Human Centric Design process is also called User-centered design process (UCD).
Human centric design processes for interactive systems, ISO 13407 (1999), states: "Human-centred design is an approach to interactive system development that focuses specifically on making systems usable. It is a multi-disciplinary activity."
In UCD, all "development proceeds with the user as the center of focus.
The User-Centered Design Process as follows:
• The users are in the center of a double circle.
• The inner ring contains: Context; Objectives; Environment and Goals.
• The outer ring contains: Task Detail; Task Content; Task Organization and Task Flow.
User-Centered Design (UCD) is a user interface design process that focuses on usability goals, user characteristics, environment, tasks, and workflow in the design of an interface.
UCD follows a series of well-defined methods and techniques for analysis, design, and evaluation of mainstream hardware, software, and web interfaces.
The UCD process is an iterative process, where design and evaluation steps are built in from the first stage of projects, through implementation.
The goal of UCD is to produce products that have a high degree of usability.
The usability objectives of UCD are as follows:
• Usefulness - product enables user to achieve their goals - the tasks that it was designed to carry out and/or wants needs of user.
• Effectiveness (ease of use) - quantitatively measured by speed of performance or error rate and is tied to a percentage of users.
• Learnability - user's ability to operate the system to some defined level of competence after some predetermined period of training. Also, refers to ability for infrequent users to relearn the system.
• Attitude (likeability) - user's perceptions, feelings and opinions of the product, usually captured through both written and oral communication.
