When we last looked in on holographic telepresence tech, a University of Arizona team was impressively streaming near-real-time three-dimensional moving images, offering a glimpse of what telepresence could be once researchers iron out the wrinkles. Now, an MIT team is showing off a simplified scheme for streaming holographic video, using a single Xbox Kinect peripheral and standard graphics chips to create the fastest holographic video yet.
There are two significant points to be made up front about the MIT group's Kinect-based holographic TV project. First, where the Arizona team's holographic display could refresh once every two seconds, MIT's scheme is capable of 15 frames per second—close to the 24 fps required for feature films and the 30 fps necessary for television—so its just shy of creating real time holograms that create the illusion of continuous motion.
Moreover, and perhaps more significantly, pretty much all the components for MIT's setup are off-the-shelf. That means holographic telepresence and holographic entertainment may not be too terribly far from reality.
The researchers managed all this by tapping what are known as diffraction fringes to create an object's 3-D shape. When light bounces off of an object, it does so at an infinite number of angles. The MIT team had to create a system that could capture the light intensity of image pixels and their distances from the camera—information that is used to create a diffraction fringe pattern that can bend light in predictable ways—and transmit that data live.
Once the data is transmitted to a computer at the receiving end, a PC with three commercial graphics processing units computes that data into diffraction patterns, which in turn can recreate the image as a hologram that the viewer can view in true 3-D. That is, the viewer can walk around the object and view it from different perspectives. Such live-streaming of holograms doesn't just bring Preincess Leia-like holographic telepresensce a big step closer, but opens the door to holographic television—technology that could bring entertainment into living rooms in a way that surpasses even the best 3-D televisions.
The one component of MIT's system that can't be purchased off-the-shelf at an electronics store is the holographic projector itself, which has been under development at MIT for decades and continues to improve. If researchers there can squeeze a few more frames per second out of their GPU/software setup, that display could fairly easily bring holographic video into the mainstream.
See the system in action in the video below. Unfortunately, the 3-D effect doesn't convert well to 2-D video, so without actually being there the hologram looks more like a blur, a fact that's more than made up for by the Princess-Leia-on- Alderaan costuming.lincoln christmas market 2022 christmas stocking christmas jumper dress waitrose christmas food tesco christmas tree charity christmas cards christmas bank holidays 2022 real christmas tree bath christmas market christmas decorations 2022 christmas party outfit small christmas tree garland christmas park christmas christmas cookies christmas events near me christmas trees near me the christmas chronicles christmas mugs christmas ideas crisis at christmas london christmas market christmas party dresses christmas number 1 christmas tree drawing driving home for christmas john lewis christmas advert christmas lights outdoor christmas chronicles 2 sally nightmare before christmas prelit christmas trees christmas gif personalised christmas baubles christmas gifts for men christmas presents for mum christmas carol christmas markets 2022 uk wilko christmas tree christmas cake decorations lidl christmas jumper christmas carol vorderman christmas card christmas aesthetic leeds christmas market 2022 christmas desserts christmas acrylic nails christmas cupcakes state pension christmas bonus christmas candles lloyd christmas christmas onesie exeter christmas market rockin around the christmas tree covid lockdown christmas christmas biscuits christmas scene m and s christmas food boys christmas jumper kids christmas jumpers rochester christmas market when is christmas mini christmas tree do they know it's christmas christmas socks matching family christmas pajamas christmas table runner christmas border christmas jumper mens black christmas christmas garland with lights all i want for christmas is you lyrics christmas gonk thursford christmas spectacular christmas cards 2022 christmas family pyjamas dog christmas jumper christmas jumpers uk christmas eve box ideas mumsnet christmas asda christmas pyjamas christmas sale christmas eve box fillers covid lockdown after christmas wham last christmas nottingham christmas market 2022 outdoor christmas tree christmas holidays 2022 christmas window decorations christmas t shirts girls christmas jumper christmas decorations sale how many days to christmas christmas hampers uk christmas flowers christmas lockdown baby's first christmas luxury christmas crackers mens christmas gifts christmas tree clipart personalised christmas cards christmas songs list christmas pudding recipe christmas markets london last christmas song a christmas carol (miniseries) cast john lewis christmas christmas wreaths homebase christmas tree gavin and stacey christmas special christmas tree ideas sheffield christmas market tesco christmas jumpers nottingham christmas market real christmas trees near me christmas day 2022 personalised christmas stocking christmas cardigan last christmas movie manchester christmas market top toys for christmas 2022 christmas gift bags christmas ornaments merry christmas wishes 2022 christmas gifts for mum how the grinch stole christmas christmas jumper women's christmas tree sale 6ft christmas tree sainsburys christmas food christmas crackers uk merry christmas and happy new year the night before christmas christmas movies on netflix southbank christmas market chester christmas market we wish you a merry christmas lyrics christmas earrings christmas tops christmas shop christmas window stickers red christmas nails matalan christmas jumpers christmas card holder christmas drawing christmas menu mcdonalds christmas table centerpiece half christmas tree john lewis christmas christmas advert liverpool christmas market 2022
