Abstract
A simple universal walking platform is applied to a virtual reality system. The system combines human engineering and the virtual reality experiment requirements of environment design. In the process of bearing the walking operation of a single person, the person is allowed to freely step forward and walk in all directions, and through specially-designed side tread faces, the motion is limited in a central area through the self weight of the person. A bowl container shape is overall adopted, the state of a big base plate and a large slope is achieved, the platform comprises the base plate in the center and the side tread faces on the periphery, the base plate is the central area of the walking platform, and a rough plane is adopted. The side tread faces on the periphery are deigned to be in slope types, and smooth planes are adopted. Any motor devices are not adopted by the simple universal walking platform, the specially-designed side tread faces of the bowl-shaped platform and different set surface friction coefficients are fully utilized, and movement compensation is achieved through the gravity of the person. The simple universal walking platform has the advantages of being quiet, small in occupied area, low in manufacturing cost, easy to maintain and suitable for popularization and using.
Description
Technical field
The utility model relates to a kind of sports apparatus, is applied to virtual reality system.
Background technology
All disclose universal walking carrying platform in following system, but be applied to virtual reality system, they have shortcoming separately.
1) iPlane (1996) is all direction walking platform made from traditional treadmill principle the earliest, and it lays fixture in user's loins, makes it walk and run in the enterprising every trade of universal walking platform.The stopping means of loins can allow the manipulator not feel well, and walking is had to certain interference, and when operation noise larger.。
2) CyberWalk (2011) subsidized by European Union, mounted motor in platform is installed video camera above platform, with video camera, reads manipulator's behavior, and the direction to control motor makes the manipulator get back to the platform center in real time.Each 6 meters of whole equipment length and width, wherein be 4.5 meters for the scope of walking and take advantage of 4.5 meters, weighs 9 tons.Equipment has a large amount of electromechanical assemblies, and cost is high, difficultly safeguard, have noise, place demand large, more difficult popularization.
3) CyberCarpet (2011) adopts equally video camera and combines containing motor platform, and the regular hexagon that the walking scope of platform is 0.8 meter of a diameter has been installed and surpassed 4000 beads, and the restriction manipulator can't the too fast or excessive movement of step-length.Equally, equipment has a large amount of electromechanical assemblies, and cost is high, difficulty is safeguarded, noise, more difficult popularization are arranged.
The utility model content
The utility model purpose is to overcome the deficiencies in the prior art, a kind of simple universal walking platform that is applied to virtual reality system is disclosed, this platform is in conjunction with ergonomics and the requirement of Environment Design class simulated reality experiment, in the process of the single walking behavior of carrying, both allowed it freely to take a step to walk about to all directions, again by specially designed side direction tread, the gravity that utilizes people self by this movement limit in central area.
For achieving the above object, the technical scheme that the utility model provides is:
A kind of simple universal walking platform, is characterized in that, the whole bowl that adopts is container-like, is the form on large slope, little chassis, and it comprises that the chassis at center and the side direction of surrounding trample face, the central area that described chassis be this walking platform, employing Rough Horizontal Plane; The side direction of described surrounding is trampled face and is designed to domatic form, adopts smooth flat.
Specifically, described walking platform adopts multi-layer sheet to process.
Further the optimisation technique scheme, stable for keeping it, in the neighboring of bowl container, increases gripper shoe.
Further optimisation technique scheme, its inner surface is used the blacking of spraying paint, and the mode that is coated with essential oil of being waxed on the inner surface slope increases smoothness.
Innovative point and beneficial effect: the external universal walking carrying platform of existing several moneys has all adopted a large amount of electromechanical equipments, and they offset people's the motion of walking behavior in world coordinate system on one's own initiative by real-time action recognition and dynamo-electric compensating motion.And the utility model does not adopt any electric machine, utilize the side direction of bowl-shape platform particular design to trample face fully, and the setting of different skin-friction coefficients, the gravity of employment is realized motion compensation.Be characterized in, quiet, take up an area little, cost is low, easy care, be suitable for promoting the use of.
The accompanying drawing explanation
The axle of the walking platform that Fig. 1 is the utility model omnibearing ambulation is looked schematic diagram.
The schematic top plan view of the walking platform that Fig. 2 is the utility model omnibearing ambulation.
Description of symbols: the chassis at 1-center, the side direction of 2-surrounding is trampled face, the 3-gripper shoe.
The specific embodiment
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further.
The utility model adopts bowl container-like for supporting user's omnibearing ambulation behavior, guarantees that the user can keep absolute position constant in walking platform, and relative position changes, and realizes being similar to the effect of universal treadmill.Relevant knowledge use ergonomics in concrete research in, study people's walking behavior attitude by experiment and data analysis repeatedly, obtain the attitude geometry feature of human locomotion behavior, thereby further obtain the geometric format of walking platform and step face and basic walking model.Final size, the moulding of determining the walking platform of supporting omnibearing ambulation.
The research discovery, in real environment, the movement that can produce center of gravity when carrying out the walking behavior.In bowl, walking must be handled in walking process the adverse effect that gravity motion causes well, and the slope design of walking platform has been proposed to very high requirement.The gradient of walking platform is crossed and suddenly can be caused the user can't carry out the Ambulatoria behavior in walking platform; The gradient of walking platform is crossed and slow can be caused the user to walk upslope finally to walk out walking platform.Simultaneously, due to forward lean, center of gravity reach, inappropriate walking platform slope can make the user lean forward to fall down, produce potential safety hazard.
That is, the design of walking platform at least meets following 3 requirements:
1) walking platform can meet the user and completes the walking behavior;
2) eliminate the adverse effect that the user produces because of gravity motion in gait processes;
3) guarantee the security that the user walks in walking platform.
Determine domatic form.The suitable user of this domatic form completes and lifts the walking action that leg advances, and in small scope, moves lifting leg advance and the advance tailheaviness of standing firm simultaneously, makes the user remain at the middle position of walking platform.
The slope user that wants help gets back to initial position, therefore the needs of its hypotenuse produce less frictional force, smooth as far as possible assurance involved party can walk and constantly fall after rise to central area on this is domatic.Simultaneously, for guaranteeing security in the process of walking of user and stationarity while standing, the central area of this walking platform must be coarse plane.
In Fig. 1, Fig. 2, walking platform adopts multi-layer sheet to process, and is the form on large slope, little chassis, stable for keeping it, at periphery, increases gripper shoe.Its inner surface is used the blacking of spraying paint, and the mode that is coated with essential oil of being waxed on the inner surface slope increases smoothness.
