<P>PROBLEM TO BE SOLVED: To provide a usability evaluation system for multidimensionally evaluating usability of a driver information system on a real time basis. <P>SOLUTION: The system for evaluating the usability of the driver information system comprises a data base, a driver information system implementation section and a user evaluation data collection section. The driver information system implementation section implements a prototype of the driver information system, detects data responsive to user operation during a user uses the driver information system, converts the detected data into data for usability evaluation and automatically stores them in the data base. The user evaluation data collection section collects subjective evaluation data of the user, converts the collected data into data for the usability evaluation and automatically stores them in the data base. <P>COPYRIGHT: (C)2005,JPO&NCIPI
