Made-in-Vietnam smart cane for the blind
Blind people in Vietnam now can walk safely with made-in-Vietnam mobile aid walkers called folding smart canes, reported Thanh Nien reporter To Tam.
Equipped with a receiver that detects infrared rays radiating from physical objects, the smart cane can help a blind person locate obstacles while he walks, said designer Mr. Dau Hoa Vang of Ho Chi Minh City.
The equipment is capable of recognizing objects in a radius of 0.5 to 1 meter with a 45-degree scanning angle. When obstacles are detected, the cane’s handle will vibrate. In addition, another special small vibrator can be attached to the user’s hat, glasses or pockets.
The cane is powered by a nine-volt battery and the power supply base is placed to make it easy for users to change the battery. When not being used, it can be folded easily.
Mr. Vang, the inventor of the mobile aid, said he would add more functions to his product including sound alerts and object shape detectors.
