There's a nice cheap 20$ keyboard that fits right into the ps4 controller. Easy set up and it's a mini keyboard. Will need a new solution if The Move is actually introduced into this game
Wow, it's about time they come out with a controller mounted keyboard for the PS4 (I just looked up pictures). I think the motion controls are the best alternative to the keyboard. I can type pretty fast with the sixaxis motion control.
I bought a small one that connects to the controller but I am mostly just going to use the chatpad as a keyboard, without connecting it for reasons and preferences. Mostly connected to the fact the headphone jack connects better to the controller then the Chatpad. Its a Nyko but I suspect others might want to look into them on the whole, it suggests or I suspect it has a mic, it also has a speaker and a few other things. But all and all it is just to make it easier to name animals and planets. Rather then using the controller every time. The only issue is it removes the auto-correct which means it more or less removes the spell check on the over all process.
