The most useless technological advance of all? Lenovo presents a laptop with & # 039; hit to unlock & # 039; characteristic

The opening function of the Yoga Book C930 may seem like a totally superfluous tool, but without it, Lenovo says the $ 1,000 laptop would be too difficult for most users to open.

Move, facial recognition.

Lenovo on Thursday unveiled its latest laptop, the Yoga Book C390, which has a strange way of unlocking the device.

When the laptop screen is closed, users give the top of the device two taps and it will open.

It may seem like a totally superfluous feature, but without it, Lenovo says the $ 1,000 laptop would be too difficult to open for most users.

The firm worried that the ultra-thin aluminum construction of the Yoga Book C390 could hinder the users' opening, so they added the peculiar characteristic of hitting to unlock.

& # 39;[Lenovo engineers] he realized that in something so fine … that for most people who do not have longer nails, it was going to be a bit difficult to open, "said Kevin Beck, senior senior analyst at Lenovo, in a livestream announcement at the IFA annual technical conference in Berlin.

Leaving aside all the jokes, Lenovo says he reflected a little on the mechanics behind it.

The Yoga Book C930 uses an accelerometer, or motion detector, that detects when users touch the laptop.

That sends a current through the "memory metal" of the device, which extracts two magnets from the alignment and causes the top part to open.

"As you can imagine, this took a lot of time to fine tune," explained Beck.

"We did not want it to open if you accidentally hit the table, so having the right sensitivity and balance … that took a while."

It's true that it's a pretty unique way to unlock a device. However, it did not impress everyone on Twitter.

"You can not think of a single circumstance in which it would be more useful to hit", said one user He said.

Other he joked that would only be useful when the laptop has a "badly designed" case already.

Others pointed out that it is "much faster" to open the computer yourself.

Still, apart from the somewhat eye-catching feature to open, the Yoga Book C930 is a solid laptop.

Its ultralight and portable design makes it ideal for trips or students.

The laptop has a "bag mode" so that it does not accidentally open when placed in a certain position, or if it is pushed into a backpack.
