Brain-controlled VR game hints at a hands-free future

We may be a long way off from a Holodeck-like virtual reality where your body is the controller, but Neurable might have the next closest thing. It recently unveiled a prototype peripheral that adds brain control to VR experiences. The device replaces the regular strap on an HTC Vive and uses specific brain signals (event-related potentials, not the EEG patterns you usually see) to trigger actions. In a showcase game, Awakening, you use your mind to escape a lab as if you had telekinetic powers — you don’t have to hold plastic wands as you battle robots and grab objects.

Games are the first application, and Neurable tells IEEE Spectrum it’s hoping to bring its experience to VR arcades in 2018. The brain controller should be slicker, too, so the bulky design you see here (which makes you look like you’re part of a lab experiment, really) won’t last long.

However, the company clearly has larger ambitions. It sees brain control as a big step up in VR interfaces. When done well, it both eliminates the learning curve (you just think about what you want to do) and allows for input that’s difficult or impossible when you can’t see your body, such as fast text input. This isn’t guaranteed to completely replace physical controls, at least not for a while (many games and other apps will still benefit from hands-on interaction), but it does hint at a future where you don’t need controllers for every instance of interactive VR, even when they’re relatively complex.

Instagram livestreamers can add a guest to their broadcasts

Livestreaming is becoming a major part of social networks — Instagram, Twitter (via Periscope) and Facebook have all been pushing it in our faces for a while now. They all work the same, more or less, but Instagram is adding an intriguing new feature to the mix. Today, the company announced that some users will be able to add a "guest" to their live broadcasts, essentially adding a second contributor to the livestream. This lets users have a live conversation with a friend and broadcast both sides of that chat to your followers.

Once you have a guest in your livestream, you can boot them out any time you want and add another, or the person you invited can also leave at any time. When you’re livestreaming with a guest, followers will just see the screen split 50/50 between what your camera is broadcasting and what the other person in the stream is shooting. For now, it seems you can only add one person to the stream; there’s no word on whether Instagram will let you add multiple guests, but it seems like that could get pretty complicated on a small screen.

Instagram says it is only testing out this feature with a "small percentage" of users for now, but it’ll roll out globally in the coming months.

“Podcasting patent” is totally dead, appeals court rules


reader comments

A federal appeals court has upheld a legal process that invalidated the so-called “podcasting patent.” That process was held by a company called Personal Audio, which had threatened numerous podcasts with lawsuits in recent years.

On Monday, the US Court of Appeals for the Federal Circuit affirmed the April 2015 inter partes review (IPR) ruling—a process that allows anyone to challenge a patent’s validity at the US Patent and Trademark Office.

“We’re glad that the IPR process worked here, that we were allowed to go in and defend the public interest,” Vera Ranieri, an EFF attorney who worked on the case, told Ars. (She told Ars that her favorite podcast is Lexicon Valley.) There had been a question as to whether EFF had standing during the appellate phase of the case.

Back in 2013, Personal Audio began sending legal demand letters to numerous podcasters and companies, like Samsung, in an apparent attempt to cajole them into a licensing deal, lest they be slapped with a lawsuit. Some of those efforts were successful: in August 2014, Adam Carolla paid about $500,000.

As Personal Audio began to gain more public attention, the Electronic Frontier Foundation, however, stepped in and said that it would challenge Personal Audio’s US Patent No. 8,112,504, which describes a “system for disseminating media content representing episodes in a serialized sequence.” In the end, EFF raised over $76,000, more than double its initial target.

Monday’s news gained some approval from at least one big-name podcaster: Marc Maron.

A years-old saga

As Ars reported previously, the history of Personal Audio dates to the late 1990s, when founder Jim Logan created a company seeking to create a kind of proto-iPod digital music player. But his company flopped. Years later, Logan turned to lawsuits to collect money from those investments. He sued companies over both the “episodic content” patent, as well as a separate patent, which Logan and his lawyers said covered playlists. He and his lawyers wrung verdicts or settlements from Samsung and Apple.

Unlike many non-practicing patent owners, which are sometimes derided as “patent trolls,” Logan didn’t hide from his patent campaign. He spoke publicly about his company’s history and his reason for pursuing patent royalties, giving interviews to National Public Radio and the CBC and doing a Q&A on Slashdot.

Personal Audio did not immediately respond to Ars’ request for comment. The company has not filed any new lawsuits since it sued Google in September 2015 over two other audio-related patents.

Mazda says it has made a long-awaited breakthrough in engine technology

Mazda

Fresh on the heels of last week’s tie-up with Toyota, on Tuesday Mazda announced it’s finally made a breakthrough in gasoline engine technology. Mazda is calling it Skyactive-X; we know it better as homogenous charge compression ignition, or HCCI. It should mean a 20-30 percent boost in efficiency compared to Mazda’s current gasoline direct-injection engines, and we may well see it in the next revision to the Mazda 3.

HCCI engines have been one of those “if only” technologies for some time now. Kyle Neimeyer first covered the idea back in 2012 for Ars as part of a deep dive into new engine tech that could help meet looming efficiency requirements for automakers.

In essence, HCCI is an attempt to run a gasoline engine like a diesel instead. Rather than squirt fuel into a cylinder—done directly, at high pressure, in the case of Mazda’s current gasoline engines—then ignite it with a spark, the fuel and air are well-mixed and then compressed to achieve the bang in suck, squeeze, bang, blow.

Because the fuel and air are so well-mixed, combustion should happen simultaneously at multiple points within the cylinder’s volume, burning more evenly, at a lower temperature, with fewer particulates or nitrogen oxides in the exhaust than a normal spark-ignited gasoline engine or a diesel engine. Making it work is apparently much harder than describing it; at various times General Motors, Volkswagen, Mercedes-Benz, Ford, Honda, and Bosch have all tried their hand at the technology to little avail.

But Mazda is nothing if not stubborn when it comes to eclectic engine technologies; after all, it bravely persevered with the rotary engine for decades. In January, there were signs that it had made real progress with HCCI, and today we have the confirmation as part of a broader announcement from Mazda about its new long-term sustainability plan. Another element of the plan—given the catchy title “Sustainable Zoom-Zoom 2030″—is to start introducing EVs and hybrids “in regions that use a high ratio of clean energy for power generation or restrict certain vehicles to reduce air pollution.”

This engine still has spark plugs!

The new HCCI engines will still use the good-old spark plug; for some operating conditions its better to run it as a conventional spark-ignition engine. Mazda says it has perfected the control issues that let the engine know when to transition between spark ignition and when things can be leaned-out enough to use HCCI.

The engines will also be supercharged, so they will be torquier than the current Mazda gasoline-powered engine range as well as being cleaner and more efficient. (Mazda’s press release says that, volume for volume, they should be comparable to its current turbodiesel range in that regard.)

Reuters reports that Mazda also plans to keep HCCI to itself, although we wonder if that applies to new best friend Toyota.

We know there is a vocal population who would like to see OEMs like Mazda give up development of new internal combustion engine technology all together, focusing instead on fully switching over to battery electric vehicles. These days, national governments are throwing out dates like 2030 and 2040 for banning new fossil-fueled vehicles from sale.

But 2040 is some way off, and if William Gibson has taught us anything, it’s that the future is not evenly distributed. Certainly in the mid-term, there will be a use for hydrocarbon-fueled vehicles, particularly outside of dense urban corridors where average journeys are shorter and recharging infrastructure thicker on the ground. So anything that makes those vehicles cleaner and more efficient ought to be viewed as a good thing.

How Smartphones Are Making Kids Unhappy

Psychologist Jean Twenge says smartphones have brought about dramatic shifts in behavior among the generation of children who grew up with the devices.

For the first time, a generation of children is going through adolescence with smartphones ever-present. Jean Twenge, a professor of psychology at San Diego State University, has a name for these young people born between 1995 and 2012: “iGen.”

She says members of this generation are physically safer than those who came before them. They drink less, they learn to drive later and they’re holding off on having sex. But psychologically, she argues, they are far more vulnerable.

“It’s not an exaggeration to describe iGen as being on the brink of the worst mental health crisis in decades,” she writes in a story in The Atlantic, adapted from her forthcoming book. And she says it’s largely because of smartphones.

Twenge spoke to All Things Considered about her research and her conclusions. This interview has been edited for length and clarity.


How does teen behavior now differ from generations past?

Today’s teens are just not spending as much time with their friends in person, face-to-face, where they can really read each others’ emotions and get that social support. And we know from lots and lots of research that spending time with other people in person is one of the best predictors for psychological well-being and one of the best protections against having mental health issues.

What is this generation facing that worries you so much?

iGen is showing mental health issues across a wide variety of indicators. They’re more likely than young people just five or 10 years ago to say that they’re anxious, that they have symptoms of depression, that they have thought about suicide or have even [attempted] suicide. So across the board, there’s a really consistent trend with mental health issues increasing among teens.

Is it specifically the smartphone, or is it social media? Or is it the number of hours per day spent on these things?

So, you look at the pattern of loneliness. It suddenly begins to increase around 2012. And the majority of Americans had a cell phone by the end of 2012, according to the Pew Center.

Given that using social media for more hours is linked to more loneliness, and that smartphones were used by the majority of Americans around 2012, and that’s the same time loneliness increases, that’s very suspicious. You can’t absolutely prove causation, but by a bunch of different studies, there’s this connection between spending a lot of time on social media and feeling lonely.

How much of a factor is parenting?

So I was somewhat surprised when I interviewed iGen teens how many of them are deeply aware of the negative effects of smartphones. Parenting is playing a role. I think many parents are worried about their teens driving, and going out with their friends and drinking. Yet parents are often not worrying about their teen who stays at home but is on their phone all the time. But they should be worried about that. I think parents are worried about the wrong thing.

Can you propose solutions that might help people?

The first is just awareness that spending a lot of time on the phone is not harmless and that if you’re spending a lot of time on the phone, then it may take away from activities that might be more beneficial for psychological well-being, like spending time with people in person.

Then for parents, I think it is [a] good idea to put off giving your child a smartphone as long as you can. If you feel they need a phone, say, for riding a bus, you can get them a flip phone. They still sell them. And then once your teen has a smartphone, there are apps that allow parents to restrict the number of hours a day that teens are on the smartphone, and also what time of day they use it.

GM is selling a $5,000 electric car in China

General Motors will start selling a tiny electric car in China this week that will cost about $5,300 after national and local electric vehicle incentives, according to GM.

For that sort of price, the Baojun E100 is no Cadillac, of course. The two-seat car’s wheelbase — the distance from the center of the front wheels to the center of the rear wheels — is just 63 inches. That’s about 10 inches shorter than Daimler’s (DDAIF) Smart ForTwo, a car that is already remarkable for its stubby proportions.

General Motors could not immediately confirm the full price of the car before incentives.

The E100 is powered by a single 39-horsepower electric motor and has a top speed of 62 miles an hour. The E100 can drive about 96 miles on a fully charged battery, according to GM (GM).

baojun 100 The Baojun E1000 has a top speed of 100 kilometers an hour, or 62 miles an hour.

The E100 does offer some amenities, such as an entertainment system with a 7-inch screen and built-in WiFi. All versions of the car will have parking sensors and pedestrian alert systems among other safety features. High-end models are available with a touchpad and keyless entry.

India to sell only electric cars by 2030

Baojun is a mass-market car brand from General Motors’ SAIC-GM-Wuling joint venture in China. It’s China’s eighth most popular car brand, according to data from LMC Automotive, ranking below brands like Volkswagen, Toyota (TM), Honda (HMC) and Buick.

The E100 is Baojun’s first electric car.

baojun 100 The Baojun E100 is even smaller than a Smart ForTwo.

More than 5,000 people have already registered to buy the first 200 vehicles, according to GM. Another 500 vehicles are being made available this week. Sales will initially be limited to the Guanxi region of southern China. GM couldn’t immediately say how it will choose which potential buyers get to take home the E100.

China is the largest automotive market in the world, and its government is making a big push for electric cars. Already, China accounts for 40% of all electric cars sold worldwide, according to the International Energy Agency.
