Plate bending by line heating with interactive support through a monocular video see-through head mounted display

This paper describes the line heating experiment performed. Operating instructions are presented to a worker interactively through a monocular video see-through head mounted display (HMD). We are advancing research of interactive work support technology that unskilled person can perform a task that needs advanced skill by presenting the operating instructions through a wearable device. In order to present operating instructions, a monocular video see-through HMD was developed as a human interface. Thereby, operating instructions are superimposed on a work object and a processing point and a tool position posture, etc. are presented. Although this technology is applicable to various applications, here it is applied to the plate bending by line heating. The plate bending by line heating is a task that makes an iron plate transformation into a target shape by heating and cooling. It is well used for ship shell fabrication. In the experiment, a worker performs a line heating task according to the operating instructions presented by monocular video see-through HMD. As a comparison experiment, the torch fixed to the motorized linear slide was moved at fixed speed, and the iron plate was heated. In this paper, the comparison results of these experiments are reported.
