BACKGROUND OF THE INVENTION
Interactive displays are increasingly used in a wide variety of public places from museums to corporate lobbies. As display size and quality increases, they have begun to attract the attention of graphic artists as well as information engineers, and recent experimental visual artists routinely incorporate computers into installations and exhibits. Stacks of video displays at trade shows and in public lobbies compete for potential customers' attention, and the most crowded booths are often those with the most visually interesting and interactive displays.
The first public use of this invention is expected to be a on a CD-ROM and in a museum exhibition featuring the work of a leading visual artist.
BRIEF SUMMARY OF INVENTION
An “Interactive Image Tiler” is a method for viewing multiple images which are can be thought of as being piled up in a display space. One or more view screens each display some subset of the display space and hence some subset of the images. Associated with each image is a mapping function which either maps each point of a two dimensional display space or each point in every display screen to a point in the image.
A grid is placed over the display space, and each tile in the grid becomes a window onto one of the images, as the points within that tile are filled with the results of the mapping function for that image. As the user moves holds the cursor over the view screen and hence over one of the tiles, the images are cycled under the tile at a slow but steady rate as long as the cursor remains over that tile. If the cursor is then moved away from the tile, the tile remains as a window onto the selected image. In this way a view screen can be turned into mosaic of tiles showing different images.
Clicking on a tile starts a spreading process in which the tiles near or adjoining the clicked tile tend to adopt the image of the clicked tile, in some measure expanding the window onto the underlying image. With each iteration the window becomes bigger until eventually, left unchecked, the image might take over the entire display space. As an alternative to clicking, the operator can press a button (keyboard key) which causes the tile under the cursor to immediately jump to the image linked to that button/key and then begin the same spreading process which would have taken place had the operator clicked on that tile with the new image. After having clicked on one tile, the operator can then move the cursor and click or key on another, starting another expansion which then competes with the first for display space real estate.
There are no restrictions on the nature of the images displayed. They can be movies and can be in motion provided their associated functions can map each point in the display space or each point on every view screen to a point in the image at all times. The images can contain buttons or other interactive elements and can react to rollovers which are too short in duration to cause any cycling.
In group settings such as a museum, multiple operators share the same underlying display space, but each operator has a separate input device. This allows an operator to click on a tile to initiate a spreading process which then interacts with spreading processes initiated by other operators.
