The control section obtains position information of a touch point on the touch panel at first time intervals, and determines a location of a sheet on the touch panel to obtain sheet location information, at second time intervals. The control section outputs the position information of the touch points and the corresponding sheet location information. The control section optionally calculates displacement amounts of the sheet on the basis of a change of the sheet location information, and outputs the position information of the touch points and the corresponding displacement amounts of the sheet. The control section optionally corrects the position information of the touch points on the basis of the displacement amounts of the sheet."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Handwriting input device, method for obtaining handwriting information, and non-transitory computer-readable storage medium","description":"A handwriting input device includes: a touch panel which can detect a touch given through a sheet of paper; and a control section.
