Comparing Perceptual Visual Quality of Hybrid Neural and Ray Tracing in Foveated Rendering

Journal on Interactive Systems
Enabling Foveated Rendering for VR devices displays is fundamental when dealing with real-time ray tracing. Combining traditional methods with Neural based strategies, such as NeRFs and 3D Gaussian Splatting, may impact on leveraging performance even ...

Misinterpreting Electrophysiology in Human Cognitive Neuroscience

Psychophysiology, Volume 63, Issue 4, April 2026.
ABSTRACT An axiomatic view in contemporary neuroscience is that EEG components such as event‐related brain potentials (ERPs) and oscillations are directly interpretable as manifestations of biological processes that support sensory, motor, and cognitive constructs of interest.

Stereoscopic Brightness Roll‐Off in Augmented Reality

Journal of the Society for Information Display, Volume 34, Issue 3, Page 85-98, March 2026.
The increasing demand for power‐efficient immersive augmented reality (AR) displays has led to a growing need for effective power‐saving strategies. Here, the authors investigate for the first time the stereoscopic effectiveness of brightness roll‐off (BRO) for perceptually‐optimized power savings in AR.

Measuring the Luminance Contrast Sensitivity Function in Peripheral Vision

Color Research &Application, Volume 51, Issue 1, January/February 2026.
Luminance contrast detection thresholds of frequencies at eccentricities for a person. ABSTRACT We measured luminance contrast sensitivity functions (CSF) of four subjects by using Gabor stimuli up to 56°, 49°, 84°, and 63° in the nasal, superior, temporal, and inferior directions, respectively, of the left‐eye visual field.

An Electroencephalographic Investigation of the Impact of Eye Movements in a Memory Probe Task

Psychophysiology, Volume 63, Issue 1, January 2026.
ABSTRACT Lateral saccades represent a major source of noise and confounds, particularly for event‐related potentials (ERPs) that rely on hemispheric imbalances in neural activity elicited by lateralized stimuli during central fixation. These include lateralized ERPs such as the contralateral delay activity (CDA), which indexes visual working memory ...

Foveated Path Tracing with Configurable Sampling and Block-Based Rendering

Path tracing offers high-fidelity rendering but remains impractical for real-time applications due to slow convergence and noise. We present a dynamic foveated path tracing technique that leverages visual perception by reducing sampling towards ...

TinyGaze v2: A Systems Benchmark for Practical Gaze Estimation on Edge Hardware

Advances in Human-Computer Interaction, Volume 2026, Issue 1, 2026.
The deployment of robust, real‐time gaze estimation on commodity hardware is critical for pervasive gaze‐aware augmented and virtual reality (AR/VR). While the computer vision community has made significant progress in accuracy, a pervasive focus on leaderboard performance has created a gap between research and the system‐level constraints of real ...

A Unified Real-Time Spatial and Chromatic Foveated Rendering in VR

We present a real-time, gaze-contingent foveated rendering framework for virtual reality (VR) that integrates variable rate shading (VRS), foveated mipmap, and foveated color degradation techniques, individually and in combination.

Estimation of horizontal spatial specifications for ideal head-mounted displays in practical conditions

Frontiers in Virtual Reality
This study presents the horizontal spatial specifications required for developing ideal head-mounted displays (HMDs) that provide visual experiences indistinguishable from those obtained without wearing HMDs.
