Apple not solely included three cameras within the iPhone 12 Pro and the iPhone 12 Pro Max, however the firm additionally added a lidar sensor. The new characteristic, a primary on iPhones, helps enhance portrait mode photographs and even makes it potential to take these blurry-background photographs in evening mode. The lidar sensor, nonetheless, has one other trick it might probably do — and it is certain to impress your pals at your subsequent occasion (when it is protected once more, in fact).

Lidar stands for “gentle detection and ranging” and it really works by bouncing lasers off of objects to measure their distance, based mostly on how lengthy it takes for the sunshine to get again to the sensor.

Here’s one occasion trick I simply found, with the assistance of MacRumors, and I lay out just a few extra beneath.

For my first trick, this is how one can use the iPhone 12 Pro’s digicam to measure an individual’s peak in simply a few seconds (I did this with my children and so they liked it).


Pretty cool stuff, proper? 


1. Open the Measure app in your iPhone. 

2. Point the rear digicam at an individual who’s both standing or sitting and be sure to get their complete physique — from head to toe — within the body. 

3. After a second or two, a line will seem above their head with an estimate of their peak, together with gadgets like their hair or a hat. 

4. You can take an image of the measurement with a faucet on the shutter button, saving it to your digicam roll. 

In my testing, the measurement was correct inside half an inch. My son’s curly hair brought about his first measurement to be simply barely too excessive, however after he combed it down, it was spot on at 4 ft, 7.5 inches. 

I additionally examined it on myself, and small issues just like the angle of my head or carrying a hat resulted in the identical barely brief 5 foot, 9 inch studying. When I stood straight up, nonetheless, trying instantly on the digicam and not using a hat on, it was extra correct, with a 5 foot, 10 inch studying. 

You can get a tough estimate of greater than only a particular person’s peak with the Measure app. You can use it to get the size of a bit of furnishings, for instance, to see if it’s going to match via a door. I lately measured a TV to settle a debate on whether or not it was 55 or 65 inches (it was 65). 

When the Measure app first launched with iOS 12, I defined how one can use it to measure random family objects or determine sq. footage. With the addition of lidar on Apple units, the app is getting extra correct. So when you’ve upgraded your iPhone, it is value giving the Measure software one other shot.

Want to attempt extra enjoyable lidar options?

The lidar sensor is not restricted to only measuring completely different objects. You can use it to create 3D maps of a room (as proven above), or a 3D recreation of a single object, which you’ll then print out on a 3D printer once you use an app like Polycam. 

According to ’s Scott Stein, the Apple Arcade recreation Hot Lava makes use of the lidar sensor to scan a room, after which he might cover digital stuff behind actual gadgets within the room, like a chair. 

As extra apps are up to date to enhance the augmented actuality expertise due to the lidar sensor, there isn’t any telling what else we’ll have the ability to do with appropriate iPhone and iPad fashions. 

After impressing your family and friends along with your iPhone 12’s ($829 at Amazon) enjoyable trick, be sure that to take a look at these hidden options in iOS 14. If you are still studying your approach across the iPhone 12, listed below are some settings value looking at.
