The nuVision Jacket Prototype and Wrist Mount is designed with Kinect motion sensors in order to help visually impaired people better avoid obstacles and move around more safely. The nuVision Jacket uses Kinect motion sensors and alerts a user with haptic tactile feedback on the user's back. Users can tell the position and distance of an obstacle by the location and intensity of the vibration from a tactile feedback unit attached to a backpack. The processing unit is a laptop computer placed in the backpack. The wrist-mounted nuVision Armband uses a smartphone, its accelerometer and an attached ultrasonic sensor. The device has two detection modes. The ground level mode detects obstacles (both bumps and holes) on the ground based on distance from the ultrasonic sensor and the angle of the user's arm from the accelerometer. The above-ground level mode relies solely on information from the ultrasonic sensor.
