“…Generally, the passenger has played only a small or no role in the development of human-machine interfaces for road vehicles and there are only a few human-machine interfaces specifically designed for them. Most of these systems focus on infotainment (e.g., Meixner et al, 2017 ; Sen and Sener, 2020 ) or on information for the passenger which help to support the driver ( Maurer et al, 2014 ; Perterer et al, 2015 ; Trösterer et al, 2015 , 2019 ). As the former is usually independent of the current driving situation, this section will focus on research about the latter.…”

“…As the former is usually independent of the current driving situation, this section will focus on research about the latter. In studies by Maurer et al (2014) and Trösterer et al (2015) , the front seat passenger’s gaze is visualized in a driving simulation to improve communication and avoid misunderstandings with the driver during demanding situations like navigation or upcoming hazards. Supporting the passenger to take over tasks like navigation is intended to relieve the driver and their evaluation therefore focused mostly on driver benefits.…”

Development and evaluation of passenger assistance system concepts to reduce passenger discomfort

et al. 2023

The front seat passenger is often neglected when developing support systems for cars. There exist few examples of systems that provide information or interaction possibilities specifically to those passengers. Previous research indicated that the passive role of the passenger can frequently lead to a feeling of discomfort, potentially caused by missing information and missing control with respect to the driving situation. This paper investigates if and how different aspects of cognitive processes as defined in a previously published model can be approached with a technical system to reduce discomfort in passengers. Five prototypical passenger assistance systems are created which provide missing information (for example about the attentiveness of the driver) or the possibility to have more influence as a passenger. In a static simulator study with N = 40 participants, these systems were investigated with respect to their influence on measures of discomfort. Participants experienced in a counterbalanced order car following and braking scenarios on the highway with different time headways (within-subjects), with and without one of the passenger assistance systems (between-subjects). Based on the subjective measures for each experienced situation, three systems were identified as particularly useful in reducing discomfort. These displayed the attentiveness of the driver, the safety distance to a vehicle in front or provided the possibility to signal the driver that the recent safety distance is too small. These best proposals significantly reduced passenger discomfort in the tested Following and Braking scenarios for different time headways. In the post inquiry, more than 64% of the passengers confirmed the helpfulness of the rated system in reducing their discomfort in each case and about 75% of the passengers reported an interest in using it in their vehicle. This demonstrates opportunities to improve the everyday driving experience beyond classical assistance systems by explicitly considering the needs of passengers.

“…The display may also be confusing if the light cue is not well aligned with the passenger's line of sight to the object, making it hard to tell which object is highlighted. A calibration technique like the one presented by Trösterer et al [45] could help to alleviate this problem.…”

“…The visualized gaze of the passenger should make communication regarding directional information during navigation or upcoming hazards easier and more accurate which reduces misunderstandings. Trösterer et al (2015) investigated the influence of this assistant system on the communication between driver and passenger in demanding situations in a simulator study. They also compared this visualization of the passenger’s gaze to a more reduced design, in which the gaze is visualized with LED lights.…”

User Evaluation of Passenger Assistance System Concepts on Public Highways

et al. 2021

There is ample research on assistance systems for drivers in conventional and automated vehicles. In the past, those systems were developed to increase safety but also to increase driver comfort. Since many common risks have by now been mitigated through such systems, the research and development focus expanded to also include comfort-related assistance. However, the passenger has rarely been taken into account explicitly, although it has been shown that passenger discomfort is a relevant problem. Therefore, this work investigated the potential of passenger assistance systems to reduce such discomfort. Three different passenger assistant system prototypes were tested in a driving study on public highway with N = 19 participants. The systems provided information about parameters related to the performance of the driver and one additionally provided a communicative means of influence. For two passenger assistant systems, it could be shown that they significantly reduced passenger discomfort in at least a subset of the evaluated situations. The majority of participants rated one or multiple of the assistant systems as more comfortable than a ride without assistance. The system providing information about the attentiveness of the driver was most effective in reducing discomfort and was rated as the most helpful system. The results show that explicitly considering the situation of passengers in the design of assistance systems can positively impact their comfort. This can be achieved using information from common systems targeting driver assistance available to the passenger.
