What is an iDevice?
Throughout this document, the term 'iDevice' is used to refer to a portable
Apple device with a touch screen. This includes the iPod Touch, iPhone, and
iPad product lines. When a specific device is mentioned, it is intentional.
For instance, all iDevices have wifi, but only the iPhone and
cellular-enabled iPad can access cellular networks. This is not an official
term, but rather one adopted by the author for the sake of clarity.
What is iOS?
iOS is basically the operating system of the iDevice family. It is what
runs the iDevice and the platform on which all apps run.
What is VoiceOver?
VoiceOver is the screen reader that comes on all modern iPhones, iPads, and
iPods. It allows blind and low-vision users of these devices to hear what is
on the screen, which makes it possible to do just about everything a sighted
user can do. VoiceOver is found on the following devices:
* iPod Touch (all versions from 3 to 6, excluding some iPod Touch
third generation models) *iPad (all models, including Minis)
* iPhone (all models from 4 to 6 Plus, excluding some 3GS models)
What is Zoom?
Zoom is a feature that enlarges the content displayed on an iDevice's
screen. It can do this across the whole screen, or only within a certain
area of the screen, and it offers additional viewing options. You can invert
colors, for instance, to make text easier to read.
What is a gesture?
When talking about using VoiceOver, you very often hear the term 'gesture'
used to describe an action to be taken. A gesture is simply a motion to be
performed with your fingers to tell VoiceOver to do something, in much the
same way a keystroke on a computer is used to tell the computer to do
something. Common gestures are 'swiping', 'tapping', or 'rotating' with one,
two, three, or four fingers (note that rotating is only ever done with two
fingers).
What is an app?
An app is a program written for the iDevice that will accomplish some tasks.
There are hundreds of thousands of apps for Apple devices, and they do
everything from GPS navigation (on supported devices) to web searching to
music creation and playback to wordprocessing and a great deal more.
What is Braille Screen Input?
Braille Screen Input, often shortened to BSI, is a system introduced in iOS8
that lets you type braille directly on your device's touch screen.
What does 'jailbreak' mean?
Normally, iDevices will only run the apps that Apple approves; any apps in
the App Store have been given the green light by Apple. While this makes
sure that apps are secure and do what they say they do, it also can limit a
lot of functionality, so apps may not be able to do certain things because
of these restrictions. When an iDevice is jailbroken, it means that a
modified copy of iOS is installed on the device which lets it accept apps
without official approval from Apple. Essentially, jailbreaking lets users
install apps which may be able to do more than official apps can. The
process is relatively straightforward, but it is strongly recommended that
you do not jailbreak your iDevice unless you know what you are doing and
feel sure that jailbreaking would be of use to you. There are many
explanations and arguments both for and against jailbreaking, and we suggest
that you do a good deal of research before deciding. Note that jailbreaking
will void any warranty you have on your product.
