LMPB multi-function virtual scene treadmill

Every object in virtual scene has shape and appearance which must be provided in model files of geometric model stored in virtual scene, Virtual modeling technique three common indexinteractive display capability, interactive manipulation capability easy virtual scene configuration capability as to the demand of virtual objectmodel.Open GL could easily finish models transformation,colouring,illumination,texture adjustment,interactive operation and anmination but it only can provide basic mould making function of geometrical elements which makes complicate modeling difficult. Therefore,after making complicate model in Creator modeling tool,we usually control and transform photos in Open GL.
After system integration of virtual scene and running machine system,see photo No.5, through auto stereoscopic displays, the scene will automatically  roam along with motion of exerciser. photo No.6 as if be personally on the scene, letting the exerciser completely immersing in self-chosen virtual scene which not only exercise body but also enhance entertainment effects.

(4) sports data retrive technology
In virtual running machine system, for the purpose of interaction between man and virtual scenes, it needs extract sports parameters working in spors equipments(running machine)and enters them into computer to function in virtual scenes.in virtual running machine, sports data is mainly tansfered to computer through senese transmitter and data collection card such as date collection of  angles of running posture and heart rate and etc. angle-degree sense tranmitter transform users feet forcing angles into electrical signals and then transfers these signals to data collection card;  have a real time collecton of users heart rate through heat rate meter and also can adopt presently available heat rate data collection system.
4.Scene Function Features
The virtual scene of Lanmei multi-function virtual scene running machine is divided into five parts:sports ground scene,country footpath,seaside,city pedestrian street, mountain scenery and etc.

1.Product Introduction
With the advance of science and technology, the pace of life obviously is speeding up which directly leads many people to physical sub-healthy state, as a result, the desire for being healthy is unprecedentedly surging up.due to the space limitation, the majoriity of people do body exercise in diferent kinds of fitness centres which inspire the arrival of varied indoor exercise machines such as indoor running machine and indoor bicycle and etc. these fitness centers and exercise machines haves improved peopelehealth status to some degree,but they could not satisfy the increaaing demand of scientific and happy body-exercise. Peopele are expecting an body-exercise machine which can effectively combines indoor fitness functions and outdoor nature environment.
Lanmei multi-function virtual-reality scene running machine ----lanmei company has honour to present to you.
Lanmei LMPB multi-function virtual scene running machine is the first class of sports products which adopts contemporary cutting-edge technology such as virtual-reality simulation, radio communication,multi-media and etc, it is the condensation of wisdom and sweat of fifty research and development staff in lanmeiVR at home and  abroad, including many design and invention patents.
Virtual-reality(VR) technology adopts computer simulation scene of human and nature to replace the real world environment which give  user feeing of be in real outdoor environment in running exercise. After an extensive study about the system of traditional running machine,the research staff in lanmei company design an innovative multi-function running machine which lets people have a feeling of doing body exercise in a real oudoor scene through computer-made virtual scenes.
by using of multi-channel interactive technique such as VR and stereo display technologies and etc.
The perfect combination of VR technology and fitness machine has completely changed peopelelife style, the running machine system using VR technology designed by lanmei company will be to change peopleexercise style and also will play an increasing important role in the combination process with sports technology
2.System Design
VR technology assist in the researh and development of multi-kinds of fitness machines. Fitness machine using VR technology brings people a feeling of be in outdoor environment in exercise which meet the deamnds of feeling outdoor environment while doing indoor fitness exercise.
VR technology is the real-time domenstration of human-senstaion world simulation, here the wolrd not only can be the reoccuring of some certain real- world scenes, but also could be pure fictional virtual scenes,the user can communicate with the world through multi-channels such as  the senses of vision,hearing,touch and etc and has a feeing be personally on the real scenes
VR fitness machine lets exercisers immerse in kinds of virtual sports scenes and have a impact feeling brought by VR technology, furthermore,users could organise own body-exercise teams through network platforms and hold kinds of body- exercise competition matches to feel the thril of body building. In recent years, prime research aspects have been focusing on qualitative simulation, distributed interactive simulation, visual simulation,multimedia simulation,VR-based simulation and etc different from previous four kinds of simulation methods,VR-based simulation mainly focuses on multi-channel sensing capability, interaction and immersion which provides exerciser an effective and brand new training method.
Based on present research and development status of VR technology and fitness machine combination, Lanmei company adopts VR technology to do research and design work as to traditional running machine system.
3.Research and Design of Multi-Funtion Running Machine System
Traditional running machine system belongs to common heath machine product, there are two purpose for using running machine: weight lose and body building. virtual scenes could have multi-conditions(playground, road, suburb and etc) choice and multi-level adjustment mode.
For different body-exercise groups,lanmei multi-function running machine system using VR technology takes different channels of vision sense,sound sense,human body sensation and etc into consideration while meeting the body exercise demand of users.
(1)modeling and drawing technology
Modeling and real time drawing is the most basic in the running machine system based on VR technology,in aspects of model precise degree and drawing speed, not only need to guarantee display quality but also not to bring discomfortableness to user in exercise process. This system developed by VC++ and OpenGL, having fuctions of model anmination  menu selection, auto show automap, route roaming,marine plant generation geography forming and use level of detail(LOD) technology and etc to optimize render speed.
(2) real time display technology
After making complicate model  in the modeling tools such as Creator ,3ds Max and etc,secondly converts file format and load into system software, then make to reach enough frame rate(above 30 frame rate per second) meet real time smooth interaction between user and machine through data optimization.
(3) stereoscopic display technology
Stereoscopic Display technology Is the key aspect of VR technology, use complementary colorstereoscopic Display model(reddish green and blue display).
