Are these genres ill-suited to sustain other modes of visitor engagement?
The primary genre of this venue is visual in the form physical signage in the form of street signs, building signs and historical markers. While the street signs and building signs work well for guiding a visitor to their location, they do not do much to educate and/or inform the visitor to the history of the building. Historical markers can do that, but as small, sporadic and hard to see, especially if destination orientated.
What other modes of engagement would be desirable for the venue?
Augmented reality can make use of all three of the genres by adding another layer of information, being it picture, text or video. It would allow for even destination-based visitors to access historical knowledge while on the move.
