Abstract
Team NAVIGATE aims to create a robust, portable navigational aid for the
blind. Our prototype uses depth data from the Microsoft Kinect to perform realtime
obstacle avoidance in unfamiliar indoor environments. The device augments
the white cane by performing two signi cant functions: detecting overhanging objects
and identifying stairs. Based on interviews with blind individuals, we found a
combined audio and haptic feedback system best for communicating environmental
information. Our prototype uses vibration motors to indicate the presence of an
obstacle and an auditory command to alert the user to stairs ahead. Through multiple
trials with sighted and blind participants, the device was successful in detecting
overhanging objects and approaching stairs. The device increased user competency
and adaptability across all trials.
