“…In their design guidelines for the usage of ambient light systems [16], they further state that the position of an LED visualization is one of the essential parameters. An approach to increase the accuracy of LED visualizations was introduced by Trösterer et al [29], who showed that accuracy could be increased by conducting an individual calibration procedure for the driver.…”

“…In order for the setup to work, an LED calibration (cf. [29]) and gaze mapping procedure needed to be performed. This was done in four steps: (1) Driver and front-seat passenger agreed on two distinct points in the environment, which could be perceived by both and could be mapped to the LED-strip (preferably in-plane in about 5-10 meters distance to the car).…”

The front-seat passenger in a vehicle may assist a driver in providing hints towards points of interest in a driving situation. In order to communicate spatial information efficiently, the so-called shared gaze approach has been introduced in previous research. Thereby, the gaze of the front-seat passenger is visualized for the driver. So far, this approach has been solely investigated in driving simulator environments. In this paper, we present a study on how well shared gaze works in a real driving situation (n=8). We examine identification rates of different object types in the driving environment based on the visualization of the front-seat passenger's gaze via glowing LEDs on an LED-strip. Our results show that this rate is dependent on object relevance for the driving task and movement of the object. We found that perceived visual distraction was low and that the usefulness of shared gaze for navigational tasks was considered high.
