Truck developers - and drivers -
can benefit from human-factors
experts' efforts to design interfaces
that simplify information processing
and reduce cognitive load.
T
he advancement of vehicles with enhanced
safety and infotainment features has made
evaluating human-machine interfaces (HMI)
in modern commercial and industrial vehicles
crucial. Drivers face a steep learning curve due
to the complexities of these new technologies.
Additionally, the interaction with advanced driverassistance
systems (ADAS) increases concerns about
cognitive impact and driver distraction in both passenger
and commercial vehicles.
As vehicles incorporate more automation, many
clients are turning to biosensor technology to monitor
drivers' attention and the effects of various systems
and interfaces. Utilizing neuroscientific principles
and AI, data from eye-tracking, facial expressions
and heart rate are informing more effective
system and interface design strategies. This approach
ensures that automation advancements improve
rather than hinder the driving experience.
The integration of HMI systems in vehicle design is
evolving rapidly, focusing on enhancing user-vehicle
interactions. A deep understanding of human-factors
engineering is essential for creating safe, efficient
and user-friendly driving experiences.
Companies like iMotions and SmartEye are using
behavioral research and eye-tracking to pioneer new
HMI design principles.

manager and senior neuroscience
product specialist for iMotions.
" Truck companies
are increasingly
utilizing these
technologies to
incorporate humanin-the-loop
systems
that improve overall
driving safety. "
The role of neuroscience
in HMI design
Human factors are critical in designing
HMIs for transportation systems,
with designs needing to accommodate
the abilities and limitations of
human drivers. This involves ergonomic
design, cognitive psychology
and user experience (UX) research to
develop interfaces that are userfriendly,
safe and intuitive.
The aim is to create systems that
align with human behavior and cognitive
processes, reducing errors and
improving usability. Advances in neuroscience
have greatly enhanced the
tracking, assessment and design of
HMIs, moving beyond traditional interview-based
methods to more sophisticated,
neuroscience-based techniques.
Modern approaches include using
camera-based eye trackers like
SmartEye Pro, AI-powered facial expression
analysis tools like Affectiva's
Affdex, and methods like electrodermal
response and electrocardiography
