The human and the interaction at the time of the development of the machine/the system which is done, standing in standpoint and point of view of the human who is used design.The fact that the machine/the system whose usability is high is made is purpose.
The effort such as that for a long time was done, human engineering,HCI, was researched in each field such as usability engineering and cognitive engineering. The human central design was lectured ???? A Norman who is the expert of cognitive psychology these as the solution which is shown in the fields which precede and the concept which integrates methodology, and others.
The user more concrete in explicit case, "the user central design (UCD)" with also the word which is said is used. Conversely in the sense that you aim toward the fact that "it is easy to use very in someone", it is connectedto the conceptof "universal design ".
The needs that, there is advanced multi-functionality of the computer and the computer on-board equipment and diversification of intended purpose of the Web sight in the background where method of thinking, human central design appears, "would like to use complicated ones more simply" is increasing. Process of the human central design was decided, when "ISO 13407" appears, this concept reached the point where attention is attracted, from each direction such as software development and Web policy.
for interactive systems"*, it was proposed by ISO in 1995 the English rough rag - ????? ????? of the engineering department university (Brian Shackel) the research of the human engineering system where the group which is centered does long time as a basis, was internationally standardized in 1999.
* As for the indian translation standard "JIS Z 8530:2000 human engineering - human central design process of interactive system"
With ISO 13407, specification of necessity of the human central design is requested first. Next it keeps turning four steps as consecutive process.
- Understanding of usage condition it states clearly
- Clear statement of requirement of user and organization
- Compilation of the solution with the design
- Appraisal of the design which is based on requirement
This, is based on the thought where you can design the purpose of the user and the machine/the system which is agreeable to quality usage condition (context of use) information, by circulating & shares with the user and the designer. Furthermore with ISO 13407 it requests also the service of the facility which does the usability test, the post for that and the arrangement of the staff and the execution etc. of education.
In addition, one "ISO/TR 16982:2002 Usability of the peripheral document methods supporting human-centred design " with, usability appraisal technique of 12 types is introduced.
User observation Document based method
Performance appraisal Model based method
Critical incident method Specialist appraisal
Question paper method Automatic operation appraisal
Interview
??????? method
Joint design appraisal
????????? method
The usability appraisal technique which is picked up with ISO/TR 16982
