However, as visual complexity increases, perceptual performance declines, making it more difficult to detect changes quickly and accurately. This study examines how visual features, known for facilitating preattentive processing, impact a change detection task in immersive 3D environments, with a focus on visual complexity, object attributes, and spatial proximity. Our results demonstrate that preattentive processing enhances change detection, particularly when the altered object is spatially isolated and not perceptually grouped with similar surrounding objects. Changes to isolated objects were detected more reliably, suggesting that perceptual isolation reduces cognitive load and draws more attention. Conversely, when a changed object was surrounded by visually similar elements, participants were less likely to detect the change, indicating that perceptual grouping hinders individual object recognition in complex scenes. These results provide guidelines for designing VR applications that strategically utilize spatial isolation and visual features to improve the user experience. --- -->Olfactory Perception and Spatial Reliability: A Comparative Study of Fixed and Mounted Devices in VRhttps://isaac-cho.github.io/publications/kim-2025-olfactory/Wed, 01 Jan 2025 00:00:00 +0000https://isaac-cho.github.io/publications/kim-2025-olfactory/SpherePoser: A Spherical Tangible User Interface for Immersive Object Manipulationhttps://isaac-cho.github.io/publications/lee-2025-sphereposer/Wed, 01 Jan 2025 00:00:00 +0000https://isaac-cho.github.io/publications/lee-2025-sphereposer/<!-- # Publication Types # article-journal = Journal # paper-conference = Conference # workshop = Workshop # poster-abstract = Poster / Abstract # book-chapter = Book Chapter # technical-report-preprint = Technical Report / Preprint -->Enhancing Virtual Teleportation: An Evaluation of a Wearable Olfactory Device with Ventilation for Immersive VR Experienceshttps://isaac-cho.github.io/publications/myung-2024/Mon, 01 Jan 2024 00:00:00 +0000https://isaac-cho.github.io/publications/myung-2024/<!-- # Publication Types # article-journal = Journal # paper-conference = Conference # workshop = Workshop # poster-abstract = Poster / Abstract # book-chapter = Book Chapter # technical-report-preprint = Technical Report / Preprint -->A Comparison Study on Stress Relief in VRhttps://isaac-cho.github.io/publications/han-2023/Sun, 01 Jan 2023 00:00:00 +0000https://isaac-cho.github.io/publications/han-2023/An Interactive Web Interface to Reproduce Key Plots in the Fifth National Climate Assessment Report Using the LOcalized Constructed Analogs 2 (LOCA2)https://isaac-cho.github.io/publications/lee-2023-interactive/Sun, 01 Jan 2023 00:00:00 +0000https://isaac-cho.github.io/publications/lee-2023-interactive/An Overview of the 2nd International Workshop on Extended Reality for Industrial and Occupational Supports (XRIOS)https://isaac-cho.github.io/publications/kim-2023-overview/Sun, 01 Jan 2023 00:00:00 +0000https://isaac-cho.github.io/publications/kim-2023-overview/Enhancing VR Experience using a Mounted Olfactory Devicehttps://isaac-cho.github.io/publications/myung-2023/Sun, 01 Jan 2023 00:00:00 +0000https://isaac-cho.github.io/publications/myung-2023/Folding Rays: a Bimanual Occluded Target Interaction Techniquehttps://isaac-cho.github.io/publications/kim-2023/Sun, 01 Jan 2023 00:00:00 +0000https://isaac-cho.github.io/publications/kim-2023/An Interactive Web Interface to Compare the LOcalized Constructed Analogs 2 (LOCA2) with Its Precursor and CMIP6https://isaac-cho.github.io/publications/cho-2022-interactive/Sat, 01 Jan 2022 00:00:00 +0000https://isaac-cho.github.io/publications/cho-2022-interactive/An Overview of the 1st International Workshop on eXtended Reality for Industrial and Occupational Supports (XRIOS)https://isaac-cho.github.io/publications/jeong-2022-overview/Sat, 01 Jan 2022 00:00:00 +0000https://isaac-cho.github.io/publications/jeong-2022-overview/Advancing the Use of Advanced Metering Infrastructure (AMI) Data through Visual Analyticshttps://isaac-cho.github.io/publications/lawanson-2018/Mon, 01 Jan 2018 00:00:00 +0000https://isaac-cho.github.io/publications/lawanson-2018/Towards a Distributed Infrastructure for Data-Driven Discoveries Analysishttps://isaac-cho.github.io/publications/elshambakey-2017/Sun, 01 Jan 2017 00:00:00 +0000https://isaac-cho.github.io/publications/elshambakey-2017/Evaluating Depth Perception of Volumetric Data in Semi-Immersive VRhttps://isaac-cho.github.io/publications/cho-2012-poster/Sun, 01 Jan 2012 00:00:00 +0000https://isaac-cho.github.io/publications/cho-2012-poster/
