Contact determination device, control device, contact determination system, contact determination method, and non-transitory computer-readable recording medium

The present invention provides a contact determination device, control device, contact determination system, contact determination method, and contact determination program. This contact determination device acquires position information and/or posture information for a target person. Further, the state of movement of a part to be calculated in the body of the target person is calculated on the basis of acquired movement information and a body model relating to the shape of the body of the target person, said body model having been recorded in advance. Meanwhile, an electrical change is detected. Then, the contact determination device determines the state of contact between the target person and the object to be controlled on the basis of the detected electrical change and the state of movement of the part to be calculated in the body of the target person.
