Fairy Lights: Hologram-Like 3D Images In The Air That You Can Touch

Published

on

Japanese researchers from the University of Tsukuba, Utsunomiya University, Nagoya Institute of Technology, and the University of Tokyo have developed a “Fairy Lights” display system that creates touchable hologram-like images in midair, IEEE Spectrum reports.

The Fairy Lights display uses lasers pulses fired at high frequency to ionize air molecules in midair, creating bright pixels that float in space and give tactile feedback when touched. Such systems, which have existed for a few years, are produced by companies like Japan-based Aerial Burton. However, the tactile feedback given by “traditional” laser-induced plasma displays is a bit too strong – the floating plasma that they generate will severely burn your fingers if you try to touch it.

The Fairy Lights researchers have solved the problem by using femtosecond lasers with a pulse duration of only a few tens of femtoseconds (one femtosecond is one millionth of one billionth of one second), much shorter than the nanosecond (one billionth of one second) pulses used in previous applications.

Fairy LightsThe User Feels an Impulse on the Finger as if the Light has Physical Substance

The research results are detailed in a paper submitted to ACM Transactions on Graphics. A draft version of the paper, titled “Fairy Lights in Femtoseconds: Aerial and Volumetric Graphics Rendered by Focused Femtosecond Laser Combined with Computational Holographic Fields,” is freely available on arXiv.

“Our system has the unique characteristic that the plasma is touchable,” notes the research paper. “It was found that the contact between plasma and a finger causes a brighter light. This effect can be used as a cue of the contact. One possible control is touch interaction in which floating images change when touched by a user.”

Shock waves are generated by plasma when a user touches the plasma voxels. Then the user feels an impulse on the finger as if the light has physical substance.

Virtual and Augmented Reality systems like the Microsoft HoloLens can display images and 3D holograms floating in virtual air in front of the user, and even give tactile feedback via haptic gloves, but the holograms don’t really exist – they are but pixels generated by a computer device. On the contrary, the Fairy Lights system generates physical pixels that can be touched with the bare fingers.

Touchable laser-induced plasma display technology is very young and the tiny pixels in the images and video are but a first rough demonstrator. However, the researchers envisage future refinements of their technology that could permit creating life-like, high-resolution, touchable 3D displays in the air.

Monero Price Analysis: XMR/USD is Stable and Gunning for Potential Gains on “Bulletproofs” Technology Update Day

Published

on

  • Monero developers have released an updated version to their protocol, implementing “Bulletproofs”.
  • XRM/USD is within a range block, with price behavior suggesting of a potential imminent breakout higher.

Monero Becoming First Crypto Over Billion-Dollar Market Cap Implementing “Bulletproofs”

Developers at the Monero foundation, have released an updated version to the protocol. This will be live from 18th and 19th October. They are becoming the first network to try out “bulletproofs”. The goal of this technology is to significantly decrease the weight of confidential transactions. From today, 18th October, the privacy-focused cryptocurrency will be testing this.

The move from Monero will make them the first crypto with over a billion-dollar market cap, to try out the “bulletproofs” technology. Over the past year, the foundation has been working on cutting the size of its confidential transactions, by at least 80 percent.  A full overview of the upgrade was posted in a blog post by Monero.

The purpose of bulletproofs are to facilitate confidential transactions. Senders and recipients addresses will remain visible, but the amounts being sent is concealed. The technology also aims to reduce transaction times and fees.

Sarang Noether, a spokesperson for Monero and a key part of the bulletproof integration, was recently speaking on the upgrade. He noted that “Bulletproofs will be replacing the “zero-knowledge range proofs”, of which their confidential transactions are reliant on. The cryptocurrency will activate the technology during its next system-wide upgrade, or hard fork. An upgrade that will require nodes to adopt a new software. Furthermore, Sarang added, “hard forks are sometimes colored as a risky process. However, this upgrade is part of Monero’s bi-annual cycle to introduce new features.”

Technical Review – 4-hour Chart

XMR/USD 4-hour chart

XRM/USD for the past going on three sessions now has been trading within a tight range-block. This trading behavior coming after the aggressive movements seen just some days before. On 11th October the price had spiked over 10% lower. To then enter a tight range, which saw a huge breakout, jumping around 20% high. Over half of this spike to the upside was reversed, moving into the three-session range as mentioned above.

Looking to the upside, eyes will be on another range-breakout. Bulls will be wanting to retest the breached supporting trend line. An attempt was made during the rally seen on 15th October, however strong resistance was observed. In terms of support, this can be eyed at the lower part of the current range, around $107.50. If the bears pile enough pressure, it vcould see a fast move back to $100, then further south below demand area from $86-76.

IOTA Price Analysis: Current Behavior Raises Concerns of Another Drop in the Price

Published

on

  • Current technical indications still point to downside risks for IOTA’s MOITA price.
  • Near-term chart view sees a rising wedge pattern. The daily chart observes a bearish pennant formation.

The IOTA price remains at risk for now of a breakout to the downside. It appears more likely that downside pressure will be seen, in comparison to any upside surprises. Despite this, IOTA’s native token has made solid recovery in just over a week of trading. Since 25th September, it has gained 8%. Trending higher has been observed from a low of around $0.5200, up to current levels around $0.5600.

IOTA Developments

Most recently, Bitpanda announced they now offer deposit and withdrawal services for IOTA. Bitpanda is fintech company based in Vienna, Austria. They specialize in selling and buying Bitcoin and other cryptocurrencies. Becoming Europe’s leading retail broker for Bitcoin, Ethereum, Litecoin and more, boasting a user base of over 900,000 users. “We are very pleased to announce not only withdrawal and deposit functionalities for IOTA on Bitpanda, but also that Bitpanda now officially supports the latest IOTA tech — IOTA Hub,” as stated in their most recent blog post.

This move goes to show the growing presence IOTA is having across the market. The market acknowledgement of the foundation’s technology. IOTA’s MOITA is currently the 11th largest cryptocurrency by market cap, which is seen at $1.5 billion.

Elsewhere, as covered previously, the foundation is very close to revolutionizing the car insurance industry. They presented a new project in which they have been working on at bIOTAsphere. This was a proof of concept technology, known as Tangle. Full details mentioned in the previous article.

Near-term Technical Review 

IOT/USD 60-minute chart

Looking via the 60-minute chart, current price action has formed a rising wedge pattern. This price behavior makes it susceptible to a breakout to the downside. Should the bears manage to breach the lower support, sellers could pile in. To the downside, support in this view can be seen tracking around $0.5650. Further to the downside, 60-minute support should come into play around $0.5420.

Daily Chart Technical Review

IOT/USD daily chart

For over a month now, price action, as clearly seen on the daily chart view, has been firmly within consolidation mode. The range is getting tighter, building up the likelihood of an imminent breakout. Resistance is sitting just ahead around $0.5850, very close to current levels. Support eyed at $0.5430, a breakout could see the price tumbling. A potential downside target would likely be around the $0.4000 territory, testing 14th August low.

From Credits to Cryptocurrency: Block-Gaming Here to Stay

Published

on

The relationship between cryptocurrency and video-games is getting stronger with reports this week detailing the launch of a self-proclaimed ‘Blockchain Game Alliance’, a collaborative initiative founded and comprised of a handful of organisations.

These range from the blockchain-focused (such as ConsenSys) to those specialising in video-games (like centralized crowdfunding platform Fig).

The Blockchain Game Alliance is one of the first of its kind to be seen, bearing a simple website which bears a subscription form and self-referential claims of being a

“coalition of gaming and Blockchain companies committed to advocate for the democratization of Blockchain within the gaming industry”.

French games publisher Ubisoft is notably the name that has featured in the greatest number of headlines around describing this event: and there are many reasons for this.

What’s So Special About Ubisoft

Ubisoft is one of the biggest names in the video-game business and is also part of a small, yet growing list of prominent video-game companies which have chosen to dip their toes in the sector (including Nvidia and AMD).

The company has enjoyed a 400% growth in stock value over the past three years, and releases a multitude of blockbuster franchise entries on an annual basis.

Additionally, this week’s news is only the latest in a series of recent stories indicating Ubisoft’s blockchain aspirations such as: a partnership with Google, and the release of a blockchain game entitled ‘HashCraft’.

From Credits to Cryptocurrency

Whilst a far cry from the integer based ‘credits’ system of arcade video-games, fiat-purchased digital currency is (and has remained) an integral part of the games industry ever since.

Original home-console implementations of digital currencies began with the distribution of points and in-game ‘money’ that can be used to buy items within that specific game they are involved in – like power ups and extra lives. This is in parallel to digital implementations of gambling games in casinos and online.

Companies like Ubisoft have implemented and helped to pioneer movements such as micro-transactions (for downloadable content and in-game items). This is alongside ‘games-as-a-service’ models, which often requires subscriptions from players to gain access to content which is creatively updated and added to on a continuous basis.

These examples are centralized, with non-fungible ‘currencies’, and would make prime candidates for ‘tokenization’.

Digital Distribution + Blockchain

Quite arguably the most ubiquitous utilisation of virtual in cryptocurrency in video-games is the digital distribution model.

This is a method of purchasing video-game titles in whole through a virtual marketplace from which they are also downloaded and have been integrated into home-consoles for the most recent two ‘generations.

Beyond Sony and Microsoft’s stores: industry leaders at present include Steam (Valve), Uplay (Ubisoft), and Good Old Games (GOG).

Big Contributions. Small Companies

As proven by the roster behind the Blockchain Gaming Alliance, there is value to be gained from all positive contributions – whether the company specialises in cryptocurrency or video-games.

There is also value to be gained from the contributions of newer organisations which have been formed specifically to catalyse the marriage of blockchain and gaming.

Equiti Games is one such company, hailing itself as a revolutionary approach which will decentralize and tokenise video-games digital distribution. By removing centralized middle-men and platforms taking up to 30% in fees, Equiti Games plans to reduce costs for gamers.

This will be accomplished, according to the company’s website and whitepaper, by using the Ethereum blockchain to connect creators to their customers directly. A maximal proportion of profits will therefore be delivered to the creator whilst a second-hand market is opened up for consumers – making digital products retain their previously transient value.

Terra Virtua is another company which I have mentioned many times due to the pedigree of the executive team as well as their innovative VR-centric approach. They seek to combine two nascent technologies along with video-games, and they have key partnerships with companies like Epic Games (Unreal, Gears of War, Fortnite).

Final Words

So the biggest question which remains to be answered is: what exactly will this ‘Blockchain Game Alliance’ do to blockchain and gaming: both collectively and as separate entities?

Such big actions (and from such large ‘movers’) signals a turning of the tide with ideas that, if implemented, would open up cryptocurrency to a large consumer market and encourage mainstream adoption within and outside of the gaming-sphere.

Other giants in the gaming industry who could benefit the crypto-video game movement significantly include: Activision Blizzard (World of Warcraft, Call of Duty, Overwatch), and console makers such as Sony, Nintendo, and Microsoft.
