Click on touch interfaces
It’s not possible to click things on the touch interface because you don’t know when you pressed the screen hard enough. And if you add animation to the button that you click, you will most likely not see it, because your finger is on the way. Adding other reactions, such as vibration of the phone or waves of drawing on the screen, may work, but usually there is too much delay, far exceeding the tangible touch of a button. Therefore, until they come up with a screen with buttons that can be pressed, all touch devices should move in the direction of dragging user interfaces (DUIs).
The counter is intuitively easier to click on the object on the screen, drag it, and then release it, and just click and release. This is probably due to the fact that you can move around the object when you start to drag, and you can adjust the pressure while dragging it. Dragging also has a lot more options, because now you have a direction, not just the point you clicked. You can do different things if the user drags an object in different directions. Speed ​​can also be used, as well as the point at which the user frees the object. The exit point is the real power of DUI, because it is very easy to release something, even with pixel precession.
Some projects have started using DUI, for example (here we go) iPhone, Palm Pre and Android phones. But only part of their design is DUI, the rest is a click. One area that they are all associated with is the keyboard. Instead of pressing a key, the user presses any key, and then drags them with a finger to the key that they really wanted to press. Unlocking these phones also uses drag and drop.
Other easily implemented DUI functions will be things like mouse gestures, where dragging in different directions or drawing different shapes does different things. Alternative keyboard research is also underway that focuses more on drag and drop. All buttons can be replaced with switches, so you need to drag them a little to click on them. With well-designed graphics, this should also be intuitive for the user.
