The automotive industry is still in the early stages of exploring the full potential of AI in HMI as the technology develops rapidly.
The future of automotive technology goes far beyond just user interfaces
Rightware’s Chief Technology Officer, Andreas Binner, recently appeared on NVIDIA’s AI podcast to share insights into the future of automotive technology and in-vehicle human-machine interfaces (HMI).
With a passion for infotainment and a strong background in the subject, Binner provides insights into the trends shaping the automotive industry and highlights the pivotal role of functional value for passengers in the HMI.
Over the past decade, the infotainment landscape has been transformed. Modern cars feature 3D visuals, internet connectivity, and ecosystem integration. Human-machine interfaces have evolved beyond pure user interfaces and have become an essential part of various car functions, such as rearview cameras, 360° surround view, and sensor/confidence displays.
“I’m still waiting for head-up AR-displays, which are like a window you look through. It’s just that you’re seeing a little farther,” Binner says enthusiastically. These would open up a whole new realm of possibilities for HMI design.
“Physical controls are being replaced more and more, which doesn’t please everyone. It can get a little bit overdone, so some go back to physical versions for that, which surprised me,” Binner points out when talking about surprising trends in HMI design. Not every button should be replaced.
Artificial intelligence has played a significant role in shaping human-machine interfaces in cars
Since first introduced, voice assistance has advanced from simple voice control to offering almost fully conversational interactions. Additionally, car AI could provide contextually aware functionality, such as the ability to recognize driving patterns at specific times of the day or week.
“Contextually aware AI can help the driver at the right time in the right situation, in whatever is needed. I think there’s a long way to go with AI in cars,” Binner notes. The industry is still in the early stages of exploring the full potential of AI in the HMI as the technology develops rapidly.
When adapting new technologies, trust plays a crucial role, which can be built with the help of the HMI
Trust plays a crucial role in the adaptation of new automotive technologies. The HMI can help to build trust between vehicle occupants and the technology, as the interfaces provide passengers with insights into the car’s hardware and software, as these components cannot be directly inspected.
“In a car, human lives are at stake. If machines are to control all the software and all parts of the car, we need to trust the technology not to fail in critical situations,” Binner emphasizes. Building the required trust can be achieved by providing functionality.
"HMI should focus on elements that have functional value for passengers, avoiding distractions and prioritizing necessary data. Additionally, HMI has the potential to enhance passenger experience by providing entertainment options for passengers and those sitting in the driver’s seat,” Binner states.
The role of the HMI will increase as autonomous driving continues to advance
Autonomous driving continues to advance, but human supervision remains necessary. In the future, when human drivers are no longer needed, human-machine interfaces will be vital for passenger reassurance and comfort.
“In the early days of elevators, elevator operators provided a sense of security. Similarly, HMI interfaces in cars can instill trust in passengers and ensure they feel safe and confident in the technology,” Binner says, drawing a parallel.
Looking ahead to the next decade, Binner predicts more contextually aware cockpits that focus on delivering relevant information at the right time.
“Striking the right balance between physical and tactile UI and virtual controls will be a key consideration for these cockpits. Meanwhile, functional value for passengers will remain at the forefront of HMI design, providing a seamless and enjoyable in-vehicle experience,” Binner notes.
