Producing knowledge by design for design

The field of design, particularly the philosophy and theory of design, is evolving fast today. Over the last thirty years there has been a plethora of writings about the relation between science/research and design. One of the most contested questions has been to what extent design as a process of inquiry and action also is a legitimate process of knowledge production. It is not strange that the question arises. Science and design have distinct and different purposes as approaches. Jonas Löwgren says it clearly in his recent ACM Interactions article when he writes "The essence of research is to produce knowledge, and the essence of design is to produce artifacts." This is a clean and simple distinction, even though we know it is possible to find examples that makes this definition more complex, but Löwgren states that even if there are other purposes involved in research today, "the knowledge-production purpose is primary".

The same can be said about design of course. Design can have many different purposes but at the core it is all about the process of imagination and production of artifacts (systems, symbols, services, etc), or with other words, it is all about changing reality. Even though the discourse around design as a valid form of knowledge production approach has grown, it is not until lately that we are seeing some real advances. Unfortunately, a lot of energy has been devoted to develop definitions that are compliant with the existing understanding of knowledge production as it is practiced within the scientific tradition.  This has led to an outsider perspective on design, that is, design is seen through the scientific definitions, understandings and concepts of knowledge and method. Less energy has been devoted to start from within, with the ambition to develop an insider perspective--a perspective that takes it starting point in a real and deep understanding of design as its own tradition and not seen as "not science".

I made the argument in my article "The nature of design practice and implications for design research" (ref below) that one of the common mistakes done when it comes to design theory is to use an outsider perspective (particularly with a stance in science).  Anyway, it is clear to me that we are entering a more productive stage in the development of design philosophy when the insider approach is becoming more common. For instance, the article in ACM Interactions by Bill Gavers and John Bowers on "Annotated Portfolios" and Löwgren article mentioned above are great examples of this emerging realization that design has a real role to play in knowledge production and that the formulation of what that role is has to be done from within design grounded in a deep understanding of design. 

A new understanding of design as a knowledge producing approach can be established  but not by trying to make design into something it is not. This means that the road forward is not to make or force design to become more scientific or to use scientific methods, instead it means that we have to acknowledge and externalize what the core strength of design is. This is what Gaver, Bowers and Löwgren is doing so well. Löwgren states this well in his article when he concludes:

"To conclude, I strongly support Gaver and Bowers in claiming that design practice has a place in HCI research today, and that the researcher can add knowledge value by providing annotations in addition to the artifacts. My own contribution here is to recognize the proposal for annotated portfolios as an intermediate-level knowledge practice among other such practices. To me, those practices appear to be promising paths toward fruitful academic discourse and collaborative knowledge production that accommodates the nature of design practice without undue “scientistic” reduction."

This is exactly the way forward. However, this is also a challenge of magnitude since it requires anyone who engages with this issue to be equally well prepared in the philosophy of science as well as in the philosophy of design. Even if we are making progress, there are still few who have the ability to make thoughtful contributions based on such double competence, but with a new generation of thinkers who see it as natural to be equally competent in science and design there is hope.

Löwgren has a great list of references in his article. To me, these selected references are examples of this new and growing understanding of design as research. I am pleased to see my own writings among the ones I selected :-)

Searching for definitions of "interactivity"

I have for a while been working on a paper about the notion of interactivity. It has been great fun but also quite challenging. First of all, doing some search of literature it is clear that even though interactivity is a core concept in my field of human-computer interaction  few have tried to define it carefully. I have started my examination by using a simple definition from the Merriam-Webster dictionary. In the dictionary two definitions are mentioned:
“ 1. mutually or reciprocally active, and 
2: involving the actions or input of a user; especially: of, relating to, or being a two-way electronic communication system (as a telephone, cable television, or a computer) that involves a user's orders (as for information or merchandise) or responses (as to a poll)”

This is a fairly good definition but for the purpose of HCI is can be developed in many ways, and that is what I am trying to do. For instance, it is clear to me that the notion of agency needs to be included, maybe also the concept of predictability. Anyway, at the moment I am trying to find already existing definitions. If you have any suggestions of well developed definitions of interactivity, please let me know.

ACM Interactions again

It is exciting to see the number of invited bloggers on the ACM Interactions web site. This week, new blog posts by Jonathan Bean, Joe Sokohl, Elizabeth Churchill, Jeffrey Bardzell and Phoenix Perry! Discover new voices from the industry and follow up on the researchers you know! The combination of the printed magazine with its articles and the blog with shorter and moer personal reflections is great. I also think we have been able to find a great group of researchers and practitioners in the field to write blog posts. They have all agreed to write for Interactions on a regular basis so we are expecting the flow of good posts to continue. Please go there, read and get involved in the discussions.

ACM Interactions magazine

I have now, together with Ron Wakkary, been co-Editors-in-Chief of the ACM Interactions magazine for about two years. It has been a great experience. Reading the submissions is great fun. I have read more about our field than ever before and especially texts about topics I would never have read otherwise. I have also had the chance to work with a large number of wonderful researchers and practitioners in our field. Personally I also think that Ron and I have been fairly successful in developing the magazine in a direction that I find exciting. People may not know this but the number of submissions is growing and the acceptance rate is going down, and today it is way lower than 50 %.

Anyway, the new web site is doing well and now we have added a blog section to which we have been able to recruit a number of really interesting people in the field. We have about 25 researchers and practitioners who on a regular basis will blog. You can take a look at the first blogs already. We hope that this blog will develop into an important part of the magazine and also lead to real debate.

Unfortunately the number of members of ACM SIGCHI who is the owner of the magazine is going down. This is not good since the field as such is growing and so is the CHI conference. So, please if you are not a member of ACM SIGCHI, become one. To be a member of SIGCHI is possible without being a member of ACM so it is not even expensive. You also get a discount at the CHI conference and you get the Interactions magazine sent home to you!
