The Incidental User

Sunday, February 1, 2009

Welcome!

There's something that's been on my mind for a while...

During the 10 years before I started studying toward my PhD, I did over 100 projects that involved designing user interface for software and systems. One project in particular - Lumenis One - got me (and my partner, now also my wife) thinking about what we could do to not only make the system easy for the doctor to operate, but simultaneously make the treatment more pleasant for the patient. Although, in the past, there had been projects in which I planned, say, a bright red alarm in the top right of the screen so the supervisor could see it over the operator's shoulder, this was the first time I really considered someone who was very definitely an interested party, but wouldn't actually be using the system.

As part of the design process, we visited clinics and watched doctors perform treatments. We noted the distance between the bed and the device, the lighting conditions and angle. We interviewed a doctor and patient about what the main fears are when having such a treatment and we worked to design screens that made the patients feel confident that their treatment was exactly as it should be, in addition, of course, to supporting the needs of the doctors.


As time went on, I noticed more and more cases of this passive type of interaction with systems - the checkout at the supermarket, the yearly auto inspection, visits to the doctor, etc. It seemed as if all these systems could offer more if they could somehow take people like me, who weren't actively using the system, into consideration.

At the CHI conference last year, I started to discuss this with Noam Tractinsky, one of my advisors, and we started to further develop the idea, describing the phenomenon and determining its place, as part of the Services Science field. We threw around various names and finally settled on "the incidental user" as being the most appropriate.

We're now at the point where we feel we've adequately defined the phenomenon and are taking steps to define its various aspects. Noam and I welcome any examples you may have and any questions on the topic.
