I Tried an AR Laptop. It’s Way Ahead of Its Time

The Spacetop is like a Chromebook for AR headsets. With Apple’s hardware looming, it also feels like a reminder of how computers could change.

A small keyboard and trackpad lies in my lap. But there’s no screen. Not that you can see, anyway. To me, I have a curved wraparound workspace with dozens of windows open. I’m seeing it on a pair of AR glasses (with prescription inserts) perched on my nose.

I first tried the Spacetop in Las Vegas back in January, but the company that developed it, Sightful, is finally announcing the early-access product experiment now. I’ve seen tons of AR and VR headsets, but very few unique peripherals designed to work together with these future goggles and glasses. Instead of gaming or social experiences, Spacetop’s main pitch is to turn laptops into AR-assisted devices with endless virtual displays.

If that sounds like a weird pitch, consider that I’ve already lived it. I’ve paired Meta’s Quest Pro to my laptop to extend its virtual monitors around my head, and plenty of solutions like this already exist using available apps. The interfaces can be clunky, and the hardware isn’t totally made to be mobile. Spacetop’s keyboard base, with its own Qualcomm processor inside, acts as a spatially tracked anchor that the AR glasses can follow and track the floating displays to. The tracking can work while in motion in a car or plane, and a button on the keyboard can make the floating displays vanish for an in-room conversation with someone, toggling the virtual screens on and off.

This visualization of working on Spacetop is actually very similar to the experience of using it, except the field of view at any time is smaller (imagine viewing through a narrower window).

The Spacetop comes with a pair of NReal Light AR glasses as part of its package, which need to be physically tethered to the keyboard to work. Sightful’s founders are planning for wireless options eventually, but found the tethered option more reliable for consistent tracking right now. Also, the whole concept could eventually work with other AR and mixed-reality headset hardware down the road.

That would make sense, considering how many devices should be on their way: Apple’s, to start, and whatever Samsung, Google and Qualcomm are cooking up in the next year or so. NReal’s glasses are fine, but don’t work over my own glasses. Instead, I had to use prescription inserts, which Sightful will make for buyers of the hardware. The inserts I tried weren’t a perfect match, but were enough to appreciate that the display resolution was more than good enough for monitor readouts. The field of view, however, is narrower than most VR headsets: it can show something like a 40-inch TV screen as seen across a table, but I have to turn my head to see the other floating windows of other minimized browsers in the Spacetop’s Chrome-like software interface.

Zooming into displays, or scrolling around, is all done through trackpad and keyboard work. The keyboard itself is the interface.

Sightful’s team has experience in AR: Founders Tamir Berliner and Tomer Kahan came from Magic Leap, and Berliner also founded Primesense, the depth-sensing technology that powered Microsoft Kinect and which Apple acquired as the foundation to its Face ID TrueDepth camera.

As Apple’s headset begins to imagine how mixed reality could work with other devices — perhaps iPads, or the Apple Watch — upcoming glasses and goggles will start to imagine working better with phones or laptops, and other tools to come. It makes sense that new peripherals would arrive as well — not just controllers, but tracking rings, wearable trackers and a new wave of keyboards designed specifically for mixed reality.

I think Spacetop is a bit ahead of the curve here, and while it’s designed as a primary computer with its own headset, the future may belong to smart accessories that evolve from this idea to work with more headsets to come. If VR and AR are ever going to be more than just places for games, better work tools need to arrive. Spacetop is a pretty fascinating first step to what I imagine will be a lot more on this front.

Get Ready for a Striking Aurora That Could Also Disrupt Radio Communications

Don’t expect the storm to cause a lingering problem, though.

A geomagnetic storm is threatening radio communications Monday night, but that doesn’t mean you should be concerned. In fact, it may be an opportunity to see a colorful aurora in the night sky.

The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch after witnessing a coronal mass ejection from the sun on Saturday. The watch, which was issued over the weekend and will expire after Monday, said the onset of the storm passing over Earth on Sunday night represented a «moderate» threat to communications. As the storm continues to pass through, it could deliver a «strong» threat on Monday night that could cause radio communications to be temporarily disrupted during the worst of it.

Even so, NOAA said, «the general public should not be concerned.»

A coronal mass ejection occurs when magnetic field and plasma mass are violently expelled from the sun’s corona, or the outermost portion of the sun’s atmosphere. In the vast majority of cases, the ejection occurs with no real threat to Earth. However, in the event the ejection happens in the planet’s direction, a geomagnetic storm occurs, and the Earth’s magnetic field is temporarily affected.

In most cases, geomagnetic storms cause little to no disruption on Earth, with radio communications and satellites affected most often. In extreme cases, a geomagnetic storm can cause significant and potentially life-threatening power outages — a prospect that, luckily, the planet hasn’t faced.

Switching poles

Every 11 years, the sun’s magnetic poles switch, with the north pole and south pole swapping positions. During those cycles, the sun’s activity ramps up as it gets closer to pole-switching time. The height of its activity is called solar maximum, and scientists believe we either may be entering the solar maximum or may be already in it.

During periods of heightened solar activity, sunspots increase on the sun and there’s an increase in coronal mass ejections, among other phenomena. According to NOAA, solar maximum could extend into October of this year before the sun’s activity calms and it works towards its less-active phase, solar minimum.

Even when geomagnetic storms hit Earth and disrupt communications, the effects are usually short-lived. Those most affected, including power grid operators and pilots and air traffic controllers communicating over long distances, have fail-safe technologies and backup communications to ensure operational continuity.

But geomagnetic storms aren’t only about radios. In most cases, they also present unique opportunities to see auroras in the night sky. When the storms hit, the plasma they carry creates a jaw-dropping aurora, illuminating the night sky with brilliant colors. Those auroras can be especially pronounced during the most intense phases of the storm, making for nice stargazing.

If you’re interested in seeing the aurora, you’ll need to be ready. The NOAA said the «brunt of the storm has passed» and even if it lingers into Tuesday, there won’t be much to see after Monday night.

Last Total Solar Eclipse for 20 Years Is Coming: How to See and Photograph It

It’s your last chance until 2044.

Get your eclipse glasses ready, Skygazers: the Great American Eclipse is on its way. On April 8, there’ll be a total eclipse over North America, the last one until 2044.

A total solar eclipse happens when the moon passes between the Earth and the sun, blocking the sun and turning an otherwise sunny day to darkness for a short period of time. Depending on the angle at which you’re viewing the eclipse, you may see the sun completely shrouded by the moon (called totality) or some variation of it. The more off-angle you are and the further you are from the path of the eclipse, the less likely you’ll be to see the totality.

The 2024 total solar eclipse will happen on Monday, April 8. The Great American Eclipse will reach the Mexican Pacific coast at 11:07 a.m. PT (2:07 p.m. ET), and then traverse the US in a northeasterly direction from Texas to Maine, and on into easternmost Canada. If you want a good look at it, but don’t live in the path of totality, you shouldn’t wait much longer to book accommodation and travel to a spot on the path.

Or how about booking a seat in the sky? Delta Airlines made headlines for offering a flight that allows you to see the entire path of totality. Its first eclipse flight, from Austin, Texas, to Detroit sold out quickly. But as of Monday, Delta has added a second flight from Dallas to Detroit, which also covers the path of totality. The airline also has five flights that will offer prime eclipse viewing.

Not everyone can get on one of those elusive eclipse-viewing flights. Here’s a look at other options to nab a chance to see this rare sight and what to know about it.

Total solar eclipse path

The eclipse will cross over the Pacific coast of Mexico and head northeast over mainland Mexico. The eclipse will then make its way over San Antonio at approximately 2:30 p.m. ET on April 8 and move through Texas, over the southeastern part of Oklahoma and northern Arkansas by 2:50 p.m. ET.

By 3 p.m. ET, the eclipse will be over southern Illinois, and just 5 minutes later, will be traveling over Indianapolis. Folks in northwestern Ohio will be treated to the eclipse by 3:15 p.m. ET, and it will then travel over Lake Erie and Buffalo, New York, by 3:20 p.m. ET. Over the next 10 minutes, the eclipse will be seen over northern New York state, then over Vermont. By 3:35 p.m. ET, the eclipse will work its way into Canada and off the Eastern coast of North America.

Best places to watch the Great American Eclipse

When evaluating the best places to watch this year’s total eclipse, you’ll first want to determine where you’ll have the best angle to see the totality. The farther off-angle you are — in other words, the farther north or south of the eclipse’s path — the less of an impact you can expect.

Therefore, if you want to have the best chance of experiencing the eclipse, you’ll want to be in its path. As of this writing, most of the cities in the eclipse’s path have some hotel availability, but recent reports have suggested that rooms are booking up. And as more rooms are booked, prices are going up.

So if you want to be in the eclipse’s path, and need a hotel to do it, move fast. And Delta’s eclipse-viewing flight from Dallas to Detroit has just four seats left at the time of publication.

Eclipse eye safety and photography

As with any solar eclipse, it’s critical you keep eye safety in mind.

During the eclipse, and especially during the periods before and after totality, don’t look directly at the sun without special eye protection. Also, be sure not to look at the sun through a camera (including the camera on your phone), binoculars, a telescope or any other viewing device. This could cause serious eye injury. Sunglasses aren’t enough to protect your eyes from damage.

If you want to view the eclipse, you’ll instead need solar viewing glasses that comply with the ISO 12312-2 safety standard. Anything that doesn’t meet that standard or greater won’t be dark enough to protect your eyes. Want to get them for free? If you’ve got a Warby Parker eyeglasses store nearby, the company is giving away free, ISO-certified solar eclipse glasses at all of its stores from April 1 until the eclipse, while supplies last.

If you don’t have eclipse viewing glasses handy, you can instead use indirect methods for viewing the eclipse, like a pinhole projector.

In the event you want to take pictures of the eclipse, attach a certified solar filter to your camera. Doing so will protect your eyes and allow you to take photos while you view the eclipse through your lens.

There’s also a new app to help you both protect your eyes and take better photos of the eclipse on your phone. Solar Snap, designed by a former Hubble Space Telescope astronomer, comes with a Solar Snap camera filter that attaches to the back of an iPhone or Android phone, along with solar eclipse glasses for protecting your eyesight during the event. After you attach the filter to your phone, you can use the free Solar Snap Eclipse app to zoom in on the eclipse, adjust exposure and other camera settings, and ultimately take better shots of the eclipse.

2024 eclipse compared to 2017

The last total solar eclipse occurred in 2017, and many Americans had a great view. Although there are plenty of similarities between the 2017 total solar eclipse and the one coming April 8, there are a handful of differences. Mainly, the 2024 eclipse is going to cover more land and last longer.

The 2017 eclipse started over the northwest US and moved southeast. Additionally, that eclipse’s path was up to 71 miles wide, compared with a maximum width of 122 miles for this year’s eclipse. Perhaps most importantly, the moon completely covered the sun for just 2 minutes, 40 seconds in 2017. This year, maximum totality will last for nearly four-and-a-half minutes.
