“After more than 10 years of Mobile HCI, providing an overview of the state of the art becomes more and more challenging. During the tutorial days of Mobile HCI 2008 & 2009, a number of well-known researchers in Mobile HCI gave overviews of the state of the art and cover many of the relevant topics. The tutorials also introduced the must read papers in this domain. The audience varied and included new students starting a PhD in Mobile HCI, practitioners wanting a quick survey of the state of the art and educators wishing to get an overview of Mobile HCI for their own teaching.” (Enrico Rukzio) – courtesy of Wolf Noeding
