2.   Interpretation should provide novel, varied experiences and avoid repetition.

Providing variety is important, as humans instinctively pay greater attention to changes in their environment. Repetition quickly loses visitor attention, and without attention, it is difficult to communicate successfully. For example, an organisation may decide on a signature 'look' for their signs and use this at all their attractions. Although this provides continuity, there is a very real risk that visitors won't read the content because they assume it will be similar to those previously encountered.

Repetition and boredom can be reduced by designing exhibits and signs that incorporate:

audiovisual presentations; models; computers simulations/quizzes/games; sliding panels/flaps and other interactive elements; games and tests of skill or knowledge; metaphors and analogies; stories; and hypothetical scenarios/problems to solve.

The focus should be on providing novel, multi-sensory experiences. If possible, these should include an element of fun as this facilitates learning and enhances the likelihood of messages being remembered.
