In one embodiment the light source emits light in predominately blue wavelengths and the filter blocks at least 85% of light at approximately the same wavelengths. Visual information may then be beneficially written by a lecturer on the display screen using a fluorescent marker pen. In operation an image output of the video camera is reversed in left-to-right orientation so that visual image information written by a lecturer onto the display screen is reversed from an orientation of this information viewed through the display screen."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for presenting audio and visual information","description":"Method and apparatus for presenting audio and visual information to an audience by streaming, broadcast, live and recording presentations including a generally planar display screen, a light source di","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10523893","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
