Today it is widely admitted that a dialogue between experts and concerned users/citizens is needed in order to achieve a good process and
thereby to get a satisfactory result.
Saddek RehalChalmers University of Technology
Every human is a bearer of knowledge.
Architects and designers are more and more aware of the importance of the
users’ knowledge.

What is design?
• to develop pre-conceptions of something not yet existing• to act in a situation ’before facts’• language is necessary as an instrument to express and communicate the
pre/conceptions• the pre/conceptions are communicated through different media• when pre/conceptions are communicated a dialogue is at hand• in the dialogue, pre/conceptions are created by the participants together• Design is not one man’s business
Design is a form of dialogue

The different modes of existence of the artifact along the process of design
Saddek RehalChalmers University of Technology
Verbal expressions.
Diffuse concepts expressed by the
client/users
Perception affection.
Percepts and affects
Conceptualization
Inner representation
Stage 1, in mind
Graphical representa-tions
Interpretation by the designer of the concepts
formulated by the client
Stage 2, through representation
Stage 3, through realization
ArtefactRealization
Stage 4
The artifact can be seen as a language in constant construction during the process. This construction is an act of design.

The phenomena of seeing• We don’t see really. We see as (Wittgenstein). • We perceive things and recognize them as house,
stairs, chairs ,tables, cars etc, because we already have and master the concepts ”house” , “chair”, “stairs, car”etc.
”We should see a dead animal on our plate if we didn’t had the concept beefsteak” (Ramirez)
• We see as in a fanciful manner. One can see a triangle as an arrow, or a tent, or a mountain etc.

Communication: bridging experiences
“If a lion could talk we shouldn’t understand it”(Wittgenstein).

The language stands often on the way for us when we communicate.

The worst is that sometime we seem understanding each other when in reality we don’t

The verbal language
Saddek RehalChalmers University of Technology
The language is an amalgam of different language games developed in different praxis (professional, cultural, social etc...).
The concept is what permits us to see and to conceive the reality in which we live.
We don't see things as they appear to us, rather we interpret them by means of concepts that we already have. Our modes of representation are colored by our identity, (socially, culturally, professionally etc...).
We tend more easily to look for solution to our problems in the limit of what we already know.
What is discussed in the beginning of a design process by the participants doesn't yet exist and is to be constructed. This situation is characterized by the absence of concrete references and the lack of suitable language.
In conclusion, it can be said that the design process in the early stages is a construction of a suitable language by all the participants (users/citizens, experts etc.). This language is the embryo that gives birth to the final artifact.

Deconstruction of the concept”bad air”
Saddek RehalChalmers University of Technology
The concept “bad air”, formulated verbally by participants to describe their work environment, was understood by the interviewer as the “bad quality of the physical air” in the building. When the participants was asked to show pictures that illustrate what they mean by bad air, they chose pictures that show what bad air is not. They explained that, bad air is the absence of openness, feeling the seasons, the weather and the colors of nature. It is what they are missing in their workplace.

Construction of the concept”positive chaos”
Saddek RehalChalmers University of Technology
The concept “positive chaos”, was introduced after a long discussion between participants with different professions on the subject of education. The concepts teaching and learning was first discussed (picture to the left). The participants came to the agreement that creativity is also an important ingredient in education, they found a picture (picture to the right) to illustrate that character and call it “positive chaos”.

Different conceptions of one and the same phenomena
Saddek RehalChalmers University of Technology
When people with limited knowledge and awareness on each others’ experiences meet, it occurs – because of “the home blindness” – communication barriers between them.

“…it is the fact that multimedia can give visual impression… an impression of experiencing, so to say, which can not be done normally…” (Pelle)

”… I think that we use too many words in our culture. Words can hamper communication, ….. reduce the entirety. There is an understanding that lies on another plan between people, and also inside oneself, which I think can be pictured…“(Angelo).

”Here we can say that we approach the borderland….. The image is here to show the breadth and the dimensions of the human need of communication. If we only focus the uses of media, then we must be aware that we reduce communication and impoverish it….” (Angelo).

• ”… but it has to do with surfing away, going out, communicating over the world…. And it is, in a way, a feeling that has to do with multimedia: to control in order to convey something, or to move out in the world….” (Claude).

One possible reason is that he has no experience of casseroles
But, he could easily perceive what a literate adult cannot perceive immediately (the crying baby)
Why?
He recognised a baby and could see it laughing. But, he didn’t recognise the casserole as the adult does immediately.
Why?
The possible reason is that he cannot read and this ignorancemakes him free to hold the book in any direction.
