User-Centred Requirements Handbook |
This section specifies details of the user interface that the system will offer to support each user group. This may include:
• an outline of the user interface structure, based on the system concepts
• example screens.
It should also record further details of the software that will be used to create each user-system interface (e.g. development package to be used, standards containing screen layout templates, etc.).
Process
1. Review all the potential user requirements identified in Stages 1 and 2, particularly in Form 1.6 Technical characteristics and 2.2 Design constraints. Copy those that relate to the software interface into Form 3.6 below.
2. Remove any requirements that duplicate others or do not seem relevant.
3. Add any new requirements which arise from the review of this section.
Please refer to RESPECT D4.2, section 2.2 which describes formal
characteristics of user interface specifications. Section 2.3 describes
a set of principles for user interface specifications based on the
concepts of task adequacy, self-descriptiveness, controllability,
conformity to user expectations, error tolerance, flexibility and
learnability. Section 2.4 presents an outline for documenting the user
interface.
