Playstation had a hard time competing with other companies in the field of the controller. The PS3 controller did not give the best feel in the gamer’s hand. It felt light, and delicate, and sort of toy like. The issue mainly arose while playing a first person shooter. Obviously this was a major issue since a massive majority of the gaming market includes first person shooters.
"Historically we have heard many times that our controllers have not been ideal for first-person shooters, so we wanted to make sure we had something that would be much better for that genre,"
Playstation has taken this into consideration and created a much more futuristic design, feel, and gone way beyond that as well.
"We tested the throw of the triggers, the position of the triggers, how much pressure it takes. We looked at the joysticks, the dead spot; we looked at convexity and concavity. [It] feels extraordinarily natural."
With all of that included, they have also included an LCD touchpad in the central area on the controller. This opens a massive door for game developers. With this touchpad, Playstation has created room for a plethora of possible innovations in gaming. Game developers can create an infinite amount of new controls with quick finger movements across the touchpads. They can go anywhere from doing a slicing movement, as if you’re playing Fruit Ninja, to attack with your sword to using thumbs from both hands to open a door. And there are so many other possibilities and they games should keep that in mind to at least add a feature in to where you, the player, can create your own controls. The issue I see with this is that Xbox does not have this touchpad, therefore any games that tried to take advantage of the touchpad would be restricted to the Playstation audience. But Playstation could also rack up more exclusives as they are already known for with great games such as God of War and The Last of Us.
Another idea that they had with the new controller was to include galvanic technology to measure the amount of sweat your hands give off to measure fear or intensity at any moment while playing. PlayStation 4 architect Mark Cerny revealed the feature while discussing the DualShock 4's evolution with Stuff.
"We had a long research project where we looked at pretty much any idea we could think of," Cerny explained. "Would it help to measure the galvanic response of the skin? We tried out a tremendous number of things - and then we went to the game teams to ask them what they thought they could use from the controller."
This feature ended up being excluded from the final product. A possible problem from measuring clamminess is that each human being reacts in different measurements. One may not be fearful but just have really clammy palms opposed to someone that is terrified but just has really dry hands.
This feature may come up again in products if they decide to release a controller in the future that you can purchase separately.
