The image detector senses the touching of the outer surface of the cursor-manipulating device with a pointing device, for example a finger, in which the outer surface comprises a light diffusing surface that allows the image sensor to capture and track an image of the pointing device touching the light diffusing surface in order to control a cursor of an electronic device. Multiple touching devices, like fingers, can be used to control simultaneous events on the screen of an electronic device, e.g. a notebook PC, cellular phone, game device and a GPS device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High resolution and high sensitivity optically activated cursor maneuvering device","description":"A cursor-manipulating device comprising a light diffusing surface, for example a Lambertian surface, covering a cavity containing a light source and an image sensor, wherein the cursor-manipulating de","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9720525","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.
