CoSync lets other people use your phone’s camera without ever touching your phone

Add as a preferred source on Google

cameraYou know that moment when someone famous walks down the street and there’s a sudden pandemonium? You want to snap a picture of said famous person, then all of a sudden some super tall guy gets in your way and just won’t budge. Not only is he blocking your view, now you can’t Instagram whatever it was you wanted to show off. In most circumstances, this would end with you looking over at the person perfectly placed to get the ideal shot with a mixture of dejection and jealousy. So what if you could just use their phone’s camera to get a shot for yourself?

A new system called CoSync aims to make that kind of inter-device sharing possible. Created by a team at the Massachusetts Institute of Technology led by Eyal Toledano, CoSync is a software that allows multiple mobile devices to link up via Bluetooth or Wifi, and offer users the ability to share features of each device from camera to microphone or similar inputs.

In a test carried out by Toledano using a prototype system, six different phones were linked and controlled by one “master” device. That master device sent a signal to all six phones, telling them use their camera flash on a specifically timed instance so that all angles were evenly lighted and the final picture avoided overexposure. The result was compared to pictures taken with a single device, and was judged to have outperformed each one in terms of lighting and final photograph. Such timed multiple flashes, Toledano explains, could also be used to avoid red-eye in photographs in future.

In a separate test, multiple phones placed around two people throwing a ball back and forth managed to capture a series of staggered images that, according to a report in New Scientist, allowed Toledano and his team to “recreate the ‘bullet time’ effect pioneered in the film The Matrix.”

The benefits of the CoSync technology are clear; they’ll allow for the quicker dissemination of information and experience, especially for smaller, more intimate events where only a few would have the chance to experience what was happening otherwise. The potential use of the technology as a security system or way to keep track of a fast-moving event is also there…

Still, as with most sharing innovations, there is a potential for abuse with CoSync. After all, this is essentially TeamViewer for mobile devices, albeit within certain parameters; Allowing remote access for laptops and desktop systems has opened virtual doors for hackers to hijack the computers in question. If you open your phone’s camera up to other people to use, would it really be that much of a surprise if they started taking pictures or recorded sound of things you would rather keep private?

Virgin Galactic is charging $750,000 for three minutes of weightlessness, and nearly 700 people are already in the queue

I’ll be honest with you. Three minutes of weightlessness for the price of a very nice house sounds absurd to me. Even so, hundreds of people have already lined up to experience it.

Most recently, Virgin Galactic unveiled Apeiron, the first spaceplane in its new Delta class. The company flew it from its Arizona factory to Spaceport America in New Mexico, where it will begin flight testing.

Google has been finding more ways to make Gemini a part of your daily routine, from putting together playlists to ordering groceries through your favorite apps. Now it's expanding those capabilities to more services, with Google Search joining in, too.

The company has announced a new Connected Apps Platform that makes it easier for developers to bring their services to both Gemini and Search. Alongside this, Google is adding new partners to its growing lineup, bringing more of the apps people already use into its AI ecosystem.

AI bots are now trying to sabotage public health policies, like banning disposable vapes
Thousands of AI bots voted in a public health poll to block sales restriction on disposable vapes. It's like Big Tobacco is back from the dead.

In the broad context of AI and its perceived harms, health and medical risks often pop up in the conversation. The warnings even come from frontier AI labs, such as ChatGPT-maker OpenAI and Anthropic, both of which have warned about misusing AI to cook up bioweapons. Security experts have already spotted a few such incidents in the wild, especially with the usage of AI models without any solid guardrails. 

Well, it appears that the risks run deeper. As per an analysis appearing in the British Medical Journal (BMJ), AI bots are now being deployed to influence public policies governing health risks to citizens. In this instance, an attempt was made using AI bots to thwart regulations that aim to restrict the sale of disposable vapes, all while disguising the manipulation efforts as a response from real humans.
