Exam Preparation: Self-assessment 3 - Multiple-Choice Questions
1. Which of the following are, according to Shneiderman, aspects which must be
characterised in order to recognise the diversity of users?
A. Usage profiles.
B. Task profiles.
C. Interaction styles.
D. Typical errors.
E. Language use.
Options:
1. A, B and C
2. C, D and E
3. A, C and E
4. All of the above.
5. B, C and E.
2. Shneiderman suggests ‘complete sequences’ as a technique which can reduce
errors by ensuring complete and correct actions. An example of a complete sequence
is:
1. When a user types a left parenthesis, the system displays a message
somewhere on the screen that the right parenthesis is outstanding. The message
disappears when the user types the right parenthesis.
2. Command completion, which will display complete alternatives as soon as the
user has typed the first few letters of a command.
3. When a user correctly matches a menu item and a button that performs the same
function.
4. Logging onto a network requires that the user perform a sequence of actions.
When the user does this for the first time, the system can store the information
and henceforth allow the user to trigger the sequence with a single action. The
user is then not required to memorise the complete sequence.
5. None of the above.
