Understanding Public Evaluation: Quantifying Experimenter Intervention

論文アブストラクト:Public evaluations are popular because some research questions can only be answered by turning "to the wild." Different approaches place experimenters in different roles during deployment, which has implications for the kinds of data that can be collected and the potential bias introduced by the experimenter. This paper expands our understanding of how experimenter roles impact public evaluations and provides an empirical basis to consider different evaluation approaches. We completed an evaluation of a playful gesture-controlled display not to understand interaction at the display but to compare different evaluation approaches. The conditions placed the experimenter in three roles, steward observer, overt observer, and covert observer, to measure the effect of experimenter presence and analyse the strengths and weaknesses of each approach.

日本語のまとめ:

公共の場での実験の際に実験者の存在が与える影響を調査した.相互作用できるディスプレイを道路に設置した結果,実験者が被験者に見える位置で見守っていると相互作用の探索の妨げになっていた.
