or rather the sliding control in those wheels. Specifically platformer/ action games. The problem is having virtual buttons that you have to take your finger off one button and lay it down on the next. Everytime you take your finger off, it takes a small spot of concentration to place them down in the right location so that you don't go off the buttons. I always thought the problem should be rectified by having larger buttons or hotspots, . Now I realize the real problem is that you shouldn't have to take your finger off the pad. On regular controllers (like the PS3 Dual Shock of 360 controller), you do take your fingers off to move to another button, but when the gameplay gets really intense you tend to slide them over. It works out cause after a while you remember where they are. On a virtual screen obviously this is harder The thing about iDracula though is that in using the wheel, you slide to the direction you want to go: what keeps you oriented is your character's actions. So instead of you checking that your fingers are in the right spot, all you have to do is make sure you don't move off the controller area, which is a lot easier and doesn't require you to take attention off what you are doing. So in a platformer, while pressing right to go forward, you simply slide up to make your character go up a ladder, instead of taking your finger off "Right" and pressing "Up". Most games require you to take your finger off one button before you activate another. I suggest devs implement this slide idea to make these games easier.
