| With the increasing use of in-vehicle navigation systems, establishing and improving their usability is becoming important. While past research has focused on safety, ease of use, learnability, and memorability, little effort has been placed on understanding satisfaction. Knowing about user satisfaction is valuable as it reflects user's opinions on IVNS and supports improvements in these devices. This thesis proposes NaviQ, a user satisfaction evaluation tool for IVNS. NaviQ is a modified version of QUIS, an established satisfaction measurement tool. Modifications include removing unrelated questions and sections, and adding specific questions related to IVNS. NaviQ was deployed in a web-based survey of nine IVNS-related online communities. Results from 154 respondents were used to determine user satisfaction. Results indicate that both age and experience are significantly related to user satisfaction with IVNS. In addition, user satisfaction across a broad set of features is described and improvements to NaviQ are outlined. |
