## Background
CROSS-REFERENCE TO RELATED PATENT APPLICATION
This application claims priority from Korean Patent Application No. 10-2009-0101737, filed on Oct. 26, 2009, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.
BACKGROUND
1. Field
The present disclosure relates to a method and apparatus for providing a user interface (UI) animation, and more particularly, to a method and apparatus for translating between an animation, to which physical rules are applied (hereinafter, referred to as ‘physics animation’), and an animation, to which physical rules are not applied (hereinafter, referred to as ‘non-physics animation’), and/or simultaneously displaying both the physics animation and the non-physics animation.
2. Description of the Related Art
Various techniques have been developed to enhance user experience when users use an application. For example, one of the various techniques is to apply an animation to a user interface. In particular, various attempts have been made to apply physical rules to UI animations. In such animations, to which physical rules are applied, it is possible to realistically and naturally represent a UI, but it is difficult to sufficiently control a plurality of UI objects in order to represent a desired UI animation.
That is, it is very difficult to reflect the location or state of each of UI objects based on physical rules in order to represent a desired UI animation. Even if the location and/or state of each of the UI objects are reflected based on physical rules, computational complexity increases, thus degrading system performance. Thus, when a UI animation is considered in terms of efficiency and aspects of realistic and natural representation, the UI animation should be divided into physical elements and non-physical elements. A physical element may coexist with a non-physical element, and translating between a physical element and a non-physical element should be performed naturally, if needed.

DETAILED DESCRIPTION
Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings. Like reference numerals denote like elements throughout the drawings. In the drawings, the size of each element may be exaggerated for clarity. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.
FIG. 1 is a schematic diagram of a user interface (UI) animation providing apparatus 100 according to an exemplary embodiment. The UI animation providing apparatus 100 includes an animation translation unit 180, a physics animation controller 150, a non-physics animation controller 160, and a display unit 170.
The physics animation controller 150 extracts a plurality of pieces of UI information, which are needed to express a physics animation mode from among a plurality of UI modes, from a UI object. The pieces of UI information needed to express the physics animation mode include information about gravity, force, torque, angular velocity, linear velocity, friction, restitution, damping, inertia, impulse, and mass. The pieces of UI information influence the UI object and may be used to calculate the motion of the UI object or to calculate an interoperation of the UI object, such as a collision between the UI object and another UI object.
The non-physics animation controller 160 extracts a plurality of pieces of UI information, which are needed to express a non-physics animation mode from among the plurality of UI modes, from a UI object. Animation types of non-physics animation mode include a translation type, a rotation type, a scale type, an alpha variation type, and a shape modification type (shape modification).
For a natural translation between a physics animation and a non-physics animation, the animation translation unit 180 extracts translation UI information associated with a plurality of pieces of UI information, which are needed to express the animation in the physics animation mode and the non-physics animation mode, and reflects the translation UI information into the UI object.
Specifically, the animation translation unit 180 includes a determination unit 110, a UI information extraction unit 120, a UI information translation unit 130, and a storage unit 140.
The determination unit 110 determines a current UI mode from among the plurality of UI modes that include the physics animation mode and the non-physics animation mode, and determines an animation type of the current UI mode.
The UI information extraction unit 120 extracts current UI information of a UI object for expressing the animation type of the current UI mode.
The UI information translation unit 130 translates the current UI information to the translation UI information in order to translate the current UI mode to another animation mode.
The storage unit 140 stores the translation UI information of the UI object.
The display unit 170 displays at least one UI object. The display unit 170 may simultaneously display UI objects corresponding to the non-physics animation mode and UI objects corresponding to the physics animation mode.
According to an exemplary embodiment, for performing a translation between a physics animation and a non-physics animation, operating elements of the physics animation and the non-physics animation may be effectively matched with each other to realistically and naturally display a UI animation.
According to an exemplary embodiment, a physics animation and a non-physics animation may be simultaneously displayed, thereby achieving the advantages of both the non-physics animation, the UI objects that can be easily controlled, and the physics animation, which allows video to be realistically and naturally displayed.
FIG. 2 illustrates translating from a translation animation type to a physics animation according to an exemplary embodiment. In the case of the translation animation type, the UI animation providing apparatus 100 of FIG. 1 extracts information regarding a UI object displayed as the non-physics animation, e.g., a starting location and time when the UI object starts to move and a target location and time when the movement of the UI object ends. The UI animation providing apparatus 100 calculates the force, acceleration, linear velocity, and a motion vector of the UI object, based on the extracted information and applies physical rules to the UI object according to the calculation results, thereby enabling the non-physics animation to be naturally translated to the physics animation.
FIG. 3 illustrates translating from a rotation animation type to a physics animation according to an exemplary embodiment. In the case of the rotation animation type, the UI animation providing apparatus 100 of FIG. 1 extracts information regarding a UI object displayed as the non-physics animation, e.g., an angle of rotation per unit time, etc. The UI animation providing apparatus 100 calculates the torque, angular velocity, and a motion vector of the UI object based on the extracted information, and applies physical rules to the UI object according to the calculation results, thereby enabling the non-physics animation to be naturally translated to the physics animation.
FIG. 4 illustrates translating from a scale animation type to a physics animation according to an exemplary embodiment. In the case of the scale animation type, the UI animation providing apparatus 100 of FIG. 1 extracts information regarding a UI object displayed as the non-physics animation, e.g., a variation in the size of the UI object. The UI animation providing apparatus 100 calculates the mass of the UI object based on the extracted information, and applies physical rules to the UI object according to the calculation result, thereby enabling the non-physics animation to be naturally translated to the physics animation.
The motion and rotational movement of the UI object are influenced by the mass thereof. When the UI object collides with another UI object, the degree of impact and collision shape that influence the other UI object depend on the mass of the UI object. If, during a translation from the non-physics animation to the physics animation, a variation in the size of the UI object is reflected without reflecting the mass of the UI object, then the non-physics animation cannot be naturally translated to the physics animation. If not only the UI object's mass and variation in size but friction and inertia are also reflected, the non-physics animation may be more naturally translated to the physics animation.
FIG. 5 illustrates translating from an alpha variation animation type to a physics animation according to an exemplary embodiment. In the case of the alpha variation animation type, the UI animation providing apparatus 100 of FIG. 1 extracts information regarding a UI object displayed as the non-physics animation, e.g., transparency, location, and size thereof. The UI animation providing apparatus 100 calculates whether the UI object is visible, the location, mass, and collision shape of the UI object based on the extracted information, and applies physical rules to the UI object, thereby enabling the non-physics animation to be naturally translated to the physics animation.
If the UI object displayed as the non-physics animation is transparent, the UI object should not be displayed in the world of physics animation. If the displayed UI object is opaque, the UI object should be displayed in the world of physics animation.
In an exemplary embodiment, although not shown, the non-physics animation may be translated to a shape modification type physics animation, in which a plurality of UI objects are combined and displayed as one UI object. In the case of the shape modification type physics animation, the UI animation providing apparatus 100 combines a plurality of UI objects into one object, and applies physical rules to the combination result, thereby enabling the non-physics animation to be naturally translated to the physics animation.
FIG. 6 illustrates translating from an alpha variation animation type to a non-physics animation according to an exemplary embodiment. In the case of the alpha variation animation type, the UI animation providing apparatus 100 of FIG. 1 extracts information regarding a UI object displayed as the physics animation, e.g., whether the UI object is visible, and the location and mass of the UI object. The UI animation providing apparatus 100 calculates the transparency, location, and size of the UI object based on the extracted information, thereby enabling the physics animation to be naturally translated to the non-physics animation.
A UI object that is not displayed in the world of physics animation is processed to be transparent in the non-physics animation, and is thus not displayed on a screen. A UI object displayed in the world of physics animation is processed to be opaque in the non-physics animation, and is thus displayed on the screen.
FIG. 7 illustrates translating from a shape modification animation type to a non-physics animation according to an exemplary embodiment. In the case of the shape modification animation type, the UI animation providing apparatus 100 of FIG. 1 extracts information regarding a UI object displayed as the physics animation, e.g., the shape of the UI object and the intensity and direction of force applied to the UI object. The UI animation providing apparatus 100 extracts information regarding the UI object, e.g., the initial shape and location of the UI object when the UI object is motionless based on the extracted information, thereby enabling the physics animation to be naturally translated to the non-physics animation.
FIG. 8 illustrates translating from a broken shape modification animation type to a non-physics animation according to an exemplary embodiment. In the case of the broken shape modification animation type, if a UI object collides against another UI object or force is applied to the UI object, then the UI object is broken into several pieces, thereby translating the physics animation to the non-physics animation. The UI animation providing apparatus 100 of FIG. 1 extracts a UI object displayed as the physics animation, e.g., the shape of the UI object and the intensity and direction of force applied to the UI object. The UI animation providing apparatus 100 calculates the initial shape and location of the pieces of the broken UI object when the UI object is motionless based on the extracted information, thereby enabling the physics animation to be naturally translated to the non-physics animation.
