A recognition device of a foot action includes a sensing module, a processing module, and a display module. The sensing module senses the foot action to generate at least one sensing signal corresponding to the foot action, and a form of the sensing signal is a waveform. The processing module is electrically connected the sensing module. The processing module recognizes an action mode corresponding to the foot action according to the waveform and converts the waveform into output data according to the action mode. The display module is electrically connected the processing module and displays the output data. Furthermore, a recognition method of the foot action is also disclosed herein.一種腳部動作之辨識裝置包含感測模組、處理模組及顯示模組。感測模組用以感測腳部動作以產生相應於腳部動作的至少一感測訊號,其中感測訊號之形式為波形。處理模組電性連接於感測模組,用以根據波形辨識相應腳部動作的動作模式,並轉換波形為相應於動作模式之輸出資料。顯示模組電性連接於處理模組,用以顯示輸出資料。再者,一種腳部動作之辨識方法亦在此揭露。1‧‧‧辨識裝置11‧‧‧感測模組12‧‧‧處理模組13‧‧‧顯示模組14‧‧‧儲存模組15‧‧‧傳輸模組2‧‧‧接收裝置21‧‧‧接收模組22‧‧‧微處理器23‧‧‧顯示單元
