可扫描人脸解锁书本的书皮

We've all been told you should never judge a book by its cover. Now one creative agency has found a way to prevent that from ever happening – by creating a cover that judges you.

常言道，仅凭书的封面无法判断一本书的好坏。如今，一家创意公司就找到了一种方法防止此类事件发生——让封面来判断你。

Amsterdam design studio, Moore, has created a book jacket that will open up when a reader shows no judgement about the novel.

The cover uses an integrated camera and facial recognition system to scan the reader's face, and only unlock the book if the expression is neutral.

Any other expression - even one that shows over excitement - will cause the book to remain firmly locked.

The prototype book, dubbed 'The Cover that Judges You,' is currently filled with creative work for the Art Directors Club Netherlands annual.

According to Dezeen, the camera is placed at the top of the cover, above a screen that sends back the image when it detects a face.

Artwork featuring abstract facial features is displayed on the cover so that the user can line up their own features in the correct place.

A neutral expression triggers an Arduino micro-controller which unbolt the lock.

'My aim was to create a book cover that is human and approachable hi-tech,' explains designer Thijs Biersteker on his website.

'If you approach the book, if you're overexcited or your face shows a sceptical expression, the book will stay locked.'

'But if your expression is neutral (no judgment) the system will send an audio pulse and the book will unlock itself.

'I often worry about my scepticism and judgement getting in the way of my amazement.

'Judgment should never hinder the relentless enthusiasm of seeing things for the first time.'
