Engineering students at Texas A&M University have developed an attachment that turns and ordinary white cane into a powerful navigation device. The attachment, known as the Navigational & Object Visual Assistant (NOVA), uses haptic feedback via vibration motors alerting the user to any above the waist obstacles. NOVA also interacts with a specially designed mobile application designed to give turn-by-turn navigation. Remarkably NOVA uses no audio signals, instead using vibration from three separate motors (left, right, & center) to signal whether a turn or an obstacle is approaching.
