In the journey to create what we currently know as the DualShock 4 controller for the PlayStation 4, Sony went through a number of designs, including one that featured biometric sensors that read a player’s emotions. The controller would have had biometric strips that measured skin conductance to get data on a player’s state of mind.
In an interview with Stuff, chief PS4 architect Mark Cerny said the controller was a “long research project where we looked at pretty much any idea we could think of.” Instead, Sony opted for a more traditional style of controller that was optimized to play first person shooters, which are some of the most popular games on the market. Cerny said that in the past the DualShock was not ideal for playing FPS games, and they wanted to fix that with the final design for the DualShock 4.
“Historically we have heard many times that our controllers have not been ideal for first-person shooters, so we wanted to make sure we had something that would be much better for that genre,” Cerny said. “We tested the throw of the triggers, the position of the triggers, how much pressure it takes. We looked at the joysticks, the dead spot, we looked at convexity and concavity.”
The end result, he says, “Feels extraordinarily natural.”
