In this paper, we classify existing research of pedestrian navigation system including smartwatch on HMI (Human-Machine Interface) and evaluate HMI by experiments in order to realize a mobile / wearable / infrastructure collaborative operation based pedestrian navigation system. First, we classify the navigation information and the presentation method used in existing pedestrian navigation systems, including the use of smartwatches, and input to the system by screen operations. Next, we clarify the role of the smartwatch in the pedestrian navigation system considering the characteristic features of the smartwatch, and do a subjective experiments to design an HMI according to the role. From the results of the subjective experiments, the navigation information to be presented on the smart watch and the presentation method are determined. Consequently, the knowledge on pedestrian navigation system using smart watch are obtained. |
