Going in-depth with Nintendo's augmented reality Mario Kart RC car - Ars Technica

rest.indah.link

The toy industry has given us plenty of radio-controlled cars that are modeled after the Mario Kart franchise. But the $100 Mario Kart Life: Home Circuit, announced last month, promises to be the first to integrate such a toy car with an augmented reality camera and attendant Switch game experience.

While we haven't gotten any hands-on time with Mario Kart Live: Home Circuit yet, we were able to participate in a recent livestream demo of the RC car/AR app combo ahead of its planned October 16 release. What we saw doesn't quite match up to a full-fledged Mario Kart game, but it looks like it could add a lot of creativity and imaginative play opportunities to the standard RC car experience.

On your mark...

The demo walked us through the Mario Kart Live setup process, which starts off by using the camera on the Kart to scan a QR code found on the free downloadable Switch app (that app won't work at all without the Kart). With that scan, the Kart and Switch are connected directly via Wi-Fi, without the need for any router or live Internet connection.

When you put the Kart down, you get an over-the-shoulder view of what the camera sees on your Switch screen (either docked or in handheld mode, standard or Switch Lite). Nintendo isn't discussing specifics of the streaming resolution/frame rate of this setup, but a Nintendo representative said he hadn't seen any latency between the Switch controls and the physical movements of the Kart itself.

The camera's positioning means you don't see the actual physical Kart from this view. Instead, you see your Kart represented as an animated 3D model at the bottom of the livestreamed camera view. This can lead to some lively interactions, like when Mario playfully gets your attention by knocking on the "camera's" glass.

Get set...

With the connection established, you set up your course by simply driving around your room; wherever your Kart goes, the virtual track will follow at a uniform width. The only physical requirement is four fold-out cardboard AR gates, each about three times the width of the Kart itself. You have to use all four of these in designing your course (no more, no less), and the Kart has to roll under each one in order, though you can loop back through a gate multiple times before moving to the next one.

You can make your course as simple or as complicated as you want between gates, adding zigzags, loops, intersections, or long straightaways to your heart's content. But the gates are the only strict requirement when navigating the course later; the game itself offers no penalty for driving off the course you lay out at any point.

You're driving a physical Kart, though, so you can set up walls and barriers on the side of your virtual course to help encourage or force players to drive the "right" way. There's also a "smart steering" option for racers that helps automatically keeps the Kart on track.

"You're playing a game, and it's up to you to make your own rules," a Nintendo representative told Ars Technica. "In multiplayer, though, you're definitely going to get called out [for cutting corners]."

...Go!

With your course built, you can race through a simple Grand Prix mode that takes you through the basic track three times, each with different environmental hazards and visual themes (snow, rain, underwater, lava, 8-bit, Rainbow Road, etc.). While you set up the layout of the road itself, in this mode the game automatically puts out customizations including boosts, item boxes, and coins (used to unlock cosmetic options, not to increase your top speed). The modification are intended to make each race in the three-race series a bit harder, with the usual Mario Kart point-scoring for your speed and placement.

In Explore mode, you can add a bit more virtual customization to the gates themselves, choosing from a variety of hazards or boons when you drive under them. The most interesting of these was a Magikoopa effect, which mirrors your camera view of the course (and thus the real world around it) until you hit it again. There's also a Time Trial mode that lets you race against a ghost version of your best time and tracks the exact positioning of your Kart in that race.

In single-player races, computer-controlled Koopalings (and Bowser Jr.) serve as computer-controlled opponents. This being Mario Kart, those virtual opponents can affect your Kart with a variety of items. This means real-world effects on your physical Kart, too; a Red Shell or Piranha Plant gate will stop your Kart temporarily, while a Sandstorm or Magnet Gate actually make your Kart drift left or right briefly. And yes, you can give your Kart a physical speed boost with a mushroom (or by holding a drift for the requisite time).

While the course-customization options don't seem deep enough to really emulate a full-fledged Mario Kart game, Mario Kart Live still looks like a fun way to bring the basic concepts of the series into the real world. We're looking forward to getting some hands-on time with it soon.

Microsoft launches Surface Laptop Go with $899 competitor to MacBook Air - AppleInsider

rest.indah.link

Microsoft on Thursday introduced the Surface Laptop Go, a lighter-weight and less powerful iteration of the company's notebook lineup at a price that undercuts Apple's cheapest MacBook Air.

The Surface Laptop Go is much more affordable than other Surface devices, and the lower-end models seem aimed at poaching Chromebook buyers. But the more expensive tiers could be a competitor to Apple's MacBook Air.

Instead of any significant new features, most of the changes on the here are on form factor and price. It packs a 12.4-inch display, weighs less than a MacBook Air at 2.45 pounds, and starts at $549.

Here's how it stacks up against Apple's MacBook Air.

High-end Surface Laptop Go versus MacBook Air

Although it starts at $549, those are underpowered compared to the MacBook Air. The $899 top tier model of the Surface Laptop Go could give the MacBook Air some competition. It sports 8GB of RAM, 256GB of SSD storage, and a quad-core 10th-generation Intel Core i5 processor. The MacBook Air costs $100 more, but packs a dual-core 10th-generation Intel Core i3 processor.

Despite the 12.4-inch display, the Surface Laptop Go features a 1536 x 1024 resolution, with a 3:2 aspect ratio. Apple's MacBook Air sports a 13.3-inch display at a 2560 x 1600 resolution and a 16:10 aspect ratio, that utilizes Apple's True Tone technology.

The Surface Laptop Go features a single USB 3.2 type-C port and a single USB 3.1 type-A port, as well as a 3.5mm headphone jack and a Surface Connect charging port. The camera is a 720p webcam that won't support Windows Hello facial recognition. For biometrics, users get a fingerprint reader in the power button — but only on the $699 and $899 models. The MacBook Air features two Thunderbolt 3 ports and an integrated Touch ID sensor.

The Surface Laptop Go also features Wi-Fi 6, which the MacBook Air lacks, and a fast charging mechanism that can top a battery off to 80% in an hour. On the other hand, all of Apple's laptops are made of aluminum. The Surface Laptop Go, as a cost-saving mechanism, features a plastic housing.

Base models

The $899 Surface Laptop Go is the top-end model and the most serious competition to Apple's MacBook Air. But Microsoft also has two other tiers for the laptop, and both leave quite a bit to be desired.

For example, the base model isn't much of a laptop replacement, packing just 4GB of RAM and 64GB of eMMC storage. Compared to competing PC makers, consumers can get more bang for their buck for $549. Of course, buyers are paying for the Surface design, as well as features like a full keyboard and Microsoft's Windows Precision trackpad.

There's also a mid-tier $699 model that comes with a more-capable 8GB of RAM, but is still stuck with a 128GB SSD drive. Apple's cheapest MacBook Air model at least has 256GB as the standard storage configuration.

Available in Blue, Sandstone, and Platinum, the Surface Laptop Go is available for preorder starting Thursday. It'll start shipping on Oct. 13.
