DualShock 4 Designed Around FPS Comfort
PS4 system architect Mark Cerny has revealed that Sony toyed with the idea of making a Biometric PlayStation 4 controller that measured skin conductance and galvanic response, but dropped the idea in favour of the DualShock 4, which was designed with first person shooters in mind.
In an interview with Stuff, Cerny stated that the PS4 controller was subject to "a long research project where we looked at pretty much any idea we could think of".
"Would it help to measure the galvanic response of the skin?," he posited. "We tried out a tremendous number of things - and then we went to the game teams to ask them what they thought they could use from the controller."
Biometric feedback could theoretically be used to measure player stress levels, factoring into games with AI directors (such as Left 4 Dead). Ultimately, though, the team opted to stick with a more traditional design, based around providing a comfortable FPS experience.
"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 continued. "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."
"I haven't heard a negative comment about it yet. For a controller with a very different form factor that was just amazing to see."
Matt recently tested the DualShock 4, describing it as a "comfy little fellow" but still bemoaning the central thumbstick positions.
