Exhibits and Displays. While maps and diagrams can be helpful at exhibitions, some people who are blind find it difficult to conceptualise this information. Braille and really large print maps are heavy to carry and difficult to use when standing. Written orientation material, sent before the meeting, allows advanced planning. During the event, directions can be given over the microphone.
Most exhibits are in large open halls with many booths.
Having straight aisles with 90-degree turns and, if possible, different textured carpet in the aisles and booths can be helpful. Some people who are blind will start at one end of an exhibit hall and work their way across the hall from booth to booth, asking the name of each booth and what is being displayed. Handouts enable the person to take away as much information as possible to review with a reader or scanner. However, having alternate formats at the booth is always appreciated. A verbal description of the display pictures or a loop tape that provides descriptive narration of the content of the booth can be helpful.
