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.

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.





 Here you can find the final video explaining Moody concept and all the process of his development

This is our last post,
we hope you enjoyed it


All the best, Environment 1




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.


On Thursday, May, 4th
we conducted our user test; we placed a table near the service point at IO
Faculty and we put Moody on it. We asked participants (people passing by) to
try to interact with the product; we put a graphic card in front of Moody, it provided information about the Moody purpose, a hint of how to
activate it and the meaning of the lights.

After interacting with
prototype, we asked participants to fill in a questionnaire. Results are
presented in following graphics.



User test is presented in following video.

Moody graphic card








In order to run user test we are working hard; we will run it on Wednesday 4th, May.

Our context has changed a little bit; it is not an office anymore but is more a public space like the waiting room in a building. We choose this context because we want to create a greater aware about the CO2 level; an office (our last context) can be a lonely place where only few people could have contact with the product so this is the reason why changed our mind; within our new context more people can interact with Moody.




In following video you can see the prototype that we are going to use for the user test. We built an interactive prototype that is going to be very similar to final one; in the middle of the way, we have found some issues about the interaction, necessary changes will be implemented after testing.

User test will be run in a public space, near the service point at IO faculty.

USERS -ITERATION 4 (Week 3.10)

Our user research will be divided
in 2 phases, the first is to test individual interactions and second one is to
evaluate the whole system with a working prototype, simulated in a realistic

This week Friday, we tested two aspects
with a couple of students at IO: the interaction of moving the hand over the
flower head and the feedback of this action. The paper prototype was used as a
mock-up, but now some blinking lights have been used to test the feedback. The
growing of the flower as feedback was already proven to work in previous user
testing session. Now participants were asked to activate the flower without
further instructions and then blinking lights will show its status of measuring
the CO2.

Following chart shows the kind of
interaction that we have in our design and the kind of feedback that will be
given to the users. We will try to run our user test based on this






In order to catch up the ITD schedule, last Friday (April 15th), we put together the components of our system for the first time!






We made a little movie where you can see the explanation about all the system and how it works.

Next step is to put all components into our "prototype" and run a user test. We still need to discuss how are going to develop it.



As a delivable of ITD course (and to close nutcracking cycle),  we were asked to send two postcards about our design:

*First postcard explains our concept






* The second one is about technology we are planing to use into the prototype and the technical components that we will need to build our interaction








In order to finalize nutcracking cycle, we had a presentation where we showed a video of MOODY.

Enjoy it!

On Friday morning  (April, 7th), we received a feedback from the ITD staff about the video we would present in the afternoon as the end of nutcracking cycle; the main comments were:

-Try to mantain only one "style" (we had animation, slow motion and some to images)

-Music should match with our concept in a better way.

Basically we spent the day making improvements to the video and we talked a little bit about the components of our prototype.

At the end of the day we presented our mock-up paper and our video. We are a little bit worried because we still need to make test about the technological seetings, so next weeks will be harder, we need to catch up!
