“…Therefore, it is possible that the HMD could give a better precision in both the exocentric distance and the position estimates in the frontal plane, if the HMD had been impeccably mounted and flawlessly fit the participant's eyes. Furthermore, to use VR displays for industrial applications, it was recommended that we used different calibration methods [10]. For example, Segura, Barandiaran, Moreno, Barandiaran and Flórez [10] developed an objective stereo display calibration method and got a more precise perception.…”

“…Stefanucci et al [9] argued that precise space visualization is critical in VR, which can enhance interaction performance and provide a virtual scene with satisfactory perceptual fidelity. Segura et al [10] also confirmed that the use of VR in industrial applications has been hindered because of visual discomfort and incorrect geometry perception. Accordingly, it is becoming increasingly difficult to overlook the investigation of visual space accuracy in VR.…”

Exocentric Distance Judgment and Accuracy of Head-Mounted and Stereoscopic Widescreen Displays in Frontal Planes

An experiment was done to explore the effects of two virtual display systems on the accuracy of exocentric distance judgment and position. Sixteen participants viewed animated virtual targets using either a head-mounted display (HMD) or a stereoscopic widescreen display (SWD). The virtual targets have been shown, one at a time, at three depth levels and with two corresponding exocentric distances and three target sizes at each target distance and, afterward, via pointing by holding a stick to estimate the exocentric distance and position of each target. The position data were collected using an OptiTrack motion capture system. The results showed that the accuracy of exocentric distance judgment was higher with the head-mounted displays than with the stereoscopic widescreen displays. In addition, higher position accuracy in the X-direction was obtained from the stereoscopic widescreen displays, whereas no significant difference was observed in position accuracy in the Y-direction. However, it is possible that the HMD could give better accuracy in both exocentric distance and position judgments in the frontal plane, if the HMD had been perfectly mounted and flawlessly fit the participant’s eyes. The result also revealed that exocentric distance judgment was significantly higher at the farthest target distances than at the nearest distance. Similarly, the position accuracy significantly increased as exocentric distance decreased. Moreover, engineers may allude to the findings as the evidence from the study suggests that the intermediate target distances might be fitting or ideal distances to design and structure 3D applications.

“…The environment visualized by the user changes if he/she changes his or her orientation, providing greater realism to the scene. VR has been applied in many fields, such as medicine [19], psychology [20], industry [21], or teaching [22]. A recent literature review [23] concluded that there is a lack of rigorous studies comparing the VR shop and other shopping contexts, so that VR should be compared with various content display media, such as images or other web-based 3D interfaces.…”

The emergence of new display technologies can change the perception of product design features and their assessment. Previous studies are limited to comparisons between a few technologies; the real product is considered only occasionally. This work compares the perceptions of 10 design features in two household products, shown by five display technologies (image rendering, 360° rotation, and augmented, immersive, and non-immersive virtual reality), and also with the real product. Results show that the 360° rotation provides the best perception for the most important features. However, the perception of aesthetic features is better achieved with i_VR. Other global results vary depending on the product. Finally, interaction with the real product shows a quite different perception for many features. The results contribute to the understanding of product perceptions influenced by different displays, comparing them with perceptions generated through real interaction. It is expected that the conclusions will be used to optimize the presentation of product features.
