题目: Temporal Psycho visual Modulation: a new paradigm of information display
报告人: Xiaolin Wu, Department of Electrical and Computer Engineering, McMaster University
We report on our pioneer research of temporal psycho visual modulation (TPVM): a new paradigm of information display. TPVM can greatly extend the utility and enrich functionality of optoelectronic displays, by exhibiting different images to different viewers all on the same physical display medium without interferences. In TPVM, a display of high refresh rate optically emits so-called atom frames, which are computed via non-negative matrix factorization as bases for a set of target images; different viewers perceive self-intended images by using display-synchronized viewing devices and their own human visual systems to fuse appropriately weighted atom frames. This is essentially a scheme of 2D modulation in visible spectrum, using an optoelectronic modulator coupled with a biological demodulator. TPVM has a wide range of applications, including digital gaming, 3D TV/movie, virtual/augmented reality, scientific/medical visualization, security, visible light communication, etc. This work is featured in MIT Technology Review, Science News, and published in the “Exploratory DSP” column of IEEE Signal Processing Magazine.
