ASSISTANCE SYSTEM, ASSISTANCE DEVICE, AND ASSISTED DEVICE

An assistance system includes an assisted device and an assistance device disposed to be separated from the assisted device. The assistance device includes a three-dimensional position detecting unit that three-dimensionally detects a hand position of an instructor, and a data transmission unit that transmits position information indicating the hand position detected by the three-dimensional position detecting unit. The assisted device includes a first image generation unit that generates a three-dimensional hand model image imitating a hand of the instructor based on the transmitted position information, and a first image combining unit that combines the hand model image with a captured image taken by the assisted device to generate a first combined image.
