About my blog

The aim of the ITD course (ID4220) at the Delft University of Technology is to provide Design For Interaction Master students with in-depth theoretical and practical interaction design knowledge to help develop future products based on user-product social interaction. ITD proceeds through a sequence of iterations focusing on various aspects of the brief and the design, and culminates in an experiential prototype.

This blog is managed by Walter A. Aprile: please write if you have questions.



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.

Week 20 – Exhibition and Process

Week 19 & 20 – Product Presentation


Wednesday, June, 29th,
was finally the day for the ITD exhibition.


Since Moody is planned
to be a gift for TU Delft lectures, we believe that people can take them to
their office and share him with their colleagues while awaking the awareness of
CO2 in a friendly way; one potential context for Moody is a coffee corner/
relaxation area in a design studio (since IO lecturers work in that kind of
environment); we transformed studio 10 at IO in our “design


In the exhibition we
had lots of smiles, people really was surprised with the growing of Moody and
the vibrating bee; they asked some questions about the CO2-after all, they
started to be more conscious about CO2 levels.




Here the poster that we placed outside our studio





The brochures that showed the growing of Moody in an interactive way.





And some environmental
tips that were placed alongside Moody to increase people awarness.

This is our last post,
we hope you enjoyed it


All the best, Environment 1



Week 17 & 18 – Vacuum shaping

Factories, smoke machines, grass, and an alien planet

The Exhibition Plan

The narration we want our exhibition to
convey is Dzorb’s life story: from leaving its alien planet and landing in Delft, to working
together with the IDE faculty to raise awareness of the amount of CO2 in the

Important is that we reach not only the person
who interacts with Dzorb itself, but also the audience and passers-by: Dzorb is
only a small creature that prefers one-on-one contact.

Furthermore, our exhibition should reflect
our mission of making people more aware of the bad influence of high levels of
CO2 in a personal, involving way, and complement the final presentation video
and vice versa.


Some of our initial ideas:

Alien planet hanging from the ceiling

Cardboard factories + smoke machine


Fluorescent paint

Glow-in-the-dark stars

Human powered exhibition (metropolis style)
both electric and mechanical




We want to split our part of the studio in two parts: one reflecting a high amount of CO2 with (cardboard) factories and (paper) smoke, and one with grass and plants for good air quality. In the middle will be an area to interact with Dzorb. The main issue is: how can we show the
working of the CO2 sensor in an open environment? How can we create an area
with significantly more, or less, CO2?
To involve the audience more, as fitting our design goal, some features of the factories will be human-powered, for example to provide energy for the lighting of our posters, or to make a story board move. This could simply be by spinning a wheel, but also by riding a bike with a dynamo.
The following floor plan shows more information about sight lines, level of attention for different parts of the exhibition, and walking space.
1. Dzorb’s crater: main point of attention = spotlight. The rectangle around the crater is the space people can use to experience Dzorb’s interaction qualities: a path between an industrial environment with a high CO2 level, and a green environment with a low CO2 level.
2. Cardboard factories with informative posters and space for our brochures. These should we well-lit, as they will be the main source of information for the people who won’t get a chance to interact with Dzorb.
3. Human-powered factories with additional information. This information is not essential to understand our concept, but will help to involve the audience in our exhibition, and provide the people who are interested with more detail. The light will mainly be on the human-power-generating devices, to motivate people to use them, and to make the detailed information visible themselves.
Finally, a sketch of an elevation (front) to show the differences in the heights of the factories, to get a diorama effect:





Friday, 10th of June, was the
day for Prototyping! We have almost all the components together. We want to finish
the prototype as soon as possible so we can be focused on others thing to do…
report, poster, brochure, video, scenario for the exposition….. Lots of thing
to do!!!










 After analyzing results and the reaction of
the people during the test, some changes need to be done in order to improve
the interaction with our Moody.



One result during user test was that
people did not have a clear idea of what kind of action they needed to perform in
order to activate Moody beside the blue light as an indicator of the growing was
not as visible as we thought. As a solution to these problems, we are going to
focus the attention into the sensor that is used to provoke the growing. The
final solution will be the incorporation of a unique element that can be easily
recognizable at first sight; this new element will be a vibrating bee. Bees have
a direct relationship with flowers but people do not want to touch them, we are
going to invert that feeling with the incorporation of a cute and funny bee
that will attract the attention and  invite
people to touch it only a little bit.

The petals shape will be changed for flower
and the connection with the central ball will be done by springs. The design
will have more petals in comparison with the user test prototype; we want people
easily recognize that Moody is a plant.

The speed for the growing of the stem will
be adjusted to have a more natural sensation of the growing of a plant and not
a mechanical antenna.

Week 15 & 16 – Prototype in progress

Experiments with Dragon Skin





Act 1 – Twilight

  1. The staff of the IDE faculty in Delft is in a tense discussion (think Hollywood disaster movie presidential meeting): CO2 problems, mad scientists, alien invasions… Something needs to happen about people’s awareness of high levels of CO2 in the air around them and the problems it causes, not only regarding climate change, but also their personal health. Eventually, a decision is made: the infamous Team Tiger Blood is asked to find a solution.


Act 2 – New Moon

  1. In the mean time… Dzorb is happy with his girlfriend Dzorbina on planet Dzorbius. Their planet has a precarious balance of air quality, and thus all Dzorbs are very sensitive to CO2, and show their agitation with a fast, vibrating heartbeat.
  2. But then, the Mad Bad Scientist has discovered these creatures as a crucial tool for world domination, so he demolishes their planet and sucks Dzorb to his hidden laboratory somewhere on earth.
  3. However, Dzorb is spotted by a mysterious stranger, who gets curious about this little being, and secretly follows him to the lab.


Act 3 – Eclipse

  1. In the lab, the Mad Bad Scientist performs vivisection on Dzorb, discovering all components and technical details (its Arduino brain, its vibrator heart, and of course its CO2 sensitivity) while looking for the clue he needs to fulfill his evil schemes, unaware that the mysterious stranger is watching him.
  2. The mysterious stranger notifies the heroes of Team Tiger Blood of this atrocious act, and Team Tiger Blood realizes that not only can they save an innocent creature, but also solve the IDE faculty’s CO2 awareness issue.
  3. Our favourite heroes come to the rescue, and defeat the Mad Bad Scientist with their magical Dragon Skin® 20.


Act 4 – Breaking Dawn

  1. Dzorb is left in the care of a VIP, who save the world from CO2 unawareness together, by acting out the two different scenarios: high amount of CO2 and low amount of CO2.
  2. Also, they get to know each other, and discover each other’s serendipitous features: a satisfied purring when stroked, and an angry growl when shaken.
  3. They love each other, are aware (and make others aware) of CO2 problems, and live happily ever after. The only question remains: who is the mysterious stranger? Is he one of the good guys? Is he a villain? Is he an alter ego of Team Tiger Blood?
