Luminant landscapes: Optimizing locomotion and interaction invirtual environments

Abstract

This study investigates the impact of color and luminance on locomotion and interaction within virtual environments, considering varying light intensity and transparency levels. The primary objective is to enhance immersion and accuracy in interaction and teleportation within virtual landscapes. Through virtual reality experiments conducted in architectural environments, significant immersion effects are observed, particularly through locomotion and interaction involving touch. Eye- tracking locomotion is also explored, enabling instantaneous motion by gazing, highlighting the importance of clear visual cues aligned with wayfinding principles for successful performance. Recognizing color and luminance as crucial depth cues, the study delves into their role in object distance perception within virtual environments. A forced-choice pairwise comparison experiment is employed, and data is evaluated using the Kendall coefficient of agreement and consistency. By examining 12 color conditions across four light intensity and object transparency levels, the research challenges conventional beliefs regarding color perception in specific virtual environmental conditions. Contrary to previous assumptions, the study reveals nuanced relationships between warm colors, luminance rates, and perceived distance, underscoring the complexity of color and luminance effects in virtual contexts. The findings of this research offer valuable guidance for the design of virtual reality interfaces, particularly in terms of color and lighting selection. By optimizing these elements, interactions, wayfinding, and eye-tracking locomotion in virtual environments can be enhanced, thereby improving the overall user experience. This study contributes to a deeper understanding of the interplay between visual cues, environmental factors, and user perception in virtual reality, paving the way for more immersive and effective virtual experiences.
