Augmented Reality (AR) as defined by Azuma  does not pose restrictions on
output devices to be used for AR. Starting with light-weight notebooks and ultra
mobile PCs, recently smartphones became favorite AR output devices. They represent
a class of self contained computing units, providing (usually limited) computing
power as well as input and output peripherals - all in one device.
In contrast to that are output devices without a general computing processing unit
which rely on external source to create and transfer image data. The latter are of
interest in this work.
In this chapter we present wireless technologies that can be used to transmit uncompressed
stereoscopic video signals to wireless displays in real time. We introduce
two output devices, a stereoscopic head mounted display (HMD) and a TFT
display module. Both of them have been adapted to act as wireless receivers in order
to display wirelessly streamed AR content. Next we focus on advantages of
wireless displays for educational AR applications. By way of example two educational
AR applications are presented which were used to demonstrate and test
wireless displays. A number of teaching scenarios are described where teachers
and students greatly benefit from the use of wireless displays. We briefly summarize
the results of our observations while developing and evaluating these displays.
