My project uses Doppler radar sensors in order to provide the user with movement, speed, and distance information of their environment. An array of Doppler radar sensors are placed on the user�s head and vibration motors are placed on the user�s chest, neck, back, and/or arms in order to provide input to the user without impeding any of their other senses. When something moves within about 25 feet of the user, the corresponding vibration motor for the particular direction relative to the user where the movement was detected will activate with a certain intensity to indicate how far away the movement was detected. In cases where an object is moving rapidly towards the user at a high speed, an emergency notification is sent such that all motors are activated and will pulse, while the motor corresponding with the direction the danger is in will be continuous and at a higher intensity to alert the user to where the danger is.
