It comprises: an optical unit set on the physical plane and configured to produce a first optical effect; an image acquisition unit set on the physical plane, at least a part of the optical unit being within an acquisition range of the image acquisition unit, a touch operation area being formed by the image acquisition unit and the optical unit; the image acquisition unit configured to capture an image having a second optical effect which is formed on the first optical effect after an operation body for operating the electronic apparatus enters the touch operation area; a processing unit being connected with the image acquisition unit and configured to determine the range of the operation body in the touch operation area according to the image having the second optical effect. The present invention also provides an optical touch input display apparatus and optical touch input positioning method. The touch system of the present invention is low-cost and highly reliable."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical touch system and method for optical touch location","description":"The present invention provides an optical touch system, applied to an electronic apparatus having at least a physical plane.
