DARPA is building acoustic GPS for submarines and UUVs


It will utilize undersea sounds instead of satellite feeds.

For all the benefits that the Global Positioning System provides to landlubbers and surface ships, GPS signals can’t penetrate seawater and therefore can’t be used by oceangoing vehicles like submarines or UUVs. That’s why DARPA is creating an acoustic navigation system, dubbed POSYDON (Positioning System for Deep Ocean Navigation), and has awarded the Draper group with its development contract.

The space-based GPS system relies on a constellation of satellites that remain in a fixed position relative to the surface of the Earth. The GPS receiver in your phone or car’s navigation [...]

The creators of Siri just showed off their next AI assistant, Viv, and it’s incredible

By Ben Popper

Viv wowed the crowd during a public demo in New York

Dag Kittlaus and Adam Cheyer created the artificial intelligence behind Siri, Apple’s iconic digital assistant, and one of the first modern apps to capably handle natural language queries on a smartphone. Today the pair showed off their newest creation, Viv, a next generation AI assistant that they have been developing in stealth mode for the last four years. The goal was to create a better version of Siri, one that connected to a multitude of services, instead of routinely shuffling queries off to a basic web search. During a 20-minute demo onstage at Disrupt NYC, Viv flawlessly handled a dozen [...]

The Eyse camera shows friends what you’re doing in virtual reality

By Ashley Carman

The glory of virtual reality is to live in another person’s shoes — to feel what they feel, experience what they experience, and see what they see. The Eyse camera, which launches on Kickstarter today, aims to make that a possibility for anyone with a smartphone. Eyse’s promotional video shows a grandma attending her grandson’s birthday party from afar and friends out hiking projecting the scenery to someone at home. It’s a pleasant vision, and really, if this camera works, it’d be really cool. But still, it’s pretty expensive for something being marketed as a toy, with it being sold at $299 for the early bird special. That [...]

Chainless electric bicycles are probably on the way

By Micah Singleton

Bike2’s electric motor is intriguing, but raises questions

Bike2 has built a chainless electric bike motor that it hopes will become a major part of bicycle manufacturing moving forward. The chainless e-drive system will allow manufacturers (at whom it’s targeted) to outfit standard bicycles with an electric motor that can be recharged as the user pedals.

What Bike2 hasn’t discussed is what happens when your bike runs out of juice. It’s fully electric, so there’s no way to manually pedal like you would with a chain-drive bike. Does it turn into a stationary bike until you manually recharge it by pedaling? [...]
