ekraanilugematust

Ekraanilugematust, also known as screen reading, refers to the practice of extracting textual or symbolic information from digital displays for accessibility or data extraction purposes. The term originates from Estonian, where "ekraan" means screen and "lugema" means to read, with the suffix "tust" indicating an action. Screen reading technology is essential for users with visual impairments, as it allows for audible or tactile rendering of on-screen content through screen readers such as NVDA, JAWS, or VoiceOver. In business and research contexts, automated screen reading tools can harvest data from web pages, software interfaces, or printed documents scanned to digital images, often employing optical character recognition (OCR) and structured data extraction algorithms.

Key components of a screen reading system include rendering engines that translate visual layouts into accessible markup, voice synthesis modules that convert text to speech, and gesture or keyboard interfaces for input. Modern web standards, such as the Accessible Rich Internet Applications (ARIA) specification, provide semantic annotations that improve screen reader performance by clarifying element roles, states, and relationships. For automated screening of large datasets, screen reading often incorporates image processing techniques and machine learning models to handle non-standard fonts, handwritten notes, and dynamic content that changes without alerting assistive technologies.

The field has evolved rapidly with the integration of artificial intelligence, enabling more natural prosody in spoken output and improved text segmentation for mathematical notation and complex tables. Developers are encouraged to follow guidelines from institutions such as the Web Accessibility Initiative (WAI) and the National Institute on Standards and Technology (NIST) to ensure compatibility across devices and platforms. Screen reading remains a critical component of inclusive design, supporting equal access to information and interaction for the visually impaired community as well as facilitating large-scale data extraction in professional settings.
