“…Suggested improvements: Several participants reported difculties in determining the distance between the avatar and interactive objects, such as the cubes they had to pick up, as well as bars they had to jump to and grab. This is in line with prior research on how a 3rd person perspective can make precise interactions more difcult [2,30]. More research is needed to determine the best ways to mitigate this, e.g., by switching to 1PP for some interactions like in [32], or designing lighting and shadows in a way that gives extra depth cues.…”

“…Although having a 3rd person, bird's eye view of an environment provides spatial awareness superior to 1PP, it should be noted that 3PP sets some limits on interaction: interaction with virtual objects is less accurate, e.g., when catching or defecting projectiles [2,30]. On the other hand, the problems can be mitigated by techniques such as predictive visualization of movement trajectories, or sliding the avatar towards a target while punching [2]. We implement the latter in our 3PP-R prototype.…”

“…• Exaggerated jumping between platforms (Figure 5C, video at 01:12). • Grabbing and dropping objects, with target acquisition logic that counteracts the reduced interaction accuracy in 3PP compared to 1PP (e.g., [2,30]). Objects are pulled to the user's hand when the user presses the grab button.…”

Figure 1: 3PP-R allows the user to interact in 3rd-Person Perspective (3PP) using natural movements, including body rotation without losing sight of the avatar. A virtual display such as a 3D miniature world model hovers in air in front of the user, showing a 3rd-person avatar. When the user turns, the display orbits around the user but does not rotate except for the avatar. From the user's perspective, the display appears fxed in the feld of vision, and the world rotates around the avatar.

“…The most obvious drawback of 1PP is that users cannot obtain the information out of the FOV of 1PP. The drawbacks of 3PP are the inconsistency between the viewpoint of 3PP and human's natural perspective, resulting in the reduction of the sense of self-location [15] and interaction performance [2,15]. Alonso et al [2] studied the 3PP camera positions on interaction difficulty and found that the interaction performance increases with the 3PP camera getting closer to users' head.…”

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.

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.
