Graffiti for the Blind

Sometimes important information is conveyed through graffiti - be it which gang’s turf you’re on, a mural urging us to commemorate a fallen homey, or an anguished expression of despair conveyed through a crudely printed obscenity.

What good do any of these urgent messages do if people can’t see them? The blind should have the same access to this information as the sighted and I therefore propose the implementation of Braille plaques adjacent to all visual graffiti bulletins and messages.

In order to alert the visually impaired that a particular notice seeks their attention, a motion detector will be mounted on each plaque. When the sensor is tripped, an announcement will instruct the sightless to proceed to its origin to read the Braille message. Alternatively, the announcement could simply be a moderately loud siren.
