‘Rango’ – Makes White cane for visually impaired into a smart cane that can help avoid obstacles.

France-based startup GoSense has developed electronic device that can be added to a white cane for visually impaired to help avoid any obstacles.

By attaching it to a regular white cane, Rango allows users to sense and avoid any obstacles they may come across. It provides users with head to toe and shoulder-width protection. Rango is a fully virtual smart shield that protects users by locating and identifying obstacles that represent real danger. Used in combination with Wizigo’s features, it allows users to move around by themselves easily and safely. Rango’s many free updates ensure a continuous evolution of the product to meet users’ needs.

Rango works with ultrasonic sensors that can detect obstacles within a 2.5-metre radius. This is perfect for obstacles at mid-height, for example, that a standard white cane would be unable to signal.

As soon as an obstacle is detected, a 3D sound alert is sent to the user’s headphones, indicating where the obstacle is in relation to them. Note that Rango doesn’t signal all obstacles in the user’s vicinity, just those that the user is likely to collide with, which are usually the closest.

3D audio feedback
