Tsvi Kuflik and Antonio Krüger organize from August 30th - September 3rd a German-Israeli Minerva School for Ubiquitous Display Environments: Intelligent Group Interaction, Foundations and Implementation of Pervasive Multimodal Interfaces. I will teach a session on: "Embedded interaction with display environments" and here is the list of recommended readings for the participants - if you are short on time only read the first one and glance over the other two.
