Dashboard design in passenger cars is not only important in transferring the interior design image that the consumer feels, but is also an essential influence on the reading efficiency to gadget reading efficiency, which in turn is related to safety. This study, using an eye-tracking system to obtain accurate data for analysis, attempted to measure the visual power of dashboard in passenger cars and identify the relationship with dashboard design type.
The experiments comprised three parts. A pre-experiment concerned the standard processes and the setting up of the experimental space for the main experiment. The second experiment determined 25 sample dashboards for different gadgets. Finally, in the main experiment, 25 samples were shown using a projector to 23 college students individually, three tasks were assigned, and the processes of detail viewing were recorded via an eye-tracking system.
Applying one-way ANOVA and Quantification 1 Analysis to explore visual power data from the main experiment yielded the following results: 1) changes to the dashboard were associated with changes in visual power], 2) the outline of meter on dashboard was identified as the most important influence on visual power, in terms of both subjective assessment and eye-tracking data, followed by the horizontal and vertical distance of 3 meters.
