This is a kind of evolution. There has been...with the arrival of computers in the 1980s, we saw many museums experimenting with the new technologies.
My idea on this subject is that all these communication devices you have, your iPhone or whatever, cannot replace the basis of the three-dimensional objects or heritage that the museum or the heritage site can provide. In other words, they should target something that museums have to offer, but in a complementary way. They should be inviting people to come to see those things rather than giving them all the information.
When I plan an exhibition, I always say that there are three levels of reading in an exhibition. The first level is either the works of art or the titles of the major text. Then the secondary text is more informative, and the third level, which is usually hidden, is one that you have to find in other ways, because it's not readily available, and that kindles food for thought.
I think this is where we can come in with this museology of ideas that I was talking about and put in the ideas, because the museum does not have ideas. It collects mostly 3-D objects, but these ideas are linked to these objects, and people sometimes do not see the relationship. This is where this third level of reading is important, and the new technologies help museums in providing that to the public.
It's not an easy task.
