 are arranged around the main button 211; the opposite sides of the first mounting area 1221 and the second mounting area 1222 are respectively close to one side of the first region 121; the first mounting area 1221 and the second mounting area 1222 are respectively provided with a first locator 310.

[0122] In this embodiment, the first locator 310 includes a first locating light 311 and a second locating light 312. The first locating light 311 is disposed in the first mounting area 1221, and the second locating light 312 is disposed in the second mounting area 1222.

[0123] In some embodiments, multiple first positioning lights 311 are provided in the first installation area 1221. Multiple second positioning lights 312 are provided in the second installation area 1222. The first locator 310 is set at different positions in the first area 121 to more accurately collect the positioning position and attitude, thereby better realizing human-computer interaction.

[0124] In some embodiments, the second mounting area 1222 is inclined toward the grip portion 110 in the direction away from the main button 211, such that there is an angle between the plane where the second mounting area 1222 is located and the plane where the first mounting area 1221 is located.

[0125] In other embodiments, the plane containing the second mounting area 1222 is inclined toward the gripping portion in a direction away from the first mounting area, such that there is an angle between the plane containing the second mounting area 1222 and the plane containing the first mounting area 1221.

[0126] In some embodiments, the plane containing the first mounting area 1221 and the plane containing the second mounting area 1222 form an angle, and the two intersecting planes form an angle between the plane containing the first positioning light 311 on the first mounting area 1221 and the plane containing the second positioning light 312 on the second mounting area 1222. At least two locators are respectively provided on each of the two mounting areas, thereby more effectively avoiding blind spots in the head-mounted display relative to the first locator, increasing the probability that the first locator on at least one surface will be sampled, thus more effectively ensuring the acquisition of the signal from the first locator 310 between the handle and the head-mounted display, more effectively avoiding obstruction of the first locator 310, and more effectively ensuring that the head-mounted display device can acquire the position and posture information on the handle.

[0127] In some embodiments, the second mounting area 1222 is configured such that it is located on the side of the first area 121 opposite to the user's palm. In this embodiment, when the user holds the grip portion 110, the fingertips will not come into contact with the palm. The location of the second mounting area 1222 on the side of the first area 121 opposite to the user's palm further prevents the user's palm from obstructing the locator on the second mounting area 1222.

[0128] In some embodiments, the positioners include multiple positioners disposed on the side of the operating surface facing inwards from the handle. Buttons protrude from the operating surface.

[0129] In some embodiments, the positioner is positioned within the operating surface at the end, eliminating the need for the light ring protruding from the handle body as in related technologies. This significantly reduces the probability of the positioner colliding with surrounding objects when held.

[0130] The operating part 120 has a recessed limiting groove 125 on the side facing away from the gripping part 110. The limiting groove 125 is connected to a plurality of second through holes 124. This facilitates the placement of locators that are interconnected via flexible circuit boards / wires, improving installation efficiency.

[0131] It should be noted that a through hole 126, penetrating the wall thickness of the grip portion 110, is provided within the limiting groove 125. One or more through holes 126 are provided. In this embodiment, two through holes 126 are provided. The through holes are used to electrically connect the positioner and the control device and / or the positioner on the handle.

Figure 9 This is a structural schematic diagram of the main housing of the present invention from one perspective. Figure 10 This is a structural schematic diagram of the main housing of the present invention from another perspective.

[0133] See Figures 1 to 10 In some embodiments, the grip portion 110 has an accommodating space for accommodating some components inside the handle, such as circuit boards, buttons, wires, batteries, etc.

[0134] In some embodiments, the grip portion 110 is circumferentially arranged for gripping by the user's four fingers other than the thumb and the palm. The grip portion 110 includes a grip area 111 and a positioning area 112 in the circumferential direction; the grip area 111 is configured for gripping by the user's fingers other than the thumb and the palm.

[0135] In some embodiments, the grip area 111 is used to allow the user's index, middle, ring, and little fingers to bend and fit against the outer surface of the grip portion 110, and the user's other fingers (excluding the thumb) and palm to bend so as to hold the grip portion 110 in the user's hand.

[0136] The outer periphery of the grip portion 110 is configured such that when the user grips the outer periphery of the grip portion 110, the user's fingers and palm are gripped in the grip area 111, and the user's fingers and palm are not inserted into the positioning area 112, so that the positioning area 112 is exposed outside the user's palm.

[0137] The positioning area is positioned close to the thumb, and the plane on which the operating surface is located is tilted away from the grip in the direction from the first edge toward the second area, so that there is a smaller angle between the positioning light in the positioning area and the positioning light on the operating surface, thereby increasing the probability that the head-mounted display device can simultaneously acquire the positioning light signal in the positioning area and the positioning light signal on the operating surface.

[0138] In some embodiments, the grip portion 110 is configured with different circumferences corresponding to different fingers to accommodate different finger lengths and effectively ensure the user's stable and reliable grip.

[0139] In some embodiments, the partial circumference of the grip portion 110 is greater than 15 cm, which may correspond to the line of contact between the user's middle finger and the grip portion 110.

[0140] In other embodiments, the partial circumference of the grip portion 110 is greater than 15 cm to correspond to the user's index or ring finger.

[0141] In some embodiments, the outer peripheral surface of the grip portion 110 has a curved structure to facilitate user gripping.

[0142] In some embodiments, the circumference of the outer periphery of the grip portion 110 gradually increases in the direction approaching the operation portion 120.

[0143] In some embodiments, the circumference of the outer periphery of the grip portion 110 gradually increases and then gradually decreases in the direction close to the operating portion 120, in order to adapt to changes in the length of human fingers.

[0144] In some embodiments, the grip portion includes a first finger separator 113, which is disposed on the grip portion 110. The first finger separator is used to place the first finger and the second finger on opposite sides of the first finger separator when the hand is gripping the grip.

[0145] In some embodiments, the first finger and the second finger are any two adjacent fingers of the hand, excluding the thumb.

[0146] In some embodiments, a first finger separator 113 is disposed in the gripping area 111 of the grip portion 110. The extension line of the first finger separator 113 wraps around the outer periphery of the grip portion 110 and around a line in the length direction of the grip portion 110. The first finger separator 113 is used to position and limit itself between two adjacent fingers of the user.

[0147] In some embodiments, the extension line of the first finger separator is a line extending along the first finger separator, around the outer periphery of the grip portion, and surrounding the length direction of the grip portion.

[0148] In some embodiments, the first finger separator 113 is disposed near the tail end 101 of the grip portion 110. The tail end 101 is the end of the grip portion 110 that faces away from the operating portion 120. In some embodiments, the first finger separator 113 protrudes from the outer periphery of the grip portion 110. The extension direction of the ridge line 105 of the first finger separator 113 is the direction of the extension line of the first finger separator 113. The extension line of the first finger separator 113 extends along the tangential direction of the outer periphery of the grip portion 110.

[0149] In some embodiments, the first finger separator 113 is positioned between the user's ring finger and little finger, and the first finger separator 113 is positioned so that the ring finger and little finger are located on both sides of the first finger separator 113 when the user holds the grip.

[0150] In other embodiments, the first finger separator 113 is positioned between the user's ring finger and middle finger, with the ring finger and middle finger located on either side of the first finger separator 113 when the user holds the grip.

[0151] In some other embodiments, the first finger separator 113 is positioned close to the operating portion.

[0152] In other embodiments, the first finger separator 113 is positioned between the user's index and middle fingers, with the index and middle fingers located on either side of the first finger separator 113 when the user holds the grip.

[0153] In some embodiments, the first finger separator 113 is positioned between the user's index and middle fingers, and the grip portion 110 also includes a second finger separator 114 disposed on the grip portion 110. The second finger separator is located between the first finger separator and the tail end.

[0154] In some embodiments, the second finger separator 114 is disposed in the grip area 111 of the grip portion 110.

[0155] In some embodiments, the extension line of the second finger separator is a line extending along the second finger separator, surrounding the outer periphery of the grip portion, and encircling the length direction of the grip portion. The second finger separator 114 is used to position and limit between two adjacent fingers of the user. The second finger separator is used to place the user's little finger and ring finger on either side of the second finger separator when the hand is gripped.

[0156] In some embodiments, the second finger separator 114 protrudes from the outer periphery of the grip portion 110. The extension direction of the ridge 105 of the second finger separator 114 is the direction of the extension line of the second finger separator 114. The extension line of the second finger separator 114 extends along the tangential direction of the outer periphery of the grip portion 110.

[0157] In other embodiments, the second finger separator 114 may be positioned between the user's ring finger and middle finger, and the first finger separator 113 may be positioned on either side of the second finger separator 114 when the user holds the hand.

[0158] In some embodiments, the grip portion 110 is provided with both a first finger separator 113 and a second finger separator 114. The second finger separator 114 is located between the first finger separator 113 and the tail end 101. The first finger separator 113 is used to limit the user's index and middle fingers, and the second finger separator 114 is used to limit the user's little finger and ring finger.

[0159] The first finger separator 113 and the second finger separator 114 simultaneously position the user's grip, enhancing the feel of the grip and effectively limiting the user's grip position on the grip part 110.

[0160] In this embodiment, a first through hole 115 is provided on the outer periphery of the grip portion 110, and the first through hole 115 is disposed in the grip area 111; the first through hole 115 is disposed at the end of the grip area 111 facing the operation part 120. The first through hole 115 extends into the interior of the grip portion 110. The first through hole 115 is used to install a button. The first through hole 115 is disposed on the side of the first finger separator 113 facing the tail end 101 of the grip portion 110.

[0161] A second through hole 116 is provided on the outer periphery of the grip portion 110 for mounting buttons. The second through hole 116 is provided in the grip area 111. The second through hole 116 is provided on the side of the first finger separator 113 facing the operation portion 120. The first through hole 115 and the second through hole 116 are respectively provided on both sides of the first finger separator 113.

[0162] In some embodiments, the first perforation 115 and the second perforation 116 are used to install buttons or keypads. The button located at the first perforation 115 is for operation by the user's middle finger. The button located at the second perforation 116 is for operation by the user's index finger.

[0163] In some embodiments, the grip portion 110 is provided with a second button 220 and a third button 230 on both sides of the first finger separator 113, respectively. The second button 220 is located on the side of the first finger separator 113 facing the tail end 101. The third button 230 is located on the side of the first finger separator 113 facing away from the tail end 101. The second button 220 is disposed in the first through hole 115, and the third button 230 is disposed in the second through hole 116.

[0164] In some embodiments, the gripping area 111 of the gripping part 110 is provided with only a first through hole 115 or a second through hole 116.

[0165] In some other embodiments, the grip portion 110 does not need to be equipped with buttons, and the grip area 111 is not provided with a first through hole 115 and a second through hole 116.

[0166] In some embodiments, the grip portion 110 is further provided with a third through hole 117, which is provided in the positioning area 112. The third through hole 117 is provided on the side of the grip portion 110 near the tail end 101. The third through hole 117 is located on the side of the extension line of the first finger separator 113 facing the tail end 101 of the grip portion 110.

[0167] In some embodiments, the grip portion 110 is further provided with a fourth through hole 118, which is disposed on the side of the third through hole 117 facing the operation portion 120.

[0168] The locator also includes a second locator 320, which is disposed on the grip portion and is positioned away from the operating portion along the length direction compared to the first finger separator.

[0169] The second positioner is used to emit a second positioning signal, and the first positioner is used to emit a first positioning signal. The second positioning signal and the first positioning signal are collected by the host of the head-mounted display device to determine the position and attitude of the handle.

[0170] In some embodiments, the first locator 310 is disposed on the operating surface of the operating part 120, and its position is relatively concentrated, so the signal spots formed after the host acquires data are also relatively concentrated. The second locator 320 is disposed on the grip part 110, and the second locator 320 is located on the side of the extension line of the first finger separator 113 facing the tail end 101 of the grip part 110, so that the first locator 310 and the second locator 320 are located in different planes. At the same time, the distance between the first locator 310 and the second locator 320 effectively avoids mutual interference between the first locator 310 and the second locator 320. The signal spots formed after the host acquires data also have a spot away from the concentrated area, which makes it easier for the host to identify the posture of the grip part relative to the operating part through the acquired signal spots. In this way, the posture of multiple first locators can be calculated, improving the accuracy and calculation efficiency of the handle's position and posture recognition.

[0171] The second locator is positioned away from the operating part along the length of the grip portion. The distance between the second locator and the tail end is less than the distance between the first finger separator and the tail end, so that the second locator is closer to the tail end of the grip portion than the first finger separator, thereby increasing the probability that the second locator will not be obstructed. At the same time, the distance between the first locator 310 and the second locator 320 is maintained, effectively avoiding mutual interference between the first locator 310 and the second locator 320.

[0172] In some embodiments, the distance between the extension line of the second positioner 320 and the second finger separator 114 is less than 10mm, so as to effectively ensure the alignment or misalignment of the second positioner and the second finger separator, maintain the distance between the second positioner and the second finger separator, and maintain the distance between the first positioner and the second positioner, so as to facilitate the identification of the handle position and posture.

[0173] In other embodiments, the distance between the second finger separator and the tail end is smaller than the distance between the second locator and the tail end, so that the second finger separator is closer to the tail end of the grip portion than the second locator.

[0174] In other embodiments, the distance between the second locator and the tail end is smaller than the distance between the second finger separator and the tail end, so that the second locator is closer to the tail end of the grip portion than the second finger separator.

[0175] In some embodiments, the second locator is located on the extension line of the second finger separator, which is a line extending along the second finger separator, surrounding the outer periphery of the grip portion, and encircling the length direction of the grip portion. The second finger separator is used to limit the position between two adjacent fingers. The second locator is located on the extension line of the second finger separator, which can effectively prevent the user's fingers from obstructing the second locator and increase the probability that the second locator will not be obstructed.

[0176] The second positioner 320 is disposed in the positioning area 112 of the grip portion 110. The second positioner 320 is disposed in the third through hole 117 of the positioning area 112.

[0177] The grip portion 110 includes a grip area 111 and a positioning area 112 in the circumferential direction. The grip area 111 is configured for the user's fingers other than the thumb and the palm to grip. The second locator 320 is disposed in the positioning area 112 to avoid obstructing the user's fingers. This ensures that when the user grips the grip portion 110, the second locator 320 is exposed outside the user's palm, effectively ensuring that the head-mounted display device can capture the position of the second locator 320. This effectively reduces the obstruction of the second locator 320 on the handle by the user's palm, reduces the number of second locators 320, and saves costs and resources.

[0178] The grip portion 110 also includes a third positioner 330, which is disposed on the side of the grip portion. The third positioner is located on the side of the second positioner facing the operating part. The third positioner is used to emit a third positioning signal, which is collected by the host of the head-mounted display device. Two positioners are arranged on the handle approximately along its length. The algorithm can predict the relative relationship between the line connecting these two positioners and the length direction of the handle. By identifying the line connecting the signal spots of these two positioners, the posture of the grip portion can be quickly determined without referring to the signal spots of the first positioner, thereby improving the accuracy and computational efficiency of the handle's position and posture recognition.

[0179] In some embodiments, the two positioners are distributed approximately along the length direction, meaning the third positioner is closer to the operating part than the second positioner, and the second positioner is closer to the tail end than the third positioner. This approximately length-direction distribution is easier to identify than a circumferential distribution.

[0180] The third positioner is used in conjunction with the first and second positioners to help the host of the head-mounted display device identify the position and orientation of the handle.

[0181] In some embodiments, the host can input the signal spot set of the first locator, the second locator, and the third locator into the pose prediction model for pose recognition. Since the second and third locators are relatively separated from the multiple first locators on the operating surface, the separated signal spots will improve the speed and accuracy of recognition.

[0182] In some embodiments, the host can first identify the pose parameters of the gripping part through the signal spot sets of the second and third locators, and then perform pose recognition based on the pose parameters of the gripping part and multiple signal spots of the first locators. Since the pose parameters of the gripping part are identified first, and then pose recognition is performed based on the pose parameters of the gripping part and multiple first positioning signal spots, the speed and accuracy of recognition can be improved.

[0183] In some embodiments, the distance between the third locator and the tail end is less than the distance between the first finger separator and the tail end, so that the third locator is closer to the tail end of the grip portion than the first finger separator, thereby increasing the probability that the third locator will not be obstructed.

[0184] In some embodiments, a second finger separator is disposed on the grip portion, located between the first finger separator and the tail end; the distance between the third locator and the tail end is less than the distance between the first finger separator and the tail end, and the third locator is closer to the tail end of the grip portion than the first finger separator. The distance between the second finger separator and the tail end is less than the distance between the third finger separator and the tail end, and the second finger separator is closer to the tail end of the grip portion than the third locator, such that the third locator is located between the extension lines of the first and second finger separators.

[0185] In some embodiments, the distance between the second finger separator and the tail end is less than the distance between the second locator and the tail end, so that the second finger separator is closer to the tail end of the grip portion than the second locator.

[0186] In other embodiments, both the second locator 320 and the third locator 330 are located between the extension lines of the first finger separator 113 and the second finger separator 114.

[0187] In this embodiment, the third locator 330 is disposed in the positioning area 112 and located on the extension line of the middle finger, effectively avoiding obstruction of the third locator 330.

[0188] In this embodiment, the third locator 330 is disposed within the fourth through hole 118. In some embodiments, the third locator 330 is disposed directly in the positioning area 112 of the grip portion 110.

[0189] In this embodiment, the positioning light also includes a third positioning device 330. The circumference of the outer periphery of the grip portion 110 gradually increases in the direction close to the operation portion 120. The third positioning device 330 is located on the side of the second positioning device 320 facing the operation portion 120, thereby effectively preventing the user's finger from obstructing the third positioning device at this position.

[0190] The connection between the second locator 320 and the third locator 330 is located between the user's palm and the fingers other than the thumb when holding the device, thereby effectively avoiding obstruction of the second locator 320 and the third locator 330 and effectively ensuring the simultaneous acquisition of the positions of the second locator 320 and the third locator 330.

[0191] The distance between the second locator 320 and the third locator 330 is 22mm. This ensures sufficient spacing between the second locator 320 and the third locator 330 to avoid the formation of light spots between them during identification, thus facilitating the identification of the second locator 320 and the third locator 330.

[0192] In some embodiments, the angle between the line connecting the second positioner 320 and the third positioner 330 and the operating surface is 30-90 degrees.

[0193] In some embodiments, the angle between the line connecting the second locator 320 and the third locator 330 and the operating surface is less than 30 degrees, so that the angle between the grip 110 and the operation is smaller, making it easier for the thumb to press.

[0194] In some embodiments, one or more locators are provided at one end of the grip portion 110 facing away from the operation portion 120, and the locators are located outside the little finger when the grip portion 110 is held.

[0195] In other embodiments, one or more locators are provided at one end of the grip portion 110 facing the operation portion 120, the locator being located outside the index finger and between the index finger and the operation portion 120.

[0196] It should be noted that, based on the above description, the location and number of locators can be arbitrarily combined. The configuration of the first locator 310, the second locator 320, and the third locator 330 can be arbitrarily combined.

[0197] In some embodiments, the grip portion 110 includes a main housing 107 and a cover plate 108 that covers one side of the main housing 107. The cover plate engages with the main housing to form a receiving cavity, in which electronic components, power supplies, and other structures are formed.

[0198] In some embodiments, the side of the accommodating cavity opposite to the tail end is an opening, and the operating part is disposed on the opening.

[0199] In some embodiments, the gap formed at the joint of the main housing 107 and the cover plate 108 is a splice seam 104. A first finger separator 113 is disposed on the main housing 107, and a second positioner 320 is disposed on the cover plate 108. The second positioner and the first finger separator are located on both sides of the splice seam.

[0200] In other embodiments, the first finger separator 113 and the second finger separator 114 are both disposed on the main housing 107. The second positioner 320 and the third positioner 330 are both disposed on the side of the splice seam 104 facing away from the main housing 107.

[0201] In some embodiments, the grip portion 110 includes a main housing 107 and a cover plate 108 that covers one side of the main housing 107. A first through hole 115, a second through hole 116, and a third through hole 117 are all provided on the main housing 107. The cover plate 108 is attached to the side of the main housing 107 facing the cover plate 108 and covers the second locator 320 and the third locator 330. The cover plate 108 is a structure made of a transparent or translucent material.

[0202] In some embodiments, the cover plate 108 is detachably fitted onto the main housing 107, and a battery compartment for accommodating the battery is formed on the side of the main housing 107 facing the cover plate 108. The cover plate 108 fits onto the main body and covers the battery compartment.

[0203] In some embodiments, the battery is housed inside the grip housing 107 and is rechargeable. A cover 108 is not required on the housing 107.

[0204] In some embodiments, a step is formed on the edge of the main housing 107 facing the cover plate 108, and the cover plate 108 is attached to the step so that the outer side of the cover plate 108 and the main housing 107 are flush and smoothly transitioned. The second positioner 320 and the third positioner 330 are both provided at the step.

[0205] In some embodiments, the grip portion 110 may include two opposing first housings and a second housing. The opposing sides of the first housing and the second housing are fitted together. Open cavities are formed on the opposing sides of the first housing and the second housing, and an accommodating space is formed between the first housing and the second housing. A first through hole 115 and a second through hole 116 are formed on the first housing, and a third through hole 117 and a fourth through hole 118 are formed on the second housing.

[0206] In some embodiments, the cover plate 108 is provided with a ridge 105, and the ridge 105 of the cover plate 108 and the axis of the grip portion 110 in the length direction are located in the same plane; the second locator 320 is located between the splice seam 104 and the ridge 105.

[0207] In other embodiments, the ridge 105 of the cover plate 108 and the axis of the grip portion 110 along its length are located on different planes. Both the ridge 105 of the cover plate 108 and the axis of the grip portion 110 along their length extend from the tail end toward the operating portion.

[0208] The distance between the second locator and the ridge line is greater than the distance between the second locator and the seam. When the user holds it on the grip, it can effectively prevent the user's palm from obstructing the second locator.

[0209] In some implementations, the main housing also includes a second finger separator located between the first finger separator and the tail end. The second finger separator allows the little finger and ring finger of the hand to rest on either side of it when the hand is gripping the device. The projection of the second locator onto the main housing is located between the first and second finger separators. By positioning the user's hand relative to the first and second locators, the alignment of the user's hand with the second and third locators is effectively improved, increasing the probability that the second and third locators are not obstructed.

[0210] In some embodiments, the third positioner is located on the side of the second positioner facing the operating part, and is used to emit a third positioning signal; the straight line connecting the third positioner and the second positioner intersects the straight line containing the splice seam, and the angle of intersection is less than 5 degrees. This arrangement ensures that the straight line connecting the third positioner and the second positioner is close to the splice seam, effectively shielding the third and second positioners when held.

[0211] In some embodiments, the main housing further includes a second finger separator located between the first finger separator and the tail end. The second finger separator is used to allow the little finger and ring finger of the hand to rest on either side of the second finger separator when the hand is gripping it. The projection of the second locator on the main housing is located between the first and second finger separators. The second finger separator improves the grip feel and further positions the user on the grip portion, thereby increasing the probability that the locator will not be obstructed.

[0212] In some embodiments, the third positioner 330 is located on the side of the second positioner 320 facing the operation part 120. The distance between the second positioner 320 and the ridge line 105 is greater than the distance between the second positioner 320 and the seam 104; the distance between the third positioner 330 and the ridge line 105 is less than the distance between the second positioner 320 and the seam 104. This ensures that the distance between the third positioner 330 and the seam 104 is greater than the distance between the second positioner 320 and the seam 104, effectively preventing obstruction of the third positioner 330.

[0213] In some embodiments, the third positioner is located on the side of the second positioner facing the operating part, and the third positioner is used to emit a third positioning signal.

[0214] The second and third buttons are respectively located on either side of the first finger separator. The second button is located on the side of the first finger separator facing the tail end. When the hand is held, the index and middle fingers of the hand rest on either side of the second finger separator. The third positioning device is located in the first direction of the third button, which is the direction pointed to by the tip of the middle finger when the hand is held. The third positioning device is positioned corresponding to the third button to effectively prevent other fingers of the user from obstructing the third positioning device.

[0215] Figure 11 This is a schematic diagram of the structure of the FPC of the present invention.

[0216] See Figures 1 to 11 Multiple first locators are provided in the second area 122 of the operating surface, and the multiple first locators are arranged on the same FPC (flexible printed circuit board, 340). A limiting groove 125 is recessed on the side of the operating part 120 facing away from the gripping part 110. The FPC (340) is accommodated and limited in the limiting groove 125, thereby facilitating the installation and positioning of the first locators. The FPC (340) is pasted in the limiting groove 125.

[0217] The limiting groove is designed to facilitate the installation of the FPC on the handle. Multiple first positioners are set on the same FPC so that they can be quickly installed on the operating surface along with the FPC, thus facilitating the installation of the first positioners.

[0218] A control board is provided inside the housing 100. A through hole 126 is provided in the limiting groove 125, which penetrates the wall thickness of the grip part 110. The FPC (340) passes through the through hole 126 and is connected to the control board.

[0219] In some embodiments, the first locator 310, the second locator 320, and the third locator 330 are all disposed on the FPC, facilitating their rapid installation along with the FPC.

[0220] The operating part 120 has a recessed mounting groove on the side facing away from the gripping part 110, and the mounting groove communicates with the limiting groove 125; the first locator is housed in the mounting groove, and the edge of the FPC (340) or the first locator abuts against the side wall of the mounting groove to limit the FPC and the first locator.

[0221] The edge of the FPC or the first positioner abuts against the side wall of the mounting slot to facilitate the positioning of the FPC and the first positioner, and to maintain the stability and reliability of the position of the first positioner, so as to enable the head-mounted display device to more accurately identify the position of the handle.

[0222] Figure 12 This is a cross-sectional schematic diagram of the positioner of the present invention on an FPC.

[0223] See Figure 12 The locator is surrounded by a light-shielding element 400, which is located on the side of the FPC where the first locator is mounted and covers the first locator. The light-shielding element 400 is designed to concentrate the light from the locator, thereby more effectively ensuring that the head-mounted display device can collect light from the handle. The light-shielding element 400 also serves to protect the first locator.

[0224] It should be noted that, in some embodiments, a light-transmitting element 500 is provided on the operating surface of the operating unit 120. The light-transmitting element 500 is a structure made of transparent or translucent material. The light-transmitting element 500 covers the operating surface of the operating unit 120. Light from the positioner on the operating surface can pass through the light-transmitting element 500.
