The main objective of this study was to evaluate the usability of a newly developed automotive navigation interface
design and the existing automotive navigation interface design. Professional and non-professional Malaysian drivers were
recruited (N=60). Participants evaluated two types of automotive navigation interface prototypes (new and existing design), using
the Kansei usability survey, modified System Usability Scale (SUS) in a driving simulator. Task completion time and number of
driving errors were also measured. In the Kansei usability survey, the participants rated the existing and new designs as 3.456 and
3.893, respectively, on a 5-point scale. The SUS scores were 62.625 (existing) and 66.625 (new) and errors made while
navigating were 12.85 errors (existing) and 8.15 (new). The task completion time for the new design was less than the existing
design (2.34 min vs. 2.59 min). Overall, the new automotive navigation interface design prototype demonstrated higher levels of
usability compared to the existing design.
