Figure 8: The Scanning Dialog
The Audio Feedback drop-down menu allows you to set your Palmtop device to provide you with either a
click or a spoken description for each group as it is highlighted.
There are also options that allow you to have the system unselect a group after a given number of scanning
cycles. This feature is often set to one or two cycles so that an incorrect group selection will be unselected
automatically in a reasonable amount of time. Likewise, the system can be set to pause scanning after
several cycles if no action is made. This feature allows you to eliminate the visual and/or audio distraction of
the scanning process when the system is not in use.
See section 4.7 for additional details on the scanning options.
3.17. Help for Users Who Have Trouble Selecting Buttons or
Keys
Some people who use the Palmtop device have trouble reliably selecting individual buttons or keys due to
tremors or lack of fine movement control. To assist these individuals, several different methods of "filtering"
user input are available, to make selections more reliable. The
StickyKeys feature allows these users to
enter shifted characters by selecting the Shift key and then the character (rather than selecting them
simultaneously). The
FilterKeys options help prevent these users from accidentally selecting the same button
twice (due to jitters or from holding the button down too long). They also help to prevent selections caused
by accidentally brushing the screen or keyboard while trying to select a button. To set up the Palmtop input
filtering methods, select
Tools > Options in the menu bar, and then press the Input Filtering Configure
button. These features are described in detail in section 4.5.
Because the Palmtop is a relatively small device, individual onscreen buttons can be difficult to select or hard
to see - a user may end up selecting more than one button or accidentally selecting the wrong button. The
magnification feature makes it easier to see and select buttons. When this feature is enabled, the area
around the place where the user selects the screen will appear magnified. The user can then select the
desired button from this magnified region, or select outside of the region if they do not want to select any of
the magnified buttons. The size and magnification of the region can be tailored to fit the needs of the user. To
enable the magnification feature, select
View > Zoom Mode in the menu bar or select Tools > Options and
select the Enabled check box under Magnification . Section 4.4.3 describes how to use the dialog to
configure magnification.
