随着人机系统的日益复杂化和界面视觉信息的日益增加，如何提高视觉信息呈现的有效性，已成为工程心理学研究的核心问题。已有研究提出了视觉突显等多种技术，但这些传统技术均无法实现视觉信息随操作者的即时交互操作特性而发生动态变化的需求，也无法满足操作者对复杂视觉信息进行高效操作的要求。基于此，本项目开发了一种基于视线定位的视觉信息显示技术。该技术通过操作即时的视线定位信息，实现视觉信息随操作者的视线定位而发生动态实时的变化，并成功构建了实验平台。基于该实验平台，本项目设计了系列实验研究来探索这种新型信息显示技术在阅读、搜索等典型视觉任务操作中的应用规律及其影响因素。基于视线定位的视觉信息显示技术实现了视觉信息从“静态”到“动态实时交互式”显示的突破，丰富了人机视觉信息显示技术的设计思路，为最终解决界面视觉信息呈现的有效性问题提供了可靠的途径和可行的方法。

Modern human-machine interactions include two major features: the complex interactive operations and the excessive amounts of visual information presentation has become one of the major research topics in engineering psychology. To overcome the limitations in existing visual presentation techniques, which can no longer efficiently presenting visual information for modern human-machine interactions, we have developed a novel Gaze-based Dynamic Visual Presentation technique (GDVP). Based on high-frequency eye-tracking techniques, the GDVP is capable of dynamically updating the visual information on displaying devices in response to users’ looking patterns, therefore achieving highly efficient operations. Moreover, we have built an experiment system based on the GDVP technique to further investigate how to improve the efficiency of visual presentation for modern human-machine interactions. Specifically, the current project proposed a series of studies, which are designed to investigate how the GDVP can improve the current visual user interface design in typical interactive operations, such as reading and searching. The GDVP not only advances visual presentation from a “static” to a “dynamic” manner, perhaps more importantly, it also broadens the current views of visual presentation design in general. We believe that the GDVP would be a key technique to address the issue of the low efficiency in visual information presentation designs.
