No more headaches: 7 ways to magnify your iPhone, iPad or Mac screen

This zoom magnification tool on iPhone and iPad means the end of squinting to read the small print on your device.

With the past year’s spike in remote work due to the COVID-19 pandemic, we’re spending a lot of time looking at screens. And while we’re navigating screens’ headache-inducing blue light and tiny print on websites, we should remember that technology must also be accessible for blind and visually impaired users.

Fortunately, Apple added a number of accessibility features in its iOS 15 release that you can explore and customize under Settings > Accessibility. Zoom is a new reworked accessibility feature under iOS 15. (And no, we don’t mean more virtual meetings.) Here’s what you need to know about Apple’s Zoom feature:

Apple’s Zoom tool: What it is and where to find it

The Zoom feature lets you magnify specific parts of your screen. You can customize the feature to magnify the whole screen or a draggable windowed view. Zoom also allows you to turn on gestures like double-tapping three fingers to activate Zoom, move around your screen, and change the magnification.

To find Zoom, open the Settings app on your iPhone, iPad or Mac, tap Accessibility and choose Zoom.

How the Zoom tool works

Here’s what you’ll turn on or off to make the magnification feature work best for you.

Follow Focus lets you track your selections, like your text insertion point, as well as your typing.
Smart Typing becomes available if you turn on Follow Focus. This lets you switch to Window Zoom when the keyboard pops up. Window Zoom magnifies a section of screen in a window that you can drag around to expand what you need to see, like a digital magnifying glass. Also, once the keyboard pops up, you can double tap to magnify where you’re typing, but the keyboard stays put.
Keyboard shortcuts only apply if you’ve connected an external keyboard to your iPad. If you have, simply toggle the option on to find and customize keyboard shortcuts like toggling Zoom, moving your Window, resizing your Window and more. If you open Zoom on your Mac, you can turn on Zoom keyboard shortcuts, scroll gestures, enable hover text and zoom on the touchbar. For example, toggle zoom is Option + Command + 8. Pressing that combination lets you zoom in and back out. You can also choose whether you want to magnify full screen, split screen, or picture-in-picture mode.

Zoom controller gives you quick access to controls like what activates for single, double and triple taps on the screen. You can also choose to Show Controller on the screen. This puts a little icon on the screen that I found helpful when moving the Window around the screen. Think of it as a little map to keep you oriented when you’ve magnified a section of screen. You can choose between five different colors to make the icon more visible, as well as change the opacity.
Zoom Region lets you choose between a Window Zoom, Full Screen Zoom or Pinned Zoom. Window Zoom will magnify a section of your screen, but you’ll still be able to see some of the unmagnified screen and pan over that area. Full Screen Zoom eliminates the window and works like double tapping to magnify and pan around on a photo. Pinned Zoom lets you choose a specific section of the screen — top, left, right or bottom — and keeps the unpinned section in regular size.
Zoom filter lets you customize the magnified section’s coloring — inverted, grayscale, grayscale inverted or low light.
Maximum Zoom Level is a simple slider that lets you customize the magnification anywhere between 1.2x all the way to 15x.

How Much Energy Do Your AI Prompts Consume? Google Just Shared Its Gemini Numbers

Current measurements of AI’s impact aren’t telling the full story. Google has offered a new method it hopes to standardize.

The explosion of AI tools worldwide is increasing exponentially, but the companies that make these tools often don’t express their environmental impact in detail.

Google has just released a technical paper detailing measurements for energy, emissions and water use of its Gemini AI prompts. The impact of a single prompt is, it says, minuscule. According to its methodology for measuring AI’s impact, a single prompt’s energy consumption is about the equivalent of watching TV for less than 9 seconds.

That’s quite in a single serving, except when you consider the variety of chatbots being used, with billions of prompts easily sent every day.

On the more positive side of progress, the technology behind these prompts has become more efficient. Over the past 12 months, the energy of a single Gemini text prompt has been reduced by 33x, and the total carbon footprint has been reduced by 44x, Google says. According to the tech giant, that’s not unsubstantial, and it’s a momentum that will need to be maintained going forward.

Google did not immediately respond to CNET’s request for further comment.

Google’s calculation method considers much more

The typical calculation for the energy cost of an AI prompt ends at the active machine it’s been run on, which shows a much smaller per-prompt footprint. But Google’s method for measuring the impact of a prompt purportedly spans a much wider range of factors that paint a clearer picture, including full-system dynamic power, idle machines, data center overhead, water consumption and more.

For comparison, it’s estimated that only using the active TPU and GPU consumption, a single Gemini prompt uses 0.10 watt-hours of energy, 0.12 milliliters of water and emits 0.02 grams of carbon dioxide equivalent. This is a promising number, but Google’s wider methodology tells a different story. With more considerations in place, a Gemini text prompt uses 0.24Wh of energy, 0.26mL of water and emits 0.03 gCO2e — around double across the board.

Will new efficiencies keep up with AI use?

Through a multilayered series of efficiencies, Google is continually working on ways to make AI’s impact less burdensome, from more efficient model architectures and data centers to custom hardware.

With smarter models, use cases and tools emerging daily, those efficiencies will be critical as we immerse ourselves deeper in this AI reality.

Vivo Launches Mixed-Reality Headset, an Apple Vision Pro Competitor

Vivo Vision has many of the same design elements as Apple’s VR/AR, but is only available in China, for now.

Look-alikes of Apple products often pop up in China, and mixed-reality headsets have now joined the party. Chinese smartphone maker Vivo has introduced the Vivo Vision, a headset mixing both AR and VR, and it bears many similarities to the Apple Vision Pro.

The company announced the Vivo Vision Discovery Edition at its 30th anniversary celebration in Dongguan, China, saying it’s «the first MR product developed by a smartphone manufacturer in China, positioning Vivo as the first Chinese company to operate within both the smartphone and MR product sectors.»

The Vivo Vision, currently only an in-store experience in mainland China, has a curved glass visor, an aluminum external battery pack and downward-pointing cameras like the Vision Pro. But it also has some differences — an 180-degree panoramic field of view and a much lighter weight at 398 grams (versus the Vision Pro’s 650 grams).

CNET asked Vivo if it plans to sell the Vivo Vision to non-China markets, but the company did not immediately respond.

The Vivo Vision runs on OriginOS Vision, Vivo’s mixed-reality operating system. It supports 3D video recording, spatial photos and audio, and a 120-foot cinematic screen experience.

The starting cost in China will be $1,395 (converted to US dollars), compared to the Vision Pro at $3,500.

Even if the Vivo Vision came to the consumer market in the US, it might not matter much to Apple’s bottom line. The Vision Pro hasn’t been a big seller, likely because of the price tag. Still, the headset market is expected to grow quickly over the next several years, and Apple is already working on new versions of the Vision Pro, including one that’s more affordable than the original.

Jon Rettinger, a tech influencer with more than 1.65 million YouTube subscribers, says he’s not overly enthusiastic about VR/AR just yet. «It’s heavy, invasive and without a must-have use case,» Rettinger told CNET. «If the technology can go from goggles to glasses, I think we’ll see a significant rise. But if the current form factors stay, it will always be niche.

The YouTuber loves that the technology exists, but still doesn’t use it. «The honeymoon wore off. Aside from some gaming and content viewing, it’s still cumbersome, and I tend to go back to my laptop,» he said.
