Apparently there is some research and development taking place into a cane that has a sonar or some similar sensor embedded into its tip, and transmits haptic feedback to the user via the handle. These assistive technologies are fantastic, but I wonder whether a vision-impaired person who has adapted to life before they were available would be weary about adopting them, on the basis that if it breaks or becomes unavailable that they would have maybe lost the skills and sharpness of other senses to compensate?
