Radar for the Blind

This paper document proposes a low cost solution for integrating ultrasonic sensors onto a white-cane and a hat, enhancing the detection capability of the visually impaired by providing haptic feedback to the user. Using the devices is made more intuitive by adding an attachment to the white-cane, a device commonly used by the visually impaired. The white-cane attachment detects objects above the white-cane while the sensor hat detects objects in front of the user.
