Sensors may be disposed at the projector itself, at the projected image surface, or in a portable remote-control unit. Corrections may be applied as part of an original set-up process, or dynamically as the configuration changes. Image-stabilization techniques are utilized where applicable, as is the use of test patterns and the incorporation of “helper” signals into the video image. Tactile-sensing capabilities provide an interactive environment, and various packaging configurations for projection units and sensor provisions are disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Automatic correction of keystone distortion and other unwanted artifacts in projected images","description":"A system for manual or automatic correction of geometric or video image distortions introduced by projection onto obliquely angled or imperfect surfaces.
