Vibrating White Cane Tells Visually Impaired Users What's Around Them

The South Korean company Primpo has developed an improved cane for the visually impaired. It vibrates with increasing intensity as its sensor approaches an object. It can also detect colors:

Unlike conventional white canes, with which a user can not detect obstacles above waist height, the "Isonic" model can detect obstacles within a range of 25 degrees horizontally and 50 degrees vertically with an integrated supersonic sensor.

The product can also detect obstacles within a distance of 2 meters, as well as very slim objects, narrower than 3cm. With decreasing distance to an object, the cane's vibrating indicator sends a stronger signal to the user, pinpointing the location of the obstacle.

A feature to inform a visually impaired user of an object's color draws special attention. With a color sensor attached, the user is informed by voice messages of 10 detectable colors and their brightness, including red, orange and blue.
