Summary and contributions
We have seen, that there were some approaches to eliminate the Watt indicator from energy measurement devices.
What never have been addressed is the question whether
these different approaches truly lead to more awareness
of energy consumption, in contrast to conventional energy
measuring devices using Watt or kWh as an indicator. In
this work I argued, that a large scale user study to address
this question of awareness would have been hard with the
prototypes introduced in those works that ipresent an alternative visualization. From this argumentation, some
properties for prototypes used during large scale user studies are discovered. When a prototype encompasses these
properties, it will be more suited to conduct a large scale
user study with it. In this work I have proposed a prototype, that tries to encompass these properties. The main
idea was, to combine PowerSocket [Heller and Borchers,
2011], an appliance level measuring device, with the EM773
smartmeter in a device from Ikea, seen in figure 3.1. In this
work only a prototype is introduced that tests the functionality of this design, with exception from the energy measurement circuit, which is not functional during the time of
