Industry and academia have been making great efforts in improving refresh rates and resolutions of display devices to meet the ever increasing needs of consumers for better visual quality. As a result, many modern displays have spatial and temporal resolutions far beyond the discern capability of human visual systems. Thus, leading to the possibility of using those display-eye redundancies for innovative usages. Temporal/spatial psycho-visual modulation (TPVM/SPVM) was proposed to exploit those redundancies to generate multiple visual percepts for different viewers or to transmit non-visual data to computing devices without affecting normal viewing. This paper reviews the STPVM technology from both conceptual and algorithmic perspectives, with exemplary applications in multi-view display, display with visible light communication, etc. Some possible future research directions are also identified.

工业界和学术界一直在努力提高显示设备的刷新率和分辨率，以满足消费者对更好的视觉质量不断增长的需求。结果，许多现代显示器的空间和时间分辨率远远超出了人类视觉系统的分辨能力。因此，导致将那些显示眼的冗余用于创新用途的可能性。提出了时间/空间心理视觉调制（TPVM / SPVM），以利用这些冗余为不同的观看者生成多种视觉感知，或将非视觉数据传输到计算设备而不会影响正常观看。本文从概念和算法角度回顾了STPVM技术，并在多视图显示，可见光通信显示等方面的示例性应用。
