Hybrid Object and Screen Stabilized Visualization Techniques for an AR Assembly Support System

This study proposes and evaluates the effectiveness of hybrid object and screen stabilized visualization techniques for an assembly support system using augmented reality (AR). Object stabilized visualization techniques are frequently used in AR-based assembly support systems but are not always available for the types of tasks, large sizes of assembled models, and narrow field-of-view head mounted displays (HMDs) examined in this paper. Based on a pilot study that investigated the best display locations and content sizes for displaying guidance information on an HMD screen, we propose two hybrid object and screen stabilized visualization modes, and then evaluate the two modes with an object stabilized visualization mode that we studied in the previous works (the side-by-side mode). Our experimental results indicate that the hybrid mode showing target assembly objects at a fixed position on the HMD screen with object stabilized orientation yields the best performance and subjective rating.
