Abstract
By a first camera fastened to the head of a worker at a remote working environment, an image of an object to be worked on is shot within a range including at least the worker's field of view. This image is transmitted to the work instructor side and displayed on a display device. The work instructor carries out a pointing indication movement with respect to the image of the object displayed on the display device. That movement is shot by a second camera and applied to an instruction information determination unit as video information. The instruction information determination unit generates pointing position information by the well-known gesture recognition process and transmits the information to the worker side. A marker according to the pointing position information transmitted from the work instructor side is overlapped on the image of the object shot by the first camera and displayed on the display of a head mount type display device fastened to the head of the worker. A particular region on the object is indicated by pointing to the worker. At the same time, the work procedure is explained by voice transmission from the work instructor.
