Latest Patents

Choi's latest patents include a method and apparatus for recognizing motion features of users using orthogonal semisupervised non-negative matrix factorization (OSSNMF)-based feature data. This innovative apparatus is designed to recognize a user's motions based on sensor information and label information. It provides methods for establishing an ONMF-based basis matrix and an OSSNMF-based basis matrix, which are essential for extracting motion features of users. The apparatus includes a feature vector extractor that multiplies a transposed matrix of an orthogonalized basis matrix by a frequency domain sensor data matrix to extract an ONMF-based feature vector. Additionally, it features a multi-class classifier that utilizes the extracted feature vector to classify the user's motion into specific types.

Another notable patent is for an electronic device that detects information about a person on the other end of a call. This method involves a first electronic device synchronized with a second electronic device, which receives a call from a third electronic device. It detects information related to the third device and transmits this data to the second electronic device.
