Your iPhone Pro and iPad Pro may have a helpful and powerful feature you might not know about. Built directly into the last few generations of devices, the Light Detection and Ranging (LiDAR) scanner emits a laser to measure the distances of surrounding objects. This feature provides a few key benefits.

First, LiDAR helps the camera take sharper photos, particularly in dark conditions. Second, the scanner taps into AR, or augmented reality, to combine the real and virtual worlds. With AR, your phone or tablet acts as a virtual tape measure, shows you how new furniture would look in your home, scans and recreates 3D models, and immerses you in AR games.

Introduced a few years ago, the LiDAR scanner is available on the Pro and Pro Max models of the iPhone 12, 13, 14, and 15, as well as the 11-inch and 12.9-inch iPad Pro models from 2020 and later. Nestled among the rear cameras, the scanner can detect objects up to five meters, or 16.5 inches.

1. Take a photo in the dark

Snapping a sharp photo with your iPhone can be challenging, especially in low-light situations. Under those conditions, the LiDAR scanner detects the distance of your subject, allowing your camera to power up the autofocus quickly.

Apple claims that the LiDAR sensor helps the camera autofocus as much as six times faster, an advantage when you want to take a shot before it’s too late. There’s no need to do anything special. Aim your phone’s camera and the LiDAR automatically kicks in if necessary.

2. Measure distances

You need to measure a physical distance but don’t have a ruler or tape measure. There’s no need to worry when you can use a virtual measure. Included with iOS/iPadOS and downloadable from the App Store, Apple’s free Measure app can determine the distance between any two points, display the dimensions of an object, and tell you if a surface is straight.

Open the Measure app on your device. Then to measure the distance between two points, position your phone so the starting point is at the dot within the circle.

Tap the plus icon, move your phone along the area you want to measure, and then tap the plus icon again. The distance appears on the screen.

To measure an object such as a square, you position your phone in the same way. Tap the plus icon and move your phone along the first area to measure it. Then double tap the plus icon. Move your phone to capture the next area and, once again, double-tap the plus icon. Continue this way until you’ve captured the entire object. Double-tap the plus icon at the endpoint, and the distance appears for all four sides.

To determine if an area is level, tap the Level icon in the app’s toolbar. Tilt your device horizontally or vertically along a surface until the screen turns to 0 and flashes green to indicate that you’re level.

Beyond using Apple’s Measure app, check out other free AR measuring apps from the App Store, including Tape Measure and AR Measure.

3. Try out furniture in your home

Are you looking at a new desk, chair, table, or other piece of furniture and wondering how it would look and fit in your home? Let the IKEA app give you a helping hand.

Start by browsing or searching for a specific piece of furniture or other item, including chairs, beds, desks, sofas, lamps, mirrors, clocks, dressers, or bookcases. When you find an item that interests you, select it and tap the View in room button. Choose an area in your home where you’d like to see the item. You can then move the item around the room by dragging and dropping it. When it’s in the right spot, tap the shutter button to snap a picture.

A few other apps that let you virtually position and view furniture in your home are Wayfair, Housecraft, and Bob’s Discount Furniture.

4. Scan a room

Maybe you’re redecorating an entire room and want to measure it to help with your home improvement efforts. One app up to the task is Canvas: LiDAR 3D Measurements.

After signing up for a free account, start a new home project, give it a name, and then kick off your scan. Move your phone to capture every nook and cranny of the room you want to measure. When done scanning, tap the checkmark, and you can view the scanned area and save or share the scan itself.

5. Try on glasses

Need a new pair of prescription glasses or sunglasses but want to check out some options before you head to the store? The Warby Parker app will let you try on virtual glasses to see how they look. Browse the different glasses on display in the app. Spot a pair you like and swipe down from the top of the screen for the Virtual Try-On feature. The glasses automatically appear on your face, where you can check your appearance.

6. Hear your environment described

Designed for people who are blind or sight-impaired, Microsoft’s Seeing AI acts as a talking camera able to analyze and describe nearby people and objects.

After launching the app, tap one of the icons at the bottom for the item you want to be described, choosing from short text, a document, a product, a person, currency, or a scene. Tap the shutter button and the app shows text and provides a spoken description of the item.

7. Scan a 3D model

If you want to capture a 3D image of an object in the real world, Scaniverse – 3D Scanner is an effective tool. Fire up the app, tap the shutter button, and then select the size of the object you want to scan — small, medium, or large. Move your phone around the object to capture as much of it as possible. Tap the shutter button when you’re finished. Ten choose how you want to process the scan. You can view the scan of the object by moving it around the screen and then edit and share the scan.

Other 3D AR scanner apps worth trying include 3D Scanner App, Polycam – LiDAR & 3D Scanner, and ARama!

For the longest time, type 1 diabetes was known as a childhood disease. Even until recently, it was still called “juvenile diabetes.” I’m here to tell you that just because you’re an adult doesn’t mean you’ve escaped the wrath of this illness.

I know this because it happened to me. At the age of 30, I was misdiagnosed with type 2 diabetes for over six months. It wasn’t until I started sharing my diagnosis on TikTok that I discovered the truth and that this could happen to someone my age.

Roughly 60% of diagnoses today occur in adults who are 20 years of age or older. This form of type 1 diabetes is called Latent Autoimmune Diabetes of Adults. On top of that, 90% of those diagnosed with type 1 have no family history. 

Rates for people living with diabetes are expected to more than double to 1.3 billion by 2050. This will impact both people with type 1 and type 2 diabetes. Spreading awareness about symptoms and early screening for type 1 diabetes will help people get the correct diagnosis and treatment they need sooner.

There is a lack of awareness about diabetes, even within the medical community. Because of this, many people go undiagnosed or misdiagnosed with type 2 diabetes for months or even years. Here’s what you need to know.

The difference between type 1 and type 2 diabetes

Type 1 diabetes occurs when the pancreas no longer produces insulin, the hormone that regulates blood glucose, because the immune system attacks itself. Meanwhile, type 2 diabetes occurs due to insulin resistance, often due to lifestyle factors, and tends to be hereditary. As many as 11% of patients diagnosed with type 2 diabetes might actually have LADA. There are a couple things we can all do to prevent others from going undiagnosed and feeling ill for as long as I did. 

The first is to know the signs of type 1 diabetes. The tell-tale symptoms are excessive thirst and urination, extreme feeling of fatigue, blurred vision and weight loss. When I was diagnosed, I was experiencing all of these symptoms and had lost over 20 pounds. After months of misdiagnosis, I saw an endocrinologist who ordered blood tests, and within weeks, I had the correct type 1 diagnosis.

Had my glucose levels gone unchecked for longer, I could have gone into diabetic ketoacidosis or DKA, which can be deadly. Up to 30% of those diagnosed in the US are discovered at this stage. 

Another way we can prevent loss of life or sickness is with early screening for indicators of type 1 diabetes. Two blood tests are used to aid in diagnosis: A c-peptide test, which measures how much insulin a person is making themselves, and an islet autoantibody test, which screens for markers of the autoimmune process associated with type 1 diabetes. With these results, people can prepare and seek out treatment to offset the disease and/or treat it.

New legislation could help

Recent legislation aims to bring early screening for type 1 diabetes to the forefront of preventative care.  

Last month, a bipartisan bill called the Strengthening Collective Resources for Encouraging Education Needed for Type 1 Diabetes Act was introduced in the House of Representatives. The bill directs the Centers for Disease Control and Prevention to conduct a national campaign to increase awareness and knowledge of type 1 detection, screening and management, and will allocate $5 million to the CDC to carry it out.

On my end, I will continue to share my story through articles like this one, videos on social media and interviews on my podcast, Diabetech. My hope is that no one will experience the long stretch of illness I experienced before getting the correct diagnosis and treatment needed.

Diabetes is a complex and complicated disease to manage. Devices like insulin pumps, smart insulin pens and continuous glucose monitors make living with the disease easier to manage, but they come with a steep learning curve. 

I’m fortunate to be able to interview experts in the field on my podcast who help me and my audience stay informed on the latest tools and technology. I encourage anyone living with this disease to connect with me on YouTube, Instagram or TikTok to feel less alone and more in charge of your personal health.

Midjourney, a popular AI-powered image generator, is creating images of Donald Trump and Joe Biden despite saying that it would block users from doing so ahead of the upcoming US presidential election.

When Engadget prompted the service to create an image of “the president of the United States,” Midjourney generated four images in various styles of former president Donald Trump.

When asked to create an image of “the next president of the United States,” the tool generated four images of Trump as well.

When Engadget prompted Midjourney to create an image of “the current president of the United States,” the service generated three images of Trump and one image of former president Barack Obama.

The only time Midjourney refused to create an image of Trump or Biden was when it was asked to do so explicitly. “The Midjourney community voted to prevent using ‘Donald Trump’ and ‘Joe Biden’ during election season,” the service said in that instance. Other users on X were able to get Midjourney to generate Trump’s images too.

The tests show that Midjourney’s guardrails to prevent users from generating images of Trump and Biden ahead of the upcoming US presidential election aren’t enough — in fact, it’s really easy for people to get around them. Other chatbots like OpenAI’s ChatGPT, Microsoft’s Copilot, Google’s Gemini and Meta AI did not create images of Trump or Biden despite multiple prompts.

Midjourney did not respond to a request for comment from Engadget.

Midjourney was one the first AI-powered image generators to explicitly ban users from generating images of Trump and Biden. “I know it’s fun to make Trump pictures — I make Trump pictures,” the company’s CEO, David Holz, told users in a chat session on Discord, earlier this year. “However, probably better to just not — better to pull out a little bit during this election. We’ll see.” A month later, Holz reportedly told users that it was time to “put some foots down on election-related stuff for a bit” and admitted that “this moderation stuff is kind of hard.” The company’s existing content rules prohibit the creation of “misleading public figures” and “events portrayals” with the “potential to mislead.”

Last year, Midjourney was used to create a fake image of Pope Benedict wearing a puffy white Balenciaga jacket that went viral. It was also used to create fake images of Trump being arrested ahead of his arraignment at the Manhattan Criminal Court last year for his involvement in a hush money payment made to adult film star Stormy Daniels. Shortly afterwards, the company halted free trials of the service and, instead, required people to pay at least $10 a month to use it.

Last month, the Center for Countering Digital Hate, a non-profit organization that aims to stop the spread of misinformation and hate speech online, found that Midjourney’s guardrails against generating misleading images of popular politicians including Trump and Biden failed 40% of its tests. The CCDH was able to use Midjourney to create an image of president Biden being arrested and Trump appearing next to a body double. The CCDH was also able to bypass Midjourney’s guardrails by using descriptions of each candidate’s physical appearance rather than their names to generate misleading images.

“Midjourney is far too easy to manipulate in practice – in some cases it’s completely evaded just by adding punctuation to slip through the net,” wrote CCDH CEO Imran Ahmed in a statement at the time. “Bad actors who want to subvert elections and sow division, confusion and chaos will have a field day, to the detriment of everyone who relies on healthy, functioning democracies.

Earlier this year, a coalition of 20 tech companies including OpenAI, Google, Meta, Amazon, Adobe and X signed an agreement to help prevent deepfakes in elections taking place in 2024 around the world by preventing their services from generating images and other media that would influence voters. Midjourney was absent from that list.
