Drag to move
It works like this:
The user performs a longpress on an item in the screen
The item gets selected and the user can move it around the screen by holding on to it.
When the user releases the item on an empty spot, the item is located there. The spot where it was before, is now open. It is also possible that the item changes position with an other item.
The drag to move gesture can be used when the user must be able to move objects around the screen. For instance to alter the order of a music playlist, to (re)arrange the home screen, or to enter a value using a slider.
- It is fun to do
- It is an intuitive way of playing with objects: tap and hold and drag
- Direct manipulation, which gives user a sense of control. (Borrys Hasian)
- The user has to find out that the item can be moved around, by trying
- Much better if the open space is automatically filled by the item next to it. (Borrys Hasian)
