The IR illumination at the display may be either a flood of light or structured light. In some implementations, stereo vision based imaging techniques may be employed in conjunction with an auto-aligned IR floating image to provide illumination for a stereo imaging system and to provide position sensing for interaction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Auto-aligned illumination for interactive sensing in retro-reflective imaging applications","description":"Interactive sensing in retro-reflective imaging systems may be enabled through auto-alignment of an infrared (IR) illumination region with a floating image region by transmitting IR light, added on or","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9612687","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.
