- Kiosk should at minimum provide two options for printout: high contrast, and "standard" (using 18 point font at minimum).
General design considerations of printed material:
- color is not be the only way of delivering information (helps people with certain kinds of color blindness);
- achieve high contrast between foreground and background colors
- use an easy-to-read font (sans-serif typefaces tend to be more readable and legible)
- font size should be between 12 and 18 pt.
- leading (space between lines of text and should be at least 25 to 30 per cent of the point size.)
- spacing between letters shouldn't be crowded
- a matte or non-glossy finish on the paper cuts down on glare when reading
Large print format
The kiosk has the option to print out this format. Above design considerations can apply but -
- at least a 16-18 point type for maximum readability & legibility
- sans-serif typeface preferably
The kiosk has the option to print out this format on the fly.
Rationale for alternative formats
- Visitors want choice / options for the theme they want to explore. Once a theme is picked, the question for the visitor becomes how to get where they want to go. Thus, the kiosk provides a map. When a visitor arrives at the gallery, they receive interpretation about the themed tour on the gallery walls.
Tactile map annotated w/ Braille
- this provides visitors with spatial and possibly limited interpretive information
- The kiosk doesn't have the option to print out this format but visitors can pick one up at the information desk.
Audio version of themed tour
- this provides interpretive content analogous to what would be found on the gallery walls
- rationale: not safe to assume most blind people read Braille. Allows people to more independantly access the interpretive content for a theme.
- provided via mobile or loaner device (kiosk should inform of this)
