6   Magnifying with ZOOMS

This chapter describes the Nuance ZOOMS magnification component, which you
can obtain in a standalone configuration and also in combination with the
Nuance TALKS software. Magnification is available with or without speech
output; if your version supports only magnification or only speech output,
the features that correspond to the missing component are not available.

Please note that ZOOMS is currently not support on Symbian^3 phones.

6.1  Getting started with magnification

The magnification feature acts like a magnifying glass, enlarging screen
elements to enable you to view them more easily. You can move the magnifier
around the screen to access different areas. The portion of the screen that
is enlarged depends on your settings and the actions that you are
performing. For example, ZOOMS can use the entire screen area to magnify
one element (referred to here as full-screen magnification) or divide the
screen into several areas to display several elements simultaneously
(referred to as distributed views). When you scroll through a menu or a
list of options, ZOOMS magnifies each item along with some of the
surrounding area.

Using key commands, you can easily move the magnifier to elements such as
the title of the window, the soft keys, or the display of the battery
level--and at the same time, you can hear TALKS read out the information
that you are viewing. In addition, when the magnifier is on an object that
does not fit entirely onto the screen, such as a menu item, the smart
scrolling feature automatically begins to scroll through the text after a
brief delay.

If you prefer gray text to colored text, you have an option to convert the
text to shades of gray and to invert the colors so that the display looks
like a film negative.

To turn on magnification:

ù Press  [TALKS], [ Long  Call].

Or

ù In the  TALKS&ZOOMS Settings dialog box, on the  Magnification tab, set
Magnification to On.

The magnification feature is activated and, using the area of the entire
screen, displays a magnified version of one portion of the screen (to find
out how to change this display mode, see section ).

6.2 Navigating with the magnifier

Most of the navigation keys described in this section correspond to the
keys that activate TALKS speech output for certain parts of the screen. If
TALKS is active along with ZOOMS, the key sequences produce speech and
magnify the screen at the same time.

To scroll vertically or horizontally:

ù Press and hold  [Up],  [Down],  [Left], or  [Right], depending on the
direction in which you want to scroll. (To stop the scrolling, release the
key.)

Or

ù On a device with touch screen, hold your finger down for about half a
second, and then start moving to "drag around" the magnified part of the
screen under the "magnifying glass".

Note: To navigate through menus one by one, press and release  [Up] or
[Down] just as you do when magnification is not active.

To magnify one of the soft keys:

ù Press  [TALKS], [ Key 1]. Press this key sequence again to move to the
other soft key.

To magnify the status indicators:

ù Press  [TALKS], [ Key 2] once to view the battery indicator, in the upper
right corner.

ù Press  [TALKS], [ Key 2] twice rapidly to view the network indicator, in
the upper left corner.

To magnify items in the upper part of the screen (such as tabs, the case
indicator, or application icons):

ù Press  [TALKS], [ Long Key 2]

Note: This key sequence usually applies to functions that are relevant to
the active application rather than the entire phone. Please note that it is
not available on devices with a touch screen.

To magnify the title of the window:

ù Press  [TALKS], [ Select].

To magnify the line of text where the cursor is:

ù Press  [TALKS], [ Left].

To magnify the currently selected object:

ù Press  [TALKS], [ Up].

6.3 Magnification settings

This section describes the various options that you can select to customize
the ZOOMS magnification feature to your needs. To change any of these
settings, open the  TALKS&ZOOMS Settings dialog box and select the
Magnification tab.

6.3.1 Screen mode

The  Screen mode setting determines how the screen is divided when
magnification is active. You have two options:

ù  Full screen: ZOOMS uses the entire screen area to display a magnified
version of one subsection of the active window.

ù  Distributed views: The screen is divided into four parts: a large
section at the center; a smaller section at the top, showing the title of
the window at twice its normal size; and two small sections at the lower
end of the screen, which show the soft keys at twice their normal size. The
 Distributed views option is intended mainly for use at low zoom factors
(see section ), and it keeps important information visible just as the
un-magnified screen would.

To switch the Screen mode setting:

ù Press  [TALKS], [ *].

6.3.2 Zoom factor

The zoom factor is a measure of magnification--for example, a zoom factor
of 200% means that the display is shown at twice its normal size.

In addition to various degrees of magnification, the  Zoom factor parameter
provides an option called  Auto-fit focus. If you select this option, the
zoom factor changes dynamically to make the text always appear at a certain
height regardless of its size on the original display. The height of the
text depends on what you select for the  Auto-fit focus parameter (see
section ).

If you do not want the screen to be magnified but do want to use other
Magnification tab settings, such as  Inverted Colors, set  Zoom factor to
100%.

To change the degree of magnification:

ù Press  [TALKS], [7] to zoom out, or  [TALKS], [8] to zoom in.

Note: When  Zoom factor is set to  Auto-fit focus, these key sequences
change the number of lines that are visible at one time. See section .

Or

ù On the  Magnification tab, select  Zoom factor, and then select either a
percentage of magnification or  Auto-fit focus.

6.3.3  Auto-fit focus

The  Auto-fit focus setting controls approximately how many lines of text
are visible at one time. The fewer the lines, the larger the text is. For
example, if you select the  1 text line option, the text is enlarged to fit
the height of the screen. If you select  5 text lines, the text is enlarged
to a much smaller degree. Auto-fit focus is applicable only if you have
already set the  Zoom factor parameter to  Auto-fit focus.

To change the number of lines visible on the screen at one time:

ù Press  [TALKS], [7] to view more lines on the screen, or  [TALKS], [8] to
view fewer lines.

Note: This key sequence changes the number of visible lines only if the
Zoom factor parameter is set to  Auto-fit focus.

Or

ù On the  Magnification tab, select  Auto-fit focus, and then select a
number of lines.

6.3.4 Color processing

Using the  Color processing setting, you can customize the color display to
make the text more readable for you. You have the following options:

ù  None: Retains the original screen colors

ù  Black/white: Replaces the colors with a high-contrast black-and-white
display

ù  Greyscale: Replaces the colors with shades of gray

6.3.5 Invert colors

Use the  Invert colors setting to reverse the colors on the screen and
create a negative of the image to improve readability. For example, when
you set  Invert colors to  Yes, black areas become white, and white areas
become black.

To invert the colors or reset them to the original colors:

ù Press  [TALKS], [ Long *].

6.3.6 Scrolling speed

By default, the magnifier scrolls across the screen automatically. The
Scrolling speed setting controls the speed of this automatic scrolling (see
section ) as well as the speed at which you can scroll manually with the
navigation keys. You can select a value from 1 (slowest) through 6
(fastest).

6.3.7 Auto-scroll delay

As described in section , the magnifier scrolls across the screen
automatically. However ZOOMS waits for a short period of time after the
last change on the screen before the automatic scrolling begins. Use the
Auto-scroll delay setting to control how long ZOOMS should wait before
beginning the automatic scrolling. You can select a value from 0.25 second
to 4 seconds. If you don't want the magnifier to scroll automatically,
select  No. You can scroll manually with the navigation keys.

The speed at which the magnifier scrolls depends on the  Scrolling speed
setting (see section ).
