摘要
为改善虚拟交互界面的操作效率,将人视觉注意机制融入到虚拟交互界面中,提出一种基于视觉注意机制的虚拟环境交互界面优化模型。根据人眼视觉注意机制,选出交互元件的色彩、间距和视觉注意等级3个影响因素,建立以用户视觉注意力最高为目标的函数模型。运用MATLAB软件和遗传算法对其目标函数进行求解,将结果应用于某VR系统的交互界面优化。针对优化界面进行眼动实验,结果验证了该模型的可行性,优化后交互界面符合视觉注意机制。
To improve the operation efficiency of virtual interaction interface,a virtual environment interaction interface optimization model based on visual attention mechanism was presented,which integrated human visual attention mechanism into virtual interaction interface.According to the visual attention mechanism,three influencing factors were selected including color,distance and visual attention level of interactive elements.The functional model aiming at maximizing the visual attention of the user was established.The objective function was solved using MATLAB software and genetic algorithm.The results were applied to the optimization of the interactive interface of a VR system.Eye movement experiments were carried out on the optimized interface,and the results validated the feasibility of the model.The optimized interface conformed to the visual attention mechanism.
