"TPVM allows concurrent multiple self-intended exhibitions via a common display medium, an optoelectronic-psychovisual process modelled by non-negative matrix factorisation. Different images are perceived by different viewers whose LC glasses modulate the same sequence of atom frames differently," explains (right) Professor Wu.
Displays are capable of showing images at a rate of 240 per second or more, LCD glasses matching this rate, but the human visual system only processing images at a rate of about 60Hz, which allows several image streams to be displayed and separately viewed at the same time.
Technically this wil reduces the amount of real-time processing needed. Headmounted glasses only needed to synchronise with a specific subset of images based on the user's choice or head movement.
Obvious applications will be in gaming, virtual tourism, surgery and reports Technology Review, Wu and Zhai have also identified interesting security applications, scrambling images into several streams to reassemble them through encrypted LCD glasses, or scrambling the keys to prevent on onlooker evesdropping a user's pin number.
