standardvigu

Standardvigu is a formal open standard intended to guide the development, evaluation, and interoperability of graphical user interfaces across software platforms. It defines a common set of principles, metrics, and test procedures to assess usability, accessibility, and consistency of UI components and their behavior. The standard aims to help developers create predictable interfaces and to enable third‑party toolchains to interoperate with UI libraries and design systems.

Its scope covers widgets, controls, layouts, visual states, and interaction models across web, desktop, and embedded environments. Core principles include consistency, discoverability, feedback, error management, and accessibility. Conformance is expressed through three levels—Bronze, Silver, Gold—requiring progressively more rigorous criteria.

Technical specifications include a component manifest format describing supported properties and events, a minimal set of interaction patterns, a universal event taxonomy, and a conformance test harness that runs automated checks and, optionally, human evaluation. Metrics encompass task success rate, task time, error rate, user satisfaction scores, and accessibility indicators aligned with established accessibility goals.

History and governance: Developed by the Global UI Standards Council beginning in 2018, with major updates in 2020 and 2023. Maintenance occurs via a standing committee with a public repository, transparent consensus processes, and annual reviews that incorporate industry feedback and evolving accessibility expectations.

Adoption has grown in web component ecosystems, software toolchains, and automotive human–machine interfaces, where Standardvigu-certified UI kits are used to ensure consistent behavior across platforms and locales while supporting accessibility and internationalization requirements.
