Due to the increased ruthlessness in road traffic, an interactive system called "MOBI“ was developed to address this problem.
The system makes use of the existing sensors of the motor vehicles and evaluates all actions in road traffic with the help of a rating system. In a future scenario, "MOBI“ will be established by the state in order to promote more responsible driving among all road users. Not only the system is able to evaluate an action, but also the driver himself. With the three controls on the steering wheel, anyone involved in road traffic can become active in a situation and evaluate a certain behavior of another driver. On the one hand, this can be done when driving responsibly by pressing the green button in order to evaluate this as a positive situation. On the other hand, in a reckless driving style by pressing the red button to evaluate a negative situation.
„MOBI“ was designed in such a way that the evaluations of the system and those of the road users carry different weightings. This helps to counter both fraud and bullying. In addition, gamification components were implemented. Each road user receives his own ranking, which can be improved by positive events and worsened by misconduct. Besides that the personal ranking of a road users also influences his everyday life, for example by adjusting fuel prices or insurance premiums. Consequently, the rating system contains a certain everyday incentive mechanism that makes a responsible driving style attractive. The evaluation system thus aims to create an increase in responsibility and cooperation in road traffic, as the actions and words of the perpetrator are directly linked to their identity and in addition there are everyday incentives.
By using "MOBI“, all road users can reach their destination with greater safety.

Creation of a logbook
Increasing attention of the people
should make "MOBI" redundant
Without being introduced by the state, the
system is not going to be appreciated

Storyboard short movie
With the sketching of a storyboard, the aim was to implement the film idea of each individual team member as clearly as possible. This had the advantage of forming a consensus among all team members, even in an international team. Especially in an international team language barriers can lead to different understanding. Finally, all concepts were brought together into a single concept and the final result was filmed.
What do current interfaces in vehicles look like? Which sensors are installed in the latest vehicles? And which head up display solutions are already available? These questions had to be answered first and foremost. For this purpose, the project group conducted a detailed internet search, which led to clarification of the current status quo.
How should your own system be designed?
The method of moodboarding was used to answer this question. Leading automobile manufacturers such as Daimler, Porsche, Audi and BMW inspired with impressive visions of vehicle components such as the interior. A collection of images was compiled into a collage, which influenced the visual design of the own system.
As part of the requirements analysis, use cases were generated that meet the requirements of the system behavior from the user's point of view. For this purpose, main and secondary scenarios were created that provided information about which properties are relevant for the system and therefore indispensable for the user.
Although the interface for "MOBI" was not done as usual on a haptic device, wireframes still had to be created. Using a low fidelity depiction, positions, contents and information were already brought to site and projected onto a windscreen with the help of a beamer. With the help of this abstracted
representation method the final implementation could take place.
