Overview
ISO 9241-302:2008, "Ergonomics of human-system interaction - Part 302: Terminology for electronic visual displays," is an international standard developed by ISO. This document establishes a comprehensive set of standardized terms and definitions relevant to electronic visual displays. By providing consistent terminology, ISO 9241-302:2008 supports the effective communication, design, and evaluation of visual display technologies across various industries and applications.
This standard is a vital resource for professionals and organizations involved in the design, assessment, and implementation of human-system interfaces, ensuring that all stakeholders have a shared understanding of key concepts related to electronic visual displays.
Key Topics
ISO 9241-302:2008 covers terminology associated with:
- Photometry: Terms related to measurement of visible light from displays, including luminance concepts, contrast, and light distribution laws.
- Colorimetry: Definitions pertaining to the measurement and representation of color on electronic displays, including color spaces like CIE 1931 and CIE 1976.
- Geometry and Vision: Concepts about the physical and perceptual aspects of displays, including viewing angles and ergonomic considerations.
- Display Technology: Specific terms differentiated by technology types, such as LCD, CRT, OLED, and virtual-image displays.
- Virtual-Image Displays: Vocabulary for displays that create images perceived as being in a virtual position.
- Alphanumeric Symbols: Definitions for the representation and display of text and symbols on electronic screens.
This terminology is foundational for the other parts of the ISO 9241 series, ensuring clarity in measurement, performance characterization, and ergonomic evaluation of electronic visual displays.
Applications
ISO 9241-302:2008 terminology is widely used across a variety of sectors, offering practical value through:
- Display Development and Testing: Manufacturers and laboratories use standardized terms to describe measurements, test methodologies, and performance results of electronic visual displays.
- Human Factors Engineering: Ergonomists, UI/UX designers, and product developers reference this vocabulary to optimize user interfaces for safety, comfort, and usability.
- Procurement and Product Specification: Organizations rely on common terminology to specify product requirements, compare display technologies, and ensure compliance with ergonomic norms.
- Regulatory and Certification Processes: Regulatory bodies use standardized language from ISO 9241-302 to underpin requirements and certifications related to workplace safety and accessibility.
By aligning on terminology, professionals ensure better interoperability, reduce ambiguity, and facilitate the adoption of best practices for human-system interaction involving electronic displays.
