Challenges in Dashboard Interactive Experience Design
1. Driving load
Driving load is the burden caused by the influx of large amounts of information on drivers due to limited cognitive resources. With the improvement of the level of automatic driving, the vehicle digital instrument panel has changed from a simple vehicle driving information display to a complex environment system that carries vehicle information and interacts with other information. In such a complex information system, the driver needs to switch between various state b2b data information in time in addition to obtaining road and vehicle condition information related to driving.
The National Highway Traffic Safety Administration divides autonomous driving into five levels, from the L0 driving level that displays basic driving information to a complex environment system that carries basic vehicle information, road condition information, and vehicle and other interaction information.
With the gradual improvement of the automatic driving level, the L2~L3 automation level is gradually improved, and the driving authority is gradually handed over; the driving level L4 driving level vehicles no longer need people to come to the instrument panel and disappear, replaced by more entertainment information.
2. Situational Security Awareness
The increasing degree of automation makes the driver feel safe enough, but to a certain extent, the driver lacks situational safety awareness. Under the existing technology, the autonomous driving that has been released in mass production can only reach the L3 level or even lower, which means that in some complex situations, the user needs to take over the control of the vehicle. Nowadays, traffic is changing rapidly, and users almost need to be vigilant all the time and be ready to "take over the pot" at any time.
Research from Stanford University shows that in Level 3 autonomous driving mode, the mental stress load on users is higher than that of ordinary driving, which means that users are more prone to fatigue and cause safety hazards.
3. Driver Emotions
Driver emotional state is an important factor in car driving. Emotions control people's actions, and "road rage" comes from this. Some driving behaviors, if negatively influenced by emotions, can pose a great safety hazard.
Vehicle digital dashboards differ from traditional mobile digital interfaces in that people use these devices to stare at the screen until they complete a task, but most of the use of digital dashboards is just a fleeting glimpse while driving. If it is due to poor usability of the in-car interface, it may have an impact on the driver's mood.
