MIT researchers are making progress with their "Princess Leia" hologram demo, a system that uses Microsoft Kinect to capture live 3D data and transmit it over the Net to a holographic projector. I first saw a previous generation of this projector demonstrated more than a dozen years ago by the late holography pioneer Professor Stephen Benton. The technology blew me away then and it's come a long way, even though the effect may not translate so well in the video above. From New Scientist:
The real holographic image couldn't match the resolution achieved by special effects in the movie, (MIT professor Michael) Bove says, but adds, "Princess Leia wasn't being transmitted in real time. She was stored" in R2-D2's memory.
Bove's group started with an array of 16 low-resolution infrared cameras, spaced evenly along a metre-long line. Computer processing combined the images to generate the data needed for the 3D holographic projector at the rate of 15 frames per second.
The next step came in late December when they bought their first Kinect, and hacked the camera system made by PrimeSense of Israel, which records three-dimensional profiles by projecting a grid of laser light onto a scene. This approach, called structured light, yields resolution of 640 by 480 pixels, three times higher than each infrared camera. That was good enough to record the holographic Princess Leia scene shown here.
California assemblyman Jim Cooper (D-9th) has copy-pasted New York assemblyman Matthew Titone’s (D-61st) insane, reality-denying bill that bans companies from selling smartphones with working crypto on them, introducing nearly identical measures in the California legislature.
Trumpscript — a python variant — only allows numbers over 1,000,000; has no import statements (all declarations must be homegrown); only has integers because floating-point numbers are un-American (America never does anything halfway); only allows popular words and the names of politicians as variable names; limits error messages to direct Trump quotes; and requires that […]
“Radical ecology” has come to mean a kind of left-wing back-to-the-landism that throws off consumer culture and mass production for a pastoral low-tech lifestyle. But as the brilliant science journalist and Marxist Leigh Phillips writes in Austerity Ecology & the Collapse-Porn Addicts: A Defence Of Growth, Progress, Industry And Stuff, if the left has a future, it has to reclaim its Promethean commitment to elevating every human being to a condition of luxurious, material abundance and leisure through technological progress.
Light used to just be one of two things: on or off. Simple as that. Either a flood of yellow or total darkness. Then the dimmer switch happened and you could adjust the brightness to meet your seductive needs and suddenly everyone looked a little better in the gentler light. And now your luminary universe […]
Projects will always need management. And now with the tech gold rush it feels like there are more projects than ever with fewer managers than there’s demand for. But it takes too much time and money to go back to school full time so luckily the Project Management Professional certification training course is now 96% […]
If you’ve been blessed enough to avoid them yourself, you’ve definitely heard the horror stories. Late night, crushing out a ton of work, writing, coding, anything, then boom – your computer crashes. The battery blows, you spill water or coffee all over the place, or it just shuts down with no explanation, and you’re screwed. […]
