Valve is preparing to support the PlayStation DualShock 4 controller in Steam. The revelation came during the developer conference, where Valve’s Jeff Bellinghausen presented information about the new Steam Controller API.
According to Bellinghausen, the DS4 has a lot of overlap with the Steam controller in terms of functionality. Both have touch control surfaces and built-in gyroscopes. However, he admitted that native support for the DS4 is a bit weak; which is why Steam is being designed to communicate directly with the controller itself.
This should essentially mean that people will be able to connect their PlayStation 4 controller to the PC and play games without requiring any additional software. At the moment, the only way to get the two devices to work together is with keyboard emulators.
Valve is also planning to support other controllers, although the company is not ready to share additional details about it.
