Lead system architect at Sony, Mark Cerny, has revealed in an interview that the company had considering making the DualShock 4 controller for PS4 capable of measuring a gamer’s stress levels. This would be done by measuring their skin’s galvanic response, which basically reveals how conductive the skin is at any given time. Conduction varies with how much the gamer is sweating, the technique of galvanic skin response is used in polygraph tests for lie detection.
Cerny says that Sony had a long research project in which it looked at every possible idea, and that they tried out “a tremendous number of things.” After consultations with the game teams, the idea to make controllers able to determine stress levels was scrapped. Cerny also acknowledged that PlayStation controllers haven’t always been ideal for first-person shooter games in the past, this is something that they focused on when developing the DualShock 4 controller. He says that the new controllers will feel “extraordinarily natural” when playing FPS games on PS4, thanks to new joysticks and improved triggers. Sony is going to release PlayStation 4 this holiday season, the DualShock 4 controllers will be available alongside the console.
