A study on user acceptance of error visualization techniques
Location-based services in general require information about the position of certain objects. For instance, for a navigation service the position of the user needs to be known. This position is usually provided by a positioning system. However, it is typical for all positioning systems that they are not perfect. This means that the positions they produce inherit position errors. Nowadays, usually only the position estimate is shown to the user even though a quality measure for the position error is provided by most positioning systems. To increase the user’s trust in location-based services and the usefulness of these services, the user should be informed about the uncertainty of position estimates as well. Thus, in this paper we investigate different visualization methods for the position and the position error. We carried out a user study to obtain information about the usefulness of the different methods. For this, we developed a questionnaire that contains nine different positio...
