Description of Research Report: Effect of Cane Technique on Obstacle Detection with the Long Cane
Modern long cane (also known as the white cane) techniques have changed little since their development in the 1940s. The two-point touch and the constant-contact techniques are the two used most widely by travelers who are blind. Regardless of which technique is used, obstacle detection, a key component of preview offered by a long cane (Blasch, La Grow, & De l'Aune, 1996), is crucial for the safety of blind travelers. When obstacles such as construction cones or toys left on the sidewalk are missed, they may trip the cane user, resulting in falls and consequent fall-induced injuries.
