Increasing Cyclist Road Safety
Representation of hazard notification for cuclists
Impact of notification on user experience, perceived safety and cycling behaviour


Challenges
Needs for Personas are quite different
Thin line between necessary information & overload
Implementing accessible features
Outlook
Implement camera on helmet to also see blind spots
Night mode
More personalisation (route suggestions, clothing options, …)
Gamification: connect with the community
Communication with helmet via speech
