Detailed Description

The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.

The virtual reality system can be divided into four types, namely an immersion type virtual reality system, an augmented reality type virtual reality system, a desktop type virtual reality system and a distributed virtual reality system according to different functions. The immersive virtual reality system provides a user with a completely immersive experience, so that the user has a feeling of being placed in a virtual world. The helmet display is obviously characterized in that the helmet display is utilized to seal the vision and the hearing of a user to generate virtual vision. Meanwhile, the hand feeling channel of the user is sealed by the data glove, and virtual touch feeling is generated. The system adopts the voice recognizer to enable a user to issue an operation command to the system host, and meanwhile, the head, the hand and the eyes are tracked by the corresponding head tracker, the hand tracker and the eye sight direction tracker, so that the system achieves the real-time performance as much as possible. A common immersive system is a system based on a head-mounted display, which uses binocular parallax between left and right eyes to form a stereoscopic impression.

For virtual reality systems, such as immersive virtual reality systems, VR display systems on the user side typically include a modeling module. The modeling module is used for establishing three-dimensional objects required in the virtual environment world, such as: text, cards, object models, three-dimensional environments, etc. A Graphical User Interface (GUI) in the modeling module displays all buttons, menus, text, cards, etc. The GUI is also responsible for providing logical modules that can be relied upon for the function and interaction of these elements. For example, the logic modules include a text parameter control module and a 3D rendering module. The text parameter control module is mainly used for controlling the size of displayed text, such as: the height, width, etc. of the text. The 3D rendering module mainly manages the entire 3D engine, and the main camera of the VR scene determines the objects to be rendered and the details of the encapsulated rendering of the 3D engine and sends them to the 3D rendering module through the rendering pipeline, and also provides access through the pixel and vertex shaders. The modeling module may also include other functional modules or elements, such as an input module, an artificial intelligence module, and so forth.

In addition to the display system, the virtual reality system also includes a sensory simulation system that is matched to the VR display system. The sensory simulation system is used to provide various senses, such as hearing, taste, smell, and touch, etc., to a user. In addition, the virtual reality system also comprises a space moving system, when a user is immersed in a scene constructed by the display system, the user can make corresponding action reactions according to different situations in the scene, such as walking, running, jumping, lying prone and the like, and at this time, if the user only makes the actions and the body does not move correspondingly, the body of the user can be inconsistent with the feeling of the user, and the user experience can be reduced. For the existing virtual reality experience system, due to the limitations of the system structure, the connection mode and the like, the spatial movement range of the user is very limited, and therefore the position movement which can be felt by the user is also very limited. In addition, the virtual reality system should adopt a synchronous and coordinated control mode to control different components. Synchronization includes synchronization of the virtual scene presented by the display system with the user's perception, synchronization of user actions with the virtual scene, and synchronization of actions between different components.

In order to widen the spatial movement range of a user, enhance the spatial experience and the tactile experience of the user and simultaneously realize the control of synchronous coordination, the invention provides a VR scene experience system, which comprises VR glasses and a virtual scene display module, wherein the VR glasses are used for providing a virtual scene; the first mechanical arm is used for assisting the human body to move in a three-dimensional space; the second mechanical arm is used for providing a physical prop for a human body; and the control device is connected with the first mechanical arm and the second mechanical arm and is used for respectively controlling the three-dimensional space movement of the first mechanical arm and the three-dimensional space movement of the second mechanical arm.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic diagram illustrating an implementation structure of a VR scene experience system in an embodiment of the present invention, fig. 2 is a schematic diagram illustrating a connection relationship of the VR scene experience system in an embodiment of the present invention, and the connection relationship schematic diagram illustrated in fig. 2 only reflects a connection relationship, not a position relationship, between different components in the VR scene experience system. As can be seen from fig. 1 and fig. 2, in the present embodiment, the VR scene experience system 1 includes VR glasses 13, a first mechanical arm 11, a second mechanical arm 12, and a control device 14.

The VR glasses 13 are worn on the head of the user, and the main configuration is two lenses, which are included, and the lenses create different image depth perception in the local space based on different visual fields, so as to form a virtual reality visual field in the brain visual system of the user. The VR glasses 13 use a head-mounted display device to seal the vision and hearing of the user from the outside, and guide the user to generate a feeling of the user in the virtual environment, and the display principle is that the left and right eye screens respectively display images of the left and right eyes, and the human eyes generate a stereoscopic impression in the mind after acquiring the information with the difference. The VR glasses 13 can provide a virtual scene for the user, the virtual scene comprises one or more combinations of an entertainment scene, a sports scene, a treatment scene, a game scene, a social scene and a learning scene, and the user can select or customize the virtual scene according to the needs of the user.

The first mechanical arm 11 includes a base 111, a first joint 112, a second joint 113, and a third joint 114, and is used for assisting a user in completing movement in a three-dimensional space. The first mechanical arm 11 is at least a three-degree-of-freedom mechanical arm, that is, the first mechanical arm 11 can realize X movement, Y movement, and Z movement. Preferably, the first robot arm 11 has six degrees of freedom, that is, the first robot arm 11 can realize X movement, Y movement, Z movement, X rotation, Y rotation, and Z rotation. The first robot arm 11 utilizes a first joint 112, a second joint 113 and a third joint 114 to achieve telescopic and rotational movements, and the base 111 is used for fixing the first robot arm 11.

In a specific implementation process, the first mechanical arm 11 fixes a user at the end of the mechanical arm by using the third joint 11, and the first mechanical arm 11 drives the user to move in a three-dimensional space through stretching and rotating. By adjusting the speed and force of the first mechanical arm 11, the user can complete similar position changes in the virtual scene at similar speed, for example, the user can complete jogging, quick jumping, and the like. Furthermore, when the user performs an action, the first mechanical arm 11 assists the user to complete the action under the control of the control device 14, for example: when the user does not move in place due to insufficient strength, the first mechanical arm 11 can provide assistance for the user so that the user can smoothly complete the movement; or the first robot arm 11 can direct the user motion in the correct direction when the direction of the user motion deviates.

In an actual implementation process, on the premise of ensuring the safety of the user, the first mechanical arm 11 only contacts the user at the positions of the head, the back, the legs, the hands, and the like. Compare in traditional cladding formula VR equipment, the user is more nimble and comfortable at experience in-process.

The second arm 12 includes a base 121, a first joint 122, a second joint 123, a third joint 124, and a gripper 125. The first joint 122, the second joint 123 and the third joint 124 are used for assisting the hand claw 125 to move in a three-dimensional space, and the hand claw 125 can grab an object and send the object to a specified position under the control of the control device 14. Specifically, the gripper 125 selects a corresponding prop in the current scene to send to the hand of the user under the control of the control device 14, for example, to provide the user with an equipment prop in a game scene or provide the user with sports equipment in a sports scene. The second mechanical arm 12 is at least a three-degree-of-freedom mechanical arm, and preferably, the second mechanical arm 12 is a six-degree-of-freedom mechanical arm.

The control device 14 is connected in communication with the first mechanical arm 11 and the second mechanical arm 12, and is configured to control the first mechanical arm 11 and the second mechanical arm 12 to move in a three-dimensional space and perform corresponding actions. The motion includes an auxiliary motion of the first robot arm 11, a grasping motion of the second robot arm 12, and the like.

In an embodiment of the present invention, the VR scene experience system 1 further includes a slide rail assembly 15, where the slide rail assembly 15 is connected to the first mechanical arm 11 and the second mechanical arm 12, and is communicatively connected to the control device 14, so as to assist the three-dimensional space movement of the first mechanical arm 11 and the second mechanical arm 12.

In an embodiment of the present invention, the slide rail assembly 15 includes: the first slide rail 151 is arranged at the bottom of the first mechanical arm 11 and used for assisting the first mechanical arm 11 to move left and right along the first slide rail 151; a second slide rail 152 disposed at the bottom of the second mechanical arm 12 for assisting the second mechanical arm 12 to move left and right along the second slide rail 152; and a third slide rail 153, disposed at the bottom of the first slide rail 151 and the second slide rail 152, for assisting the first slide rail 151 or/and the second slide rail 152 to move back and forth along the third slide rail.

Specifically, the first mechanical arm 11 is connected to the first slide rail 151 and can move left and right along the first slide rail 151; the first slide rail 151 is connected to the third slide rail 153, and can move back and forth along the third slide rail 153. The first mechanical arm 11 can reach any point in the whole sliding rail range through the movement of the first mechanical arm on the first sliding rail 151 and the movement of the first sliding rail 151 on the third sliding rail 153, and the movement range in the horizontal direction is widened. By combining the extension and rotation of the first mechanical arm 11, the movement of the first mechanical arm 11 on the first slide rail 151, and the movement of the first slide rail 151 on the third slide rail 153, a user can realize three-dimensional movement within the range of the slide rail assembly 15, and when the position of the user changes in a virtual scene, the body of the user can complete similar position changes at the same speed, so that the coordination of the physical feeling and the visual feeling of the user is ensured, and the spatial experience of the user is improved.

The second mechanical arm 12 is connected to the second slide rail 152 and can move left and right along the second slide rail 152; the second slide rail 152 is connected to the third slide rail 153, and can move back and forth along the third slide rail 153. The second robot arm 12 can reach any point within the entire slide rail assembly 15 by moving itself on the second slide rail 152 and moving the second slide rail 152 on the third slide rail 153. The second robotic arm 12 can reach under or behind the user as necessary to deliver a physical prop to a designated location.

In an embodiment of the invention, the VR scene experience system further includes a ground feedback board 16; the ground feedback board 16 is disposed under the foot of the human body, and is connected to the control device 14 in a communication manner, and includes a plurality of irregular columns 161 for enhancing the tactile sensation of the sole of the foot. Please refer to fig. 3, which is a schematic structural diagram of the ground feedback plate 16 according to an embodiment of the present invention. As can be seen, the floor feedback plate 16 is comprised of a support plate 162 and a plurality of irregular cylinders 161. The ground feedback plate 16 is disposed under the feet of the user for enhancing the tactile sensation of the soles of the feet of the user. Specifically, the supporting plate 162 mainly plays a supporting role, so that the user can clearly feel that the user steps on the actual object under the foot; each of the irregular cylinders 161 is moved upward or downward under the control of the control means 14, and the tactile sensation in a local range of the sole of the foot of the user can be enhanced. For example, when a user steps on an object in a virtual scene, the irregular cylinders 161 at the corresponding positions move upwards, and the rest irregular cylinders 161 are kept still, so that the corresponding positions under the feet of the user can generate a squeezing feeling, and the simulation of stepping on the object by the soles is realized; when the user is in an uphill slope in the virtual scene, the irregular cylinders are sequentially lowered from the positions in front of feet to the positions behind the feet, so that the user feels that the body of the user leans backwards, and the uphill slope is simulated. Preferably, the irregular cylinder 161 may be implemented by using an inflatable balloon, which has a shape of a cylinder or a square column.

In an embodiment of the invention, the VR scene experience system further includes a support arm; the support arm is connected with the control device and is used for assisting the human body to move and/or providing tactile sensation for the human body. In this embodiment, the support arm contacts with a corresponding part of the body of the user, so as to assist the specific part of the user to complete a corresponding action, and protect the parts from being injured by muscle strain. Unlike the conventional wrapped VR experience device that uses an exoskeleton or the like, in this embodiment, the first mechanical arm and the support arm are matched to contact with the user only at a specific position, so that the assistance to the user is more accurate. Meanwhile, other parts of the body of the user are not bound by the exoskeleton, so that the user can act more flexibly and comfortably in the experience process, and the feeling is more real. In addition, the arm is provided with a sense simulation unit, which can provide similar stimulation for the user when the user is stimulated at a specific position in the virtual scene, such as: the user can be stimulated to generate pain when falling down, and the tactile stimulation is provided for the user when the user contacts an object.

In one embodiment of the present invention, the arms 17 include one or more of a head arm 171, a hand arm 172, a foot arm 173, a waist arm 174, and a hip arm. The head support arm 171 is in contact with the head of the user for fixing the head of the user and simulating a corresponding tactile sensation; the hand support arm 172 is in contact with the hand of the user and is used for fixing the hand of the user and simulating corresponding tactile sensation; the foot support arm 173 contacts the foot of the user for fixing the foot of the user and simulating a corresponding tactile sensation; the waist support arm 174 is in contact with the waist of the user and is used for fixing the waist of the user and simulating corresponding tactile feeling; the buttock support arm is in contact with the user's buttock for fixing the user's buttock and simulating a corresponding tactile sensation.

In an embodiment of the invention, the VR glasses are communicatively connected to the control device through a wireless communication manner. Preferably, the VR glasses and the control device communicate wirelessly, for example, through bluetooth, wiFi, 3G, 4G or Zigbee communication connection.

The open-loop control mode refers to that the first mechanical arm, the second mechanical arm and the VR glasses preset actions or scenes taken at each time point, and the first mechanical arm, the second mechanical arm and the VR glasses work independently according to preset programs without interaction. After the control device completes the presetting, continuous control is not needed, for example: at a certain moment, the VR glasses present an object for a user, the first mechanical arm assists the user to complete a hand stretching action at the same moment, the second mechanical arm sends an entity prop to the hand of the user, and the three actions are preset. The open-loop control mode has the advantages of simple operation, strong controllability, no need of a complex control system and the defects of preset actions, weak participation sense of users and relatively poor experience.

When the control device adopts the closed-loop control mode, the control device continuously controls the first mechanical arm, the second mechanical arm and the VR glasses. The control device controls the VR glasses to provide a virtual scene for a user, then controls the first mechanical arm to assist the user to complete corresponding actions according to the current virtual scene and the reaction and action of the user, and controls the second mechanical arm to provide corresponding props for the user according to the actions of the user. For example: at a certain moment, the VR glasses present an object to the user, and the user can choose to reach for grasping or directly walk through: when a user selects to stretch hands to grab, the control device controls the first mechanical arm to assist the user in completing a hand stretching action, and the control device controls the second mechanical arm to send a tool to the hand of the user; when the user selects to walk directly, the control device controls the first mechanical arm to assist the user in completing walking actions and controls the VR glasses to present corresponding scenes. By adopting a closed-loop control mode, the control device can make corresponding decisions according to the actions of the user and the contents presented by the VR glasses, and send decision information to the VR glasses, the first mechanical arm, the second mechanical arm and the ground feedback plate; the VR glasses, the first mechanical arm, the second mechanical arm and the ground feedback plate make corresponding actions according to the received decision information and feed back the corresponding actions to the control device. The closed-loop control mode has the advantages that different components interact with each other to enable a scene to be closer to reality, and user experience and participation sense are stronger; the disadvantage is that the closed-loop control requires a high degree of effort on the control device.

In an embodiment of the present invention, the VR scene experience system further includes: the sound effect device is connected with the control device in a communication mode and is used for providing sound corresponding to the virtual scene; the blowing device is in communication connection with the control device and is used for simulating the air flow in the virtual scene; and the moisture spraying device is in communication connection with the control device and is used for simulating the humidity change in the virtual scene.

To sum up, the VR scene experience system comprises a first mechanical arm and a sliding rail assembly, so that the moving range of a user in a three-dimensional space is expanded, and the spatial experience of the user is enhanced; the VR scene experience system comprises a second mechanical arm, the second mechanical arm can provide an entity prop for a user, and the VR scene experience system comprises a ground feedback plate and a support arm, so that the touch sense of the user is enhanced; the VR scene experience system assists a user in moving through the first mechanical arm and the support arm, so that the user can complete a plurality of actions which cannot be completed in reality; the VR scene experience system realizes fine control of the whole system through the control device, so that all parts are coordinated with each other. Compared with the traditional VR scene experience system, the VR scene experience system only contacts with the body of the user at a specific part, and the assistance to the user is more precise, so that the action of the user is more flexible and comfortable. Therefore, the invention effectively overcomes various defects in the prior art and has high industrial utilization value.

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
