The following are design guidelines for designing visitor-facing museum technologies and tools, synthesized from the collective wisdom of the museum professionals we've interacted with.

1. Technology shouldn't have the spotlight--technology should support and encourage the museum experience, not be the experience.

The museum experience is about the artifacts and stories behind the artifacts. If the visitor spends more time looking at their mobile device, etc. than with the artifacts, then the museum has failed.

2. The technology should be subtle enough that it doesn't get in the way of natural interactions.

Social interactions, conversations, etc. are part of what make the museum experience visceral. Technologies that demand the visitor's undivided, uninterrupted attention take away from that (e.g., headsets limit interaction with other visitors).
