One Size Fits All
“… the human interface of some software applications gives the impression that the designer’s model of the user was a 25-year-old male with a doctorate in computer science who is besotted with technology and is more interested in playing with a computer than in completing useful job of work!”

Persona with Important Personal Factors Listed
• Rose is an 83 year old great grandmother. Although fiercely independent, she struggles with everyday tasks like shopping, cooking and housework. Carol and David need to come round most days to help.
• She still greatly enjoys an active social life - including her regular bridge and quiz night every week and going out for meals with the whole family.
• Unlike David, Rose has come to accept her hearing aid as a necessity. She has worn reading glasses for many years and always carries them with her.
How to address needs of everyone?
The answer is − Universal Design
