NAVIGATION AIDS: A PREDICTIVE TOOL FOR INFORMATION DESIGN

摘要

Landmarks can potentially enhance the guidance provided by current vehicle navigation systems. However, there is a need to ensure that if landmarks are presented, only 'good' landmarks are chosen, since poor landmarks are likely to be detrimental to the driving and navigation task. A regression model was derived based on data from a requirements study into valued landmarks, and from subjective ratings of the factors likely to explain the effectiveness of landmarks. A model significant at the 0.05 level explained a total of 34% of the variance in the dependent variable, with the most important factors being the degree to which a driver interacted with the landmark, the usefulness of its location, and its visual characteristics. Further analysis will be carried out to try to improve the predictive power of the model, before providing recommendations to industry.
