Lisa worked with professional Braillist(s) who used grade-one Braille, so (she felt) the work could be easily understood by a wider audience. This Braille is written letter by letter, so even a sighted person could download the Braille alphabet off the computer and stumble through the descriptions of the photographs. The Braille accompanying ‘tactile mind’ is in (American) English, which is the standard for North America.
The Braille describes the photograph – how it is cropped, the mask, if the subject is turned to the side, etc. Generally when a blind reader ‘sees’ a tactile diagram of a person, the diagram is head to feet, facing forward. The Braille description given in ‘tactile mind’ helps guide the reader through the photographs for a better understanding.
