On November 27, 2012, FTW hosted event “Research Highlights Energy”, where SESAME-S presented its final outcomes together with other concluding energy projects at FTW, such as GreenHome, KOFLA, MeloNet.
Check out our 2 SESAME-S presentations, one about the project in general at Slideshare:
and the school use case specific at Prezi:
In cooperation with eSYS, FH Hagenberg and FTW, the BBS Kirchdorf was provided with several hardware and software services that measure and control the power consumption of computer rooms. In particular, Smart Meters were installed in three computer rooms and on hallways of the school which measure the overall power consumption of the computers and the light installation. Combined with a power management service from eSYS, this creates an opportunity to optimize the power consumption by remotely shutting down or suspending idle computers.
An Android based mobile client was implemented to provide a graphical user interface for the power management service. With this client all functionality provided by the service can easily be used to potentially reduce energy consumption. The software can be installed on any Android powered smart phone and is designed to be used without any prior knowledge about Android – so everyone should be able to use it. The design of the application is shown in the figure below.
Further research will explore how such a power management service can be used efficiently in a school context.
Smart meters are pervasive and complex devices. And although the usability and convenience of smart metering devices have improved significantly over the past few years, configuring and using them appropriately demands a lot of effort from the user. Handling such devices efficiently in terms of learning effort, energy efficiency gains and joy is crucial to the broad acceptance and success of smart metering in individual homes and among lay users.
In volume no. 9 of the PsychNology Journal (9/1, 2011, p. 55 – 72) Kerrigan et al. have presented the results of a user survey that investigates into acceptance barriers of smart metering devices among lay users. According to their research the following aspects are crucial for creating acceptance of smart metering technology among this user group:
- the familiarity of the terminology to the user; lay consumers are not expected to know symbols (such as “[!]” top signal that the meter is working properly ), codes (such as “t2” for the price rate type) or jargon (such as “instantaneous power”)
- the adequacy of the information to the users’ needs; for instance, users need to get two values and do a subtraction in order to know the consumption in the current billing period.
- the availability of a back button, since running through 24 clicks in order to see the last information, and having to go though the full series of clicks in order to see it again if by mistake one presses the button once more is not a usable design.
- the perceptual visibility of the information on the display; this can be improved by avoiding that the meter is positioned in an inaccessible point on the wall, and by increasing the lightening of the display or using a back lightened display;
- the reduction of superfluous information, since a small display forces to several steps in order to get a long or complex information. A case in point is the sentence “For information about the contract and notifications of failures please call (a telephone number) ” is divided into 6 chunks, each one requiring a click in order to progress to the next chunk. In case the meters model can still be chosen and is not already installed at the consumers’ households, then models with larger displays should be preferred.
FTW is a nationally leading and internationally acclaimed center for
research and development of technologies for future communication systems.
As a part of a research project on energy-efficient semantically-enabled
smart home systems (SESAME: http://sesame.ftw.at) we are looking for
test users to carry out the user tests. The aim of the user test is to
verify the appropriateness of the system’s user interface for everyday
use by non-expert users.
Your task is to use the system’s interface to accomplish several tasks,
while providing feedback on the clarity, simplicity and
straightforwardness, as well as other aspects of the system regarding
the given tasks.
User tests will last about 2 hours. When you arrive, please report to
the FTW reception desk on the 3rd floor of the Tech Gate building before
the start of your time slot, and the receptionist will direct you to us.
Available time slots are:
Thu., October 28th 2010 – 9:00, 11:00, 13:00, 15:00, 17:00
Fri., October 29th 2010 – 9:00, 11:00, 13:00, 15:00, 17:00
Tue., November 2nd 2010 – 9:00, 11:00, 13:00, 15:00, 17:00
Wed., November 3rd 2010 – 9:00, 11:00, 13:00, 15:00, 17:00
Thu., November 4th 2010 – 9:00, 11:00, 13:00, 15:00, 17:00
As a compensation for the time spent you will receive a 20 Euro voucher
for a shop of your choice: Saturn, Amazon or Douglas.
Sufficient knowledge of English language is mandatory, as well as that
you ARE NOT an expert in any ICT field.
If you are willing to participate, please register for an appointment
with us through an e-mail at email@example.com. We would also ask
you to specify which slots are suitable for you, so you can be scheduled
accordingly, as well as the name of the store you would like to receive
the voucher from.

SESAME Home implements several functions for Home Automation Network (HAN) monitoring and management. It is intended to be used for monitoring sensor values, environment, energy consumption and device availability. Also it is used for setting desired states for controlled locations and creating and re-planning device plans. The following screenshots give you an impression of the Sesame interface. We deliberatelly tried to make the GUI as intuitive as possible following the look and feel of contemporary touch screen designs.
Fig. 1 shows various functionalities of the Sesame system. The buttons at the bottom enable the user to choose from various locations either inside or outside the household. In this special case the user chose the „Environmental“ button to retrieve information about the weather from YahooWeather as forecast provider. Read more of this article »
