INTRODUCTION

Interaction refers to the process of communication that occurs between two entities at a specific time.  The entities could be humans and or machines.

HISTORY AND EVOLUTON

The Human-Computer Interaction (HCI) is a field of research involving the development, evaluation and implementation of an interactive computer system that considers the surrounding factors, for human use.  The computer system mentioned includes all hardware and software technologies whereas the system's users refer to humans in different environments such as the office, home, and school.

ISSUES ON COMPUTER USABILITY

  • Discussion of the use of computer hardware and software

HCI GOALS

The usability goals include the following aspects:

 The system should function optimally (factor of effectiveness).

 The system should function efficiently (factor of efficiency).

 The system should be able to be used securely (factor of secure-ability).

 The system should have the necessary utilities (factor of utility).

 The system should be easily learnt (factor of ability to learnability).

 The system usability should be easily memorised (factor of memorability).

IMPORTANCE OF HCI

  • Productivity - Interface helps users, especially changing from one to another tool, be more productive.

  • Security - Interface to be such that users are able to handle it well so as not to make tools dangerous weapons
