DefinitionHover (ホバー) is the state in which the mouse pointer rests over an element on the screen, such as a button or link, without clicking it.
ExplanationBecause hover comes before the press, it gives the system a clue to which element the user is looking at. The system can use this state as a cue to respond, for example by changing the element's color or showing a short note such as a tooltip. A touch screen, operated by touching it directly with a finger, has no stage of resting a pointer, so guidance that relies only on hover may not reach the user.
AnalogyIt is like resting a fingertip on the spine of a book on the shelf without pulling it out yet.
Memory hookIn English, hover describes a bird or helicopter staying still in midair. Link it to the pointer floating motionless above an element.
