In order to validate our approach of visualizing and interacting
with sensor and actuator devices by using standard
web technologies we performed some preliminary tests. As
discussed earlier our main enabling technology in this area is
EXI that allows us to compress and process more efficiently
XHTML input and output on embedded nodes with limited
memory and computing capabilities. By using standard web
technologies the human interactions follow a familiar and
intuitive pattern already used in the world wide web and
thus the learning curve for the users is not steep. Moreover,
the use of embedded XHTML/EXI servers on the nodes
eliminates the need of special software installed on the users’
mobile phones - it is sufficient to have an Internet browser.
