  In this report, we present our work in visualization and augmented reality
technologies supporting collaboration in manufacturing automation. Our approach
is based on (i) analysis based on spatial models of automation environments,
(ii) next-generation controllers based on single board computers, (iii) cloud-,
service- and web-based technologies and (iv) an emphasis on experimental
development using real automation equipment. The contribution of this paper is
the documentation of two new demonstrators, one for distributed viewing of 3D
scans of factory environments, and another for real time augmented reality
display of the status of a manufacturing plant, each based on technologies
under development in our lab and in particular applied to a mini-factory.
