In this second workshop on Wearable Systems for Industrial Augmented Reality Applications we will discuss the following topics, related to wearable computing and AR technologies: core technologies, such as hardware, AR development kits or AR-enabled software; software architectures and applications concepts; as well as business ideas and case studies of AR systems within the industrial context. Furthermore, with upcoming consumer wearables, such as Google Glass, we will compare requirements for such consumer-grade systems with requirements for systems designed for users in industrial environments. Some of the key questions will be: How much AR do we need? And how much AR can we stand? The second workshop on wearable systems for industrial augmented realtiy applications will take place in conjunction with Ubicomp 2013 and ISWC 2013 in Zurich, Switzerland on September, 9th 2013.
