Gaze-contingent multiresolutional displays (GCMRDs) center high-resolution information on the user's gaze position, matching the user's area of interest (AOI). Image resolution and details outside the AOI are reduced, lowering the requirements for processing resources and transmission bandwidth in demanding display and imaging applications. This review provides a general framework within which GCMRD research can be integrated, evaluated, and guided. GCMRDs (or "moving windows") are analyzed in terms of (a) the nature of their images (i.e., "multiresolution," "variable resolution," "space variant," or "level of detail"), and (b) the movement of the AOI (i.e., "gaze contingent," "foveated," or "eye slaved"). We also synthesize the known human factors research on GCMRDs and point out important questions for future research and development. Actual or potential applications of this research include flight, medical, and driving simulators; virtual reality; remote piloting and teleoperation; infrared and indirect vision; image transmission and retrieval; telemedicine; video teleconferencing; and artificial vision systems.
注视点相关的多分辨率显示器（GCMRDs）将高分辨率信息集中于用户的注视位置，与用户的感兴趣区域（AOI）相匹配。AOI之外的图像分辨率和细节会降低，从而降低了对要求苛刻的显示和成像应用中的处理资源和传输带宽的要求。本综述提供了一个通用框架，在此框架内可以对GCMRD研究进行整合、评估和指导。从以下两个方面对GCMRDs（或“移动窗口”）进行了分析：（a）其图像的性质（即“多分辨率”、“可变分辨率”、“空间可变”或“细节级别”），以及（b）AOI的移动（即“注视点相关”、“中央凹”或“眼动跟踪”）。我们还综合了关于GCMRDs的已知人为因素研究，并指出了未来研发的重要问题。该研究的实际或潜在应用包括飞行、医疗和驾驶模拟器；虚拟现实；远程驾驶和遥控操作；红外和间接视觉；图像传输和检索；远程医疗；视频电话会议；以及人工视觉系统。
