Desktop walk through


Within a service design workshop (encompassed within the Global Service Jam event) one of the groups used this technique to show a service for adults bored of their daily routine. This consisted of a platform where after choosing a number of tastes you were put in contact with strangers (with your same interests) and suggested a series of shared activities.



By making the concept visual, and more specifically, how the service worked in this mini scenario with our user in question, helped the original group of the idea to have a more real feedback with the people to whom they showed the idea.

This real scenario helps them to visualize quickly and be able to communicate in a deeper way how the service works in a given context.It is a very good co-creation tool, since everyone can palpate and see the solution, everyone can “play” with the scenario and see possible solutions.

Ex: how could you explain a new queue management service at a theme park?

“Take a blueprint and draw the plants of the hypothetical attractions, then place your characters and everyone “go play” to see what happens when that person is in a queue, or when you have to wait for your children to end their attraction. And if you don’t like what you see, what solutions you could bring, all explained in the game board “


Think prototype

think prototype

A prototype can help you think when an idea is way too abstract. And, the best way to think is to build something up. Our project “Droum”*, made with the collaboration of is a very good example.

The concept wasn’t developed yet and we didn’t know exactly what to do. We only knew that our idea should be linked with music. Based on our investigations with experimental artists, there was a demand of creating an object for these artists:

“The most performative object in music is the guitar; everyone can play airguitar when they listen to one. Electronic musicians like us only have buttons to press and it is very unlikely that the audience tries to mimic us”

 The main challenge was to build something without having any visual reference. For this reason, we starting putting objects together, to think with our hands to see if the shape we were looking for could appear.




This technique allowed us to give shape to a very abstract idea. Once we knew its appearance, expert s could join our conversations to help us realize whether our proposal was feasible or not.

*(Concept explanation): A tool that through a devise can help measuring the density of the materials. Based on the composition of the object, “Droum” plays a sound. The piece has a row of vents that work as a wind instrument. People can interact and play their own musical compositions.






Co creation


We made a series of co-creations for the development of new Apps for vision impaired people with the team of Raylight. After the research stage but before starting our creation process, we focused on a series of challenges that our users required.

The first session of co-creation was with people from the company and also from outside it that knew the issues of vision impaired people. During this session, concepts were set up so that they could be worked out with real users afterwards.



The co-creation helped us thinking from a not so technical perspective, because the team was too involved with the problem. We needed, sort of say, people with a “virgin” point of view from our challenges. The concepts that came out from these very first workshops were later moved to co-creation with real users.

The process of creation can be defined in this case as:

  • Co-creation with external people + internal people + defined challenges in the investigation (creation of concepts)
  • Co-creation with end user + the ideas of the first phase (concept definition).




Idea selection


Our challenge was to offer several proposals for applications focused on vision impaired people. After many interviews and user analysis, we proceeded to create ideas.

Although many ideas came up, we finally chose the one that convinced the most team members: “Sound Color”.

The idea answered a very powerful insight we discovered during the exploration: vision impaired people have no style at all; we tend to wear what other people buy for us. Probably I dress like my father, because my mother is the one that helps me. So, it is difficult to me to hook up with somebody!”

Our value proposal consisted in an application that could read the colors. It emitted a higher or lower sound based on the color. The combination of sounds is what helped our user to be more autonomous to decide the chromatic style.



The idea selection tool allowed the group to focus on a particular problem. We feel this technique is good because in case the main idea does not work at the end, the discarded ideas are still available to work over them again.
