The present disclosure relates to a method and an apparatus for providing a user interface. More particularly, the present disclosure relates a method and an apparatus for providing a user interface that improves recognition of a user by displaying a position of an input in a state of hovering.
Recently, a vehicle is equipped with a display in a touch screen for displaying control menus of electronic devices. The touch screen has a user interface (UI) to recognize an input of a finger and the like. The input may be a direct contact of the finger or a non-contact input such as hovering.
However, the touch screen displaying the control menus of the electronic devices does not display the input. Accordingly, selecting the control menus may not be intuitive, thus deteriorating user convenience in operation of the electronic devices. Moreover, the user interface, which does not accurately recognize the input, may affect driving safety when the driver operates the control menus while driving.
Thus, the input should be easily recognized and manipulated to prevent distraction of a driver's attention. The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention, and therefore, it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.

According to an exemplary embodiment of the present inventive concept, an apparatus for providing a user interface may include a touch screen displaying one or more objects and detecting an approach or a touch of an input by a sensor. A controller is configured to determine the input approaching the touch screen as hovering on the touch screen and to provide a lighting effect on the touch screen based on a position of the hovering input.
The controller may provide the lighting effect having a semi-transparent circular shape at a specific region on the touch screen.
When the position of the hovering input moves, the controller may provide the lighting effect at a moved region of the touch screen.
The controller may change an area of the lighting effect according to a distance between the hovering input and the touch screen.
The controller may change the area of the lighting effect to be inversely proportional to the distance between the hovering input and the touch screen.
The controller may change an area of the one or more displayed objects according to a distance between the hovering input and the touch screen when the hovering input interacts with the one or more displayed objects.
The controller may change the area of the one or more displayed objects to be inversely proportional to the distance between the hovering input and the touch screen.
According to another embodiment of the present inventive concept, a method for providing a user interface may include displaying the user interface including one or more objects on a touch screen. An input, which approaches to the touch screen, is determined as hovering on the touch screen. A lighting effect is provided at a specific region of the touch screen based on a position of the hovering input.
The lighting effect may have a semi-transparent circular shape.
The step of providing the lighting effect may include providing the lighting effect at a moving region according to a moving position of the hovering input.
The step of providing the lighting effect may include changing an area of the lighting effect according to a distance between the hovering input and the touch screen.
The area of the lighting effect may change to be inversely proportional to the distance between the hovering input and the touch screen.
The step of providing the lighting effect may include determining whether the hovering input interacts with the one or more displayed objects. An area of the one or more displayed objects is changed according to the distance between the hovering input and the touch screen when the hovering input interacts with the one or more displayed objects.
The area of the one or more displayed objects may change to be inversely proportional to the distance between the hovering input and the touch screen.
According to another embodiment of the present inventive concept, a method for providing a user interface may include outputting display information of a terminal to a screen of a vehicle when mirroring of the terminal is requested.
