This solar array expands itself at the right temperature

Wouldn’t it be nice to have a solar panel that’s only there when the sun shines on it? That’s the idea behind this research project, which uses shape-shifting materials to make a solar panel grow from a compressed state to an expanded one with nothing more than a change in temperature.

The flower-like prototype device is made of what’s called a “shape-memory polymer,” a material that can be shaped when cool to one form, then when heated will attempt to return to its original, natural configuration. In this case the cool form is a compressed disc, and the warm one is a much wider one.

The transition (demonstrated here in warm water for simplicity) takes less than a minute. It’s guided by a network of hinged joints, the structure of which was inspired by the children’s toy known as a Hoberman sphere, which changes from a small, spiky ball to a larger spherical one when thrown.

The cooled-down material would stay rigid during, say, deployment on a satellite. Then when the satellite enters the sun, the mechanism would bloom into the full-sized array, no power necessary. That would potentially save space on a satellite that can’t quite fit a battery or spare solar array to kick-start a larger one.

For now the transformation is one-way; the larger disc must be manually folded back into the smaller configuration — but one can imagine how once powered up, a separate mechanism could accomplish that, stowing itself away until the next chance to absorb some sunlight appears.

Don’t expect to see this on any spacecraft next year, but it’s definitely a cool (and warm) idea that could prove more than a little useful for small satellites and the like in the future. And who knows? Maybe you’ll have a garden of these little blooming arrays on your roof before that.

The research, from Caltech and ETHZ, is documented in the journal Physics Review Applied.

Apple may finally ditch the troubled butterfly keyboard in future MacBooks

According to Ming-Chi Kuo, Apple will finally start phasing out its “butterfly� keyboard later this year. The keyboard design has had nothing but trouble since it was introduced in 2016, and it seems that Apple has finally had enough, with a new design set to debut in a MacBook Air this year.

HQ Trivia lays off ~20% as it preps subscriptions

HQ Trivia is struggling after a mutiny failed to oust its CEO. Downloads per month are down 92% versus last June according to Sensor Tower. And now four sources confirm that HQ laid off staff members this week. One said about 20% of staff was let go, and another said six to seven employees were departing. That aligns with Digiday reporter Kerry Flynn’s tweet that 7 employees were let go bringing HQ to under 30 (shrinking from 35 to 28 staffers would be a 20% drop).

That will leave the company short-handed as it attempts to diversify revenue with the upcoming launch of monthly subscriptions. “HQ Words Everyday. Coming next month . . .  Bigger prizes . . . More ways to win. $9.99/mo. subscription” the company tweeted from the account for its second game, the Wheel Of Fortune-style HQ Words. The company has been trying to regain momentum with new hosts since the departure of Quiz Daddy aka Scott Rogowsky, HQ Trivia’s original host.

The cuts hit HQ’s HR, marketing, and product engineering teams, according to LinkedIn profiles of employees let go. The cuts could further hamper morale at the startup following a tough first half of the year. HQ Trivia and co-founder Rus Yusupov did not respond to repeated requests for comment.

HQ Trivia employees petitioned to remove co-founder Rus Yusupov from the CEO position

Following the tragic death of co-founder and CEO Colin Kroll, Yusupov retook control. But staff found him difficult to work with as he’d allowed the product to stagnate and popularity to decline. Yusupov was slow to make changes to the app, and “no one wanted to work under Rus” a source told me.

That led 20 of 35 staffers to sign a letter to HQ Trivia’s board asking them to remove Yusupov, though it was never formally sent. Yusupov caught wind of the plot and fired two of the leaders of the petition. That further sunk morale, leading to the exit of HQ Trivia’s SVP of brand partnerships and its marketing manager. The board began a search for a new CEO, though it’s unclear how that’s panned out.

Since then, new games HQ teased in April haven’t materialized as its download rate continued to suffer. It’s dropped to the #731 US game on iOS according to AppAnnie. HQ Trivia saw just 827,000 downloads from January through June 2019, down 92% from the 10.2 million it saw in the same time frame in 2018 according to Sensor Tower. That’s the same percentage drop in downloads from June 2019 versus June 2018, indicating Rogowsky’s replacements that started in April couldn’t turn things around.

Interest in the live game show format seems to be waning as a whole. HQ Trivia fan site HQTrivia.fan shut down this week fearing the end was near for the official game, and the (Business) INSIDER-run clone of the game on Facebook Watch called Confetti stopped airing at the end of June.

Rather than solely monetizing a waning audience via in-app purchases and sponsorships, HQ Words announced it would debut a $9.99 monthly subscription sometime this month that would grant access to winning “bigger prizes”. This could be a smart way to squeeze more dollars out of a smaller but more diehard audience.

While HQ Trivia was an inspiring approach to mobile gaming, its twice-daily games didn’t fit the always-on nature of mobile. It’s failed build a proper onboarding experience that gives users a taste of it games right away rather than forcing them to wait for the next scheduled match as we suggested over a year ago. Gamers are fickle, craving instant gratification, and HQ hasn’t tried to meet them in middle.

Perhaps there’s a future for HQ on cable television, or as a small but steady business on mobile catering to loyalists. But all the unfortunate events and mismanagement may make it difficult to exceed the $100 million valuation it raised money at during its peak.

An optimistic view of deepfakes

Deepfakes are having a moment.

Their dangers are becoming more known and understood. The media is rife with articles detailing the speed at which the technology has grown in sophistication and become more accessible, as well as the risks involved.

Good.

The negative implications of deepfakes are troubling, and the better we understand them, the better we’ll be able to prevent their worst consequences. For better or worse, the technology is here to stay. But there is a “better� here—deepfakes have much in the way of lighthearted upside. 

Though the debate around deepfakes has grown in stature and complexity, we still struggle to agree on a definition of deepfakes. I think of it as any mimicry, manipulation, or synthesis of video or audio that is enabled by machine learning. Face-swapping, body puppetry, copying someone’s voice, and creating entirely new voices or images all fall into this category. Your Photoshop efforts, valiant though they are, don’t.  

Image synthesis and manipulation can be a powerful tool for creators

Visual storytelling is an expensive business. Hollywood studios spend billions on creating spectacle that wows their audience or transports them to another world. The tools they use to do so—the tools these big players use to close the gap between what they can imagine and what they can create—remain prohibitively expensive for most creators, though less so than a decade ago. Deepfake tech incorporates the ability to synthesize imagery, potentially giving smaller-scale creators a similar capacity for bringing imaginative creativity to life.

Synthesia is a company with a commercial product that uses deepfake tech to do automated and convincing dubbing through automated facial re-animation. They shot to prominence with a video that featured David Beckham talking about Malaria in nine languages, but their product could also be used to expand the reach of creators around the world. If you’re a talented artist who isn’t working in one of the world’s dominant languages, it’s potentially career-changing to have access to a product like this, which could make your work viable in additional languages and countries.

Adobe VoCo is software — albeit still at a research and prototyping stage — that makes it easier for creators to produce speech from text and edit it the way they would edit images in Photoshop. So if you want your movie short to be narrated by Morgan Freeman, you might be able to make that happen.

Tinghui Zhou, the founder and CEO of Humen, a company that creates deepfakes for dancing, sums up the industry’s goals: “The future we are imagining is one where everyone can create Hollywood-level content.� (Disclosure: I am an investor in Humen).  

In the same way YouTube and Instagram shrunk the distribution and creation advantage that entertainment companies and famous photographers enjoyed over talented amateurs and enthusiasts, this bundle of technologies might diminish the production advantage currently possessed by big budgets and visual effects houses.

Mimicry and manipulation of real life have always been part of art.

The applications mentioned above are all to do with closing the gap between creators with different resources, but deepfake tech could also enable entirely new forms of content that rest on the ability to mimic and manipulate material. Every medium of entertainment has incorporated the stretching, reflection, contortion, and appropriation of real source material for the purposes of entertainment. 

We can already see the evidence of these new applications in the still-nascent use of deepfake tech today. While face swapping for porn lies at the malicious end of the spectrum, more benignly the technology’s introduction also sparked a wave of face swapping Nicolas Cage into different movies.

It might seem banal, but it was a form of content creation that, while previously technically possible, was practically infeasible before deepfakes. It’s not hard to imagine that the next deepfakes content craze will be driven by automated lip-syncing, dance mimicry, or celebrity voice impressions.

Respeecher and Replica.AI are just two companies making voice mimicry accessible to non-techies. Check out my demo with Replica’s tech in San Francisco a few weeks ago (recognize the voice?). It’s a small slice of the future of entertainment and content. If you believe that culture in the digital era is the culture of remixing, then deepfake tech has an important part to play in the creation of that culture. 

Deepfakes bring us closer to believable virtual humans

The ability to mimic faces, voices, and emotional expressions is one of the most important steps toward building a believable virtual human that we can actually interact with. We’re already taking tentative steps down the path to virtual humans. Personal assistants like Alexa, Siri, and Cortana have been around for several years, reached a tipping point of consumer use, and are quickly improving. Having said that, in 2019 they still feel more like a new user interface you have to pass precise instructions to rather than a virtual being you can interact with. Think a command line operated by speech. 

Virtual humans are entering the mainstream in a different way: Through the recent wave of digital influencers. I previously wrote about this trend in the context of animation history, but digital influencers are also meaningful in the context of believable virtual humans. Digital influencers operate on the same planes of interaction — think your Instagrams and Pinterests — that most people do.

As such, you and I can comment on a Lil Miquela post or message Astro. This is interaction with a being that isn’t real. The digital influencer isn’t really responding to you in their own words — their content is created by storytellers, much as Pixar films have writers. But these digital influencers are laying the social groundwork for interaction with true virtual beings.

Deepfakes have the potential to plug the technological holes in smart assistants and digital influencers. Pushing Alexa or Lil Miquela to the level of virtual humans like Samantha from Her or Joi from Bladerunner 2049 requires the capacity to encompass and express human body language, speech, and emotion. If we counted the number of unique combinations of pose, vocal nuance, and facial expressions you’ve made in your lifetime, it would likely number in the billions. For virtual humans to be believable, their actions can’t be preprogrammed in a traditional hard-coded sense, but must instead be extremely flexible.

Deepfake tech typically takes tons of examples of human behavior as inputs and then produces outputs that approximate or elaborate on that behavior. It could grant smart assistants the capacity to understand and originate conversation with much more sophistication. Similarly, digital influencers could develop the ability to visually react in a believable way in real time, thanks to deepfake tech. Bringing Mickey Mouse to life beyond a Disney cartoon or guy in a suit at Disneyland is where we’re headed. 3D hologram projections of animated characters (and real people) that are able to speak in a realistic sounding voice, moving like their real world counterpart would. 

Creativity starts with copying. Elaboration follows duplication. It is no different with deepfakes, which will democratize access to creativity tools in entertainment, enable entirely new forms of content, and bring us closer to believable digital humans. That is why I think there is as much reason to be excited about the technology’s virtues as there is to be concerned about its vices.
