• the movements of the image during an animation sequence may be based on spring motion.
• the spring motion may be defined based on Hooke's law of elasticity, which, in mechanics and physics, states that the extension of a spring is in direct proportion with the load applied to it.
• the movements of the image during an animation sequence may simulate the effect of attaching the image (e.g., the center of the image) to one end of an imaginary spring, while the other end of the spring is attached to a position on the screen where the image should be displayed (e.g., in the display mode to which the image is transitioned).
• the image may be displaced from its destination position on the screen (e.g., receding backward, advancing forward, or panning around), Nevertheless, the image is tethered to its original position and state by the imaginary spring.
• the movements of the linage during an animation sequence may have a bouncing visual quality
• the movements of an image in an animation sequence (e.g., the speed at which the image changes its size or recedes backward or advances forward, the smallest or largest size of the image used in the animation sequence) during a mode transition may be determined based on the velocity or acceleration of a user's finger when making the touch gesture that causes the image io transition between two display- modes. For example, suppose that the user makes a swipe gesture by sliding a finger vertically (e.g., up and down) across the touchscreen of an electronic device. With some implementations, the velocity or acceleration of the user's finger moving vertically across the touchscreen may be recorded or determined.
• the velocity or acceleration of the user's finger moving vertically across the touchscreen is the velocity or acceleration in the "y” direction.
• This velocity or acceleration in the "y” direction may be translated into corresponding velocity or acceleration in the "z” direction for determining how fast or how far back the image should recede during the animation sequence. Since the image recedes backward and advances forward with respect to the screen, the image moves in the "z” direction.
• the user's finger's movements in the "y” direction on the touchscreen may control the image's movements in the "z” direction during the animation sequence. For example, if the user makes a faster swipe gesture, the image recedes backward faster and farther. Conversely, if the user makes a slower swipe gesture, the image recedes backward slower and closer.
• the velocity of the swiping gesture may he normalized (e.g., for scale and size) by dividing the velocity by a normalization factor.
• the normalization factor is itself a function of the velocity, "v”.
• the normalization factor is defined in terms of the velocity, "v”, as:
• the normalization factor is a linear function from 170 to 220, The velocity is thus normalized by dividing the velocity by the appropriate normalization factor for the range to which the velocity belongs.
