Optimizing Block and Flow Scans
Scan Optimization only works in Block Scan Mode and Flow Scan Mode.
To optimize block and flow scans, Choose
Menu
>
Settings
>
Input >
Scanning
>
Patterns
. Then turn on
Scan Optimization
.
When Scan Optimization is turned on, blocks or flows are scanned in the
most efficient way on each page.
If you turn Scan Optimization off, blocks or flows will be scanned the
same way on all pages.
With Scan Optimization turned on:
Flow finds the lowest average # of
scanning steps for every button on a page. Visualize the page layout in
one straight line. For example, if you break the buttons on a page into 6
equal groups, it takes 5 scanning steps just to get to the 6th group. Flow
adjusts the groups so the initial one is larger, spreading the groups over
the page to average the number of scanning steps over the entire page
more equally.
With Scan Optimization turned off:
Flow scans equal groups of buttons
on every page. Visualize the page layout in one straight line. For
example, if you break the buttons on a page into equal groups, the
same number of buttons will be scanned in each group.
