Multiple perspectives integration for virtual reality-aided assemblability assessment in narrow assembly spaces

Abstract Virtual reality (VR) has been proved as a promising tool for industrial design, but the traditional VR interface of first-person perspective (1PP) is not efficient to support assemblability assessment in narrow assembly spaces. In this paper, we proposed multi-perspectives (MPI) which integrates 1PP and third-person (3PP) using handheld world-in-miniature (WIM). The MPI allows users simulate operations natural manner similar 1PP, while providing with an overview status through WIM assess superior spatial awareness. Two studies were conducted test performance MPI. first study tested user’s interaction common task, reveals stronger awareness than without cost losing interaction. Based on results study, second performance, usability, workload task. show advantages reachability evaluation main contribution paper improving user-interface VR-aided system improve ability
