A New Approach of Using Network Dialog Structures in Cars

摘要

To keep the numerous functionalities in luxury vehicles easily accessible and controllable while driving, sophisticated presentation and interaction techniques are absolutely necessary. In state-of-the-art systems, these functions are presently realized in a predominant hierarchical menu structure on a central car-display. Thus, several operation steps are required to reach a function X from a function Y. In this context, network dialog structures, as for example the link-based internet, can allow great simplification. For this reason, three different concepts have been developed and exemplarily implemented in a human-computer interaction concept: contextual, parallel, and user-defined menu and function access. In a usability study it has been approved that these three techniques of network menu access achieved great time savings in interaction. An average time saving of 32.5% compared to the use of hierarchical menu structure has been reached. A significant higher distraction effect from driving has not been noticed.
