The auto industry is going through the biggest upheaval since the invention of the automobile. Digitization, networking, semi-autonomous driving functions, and, above all, the rapidly changing user behavior of people require new mobility concepts. The automobile is becoming the much-cited “smartphone on wheels.”
In the future, highly automated vehicles will offer occupants more space for relaxation and entertainment and serve as a partner who interacts via intelligent language assistance, 3D displays, and innovative functions. A positive user experience (UX) is essential for the success of new vehicles today. This means that the development of new automobiles is becoming increasingly complex.

“A major challenge is to anticipate what people will want, need and expect from communication, entertainment content, and mobility solutions in five to ten years and beyond,” explains Guido Meier-Arendt, Human Machine Interface (HMI) Principal Expert at Continental. “To do this, we must rethink mobility. For example, we will increasingly offer cloud-based services in the future. The automobile becomes part of a mobility network in which different road users communicate seamlessly with each other. This creates a holistic and safe mobility experience.”
“As a technology company, we have to find out what people really need – even if they may not be able to articulate this themselves. In addition to systematically involving the user in technology development, we also apply approaches to HMI vision development,” explains Meier-Arendt. Future studies, current usage trends – such as popular consumer electronics and video gaming – as well as a wide range of cultural, sociological, and demographic factors, are analyzed and taken into account. This gives the Continental experts an initial idea of which solutions will make mobile life safer, more convenient, and more efficient in the future.
Industry sources added that Continental follows a user-centered development approach: the needs of people are at the center of all technological developments. While that sounds obvious, it is an extremely complex task. “The first step in every development is to understand the user and their context,” says Guido Meier-Arendt. “The crux of the matter is that needs and expectations depend both on the current situation and on enduring user characteristics.”
Psychologists are crucial for a positive user experience
In order to not only develop this strategy but also adapt it in the daily development of real-world applications, Continental employs engineers, IT experts, and specialists for artificial intelligence and big data in its research and development centers around the world, as well as media, graphic designers and traffic psychologists to best understand future user needs.
An expert on user behavior is Sebastian Weiss, a psychologist who specializes in human factors research. Weiss studied psychology in the master’s program “Human Performance in Socio-Technical Systems” and is a sought-after specialist in engineering and traffic psychology. For Continental, he traces the needs of people and the users of tomorrow and translates that into recommendations for future technology solutions. However, it is not feasible to directly ask all users about their mobility wishes and needs; therefore Weiss and his team have an extensive portfolio of psychological communication processes and high-tech laboratory equipment at their disposal.

In the virtual reality laboratory, subjects test innovations in simulated traffic worlds. There is even a converted premium limousine that offers a 180-degree view from a real cockpit of virtual road situations that are shown on large monitors in front of the demonstrator. “We accompany new developments, especially for human-machine interfaces, from the first concept phase until just before they are ready for series production,” explains Weiss. “The decisive factor here is always to see people at the center of all considerations and experiments.”

In every phase of development, users test the new technologies and undergo extensive interviews. Continental’s HMI team seeks to create user experiences that are intuitive, understandable, efficient, and increase safety. Above all is the question: Do people have confidence in technology?
“Trust is a crucial factor,” says Continental HMI expert Meier-Arendt. “The more vehicles that are highly automated and will also operate fully autonomously in the future, the more important it is for users to trust the technology. One of the greatest challenges in modern automotive engineering is to develop concepts and solutions that give people the feeling: You are safe here; you can rely on the technology one hundred percent.”
Autonomous test drives in the “Wizard of Oz” vehicle
How does technology have to be designed so that people can trust it? In order to receive realistic feedback on the effect of new products, the developers at Continental, in cooperation with the in-house psychologists, use so-called “Wizard of Oz” vehicles. Test subjects are told that they are driving an autonomous steering car – although behind a curtain on the passenger seat is a Continental engineer steering the car via right-hand drive. The behavior of users was tested and recorded with a deceptively real-looking autonomous drive. Test subjects were instructed to make phone calls, type text messages, eat and drink, and even turn to the back seat. An artificially intelligent algorithm was trained to generate a suitable response from the intelligent monitoring and HMI system for every user status in the cockpit. For example, if the user’s head was turned backward, the seat vibrated to draw attention to a warning display. Alternatively, audio warning signals were played. Afterward, in intensive psychological interviews, it was determined which situation and which feedback the test subjects feel safest and most comfortable with.

In another experiment, the interaction of pedestrians and cyclists with autonomously driving cars and delivery robots was tested. For this, Weiss and his team equipped the test subjects with virtual reality glasses. In artificial but realistic street scenes, virtual vehicles were equipped with various warning light systems. Sometimes warning lights shone green or red on the hood, and sometimes lights were attached around the body of the vehicle. “Protecting vulnerable road users is central to Continental’s development work,” said Weiss. “But we can only see whether a proposed solution works in tests with real people – in the safe environment of a virtual world, of course. How do people interact with autonomously driving vehicles? Which signals encourage people to cross the street, which ones to stop, and which ones might confuse them? Does only the pedestrian detected by the autonomous system move, or does the cyclist hidden by the truck in the adjacent lane also feel addressed? Can statements about autonomous cars also be applied to other mobility solutions such as delivery robots? These are the questions we seek to answer with our technology solutions.”
Technologies with real value-add create a positive user experience
The results from the extensive tests and psychological surveys flow into the concrete design of new HMI solutions. This is where experts like Jochen Möller, Senior Expert in User Experience & Interaction Design at Continental, come into play. Möller, a media system design graduate, and his team of engineers and designers primarily develop innovative display technologies. “Our goal at Continental is to develop technologies that create real added value for the user. It can be very practical, such as being able to make payments from the car via an intelligent display. But emotional added value is also essential for a positive user experience, for example, if the presence of a surface or a rotary knob simply feels good.”
When such an added value is offered, whether the user appreciates the creative work of Möller, is then determined again in extensive user tests. The interest of customers, who of course conduct market research themselves with the support of psychologists, is an indication of the probable success of a development. Another indicator is the recognition of industry awards. Several display innovations from Continental recently received awards. For example, the technology company received the CES Innovation Award for its Driver Identification Display. The driver identification display from Continental and its partner trinamiX is the world’s first automotive display for the vehicle interior that enables contactless, secure authentication of the user and increases comfort in the automotive sector.
