2, characteristics of users
Characteristics of users refer to user types according to certain criteria and the common nature representing a certain type of users. The researching objective of users’ characteristics is to generalize common users into groups which are attached with different priorities to record the requirements of interface of these groups. Researching ways include direct communication, materials statistics, and surveys and so on. The definition principles of users’ roles are representative, relevant to function of same system and easy to analyze requirements about interface.
The final objective of requirement analysis about graphics design of
software interface is to serve for users. Requirements about graphics design
of software interface vary with cultural background, personal hobbies etc. of users. However, requirements about
graphics design of software interface are not as clear as business functions. Most users can not put forward any clear requirements about
graphics design of software interface and their requirements often change. The investigation of requirements of users about interface should choose users themselves as starting point to synthesize requirements from various groups and then define the most widely applied requirements.
Role definition of users is an application of man-machine engineer theory in software developing process. Based on users’ information and business experience, like aesthetic opinion, operative level of computer, working content of users etc. provided by system demanders, an initial definition of roles will be done and then some rectification and expansion would be added during requirement investigation.
3, requirement change
What users raise are only some basic and not necessarily scientific requirement of
graphics design of software interface. Users often according to their imaginary ideal system put forward requirements to developers. After delivering and operation of system, users tend to compare the realistic system with their ideal systems. At the same time, the use of realistic system would stimulate users to modify their imaginary ideal systems and put forward new requirements of
graphics design of software interface. However, the assessment of graphics
design of software interface has close relationship with cognitive level of users and other subjective elements like mentalities etc., so as to software interface, only after use can users put forward clearer requirements, like, whether it accords with his own operative habit, or whether its layout, color, typeface and some other content on
graphics design of software interface suffice his requirements.
4, draft of graphics design of software interface
In the early stage of software developing, because of vague requirements posed by users, it is difficult for developers to quantify, which leads to the neglecting of these vague requirements by developers. In order to solve this problem,
Toperfect graphic design company will draw a sketch or draft of graphics
design of software interfaceed according to users’ characteristics, which will help users quickly improve their own ideal models.
