1. A direction presentation apparatus, comprising circuitry configured to:
calculate, using a first angle and a second angle, a second instructed force sense vector from a first instructed force sense vector,
wherein
the first angle is in an external coordinate system and represents an orientation of a camera that takes an image in front of a guided person,
the second angle is in the external coordinate system and represents an orientation of a force sense presentation device that presents the guided person with a predetermined direction,
the external coordinates refer to coordinates capable of representing north, south, east and west,
the second instructed force sense vector represents a vector representing a direction input to the force sense presentation device in a force sense presentation device coordinate system,
the first instructed force sense vector represents a vector corresponding to the predetermined direction in a camera coordinate system,
the force sense presentation device coordinates refer to coordinates capable of representing the direction with respect to the force sense presentation device's orientation, and
the camera coordinates refer to coordinates capable of representing the direction with respect to the camera's orientation.
