When a processor determines a capacitive coupling variation of a sensing point at a sensing panel of the touch sensitive device is smaller than a predetermined negative threshold or larger than a predetermined positive threshold, the processor then computes from local 2D sensing information of second 2D sensing information measured at the sensing point, to obtain a flatness index, The processor determine that the sensing point is not touched by any external object if the flatness index is between a predetermined flatness index negative reference value and a predetermined flatness index positive reference value that indicates the capacitive coupling amount at the sensing point is changed by the sensing point is not touched by any external object, whereby a false touch control determination due to removing water drop on the touch sensing panel can be prevented."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch sensitive device and touch determination method thereof","description":"The present disclosure relates to a touch control device and touch determination method thereof.
