Abstract
Provided is a method including steps: (a) storing in a database an eigenvector and an eigenvalue for each recognizable gesture, with respect to a first signal input through a radar apparatus and a second signal resulting from removing background information from the first signal: (b) receiving a third signal from which to determine a gesture, as an input, from the radar apparatus: (c) removing background information from the third signal from which to determine the gesture to obtain a fourth signal: (d) computing an inner product of the eigenvector and a signal matrix relating to each of the third signal from which to determine the gesture and the fourth signal resulting from removing the background information from the third signal: and (e) comparing the computed inner product with the eigenvalue in the database, in which the eigenvector is extracted from signals of all recognizable gestures and the eigenvalue, and the eigenvalue for each recognizable gesture is an inner product of the eigenvector and the signal for a corresponding one of the recognizable gestures.
