Typing and communicating with PS4?

[ReplicaX]

I used a simple Wii wireless kb and logitech wireless mouse. I strongly suggest a self powered USB hub if you want more USB ports and has more available power for multiple devices.

As far as PTT for TS3/Vent/Mumble I have seen ppl use in other console games a PTT USB foot switch /w a laptop.

If you don't want to hook up a keyboard in your living room you can use your smart phone/tablet to enter text in the game. It's much faster than selecting letters with the D-Pad but a real keyboard is still the most efficient way to communicate.
