Abstract

A remote operation system includes an edge device that contacts a target, a motion operation transmission device that receives an operator operation for operating the edge device and outputs motion transmission information to the edge device, and a visual presentation device that displays an image of the target and the edge device. The edge device-includes a haptic sensing device that detects a haptic sensation to the target, a haptic optical converter that converts the haptic sensation detected by the haptic sensing device into a light intensity signal specifying the intensity of light, and a light intensity-controlled light emitter that emits light of an intensity corresponding to the light intensity signal.
