Lenovo’s latest tablet computer can take a digital copy of handwriting as it is jotted down on a paper notepad placed on top of the machine.
The Yoga Book’s unusual fold out digitiser pad can also be used to create graphics. In addition, it lights up to form a keyboard.
The tablet bucks a trend among rivals that encourage users to write and draw directly on their screens.
One expert said that pursuing a unique approach was “risky”.
“There have been previous concepts like this Microsoft toyed with something similar years ago – but it’s very different to what else has actually been put on sale,” said Patrick Moorhead, from the tech consultancy Moor Insights & Strategy.
“And when you bring out something new there’s a risk.
“That’s not necessarily bad, because there could be a higher rate of return [if it proves popular] and people recognise Lenovo as a company that brings out differentiated products.
“But if it doesn’t deliver, then the spending on all the [research and development] will have been for naught.”
Lenovo made its announcement ahead of the start of the Ifa tech show in Berlin, where it will show off the product.
It comes in two versions: one powered by Android, the other – which costs more – by Windows 10.
Lenovo refers to the lower digitising half of the device as a “create pad”.
A button-press illuminates a “Halo” keyboard on its flat black surface, allowing owners to use it like a laptop.
It provides haptic feedback – a buzzing sensation – when each key is tapped. But the letters, numbers and symbols are fixed and do not change shape.
The firm acknowledges that owners will probably be slower at typing on it than on the keyboards sold as accessories for Apple’s iPad Pro, Microsoft’s Surface and Samsung’s Galaxy Tab devices, all of which feature moving parts.

But Lenovo says that new owners should still be able to attain speeds of 40 to 60 words per minute and then improve over time.
As such, consumers could get the same benefit from taking a photo of their notes with a normal tablet or smartphone.
Lenovo suggests the facility will have most appeal to students, but also intends to target the tablet at bloggers, business executives and people working in creative industries.
“You get benefit from Lenovo’s pen input, and the device is also a lot thinner than Microsoft’s Surface,” said Mr Moorhead.
