Chapt 3 : Interaction

What is the primary purpose of interaction models in HCI?

• To design graphical interfaces

• To improve system speed

• To describe the communication between users and systems

• To replace human interaction

Which of the following is NOT a key component of Norman's interaction model?

• Formulating intention

• Debugging system errors

• Executing action

• Evaluating system rate

In the Execution-Evaluation Loop, what does the user do after perceiving the system state?

• Interprets the system state

• Specifies actions at the interface

• Executes an action

• Establishes a new goal

Abowd & Beale's interaction framework primarily deals with:

• Ergonomics of hardware devices

• Translating between different system languages

• Comparing system performance

• Identifying all components of interaction

Which of the following best defines ergonomics in HCI?

• The study of computer networking

• The study of how users physically interact with systems

• The speed of system response

• The efficiency of programming languages

Which is NOT an example of an ergonomic consideration in interface design?

• Screen Brightness

• Keyboard Size

• Font style preference

• System processing speed

Which interaction style requires users to type commands directly into a system?

• WIMP

• Command Line Interface

• Menus

• Query Interface

In WIMP interfaces, what does "P" stand for?

• Pointer

• Processing

• Page Layout

• Physical Design

Which interaction style relies on users selecting options from displayed choices?

• Command Line Interface

• Menus

• Direct Programming

• None of the Above

Which of the following is a major issue with natural language interfaces?
