In the paper "A Survey of Augmented Reality" from Azuma he said: "Some researchers define AR in a way that requires the use of Head-Mounted Display". So I'm searching now for the researchers who defined AR in that way, but I found nothing. If anybody know who defined AR only in combination with the use of a See-Through-HMD, please tell me who it was. I need this information for my study.
Thanks a lot
