Robotic exoskeleton can train expert pianists to play faster

A robotic hand exoskeleton can help expert pianists learn to play even faster by moving their fingers for them.

Robotic exoskeletons have long been used to rehabilitate people who can no longer use their hands due to an injury or medical condition, but using them to improve the abilities of able-bodied people has been less well explored.

Now, Shinichi Furuya at Sony Computer Science Laboratories in Tokyo and his colleagues have found that a robotic exoskeleton can improve the finger speed of trained pianists after a single 30-minute training session.

[…]

The robotic exoskeleton can raise and lower each finger individually, up to four times a second, using a separate motor attached to the base of each finger.

To test the device, the researchers recruited 118 expert pianists who had all played since before they had turned 8 years old and for at least 10,000 hours, and asked them to practise a piece for two weeks until they couldn’t improve.

Then, the pianists received a 30-minute training session with the exoskeleton, which moved the fingers of their right hand in different combinations of simple and complex patterns, either slowly or quickly, so that Furuya and his colleagues could pinpoint what movement type caused improvement.

The pianists who experienced the fast and complex training could better coordinate their right hand movements and move the fingers of either hand faster, both immediately after training and a day later. This, together with evidence from brain scans, indicates that the training changed the pianists’ sensory cortices to better control finger movements in general, says Furuya.

“This is the first time I’ve seen somebody use [robotic exoskeletons] to go beyond normal capabilities of dexterity, to push your learning past what you could do naturally,” says Nathan Lepora at the University of Bristol, UK. “It’s a bit counterintuitive why it worked, because you would have thought that actually performing the movements yourself voluntarily would be the way to learn, but it seems passive movements do work.”

As Zuckerberg Goes Around Whining About Biden, He Made Sure To First Get His New Approach Approved By Trump

Remember how Zuckerberg was “done with politics”? Remember how he promised that he was going to stop doing what politicians demanded he do?

Now it turns out that he not only did his big set of moderation changes to please Trump, but did so only after he was told by the incoming administration to act. Even worse, he reportedly made sure to share his plans with top Trump aides to get their approval first.

That’s a key takeaway from a new New York Times piece that is ostensibly a profile of the relentlessly awful Stephen Miller. However, it also has a few revealing details about the whole Zuckerberg saga buried within. First, Miller reportedly demanded that Zuckerberg make changes at Facebook “on Trump’s terms.”

Mr. Miller told Mr. Zuckerberg that he had an opportunity to help reform America, but it would be on President-elect Donald J. Trump’s terms. He made clear that Mr. Trump would crack down on immigration and go to war against the diversity, equity and inclusion, or D.E.I., culture that had been embraced by Meta and much of corporate America in recent years.

Mr. Zuckerberg was amenable. He signaled to Mr. Miller and his colleagues, including other senior Trump advisers, that he would do nothing to obstruct the Trump agenda, according to three people with knowledge of the meeting, who asked for anonymity to discuss a private conversation. Mr. Zuckerberg said he would instead focus solely on building tech products.

Even if you argue that this was more about DEI programs at Meta rather than about content moderation, it’s still the incoming administration reportedly making actual demands of Zuckerberg, and Zuckerberg not just saying “fine” but actually previewing the details to Miller to make sure they got Trump’s blessing.

Earlier this month, Mr. Zuckerberg’s political lieutenants previewed the changes to Mr. Miller in a private briefing. And on Jan. 10, Mr. Zuckerberg made them official….

This is especially galling given that it was just days ago when Zuckerberg was whining about how unfair it was that Biden officials were demanding stuff from him (even though he had no trouble saying no to them) and it was big news! The headlines made a huge deal of how unfair Biden was to Zuckerberg. Here’s just a sampling.

Notably absent from this breathless coverage was any mention that Trump was the one who actually threatened to imprison Zuckerberg for life. Or that his incoming FCC chair threatened to remove Section 230 if Meta didn’t stop fact-checking.

Also conveniently omitted was the fact that the Supreme Court found no evidence of the Biden administration going over the line in its conversations with Meta. Indeed, a Supreme Court Justice noted that conversations like those that the Biden admin had with Meta happened “thousands of times a day,” and weren’t problematic because there was no inherent threat or direct coordination.

Yet, here, we have reports of both threats and now evidence of direct coordination, including Zuckerberg asking for and getting direct approval from a top Trump official before rolling out the policy.

And where is this bombshell revelation? It’s buried in a random profile piece puffing up Stephen Miller.

It’s almost as if everyone now takes it for granted that any made-up story about Biden will be treated as fact, and everyone just takes it as expected when Trump actually does the thing that Biden gets falsely accused of.

With this new story, don’t hold your breath waiting for the same outlets to give this anywhere near the same level of coverage and outrage they directed at the Biden administration.

It’s almost as if there’s a massive double standard here: everything is okay if Trump does it, but we can blame the Biden admin for things we only pretend they did.

The US press walks in lockstep with the Trump Fascist movement.

NY Post: Fact Checking Is Now Censorship

This was inevitable, ever since Donald Trump and the MAGA world freaked out when social media’s attempts to fact-check the President were deemed “censorship.” The reaction was both swift and entirely predictable. After all, how dare anyone question Dear Leader’s proclamations, even if they are demonstrably false? It wasn’t long before we started to see opinion pieces from MAGA folks breathlessly declaring that “fact-checking private speech is outrageous.” There were even politicians proposing laws to ban fact-checking.

In their view, the best way to protect free speech is apparently (?!?) to outlaw speech you don’t like.

This trend has only accelerated in recent years. Last year, Congress got in on the game, arguing that fact-checking is a form of censorship that needs to be investigated. Not to be outdone, incoming FCC chair Brendan Carr has made the same argument.

With last week’s announcement by Mark Zuckerberg that Meta was ending its fact-checking program, the anti-fact-checking rhetoric hasn’t slowed down one bit.

The NY Post now has an article with the hilarious headline: “The incredible, blind arrogance of the ‘fact-checking’ censors.”

So let’s be clear here: fact-checking is speech. Fact-checking is not censorship. It is protected by the First Amendment. Indeed, in olden times, when free speech supporters would talk about the “marketplace of ideas” and the “best response to bad speech is more speech,” they meant things like fact-checking. They meant that if someone were blathering on about utter nonsense, then a regime that enabled more speech could come along and fact-check folks.

There is no “censorship” involved in fact-checking. There is only a question of how others respond to the fact checks.

[…]

There’s a really fun game that the Post Editorial Board is playing here, pretending that they’re just fine with fact-checking, unless it leads to “silencing.”

The real issue, that is, isn’t the checking, it’s the silencing.

But what “silencing” ever actually happened due to fact-checking? And when was it caused by the government (which would be necessary for it to violate the First Amendment)? The answer is none.

The piece whines about a few NY Post articles that had limited reach on Facebook, but that’s Facebook’s own free speech as well, not censorship.

[…]

The Post goes on with this fun set of words:

Yes, the internet is packed with lies, misrepresentations and half-truths: So is all human conversation.

The only practical answer to false speech is and always been true speech; it doesn’t stop the liars or protect all the suckers, but most people figure it out well enough.

Shutting down debate in the name of “countering disinformation” only serves the liars with power or prestige or at least the right connections.

First off, the standard saying is that the response to false speech should be “more speech” not necessarily “true speech” but more to the point, uh, how do you get that “true speech”? Isn’t it… fact checking? And, if, as the NY Post suggests, the problem here is false speech in the fact checks, then shouldn’t the response be more speech in response rather than silencing the fact checkers?

I mean, their own argument isn’t even internally consistent.

They’re literally saying that we need more “truthful speech” and less “silencing of speech” while cheering on the silencing of organizations who try to provide more truthful speech.
