Sometimes called as Man-Machine Interaction or Interfacing]]> 2021-06-08 04:30:47 UTC https://padlet.com/zulhusniderman/pstdpo28pmkyaome/wish/1591879964 Functionality and Usability zulhusniderman https://padlet.com/zulhusniderman/pstdpo28pmkyaome/wish/1591893619 Functionality
- the set of actions or services that it provides to its users (provides function needed by users to perform their tasks).
- visible only when it becomes possible to be efficiently utilized by the user.
Usability
-the range and degree by which the system can be used efficiently and adequately to accomplish certain goals for certain users.
- achieved when there is a proper balance between the functionality and usability of a system (Ease of use and learnability).

HCI is a design that should produce a fit between the user, the machine and the required services in order to achieve a certain performance both in quality and optimality of the services.

- a user interface design process that focuses on usability goals, user characteristics, environment, tasks, and workflow in the design of an interface.
-follows a series of well-defined methods and techniques for analysis, design, and evaluation of mainstream hardware, software, and web interfaces.

(Jeffrey Rubin):
- Development proceeds with the user as the center of focus

(ISO 13407
:1999, revised by: ISO 9241-210:2010)
- an approach to interactive system development that focuses specifically on making systems usable. It is a multi-disciplinary activity.
