Selena Chew, a student at the National University of Singapore, developed a futuristic white cane called BlindSpot. The cane has sonar and phone capabilities that make it perfect for the visually impaired. The device can detect objects that would normally be out of the reach of a traditional white cane - objects such as overhead tree limbs. In addition, it can be used to locate friends and family members via the built-in smart phone.
