End-User Interfaces for Energy Efficiency Information Services
This work investigates how information services can establish energy awareness with the users of a social network like Facebook . Various visualization approaches where explored to give the user the needed insight on his or her usage habits to scale down energy usage in the long run. To collect data about user's interaction with such an information service, an interface for an existing social network was designed and implemented. Users got their energy usage data visualized in different ways and had to react depending on how they interpreted the data. Evaluation concluded that users shown consumption data as a realtime graph and as cost in Euro were more likely to interact with the interface than with other visualization approaches.
