Query: Eavesdropping on Electronic Guidebooks: Observing Learning Resources in
  Shared Listening Environments   We describe an electronic guidebook, Sotto Voce, that enables visitors to
share audio information by eavesdropping on each other's guidebook activity. We
have conducted three studies of visitors using electronic guidebooks in a
historic house: one study with open air audio played through speakers and two
studies with eavesdropped audio. An analysis of visitor interaction in these
studies suggests that eavesdropped audio provides more social and interactive
learning resources than open air audio played through speakers.
