An instruction method of 3D task motion with stereoscopic video see-through display and its application to pouring task

Research of manufacturing support using augmented reality has been advanced. It is a technology to present the appropriate work instructions to a worker through a display device. By using the technology, the worker can perform a task that requires skill, even if a worker is not an expert. Previously, in this technology, static work instructions, such as the component mounting position and assembly procedure have been mainly presented. However, the presentations of dynamic work instructions are required in some manufacturing tasks. For example, some tasks are required the operations of the work tools including the translation and rotation in three dimensions. If the dynamic work instructions of such a complicated task can be presented, it will be possible to support more varieties of manufacturing tasks. In order to realize it, an instruction method of the three-dimensional task motion of the work tool is examined using a stereoscopic video see-through display in this paper. Then, in order to evaluate the instruction method, the pouring task in casting process is selected as an example application. Furthermore, the results of evaluation experiments are reported.
