Exploring the Effects of Scale and Color Differences on Users’ Perception for Everyday Mixed Reality (MR) Experience: Toward Comparative Analysis Using MR Devices

Abstract

With continued technological innovations in the fields of mixed reality (MR), wearable type MR devices, such as head-mounted display (HMD), have been released and are frequently used in various fields, such as entertainment, training, education, and shopping. However, because each product has different parts and specifications in terms of design and manufacturing process, users feel that the virtual objects overlaying real environments in MR are visualized differently, depending on the scale and color used by the MR device. In this paper, we compare the effect of scale and color parameters on users’ perceptions in using different types of MR devices to improve their MR experiences in real life. We conducted two experiments (scale and color), and our experimental study showed that the subjects who participated in the scale perception experiment clearly tended to underestimate virtual objects, in comparison with real objects, and overestimated color in MR environments.

Augmented Reality and Mixed Reality Measurement Under Different Environments: A Survey on Head-Mounted Devices

“…In the right side of Figure 8, we divide the data processing method into two categories: manual observation (Manual) ( [61], [73]) and computer program calculation (Program) ( [62], [115]). These two methods represent how the experimenter processes the data obtained via the measurement method and detailed procedure mentioned above.…”

“…In this diagram, the number of measurement-related papers assigned to each category appears in the upper right corner of that category (some papers may be classified in more than one category). First, we divide papers into four categories according to the main environmental factors manipulated and/or assessed in the papers, which are: indoor environment vs. outdoor environment (In/Out) [55]- [58], virtual environment vs. virtual/real environment (Real/Virtual environment) [59], [60], color difference [61], [62], and luminance difference [63], [64]. (The reference list for each environmental factor is listed in the Appendix A) We provide more detailed information about these four environmental factor categories in section V.…”

“…This classification is based on whether the experiment requires any type of response or input behavior from participants. Examples of users' feedback include asking participants to report a target's color [61], [67], to fill in a questionnaire after the experiment is over [6], [68], or automatically logged responses, such as time spent on achieving pre-set goals [53], [69], or accuracy in putting virtual objects in the correct position in the environment [70], [71]. Studies that incorporate users' responses are the most common category among the types of measurement, likely because capturing direct feedback from users is a quick and easy way to obtain experimental data.…”

“…In addition, [97] introduced an extended color discrimination model to address the issue of the combination of the color displayed by the HMD and the color of the external environment leading to a false perception. By using optical and video seethrough HMDs as evaluation devices in the MR world, [61] examined the effect of color parameters on users' perceptions when using different types of MR devices, showing that users often overestimated color in MR environments. Finally, in recent years, high-fidelity color in MR environments has been an essential task for every OST-HMD.…”

Effects on Co-Presence of a Virtual Human: A Comparison of Display and Interaction Types

“…XR has received significant attention as a key technology for education, training, gaming, advertising, and shopping given its ability to add effective information for our everyday lives [1,2]. This technology can create various situations with useful datasets and interactions to improve a user's experience [3]. In particular, it is actively used for situational training in place of actual people [4].…”
