Simple, accurate, and efficient: Improving the way computers recognize hand gestures

『V』πšƒ『B』Casts┋
In the 2002 science fiction blockbuster film "Minority Report," Tom Cruise's character John Anderton uses his hands, sheathed in special gloves, to interface with his wall-sized transparent computer screen. The computer recognizes his gestures to enlarge, zoom in, and swipe away. Although this futuristic vision for computer-human interaction is now 20 years old, today's humans still interface with computers by using a mouse, keyboard, remote control, or small touch screen. However, much effort has been devoted by researchers to unlock more natural forms of communication without requiring contact between the user and the device. Voice commands are a prominent example that have found their way into modern smartphones and virtual assistants, letting us interact and control devices through speech.

Meta CEO Mark Zuckerberg announced yesterday that the company is swinging away from its efforts to corral its content. Meta is suspending its fact-checking program to move to an X-style Community Notes model on Facebook, Instagram and Threads.

Well, alongside donating to Donald Trump’s inauguration fund, replacing policy chief Nick Clegg with a former George W. Bush aide and even adding Trump’s buddy (and UFC CEO) Dana White to its board… yeah. Probably. Meta blocked Trump from using his accounts on its platforms for years after he stoked the flames of the attempted coup of January 6, 2021. At the time, Zuckerberg said, “His decision to use his platform to condone rather than condemn the actions of his supporters at the Capitol building has rightly disturbed people in the US and around the world.” But who cares about that when you could get some sweet favor with the...

Researchers have uncovered a hidden split in the venom of Australia’s deadly Eastern Brown Snake. Southern populations create rock-solid blood clots, while northern snakes produce fragile clots that collapse almost instantly — two very different paths to the same deadly outcome. This discovery raises urgent concerns about whether current antivenoms, made from pooled venoms of [...] http://dlvr.it/TMhqWS

If the weather remains favorable and no technical issues stop it, the New Shepard vehicle carrying six people will be lifting off today at 9:45AM Eastern time. It's Blue Origin's third ever crewed mission and the first time that a flight will be at full capacity with six passengers onboard. One of those passengers is Laura Shepard Churchley, daughter of Alan Shepard who's known for being the first American to go to space. She'll be making the trip with Good Morning America co-host Michael Strahan as guests of the Jeff Bezos-owned aerospace company. The trip's paying passengers are technology-focused venture fund founder Lane Bess and his child Cameron Bass aka MeepsKitten on Twitch, Voyager Space CEO Dylan Taylor and engineer/Starfighters Aerospace volunteer pilot Evan Dick. Blue Origin NS-19 was supposed to make the trip to suborbital space on December 9th, but it was pushed back due strong winds. #NewShepard is on the pad. The mission team is going through nomin...
