HCI research contributions to the world of knowledge

Here is a fun exercise:

make a list of the knowledge contributions that HCI research has produced over the years.

First some definitions:
Assume that HCI research is about the interaction between humans and interactive computational objects.

The human part is quite straightforward. It refers to any human being, groups, organizations or societies of human beings.

The "computer" part is less clear, but to me, it makes sense to see that as interactive computational objects. Both interactive and computational seem to be part of a general understanding in our field. There are many objects that are not computational but interactive, or the other way around, but we mainly focus on those type of objects that are both. The notion of object is of course complicated. Traditionally it refers to physical machines, but it has changed and can now be any composition and manifestation of functionality that anyone sees as the part a human is interacting with. Ok, these definitions are not enough, but a simple starting point for the exercise.

So, if this is what HCI research is studying with the purpose to understand, explain, reveal, challenge, and improve etc. then what are the major contributions that the field has produced over the years? What do we know about this interaction between humans and interactive computational objects?

Of course, there is a huge pile of knowledge that our field has produced about details when it comes to interfaces, interaction, design and development, technological aspects, etc. But, what if we try to formulate contributions at a very high level of abstraction.

For instance, if the field of HCI is stating that interaction with computational interactive objects is different than interacting with non-computational interactive objects? If so, would that be a major contribution?

It would be exciting to see the field try to formulate some major knowledge contributions that would complement the world of knowledge. Of course, it does not mean that the field would agree on these contributions but at least they would be seen as some kind of substantial knowledge that other fields and the world would benefit from knowing.

Jerker Lundequist "Norm och modell"

[This post will be in Swedish]

Jag sökte en bok idag. I en av mina hyllor hittade jag istället Jerker Lundequists doktorsavhandling från 1982. Titeln är "Norm och modell - samt ytterligare några begrepp inom designteorin". Jag vet inte hur många som har läst Jerkers avhandling, men den var enormt viktig för mig. Jag hade precis startat min doktorandutbildning och sökte förtvilat efter texter kring designteori och kanske ännu mer efter exempel på hur designforskning skulle kunna utföras. Jerkers text och ansats passade mig perfekt. Han arbetar med en filosofisk metod, analytiskt, begreppsanalys, definitioner, etc. något som jag hade troligen sökt men inte tidigare sett.

Jag blev så betagen av Jerkers ideer att jag reste till Stockholm för att träffa honom. Jag var nervös och visste inte riktigt vad jag skulle säga när vi träffades. Men det blev ett bra möte. Han var pratsam och vi diskuterade designteori i ett par timmar på arkitekthögskolan där han jobbade. Jag träffade honom ett flertal gånger senare under årens lopp.

Nu när jag bläddrar i hans avhandling kommer en massa minnen tillbaks och en massa ideer. Det är så tydligt nu hur påverkad jag blev av hans arbete och hur mycket det formade mitt eget tänkande, och fortfarande gör.

Nu när jag läser lite här och där i hans avhnadling blir det tydligt för mig att hans text, ideer och tankar är relevanta än idag. Fler borde läsa honom!

Why designing is not irrational

Any approach that is aimed at changing our reality is an expression of a specific understanding of what it means to be rational, to think and act in a rational way. Most people strive to be rational in some sense, but it is obvious that what it means to be rational varies.

When I look back on my own research over the years, the notion of rationality has always been at the core of my studies. Actually, my Ph.D. dissertation had the title "The Hidden Rationality of Design Work". The core idea of the dissertation was that as long as we can't reveal the hidden rationality of designing, it will stay difficult to describe and understand, and even more important...teach. The study of designing has since then made huge progress in revealing the 'hidden rationality' of design (see Schon, Cross, Krippendorff, etc).

One of the major problems with the notion of rationality is, to me, that people confuse what being rational means with one specific interpretation. This narrow understanding of being rational is highly influenced by what is seen as the highest form of rationality--the scientific process. But most people do recognize that depending on what we are trying to achieve, we need to embrace different forms of reasoning. It is crucial to understand that we have to embrace the notion that rationality comes in many flavors, each bringing certain strengths and weaknesses. If this is not understood, it becomes a problem.

For instance, some people argue that design thinking means not being rational. Some even argue that designers are, or even have to be, irrational in their thinking and doing. This is however only true if we understand 'being rational' in a very narrow sense. 

To argue that designing is irrational is, therefore, a mistake. Designers are rational and have a well-developed rationality (if they are good at what they do). Designing requires both logic and rationality, but it is a logic and rationality that is aimed at exploring and developing new ideas that can lead to not-yet-existing designs. This means that what is rational as a designer is not the same as what is applied by someone involved in trying to explain how reality works or create an understanding of some particular aspect of our reality. Design thinking is aimed at changing reality into something that we do not know what it is,  into something that is only an imagination. Such a process requires certain forms of thinking and acting, it requires a certain form of rationality. The 'hidden' rationality of designing. 

Ok, this is already too long, but as a takeaway idea, I would propose that anyone involved in the study of designing or has ambitions to improve designing spend a bit more time trying to understand the notion of rationality. It is a theoretical tool that is extremely important in any exploration of human approaches of inquiry and action.
