The scope of the utility model protection.
In order that the motion realization of user of the VR motion seats with wearing VR glasses 5 is synchronous, as shown in figure 1, the present embodiment
It is related to a kind of virtual reality system, including motion seat, VR glasses 5 and at least one attitude transducer;Motion seat includes seat
Chair, motion platform 4 and control unit 1, wherein motion platform 4 include upper mounting plate, lower platform, electric cylinders 4-1 and motion hinge, wherein
Electric cylinders 4-1 both ends are connected to upper mounting plate and lower platform by motion hinge respectively;At least one attitude transducer comprises at least
For the first attitude transducer and/or the second attitude transducer being connected with control unit 1;The motion seat is logical with VR glasses 5
Letter, and control unit 1 controls electric cylinders 4-1 actions after the attitude angle data of at least one attitude transducer feedback is received.
Specifically, user is sitting on the seat of motion seat, and the motion seat is supported by motion platform and according to electric cylinders 4-1
Expansion link flexible and move, for the attitude angle data of precise acquisition user, in the present embodiment, head pose sensor
2 are arranged on the crown of user, and shoulder attitude transducer 3 is arranged on above the shoulder of user, in order to keep each biography
The stability of sensor, head pose sensor 2 and shoulder attitude transducer 3 can pass through sensor stand(It is not shown)It is arranged on
On user's body., it is necessary to make body keep rectifying posture, so as to head before VR glasses 5 start game in user's wearing
Attitude transducer 2 and shoulder attitude transducer 3 are resetted, and using this state as original state or initial position.
