Abstract: Disclosed herein is a memory aid method of selecting data watched by a user, recording the selected data along with situation/behavior data upon watching, providing recorded audio/video data in response to a situation condition. The memory aid method may include receiving audio/video data from a wearable device, separating unit data including only associated parts from the audio/video data, and extracting character or feature data from the unit data. Object data and context data are generated from the character/feature data. Importance of the generated object and context data is determined with reference to a personal information DB. Audio/video data is stored depending on the importance. The method can record audio/video data recognized by a user at normal times, extract data necessary for a current situation, and provide the extracted data to the user. Accordingly, a user can accurately remember information that was watched in the past.
