When the controller receives an input signal from a smartphone, a computer, a tablet computer, a game console, a smart TV, a set-top box, a VR HMD, or the like input unit while a user is sitting on the couch body 1, corresponding actuation signals are transmitted to the two rotary body actuators 5 under control of the controller.
Therefore, each rotary body actuator 5 rotates the pulley of the rotary body 4 based on the rotational force of the actuation motor reduced into a predetermined reduction ratio by the reducer.
As the rotary body 4 rotates, the actuation connecting member 3 is unwound and wound to be changed in length, thereby transmitting the operational force to the couch body 1 through the rear binding band 22b.
In this case, the rotary body actuators 5 are spaced part from each other at the rear left and right sides of the couch body 1 and operate independently of each other, so that the actuation connecting members 3 can be different in length change and movement speed from each other, thereby implementing three-degree-of-freedom movements such as roll, pitch, yaw, heave, sway and surge movements.
The foregoing movements will be described in more detail with reference to
Further, the three-degree-of-freedom movements of the couch body 1 by the rotary body actuator 5 may implement various and realistic motions for movies or games, such as a motion based on continuous real-time information of the movie, the game or the like provided from the input unit to the controller, and motions and haptic responses prepared in advance and immediately performed by a motion controller when the decibel and pattern of a specific wavelength of a sound for the movie, the game, or the like provided from the input unit to the controller are normalized and the corresponding sound is output.
