Information transmission system to transmit work instruction information

An information transmission system for transmitting work instruction information from a work instructor to a worker, comprising:

• an image pickup device fastened to the head of said worker, and picking up an image of an object to be worked on within a range including at least said worker's field of view,
• a first transmission device transmitting video information of said object generated by said image pickup device to said work instructor side,
• a first display device displaying said video information transmitted from said first transmission device to said work instructor,
• a position information input device entering pointing position information with respect to said object by said work instructor based on said video information displayed on said first display device,
• a second transmission device transmitting said pointing position information input by said position information input device to said worker side,
• a moving distance detection device detecting a spatial moving distance of said worker's head during a time starting from an image pickup time by the image pickup device up to the time the pointing position information reaches said worker side,
• a correction device correcting said pointing position information obtained at said worker side corresponding to said spatial moving distance of the head detected by said moving distance detection device,
• an information combining device combining said video information of said object generated by said image pickup device and marker video information according to said pointing position information corrected by said correction device, and
• a second display device displaying information combined by said information combine device to said worker.
