Today I went to Moma to see an exhibition and also to make some field study. It's was bit crowd and maybe because it was a Sunday most of the visitors were in groups: friends, family.
One of the problems that I see in this project is how to know which artwork the visitor is seeing in order to create a relation btw artwork - emotional state. My first though was in using RFID : every artwork is identified by a RFID tag and the in the device wear by the visitor there is a RFID reader. This solution has a problem: the range of RFID is to small and the visitor has to "read" the tag on which artwork.
In the visit to the museum, I noticed one interesting thing that I didn't remember before: most of the people( not all) reads the legend card that identifies every artwork. I don't know if I can interpret this as a sign that the visitor wants more information about the piece.
If in every legend card/board there is a rfid tag or an infra red that connects with the visitor devices, then the problem have a solution. I also start enjoying the idea of having the visitor manifesting his desire of being tracked by a certain artwork and not with all. The physical gesture can also be interesting in terms of interaction.
