This document discusses user interface design considerations for people with special needs. It outlines design principles for elders, children, and those with visual, cognitive, learning, and physical disabilities. Key recommendations include using simple and clear navigation, descriptive text, reduced clutter and text, increased font and icon sizes, color blindness-friendly color combinations, screen reader compatibility, and alternative input methods like eye tracking, gestures, head tracking, and brain interfaces. The goal is to design inclusive and accessible interfaces through principles of universal design.

1. User Interface Design for
People with Special Needs

2. Human Computer Interaction
HCI researches the design and use of computer technology, focused on the interfaces between
people (users) and computers.

3. Design for all
Design for all is an umbrella term for a wide range of design approaches, methods, techniques
and tools to help address this huge diversity of needs and requirements in the design of
interactive technologies.

4. Designing User Interface for Elder Users
Elders issues User interface design solutions:
issues solutions
Lack of computer background · Putting a basic users’ guide and help in the
software
· Reduction of terminology
Cognitive changes · Reduced clutter on the screen
· Clear and simple navigation paths
Memorizing difficulties · Using similar functions for doing different jobs
· Putting descriptive texts and guidelines for tools

5. Designing User Interface for Children
Children do not like to read text, they prefer animation and sound, they also like to try many
options.
for this reason it is recommended when designing
children’s user interface:
 reduce the amount of text, replacing it with a simple
picture, icon or voice.
 reduce the number of components and increase their
size.

6. User Interface for People with Visual
Impairments
Common visual impairments can include:
 Color blindness
 Low Vision
 Blindness

Impairments
Color Blindness
 using a combination of colors that is
distinguishable for these people
 Use both colors and symbols
 should not use similar colors next to one
another.

8. User Interface for People with Visual
Impairments
Low Vision & Blindness
 creating software in the way that could be read easily by screen reader software
 putting the ability of zoom in our software
 Putting customization abilities in software for tailoring font size and color.
 putting speech recognition for interacting with software
 haptics interface

9. User Interface for Solving Cognitive and
Learning Disability Problems
people with CLDs often exhibit deficiencies in attention, memory, perception and problem-
solving, which affect the manner in which they interact with computers.

10. User Interface for Solving Cognitive and
Learning Disability Problems
Some research has been done about designing interfaces for people with dyslexia
Top tips for designing web pages and sites for users with dyslexia:
 use the background color suggested by dyslexia experts.
 avoid cramping material and using long, dense paragraphs: space it out
 use graphic, images, photos to increase their understanding.

11. User Interface for Solving Cognitive and
Learning Disability Problems
There have also been many studies about interface design for people with autism
Top tips for designing for users with autism:
 Use contrast between font and background.
 Use soft, mild colors.
 Make sure text box is clearly separated from the rest.
 Present text in a single column.
 Use simple graphics.
 Use clear, sans-serif fonts.

disabled
Solving the usability and accessibility problems of mobility impairment users require special
hardware

disabled
Eye Tracking
an eye tracking device recording their eye
movements and a computer program analyzing
and interpreting their eye movements

disabled
Gestures & Head Tracking
there are various approaches to gesture
recognition, employing a variety of imaging and
tracking devices or gadgets.
Wearable devices are an unobtrusive solution to
gesture-based interaction, functioning not only as
an output but also as an input device.

15. Designing User Interface for people with physical
disabled
Brain Interfaces
This interfaces allow a user to send messages
voluntarily without sending them through the
brain’s normal output pathways such as speech,
gestures or other motor functions, but only using
bio-signals from the brain.
