DualShock 4 touchpad works much like that on a laptop, will be used for Diablo III
The PlayStation 4 controller's touchpad is clickable, and will be used for inventory management in Diablo III.
Gamespot confirmed the news on the showroom floor, which is the first chance the public has had to experience the new controller with its novel touchpad.
Though this isn't necessarily a surprise, it's the first confirmation that the touchpad will behave more like that found a modern laptop than other touch interfaces.
Sony declined to go into further detail, and only Blizzard has opted to reveal how they plan to use the feature.
