Holistic and adaptivE Interface Design for human-technology Interactions


The HEIDI project is mainly focused on the fluid cooperation of internal and external Human-Machine Interfaces (HMIs), where the interaction between vehicles and vulnerable road users is crucial.

Recognizing the mutual intentions of pedestrians and (automated) vehicles is a challenge. Risky situations are difficult to predict and happen quickly – pedestrians crossing the road; children jumping out between parked cars; large and confusing intersections. Also, distracting dashboards and the lack of situation understanding further expose drivers and pedestrians to dangerous interactions. For this reason, a smooth coordination between internal HMI (iHMI) and external HMI (eHMI) must be established, which also requires the acceptance and trust of other road users. (The HADRIAN project specifically deals with drivers’ acceptance and trust in autonomous driving – News-).

The aim of the HEIDI project is to develop a cooperative HMI that combines internal and external sensors to create adaptive HMI solutions that, like a fluid, adapt to and support all road users and their needs. This cooperative HMI collects and updates driver’s’ and pedestrians’ data to understand the situation on the one hand, and on the other hand, to provide all stakeholders with recommendations for action that ensure safe interactions between vehicles and pedestrians.



The cooperative logic corresponds to the principle of Foresight Safety®, i.e. the human-like ability to anticipate hazards and proactively avoid dangerous situations. The interacting interfaces, internal and external, coordinate information and recommended actions for all user categories and adapt to their individual states and to the environmental conditions.



  • Develop and demonstrate fluid, cooperative HMI
    Concepts are developed to establish safe interaction between driver and pedestrian. To achieve this, internal and external HMIs are integrated into a cooperative HMI


  • Develop technical innovation for mutual awareness between road users and drivers
    – driver monitoring system: Sensors in the interior monitor the driver’s condition, such as tiredness
    – pedestrian monitoring system: Outdoor sensors collect and process data about the characteristics and behaviour of pedestrians, such as elderly people, children or groups of people.
    – situation assessment and decision module
    – situation resolution and tracking module


  • Develop suitable validation methods for assessing cooperative HMI solutions
    Specific multi-user simulation environments and research methods to evaluate the safety, usability & effectiveness of the cooperative HMI solutions will be developed and validated based on defined use cases.


  • Recommendations for regulation and standardisation of adaptive internal and external HMIs
    Guidelines and recommendations for future regulations and standards are prepared in order to create knowledge and provide informations about HMI to implement safe interface.

What is VIRTUAL VEHICLE’s role in this project?

VIRTUAL VEHICLE is the coordinator of the project and responsible for the project management and the presentation of the results. The research team will focus on the development and evaluation of the internal HMI and driver monitoring system.
