The Portable Indoor Localization Aid for the Visually Impaired is a prototype navigation aid designed to help Blind or Low vision individuals navigate their surroundings. The prototype consists of a foot-mounted pedometer and a white cane-mounted sensing package, which is comprised of a 3-axis gyroscope and a 2D laser scanner. There is a two-layered estimator that tracks the 3D orientation of the white cane in the first layer, and the 2D position of the user holding the cane in the second layer. An algorithm employs a known building map to update the user’s position, and exploits perpendicularity in the building layout as a 3D structural compass.
