Eisma, Y.B. (author), Looijestijn, Anouk E. (author), de Winter, J.C.F. (author)In many domains, including air traffic control, observers have to detect conflicts between moving objects. However, it is unclear what the effect of conflict angle is on observers’ conflict detection performance. In addition, it has been speculated that observers use specific viewing techniques while performing a conflict detection task, but...journal article 2020

Kolekar, S.B. (author), de Winter, J.C.F. (author), Abbink, D.A. (author)Gibson and Crooks (1938) argued that a ‘field of safe travel’ could qualitatively explain drivers' steering behavior on straights, curved roads, and while avoiding obstacles. This study aims to quantitatively explain driver behavior while avoiding obstacles on a straight road, and quantify the ‘Driver's Risk Field’ (DRF). In a fixed-based...journal article 2020

Eisma, Y.B. (author), Borst, C. (author), van Paassen, M.M. (author), de Winter, J.C.F. (author)Objective: The aim of the study was to investigate the effect of augmented feedback on participants’ workload, performance, and distribution of visual attention. Background: An important question in human–machine interface design is whether the operator should be provided with direct solutions. We focused on the solution space diagram (SSD),...journal article 2020

Bazilinskyy, P. (author), Eisma, Y.B. (author), Dodou, D. (author), de Winter, J.C.F. (author)Objective: Research has shown that perceived risk is a vital variable in the understanding of road traffic safety. Having experience in a particular traffic environment can be expected to affect perceived risk. More specifically, drivers may readily recognize traffic hazards when driving in their own world region, resulting in high perceived...journal article 2020

Eisma, Y.B. (author), de Winter, J.C.F. (author)In the inspection time (IT) paradigm, participants view two lines of unequal length (called the Pi-figure) for a short exposure time, and then judge which of the two lines was longer. Early research has interpreted IT as a simple index of mental speed, which does not involve motor activity. However, more recent studies have associated IT with...journal article 2020

Bazilinskyy, P. (author), Dodou, D. (author), de Winter, J.C.F. (author)Future automated vehicles may be equipped with external human-machine interfaces (eHMIs) capable of signaling to pedestrians whether or not they can cross the road. There is currently no consensus on the correct colors for eHMIs. Industry and academia have already proposed a variety of eHMI colors, including red and green, as well as colors...conference paper 2020

Cabrall, C.D.D. (author), Happee, R. (author), de Winter, J.C.F. (author)For transitions of control in automated vehicles, driver monitoring systems (DMS) may need to discern task difficulty and driver preparedness. Such DMS require models that relate driving scene components, driver effort, and eye measurements. Across two sessions, 15 participants enacted receiving control within 60 randomly ordered dashcam videos ...journal article 2020

Krüger, Matti (author), Driessen, T. (author), Wiebel-Herboth, Christiane B. (author), de Winter, J.C.F. (author), Wersing, Heiko (author)With the rise of partially automated cars, drivers are more and more required to judge the degree of responsibility that can be delegated to vehicle assistant systems. This can be supported by utilizing interfaces that intuitively convey real-time reliabilities of system functions such as environment sensing. We designed a vibrotactile...journal article 2020

Doubek, F.H. (author), Loosveld, Erik (author), Happee, R. (author), de Winter, J.C.F. (author)In highly automated driving, the driver can engage in a nondriving task but sometimes has to take over control. We argue that current takeover quality measures, such as the maximum longitudinal acceleration, are insufficient because they ignore the criticality of the scenario. This paper proposes a novel method of quantifying how well the...journal article 2020

Eisma, Y.B. (author), van Bergen, Steven (author), ter Brake, Sjoerd (author), Hensen, Matthijs (author), Tempelaar, Willem Jan (author), de Winter, J.C.F. (author)In the future, automated cars may feature external human–machine interfaces (eHMIs) to communicate relevant information to other road users. However, it is currently unknown where on the car the eHMI should be placed. In this study, 61 participants each viewed 36 animations of cars with eHMIs on either the roof, windscreen, grill, above the...journal article 2020

Kolekar, S.B. (author), de Winter, J.C.F. (author), Abbink, D.A. (author)Current driving behaviour models are designed for specific scenarios, such as curve driving, obstacle avoidance, car-following, or overtaking. However, humans can drive in diverse scenarios. Can we find an underlying principle from which driving behaviour in different scenarios emerges? We propose the Driver’s Risk Field (DRF), a two...journal article 2020

Eisma, Y.B. (author), Hancock, P. A. (author), de Winter, J.C.F. (author)Objective: We review the sampling models described in John Senders’s doctoral thesis on “visual sampling processes” via a ready and accessible exposition. Background: John Senders left a significant imprint on human factors/ergonomics (HF/E). Here, we focus on one preeminent aspect of his career, namely visual attention. Methods: We present,...journal article 2020

(author)In the future, automated shuttles may provide on-demand transport and serve as feeders to public transport systems. However, automated shuttles will only become widely used if they are accepted by the public. This paper presents results of an interview study with 30 users of an automated shuttle on the EUREF (Europäisches Energieforum) campus in...journal article 2019

Zhang, Bo (author), Lu, Z. (author), Happee, R. (author), de Winter, J.C.F. (author), Martens, Marieke (author)In the context of automated driving, a monitoring request (MR) is a means to prepare drivers for a take-over event. However, driver compliance may be an issue because not all MRs require a take-over. In this study, we investigated how drivers’ compliance with MRs was associated with previously experienced scenarios. The compliance level was...conference paper 2019

Dreger, F.A. (author), de Winter, J.C.F. (author), Happee, R. (author)Freeway merging of heavy goods vehicles (HGV) is a safety–critical manoeuvre. However, at present, it is largely unknown how HGV drivers perceive and execute the merging manoeuvre, and how current advanced driver support and automation systems (ADAS) contribute. We performed semi-structured in-depth interviews with 15 HGV drivers to assess...journal article 2019

Matthews, Gerald (author), de Winter, J.C.F. (author), Hancock, Peter A. (author)We examine the continuing use of subjective workload responses to index an operator’s state, either by themselves or as part of a collective suite of measurements. Lack of convergence of subjective scales with physiological and performance-based measures calls into question whether there is any unitary workload construct that underpins...journal article 2019

(author), de Winter, J.C.F. (author)This study is the third iteration in a series of studies aimed to develop a system that allows driving blindfolded. We used a sonification approach, where the predicted angular error of the car 2 seconds into the future was translated into spatialized beeping sounds. In a driving simulator experiment, we tested with 20 participants whether a...conference paper 2019

Kovacsova, N. (author), de Winter, J.C.F. (author), Hagenzieker, Marjan (author)Introduction: Many bicycle–car crashes are caused by the fact that the driver fails to give right of way to the cyclist. Although the car driver is to blame, the cyclist may have been able to prevent the crash by anticipating the safety-critical event and slowing-down. This study aimed to understand how accurate cyclists are in predicting a...journal article 2019
