Training support for pouring task in casting process using stereoscopic video see-through display - Presentation of molten metal flow simulation based on captured task motion

The work support technology using augmented reality has been researched in the field of manufacturing. It is the technology that can present appropriate instructions to a worker. Thereby, the worker performs a task requiring an advanced skill even if she/he is not an expert. In this technology, most of work instructions are presented while the worker is working. However, there are many manufacturing tasks that is difficult to be retried when it fails. In order to deal with such tasks, a training support technology that a worker can train tasks beforehand using augmented reality is proposed. This technology can present simulated task results according to the motion of the worker. As a simulation result, for example, the worker can see internal state of the work object. And she/he can train as many times as she/he wants. Therefore, her/his skills can be improved through trial and error. In this paper, a concept of task training support technology is introduced. To realize the concept, the pouring task in casting process is selected as a target task and the prototype system is constructed. Then, the evaluation results of pouring task training using the prototype system are reported.
