Visual crowding reduces blur sensitivity in peripheral vision: a study using natural textures in virtual reality.

Area of Science:

• Visual Neuroscience
• Extended Reality (XR) Technologies
• Perceptual Psychology

Background:

• Peripheral vision is vital for immersion and navigation in XR.
• Visual crowding, where nearby elements hinder target recognition, is a key challenge in peripheral vision.
• Crowding's impact on XR image processing, particularly blur perception, is under-explored.

Purpose of the Study:

• To investigate the effect of visual crowding on blur perception in natural textures within an XR environment.
• To determine how texture properties influence crowding's impact on blur sensitivity.

Main Methods:

• Participants detected blur in peripheral texture patches.
• Patches were presented in isolation or surrounded by similar textures.
• The influence of texture similarity and inferability on crowding was analyzed.

Main Results:

• Surrounding textures significantly impaired peripheral blur sensitivity.
• Crowding effects were stronger with visually similar target and surrounding textures.
• Crowding was more pronounced when surrounding textures allowed easy inference of the central texture.

Conclusions:

• Visual crowding negatively affects blur perception in XR, dependent on texture properties.
• Findings suggest opportunities for perceptually guided rendering and compression in XR.
• Imperceptible image degradations may be possible without compromising visual quality in XR.
