The perfect gaming interface: your heart

The time has come to put not only your soul into a game – but also your heart…

One of the stupidest things I've ever done is walking into a bathroom and almost having a heart attack colliding head first with another person as they left. As I moved my hands up to apologise, they did the same, and for a brief second my mind – fuelled by a lifetime of violent action movies – thought that I was about to be attacked.

It was in the Gherkin after all – London’s iconic skyscraper. Perhaps a double agent had mistaken me for one of Boris' assistants and was looking to infiltrate the offices of the floppy-haired London Mayor by stealing my identity.

What actually occurred was far more boring. I turned a corner and walked head-first into a full length mirror. In my defence, it was a stupid place to have one but that didn't stop the brief spike of adrenaline from kicking my heart into overdrive.

The reason for this embarrassing, barely-relevant anecdote is because a) I've been meaning to get it off my chest for some time and b) I've been thinking about hearts and their potential role in video games.

I'm not referring to pixellated hearts which top up virtual health bars. I'm talking about the miraculous 100% home-grown pump that, as you read these very words, is delivering a steady flow of oxygen to all the cells in your body. Hopefully.

Too sensible for you? How about: intelligent horror

I'm an utter wimp when it comes to horror games. Headshotting aliens in Halo and Destiny? No problem. Trapped in an abandoned mental asylum littered with the howling spirits of little girls with long black hair however?

No. No thank you. That doesn't mean I can't see the potential of using our heart rates to create intelligent horror games. Using a camera like the Kinect, or even a connected smartwatch with a built-in heart rate monitor like the upcoming LG G Watch R, horror games can bring out the scares at the best possible time.

If your heart rate is normal, thanks to your impressive steely nerves, then that will be the perfect queue to ram a wailing banshee in your face the next time you open a door. It can work with puzzles too. Imagine if the next Call of Duty title has a level in which you have to diffuse a bomb solving a puzzle and cutting the right wires.

The faster your heart rate, the shakier your on-screen hands become and your vision could blur, rewarding calm nerves with becoming a hero.
