Abstract
A sensing method for detecting a sensing array is provided. The sensing array comprises at least one sensing row. The sensing method comprises the steps of: obtaining a sensing curve according to a plurality of sensing data signals extracting from the sensing row; determining whether a curve feature of the sensing curve matches one of a plurality of predetermined curve features; and obtaining a touch condition of the sensing row according to the determination result related to the sensing row. A sensing device is further provided. The present invention can reduce the impact of interference noise on detection of a sensing array, and enhance accuracy of detecting a touch condition of the sensing array.
