摘要

We have developed the Information Quantity Measurement method, which is featured byrncounting the number of information units (Chunk) exchanged between the user and thernsystem. This method is based on the assumption that "the less the information exchanged is,rnthe worse the usability of the system is". By using this method, we could foresee the situationrncontaining trouble sources. We applied this method to car navigation systems, and found outrnthe weak points of the systems from the standpoint of usability. The results have beenrncompared with the Usability Testing results to confirm the effectiveness of our method.
