Expert manual workers in factories assemble more efficiently than novices because their movements are optimized for the tasks. In this paper, we present an approach to projecting the hand movements of experts at real size, and real speed and onto real objects in order to match the manual work movements of novices to those of experts. We prototyped a projector-camera system, which projects the virtual hands of experts. We conducted a user study in which users worked after watching experts work under two conditions: using a display and using our prototype system. The results show our prototype users worked more precisely and felt the tasks were easier. User ratings also show our prototype users watched videos of experts more fixedly, memorized them more clearly and distinctly tried to work in the same way shown in the videos as compared with display users.
