Bridge systématise le drag and drop entre appareils fixes et mobiles


drag and drop

Une technique systématisée de drag and drop entre appareils mobiles et fixes permet de maximiser au mieux les caractéristiques des outils informatiques : intuitivité et puissance d'exploitation.
L'équipe internationale de chercheurs est ainsi partie de quelques exemples triviaux et quotidiens dans l'utilisation de nos appareils. Comme ils le mettent en avant, il est ainsi facile de prendre une photo avec un smartphone, mais pour l'intégrer dans un document de travail, la puissance de l'ordinateur est requise. Si les systèmes de transferts de données existent bien, ceux-ci sont peu utilisés dans ce type d'échanges légers. Plutôt que de passer par le Cloud, un utilisateur préférera retaper sur son ordinateur une adresse reçue pour en chercher l'itinéraire, par exemple. Dès lors, pour améliorer connectivité entre appareils et fluidité de l'échange d'informations, l'équipe germano-anglaise a conçu un prototype de logiciel permettant un drag and drop entre appareils fixes et mobiles. Pour cela, il est nécessaire de télécharger à la fois sur l’appareil mobile et sur l’ordinateur fixe utilisés l’application Bridge. Une fois l’application lancée simultanément sur l'ordinateur et sur le mobile, celle-ci fait apparaître sur l'ordinateur une fenêtre de détection sur les côtés de l'écran grâce au réseau sans fil. Lorsque l'utilisateur fait le geste de prendre des données et sort de l'écran, l'ordinateur détecte le smartphone ou la tablette proche et envoie les données, et de même de smartphone vers ordinateur. Ce système donne ainsi à l'utilisateur l'impression d'une réelle continuité entre ses différents appareils.

Une information, plusieurs applications

Si cette application devrait devenir de plus en plus répandue sur nos différents appareils au fil du développement du tactile dans les ordinateurs fixes et portables, il semble que l'intérêt premier de cette application Bridge tient avant tout à l'utilisation de l'information. Les chercheurs avancent ainsi avoir voulu permettre, grâce à ce prototype, non plus seulement de partager les données entre appareils, mais de faciliter la mutation de ces données. Une adresse ou un numéro de téléphone reçu sur un smartphone pourraient ainsi être extrait par l'ordinateur de manière automatique et intégrés par exemple aussi bien au carnet d'adresse qu'à un contact de réseau social ou a un document de travail. En facilitant ainsi le transfert de données entre appareils il s'agit surtout d'abord de proposer un format commun et exploitable. Ordinateur et smartphone seraient ainsi à même de reconnaître l'information au sens large et non pas l'utilisation impliquée par le format, permettant de cette façon une utilisation multiple, protéiforme de ces mêmes données via différentes applications.

Why I Lost Faith In Bitcoin As A Money Transfer Protocol

As 2013 came to an end, many reflected on last year’s biggest tech news — and Bitcoin was a serious contender. But the main question remains: why are people interested in Bitcoin?

This whole debate reappeared when Charlie Stross stated that “Bitcoin looks like it was designed as a weapon intended to damage central banking and money issuing banks, with a Libertarian political agenda in mind — to damage states ability to collect tax and monitor their citizens financial transactions.” Paul Krugman then quoted his post, neither denying nor approving this thought.
But Chris Dixon (and Fred Wilson in the comment section) reiterated their strong interest in Bitcoin while sharing that they are both Democrats.
If major Bitcoin enthusiasts don’t have any political agenda in mind, then what is the future of Bitcoin? At its heart, Bitcoin is a cryptocurrency that doesn’t rely on any central bank. Bitcoins are just a chain of characters defined by algorithmic rules, and transactions are handled by the network of miners.
Yet, in a month’s time, the value of a bitcoin went from $200 to more than $1,000 on all the exchanges. In other words, it is as volatile as it can get. Right now, there are only around 12 million of bitcoins in circulation, and many Bitcoin holders are recent converts that buy and sell every day. So how could you think about using bitcoins to pay the rent? You could simply hold your bitcoins and expect to triple your wallet value in a couple of weeks instead.
That’s why I believe Bitcoin isn’t the next world currency. Bitcoin’s true purpose is not what everyone originally expected — you won’t buy a pizza in bitcoins anytime soon. Moreover, Bitcoin won’t be able to remain an unregulated currency for long.
So Bitcoin’s true purpose lies somewhere else. As Bitcoin is a peer-to-peer payment network, you don’t need any banking institution to make large transfers. Bitcoin could become the first meta-currency that sits on top of traditional currencies, the common language between USD and EUR. That’s what Dixon finds interesting, Bitcoin is as much a money transfer protocol as a currency. And it has the potential of disrupting the traditional banking system.

Replacing Forex Transactions With Bitcoin

As I live in France and work for an American company, I thought I would be the perfect candidate for this particular use case. I tried to use Bitcoin to transfer a small amount of money between the U.S. and France. At first, I purchased bitcoins using Coinbaseand my U.S. bank account (a couple of dollars in fees). The process was very easy, but because I don’t meet the requirements to make instant purchases, I had to wait about a week before I could actually do anything with my bitcoins. Coinbase had to verify the transaction first.
While I take Coinbase as an example here, there aren’t many trustworthy and easy-to-use services to make Bitcoin transactions yet — and all services have flaws. People ask me all the time how they could buy bitcoins, and I don’t have a simple answer.
In that period of time, bitcoins went from about $850 a bitcoin to more than $1,000, then back to $700 — I only could sit back and enjoy the ride. Then, when I finally got my bitcoins, I transfered them to Bitstamp in a couple of hours (no fee) — it was flawless and a great example of the beauty of Bitcoin. Finally, I transfered my bitcoins to my French account ($1.24 fee to convert into EUR with a very good conversion rate). I had to wait a few days before getting my money because of the traditional banking system.
Overall, it was a painful experience, even more painful than using traditional foreign exchange services. But more importantly, I don’t see how I could trust Bitcoin as a money transfer protocol with such a high volatility. Fees were much lower, but it doesn’t matter if you don’t know how much money you will get on your bank account in the end.
A couple of weeks ago, Bitcoin’s value went from more than $1,100 to around $650 in a few hours, because of a new rule in China. You can’t use Bitcoin for serious amounts of money if there is a chance of losing 40 percent of your money overnight.
As long as Bitcoin remains a young and volatile currency, Bitcoin’s mechanisms will remain beautiful on paper. Using it for real world transactions would be crazy, and I think we are still a couple of years away from getting a stable Bitcoin that can be trusted. Until then, using Bitcoin will remain a wild ride — it’s definitely fun, but don’t take Bitcoin seriously just yet.

Brassards connectés : Les brassards électroniques accélèrent la prise en charge des victimes d’accidents


Lors d’une catastrophe majeure, la durée d’intervention des premiers secours est souvent critiquée. L’utilisation de brassard électronique et non papier pourrait faciliter ces interventions.


brassardLa première mission des équipes d’intervention médicale, dans le cas d’un accident ou d’une catastrophe naturelle, est de classer les victimes en fonction de la sévérité de leurs blessures.  Ce « triage » s’effectue actuellement au moyen d’étiquettes colorées sur lesquelles les soignants inscrivent, à la main, le pouls ainsi que le rythme respiratoire de la victime. Or, bien que très utile, cette technique de saisie manuelle ne permet pas de mettre à jour les informations et les étiquettes résistent mal aux caprices climatiques. Les chercheurs de l’institut de Fraunhofer pour la technologie de l’information appliquée (FIT) sont donc en train de développer un système de e-triage permettant de localiser les blessés et de transmettre, en temps réel, leurs constantes vitales à un centre de contrôle. A la place des étiquettes, ce sont des brassards en plastique lumineux qui informent de l’état de santé des blessés.

Un projet ambitieux

C’est à la suite de ce constat que, le projet « Bridge »  a vu le jour en avril 2011. Son objectif est d’améliorer les soins médicaux en optimisant la gestion des secours ainsi que l’efficacité des équipes médicales durant les catastrophes. Car en effet la communication entre les différentes équipes d’intervention médicale sur place est primordiale : plus la coordination est fluide, plus le nombre de victimes sauvées sera important. Pour cela, les brassard lumineux comportent notamment un capteur GPS, une puce RFID ainsi qu’un composant permettant de communiquer avec le système informatique central. Les informations peuvent ainsi être transmises par un réseau radio baptisé ZigBee mais aussi par l’intermédiaire du réseau local sans fil ou encore du réseau cellulaire. Les données sont ensuite présentées sur une tablette ou un smartphone et permettent alors aux coordinateurs des opérations d’avoir une vision précise de la situation au sol. Les sauveteurs peuvent alors agir en toute connaissance de cause et prendre les décisions qui s’imposent.

Des résultats engageants

« Avec ce système de e-triage, une personne grièvement blessée classée dans la catégorie rouge est recensée dans les 30 secondes et peut être évacuée immédiatement. Avec la méthode classique, d’étiquettes en papier, il faut souvent 30 minutes pour que la victime soit évacuée » précise Erion Elmasllari, scientifique au FIT. Les chercheurs ont par ailleurs déjà pu tester la fiabilité de ce système, en octobre dernier, au cours d’une simulation d’attaque terroriste en Norvège où le e-triage aurait parfaitement fonctionné. Le prochain test se déroulera, durant deux mois, au sein d’une organisation humanitaire. Les chercheurs devront alors démontrer que le e-triage permet réellement de sauver plus de vies humaines.

A Google Glass-style display add-on for motorbike helmets : Ride:HUD

The Internet of Things is gradually transforming households into smart spaces and we’ve even previously seen the same concept applied to vehicles, with models such as the Xkuty scooter enabling owners to take advantage of smartphone control. However, separate devices can take drivers’ attention from the road. That’s where the NUVIZ Ride:HUD comes in, offering a head up display that overlays pertinent, real-time data onto motorcycle riders’ helmet visors.
Developed through a collaboration between HOLOEYE Systems and APX Labs, the innovation uses technology similar to Google Glass, whereby a small transparent display is located in the user’s peripheral vision. The NUVIS Ride:HUD itself clips onto the chinstrap of any motorcycle helmet and syncs with the rider’s smartphone. The display is controlled through a companion app, which offers the capability of showing GPS-enabled maps and directions, local weather and driving stats such as speed and distance. The HUD can also show who’s calling and what music is playing, as well as toggling between photo and video capture. Rather than refocus their attention away from the road to access this information, the device is calibrated to allow riders to keep the road in their vision. The video below shows the device in action:
The Ride:HUD does have some competition from Skully Helmets, a company currently beta testing its own motorcycle HUDs, but NUVIZ could beat it to the market through its current Kickstarter, which it is using to launch the Ride:HUD. The device can be secured with a backing of USD 499 or more. Are there ways that similar HUD technology could be developed for vehicle drivers of all kinds?

As Software Eats The World, Non-Tech Corporations Are Eating Startups

Netscape founder and VC titan Marc Andreessen famously wrote back in 2011 that software is steadily eating the world, disrupting industries like music, retail and more. Now large corporations in these industries are starting to eat startups.
Over the past year or two, non-tech corporations have begun to actually open their wallets to arm themselves with talent and technology that can help them enter the digital and data-focused world we now live and work in. It’s no longer Google, Facebook and Yahoo that are competing to acquire the best and the brightest startups in Silicon Valley. There are plenty of corporations in retail, health, agriculture, financial services and other industries that are sending their corp-dev talent to scout out possible acquisitions in the Bay Area and beyond.
Let’s take a look at some of the examples. Earlier this year, Monsanto, a multinational chemical, and agricultural biotechnology corporation, bought big data weather tech company Climate Corporation for $1.1 billion. Insurer UnitedHealth Group bought health data analytics company Humedica for hundreds of millions of dollars. A few weeks ago, fitness clothing retailer Under Armour bought fitness tracking app developer MapMyFitness for $150 million. Office supply retailer Staples bought e-commerce personalization company Runa. Payments processing giant First Data has acquired mobile loyalty startup Perka and mobile payments startup Clover in the past year. Retail giant Target has picked up a number of e-commerce companies. Ford Motors bought in-car music app startup Livio. The list goes on.
Their main motivation is realizing that software is eating the world.
Exitround, the website that launched earlier this year and lets startups anonymously seek acquirers, has been seeing a strong uptick in non-tech, corporate acquirers joining the marketplace to find potential talent and startups.
“Their main motivation is realizing that software is eating the world, and they have to add software talent and technologies to their products,” explained Exitround founderJacob Mullins. On the marketplace, Mullins says that 10 percent of buyers are Fortune 500 companies and 20 percent of acquirers are publicly traded, with a good percentage of the group being non-tech companies.
For many non-tech companies, Exitround is providing a compelling service by which to find startups early. Mullins says that there are increasingly more and more corp-dev execs joining the marketplace to scout for talent. But traditionally the mechanism by which acquirers found acquirees was done either through word of mouth and networking or through investment banks. But Silicon Valley is seeing more and more executives from corporations and non-tech companies visit the region and VC firms to potentially network with startups. Many Sand Hill VC firms are now holding regular events with representatives from some of these non-tech acquirers in the areas of health, retail, financial services and more.
“Walmart was the earliest traditional non-tech company to figure this out,” says Jon Sakoda, NEA Partner and VC. Walmart famously bought Kosmix in 2011 and set up a Labs group in Silicon Valley, far away from the retailer’s Arkansas headquarters. The retailer has steadily acquired more companies and technologies in its fight to compete with Amazon, including four startups this year alone.
Aileen Lee, founder of Cowboy Ventures and Partner at Kleiner Perkins, believes that retail will continue to be an industry where you are seeing large companies eat software.
“A lot of physical retailers saw soft foot traffic in their stores in Q3 and they are more nervous about how e-commerce is eating into their sales,” she explains. Companies like TJ Maxx, Urban Outfitters and others can easily make a $100 million to $400 million acquisition in the current market, she adds. In fact, earlier this year, Urban Outfittersreportedly did try to buy NastyGal, a fast-growing e-commerce site for young women.
“Lots of these retailers have no commerce strategy, but startups have the potential to expand consumer reach to a younger demographic,” says Lee.
David Blumenfeld, SVP of Westfield Labs, the innovation arm of shopping mall developer Westfield, tells us that the company is definitely evaluating potential acquisitions that they can bring into their Labs groups.
“While Westfield itself is not a tech company, we believe that there is not a delineation between online and offline shopping, and we have to be a part of that,” he says. “We believe tech is core to the future of how products are bought even in malls.”
He adds that with the company’s malls, they have the distribution (to potentially 1.1 billion people, he says), and they are actively looking for technologies they can integrate into their malls.
Hunter Walk, the co-founder of VC firm Homebrew, explains that developing a deeper relationship with the customer online is a strategy that more corporations realize they need to be working on. Part of this is actually being able to connect with a potential customer where they are interacting and spending time. “Movie theaters have no idea what their customers are watching at home, and there is no personalization,” he says. He adds that he sees many of these acquisitions being under $200 million.
It shouldn’t be surprising that a mattress company may buy a sleep app.
In Under Armour’s case, the company didn’t have much of a direct relationship with the customer beyond purchase. And as a wholesaler, the clothing manufacturer needed a better way to engage with their customers. MapMyFitness is now going to be the foundation on which it plans to build a new digital training experience and mobile fitness platform.
The other benefit to buying platforms where there is engagement is the data collected, which can help potentially boost sales and personalize experiences. “It shouldn’t be surprising that a mattress company may buy a sleep app,” Lee says.
Sakoda agrees that data, and the technologies behind mining this data, are big tipping points for acquisitions from non-tech companies. “These companies have fallen so far behind when it comes to data collection and analysis and seeing how customers think and what pricing should be,” he adds. In the case of Monsanto buying Climate Corporation, the large agricultural giant was accessing massive weather data processing and collecting technology that could help in optimizing farming globally.
“Big companies are finally waking up to fact that they needed to embrace big data yesterday,” says Zach Bogue, the founder of Data Collective, a fund devoted to backing startups in the big data space. “Now every single large company has massive amounts of data, and figuring out how to use that is complex.” This is why many non-tech companies are sniffing around big data startups.
Data is a key area for content owners and publishers as well. Barin Nahvi, who works with emerging tech and new product development at Hearst Corp., says the company is looking to make more acquisitions in core technologies around data. “We’re thinking about how do we resemble a technology company more, and part of this is building platform and core capabilities,” she explains. “How to use data as a driver of content is something we are evaluating.”
Big companies are finally waking up to fact that they needed to embrace big data yesterday.
Nahvi says that video technologies and mobile are other key areas for a potential strategic acquisition for Hearst. E.W. Scripps, the storied owner of 19 local television stations and daily newspapers in 13 markets across the U.S., just bought Newsy to give the media company access to an audience that consumes their news (and video) on devices like tablets.
Of course buying startups in Silicon Valley is just one part of the challenge for non-tech corporations. The next is actually being able to keep talent happy. The cultures of these companies are vastly different from Google, Facebook and the startup culture in Silicon Valley. The true test is being able to retain talent and ensure that they feel they are part of an innovative team.
To that point, many of these companies have created “Labs” groups to house these acquisitions. As mentioned above, Walmart founded its own Labs group,WalmartLabs – which has grown to over 1,200 engineers and staff – when it acquired Kosmix. Live music giant Live Nation, which just bought mobile startup Meexo and acquired two others in the past year, has also set up a Labs group for technology acquisitions.
Walk explains that these companies are not just buying technologies, but also talent, and they have to be mindful of how to manage and foster that talent. “Just adding small pieces of technology doesn’t commit an organization to a new path,” he says. Adding to that, Halle Tecco, founder of health-focused seed fund Rock Health, says that many challenges come from not being able to actually deploy the technologies successfully.
Just adding small pieces of technology doesn’t commit an organization to a new path.
Ethan Kaplan, the VP of product and technology for Live Nation Labs, explains that the labs group was created to house technical talent and acquisitions. He says that the labs group itself was structured to make it feel like less of a conglomerate and more of a startup. There isn’t a deep hierarchy, and Kaplan and others at the group have worked to make the engineers and other staff feel unencumbered, fast-paced and not beholden to a strict road map.
Mullins says that retaining talent is now at the top of mind for most non-tech acquirers. “Most of these companies want to make sure the transition is successful and are talking with potential acquirees early on where a startup will live and who will own the technology once it is placed in-house.”
At the end of the day, non-tech companies infiltrating Silicon Valley gives many startup founders additional exit options beyond a potential acq-hire from Google, Yahoo or Facebook. But the continued success of these acquisitions (and founder interest in being acquired by an outsider) will depend on how these companies pursue and view innovation and culture. And that’s easier said than done.
