Interface apparatus and hang gliding experience system
An interface apparatus for providing a user with a hang gliding experience in a virtual space includes: a control bar which the user is to grip; a tilt mechanism which supports the control bar from above such that the control bar is tiltable; a force sensor that is provided to the tilt mechanism and that detects a force and a moment which are applied from the user to the control bar; and an input and output section that provides a signal indicative of the force and the moment to a simulation apparatus configured to generate the virtual space and that acquires, from the simulation apparatus, a control signal for controlling the tilt mechanism so as to tilt the control bar.
1 . An interface apparatus comprising:
a control bar which a user is to grip;
a tilt mechanism which supports the control bar from above such that the control bar is tiltable, the tilt mechanism being fixed to a ceiling of a room in which the interface apparatus is installed;
a force sensor that is provided to the tilt mechanism and that detects a force and a moment which are applied from the user to the control bar;
a harness that supports a trunk and legs of the user such that the trunk and the legs of the user extend horizontally, the harness being hung from the tilt mechanism or the ceiling; and
an input and output section that provides a signal indicative of the force and the moment to a simulation apparatus configured to generate a virtual space and that acquires, from the simulation apparatus, a control signal for controlling the tilt mechanism so as to tilt the control bar,
the tilt mechanism including:
a base fixed to the ceiling;
a plurality of movable links having upper end portions each coupled to a peripheral portion of the base; and
a tilt member having an upper surface a peripheral portion of which is coupled to each of lower end portions of the plurality of movable links,
the control bar including:
a pair of uprights that have upper end portions fixed to the tilt member and that extend downward; and
a base bar having left and right end portions fixed to respective lower end portions of the pair of uprights,
the force sensor being attached to the base,
the force sensor detecting strain that occurs in the base when the user attempts to move the base bar,
the force and the moment being calculated on a basis of the strain.
2 . The interface apparatus according to claim 1 , wherein the tilt mechanism is a parallel link mechanism.
3 . A hang gliding experience system comprising:
the interface apparatus according to claim 1 ; and
the simulation apparatus,
the simulation apparatus determining a tilt direction of the control bar and a tilt angle of the control bar in view of a state of an atmosphere in the virtual space and a posture of the user which posture has been specified by the force and the moment.
4 . The hang gliding experience system according to claim 3 , further comprising a head mounted display which displays an image that represents the virtual space and that has been acquired from the simulation apparatus.
