These problems we observed are typical of the results one obtains when people trained in the visual arts attempt to create informational graphics. Unless they are properly supervised, visual artists have a tendency to sacrifice legibility, accessibility and clarity for visual appeal.
In addition, a misguided attempt to comply with ADA laws may have contributed to the problem.

Because the signs were small and located excessively close to the items on exhibit, people tended to stand directly in front of the sign for extended periods, which often resulted in the blockage of other patron’s view of the item on displayed. A much larger sign located above the item would have been readable by several people simultaneously without blocking anyone’s view of the often small items on display. There is no good reason why an explanatory sign should be unreadable if the viewer is located more than three feet from the sign. Most museum visitors would prefer to be able to easily read the signs comfortably rather than appreciate the resident graphics artist’s subtle, tasteful small signs.

The low vertical position of the signs caused neck strain for taller patrons. Again, larger signs located above the items would have prevented this problem. If the low position is required for ADA compliance, then a second sign should be made available for taller people. Not all disabled people are short or use wheel chairs. For people with back problems an excessively low level sign is inaccessible.

I was aware that a booklet with large print printouts of the signage text was available, but that was an inadequate substitute for well designed signs. Most people did not notice that the booklets were available.

To improve future signage I recommend the following practices:
1. Do not allow a young graphic artist with perfect eyesight to make final signage decisions.
2. Test the signs with people of a variety of sizes, ages and visual acuity to insure that the signs are readable for all.
3. Locate the signs above, or far enough away from, the item being displayed so that a person reading the sign does not block the view of the item.
4. Do not use fonts or backgrounds that impede legibility.
