“…Lilija [14] and Gruenefeld [15] both researched applications of occlusion visualization. Lilija [14] displayed the occluded information to the user using multiple methods and found that users had a preference towards an appropriate point of view and view stability. The see-through view presented in their work is the most applicable to the system presented in our paper, with the remaining methods relying on the static scenarios presented by Lilija.…”

We present an approach for visualizing mobile robots through an Augmented Reality headset when there is no line-of-sight visibility between the robot and the human. Three elements are visualized in Augmented Reality: 1) Robot's 3D model to indicate its position, 2) An arrow emanating from the robot to indicate its planned movement direction, and 3) A 2D grid to represent the ground plane. We conduct a user study with 18 participants, in which each participant are asked to retrieve objects, one at a time, from stations at the two sides of a T-junction at the end of a hallway where a mobile robot is roaming. The results show that visualizations improved the perceived safety and efficiency of the task and led to participants being more comfortable with the robot within their personal spaces. Furthermore, visualizing the motion intent in addition to the robot model was found to be more effective than visualizing the robot model alone. The proposed system can improve the safety of automated warehouses by increasing the visibility and predictability of robots.

“…But the vibrotactile suits could decrease the simulation fidelity because it could interfere with users' movement. Visual-based approaches use visual cues [41] or improved display interface [23] to enhance users' spatial awareness in virtual environments. This approach only relies on basic VR devices and can work with mark-less body tracking system [46,48].…”

“…Inspired by this, we proposed to integrate multiple perspectives in the VR interface to provide stronger spatial awareness while ensuring the natural interaction. Multiple perspectives integration has been widely studied to improve user's navigation [28], collaboration [33], and manipulation performance [23]. However, no previous research studied it for assemblability assessment tasks in the complex environments.…”

Multiple perspectives integration for virtual reality-aided assemblability assessment in complex virtual assembly environment

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 useful enough to support assemblability assessment in complex virtual assembly environments. In this paper, we proposed the multi-perspectives interface (MPI) which integrates the 1PP and the third-person perspective (3PP) using handheld World-in-Miniature (WIM). The MPI allows users to simulate the assembly operations in a natural manner similar to 1PP, while providing users with an overview of the assembly status through the WIM to assess the assemblability with superior spatial awareness. Two studies were included in this paper. The first study tested MPI in a general interaction task, which reveals stronger spatial awareness in MPI than in 1PP without the cost of losing natural interaction. The second study tested the performance, usability, and workload of MPI in an assemblability assessment task. The results show the advantages of MPI in the reachability evaluation. The contribution of this paper is exploring a novel interface for VR-aided assembly design and evaluation system.

“…To solve the problems mentioned above, a straightforward thought is to integrate the 1PP and 3PP to reap the advantages of the two perspectives. Technologies of multiple perspectives integration have been extensively studied to improve user's navigation [29], collaboration [34], and manipulation performance [23]. World-in-miniature (WIM), which can integrate the 1PP and 3PP simultaneously into a single interface with considerable interaction performance [14], is one of the most sound integration technologies.…”

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 the multi-perspectives interface (MPI) which integrates the 1PP and the third-person perspective (3PP) using the handheld world-in-miniature (WIM). The MPI allows users to simulate the assembly operations in a natural manner similar to 1PP, while providing users with an overview of the assembly status through the WIM to assess the assemblability with superior spatial awareness. Two studies were conducted to test the performance of the proposed MPI. The first study tested user’s interaction performance in MPI using a common interaction task, which reveals stronger spatial awareness in MPI than in 1PP without the cost of losing natural interaction. Based on the results of the first study, the second study tested the performance, usability, and workload of MPI in an assemblability assessment task. The results show the advantages of MPI in the reachability evaluation in the narrow spaces. The main contribution of this paper is improving the interface and user-interface interaction in VR-aided assembly assessment system to improve user’s interaction performance and assessment ability in narrow assembly spaces.
