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.

`The Happy End`-Movie

And-this is the last post from toolkit group.We hope you enjoyed with following our works during the semester.

Last words are from our movie and here is the link:

‘The Happy End’ – Photos


Lastly, the photos from our prototype:



last times and the exhibition day


Yes, the last couple of weeks were the most tiring stressfull and busy weeks. We were dealing with the last minute problems,finalizing the prototype,visuals to explain our concept, blogging to keep you updated,report to tell our whole process..

Here you see some snapshots from those moments that we feel a bit (!) freaked out 🙂



And finally- the exhibition day we set up a  ‘mysterious’ exhibition space to call people come and explore the world of electronics…




It was a fantastic atmosphere to walk around all the studios and enter a different context each time and try out different prototypes with enjoyable concepts… 

In the end of the day, we were tired but happy and satisfied with all the reactions we got from the guests…It was nice experience to share our 5 months effort with the people… And more importantly, to see them playing with the toolkit with a curiosity and smile on their face…



e-xplorer interface

We have been explaining about the hardware part of our project but we also have an interface.
With the e-xplorer interface, users get feedback about the components thet select, upload the projects
and see the diagrams of the project that they want to build. 
This interface is an important part for our design but we kept the design so simple,this way it is only the
supportive element for the interaction between user and the hardware part.
Here some screen shots from the interface, It shows the process of how to use e-xplorer toolkit step by step:


Now, time to talk about the last couple of weeks, finalization of the project, preparation for the exhibition
and finally -the exhibition day!
Stay tuned!
Toolkit (only one) 🙂


Hey all!
Now time to talk about the story of the pieces of our prototype and our fablab trip as I mentioned in the last post.
When we went there, firstly we chose the materials, upload the files to the laser cut machine.
Here you see the process step by step :
-waiting for pieces to be laser cut…..(for your info: 30 euros per hour and it was a bit slow!! 
 -the pieces are in!


  -extracting the pieces… it looks cool, right 🙂
-now, let`s have fun!
 After that we started integrate the electronic components in them and fix the pieces together: 
-the scanner tool with the rfid reader in it…
 -the components without the electronic stuff in them..
 Next time, max5 nand the interface!

Keep tuned :D

More about magnifying glass

  Hey all,

 We wanted to show how we made the last model of magnifying glass.To be able to test it quickly, we decided to use wizard of oz method and programmed the color changes of led with Arduino.





Now it is ready for a final test.
Next time: Protoype and Fablab
Stay tuned! 😀

Final tests before prototyping


 Yes, `the e-cooker` evolved to `the e-xplorer`!!
As you remember the main elements of our toolkit are electronic components(blocks),an arduino component,
an RFID scanner and an interface(on laptop). Previously, we used the`bowl` metaphor to integrate the RFID scanner 
and to make components be defined by max5 programme. For the last couple weeks we have been facing with some usability
and technology problems with the bowl idea. According to our discusions after the 1st user study,we decided to turn the bowl scanner into a more interactive hand tool(a magnifier glass),which allows you to `explore` the components, also the level of the Arduino projects.
The process was a little tough until coming up with the magnifying glass idea.We made a lot of sketches and also brainstorming.  

After deciding on the magnifying glass idea, first step was making a mock up model of the tool. As you see in the image below
you can select the difficulty level of the projects manually by turning the dial from `green` to`yellow` or to `red`.You can also first select the difficulty level and then scanthe components. The colored parts are supposed to be made by LEDs in the real one.

Of course we needed to test it to observe its interaction with the user:


 However we decided to test it with the actual interactive features one more time.
This way we will revise all the weak points before starting to prototype:


Now, we want to test the latest version of interface and scanning tool together.
 Next time, you ll find the latest news about the components and Arduino projects,
stay tuned! 😀

The progress in final prototype plan

After we wrote down the final prototype plan last week, we specified the key points that we have to finalize as quickly as possible.
The most important ones are:
  • How many projects we want to include to the system and which components that we want to use for them?
This is the list of projects we have right now:


  • Stealing alarm àlight sensor, piezo element (easy) àProximity alarm (opposite)
  • Adjustable alarm (speed or volume)à potentiometer, light sensor,piezo element (basic)
  • Robot scared of light àtwo LEDs, light sensor (eyes close)àtwo LEDs, light sensor, servo motor (head turns away)
  • Clap light on àLED, piezo element (easy) àAdjustable clap light on, with potentiometer (basic)
The list of components:


 In progress…

 Now we are working on the complete diagram of the projects starting from the beginning ( select-scan components) and showing  also the possibilities of `tinkering` part.

We ll keep you updated during the week! 




About the user test and the results


In our user study, we observed how bachelor students are interacting with thetoolkit as well as learning their expectations when they want to learn aboutelectronics and Arduino.



Since target users are bachelor students, we made our study in IO Building.


The participants had experience with using Arduino before. 
We gave a quick explanation about the project and asked them to make a project by using one input and output.
The instructions given are:
1-Choose the components by scanning 
2- Choose the project from interface
3-Make the project with Arduino as you see from the feedback on the computer screen.



In the end we made an interview an asked some question about the experience in detail.
Here are some conclusions from the interviews:


  • The interaction with the components is easy and clear forthe participants.
  • The components and the feedback simply shows how to make aproject but does not show the programming part. However, there is an Arduino coursein Bachelor that teaches programming with Arduino.
  • When the LED light blinks faster as the potentiometer isbeing turned the next step should be to learn `why and how` does the LED blink.this can be done by showing the programming part.
  • Using the blocks as electronic components makes the experienceeasier and faster. But at some point it can stay at an abstract level. 

The sub-clinic session

In the meeting with Aadjan and Walter, we came up with theresult that we need to specify some tinkering projects that help user to makeand experience more creative projects. So we are going to include some `suggestion`to provide user more freedom while making different projects.



…Best Wishes From, TOOLKIT-1
