De meningen ge-uit door medewerkers en studenten van de TU Delft en de commentaren die zijn gegeven reflecteren niet perse de mening(en) van de TU Delft. De TU Delft is dan ook niet verantwoordelijk voor de inhoud van hetgeen op de TU Delft weblogs zichtbaar is. Wel vindt de TU Delft het belangrijk - en ook waarde toevoegend - dat medewerkers en studenten op deze, door de TU Delft gefaciliteerde, omgeving hun mening kunnen geven.

Conclusions & Recommendations

The first conclusion is that this prototype forms a good platform for
the further development of the E-Daemon. With the time given we have
build a working prototype using a temperature sensor and mind flex
detetcting brain activity. The programme for the heart beat has been
written but the integration with the other parts took too much time.
Furthermore the two systems, the brainactivity and the servo motors vs.
the temperature sensor and colored LED’s, are not yet integrated. 

the science fair we were given a good suggestion. The E-Daemon could be
used in a private surrounding but also in a professional athmosphere.
Next to psychiatric institutions the E-Daeom could be used for
coma-patients. With this instrument different moods can be indicated
providing more information about the patients state of mind.

For the future the E-Daemon can be improved by:

  • Adding more sensors
  • Visualisation of the mood more apparant in the ferrofluid
  • Integrating the sensors in an easy-to-use product
  • Integrating the programmes in one
  • Making the sensors and E-Daemon wireless


The following schematics have been used for the electric systems.

The codes have been uploaded to the file exchange.


Presentation at Science Fair



The central piece of the presentation is the (semi)working model. Any volunteer can try on the sensors and make the daemon react. Next to the model there is a poster with a schematic of the system and a render. Furthermore there is a flyer providing supplement information about the displayed moods. Finally there is a user manual advising people how to test the model.

Graphic visualisation

For the science fair a poster, flyer and user manual have been designed.

The poster displayes a render of the final product and a schematic of the design. The flyer is used to provide additional information about the moods displayed by the E-Daemon. Finally the user manual helps the user how to turn on the E-Daemon. 

Decide which emotions to use, the characteristics and their visualization

For the next step it has been decided which emotions wille be searched for, how these can be measured by the sensors we have and how these can be displayed in the daemon.

Acknowledged Emotions

Emotions vs. Feelings 

Emotions are the complex
psychophysiological experiences of an individual’s state of mind. Feelings, or
secondary emotions, come from experiencing these basic emotions.
