Description

Technical Field

[0001] The present invention relates to the technical field of electronic digital data processing, and in particular to a VR experience device with autonomous adjustment capability and a control method thereof. Background Art

[0002] With the rapid development of the leisure and entertainment industry, many terminal simulators for virtual reality environments have emerged to meet users' needs for a stronger sense of control and immersion.

[0003] Considering that VR experience is based on multiple devices, including but not limited to head-mounted components, position-limiting components, and sensor components configured in various locations, it is often difficult for it to be used in homes. Instead, it appears more often in various experience venues and is used as a simulation device.

[0004] However, in the VR experience occasions of the prior art, even if there is a large space to spread out the equipment, most of them cannot realize the autonomous adjustment of the head-mounted components and position-limiting components according to the parameter information of different users, such as the height adjustment of the seat, the height or slope adjustment of the walking platform, or the falling position adjustment of the VR helmet, etc., and the universality is not strong. In particular, most VR seats on the market generally only set the use range through fixed standard parameters, without considering the different performance of the same seat in terms of comfort and safety due to different parameters such as body shape and weight of different users; for users of different heights and body shapes, in order to accurately adjust the equipment components to a position suitable for themselves, manual adjustment is required, and both the adjustment process and the final unsuitable position are poor experiences for users. More importantly, for some users who are obviously not suitable for using VR experience equipment, such as users with large or small bodies, it is generally impossible to coordinate suitable seats for them in time, which leads to safety risks for people and equipment.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with embodiments, but the protection scope of the present invention is not limited thereto.

[0020] like Figure 1 As shown, the present invention relates to a VR experience device with autonomous adjustment capability, the VR experience device comprising: One or more VR head-mounted devices 1, used to be worn on the user's head and provide a single VR interactive screen; One or more VR experience units, used to provide a single VR interaction space or realize the linkage of multiple VR interaction spaces; One or more seats 2, corresponding to the VR experience unit settings, for providing a user with a sitting position and cooperating with the VR interactive screen to feedback posture adjustment in a sitting position; One or more information collection units, used to collect user information; A control terminal is used to configure the VR experience unit, allocate the VR experience unit and the VR head-mounted device 1 based on the user information collected by the information collection unit, adjust the seat 2 and the VR head-mounted device 1 to adapt to the user, and control the working status of the seat 2 and the VR head-mounted device 1.

[0021] In the present invention, it is first necessary to explain that one or more VR experience units are configured in a device, and each VR experience unit is equivalent to an independent VR experience space, which can provide a single user with a single VR interaction space, and can also satisfy multiple users to achieve linkage in a corresponding number of VR experience units. This linkage refers to linkage in the virtual reality space, that is, a shared map or a shared scene.

[0022] In the present invention, each VR experience unit is configured with a VR head mounted device 1 and a seat 2. The VR head mounted device 1 provides the user with a single VR interactive screen, and the seat 2 provides the user with a sitting position. During the actual VR experience process, the seat 2 may adjust its posture as the experience content changes.

[0023] In the present invention, the information collection unit includes but is not limited to cameras, sensors, etc., and the user information it needs to obtain includes but is not limited to basic user information, such as height, weight, facial information (if permitted), and user posture feedback data, location information, etc.

[0024] In the present invention, the VR experience unit is configured by the control end. The configuration here includes but is not limited to configuring the applicable items and applicable groups (age, body shape, etc.) of each VR experience unit, and simultaneously opening the interactive permissions of some or all VR experience units to meet the experience needs of different audience groups. Each VR experience unit can operate independently without being affected by other VR experience units, or multiple VR experience units can cooperate. During the process, the control end allocates VR experience units and VR head-mounted devices 1 based on the collected user information, and adjusts the seat 2 and the VR head-mounted device 1 to adapt to the user based on the user information to eliminate safety hazards. During the operation of a single VR experience unit, the control end obtains real-time information collected by the information collection unit, and controls the working status of the seat 2 and the VR head-mounted device 1 based on preset conditions.

[0025] like Figure 2 As shown, the information collection unit includes a collection area 3, a weight collector 4 is provided at the bottom of the collection area 3, a first camera 5 for collecting height data is provided at the side of the collection area 3, and a second camera 6 for collecting body circumference data is provided at the top of the collection area 3; a human body model is constructed based on the data collected by the information collection unit, and a seat 2 and a corresponding VR experience unit are allocated based on the human body model.

[0026] A lifting mechanism 7 is provided in the collection area 3 cooperating with the first camera 5 ; a circular track 8 is provided in the collection area 3 cooperating with the second camera 6 , and the circular track 8 is coaxially arranged with the weight collector 4 .

[0027] Based on the constructed human body model, a data set of the user's fitted leg length, seat height and maximum circumference in a sitting position is obtained, and the seat 2 and the VR head-mounted device 1 are adjusted based on the data set.

[0028] In the present invention, the collection area 3 is set at the entrance of the VR experience scene, and the weight collector 4 at the bottom is used to collect the user's weight, the first camera 5 on the side is used to collect the height data, and the second camera 6 on the top is used to collect the body circumference data. A human body model can be approximately constructed through the collected height data and body circumference data. The human body model here can be used to distinguish between infants and adults, and can distinguish people whose weight may exceed the maximum load of some seats 2, thereby facilitating the allocation of seats 2 and corresponding VR experience units.

[0029] In the present invention, the lifting mechanism 7 is used to control the lifting of the first camera 5 so that it can obtain the maximum height of the user, and the circular track 8 is used to satisfy the second camera 6 to collect body circumference data at various angles downward. At this time, the human body model constructed is relatively accurate; the coordination between the lifting mechanism 7 and the first camera 5, and the coordination between the circular track 8 and the second camera 6 are contents that are easy to understand for technical personnel in this field, and can be completed through relevant transmission mechanisms. Technical personnel in this field can set them according to their needs; in order to ensure the relative accuracy of the data and the convenience of data collection, the circular track 8 is coaxially arranged with the weight collector 4.

[0030] In the present invention, more feature information can be collected based on the constructed human body model, among which the user's fitted leg length and maximum circumference in a sitting position can be used to screen a suitable seat 2, and the seat height is convenient for judging the height to which the VR head-mounted device 1 falls, thereby improving the user's experience.

[0031] like Figure 3 , Figure 4 As shown, the adjustment of the seat 2 and the VR head-mounted device 1 is described below.

[0032] In the present invention, any of the seats 2 includes a seat 2 body, which should first have maximum load data and be screened based on the user's weight; A liftable support rod 9 is provided at the bottom of the main body of the seat 2, which can adjust the height of the seat 2 from the standing position. For users of different heights, the height of the liftable support rod 9 can be adjusted to achieve better adaptation, making it easier for users to enter the seat 2; The handle 10 and the armrest are detachably provided on the front and side of the seat 2. Generally, one of them can be selected to adapt to different experience projects. The opening degree can also be adjusted according to the user's body circumference data to ensure the comfort of the user in the sitting position; A detachable arm guard 11 may also be provided behind the seat 2 to adapt to different experience projects, especially some projects that require sitting posture protection. The arm guard 11 may also adjust the opening degree according to the user's body circumference data; In the present invention, the arrangement of the relevant components of the seat 2 is easily understood by those skilled in the art, such as the liftable support rod 9 can be completed by a cylinder or a mechanical structure, and those skilled in the art can arrange it by themselves according to their needs; Here, an implementation method of a liftable support rod 9 is provided. The liftable support rod 9 contains an electric cylinder inside. The lifting height is controlled by the encoder on the main shaft or the working time of the electric cylinder. In the former, the encoder is installed on the main shaft. Every time the main shaft rotates one circle, the encoder outputs a fixed number of pulses. And every time the main shaft rotates one circle, the distance that the seat 2 rises or falls is also fixed. Therefore, by calculating the number of pulses output by the encoder, the distance that the lifting column of the liftable support rod 9 rises or falls can be calculated, so as to set the desired height of the seat 2. The latter ensures that the speed of the lifting column rising or falling is fixed, and the height setting of the seat 2 is completed by controlling the working time. Similarly, the opening and closing degree of the handle 10, armrest or arm guard 11, that is, the inner circumference when closed, is adjusted according to the user's waist circumference data, and then the holding range of the handle 10, armrest or arm guard 11 is adjusted according to the user's weight information or the distance from the chest to the back, so that the handle 10, armrest or arm guard 11 can be close to the user's abdomen, so that it will not be too close to affect the user experience, while allowing the user to be better protected in interactive scenarios with larger motion ranges.

[0033] In the present invention, the handle 10, armrest or arm guard 11 are configured according to needs, and generally at least one of them is provided on the main body of the seat 2; if necessary, a detachable footrest can be provided at the lower front part of the seat 2 to adapt to different experience items, which is easily understood by those skilled in the art.

[0034] In the present invention, a hanging slot 12 is provided in conjunction with the VR head mounted device 1, and the VR head mounted device 1 is lowered and folded up through a liftable traction assembly 13 at the top of the hanging slot 12. When lowered, the VR head mounted device 1 generally falls to a safe position in front of the user, and when folded up, the VR head mounted device 1 can be cleaned or treated for theft prevention. The liftable traction assembly 13 is a content that is easily understood by those skilled in the art, and is generally a motor and a traction rope provided at the output end of the motor to realize the lowering and folding of the VR head mounted device 1 and the hanging slot 12. In the present invention, a position sensor is arranged in the hanging groove 12. Only when the user hangs the VR head mounted device 1 and the position sensor feeds back a position signal, the VR head mounted device 1 will be folded. When the experience starts, if the position sensor feeds back no signal, the experience preparation stage will be entered.

[0035] The VR experience unit includes a VR interaction space that accommodates any group of seats 2 and a VR head-mounted device 1. Sensor components are distributed in the VR interaction space, and cooperate with the sensor components in any VR interaction space to obtain edge sensor signals and connect with the control end.

[0036] More than one VR interaction space initiates a request, and the control end allocates a token to each VR interaction space that initiates the request. Each VR interaction space that initiates the request is connected to a temporary local area network through a token. The sensor components of each VR interaction space connected to the temporary local area network obtain edge sensor signals and then feed them back to the control end.

[0037] Any of the VR interactive spaces is equipped with an indication mechanism.

[0038] In the present invention, the VR experience unit is actually a subspace in the VR experience device, which may or may not have a boundary. Each VR experience unit accommodates a group of seats 2 and a VR head-mounted device 1, providing a user VR interaction space, in which sensor components are distributed for obtaining user information and providing real-time feedback. This real-time feedback includes but is not limited to providing experience images in the VR head-mounted device 1 and multi-axis motion control of the seat 2.

[0039] In the present invention, when there is a demand for multiple VR interactive spaces to experience a joint linkage, each VR experience unit raises its hand, that is, initiates a request. For each request end, the control end allocates a token to each allowed (compliant, such as an experience project) VR interactive space that initiates the request, and then the VR interactive spaces that initiate the request are connected to a temporary local area network through the token. The sensor components of each VR interactive space connected to the temporary local area network obtain edge sensor signals and then feed them back to the control end together, so that the control end collaborates to complete the linkage.

[0040] In the present invention, in order to quickly allow users to enter the action and provide a better interactive experience and onlooker atmosphere, an indication mechanism can be configured for each VR interactive space, including but not limited to a loudspeaker, a light strip, etc.

[0041] The present invention also relates to a control method for the VR experience device with autonomous adjustment capability, and the method is described below in conjunction with the steps.

[0042] S1 collects user information with the information collection unit. If the user does not meet the basic conditions for using the VR experience device, the user is denied access and S1 is repeated or S8 is performed. Otherwise, the next step is performed. The user information collected here includes but is not limited to the user's body shape data, which is used to screen out users who are too thin (including young children) and users who are too heavy and not suitable for the experience, to ensure the safety of users and reduce the potential safety hazards of VR experience equipment; The basic conditions here can be set by the staff, and body shape, age, etc. are not absolute screening criteria.

[0043] S2 obtains a data set of the user's fitted leg length, sitting height and maximum circumference in a sitting position based on the user information; Here, the fitted leg length and the maximum circumference in the sitting position are used to select a suitable seat 2 and a corresponding VR experience unit, and the sitting height is used to control the descending height of the VR head-mounted device 1; It should be noted that the configuration of the VR experience unit will be carried out in advance, and the configuration content includes but is not limited to the experience content, experience time, whether linkage is allowed, etc.

[0044] S3 The control end analyzes the confidence of the data group. If the confidence is higher than a preset value, a VR experience unit is allocated and the next step is performed. Otherwise, S1 is repeated or S8 is performed. S4 adjusts the seat 2 and the VR head mounted device 1 based on the data group, so that the seat 2 meets the user's fitted leg length and the maximum circumference in the sitting posture, and the VR head mounted device 1 meets the user's sitting height; after the adjustment is completed, the VR experience unit issues an instruction; In the present invention, considering the limitations of application scenarios, the user's weight measurement and body shape data acquisition are bound to fluctuate. On the one hand, it is necessary to perform operations such as data cleaning and averaging. On the other hand, it is also necessary to analyze the confidence of the data group. The confidence here is reflected in whether the combination of the constructed human body model and weight, height and circumference is credible. This can be achieved through a trained neural network. When the confidence is higher than the preset value, the user can be prepared to be guided into the assigned VR experience unit. During the process, the seat 2 and the VR head-mounted device 1 are adjusted to a suitable position to facilitate the user to sit in the seat 2 and take off the VR head-mounted device 1, which also saves preparation time before the user experience.

[0045] S5 The user enters the VR experience unit, sits in seat 2, fine-adjusts seat 2, and wears VR head-mounted device 1; if there is a need for linkage with other VR experience units, wait for other linked VR experience units to be ready and proceed to the next step, otherwise proceed to S7; S6 All VR experience units corresponding to linkage requirements are ready, and a request is initiated within the preset time. The control end allocates a token and confirms entry into the temporary LAN; S7 The control end obtains information of one or more VR experience units, and controls the working status of the corresponding seat 2 and VR head mounted device 1 until the single experience ends; In the present invention, the user takes off the VR head-mounted device 1, and enters the preparation state after the in-place sensor feedbacks a low level. The VR experience device can meet the linkage of VR experiences of multiple users, and can also complete the independent VR experience of a single user. It is necessary to raise the hand in the preparation state and obtain an access token; each VR experience unit feedbacks data through its corresponding sensor component, obtains the experience picture transmitted by the control end, and receives the control of its seat 2 by the control end.

[0046] S8 The user returns the VR headset 1 to its original position, and the process ends; Specifically, the VR head mounted device 1 is returned to the hanging groove 12 and the in-position sensor feeds back a high level signal, and then the hanging groove 12 will move upward and be pushed out to the designated cleaning position for cleaning.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
