Comprehensive and modern German book on HCI by Bernhard Preim and Raimund Dachselt

After having read an electronics preprint some weeks ago Bernhard and Raimund showed me the first printed version of their book "Interaktive Systeme 1: Grundlagen, Graphical User Interfaces, Informationsvisualisierung, Mobile Interaktion" (amazon, springer). The new edition brings a comprehensive overview of human computer interaction with many illustrations and examples. It is perfectly suited for teaching.

Congratulation to finishing it! I am always amazed how people manage to create these books without locking themselves away from the world for a year…
