Journal of the Society for Information Display

Volume 31 contains 12 issues of the Journal of the Society for Information Displays (JSID)—a great way to end 2023. JSID achieved a new impact factor milestone, reaching a 2.3. I want to extend heartfelt congratulations to all the authors, reviewers, and associated editors who contributed to this success. I am confident that JSID and the display community will continue to prosper in 2024. Volume 32 of 2024 will feature the best articles from Display Week 2024, the International Conference on Display Technology (ICDT) 2023 and 2024, and International Display Workshops (IDW) 2023. We also are working on two special issues that focus on AR/VR/MR and quantum dots (QDs) and their applications in displays. We will publish these issues during the second quarter.

Toward physically realistic vision in teleoperation: A user study with light-field head mounted display and 6-DoF head motion | Nicolai Bechtel et al. | https://doi.org/10.1002/jsid.1262

The main limitation for HMDs is the mismatch of the 3D distance and the focal distance of visualized objects (vergence-accommodation conflict, VAC) in displays with fixed focal distance that leads to eye strain after extended use. Here, the authors applied a light-field HMD, providing close-to-continuous depth information to the user to avoid VAC. They also deployed a time-of-flight sensor to generate a 2.5D environment model. The displayed content is processed with image-based rendering, allowing a 6-degree-of-freedom head motion in the visualized scene. Reduction of visual effort for the user is confirmed in an abstract depth-matching task.

The authors demonstrated a focal surface projection to solve the narrow depth-of-field problem in projection-mapping applications. They applied a phase-only spatial light modulator to realize nonuniform focusing distances, whereby the projected content appears focused on a surface with considerable depth variations. The feasibility of the proposed technique was validated through a physical experiment.

Modern virtual-real fusion (VRF) technology has the problem of single-function and fixed integration, limiting the popularization and application of VRF technology. In this article, the authors proposed a framework named synchronous mixed reality (SMR) to personalize the VRF system and maintain the balance between interaction efficiency and environmental immersion. The authors combine an instance segmentation algorithm with an interaction prediction algorithm. To evaluate the effectiveness of the SMR framework, the authors designed three scenarios based on the interaction properties of physical objects and measured environmental immersion, systematic interaction efficiency, and user experience. The results confirm that the SMR framework meets diverse needs in various conditions while balancing immersion and interaction efficiency.
