An electromagnetic handwriting system includes an electromagnetic handwriting tablet configured to receive a drive signal, the drive signal drives the electromagnetic handwriting tablet to be in a suspension state or an enable state. A frequency value at which the electromagnetic handwriting tablet enters the suspension state is set as a suspension state frequency threshold f0, A frequency value at which the electromagnetic handwriting tablet enters the enable state is set as an enable state frequency threshold f1. If an actual frequency value of the drive signal received by the electromagnetic handwriting tablet is set to ft, and a virtual frequency value fx is set to satisfy |f0−f1|>|f0−fx| and |f0−f1|>|fx−f1|, then when ft satisfies |f0−fx|>|f0−ft| and |f0−fx|>|ft−fx|, ft is adjusted to fx in response to driving the electromagnetic handwriting tablet."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electromagnetic handwriting system and electromagnetic handwriting input method","description":"The present disclosure discloses an electromagnetic handwriting system and electromagnetic handwriting input method.
