The present invention provides a portable sensing and operational device, which uses a sensing module to receive a sensing signal transmitted by a sensor, and produces a sensing datum correspondingly. Then, an operational circuit operates a first matrix and a second matrix according to the sensing datum. The first matrix corresponds to a plurality of maximum values； and the second matrix corresponds to a plurality of minimum values. The operational circuit operates to generate at least a component by decomposing the first matrix and the second matrix. The component is provided to an output circuit for outputting the component to an electronic device.本發明為一種可攜式感測運算裝置，其藉由一感測模組接收感測器所傳送之感測訊號，而對應產生一感測資料，並透過一運算電路依據該感測資料運算出一第一矩陣與一第二矩陣，第一矩陣對應於複數極大值，第二矩陣對應於複數極小值，運算電路藉由第一矩陣與第二矩陣之分解運算進而運算出至少一分量，以供輸出電路輸出該分量至一電子裝置。
