File this one under things that are . . . quite interesting. A group of scientists over at MIT invented a prototype book [1] — this one's appropriately called The Girl Who Was Plugged In — that is supposed to mimic the emotions of the main character in the story.

Here's how it works: the book comes covered in glowing LED lights that brighten or dim as the plot changes. As if that weren't enough, the book hooks up to a vest that you're supposed to strap on and wear while you're reading. That vest also mimics the characters' feelings like love or deep sadness.

So, you'll feel vibrations when a character's heart rate would, or should, go up, and you'll feel heat at your collarbone in a dramatic situation. Oh, and get this: the vest comes with airbags that tighten and loosen depending on the scenario.

For all intents and purposes, this could be a cool way to merge reality with fiction, but the execution is definitely questionable. Imagine reading The Fault in Our Stars [2] or some other intense book hooked up to that thing. Nevermind, we don't even want to go there.

Let us know what you think: is it weird or wonderful?
