Commissioner: STIHO


Stiho is a supplier of construction, wood and plate materials. Costumers of Stiho are construction companies active in building, renovation and the development of small new building projects. Craftsmanship and knowledge about product and application modes are disappearing rapidly in the Dutch construction industry. Ageing is the main reason for this development. The loss of knowledge and skills is already causing problems in maintaining the quality of project in this industry. The question is how these skills and knowledge can be preserved and circulated to future generations through digital storytelling? The target group that Stiho wants to reach consists of construction companies active in building, renovation and the development of small new building projects. The media application that has to be developed must make this knowledge accessible to craftsmen at the ‘Stiho-building square’ (together with the Giebels formula) and at building locations.

Collecting feedback

This week we started to develop our first user-tests. We created these tests to get a better idea of whether our concept suits the end-users’ needs and expectations. Via the user tests we can find out what the users really think and how they act when working with our prototype.

Paper Prototype

A paper prototype is a quick and easy way to experiment with different elements and functions. You can easily cut out parts of the prototype and replace them with a different piece. It is fast, easy and efficient prototyping. We started with converting the functional concept into sketches. We got our inspiration from already existing apps like Voxer, WhatsApp and DigiSocial. We used this as an input for our prototype to understand how each feature relates to another.  We then ran through the whole prototype a few times, took pictures of each image and put them into Protosketch.


With protosketch it’s possible to bring your sketches to life and make them interactive. For example you can make a button drawn on paper clickable and link this to another sketch. The idea is that we are using a real smartphone with our sketches on it for the user-test.

Our toys

When conducting the user-tests we are going to use very interesting and fun gadgets. We have a webcam that can be mounted on your smart phone. It films whatever you do on your app and can even see the finger movements capturing the ease and difficulties faced by the user when navigating. The second is a pair of glasses with an inbuilt camera. We can use these to test our app on site.


Next Monday we are going to do a pre-test with some colleagues from the MediaLAB. On Wednesday we will visit Haarlem where we are going to conduct our real user test with two contractors. Also part of this user test is card sorting. Card sorting is a technique in which users without design experience make a category tree. They structure data in logical clusters and categories which we can use as an input for our information structure.
