    "title": "Vortex xStream Speed Reading System",
    "inventor_name": "Clifford R. High",
    "publication_year": 1999,
    "device_name": "Vortex xStream",
    "goal": "Enable users to read electronic text at very high speeds by displaying one word at a time with customizable legibility settings.",
    "problem_addressed": "Traditional computer monitor displays require scrolling, fixed font layouts, and cause visual strain, limiting reading speed and comprehension, especially for users with visual or motor impairments.",
    "concept_summary": "Vortex xStream is a Windows-based software that extracts text from any application and presents it one word at a time on the screen. Users can set font, size, color, and display speed, allowing reading rates up to 2 000-3 000 words per minute while reducing eye movement and scrolling overhead.",
    "detailed_description": "The patented system (US 5,873,109) uses a microprocessor to (1) read the electronic document into memory, (2) sequentially update a one-word display region with the next word, and (3) accept real-time user adjustments of legibility characteristics via keyboard. The software runs on Microsoft Windows (XP, 2000, NT, ME, 98) and can pull text from browsers, email clients, word processors, and other software. It is marketed for use in education, government, business, medical, and assistive-technology contexts.",
