Computers and older adults• Global aging population changed the

landscape of information technology industry– Existing older adults increasingly expose to IT

• Older adults are now the fastest growing population of computer buyers and Internet users 1, 2

– As we grow up, future older adults will become IT savvy

Motivations• Older adults have different needs and

concerns• Current interfaces which are mostly

designed for younger users and are too complex for older adults 1

• Majority of the functionalities are not needed or used

Motivation• Question:

• Not much has been discussed about the use of specific applications for activities that they do 1

What essential applications and

functionalities should it support?

We are interested to find out the essential needs of older adults in computer usage, and how such needs are reflected in the type of computing activities carried out as well as the most common computer applications being used.

Interview

Participants• 8 computer literate participants (5 male, 3

female, age range 51-73, M: 64.5, SD: 7.89)

Format• Semi-structured interview• Questions covered:

– Experience with learning and using of computers

– Type of computing activities and motivations such activities

Take-away & Implications• The essential interface for older adults should

probably only include the above functionalities• Make the interface consistent

– Changes made to interfaces should be handled carefully as older adults may not adapt effectively
