Playstation Lifestyle asks this question and gives an idea of what Sony should do with the PS4 main controller the DualShock 4 (it's been over 17 years, the controller has stayed mostly the same). What they ask to their readers is this, "Should Sony add a back touchpad to the DS4?"

I thought to myself this wouldn't be a good idea, because I hold my DualShock 3 in many different ways. Most of which have me touching the back bridge of the controller. After handling my DS3 while playing games like NBA Jam, Dungeon Defenders and Kingdoms of Amalur (demo) I tried to pay attention to what my natural position was. My middle fingers usually find their way to the back of the controller, leaving my pointer fingers on the L1 and R1 buttons. It's just natural for me I guess.

Once I tried keeping my middle fingers on the L2 and R2 buttons I didn't have to worry about affecting something like a touchpad back there if I held the controller like I was suppose. But again I thought, my natural way of holding the controller shows I could use the touchpad. What if developers placed the usual R3 and L3 buttons onto the right and left segments of the touchpad, leaving the the original R3 and L3 buttons to become new buttons themselves.

For my own idea I think the controller should stay the same price as it is now (they make a killing profit off of those controllers now anyways), but add a built in microphone. The PS4 should have voice command from the start.

Anyway, what do you all think Sony should do with the DualShock 4? Keep the design and improve upon it or trash it and start something completely new after 18 years of the same design.

If anything, they could earn themselves some Vita sales by making it the only possible controller...

Yeah, jk. =P

Improve the size of the controller is my ony wish really, I find it uncomfortably small.

What I don't want Sony to do is just make the controller bigger. I like the size of the controller, but to effectively add something like a back touchpad they should make it a little bit bigger. Maybe 2 cm longer? I'm not sure, I would have to do some dimension tests before going any further.

change the sticks to concave and a tad bit more flexible. R1/2 and L1/2 needs to be a bit more accommodating. D-pad is good as it is for me personally. And on top of all this I would like if it they try and incorporate something new to it..maybe use the trackpad tech used on the psv on the handles or the back or something..could lead to some interesting possibilities

Also how about a trigger of some sort..at the bottom instead of a track pad? something that can be used via our ring fingers?

The Dual Shock 4 should take some ques from Nintendo and Microsoft. Swap the d-pad and the left joystick. Give the joysticks concave tops rather than convex. Add real triggers. Replace the four button style d-pad with a real plus + shaped one. Make it a little bigger so it fits adult hands better. Change the shape so it doesn't jab into the palms of your hands.

While we're on the subject, I'd like Nintendo to recombine their controller instead of the Wii-Mote Nun-chuck combo. I don't care if it's designed to come apart into two controller so long as I can play regular games without having to get out a second controller. Yes I'm aware that the Wii U is going to have that giant tablet controller with the twin sticks. But rumors suggest that at most the system will only work with two of them and that it will use regular Wii controllers when your not using the tablet controller. I just want Nintendo to give us more standard shaped controllers again.

As for Microsoft. I want built in rechargeable batteries. A standard plus shaped d-pad, and flat face buttons. Other than that it's nearly perfect.

Triggers for L2/R2, make it slightly bigger, like 10% bigger. Perfect.

I'm not really into the ''more is better'' on controllers, I like them as they are now, I don't really want more gadgets on them... Maybe I'm old fashioned that way...

They should make it a tablet controller, naturally.
