Abstract: A system for cross-acquisition of physiological and psychological information includes a test database, a user interface, a database, and a control unit. The test database stores various physiological and psychological questionnaires. The database stores physiological and psychological information inputted by a user or measured by an external apparatus or transmitted thereto from the outside. The control unit includes a matching module capable of accessing the database to perform correlation matching according to a keyword in a question in a selected questionnaire, and an acquisition module for acquiring matching information and for sending the same to the user interface. Through matching and computation, the system can display previously inputted or existing corresponding information when the user comes to a question that has been answered before so as to eliminate the need to repeatedly input the same information.
