How to create your own custom Android air gesture

Computerworld.com [Hacking News] - 15 Duben, 2026 - 11:45

Psst: Come close. I’ve got something to share with you, and I don’t want everyone around here to hear it.

Oh — hi! Sorry, I didn’t realize you were here. I was actually talking out loud to my phone just now, as one does, thanks to a nifty new air gesture I set up that activates my device’s voice search anytime I bring the thing close to my face.

Kinda wild, right? It is — and it’s also a massive efficiency-enhancer for those of us enlightened enough to be using Android. (Sorry, iPhone pals. But hey, Apple might give you a watered down version of something similar in another seven to 17 years, and it’s sure to be ~completely magical~. Hang tight!)

Usually, when we think about Android gestures, we think about the standard on-screen swipes and taps that help us navigate our devices — or maybe even the advanced maneuvers that make it even faster to fly around a phone like a total nerd wizard. Today, though, we’re gonna broaden our view of “gesture” to include a simple kind of physical movement that doesn’t even involve any direct device contact.

It’s a brilliantly easy way to interact with your Googley gizmo and open up new productivity-boosting possibilities — and, oh yes: It’s yet another fantastic feat you’d only be able to accomplish here in the land of Android.

[Oh, hey — love shortcuts? My free Android Shortcut Supercourse will teach you tons of advanced time-savers. Start here!]

Your Android air gesture advantage

All right — first things first: The wand we need for this fancy feat of ours is a splendidly useful Android power-user tool called MacroDroid.

MacroDroid is an advanced automation app that’s been appreciated by advanced Android phone owners for many a moon now. It can help you set up all sorts of experience-enhancing awesomeness, and the purpose we’re using for it today represents just a tiny fraction of its potential.

But it’s a good one. So to start, go grab the app, if you don’t already have it installed. It’s free with an optional premium upgrade that eliminates ads throughout its setup interface and enables some extra capabilities (which aren’t required for anything we’re about to go over). It doesn’t sell or share any sort of user data or require any disconcerting permissions.

Got it? Good. Now:

  • Open up MacroDroid and make your way through its initial welcome screens.
  • Once you see the app’s main menu screen, with a bunch of colorful boxes, flip the toggle in the upper-right corner into the on and active position to activate MacroDroid and get it up and running.
  • Then, tap the first box in the list — the one that says “Add Macro.”
width="1024" height="1018" sizes="auto, (max-width: 1024px) 100vw, 1024px">That first box is the only one you need to mess with on the main MacroDroid menu screen.

  • Now, in the red box labeled “Triggers,” tap the little plus symbol and then select “Sensors” followed by “Proximity Sensor.”
  • Make sure “Near” is selected in the pop-up that appears and tap “OK.”
  • Then, in the blue box labeled “Actions,” tap the little plus symbol and then select “Device Actions” followed by “Voice Search.”

At this point, your screen should look a little somethin’ like this:

Your Android air gesture recipe — almost ready to serve you.

JR Raphael, Foundry

And, guess what? Our work here is almost done! Give yourself a preemptive pat on the back for encouragement, and let’s wrap this bad boy up so you can start putting it to proper use:

  • All that’s left now is give this macro we created a name by tapping the “Enter macro name” line at the tippity-top of the screen and typing in any title you like — “Raise,” “Raise for input,” “Herman T. Schmidthopper,” or anything at all, really. It doesn’t make much difference, and you’re the only one who’ll ever see it.
  • Last but not least, with that out of the way, tap the left-facing arrow in the upper-left corner of the screen and confirm you want to save your creation.

You should then see it showing up and activated in the MacroDroid macro list:

Your custom Android air gesture is there and active. Excelsior!

JR Raphael, Foundry

And with that, take a deep breath: You did it! Look at you, you splendid little virtual sorcerer, you.

At this point, all that’s left is to test out your awe-inspiring new air gesture by raising your phone up close to your forehead, as if you’re about to whisper a saucy secret into its screen. (Don’t worry. I’m not listening.)

Once the phone gets close enough, the proximity sensor should detect your closeness (ooh, baby…) — and you should see a prompt for your voice search show up on the screen.

The very first time that happens, you’ll probably have to tell it that you want this action to use Google — or whatever virtual assistant you prefer, if you’ve got others installed — for your voice search.

Then, every subsequent time you bring the phone close to your suspiciously shiny mug, it’ll instantly fire up your preferred voice input companion, and you can just yap away with whatever question or command you want.

width="800" height="825" sizes="auto, (max-width: 800px) 100vw, 800px">This is me bringing my phone close to my face. Can you feel my excitement?!

JR Raphael, Foundry

The interesting twist here is that recent signs suggest Samsung is developing a similar sort of setup for its future Galaxy gizmos — but there, it looks like the air gesture will be limited to letting you raise your phone to talk to Bixby, which obviously isn’t something anyone actually wants.

The beauty of this approach is that (a) you can use it this instant, on any Android device, no matter who made it — and (b) you’ve got complete control over how it works. You could play around with having a totally different kind of action launch when you move your phone close to your face, or you could even shake up the gesture itself to involve something else entirely (like, for instance, shaking) instead of the proximity move.

Here on Android, the power is squarely in your hands. And now, you know exactly how to embrace it.

Air five!

Can Microsoft really meet its carbon-negative goal by 2030?

Computerworld.com [Hacking News] - 15 Duben, 2026 - 09:02

Six years ago, Microsoft pledged it would be carbon negative by 2030. It’s a worthy goal, and for several years the company was on track to meeting it.

Then generative AI came along and the world changed. Electric power demand from data centers will more than double between 2025 and 2030, according to the International Energy Agency (IEA). “The US economy is set to consume more electricity in 2030 for processing data than for manufacturing all energy-intensive goods combined, including aluminum, steel, cement and chemicals,” the agency projects.

All this new electricity generation means much more carbon will be put into the atmosphere, exacerbating climate change. 

What does this mean for Microsoft’s pledge to be carbon negative within four years now? Just two months ago, the company claimed it was on track and had recently passed a major milestone in getting there by becoming carbon neutral. Detractors say nothing could be further from the truth — that it’s just smoke and mirrors, and the company has become a serious polluter and engine for accelerated climate change.

Who’s right? To find out, we’ll look at Microsoft’s claims, lay out what its opponents say, and finally, compare the company’s promises to what it’s actually done.

Microsoft’s rosy view

Microsoft claims not just that it’s on track to becoming a carbon-neutral company by 2030, but that 2025 marked an important turning point on the journey. The headline of the company’s blog post about it in February says it all: “A milestone achievement in our journey to carbon negative.”

From just that headline, you’d think the company was boasting it had reduced its carbon emissions drastically. That’s not the case. Microsoft wrote the post in such an oblique way that it’s tough to know just what it’s claiming. Specifically, the company claimed to have met “our aim to match 100% of our annual global electricity consumption with renewable energy.”

That’s a roundabout way of describing carbon offsets — paying other companies to generate renewable energy that don’t release carbon. In that way, Microsoft can say it’s offsetting its own carbon emissions. Eventually, it claims, by using offsets it will accomplish its goal of removing more carbon from the atmosphere than it’s putting into it by 2030.

Is Microsoft greenwashing?

Critics say Microsoft’s carbon emissions are skyrocketing, and carbon offsets are little more than greenwashing. The Stand.earth Research Group, which does investigative research about climate change, warns that a single new recently announced Microsoft AI data center in West Virginia will “unleash a 44% increase in the company’s annual emissions.” 

The group also says that when the facility reaches its full generating capacity in 2031, “Microsoft and co-located partners will emit 25.55 million metric tons of CO₂ per year, as much as putting nearly 6 million cars on the road.”

Keep in mind, that’s just a single facility. 

A year ago, Sustainability Magazine warned that even though Microsoft had made substantial investments in renewable energy and conservation, the company’s total carbon emissions had increased by more than 24%. Things have only gotten worse since then.

Many environmentalists don’t believe carbon offsets make up for the carbon emissions a company creates — they call all offsets greenwashing. David Keith, who is head of the Climate Systems Engineering initiative at the University of Chicago and lead author of a report by the UN’s Intergovernmental Panel on Climate Change (IPCC), put it bluntly: “I think all this voluntary stuff and companies claiming to be green is basically greenwashing crap.” 

The upshot

So who’s right? If Microsoft buys enough offsets by 2030, will the company really be carbon negative?

There’s an easy way to find out — look at what Microsoft President and Vice Chair Brad Smith promised in his 2020 blog post, “Microsoft will be carbon negative by 2030.” In the post, he noted that merely buying offsets isn’t enough; Microsoft needs to completely switch to renewable power for the vast majority of its direct energy use, buying offsets only to make up for its much smaller indirect energy use, such as employee travel or the electricity its customers use when using Microsoft products.

Here’s what he promised: “By 2025, we will shift to 100% supply of renewable energy, meaning that we will have power purchase agreements for green energy contracted for 100% of carbon emitting electricity consumed by all our data centers, buildings, and campuses.”

That hasn’t happened. 

The company’s carbon emissions from its oil- and gas-powered data centers skyrocketed in the last few years, and they’re getting worse. By the company’s own definition, it is not now carbon neutral, won’t be carbon negative by 2030, and isn’t likely to get there — ever.
