ABSTRACT
The use of car navigation system is very common nowadays. Most of the car navigation services are based on turn-by-turn instructions and distance calculations. Academic research in this field has focused on evaluating basic usability. However, such products and studies have not covered users' various needs that arise in specific driving situations. For example, in a complex city space, drivers often face burdensome problems, especially when picking up pedestrians. We conducted a semistructured online survey asking specific problems, work-arounds, and their suggestions in picking-up situations. We grouped responses into several issue points based on their similarities and induced design implications for a car navigation system supporting picking-up situations. Through this user-centered design approach, we developed "Gravity - Automatic Location Tracking System between a Car and a Pedestrian" as a prototype and evaluated its usability, and we received favorable feedback.

Network-oriented road map generation for unknown roads using visual images and GPS-based location information
Car navigation systems (CNS) have become an interesting research and industrial topic due to their wide deployment. However, updating and distribution of the road map database is a complex and high cost process. In this paper, we propose a real-time map ...
Ant-based vehicle congestion avoidance system using vehicular networks
Vehicle traffic congestion leads to air pollution, driver frustration, and costs billions of dollars annually in fuel consumption. Finding a proper solution to vehicle congestion is a considerable challenge due to the dynamic and unpredictable nature of ...
