00:00:01,120 --> 00:00:04,360
How People with Disabilities Use Digital Technology.

00:00:05,000 --> 00:00:07,920
Visual Disabilities.

3
00:00:07,920 --> 00:00:10,320
Visual disabilities affect how people see,

4
00:00:10,680 --> 00:00:14,560
including partial vision
in one or both eyes, not seeing at all,

5
00:00:14,880 --> 00:00:18,880
or seeing in a range of different ways
including colors and brightness.

6
00:00:20,040 --> 00:00:22,280
People
who are blind use assistive technology

7
00:00:22,280 --> 00:00:25,040
on computers and mobile phones
called screen readers.

8
00:00:25,960 --> 00:00:28,040
These software tools
can read the information

9
00:00:28,040 --> 00:00:30,880
on the screen out loud,
or they can present it in Braille.

10
00:00:31,880 --> 00:00:35,520
Screen readers can process websites
and apps with correctly coded headings,

11
00:00:35,720 --> 00:00:39,600
lists, links, buttons,
and other structures much better.

12
00:00:40,120 --> 00:00:42,560
Bird migration is the regular seasonal movement, 
often north and south along a flyway,

13
00:00:42,560 --> 00:00:43,680
between breeding and wintering grounds.

14
00:00:43,680 --> 00:00:45,560
Many species of bird migrate. Migration carries high costs.

15
00:00:45,560 --> 00:00:48,400
(A map of the world, showing some example bird migration routes image)

16
00:00:48,400 --> 00:00:49,320
Websites and apps

17
00:00:49,320 --> 00:00:53,120
also need to work with a keyboard
and have text alternatives for images.

18
00:00:54,440 --> 00:00:56,800
However,
most people with visual disabilities

19
00:00:56,800 --> 00:00:59,280
are not blind
but have some form of low vision.

20
00:00:59,800 --> 00:01:02,040
This means that people can partially see,

21
00:01:02,040 --> 00:01:04,320
just not clearly,
or within the full range of vision.

22
00:01:04,960 --> 00:01:08,400
Some people with low vision
use screen magnification software

23
00:01:08,400 --> 00:01:11,880
as a digital magnifying glass
to enlarge everything on the screen.

24
00:01:12,720 --> 00:01:15,680
This includes images, text
and the mouse pointer.

25
00:01:16,600 --> 00:01:19,960
With this, people only see small
parts of the screen at a time,

26
00:01:20,400 --> 00:01:23,480
so they rely on visual cues
and consistent design in websites

27
00:01:23,480 --> 00:01:26,520
and apps to stay oriented
and navigate effectively.

28
00:01:27,880 --> 00:01:28,600
Others with low

29
00:01:28,600 --> 00:01:31,160
vision might not use
the same assistive technology.

30
00:01:31,760 --> 00:01:34,960
They might adjust properties in the web,
browser or operating system,

31
00:01:35,280 --> 00:01:38,640
such as increasing the default text size
to better see the text.

32
00:01:39,520 --> 00:01:42,840
Websites and apps that are programed
and designed to adapt to the properties

33
00:01:42,840 --> 00:01:47,280
set by the users, such as different text
sizes, font type and line spacing.

34
00:01:47,600 --> 00:01:51,600
Allow people to use the content without
the text overlapping, getting cropped

35
00:01:51,880 --> 00:01:54,760
or requiring them to scroll
both vertically and horizontally.

36
00:01:57,400 --> 00:02:01,080
People who cannot distinguish certain
colors are often called “color blind”.

37
00:02:01,880 --> 00:02:03,360
Websites and apps that avoid

38
00:02:03,360 --> 00:02:04,840
text with low contrast,

39
00:02:04,920 --> 00:02:06,360
are easier to use.

40
00:02:06,800 --> 00:02:10,320
It’s also important that websites and apps
don’t use only color

41
00:02:10,320 --> 00:02:13,920
to communicate information,
but do use text and symbols in addition

42
00:02:13,920 --> 00:02:17,920
to color, such as an asterisk
to indicate required input fields.

43
00:02:18,760 --> 00:02:20,760
Some people are sensitive to bright light,

44
00:02:20,760 --> 00:02:24,440
so it's important that websites and apps
can adapt to the color schemes

45
00:02:24,440 --> 00:02:27,160
that people set in their browsers
and operating systems.

46
00:02:30,280 --> 00:02:33,880
You can make technology accessible to me.

47
00:02:35,200 --> 00:02:38,320
Accessibility: It's about people.
