SMART CANE TRAINING AT THE EMPLOYERS’ FEDERATION OF CEYLON By Manique Gunaratne

Smart Cane device is an electronic travel aid used in conjunction with a normal white cane that assists a visually impaired person in mobility and navigation.

While the normal white cane can only detect obstacles up to knee height, this device is capable of detecting obstacles from knee to head height. In other words, the Smart Cane is not meant to replace the white cane but to augment its functionality. It can detect obstacles up to 3 meters when used outdoor and up to 1.8 meters when used indoor. With this increased range, it warns the users about impending obstacles before possible collision happens and helps in finding collision-free paths.

The benefits of using the SmartCane device are as follows:

  • It helps to detect knee-above obstacles which are usually not detected by the white cane. Such obstacles might include a tree branch, underside of a car, hanging cloth strings, protruding window air conditioners, etc. As these obstacles usually pose a risk of injury to the head and upper part of the body, it is critical to detect them early.
  • It increases the detection range to 3 meters in the long-range mode and to 1.8 meters in the short-range mode. The enhanced detection range helps in informing the user about the presence of obstacles much before touching the actual obstacle. An object as big as wall and as small as a 3 cm wide raised pipe at 3 m can be detected from mentioned distance. This early detection helps in avoiding unwanted collisions.
  • It helps in finding collision free-paths while walking by detecting and avoiding obstacles.

 

In March 2015 The Indian Institute of Technology gave a smart cane training for a group of vision impaired persons at The Employers’ Federation of Ceylon. Ms. Manique Gunaratne is also a proud user of a smart cane.smart cane training
