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.
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:
· Press [TALKS], [ Long Call].
Or
· 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 ).
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:
· 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
· 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:
· Press [TALKS], [ Key 1]. Press this key sequence again to move to the other soft key.
To magnify the status indicators:
· Press [TALKS], [ Key 2] once to view the battery indicator, in the upper
right corner.
· 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):
· 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:
· Press [TALKS], [ Select].
To magnify the line of text where the cursor is:
· Press [TALKS], [ Left].
To magnify the currently selected object:
· Press [TALKS], [ Up].
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.
The Screen mode setting determines how the screen is divided when magnification is active. You have two options:
· Full screen: ZOOMS uses the entire screen area to display a magnified version
of one subsection of the active window.
· 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:
· 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:
· 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
· 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:
· 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
· On the Magnification tab, select Auto-fit focus, and then select a number of lines.
Using the Color processing setting, you can customize the color display to make the text more readable for you. You have the following options:
· None: Retains the original screen colors
· Black/white: Replaces the colors with a high-contrast black-and-white display
· 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:
· 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).
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 ).
