摘要:
A system for a user authentication includes an odor sensor unit for sensing an odor of a user's body to generate an odor biometric information vector, and a learning unit for performing an initial learning using the odor biometric information vector to generate a comparative odor biometric information vector. An authentication unit performs the user authentication by comparing an odor biometric information vector of the user's body to be authenticated from the odor sensor unit with the comparative biometric information vector if the user authentication is required. The authentication unit further performs an incremental learning of the comparative odor biometric information vector using the odor biometric information vector used in the authentication to create an incrementally learned odor biometric information vector. The comparative odor biometric information vector is updated with the incrementally learned odor biometric information vector.
摘要:
A user manual supporting method for use in an electronic appliance includes converting a series of operations performed by the user to operate the electronic appliance and converting the operations into a pattern of user operation sequence, and checking if an error is present in the pattern of user operation sequence to retrieve a pattern of erroneous operation sequence corresponding to the pattern of user operation sequence having the error. Thereafter, a manual content associated with the pattern of erroneous operation pattern is extracted and the extracted manual content is provided to the user. The manual content the manual content includes text and/or graphics information for notifying the user of a missing operation in the pattern of user operation sequence, or for guiding a normal operation against the pattern of erroneous operation sequence.
