2. • Usability is a quality attribute that assesses how easy
user interfaces are to use
• It also refers to methods for improving ease-of-use during
the design process

3. 1. Learnability:- How easy is it for users to accomplish
basic tasks the first time they encounter the design?
2. Efficiency:- Once users have learned the design, how
quickly can they perform tasks?
3. Memorability:- When users return to the design after a
period of not using it, how easily can they reestablish
proficiency?
4. Errors:- How many errors do users make, how severe
are these errors, and how easily can they recover from
the errors?
5. Satisfaction:- How pleasant is it to use the design?

4. DEFNITIONS
• Simply, Universal usability means :- usable to all.
• Universal usability refers to the design of information
and communications products and services that are
usable for every citizen.
• Enabling all citizens to succeed using communication
and information technology in their tasks.
• The design of products and environments to be usable
by all people, to the greatest extent possible, without the
need for adaptation or specialized design.

5. • Practical definition of universal usability – "having more
than 90% of all households as successful users of
information and communications services at least once a
week."

6. 1. Supporting a broad range of hardware, software, and
network access.
2. Accommodating individual differences among users,
such as age, gender, disabilities, literacy, culture,
income, and so forth.
3. Bridging the knowledge gap between what users know
and what they need to know about a specific system.

7. • Design simply: - Design simple sites, emphasizing
important elements and using simple structures and
clean, standards-based markup.
• Build well:- Take full advantage of these inherent
properties, such as fallbacks, flexibility, and user control,
to construct universally usable Web sites.
• Favor HTML over other formats:- HTML is the best format
for universal usability. Provide documents in nonstandard
formats, such as PDF and Flash, only as an alternative to
accessible html.

8. • The goal of universal usability is to enable the widest
possible range of users to benefit from information and
communications services. This goal is stronger than
merely providing access, which focuses on technology
availability and is often tied to access for users with
disabilities.
• Universal usability implies that diverse users with varying
language skills, knowledge levels, motivation, and
computer hardware/software can successfully apply
technology to get what they need in life.

9. • Universal usability uses Multilayer design

10. • User Experience is described as "A
person’s perceptions and responses that result from
the use and/or anticipated use of a product, system or
service".

11. • Accessibility is concerned primarily with making the
content and functionality of web sites accessible- within
reach -to all users.
• Accessibility’ defines a set of technical requirements that
could be met and yet the result may not be universally
usable.
• Universal usability goes one step further, striving to make
the content and functionality accessible and usable by all.
• It specifies not just the attributes of the technology but the
experience of the users

12. • FLEXIBILITY
considering universal usability, we need to anticipate
diversity and build flexible pages that adapt gracefully to a
wide variety of displays and user needs.
• USER CONTROL
Flexibility paired with user control allows users to take
control of their web experience and shape it into a form that
works within their use context.

13. • KEYBOARD FUNCTIONALITY
Make actionable elements workable via the keyboard to
ensure that the interactivity of the web is accessible to the
broadest spectrum of users.
• TEXT EQUIVALENTS
Text equivalents allow universal usability to exist in a
media-rich environment by carrying information to users
who cannot access information in a given format.

14. • Government of India official portal with universal usability
features

15. Site with Hindi language option for the users who don’t know E

16. Site with high contrast colour option for visually challenged users

17. “There are many people at
work on universal
usability. It’s gratifying to
see that when we speak
about it, students,
researchers,
professionals, and policy
makers listen. And along
with attention comes
results”
