CALL FOR WORKSHOP PAPERS Third International Workshop on Perception-driven Graphics and Displays for VR and AR (PerGraVAR) As part of the IEEE Conference on Virtual Reality and 3D User Interfaces (IEEE VR 2026) Dates: March 21–25, 2026 Location: Daegu, Korea Website: <https://www.pergravar-work.shop/> https://www.pergravar-work.shop/ Important Dates Paper submission deadline: January 8th, 2026 Notification of acceptance: January 15th, 2026 Camera ready: January 28th, 2026 Workshop: March 21 or 22, 2026 (tentative) Call for Workshop Papers We invite researchers and practitioners to submit their work to PerGraVAR, part of IEEE VR 2026. The workshop focuses on techniques that leverage the human visual system to enhance visual experiences and optimize rendering in Extended Reality (XR), covering virtual, augmented, and mixed reality. As XR technologies evolve rapidly with innovations like stereo displays, multi-view systems, holographic displays, lightfield displays, optical see-through devices, and video pass-through systems, new challenges arise in areas such as rendering efficiency, cognitive load management, and cross-platform interoperability. This workshop will foster discussions around these challenges while presenting the latest research on perception-driven graphics and display technologies. Submission Scope We encourage researchers to submit early-stage work, such as initial analyses of user studies, perceptual findings, experimental rendering techniques, or sketches for novel devices. We also welcome position papers that summarize a range of previous approaches (e.g., literature reviews), perceptual findings, or experiences. Papers should be between 2 and 8 pages in length. Topics of interest include but are not limited to: * Novel display devices for XR * Rendering methods that exploit perceptual issues * Gaze-contingent rendering and interaction techniques * Cognitive load management strategies in XR * Perception-driven cloud rendering * Interoperability challenges in XR graphics * Perceptually optimized compression techniques * Perception & cognition models for XR * Saliency and attention models * Validation methodologies and benchmarks (including eye-tracking) * Depth-of-field, vergence-accommodation conflict, stereo disparity manipulation Submission Instructions Submissions must be anonymous, prepared in the IEEE Computer Society VGTC conference format, and submitted in PDF via PCS. Further information and a link to PCS will be announced shortly. Submissions will undergo a double-blind review process, and accepted papers will be published in the IEEE Digital Library. Papers that do not adhere to the formatting guidelines will be desk rejected without further review.
