TacBar

tactile bike navigation handlebar

Created 2018 at University of applied sciences Potsdam

TacBar was developed as part of my bachelor's thesis in Interface Design at the University of Applied Sciences Potsdam. The goal was to enhance bicycle navigation in urban areas by introducing an innovative solution that prioritizes safety and user-friendliness. The focus was on reducing distractions for cyclists during navigation.

The outcome is a bicycle handlebar equipped with integrated vibration and LED signals that provide tactile and visual navigation cues. The system uses two vibration motors and RGB LEDs embedded in the handlebar grips to deliver navigation instructions directly to the user, eliminating the need to look away from the road. Navigation is managed through a smartphone app that communicates via Bluetooth and allows users to calculate routes and choose different riding styles (e.g., relaxed or fast-paced).

The prototype was successfully developed and tested. Initial results indicate that tactile navigation can reduce accident risks while offering intuitive usability. TacBar stands out for its user-centered approach and the seamless integration of tactile technology with modern interfaces. This work lays the foundation for future advancements in bicycle navigation and holds significant potential for commercial application.
