response: Yeah, there are tactile warnings that can be used as an alert to visuallu impaired people
original_response: I know, I feel the same way. I wish there were more tactile warning that can be detectable by long canes to alert the visually impaired but some think they might be hazardous.
history: Do you know anyone with visual impairment? I feel so bad for anyone I know who does I do not. Do you know anyone blind ? Those have total or lose to total vision loss I don't. I only know people with visual impairment I see, people who have visual impairment can have difficulties with activities like driving, reading, walking and even socializing That is just so sad to me, I take it for granted every day, I wish there was something I could do to help them...
knowledge: Tactile warnings provide a distinctive surface pattern of truncated domes, cones or bars detectable by long cane or underfoot which are used to alert the visually impaired of approaching streets and hazardous surface or grade changes.
