PCs are powerful general-purpose computing devices that many individuals rely on for accessing
information, connecting with friends, pursuing education, conducting research, and completing
work tasks.
This reliance extends to individuals with vision, hearing, cognitive, or mobility impairments,
as well as to
those whose abilities may decline due to illness or aging.
This chapter explores the accessibility features available on your Lenovo PC, including both
hardware
components and those offered by the pre-installed operating system. By gaining a comprehensive
understanding of the available accessibility features and how to activate and configure them,
you can
enhance your PC's usability for individuals with disabilities.
Accessibility features of the PC hardware
Lenovo PCs are designed with accessibility in mind. Throughout the design process, special
considerations
are prioritized for individuals with disabilities and best industry practices are implemented in
hardware
design.
USB connectors for connecting assistive technology devices
Several types of assistive technology devices are available on the market that can be connected
to a PC to
enhance its accessibility. For example, a refreshable braille display is an assistive technology
device that
enables individuals who are both deaf and blind to use a PC. When connected to a PC, a
refreshable braille
display can work in conjunction with a compatible screen reader to provide tactile output in
braille
characters. Blind individuals who have been trained to read braille can run their fingers over
the display to
comprehend the information presented on the PC.
Many assistive technology devices utilize USB technology for connectivity. Most Lenovo PCs are
equipped
with at least one USB connector that adheres to the relevant USB specifications and is backward
compatible. A Lenovo PC may feature a USB Standard-A connector, a USB Type-C connector, or both.
If the
plug type of the assistive technology device does not match the USB connector on your PC, you
can easily
purchase and use a USB adapter to resolve the issue.
Keyboard accessibility
The keyboard serves as the primary input device for many PC users. Lenovo keyboards, whether
integrated
or supplied separately with the PC, are designed and manufactured with accessibility in mind.
This section
highlights the accessibility features of Lenovo keyboards that benefit all users, including
those with
disabilities.
keyboard layout
The alphabetic keys on a Lenovo keyboard are arranged in a QWERTY layout, which is standard for
input
devices featuring alphabetic keys. The F and J keys have bumps that make them tactilely
distinguishable
from other keys. This feature serves as an orientation aid for skilled typists, allowing them to
rest their index
fingers without looking at the keys. Some Lenovo keyboards include a separate numeric keypad.
The
numeric keys are organized in four rows and three columns, arranging in ascending order from
left to right
and bottom to top. Additionally, the 5 key features a bump to make it tactilely distinguishable
Standard modifier keys
Lenovo keyboards are equipped with standard modifier keys for PCs, including:
- the alt key
- the ctrl key
- the shift key
- the Windows logo key
These keys are extensively used as the modifier key for shortcuts by the operating system and
other
applications.
The tab key
The tab key is located in the leftmost column of the keyboard. For operating systems,
applications, and web
documents that are designed with accessibility in mind, users can press the tab key and alt +
tab (in reverse
order) to cycle through the interactive elements.
Hotkeys
Many Lenovo keyboards feature hotkeys in the top row, offering convenient access to frequently
