A Method for Designing Physical User Interfaces for Intelligent Production Environments
Table 2
Dependence between functional and nonfunctional requirements.
Functional Requirements (FR)
Non-Functional Requirements
Non-Functional Requirements for software ISO/IEC 9126-1
FR1-Qualitative and quantitative design recommendations on a more comprehensive level or quantitative design recommendations
Applicability, Inferability, and Universality
Functionality
FR2-Considerations of interactive products with multimodal interaction possibilities; Consideration of physical user interfaces, supporting the selection and configuration of appropriate mobile interaction devices
Inferability and Analysability
Functionality, Maintainability
FR3-Good presentation and visualisation of design recommendations as well as visualisation and communication of user scenarios
Applicability and Analysability
Reliability, Maintainability
FR4-Need for a comprehensive collection of significant design patterns for the description of physical user interfaces (mobile interaction devices), respecting the various facets and properties
Reusability and Extensibility
Usability, Maintainability
FR5-Integration and consideration of context information in respect to the work context in intelligent production environments
Adaptability
Portability
FR6-Focus upon industrial user interfaces and a broad audience of users in mobile working situations
