LCTNav: a method for investigating collaborative navigation

Front-seat passengers can support drivers in navigational tasks, e.g., by giving instructions where to drive. Investigating the success of such collaborative navigation in the driving simulator is a challenge, as suitable navigation tasks are needed. Based on the basic idea and principles of the Lane Change Task (LCT, [4]), we created LCTNav, a method for investigating collaborative navigation in the driving simulator. With LCTNav lane change instructions are visualized on an external screen, which is used by the front-seat passenger. The question of \"Where to go to?\" in the real world is mapped to \"Which lane to change to?\" in the simulation. In this paper, we present and discuss the LCTNav method, which measures co-navigation in terms of driving errors and lane deviation.
