%X 目的&#65306;本研究旨在探讨动态视觉搜索过程中背景复杂度和搜索目标个数对视觉搜索轨迹的影响。方法&#65306;招募31位受试者通过眼动仪收集其在空白背景、低复杂度背景和高复杂度背景下的单目标、双目标和三目标视觉搜索任务中的眼动数据。结果&#65306;(1) 背景复杂度对动态视觉搜索影响较小。(2) 随着搜索目标数量增加&#65292;动态视觉搜索难度显著提高。(3) 搜索目标消失后&#65292;受试者的视觉搜索轨迹大致呈直线&#65292;方向与搜索目标消失前的运动方向相反或相同。结论&#65306;本研究填补了对视觉搜索目标消失后的动态视觉搜索轨迹的研究空白&#65292;为理解动态视觉搜索提供了关键见解。<br>Objective: This study aims to explore the impact of background complexity and the number of search targets on visual search trajectories during dynamic visual search processes. Methods: Thirty-one participants were recruited, and their eye movement data were collected using an eye tracker during single-target, dual-target, and triple-target visual search tasks in blank, low-complexity, and high-complexity backgrounds. Results: (1) Background complexity has a minor impact on visual search. (2) As the number of search targets increases, the difficulty of visual search significantly rises. (3) After the disappearance of search targets, participants&#8217; visual search trajectories generally follow a straight line, either in the opposite or the same direction as the motion before the target disappearance. Conclusion: This study addresses the research gap in dynamic visual search trajectories after the disappearance of search targets, providing crucial insights for understanding dynamic visual search.
