What does this research mean for the field?

Inter-object spacing in immersive virtual reality reorganizes visual exploration strategies, with denser layouts inducing more refixations and less stable patterns, while wider spacing increases the contribution of head movements. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.SUPPORTS_CONSENSUS.

What question did this study set out to answer?

To investigate how inter-object spacing influences visual search strategies, eye-head coordination, and visual crowding in dense immersive virtual reality environments.

Overview

Experimental study demonstrates that inter-object spacing reorganizes gaze and head search dynamics in virtual reality, indicating that crowding and scene scale jointly govern exploration.

Key Points

To investigate how inter-object spacing influences visual search strategies, eye-head coordination, and visual crowding in dense immersive virtual reality environments.
Assessed visual search behavior across three inter-object spacing conditions using textured 3D objects with a constant total object count.
Tracked and recorded concurrent eye and head movements during immersive exploration in virtual reality.
Performed detailed scanpath analyses evaluating refixation frequency, exploration path stability, normalized exploration costs, and head movement contributions.
Wider spacing increased total search time and fixation count while reducing mean fixation duration and requiring greater head movement involvement.
Dense object layouts induced more refixations, frequent directional changes, and less stable visual exploration patterns, producing the highest relative exploration cost per unit distance.
