Sony wants to put WHAT in your mouth?

2 min read


Remember when Nintendo showed off its vitality sensor? It was meant to be a biometric you stuck your finger into, so that games could read your emotional state, and alter the game based on your heart rate. It would take something Like Left 4 Dead’s AI director and make it a million times more effective. It was a silly idea then, and we all laughed. The device never came to fruition. And now, Sony’s patented something quite similar. Only substantially crazier. It goes in your mouth.

This comes via a Sony Computer Entertainment of America patent filed two years ago, but published yesterday by the US Patent Office.

A small sensor would fit behind your front teeth and detect the changes in hormones and chemicals in your saliva. This would allow it to ascertain your psychological and emotional state, and then throw more bad guys at you in your videogames.

"Emotion recognition or understanding the mood of the user is important and beneficial for many applications; including games, man-machine interface etc.," the patent states. "Emotion recognition is a challenging task due to the nature of the complexity of human emotion; hence automatic emotion recognition accuracy is very low."


It would work in conjunction with a suite of other sensors – like a ring to measure your heart-rate and a head-cap to measure brain activity. this would all work together with the biometric sensors that were originally part of the PlayStation 4’s controller – before Sony wisely abandoned the idea.

I’m all for innovation, but having gaming accessories that go in your mouth? No thanks.

Editor. I'm old, grumpy and more than just a little cynical. One day, I found myself in possession of a NES, and a copy of Super Mario Bros 3. It was that game that made me realise that games were more than just toys to idly while away time - they were capable of being masterpieces. I'm here now, looking for more of those masterpieces.
