COMP 20143: Human Computer Interaction

_____ ________ ___________ is becoming ever more important in interactive software. Such software has long been evaluated in terms of the availability and breadth of its functions and its algorithmic efficiency.

_______________ is a concept to be distinguished from another similar term, interface.

The term ____ __________ means that the resulting interfaces are easy to use, efficient for the task, ensure safety, and lead to a correct completion of the task.

In this context, the concept of user experience (UX) has lately become a ________.

This overall concept was well captured by the phrase, “Know thy user,” coined by Hansen in ____.

A related notion to the user-centered design is the concept of “universal usability,” which roughly promotes “_______” interfaces that cater to a wide range of users.

The term ____ refers to the job to be accomplished by the user through the use of the interactive system.

The capacity of the human’s short-term memory (STM) is about 5–9 chunks of information (or items meaningful with respect to the task), famously known as the “_____ ______”

The final major HCI principle is to favor “natural” interaction and interfaces. ____________ refers to a trait that is reflective of various operations in our everyday life.

Perhaps a better approach is to model interaction “______________” to the real life counterpart, extracting the conceptual and abstract essence of the task.
