Pokémon GO’s ARKit-Powered Release Coming Soon

The most well-known augmented reality smartphone game will soon be better than ever. As was previously announced at WWDC, Pokémon GO is adopting Apple’s ARKit framework to provide a more true-to-life AR experience. The Pokémon GO website announced that this update, featuring what the post dubs ‘AR+’, is launching very soon.

AR+ will not only make Pokémon appear more accurately in space, but it also brings enhancements to actual gameplay. Because the game will be able to better measure distance and placement of objects, each Pokémon found in the wild will now have an awareness meter. The meter fills up as Pokémon grow more aware of your looming presence, and if the meter fills up completely, the Pokémon will run away. But if you sneak up carefully, not only will you prevent the Pokémon from fleeing, but you’ll earn some nice perks: an Expert Handler bonus that increases the amount of XP and Stardust you receive, and a better chance at earning Great and Excellent Throw bonuses. These additions are a clever way of using ARKit to not only improve the realism of the game’s visuals, but its mechanics too.

One either nice perk of AR+ is that, as a side benefit of being fixed to a precise point in space, Pokémon will display in an accurate scale, so you can walk up and see just how big or small a Pokémon truly is.

While Pokémon GO’s days as a worldwide phenomenon are over (at least for now), the game continues to receive important updates, and the adoption of ARKit appears to be a key one. The update’s exact release timeline is unclear, but by all indications it’s imminent.

Apple Shares Differential Privacy Insights for Emoji and QuickType Keyboard→

In the most recent issue of Apple’s Machine Learning Journal, titled “Learning with Privacy at Scale,” the team working on differential privacy shares details on exactly how its systems work. While much of the article is highly technical in nature, it concludes by sharing results from several real-life applications. Regarding emoji:

The data shows many differences across keyboard locales. In Figure 6, we observe snapshots from two locales: English and French. Using this data, we can improve our predictive emoji QuickType across locales.

The referenced chart is featured above, showing the popularity of certain emoji in different parts of the world.

The results regarding QuickType words aren’t presented in a chart, but the article does mention words in several specific categories that Apple has been able to learn about thanks to differential privacy.

The learned words for the English keyboard, for example, can be divided into multiple categories: abbreviations like wyd, wbu, idc; popular expressions like bruh, hun, bae, and tryna, seasonal or trending words like Mayweather, McGregor, Despacito, Moana, and Leia; and foreign words like dia, queso, aqui, and jai. Using the data, we are constantly updating our on-device lexicons to improve the keyboard experience.

Another category of words discovered are known words without the trailing e (lov or th) or w (kno). If users accidentally press the left-most prediction cell above the keyboard, which contains the literal string typed thus far, a space will be added to their current word instead of the character they intended to type. This is a key insight that we were able to learn due to our local differentially private algorithm.

Though the article doesn’t mention it, presumably the latter example of accidentally-tapped QuickType suggestions might lead to Apple adjusting sensitivity for its touch targets related to the ‘e’ button and the left-most prediction cell. It’s interesting to consider what other unexpected lessons may be learned from differential privacy data.

Apple Releases iOS 11.2 with Apple Pay for iMessage, Fix for Notification Bug, and More

Today in an unusual weekend launch, Apple released iOS 11.2 to the public. The hallmark feature for US users is Apple Pay for iMessage, but that service reportedly won’t go live until at least Monday. The reason the update launched today is that current versions of iOS contains a bug that may crash springboard on December 2nd – as users all over the world are now discovering – and 11.2 contains the fix for that bug.

Apple has published a support article where they urge users encountering the issue to follow steps to disable notifications in order to stop the crashes, then update to iOS 11.2 before turning notifications back on.

Besides the bug fix, iOS 11.2 includes the aforementioned Apple Pay for iMessage for US users, new wallpaper options for iPhone X users, and a handful of other minor improvements.

CARROT Weather Adds Powerful, Redesigned Apple Watch App

Version 4.3 of CARROT Weather for iOS launched today, bringing a ground-up redesign of its Apple Watch app that offers power and flexibility in a beautifully designed package.

CARROT Weather’s story isn’t that it had an old, out-dated Apple Watch app that’s now finally become modern. Instead, today’s update takes what was already a very good Watch app and replaces it with a great one.

Before this big redesign, CARROT’s Watch app was already fast and flexible, with an assortment of customization options for things like complications. It even worked well when your Watch was running solo; by contrast, most third-party Watch apps depend entirely on a paired iPhone and can’t function at all when untethered from the device. CARROT’s new Watch app keeps all these positives, improves upon them, and adds a lot more to the package.

MindNode 5: Digital Mind Mapping Finally Clicked for Me

I have a confession: I’m not a big mind map guy. I know Federico uses a mind map for his iOS review each year, and lots of other people love visualizing their thoughts that way too, but mind maps have never really clicked for me – at least not on computers.

Up until recently, whenever I needed to do a brain dump and get my thoughts better organized, I would often turn to pen, paper, and a hand-drawn mind map. It’s an odd habit, since I shun paper for digital tools in every other case I can think of. Yet this one holdout remained.

My main problem with digital mind maps is that they have always felt unnatural. When using a traditional computer, moving and clicking via trackpad was cumbersome for me; with a format as creatively freeing as a mind map, it seems especially important to have freeform input methods. Even on devices like the iPad though, while touch input certainly helped remove a barrier, there was still always something missing in my view. Digital mind mapping still wasn’t quite right.

MindNode 5 on iOS fixes that.

MindNode has long been one of the premier mind mapping apps for Mac and iOS, and its version 5 is a huge update that, for me at least, centers around two main changes: a streamlined, intuitive user interface, and the adoption of drag and drop support. There’s a lot more to this update than those two things, with plenty of goodies that die-hard MindNode fans will appreciate, but for users like me – those dissatisfied with digital mind mapping, or even inexperienced at it altogether – the most important changes are those that make the app more approachable, and the new UI and drag and drop certainly do that.

Focos: Powerful Depth Image Controls in a Fun Package

The iPhone’s camera has long been one of its most important features. Every year when new models are introduced, it’s a sure bet that camera improvements are part of the package. Last year that remained true, but it also proved an even more special year for the iPhone’s camera setup. The introduction of dual rear-facing cameras with Portrait mode was something different – pictures no longer just looked a little better than on older iPhone models, they looked almost professional-quality.

This year, whether you picked up a new iPhone or not, Portrait mode is a better feature than before. Part of this is due to software improvements in iOS 11, but another key benefit is that third-party developers now have access to the depth information in Portrait photos. For the first time, Portrait images taken with the iPhone can be edited and enhanced in unique ways, and Focos is a new app that takes full advantage of that opportunity.

Can Clips Be a Modern Day Photo Booth?→

Karan Varindani considers the potential of Apple’s Clips to be a spiritual successor to Photo Booth:

With the iPad 2, back in early 2011, Apple brought Photo Booth to the iPad. I distinctly remember thinking that this was a no-brainer at the time. Growing up in Ghana, there weren’t that many Macs in my high school, but everybody that had one used Photo Booth. It was very regular to walk into the sixth form (senior year) common room and see groups of friends, myself included, behind a MacBook playing with the filters. Talking to several of my American friends, it sounds like it was the same deal here. I always thought that it was only a matter of time before Apple brought Photo Booth to the iPhone, but six years later it still just ships with Macs and iPads (and I don’t think that it’s been updated in that time).

Playing with the Selfie Scenes in Clips last week, I had the same feeling that I did playing with Photo Booth on my Mac many years ago. It was a little surreal, as someone with incredible front-camera shyness, to find myself having so much fun with it. The whole experience had me thinking: In a few years, once the Face ID technology has spread to the rest of the iOS line (and maybe even the Mac), could Clips be the successor to Photo Booth? Between Selfie Scenes, stickers, Live Titles, and fast sharing to social media, it seems the perfect fit.

I think the best modern equivalent of that Photo Booth social experience is Snapchat’s lenses, which I’ve observed can consistently deliver laughter and interest among a group of friends or family members. While Clips’ Selfie Scenes offer a similarly neat technical effect, if Apple is serious about being successful with the app, a couple big changes need to take place: the square orientation limit has to go, and Clips needs better hooks into apps like Instagram and Snapchat than the share sheet provides.

Photo Booth’s prime was a very different era than where we are today, and without the aid of a true social network it will be hard for Apple to replicate its success. So far, Animoji seem much closer to meeting that goal than Clips.

Playground AR: A Physics Sandbox for Freeform Play

One of childhood’s simple joys for many of us was getting our creative juices flowing by playing with building blocks. It’s one of those tactile, imaginative outlets that adulthood features far less of. Blocks also brought the added benefit of getting to destroy the work you’d built – a task similarly delightful to the actual building.

Recently my wife and I were babysitting twin 1-year-old boys, owners of a big bucket full of colorful, cardboard bricks. All throughout the night I enjoyed building small towers with the bricks, and the boys would have a blast knocking those towers down. Even when they were on the other side of the room distracted by something else, if they saw me stack three or more bricks together, they’d quickly come running to play demolition crew.

Playground AR is a new app from developer Marc Sureda that uses ARKit to bring the joys of childhood play to all ages – and with no mess to clean up either. The app provides a variety of toys that let you both build and destroy, with a physics system backing it all up to make the experience a delight.

There are three main modes in Playground AR: one is for placing objects in your playground, another lets you better survey and capture photos of what you’ve built, and the last is for picking up and moving existing objects. Objects you can place of course include blocks of varying shapes and sizes, but there are also lots of other fun, interesting toys to experiment with – trucks, helicopters, dice, spinning widgets, and more.

The physics engine is what makes Playground truly shine. Stacking blocks too high, for example, will cause your creation to topple over if the stack isn’t well-balanced. Dominos can be strung together in an elaborate setup then knocked down by a rolling ball. Magnetized blocks will stick together even if gravity or another object forces them to fall. Balloons can be attached to objects, and depending on an object’s weight and the number of balloons, the object will eventually be sent flying into the stratosphere. But I would be remiss if I didn’t mention my favorite physics demonstration: placing bombs and TNT containers in your playground to blow everything up. It’s brilliant.

If you want to spend some time goofing around in an AR sandbox, building and destroying in all kinds of creative ways, you can pickup Playground AR on the App Store for $1.99.
