A VIRTUAL REALITY OR GAME CONTROLLER USING HAPTIC WHEEL, A CONTROL METHOD, AND VIRTUAL REALITY SYSTEM HAVING THE SAME

摘要

The present invention relates to a VR or game controller using a haptic wheel and a control method thereof, and a VR system having the same, and more specifically, a VR or game controller using a haptic wheel, which forms the appearance of a VR or game controller. A haptic wheel installed in the housing, wherein some of the wheels are exposed so that a user can feel a sense of rotation in the VR controller housing; Based on MR fluid, which is connected to one end of the haptic wheel and is driven according to an event driving signal according to a virtual reality, graphic environment, or game environment-based service execution so that the user can feel a sense of rotation through the haptic wheel Or an ER fluid based actuator; An encoder fastened to the other end of the haptic wheel and sensing rotation of the haptic wheel; And controlling the operation of the actuator based on the MR fluid or ER fluid so that the user can feel the rotational sensation of the haptic wheel according to the execution of the virtual reality, graphic environment, or game environment-based service. It is characterized in that it includes a control unit. In addition, a control method of a VR or game controller using a haptic wheel according to a feature of the present invention is a control method of a VR or game controller using a haptic wheel, wherein (1) the controller is a virtual reality (VR) or graphic environment or a game environment. Detecting an execution event based on a virtual reality or graphic environment or a game environment for generating a sense of rotation according to the execution of the base service; (2) outputting, by the controller, an event driving signal corresponding to a virtual reality, graphic environment, or game environment-based execution event according to the execution of a virtual reality, graphic environment, or game environment-based service through step (1); And (3) the above step (2) so that the user can feel the sense of the haptic wheel partially exposed to the VR controller housing as a rotational sense by the actuator based on a magnetorheological fluid (MR fluid) or an electrorheological fluid (ER fluid). It is characterized in that it comprises a step of driving according to the event driving signal output from the control unit through. In addition, a VR system using a haptic wheel according to a feature of the present invention includes a VR or a game controller, and a VR device that performs a service based on a virtual reality or a graphic environment or a game environment in connection with the VR or game controller. It is characterized by its composition. According to a VR or game controller using a haptic wheel proposed in the present invention and a control method thereof, and a VR system having the same, some wheels so that a user can feel a sense of rotation in a VR controller housing that forms the exterior of a VR or game controller. The exposed haptic wheel and a magnetorheological fluid that is coupled with one end of the haptic wheel and driven according to an event driving signal according to the execution of a virtual reality, graphic environment, or game environment-based service so that the user can feel a sense of rotation through the haptic wheel (MR fluid)-based or electro-rheological fluid (ER fluid)-based actuators, encoders that are connected to the other end of the haptic wheel to sense the rotation of the haptic wheel, A virtual reality, graphic environment, or game environment-based service by including a control unit that controls the driving of an actuator based on MR fluid or ER fluid so that you can feel the rotational sensation of the haptic wheel. It is possible to make the user feel the sense of rotation according to the execution realistically with the sense of rotation of various speeds. In addition, according to a VR or game controller using a haptic wheel proposed in the present invention and a control method thereof, and a VR system equipped with the same, magnetic rheology coupled with a haptic wheel partially exposed to a VR controller housing that can be gripped by a user By allowing the MR fluid-based or ER fluid-based actuator to generate a rotational sensation in which the speed varies according to the frequency or voltage control signal, which is the drive control signal of the control unit, the user can use virtual reality or graphics. It is possible to experience and feel the rotational sensation of each situation of the environment or game environment-based service execution in a more realistic sense of vibration. In addition, according to a VR or game controller using a haptic wheel and a control method thereof proposed in the present invention, and a VR system equipped with the same, the situation according to the execution of a virtual reality or graphic environment or a game environment-based service through a VR or a game controller. By providing star haptics as a rotational sensation, users can experience a variety of rotational sensations that have a speed optimized for the execution of virtual reality, graphic environments, or game environment-based services. You can make it even better.
