Abstract: This paper introduces a smart shoe that helps people move around inside buildings using gentle vibrations. Instead of relying on GPS or online maps, it tracks steps and direction with the phone’s built-in motion sensors. The method used is called pedestrian dead reckoning, which figures out position based on movement patterns. A matching app made with Flutter holds custom digital floor plans for different places indoors. Users can plan paths or get guided directions straight from their phone. Commands are sent wirelessly to small computers in each shoe using Wi-Fi signals. These tiny controllers then turn on one of two vibrating pads per foot – indicating turns or when they’ve reached the spot. The setup offers a complete, standalone way to navigate – ideal for indoor demos, restricted areas, or studies helping people with vision loss. Tests show it guides users step by step with precision while giving steady touch-based alerts on the go, proving that wearable navigation using only PDR can work reliably, no outside systems needed.
