CHI 2011 publication: "Into the wild: Challenges and opportunities for field trial methods"

A paper on the nature of field trial methods that I helped write is to be published at CHI 2011.

Brown, B., Reeves, S. and Sherwood, S. Into the wild: Challenges and opportunities for field trial methods. To appear CHI 2011.

Field trials of experimental systems ‘in the wild’ have developed into a standard method within HCI - testing new systems with groups of users in relatively unconstrained settings outside the laboratory. In this paper we discuss methodological challenges in running user trials. Using a ‘trial of trials’ we examined the practices of investigators and participants - documenting ‘demand characteristics’, where users adjust their behaviour to fit the expectations of those running the trial, the interdependence of how trials are run and the result they produce, and how trial results can be dependent on the insights of a subset of trial participants. We develop three strategies that researchers can use to leverage these challenges to run better trials.
