ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to user interactive computer supported display technology and more particularly to such user interactive systems and methods which are user friendly and provide easy to use interactive user interfaces.
2. Description of the Related Art
The 1990's decade has been marked by a technological revolution driven by the convergence of the data processing industry with the consumer electronics industry. This advance has been even further accelerated by the extensive consumer and business involvement in the internet over the past few years. As a result of these changes, it seems as if virtually all aspects of human endeavor in the industrialized world requires the distribution of information through interactive computer display interfaces. Information for reporting, marketing, technology and educational purposes, which in the past was permitted days and even months for distribution, are now customarily required to be “on-line” in a matter of hours and even minutes. The electronic documents through which such information is distributed is made up of a variety of information types, e.g. text, graphics, photographs and even more complex image types. Because of the limited time factors involved in the creation, updating and reading of computer displayed documents, there is a need for a method and system for navigating through these documents which are fast and relatively effective.
For example, the conventional method of allowing a user to view very large sets of data in tree, table or list formats is to display every item in the list. The user is then provided with a scroll bar that moves a small window in a vertical direction. At any time, however, only a very small segment of the tree or list is displayed. Thus, in order for a user to view an entire structure of a large data set, the user has to scroll through the entire list of data. Even then, however, the user may not be able to visualize the whole structure of the data set. A need, then, exists for a method and system to provide a user the ability to potentially view an entire structure of a large list of data on a view screen.
SUMMARY OF THE INVENTION
The need is addressed by the present invention. The invention provides a compress function which presents an image of a list of items in a vertically compact form in order to reveal a global structure of the data making up the list. To expand and view detailed information of the data, the original image is reconstituted. The invention makes use of a bitmap of the image of the items. Rows of pixels that should be used in the image are indicated as displayable in the bitmap; those that should not be used are indicated as non-displayable. Thus reconstituting the image merely entails changing the status of rows from non-displayable to displayable.
