Interacting with Navigation Devices: A Case Study

摘要

The paper aims to study the adequacy of interactive capabilities in commercial navigation devices. In order to do this, an experiment is proposed and two sets of results are obtained and analyzed: one resulting from the application of objective metrics; and the other one, from subjective answers of the device users when queried about their experience. To the extent that these interactive capabilities are found to be inadequate, it is the goal of this study to ascertain (l) whether a more natural, human-like interaction paradigm (i.e., natural interaction) ought to be incorporated into these kinds of devices and, if so, (2) the extent to which their interactive capabilities improve as a result. For this, a direct comparison of device interactive capabilities with those of human beings is neccssary. Study results suggest that the incorporation of natural interaction in navigation devices may help respond to certain device interactive inadequacies as well as to the user dissatisfaction which those inadequacies engender.
