Typically, the connected set of candidate three-dimensional locations comprising the three-dimensional location of the pointer is comprised in a structure indicated by the pointer. Therefore, the determined feedback on a three-dimensional pointer location on a view of the three-dimensional region of the image data improves clarity and decreases ambiguity of indicating a 3D location on the structure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"3D connected shadow mouse pointer","description":"The invention relates to a system (100) for determining a feedback on a three-dimensional location of a pointer in a three-dimensional region of image data, the system comprising: a display unit (110)","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8493389","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.
