DIN EN ISO 9241-143 provides requirements and recommendations for the design and evaluation of form-based dialogues - in which the user fills-in, selects entries for, or modifies labelled fields on a "form" or a dialogue box presented by the system. Often the system then creates, or updates the data associated with the form. Form-based entries typically are in the form of typed input (abbreviations, or full names) or selections from available option lists. DIN EN ISO 9241-143 is applicable to form-based dialogues regardless of the modality in which they are rendered (visual, spatial, vocal). However, much of the guidance is based on a model of visual and spatial relationship. In addition, DIN EN ISO 9241-143 specifies the use of non-text methods for providing forms entries (e. g., list boxes) and pertains to dialogue boxes which utilize form-based dialogue techniques. Guidance is provided on the selection and design of those user interface elements relevant to form-based dialogues. While lists used to enter forms data are covered in DIN EN ISO 9241-143, menus which are similar to lists are not covered in this standard but are covered in DIN EN ISO 9241-14. In addition, DIN EN ISO 9241-143 does not cover the hardware aspects of form-based dialogues. The requirements and recommendations in DIN EN ISO 9241-143 are applicable throughout the development process (e. g., as guidance for designers during design, as a basis for heuristic evaluation, as guidance for usability testing) and in the procurement process.
