Higher levels of automated driving may offer the possibility to sleep in the driver’s seat in the car, and it is foreseeable that drivers will voluntarily or involuntarily fall asleep when they do not need to drive. Post-sleep performance impairments due to sleep inertia, a brief period of impaired cognitive performance after waking up, is a potent...

Future development of in-vehicle voice assistants (VA) aims at more adaptive and interactive interaction with users. One focus area is the development of proactive behaviour of VA. With the changing role from driver to passenger in increasingly automated vehicles, new opportunities for interactions with assistants in the car arise. However, potenti...

Information on novel interaction technologies is still being stored in a rather disorganized manner in many companies today, therefore, a more systematic approach is needed. Existing methods for standardized description of technologies focus the technological development approach and neglect human-centricity. To address this gap, the authors propos...

In automated driving it is important to ensure drivers’ awareness of the currently active level of automation and to support transitions between those levels. This is possible with $a$ suitable human-machine interface (HMI). In this driving simulator study, two visual HMI concepts (Concept $A$ and $B$ ) were compared with $a$ baseline for i...

The role of the driver changes to that of a passenger in autonomous cars. Thus, the vehicle interior transforms from a cockpit into a multimedia station and workspace. This work explores concepts for Artificial Intelligence (AI) to provide a personalized user experience for the passengers in the form of Contextual Personalized Shortcuts and Persona...

Positive user experiences (PUX) in the vehicle interior will be enabled by choosing the technologies with the potential to provide such experiences. Design for PUX in general exists, but methods to assess and compare technologies regarding their PUX potential are missing. Building on the insight that fulfillment of basic psychological needs may lea...

The Wizard-of-Oz (WoZ) paradigm is an established method in human factors research to investigate the interaction between human and new technology. In particular for automated cars this method is a useful and safe technique to collect data, simulate and investigate how autonomous, Artificial Intelligence (AI)-driven systems should be designed for o...

Working and being productive while commuting and travelling is a promising use case for automated and autonomous vehicles. Whereas different concepts have already been proposed how future interior concepts can support in-car work, user requirements for this use case were not investigated in detail. An online survey with n = 618 participants from al...

Automated driving is dramatically changing the way we perceive and control cars and lorries. In partially automated driving, the driver is still responsible for the vehicle control, but is strongly supported. In highly automated driving, the driver can give control and responsibility to the automation for a certain time and can get control back, e....

With the introduction of ADAS systems and vehicle automation, an interface informing the driver of the automation state is required. This study evaluates the suitability of a visual interface comprising up to 64 LEDs on the steering wheel perimeter; it displays continuous visual feedback about the automation state—including notifications of an unsc...

Automated vehicles are entering the roads and automation is applied to cars, trucks, busses, and even motorcycles today. High automation foresees transitions during driving in both directions. The driver and rider state become a critical parameter since reliable automation allows safe intervention and transit control to the automation when manual d...

Increasing automation is ongoing in all areas of transport. This raises new challenges for the design and training of Human-Machine Interfaces (HMI) for different user groups. The EU-project Drive2theFuture investigates the needs and wants of transportation users, operators, passengers and passersby to gain their acceptance and to set the ground fo...

The issue of driving performance after sleeping becomes highly interesting when introducing automated driving in Level 4 (SAE). It is known that fatigue as well as hypovigilance are severe risk factors for traffic accidents while an effective countermeasure is sleeping. In Level 4 automation sleeping while driving becomes a possible scenario, inclu...

Zahlreiche Systeme zur Abstandsregelung oder Spurführung auf der Autobahn und in urbanen Gebieten sind heute fest im Markt etabliert. Studien belegen, dass durch die Einführung der Systeme nicht nur der Fahrkomfort, sondern vor a...

Automated driving is no longer a future scenario. Several automotive OEM have already presented automated vehicles, which do not require driver's constant attention on the road. But, there are still some challenges to solve before series vehicles can pass from assisted driving to highly automated driving [1; 2]. A principal research question to dea...

Highly automated vehicles provide drivers with extra time for non-driving related tasks, such as getting involved in their digital lives. Different HMI concepts compete for offering the best digital experience in the car. We present a study which compared a handheld smartphone with a novel integrated in-vehicle HMI. This HMI consists of touch-press...

A new Human Machine Interface (HMI) concept - called Mobius - for automated driving, which enables drivers to keep their hands on the steering wheel while completing non-driving related (NDR) task, is tested and evaluated. A surprise takeover request reveals faster reaction times when either using Mobius or monitoring the traffic compared with usin...

The research about inattention and distraction is still struggling to answer all questions coming up from the automotive industry and politicians. A major reason for this is the partial approach in measuring driver inattention and distraction. Therefore a holistic approach with a reference model for driver distraction and inattention was developed....

Developing proof-of-concept solutions for new integrated rescue support systems is challenging, due to the different restrictions and procedures at different installation sites. One way of dealing with this conflict is the provision of one prototype for a mininum- and one for the maximum number of functions. This article presents a support module f...

The older generation is willing to use new technologies and innovations to improve their living and working situation. Therefore it gets more and more important to remove obstacles that prevent older people from using new technologies. Innovative workplace solutions can help elderly workers to be flexible in their working environment and therefore...

Due to their different risk assessment, e.g. running for a ball or pushing each other to the road, children are one of the highly endangered vulnerable road users. Most accidents occur on the way to school and close to the school bus stops. To protect children early information for car drivers may be helpful to slow down traffic before reaching a c...

Whenever an emergency situation occurs, a correct response of the rescue teams and an optimal communication and coordination among them is required to assure that all the people needing help are assisted within a short period of time.
