1. A work support system comprising:
a display device;
one or more sensor units that measure a motion of a user; and
an arithmetic apparatus that displays a 3D work-target object in a 3D coordinate space on the display device and receives a motion signal that is a signal representing a motion measured by any one of the sensor units,
when receiving the motion signal, the arithmetic apparatus:
(A) identifying the measured motion based on the motion signal by:
(a1) identifying a type of the measured motion;
(a2) identifying a type of movement corresponding to the identified type of motion;
(a3) when the identified type of movement is a switching movement of switching between a spatial shift and a work movement, switching a current movement from the spatial shift to the work movement or from the work movement to the spatial shift;
(a4) when the identified type of movement is not the switching movement and the current movement is the spatial shift, identifying that the measured motion is a motion regarding the spatial shift; and
(a5) when the identified type of movement is not the switching movement and the current movement is the work movement, identifying that the measured motion is a motion regarding the work movement;
(B) when the identified motion is a motion regarding the spatial shift that is a shift of a viewpoint in the 3D coordinate space of the user, wherein the motion regarding the spatial shift is one of a hand motion or a non-hand motion, shifting the viewpoint in the 3D coordinate space of the user in accordance with the identified motion; and
(C) when the identified motion is a hand motion regarding the work movement with respect to a work target, outputting output information including information representing the work movement in accordance with the identified motion,
wherein the sensor units include a remote controller, and
wherein the type of motion corresponding to the switching movement is a predetermined motion using the remote controller.
