Above-the-knee obstacles: The White cane can’t detect any obstacles above knee-level such as tree branches.
Range of obstacle detection: The white cane only warns of obstacles in the immediate of the person thus at times not enough time to respond in evading the danger.
Discrimination: There is a lot of discrimination that has been tagged to the use of the white cane. A visually impaired user described it as walking with a flag and waving it telling everyone you are blind and helpless.
Smooth movement: Cane travel can be more cumbersome and not as fluid. A cane gets stuck in cracks and you get a poke in the stomach, could be painful. The cane gets damaged very often needing replacement every so often.
