NaviQ - A User Satisfaction Questionnaire for IVNS

In-Vehicle Navigation Systems (IVNS) are becoming common in luxury and rental cars, and low cost portable navigation units are popular aftermarket accessories. It is widely accepted that IVNS should be usable and user satisfaction is key to determining the success of IVNS. This paper proposes NaviQ, a user satisfaction evaluation tool for IVNS. Both general aspects of user interface design and specific aspects of IVNS are investigated and covered by NaviQ, and organized in a way such that they can be easily reused in order to build specific user satisfaction questionnaires for other in-vehicle information systems. NaviQ was deployed in nine online IVNS related communities. Survey results are presented and recommendations made.
