Description

<p>We investigated how participants searched information in onboard information system. In this study, we addressed the following three questions: (1) Whether participants find the information more quickly and efficiently after the training than before? (2) Would they acquire knowledge of information structure? (3) Which factors in uence their evaluation of system? The results of experiment showed that the participants improved their information search very quickly. However, searches for untrained information were not so quick and effective as searches for trained information. The participants acquired little knowledge of an information structure. From the results of experiment, there was a possibility that difficulties that the participants faced in the first part of training in uenced an evaluation of the system.</p>
