EXERCISE 1.10 [extra - not in book]
Is it important that system designer takes account of individual differences when creating an interactive system? Justify your answer.
answer available for tutors only
Yes - although there are generalisations that can be made about human capabilities and limitations, individuals also differ on long and short term factors and some that change over time. Long term factors include gender, learning style, intellect etc. Short term factors include stress, fatigue. Factors that change over time include age, which of course effects physical capabilities, possibly intellectual (eg memory). Ignoring these for a user group will cause problems.
