“Ashirase" is a wearable navigation system that assists the visually impaired with walking. The system consists of a smartphone app and an in-shoe vibration device including a motion sensor. The app receives data from the sensor and puts it together with map and satellite positioning information to generate navigational instructions, which the foot device communicates to the user through vibrations. Ashirase’s intuitive instructions via vibration can guide users to their destinations more safely without obstructing their hearing – a sense that is critical to the visually impaired.
