SPOT READING

 Once you have captured a document

(either at Working Range: Close-up or

Full Page), you will notice a rectangle

frame on the top left corner. This is

Prodigi’s locator. Move the locator by

slowly moving your finger on the

touchpad without lifting it (pan

gesture) to quickly reach a section of the

document you want to read:

Page 18

 Tap to enlarge the section delimited by

the locator:

 When a section of a document is

magnified, pan to reach other parts of

the document.

 Press Back to see the locator again.

This is a practical way to locate your

position on the document.

USING THE CAROUSEL MENU

Prodigi has 3 main applications – Magnifier,

Gallery, and Settings. They are presented

one by one in the carousel menu:

Page 19

To access the carousel menu from the

Magnifier:

 Press Back to close the Magnifier and

access the carousel menu.

 Prodigi will announce “Main Carousel”

followed by the currently selected

application. The currently selected

application is positioned in the center of

the screen:

 Swipe left or right in the carousel menu

to select an application.

 To launch a selected application, simply

tap.

 To cancel, press Back.

Page 20

VIEWING SAVED DOCUMENTS

The Gallery contains all the documents you

saved.

 Select and tap on the Gallery in the

carousel menu:

 Swipe left or right in the Gallery to flip

through your saved documents.

 The currently selected document is in

the center of the screen. Prodigi will

announce and indicate the first word

contained in the currently selected

document. If the document contains no

words, Prodigi will tag it as an image.

 To open a selected document, simply

tap.

 Move the locator to quickly reach a

section of the document you want to

magnify.

 Tap to see the section delimited by the

locator at your preferred zoom level.

Page 21

 You can toggle between color, positive,

negative, and Diamond Edge™ (if the

image contains text) contrasts, and

adjust the brightness in the same way

as with the Magnifier (see section

Magnifying (Standard interface) for more

information).

 Press Back to see the locator again.

 Press Back again to close a document

and return to the Gallery. Once you

close a document, Prodigi will

remember your position and apply it

automatically the next time you open the

document.

Notes: Prodigi will announce “Gallery empty”

if the Gallery contains no documents. The

Gallery cannot contain more than 100

documents. Once you pass this number, you

will be prompted to delete some documents

from the Gallery before saving new ones.

Page 22

To delete a document:

 In the Gallery, press and hold your

finger down on the image you want to

delete. You will be prompted ‘DELETE?’

and a red ‘X’ will appear. Tap to confirm,

or press Back to cancel.

CHAPTER 5: CHOOSING YOUR

CONTRAST

Prodigi allows you to view documents,

pictures and objects in 3 types of contrast:

color, positive or negative. For documents

that contain text, a 4th type of contrast can be

used: Diamond Edge™. Positive, negative,

and Diamond Edge™ contrasts are

enhanced; they are meant to enhance the

original color of a document or object to

facilitate your visual experience.

Page 23

Color contrast is useful if you want to view

documents, objects, and photographs in their

original color.

Positive contrast shows text and images in 2

colors according to your selected color

combination, the default combination being

Black on White. This is a practical way to

view text in the best color combination for

your vision.

Negative contrast shows text and images in

reversed contrast as compared to your

selected color combination. For example, if

your combination is Black on White, negative

contrast will show text and images in White

on Black. This is useful if you wish to reverse

the contrast of a text that contains different

contrasts.

Diamond Edge™ contrast combines the best

of both worlds; it shows Diamond Edge

Text™ in your selected color combination

and images in their original color. This allows

you to magnify text indefinitely without

compromising its quality in the best color

combination for your vision, while viewing

Page 24

images in their original color on the same

page.

To toggle between the different contrasts,

press and hold the Back button to access the

Settings, select Contrast, and tap to choose a

contrast. Press Back to return to your

document or object.

Prodigi’s Standard interface also allows you

to toggle between the different contrasts by

swiping on the right edge of the touchscreen:

Note: The contrast cannot be changed while

in Line or Column mode, or while viewing an

image at 1x (Read View or Gallery).

Page 25

CHAPTER 6: CHANGING YOUR

SETTINGS

The currently selected item is announced and

or down to move the rectangle and select an

item. The items will be read one at a time (by
