embodiment, the entire navigation path, including the keypress event, is sent with each keypress. When the navigation
path is sent with each keypress event, the SSS is able to
identify the requested matrix layer rapidly on the fly.
Subsequently, at functional block 612, the client node
receives the updated matrix layer corresponding to the keypress event. That matrix layer is loaded to the memory at
functional block 614 and the cache is time-stamped at functional block 616. At functional block 618, new ads may be
received from the SSS. Notably, the receipt of the ads is
asynchronous with the matrix layer receipt and may occur at
any time without being prompted by a keypress event. At
functional block 620, the incoming matrix layer is rendered to
a temporary buffer by using a double-buffering technique.
The actual rendering is transparent to the user. At functional
block 622, the status bar for the load is updated to indicate the
percent complete of the matrix layer rendering. At functional
block 624, a determination is made if the rendering is complete. If it is not, the buffer continues to render and the status
bar continues to update. By regularly updating the status bar,
the user is not left wondering if the device is working. This is
expected to limit the frustration experienced by many new
users during the wait while matrix layers are rendered. If the
rendering is complete, the temporary buffer is swapped with
the frame buffer and the new matrix layer is displayed at
functional block 626. Then at functional block 628, the history of the navigation path is updated to reflect the new matrix
layer. The system then returns to await a next keypress to
indicate further navigation. By iteratively pressing appropriate keys, a user may navigate to any desired depth up to a
maximum depth along any navigation path and obtain content
relevant to the path navigated. If instead, the matrix layer was
validly in the cache at decision block 608, the matrix layer is
rendered from the cache at functional block 630 and the
system awaits the next keypress.
"Maximum depth" as used herein applies on a cell by cell
basis for primary navigation options. A maximum depth is
reached for a cell in a navigation path when pressing a corresponding key will not take a user to a deeper matrix layer in
the matrix. While content, as distinguished from the matrix
layer and their cell headings, will be displayed once a maximum depth is reached, it is within the scope and contemplation of the invention to display some content in cells of an
intermediate matrix layer, i.e. one that is not at the maximum
depth.
"Primary navigation options" as used herein are those navigation options that necessarily change between successive
matrix layers, changing from general to more specific with
increases in depth in the matrix.
FIG. 7 is a flow diagram of operation of the sister site server
of one embodiment of the invention. A determination is made
if the keypress event has been received at decision block 702.
If the keypress event has been received, a determination is
made if the matrix has reached maximum depth at decision
block 704. If the matrix has not reached the maximum depth,
a matrix layer corresponding to the keypress is sent at functional block 706. Such matrix layers may or may not include
content in cells with navigation choices. If the matrix has
reached maximum depth for that navigation path, a content
layer corresponding to the keypress event is sent to the client
node at functional block 708. A content layer may or may not
include matrix cells in addition to the content. New ads are
sent to the client node at functional block 710. The system
then awaits the next keypress event from a client node.
FIG. 8 is a diagram of the display of a graphical user
interface of one embodiment of the invention. The screen is
divided into a plurality of cells. In this embodiment, there are

fifteen cells that represent navigation options and one messaging cell for displaying messages from the server, the
progress or status bar, and a title block. The cells can further
be subdivided between the digit keys 1-9 keys which, in this
5 embodiment, represent the primary set of navigation options
and the keys designated by letters A-C which represent secondary navigation options and *, 0, and # keys that may be

will typically hold advertising, and selecting one of those
cells will generate a matrix layer with primary navigation
cells directed to that advertiser or the product line being
advertised. While the interface is designed to be fully acces15

The first advertisement 902 is highlighted. From this matrix

such that only four advertisements are displayed in ad cell
900. The no links/advertisements are highlighted. In FIG. 9c,
advertisement 902 is again highlighted. This may occur, for
example, by a user pressing a scroll key from FIG. 9b. In FIG.
9d, a user has pressed a scroll key several times from FIG. 9c.
30
Thus, advertisement 902 has scrolled out of view and advertisement 904 is highlighted. While in this example, ten advertisements were present, the number of links within such a cell
may be arbitrarily large. In the shown embodiment, scrolling
through the links in the focus cell and scaling the focus cell

Selecting 1 on the keypad when the matrix layer of 10b is

45 selecting an 8 on the keypad when 10c is displayed, the
system displays a Receivers matrix layer of FIG. 10d, which
breaks down receivers into price categories and also provides
the option of navigating, in this embodiment, into Consumer
Reports industry reports related to receivers. Notably, in FIG.
50 1 Od, the number of primary navigation options is reduced to
4. Thus, it is not necessary that all layers of the matrix have the
same number of cells, nor is it required that all cells have the
same size. A user can select Stereo Only by pressing 1 on the
keypad, which yields a stereo only matrix layer shown in FIG.

In one embodiment of the invention, the products are
ordered based on some ranking system, such as Consumer

the highest ranking of receivers in the selected category from
60 Consumer Reports. It is expected that for any particular product class, potential purchasers are likely to only be interested
in the top several products within that class, not for example,
