[POSTER] Hands-Free AR Work Support System Monitoring Work Progress with Point-cloud Data Processing

We present a hands-free AR work support system that provides work instructions to workers without interrupting normal work procedures. This system estimates the work progress by monitoring the status of work objects only on the basis of 3D data captured from a depth sensor mounted on a helmet, and it selects appropriate information to be displayed on a head-mounted display (HMD) on the basis of the estimated work progress. We describe a prototype of the proposed system and the results of primary experiments carried out to evaluate the accuracy and performance of the system.
