Volumetric Displays: How was born 3D

Screenless displays that provide 3-D images viewable from all directions continue to undergo development on multiple fronts. But can they find a market?

In the opening scene of the 2003 movie Paycheck, we learn that the protagonist, Michael Jennings, has been tasked with reverse engineering a screen-based 3-D display made by his client’s competitors. The client’s executives are unimpressed—until Jennings pulls the bezel away to reveal a free-standing 3-D image that no longer needs a screen. The chiefs rejoice: “And they said 100 percent market share was impossible!”

Volumetric display market size

The global volumetric display market is segmented by display type into swept volume and display volume; by component into projector, mirror, lens, memory and screen; by technology into digital light processing and liquid crystal Silicon; by end-user into education, healthcare, aerospace, advertisement and others. The global volumetric display market is anticipated to record a CAGR of 32% over the forecast period i.e. 2019-2027.

Unknown to the viewers, the key transformation at work in the scene—the one that made the display so much more compelling—was the transformation of a traditional 3-D image into a volumetric image. Traditional 3-D uses a screen of some sort to converge light to an optical real image point somewhere in front of the screen. In a volumetric display, the “screen” is, in a sense, scattered throughout the image volume itself: light diverges from scattering or emissive point primitives within the volume to form the image in physical space.

Volumetric images possess a physicality that allows them to occupy space, much like the physical object being depicted.

Thus, rather than converging from a limited aperture, light from a volumetric display may instead diverge over very large angles. In fact, by emitting light isotropically, a volumetric image point can be seen from all directions. By turning convergence into divergence at the modulation surface or surfaces of the display, a volumetric system turns traditional 3-D inside-out, to create screenless real images that place no limitations on the viewer’s position. The resulting images possess a unique physicality that allows them to occupy space, in a way very much like the physical object being depicted.

This article offers a look at the main types of volumetric displays, and some recent advances in this unusual 3-D visualization technology. It also explores some efforts at commercialization—and what advances might be necessary to bring these displays into the mainstream.

3-D display families

To understand volumetric displays, we need to place them in the context of the three families of 3-D displays: ray displays, wave displays and point displays. Both ray and wave displays use a screen as a modulating surface. Ray displays, which include lenticular, barrier-line and some coded-aperture systems, form real points made by intersecting rays in space; wave displays, which include holographic displays and nanophotonic phased arrays, form similar points by focusing a wave front. (Some would argue that these families lie at different places on the same spectrum. We would add that you can determine which side of this spectrum you are on by simply asking, “does diffraction work for me or against me as display elements get small?”)

Separate from these first two families is the third group, point displays, which do not converge light from a surface but instead diverge light from a point. This display family has only one member, the volumetric display. Indeed, the definitions of the point display and the volumetric display are essentially synonymous: the display’s scatterers or emitters are co-located with the actual image points.

The primary result of this co-location is that, in the ideal case, the image may be seen from almost any direction. There is no display aperture (screen), and there may be little or no viewing zone restriction. Co-location of the display emitters with the image points also means that the human eye also accommodates readily to the volumetric 3-D image.

Once a scattering surface is dislocated from the image point it forms (such as when light scatters from a remote screen), however, an aperture is immediately formed that places restrictions on the viewer, and the accommodation cues are now no longer perfect, as they are subject to the diffraction limit of the new aperture. Thus, once the co-location condition is violated, the principal benefits of volumetric displays—perfect accommodation, no view zone restriction—start to diminish. Indeed, Curtis Broadbent, a prominent volumetric-display designer, suggests that once co-location is violated, it’s a clue that we are no longer looking at a volumetric display. “The imposition of limitations on the viewer,” Broadbent says, “violates the spirit of volumetric displays.”

Advantages and disadvantages

The point, wave and ray display taxonomy allows the display designer to identify what type of display she is looking at, and what design challenges are likely to beset a given architecture. The co-location of perceived points with their true sources in volumetric displays in particular creates a powerful and practical discriminant, allowing one to group displays that have similar affordances (that is, similar baseline properties that determine how the viewer can interact with the display) and to evaluate borderline cases. Four affordances in particular highlight the advantages and disadvantages of volumetric displays relative to ray and wave displays.

Human eyes accommodate to volumetric image points just as they do to actual material objects, because volumetric image points are material objects—at least for a brief moment.

Accommodation. Human eyes accommodate to volumetric image points just as they do to actual material objects, because volumetric image points are material objects—at least for a brief moment. However, ray and wave displays form optical real image points by the convergence of light. The quality of that point, or point spread function, depends strongly on the size and quality of the aperture that supports it. Is it coherent? Does it present a large numerical aperture? To match the accommodation of a volumetric point, a ray or wave display would have to completely surround the point, converging from all directions to form the image. Only then could the display aperture be prevented from degrading the accommodative effect.

View angle. The supremacy of volumetric displays also shows in their large view angle, which generally comes “for free” in volumetric displays. Wide view angle in ray displays and especially in holographic wave displays, in contrast, comes at the price of tremendous hardware and computational complexity.

Occlusion. On the other side of the ledger, occlusion—the ability of one object in a 3-D scene to partly obscure another—presents a considerable challenge for point/volumetric images. In general, the image point primitive wants to emit isotropically, but to create images with self-occlusion, it must be possible to turn off the point’s emission in some directions. In ray and wave displays, achieving occlusion is a much simpler matter that generally boils down to careful content creation.

Virtual-image formation. A virtual image can be thought of as a window into another world, which may have no mapping on reality, and it likewise presents challenges for volumetric displays. If a display is hanging on a solid brick wall, but the 3-D image shows an open landscape in the background, it may be necessary to create wave fronts or rays that back-cast to points that cannot exist in real space. Given the requirement that volumetric displays have physical scatterers or emitters co-located with image points, virtual images would seem to be fundamentally impossible for volumetric displays.

An array of tiny emitters that acts like a phased array, or even like Huygens sources, might be made to create virtual image points. But such a display would create an aperture (the array boundaries) that would limit the viewable angles of the virtual image point. It would cease to be a volumetric display and instead become a phased-array wave display formed with volumetric hardware. It would thus inherit the affordances, and challenges, of the wave display family at the expense of the advantages of the volumetric-display family.

(Sometimes that tradeoff is desirable. For example, in the late 2000s, Oliver Cossairt and colleagues converted a volumetric display into a multiview ray display, trading away co-location to obtain occlusion cues.)

Volumetric-display types

Volumetric displays encompass three distinct approaches. Swept-volume displays commonly use rotating emissive or reflective screens, including illuminated spinning paddles, spinning LEDs or translating projection surfaces. As an example, the Peritron display uses a phosphor-coated paddle that spins inside a glass chamber under vacuum. An electron beam hitting the paddle creates a point emitting visible light. Steering the electron beam and spinning the paddle creates a volumetric image from the emissive points.

Static-volume displays might form images by upconversion in nonlinear gases or solids or by projecting onto a number of diffusing planes. The Rochester Illumyn, for instance, is a glass chamber filled with heated cesium vapor. A 3-D position within that gas is illuminated with two beams at wavelengths (such as infrared) not visible to the human eye. The two wavelengths combine in the nonlinear material to form visible light that scatters from that position to form an emissive image point; scanning the two beams creates a volumetric image.

A third, relatively young category, free-space displays, operate in air, with no barrier between user and image; these can include free-particle, trapped-particle and plasma emission displays. The first free-space display known to the authors is Ken Perlin’s “Holodust” concept, in which ubiquitous dust motes are identified and then immediately illuminated with a laser to build an image in space. Later, the University of Keio demonstrated a display in which a powerful, pulsed IR laser is focused in air to create a plasma. Scanning the focus through the air draws an image composed of plasma dots. This process has been refined to use femtosecond pulses and a spatial light modulator to focus to multiple points simultaneously. Several displays use heat or fog to modify air so that it can scatter or modulate light.

This year saw the introduction, at Brigham Young University, USA, of another free-space display, the optical-trap display (OTD). An OTD operates by first confining a light-scattering particle in a nearly invisible optical trap. The trap is moved through space, dragging the trapped particle with it. The trapped particle is then illuminated with visible lasers to draw a 3-D image by persistence of vision. The prototype scans particles at roughly 1 to 2 m/s to form very small (1 cm3) video-rate images. These small images can be full-color and possess image definition up to 1600 dpi. Researchers hope to greatly increase the size of images in future prototypes by using multiple particles simultaneously.

In addition to the examples above, the volumetric-display scene includes several borderline cases, which often use volumetric hardware to produce a ray display (or vice versa). For example, the Texas DMD display, commonly called a holographic display, is perhaps better classified as a volumetric display. That’s because the focus of the holographic wave fronts from the DMD focus inside a diffusing liquid, which provides a scattering medium that enlarges the view zone of the display—and in so doing trades away the ability to occlude points. Holographic hardware thus creates a volumetric display, and thereby adopts the advantages and disadvantages of its new display family.

Another borderline example, the Sony Raymodeler, uses a spinning array of LEDs and thus appears superficially similar to swept-volume displays. However, these LEDs are not used as point primitives; instead the array projects a large number of views as a ray display. As such, the display can easily achieve occlusion and can create virtual images, but lacks the perfect accommodation of a volumetric display.

Efforts at commercialization

Despite the bullish forecast of the executives in Paycheck, volumetric displays haven’t exactly captured 100 percent of the 3-D display market. There have, however, been a number of commercial efforts. Two case studies hold particular interest: Actuality Systems’ Perspecta Display, a 10-cm-diameter swept-volume display, and the LightSpace DepthCube, a stacked-LCD static-volume display. Despite the displays’ physical differences, the teams behind them came to similar conclusions at the end of years-long commercialization efforts.

Actuality Systems

Gregg Favalora, the Harvard-educated founder and CTO at Actuality Systems, made his first attempt at a volumetric display in 1988 as a ninth-grader. He would later make volumetric images because he felt that a “floating 3-D image would be visually impressive, and in 1997-2000 seemed so feasible” owing to emerging technologies. Favalora noted the availability of Texas Instruments micromirrors and computational resources to do rendering. He had also identified a way (an aspect of which had been proposed in the 1950s) to project a sharp image onto a spinning disk.

Encouraged by money won in an MIT entrepreneurship competition to build a company, Favalora founded and raised seed funding for Actuality Systems at the turn of the 21st century. Its flagship display, the Perspecta, was capable of images with remarkably high resolution. Perspecta could generate a 100-million-voxel image with off-the-shelf—albeit expensive—parts. The display was marketed to a wide variety of potential customers as a tool for user-interface research, structure-based pharmaceutical design and petroleum exploration, and was assessed in medical visualization. The technology’s high price point, however, constrained the customer base, and Actuality Systems’ assets, such as its valuable patent portfolio, were acquired by Optics for Hire in 2009.

LightSpace Technologies

During the same period, on the other side of the country, Alan Sullivan was building a 100-TW laser at Lawrence Livermore National Laboratory. Looking for a new opportunity, he came upon a startup that included, in his words, an “empty room, a sketch on a napkin and more or less a blank check” to develop 3-D displays. Sullivan jumped on board. The following years brought reorganizations and promotions, and Sullivan, now CTO, had shepherded the start-up’s static-volume prototype to a pre-commercial state. Now in 2003, all they needed was a market.

Unfortunately, the search for a market outlived two companies, the second of which, LightSpace Technologies, Sullivan founded himself. Despite the display’s high price—more than US$10,000—there were a number of interested parties. But all made demands that the display could not meet. There was interest from the medical field, but the display needed to be entirely free of artifacts. Slot machine manufacturers loved it, but they needed it to be extremely inexpensive (say, US$50 per unit). The oil industry was keen, but it needed a much larger display for large-group collaborative decision-making. After years of searching, Sullivan thought he might have found a niche market in interventional radiology, but it was deemed too small a market by his investors.

By 2007, Sullivan had reached a state he describes as “total exhaustion” and left LightSpace. Before leaving, he submitted a 200-page document full of suggestions for improvements to the display. The recommendations reportedly all turned out to be good ideas, and recently the LightSpace DepthCube has resurfaced with an improved display.

The similarity between the Actuality and LightSpace commercialization efforts seems to be that, despite excellent technology, success appears to require a dramatically reduced price point, greater size or still greater image quality. It will be interesting to see if the new LightSpace display and the new swept-volume Voxon Photonics VX1 can lower cost and increase affordances enough to gain a market foothold. Also of interest will be the rise of the Rochester rubidium-cesium excited-gas display, which might achieve display diameters of more than a meter, according to one of its inventors, Curtis Broadbent. Free-space displays have also made forays into the commercial sphere, including Burton Aerial in 2011 and a Kickstarter effort launched in 2016 by Jaime-Ruiz Avila.

Killer app wanted for Volumetric Displays

These early commercialization experiences, and an assessment of the features of current and future volumetric displays, prompt the question: What is the “killer app” for volumetric displays? Does there exist an application that only a volumetric display can adequately accomplish? Or could every potential application be done, and done more cheaply, with another display—such as, for example, a head-mounted display?

Notwithstanding the current efforts of AR/VR juggernauts, we believe that the answer to this question is no in at least some cases: When one wants to look someone else in the eye who is remotely located; when you can’t reasonably put glasses on your intended viewer (such as an enemy combatant, or everyone who might pass by your storefront); or when one set of headwear might conflict with another headset used in medical or military applications.

In these scenarios, the materiality of volumetric displays—their presence in space, and the freedom from restrictions on the viewer’s location—makes them an ideal choice. The case for these displays is also strengthened if the imagery is sparse, viewed at interactive distances, or created in concert with other technologies, like holography, with complementary affordances.

The 3-D displays most typically imagined in our popular depictions of the future, in books and in films such as Star Wars and Paycheck, tend to most resemble free-space volumetric displays—in particular, OTDs. These displays have the potential to provide both excellent color and fine detail. However, it is too early to say if this technology will provide a feasible platform for 3-D display, as OTDs still have some significant technical challenges to surmount.

If angular control is achieved, then viewer-customized imagery should not be too far behind.

First, the OTD demonstrations thus far have involved trapping, illuminating and scanning a single particle, and it remains to be shown that several particles can be trapped and illuminated simultaneously in a reliable and robust fashion. If this can be accomplished, however, it’s interesting to envision the new possibilities that a colorful, detailed free-space platform might provide. For example, one might be able to obtain large autostereoscopic 3-D images from small devices—mobile-technology analogs of Princess Leia’s image in Star Wars.

If OTDs could be made to scatter selectively in preferred directions (an even greater challenge than multiple-particle manipulation), it might even be possible to see the first free-space images with self-occlusion. The same directional control could also be used to create an effect that hasn’t previously been much discussed, even in science fiction—that of a viewer-dependent physical image. That is, one could project a volumetric image that would be customized for each individual viewer. If angular control is achieved, then viewer-customized imagery should not be too far behind.

In an era of renewed interest and new possibilities for volumetric displays, it is more important than ever to understand and appreciate their unique place among 3-D technologies—and the technological and commercial breakthroughs that could come in the near future.

How does it compare to Virtual Reality and Augmented Reality?

The biggest difference is the fact that you don’t need to wear a headset. Our technology also enables a unique shared social experience, where people gather around and interact with genuine face to face communication.

How to Use DeepNude Online?

DeepNude is AI software that generates fake nude images of women. It’s floating around the Microsoft-owned code repository GitHub and has been making its way onto Telegram message boards and Telegram channels. But how can you tell if it’s legitimate? How do you find out? It’s easy – follow these steps and you’ll be able to make your own. The downside to DeepNude is that it will destroy the quality of any image.

The creator of DeepNude identified himself only as Alberto and explained that the idea for the app was inspired by comic book advertisements for X-Ray glasses. These ads promised the ability to see through people’s clothes. He continued to experiment out of curiosity and was inspired by old X-Ray-glasses ads. This led him to create his own version of the software, which was called DeepNude.

4 Steps

The software creates a new, naked image of the same person. The only difference is that it only works with pictures of women. It’s best to use images that feature plenty of skin. However, DeepNude works best with pictures of women in sports magazines. The free version has a stamp on the image that says “FAKE” – this makes the images much easier to recognize as fakes. In addition, it’s easy to crop out the watermark or insert your own.

Step 1: Go to the Web App.

Step 2: Upload your photo.

Step 3: Waiting up to 5 min.

Step 4: Check fake pics.

Reasons to Keep Crypto in Mind for Your Business

While the majority of people have heard of Bitcoin, just 10% of them are aware of how cryptocurrencies function, let alone how they came to be. While you don’t need to be an expert on the technology, understanding how cryptocurrencies might assist your small business is vital. Improved workflows, cheaper operational expenses, decreased fraud, and better confidence among vendors and consumers are just a few of the small company benefits of “cryptos.”

As a reminder, cryptocurrencies were created in 2009 as a direct response of the financial crisis of 2008. Years of dubious advertising and usage of financial products including unfunded credit default swaps, subprime home loans, and mortgage-backed securities contributed significantly to the catastrophe. Traditional banks, investment firms, and financial institutions pushed such assets up and down, crashing the US and global economies.

Hundreds of billions of dollars in bailouts and artificial interest rate resets to zero or less were necessary to avoid a catastrophic economic catastrophe, courtesy of central banks all around the world. Those Herculean efforts were made to keep economies afloat and preserve huge banks that were deemed “too big to fail.”

The focus on protecting Wall Street by policymakers and central bankers over Main Street small enterprises and regular investors demonstrated how government budgetary blunders and botched monetary policies may have major geopolitical consequences. We’d all witnessed it, and none of us wanted it to repeat again.

Following this, an alternate monetary model was developed. It was designed to help individuals and give us a fighting chance against Big Banks and Big Finance’s “smart money” and capital limits.

Following the publishing of a white paper introducing Bitcoin and how it would function, cryptocurrencies arose. Cryptocurrencies, which are built on a tamper-proof blockchain to avoid financial nonsense, offer people financial independence and fiscal equality by trading in wallets such as Exodus Bitcoin Wallet.

Cryptocurrencies have a number of advantages, including the elimination of third-party gatekeepers like as banks, fast settlement transaction times, much decreased transaction costs, and low-friction transfers to any location with an Internet connection. Those crypto advantages can be beneficial to almost any small business.

Despite the volatility of cryptocurrencies, the fundamentals that sustain their use case and value remain unchanged. Take a look at these three macroeconomic trends that aren’t likely to go away anytime soon: Governments are continuing to create money at unprecedented levels.

In February 2020, the US Federal Reserve allowed the US Treasury to accelerate the printing of US dollars. Since then, the entire monetary supply (M2) has risen by 31% to $21 trillion in circulation in less than 18 months. It doesn’t take a Nobel Laureate in Economics to see that when money is created and poured into markets in ever-increasing volumes, the value of each individual dollar diminishes.

Stablecoins like USD Coin and Dai, which are tethered to the US dollar, have stayed stable despite the influx of cash into the market. Right now, your unused stablecoins on a cryptocurrency exchange (a desktop or mobile program for buying and selling digital coins/tokens) may generate annual percentage yields of 4 to 12%, which is a good rate of return for any small business.

Inflation is continuing to rise, and the cost of commodities is rising as well.

June’s inflation rate jumped 5.4 percent, according to the US Bureau of Labor Statistics. That was the greatest year-over-year increase in consumer goods prices since 2008. The Consumer Price Index is sometimes criticized as an incorrect measure of “actual inflation” since it is based on cost changes for a basket of goods and services, yet politicians have altered the composition of that basket at random throughout time. It isn’t a reliable criterion.

Despite these shortcomings, the 5.4 percent rise in June 2021, on top of the 5.0 percent increase in May 2021, is difficult to dismiss. Those figures don’t include the double-digit increases in housing prices, used vehicle costs, and gas prices. You’re on the front lines of inflation as a small firm, with few choices for safety. Bitcoin, on the other hand, is a potential inflationary hedge that can readily be bought or traded in fractional quantities for small firms that may require quick access to liquidity because to its scarcity of only 21 million tokens.

DALL·E: Creating Images from Text

Open AI shared the results of their research, which I can not call anything other than magic – DALL · E, a new neuron, a continuation of the GPT-3 idea on transformers, but this time for generating images from text.

I often write here about fantasy, they say, I fed Harry Potter to the neuron and received illustrations of all the scenes of the book – it seems this is no longer a fantasy, but they still don’t give me anything to dig deeper.

DALL · E neuron with 12 billion parameters, trained in picture-text pairs, its tasks:

  • Synthesize pictures by text description
  • Draw pictures with a part at the input, taking into account the text description

Open AI has already teased some things in this area before, and finally it has reached such a level that the jaw is falling off, look at the examples that I have attached, at the top of the text that was given at the input.
I’m sure she won’t be allowed to play for everyone yet.
I foresee this research will greatly affect many areas and industries, as the applications are endless.

This is the client’s paradise: “play with fonts”, “enlarge the logo”, “highlight in red” – all this is readily done by a mentally balanced machine.
On the other hand unusual illustrations for children’s books, for example, are also welcome.

RefaceAI: How to build Affordable deepfake App

In 2019, the Ukrainian IT-company Neocortext (current RefaceAI) released the Doublicat mobile app (now Reface), with which the user can replace the face on the gif with his own. Six months later, the application was already changing faces to video, and by August the number of its installations exceeded 20 million.

According to the analytics service App Annie as of August 15, Reface is among the ten most popular apps on iOS in 15 countries, and on Android – in 19.

How the user interacts with the service?

To insert their face into a GIF or video, the user takes a photo in the application and selects a template, for example, a fragment from a movie. After that, the algorithm changes its appearance in a few seconds. The result can be downloaded immediately or shared on social networks.

How does the technology work and where is it used?

Usually, when creating a deepfake, it takes a lot of time to train a neural network. At the same time, a separate network must be trained for each person.

However, RefaceAI has created a universal Artificial neural network to replace any human face, thanks to which a deepfake is obtained in seconds. The developers have trained the network on millions of images from open libraries (the company does not disclose the name), so it can change faces in both photos and videos.

Having received the user’s photo, the network “translates” it into face embeddings – an anonymized set of numbers. According to it, the machine determines the facial features and transfers them to the template.

Deepfake turns out to be more realistic thanks to machine learning, including a GAN-type neural network – its peculiarity is that it includes two networks that train each other. In the case of Reface, for example, they “adjust” the color of the user’s face to the lighting of the original video or picture.

Startup Success Story

RefaceAI, the company behind Reface, was founded in 2011 by:

  • Roman Mogilny – CEO.
  • Oles Petriv – Technical Director.
  • Yaroslav Boyko – Chief Operating Officer.

Before the face-swapping app, entrepreneurs had been involved in various projects for seven years: developing websites, collaborating with post-production studios for Hollywood films, where machine learning technologies were needed. For example, they converted a video from 2D to 3D format.

In 2018, the company came up with the idea to create an app that would replace faces in photos. At that time, RefaceAI employed six people.

RefaceAI has raised 1 round. This was a Pre-Seed round raised on Dec 5, 2019. Adventures Lab has invested in the startup between $300,000 and $500,000.

In March 2019, Elon Musk posted photos on Twitter with his face instead of Dwayne Johnson’s. The image featured the Reflect watermark. Due to this publication, application traffic has grown tenfold, entrepreneurs noticed.

By September, the co-founders realized that simply changing faces in photos was not enough. At that time, product manager Ivan Altsibeev joined the team. He will suggest switching to gifs. The idea turned into a Doublicat app. It was presented at Product Hunt in January 2020.

According to Mogilny, Petriva and Boyko, Doublicat received about 600 mentions in the media, including Forbes and Mashable.

Six months later, the company added face-to-video to the app and renamed Doublicat to Reface. With the new feature, the service has grown in popularity, with Britney Spears, Snoop Dogg and other celebrities sharing their videos.

Reface currently has 20 million installs and continues to grow. How quickly, the company does not specify. Her spokesperson added that 65% of users share content created in the app.

The basic version of Reface is free. The company receives income from advertising and paid subscriptions, where you can turn off the watermark: 199 rubles per week, 299 rubles per month and 1990 rubles per year. The company does not disclose the total revenue from the service.

To replace faces in photos, developers use images with open licenses, and for gifs they partner with sites like Tenor.

In the case of the video, the company adheres to the advice of lawyers:

  • Content falls under US copyright fair use and therefore does not require licensing.
  • Limits the length of the videos, their quality and the rest of the content.

If the copyright holder wants to exclude their materials from the application, Reface App will remove them.

What’s next?

In an interview Mogilny, Petriv and Boyko explained that the popularity of such applications is usually short-lived, so they use mechanics to retain users.

According to entrepreneurs, Reface will move forward not only the appearance of new content, but also its localization – so that the user can insert his face into a clip with a popular star in the country.

Since 2018, RefaceAI has grown to 40 employees. She is currently conducting closed beta testing of the Reface Studio web platform. With its help, creators of entertainment content will be able to insert faces into any video. In the future, the company plans to replace bodies as well.

As conceived by the founders, the new service will work in the b2b segment as well: it will be useful for creative agencies, filmmakers and computer game developers.

One of the problems that Reface Studio can face is using the service to create fake news and replace the faces of famous people. To prevent possible harm to the public, developers will apply two approaches:

  1. You cannot use the service anonymously.
  2. The video created in the “studio” will have an invisible mark that the project was created using Reface Studio.

Napkin Idea To MVP: Studiotime

One evening in March 2015, Mike Williams set himself a simple rule. The time spent building a fully functional prototype of his marketplace idea should not exceed one evening. “I’m going to cancel dinner plans and instead build the Airbnb for music studios,” he decided.

For a while before, Mike Williams had been paying attention to how his friends in the music industry tried to find, compare, and book music studios. They relied heavily on their networks and sent text messages to find out about available studios, equipment, rates, and so on. He knew there had to be a better way to do it and set out to build it.

Mike did some initial industry research, which revealed that to his surprise, he couldn’t find anyone trying to solve the same problem. That’s when he came up with an ambitious concept: “Studiotime, an Airbnb for music studios.”

As the founder of a few fast-growing marketplace startups, Mike had lots of other obligations and knew that Studiotime would need to be a passion project.

“That’s why I decided I could only spend one evening building it. Even though I had no idea if setting up a fully functional marketplace in one evening would even be possible.”

After deciding to skip the dinner that evening, Mike found Sharetribe. Amazingly, he was able to achieve exactly what he had wanted: his site was up and running the same evening.

On Sunday of the same week, Mike purchased the domain studiotime.io, and minutes later he launched his site by posting it to Product Hunt, an online community for discovering new products.

What happened afterward surprised him completely. It turned out that Product Hunt users loved Mike’s concept.
