A Study on the Design of Voice Navigation of Car Navigation System
This study tries to find the designing blind spots of the voice prompt function in the current car navigation systems and make improvement suggestions. The experimental plan was implemented through videotape analysis of the voice-prompt mode, referring to Urban Road Classification Regulations and the questionnaire survey results. Driving simulation tests were conducted with 15 experimental subjects, 13 road combinations, and 3 running speeds, and different prompt modes which were run synchronously were also included. Compared with the present mode (prompt time is determined by distance.), the newly-designed mode (prompt time is determined by running speed.) significantly improved driving performance and reduced mental workload. When driving on a main artery with fast lanes and slow lanes, adding a changing-lane prompt with a clear sound to the system can help increasing the driving accuracy rate.
