| White Cane for the Visually Impaired |
The Indian Institute of Technology (IIT) in Delhi has developed a high-tech cane to assist the 9 million visually impaired individuals in the country with easier mobility.
The smart cane consists of two main components: a vibration mechanism to detect obstacles and ultrasonic devices to assist with public transportation usage. Equipped with detection and alert systems using impulse signals, this innovative cane can identify obstacles from the knee level upwards and can measure obstacles within a three-meter range. In contrast, traditional canes available on the market only detect pathways from the knee level down to a one-meter range. Alongside a user-activated radio frequency identification system, an impulse alert signal controller, and a battery-operated speaker, the smart cane can transmit radio frequencies to buses to determine their identification numbers and inform the user vocally. Users wearing headphones will receive the bus number and can navigate accordingly to the bus door.
However, a small electronic box must be installed at the bus door to respond to the radio frequencies emitted by the smart cane’s device.
