Scientists make a touch tablet that rolls and scrolls

Research scientists at Queen’s University’s Human Media Lab have built a prototype touchscreen device that’s neither smartphone nor tablet but kind of both — and more besides. The device, which they’ve christened the MagicScroll, is inspired by ancient (papyrus/paper/parchment) scrolls so it takes a rolled-up, cylindrical form factor — enabled by a flexible 7.5inch touchscreen housed in the casing.

This novel form factor, which they made using 3D printing, means the device can be used like an erstwhile Rolodex (remember those?!) for flipping through on-screen contacts quickly by turning a physical rotary wheel built into the edge of the device. (They’ve actually added one on each end.)

Then, when more information or a deeper dive is required, the user is able to pop the screen out of the casing to expand the visible display real estate. The flexible screen on the prototype has a resolution of 2K. So more mid-tier mobile phone of yore than crisp iPhone Retina display at this nascent stage.

 

 

The scientists also reckon the scroll form factor offers a pleasing ergonomically option for making actual phone calls too, given that a rolled up scroll can sit snugly against the face.

Though they admit their prototype is still rather large at this stage — albeit, that just adds to the delightfully retro feel of the thing, making it come over like a massive mobile phone of the 1980s. Like the classic Motorola 8000X Dynatac of 1984.

While still bulky at this R&D stage, the team argues the cylindrical, flexible screen form factor of their prototype offers advantages by being lightweight and easier to hold with one hand than a traditional tablet device, such as an iPad. And when rolled up they point out it can also fit in a pocket. (Albeit, a large one.)

They also imagine it being used as a dictation device or pointing device, as well as a voice phone. And the prototype includes a camera — which allows the device to be controlled using gestures, similar to Nintendo’s ‘Wiimote’ gesture system.

In another fun twist they’ve added robotic actuators to the rotary wheels so the scroll can physically move or spin in place in various scenarios, such as when it receives a notification. Clocky eat your heart out.

“We were inspired by the design of ancient scrolls because their form allows for a more natural, uninterrupted experience of long visual timelines,” said Roel Vertegaal, professor of human-computer interaction and director of the lab, in a statement.

“Another source of inspiration was the old Rolodex filing systems that were used to store and browse contact cards. The MagicScroll’s scroll wheel allows for infinite scroll action for quick browsing through long lists. Unfolding the scroll is a tangible experience that gives a full screen view of the selected item. Picture browsing through your Instagram timeline, messages or LinkedIn contacts this way!”

“Eventually, our hope is to design the device so that it can even roll into something as small as a pen that you could carry in your shirt pocket,” he added. “More broadly, the MagicScroll project is also allowing us to further examine notions that ‘screens don’t have to be flat’ and ‘anything can become a screen’. Whether it’s a reusable cup made of an interactive screen on which you can select your order before arriving at a coffee-filling kiosk, or a display on your clothes, we’re exploring how objects can become the apps.”

The team has made a video showing the prototype in action (embedded below), and will be presenting the project at the MobileHCI conference on Human-Computer Interaction in Barcelona next month.

While any kind of mobile device resembling the MagicScroll is clearly very, very far off even a sniff of commercialization (especially as these sorts of concept devices have long been teased by mobile device firms’ R&D labs — while the companies keep pumping out identikit rectangles of touch-sensitive glass… ), it’s worth noting that Samsung has been slated to be working on a smartphone with a foldable screen for some years now. And, according to the most recent chatter about this rumor, it might be released next year. Or, well, it still might not.

But whether Samsung’s definition of ‘foldable’ will translate into something as flexibly bendy as the MagicScroll prototype is highly, highly doubtful. A fused clamshell design — where two flat screens could be opened to seamlessly expand them and closed up again to shrink the device footprint for pocketability — seems a much more likely choice for Samsung designers to make, given the obvious commercial challenges of selling a device with a transforming form factor that’s also robust enough to withstand everyday consumer use and abuse.

Add to that, for all the visual fun of these things, it’s not clear that consumers would be inspired to adopt anything so different en masse. Sophisticated (and inevitably) fiddly devices are more likely to appeal to specific niche use cases and user scenarios.

For the mainstream six inches of touch-sensitive (and flat) glass seems to do the trick.

‘Unhackable’ BitFi crypto wallet has been hacked

Posted by | Android, computing, defcon, Gadgets, john mcafee, operating system, spoiler, Startups, tablet computer, TC | No Comments

The BitFi crypto wallet was supposed to be unhackable and none other than famous weirdo John McAfee claimed that the device – essentially an Android-based mini tablet – would withstand any attack. Spoiler alert: it couldn’t.

First, a bit of background. The $120 device launched at the beginning of this month to much fanfare. It consisted of a device that McAfee claimed contained no software or storage and was instead a standalone wallet similar to the Trezor. The website featured a bold claim by McAfee himself, one that would give a normal security researcher pause:

Further, the company offered a bug bounty that seems to be slowly being eroded by outside forces. They asked hackers to pull coins off of a specially prepared $10 wallet, a move that is uncommon in the world of bug bounties. They wrote:

We deposit coins into a Bitfi wallet
If you wish to participate in the bounty program, you will purchase a Bitfi wallet that is preloaded with coins for just an additional $10 (the reason for the charge is because we need to ensure serious inquiries only)
If you successfully extract the coins and empty the wallet, this would be considered a successful hack
You can then keep the coins and Bitfi will make a payment to you of $250,000
Please note that we grant anyone who participates in this bounty permission to use all possible attack vectors, including our servers, nodes, and our infrastructure

Hackers began attacking the device immediately, eventually hacking it to find the passphrase used to move crypto in and out of the the wallet. In a detailed set of tweets, security researchers Andrew Tierney and Alan Woodward began finding holes by attacking the operating system itself. However, this did not match the bounty to the letter, claimed BitFi, even though they did not actually ship any bounty-ready devices.

Something that I feel should be getting more attention is the fact that there is zero evidence that a #bitfi bounty device was ever shipped to a researcher. They literally created an impossible task by refusing to send the device required to satisfy the terms of the engagement.

— Gallagher (@DanielGallagher) August 8, 2018

Then, to add insult to injury, the company earned a Pwnies award at security conference Defcon. The award was given for worst vendor response. As hackers began dismantling the device, BitFi went on the defensive, consistently claiming that their device was secure. And the hackers had a field day. One hacker, 15-year-old Saleem Rashid, was able to play Doom on the device.

Well, that’s a transaction made with a MitMed Bitfi, with the phrase and seed being sent to a remote machine.

That sounds a lot like Bounty 2 to me. pic.twitter.com/qBOVQ1z6P2

— Ask Cybergibbons! (@cybergibbons) August 13, 2018

The hacks kept coming. McAfee, for his part, kept refusing to accept the hacks as genuine.

The press claiming the BitFi wallet has been hacked. Utter nonsense. The wallet is hacked when someone gets the coins. No-one got any coins. Gaining root access in an attempt to get the coins is not a hack. It’s a failed attempt. All these alleged “hacks” did not get the coins.

— John McAfee (@officialmcafee) August 3, 2018

Unfortunately, the latest hack may have just fulfilled all of BitFi’s requirements. Rashid and Tierney have been able to pull cash out of the wallet by hacking the passphrase, a primary requirement for the bounty. “We have sent the seed and phrase from the device to another server, it just gets sent using netcat, nothing fancy.” Tierney said. “We believe all conditions have been met.”

The end state of this crypto mess? BitFi did what most hacked crypto companies do: double down on the threats. In a recently deleted Tweet they made it clear that they were not to be messed with:

I haven’t really been following this Bitfi nonsense, but I do so love when companies threaten security researchers. pic.twitter.com/McyBGqM3bt

— Matthew Green (@matthew_d_green) August 6, 2018

The researchers, however, may still have the last laugh.

Claiming your front door has an unpickable lock does not make your house secure. No more does offering a reward only for defeating that front door lock, and repeatedly saying no one has claimed the reward, prove your house is secure, especially when you’ve left the windows open.

The Sonos Beam is the soundbar evolved

Posted by | Amazon, Android, apple music, Assistant, consumer electronics, Entertainment, film, Gadgets, Google, HDMI, home audio, loudspeaker, Pandora, Reviews, Sonos, sound systems, Speaker, Spotify, Surround Sound, tablet computer, TC, technology | No Comments

Sonos has always gone its own way. The speaker manufacturer dedicated itself to network-connected speakers before there were home networks and they sold a tablet-like remote control before there were tablets. Their surround sound systems install quickly and run seamlessly. You can buy a few speakers, tap a few buttons and have 5.1 sound in less time than it takes to pull a traditional home audio system out of its shipping box.

This latest model is an addition to the Sonos line and is sold alongside the Playbase — a lumpen soundbar designed to sit directly underneath TVs not attached to the wall — and the Playbar, a traditionally styled soundbar that preceded the Beam. Both products had all of the Sonos highlights — great sound, amazing interfaces and easy setup — but the Base had too much surface area for more elegant installations and the Bar was too long while still sporting an aesthetic that harkened back to 2008 Crutchfield catalogs.

The $399 Beam is Sonos’ answer to that, and it is more than just a pretty box. The speaker includes Alexa — and promises Google Assistant support — and it improves your TV sound immensely. Designed as an add-on to your current TV, it can stand alone or connect with the Sonos subwoofer and a few satellite surround speakers for a true surround sound experience. It truly shines alone, however, thanks to its small size and more than acceptable audio range.

To use the Beam you bring up an iOS or Android app to display your Spotify, Apple Music, Amazon and Pandora accounts (this is a small sampling; Sonos supports more). You select a song or playlist and start listening. Then, when you want to watch TV, the speaker automatically flips to TV mode — including speech enhancement features that actually work — when the TV is turned on. An included tuning system turns your phone into a scanner that improves the room audio automatically.

The range is limited by the Beam’s size and shape and there is very little natural bass coming out of this thing. However, in terms of range, the Beam is just fine. It can play an action movie with a bit of thump and then go on to play some light jazz or pop. I’ve had some surprisingly revelatory sessions with the Beam when listening to classic rock and more modern fare and it’s very usable as a home audio center.

The Beam is two feet long and three inches tall. It comes in black or white and is very unobtrusive in any home theater setup. Interestingly, the product supports HDMI-ARC aka HDMI Audio Return Channel. This standard, introduced in TVs made in the past five years, allows the TV to automatically output audio and manage volume controls via a single HDMI cable. What this means, however, is you’re going to have a bad time if you don’t have HDMI-ARC.

Sonos includes an adapter that can also accept optical audio output, but setup requires you to turn off your TV speakers and route all the sound to the optical out. This is a bit of a mess, and if you don’t have either of those outputs — HDMI-ARC or optical — then you’re probably in need of a new TV. That said, HDMI-ARC is a bit jarring for first timers, but Sonos is sure that enough TVs support it that they can use it instead of optical-only.

The Beam doesn’t compete directly with other “smart” speakers like the HomePod. It is very specifically a consumer electronics device, even though it supports AirPlay 2 and Alexa. Sonos makes speakers, and good ones at that, and that goal has always been front and center. While other speakers may offer a more fully featured sound in a much smaller package, the Beam offers both great TV audio and great music playback for less than any other higher end soundbar. Whole room audio does get expensive — about $1,200 for a Sub and two satellites — but you can simply add on pieces as you go. One thing, however, is clear: Sonos has always been the best wireless speaker for the money and the Beam is another win for the scrappy and innovative speaker company.

Here are the five things I learned installing a smart mirror

Posted by | Android, computing, Gadgets, GitHub, play store, smartphones, tablet computer | No Comments

I recently received a review unit of the Embrace Smart Mirror. It’s essentially a 24-inch Android tablet mounted behind a roughly 40-inch mirror. It works well when third-party software is installed. Here’s what I learned.

It’s impossible to get a good photo of the smart mirror

I tried a tripod, a selfie stick and every possible angle and I couldn’t get a picture that does this mirror justice. It looks better in person than these photos show. When the light in the bathroom is on, the text on the mirror appears to float on the surface. It looks great. The time is nice and large, and the data below it is accessible when standing a few feet away.

When the room is dark, the Android device’s screen’s revealed because it can’t reach real black. The screen behind the mirror glows gray. This isn’t a big deal. The Android device turns off after a period of inactivity and is often triggered when the light to the bathroom is turned on. More times than not, people walking into the room will be greeted with a standard mirror until the light is turned on.

There are a handful of smart mirror apps, but few are worthwhile

This smart mirror didn’t ship with any software outside of Android. That’s a bummer, but not a deal-breaker. There are several smart mirror Android apps in the Play Store, though I only found one I like.

I settled on Mirror Mirror (get it) because the interface is clean, uses pleasant fonts and there’s just enough customization, though it would be nice to select different locations for the data modules. The app was last updated in July of 2017, so use at your own risk.

Another similar option is this software developed by Max Braun, a robotistic at Google’s X. His smart mirror was a hit in 2016, and he included instructions on how to build it here and uploaded the software to GitHub here.

Kids love it

I have great kids that grew up around technology. Nothing impresses these jerks, though, and that’s my fault. But they like this smart mirror. They won’t stop touching it, leaving fingerprints all over it. They quickly figured out how to exit the mirror software and download a bunch of games to the device. I’ve walked in on both kids huddled in the dark bathroom playing games and watching YouTube, instead, of you know, playing games or watching YouTube on the countless other devices in the house.

That’s the point of the device, though. The company that makes this model advertises it as a way to get YouTube in the bathrooms so a person can apply their makeup while watching beauty YouTubers. It works for that, too. There is just a tiny bit of latency when pressing on the screen through the mirror. This device isn’t as quick to use as a new Android tablet, but because it’s sealed in a way to keep out moisture, it’s safe to go in a steamy bathroom.

Adults will find it frivolous

I have a lot of gadgets in my house, and my friends are used to it. Their reaction to this smart mirror has been much different from any other device, though.

“What the hell is this, Matt,” they’ll say from behind the closed bathroom door. I’ll yell back, “It’s a smart mirror.” They flush the toilet, walk out and give me the biggest eye roll.

I’ve yet to have an adult say anything nice about this mirror.

It is frivolous

A smart mirror is a silly gadget. To some degree, it’s a crowd-pleaser, but in the end, it’s just another gadget to tell you the weather. It collects fingerprints like mad, and the Android screen isn’t bright enough to use it as a regular video viewer or incognito TV.

As for this particular smart mirror, the Embrace Smart Mirror, the hardware is solid but doesn’t include any smart mirror software. The Mirror is rather thin and easily hangs on a wall thanks to a VESA port. There are physical controls hidden along the bottom of the unit, including a switch to manually turn off the camera. It’s certified IP65, so it can handle a bathroom. A motion detector does a good job turning the device on. If you don’t have kids, it should stay smudge-free.

The Embrace Smart Mirror does not ship with any smart mirror software. The instructions and videos tell users to add widgets to the Android home screen. This doesn’t work for me, and I expect a product such as this to include at least necessary software. Right now, after this product is taken out of the box, it’s just an Android tablet behind a mirror, and that’s lame. Thankfully there are a couple of free apps on the Play Store to remedy this problem.

At $1,299, the Embrace Smart Mirror is a hard sell, but is among the cheapest available smart mirrors on the market. Of course, you can always build one yourself — as The Verge points out, it’s rather easy.
