Abstract:
A method of controlling an operation mode of an electronic device and the electronic device therefore are provided. The method includes verifying an operation mode of the first electronic device when it is verified that a second electronic device is approached within a predetermined range while transmitting and receiving data with a third electronic device and changing a first mode to a second mode when the first electronic device operates in the first mode.
Abstract:
An apparatus for recognizing a user's motions based on sensor information and label information, a method for establishing an ONMF-based basis matrix, and a method for establishing an OSSNMF-based basis matrix are provided, where the basis matrices are used to extract motion features of the user. The apparatus for recognizing the user's motions may include a feature vector extractor configured to multiply a transposed matrix of an orthogonalized basis matrix by a sensor data matrix of frequency domain sensor data acquired from sensors to extract an ONMF-based feature vector and a multi-class classifier configured to use the extracted ONMF-based feature vector to classify the user's motion into a type from among types of a user's motions.
