Abstract

Disclosed is a method for controlling animation images in a hyper text document in accordance with the reader's selection of a marked up text in the document. Most hypertext technologies provide hyper-link to switch the displayed document but they don't present controlling multiple images in a hyper text document with reader's interaction.

A Method for Interactive Control of Animation Images in a Hyper Text
Document

   Disclosed is a method for controlling animation images in a
hyper text document in accordance with the reader's selection of a
marked up text in the document.  Most hypertext technologies provide
hyper-link to switch the displayed document but they don't present
controlling multiple images in a hyper text document with reader's
interaction.

   Our method defines an animation image as an aggregation of
sub-images separately from the hyper text document source file, and
enables the following animation controls by reader's selection of a
marked up text by giving only a target image ID and an animation
operation ID in the hyper text document source file.

   - Change the image data displayed as sub-images - Change
the position and size of sub-images - Change the display priority
among sub-images - Switch display/non-display of sub-images - Start
and stop motion of sub-images

   All the information required to control an animation image
is described in an image definition block.  The image definition
block defines states of sub-image arrangement and animating
operations to sub-images for an animation image.  To describe these,
it contains one or more image state definition blocks and one or more
animating operation definition blocks.  Each of the image definition
block, image state definition block and animating operation
definition block has its own ID to be referred from the hyper text
document source file or from the inside of the image definition
block, and is bounded by the start tag and the end tag for each
block, so each can contain text strings and other blocks in it.

   The image state definition block and animating operation
definition block can contain a block to specify the appearance of one
sub-image and how the animation is performed to it.  Hereafter, this
block is named "set_sub-image" block.  The set_sub-image block gives
(1) sub-image ID, (2) sub-image's appearance which is attributed by
image data source, position in the animation image, size, display
status (i.e., visible or invisible), and display priority among
sub-images, and (3) animating parameters like time interval for
animation and animation step count to specify how many times the
sub-image is redrawn.  The sub-image's appearance is given by a
value, a predefined string, or a time dependent formula, and when
it's given by a time dependent formula, the sub-image appearance on
the display will be changed with the specified time interval without
a reader's interaction.

   A image state definition block is referred from a animating
operation definition block as a pre-state to arrange sub-images to
given state and then the animating operations are performed to
sub-images.  An animating operation definition block can refer to
itself or other animating operation definition as a post-operation
to repeat or continue animating operation.

   According to the rule described above,...
