Looking past yesterday's tomorrow: using futures studies methods to extend the research horizon

Doing research is, in part, an act of foresight. Even though it is not explicit in many projects, we especially value research that is still relevant five, ten or more years after it is completed. However, published research in the field of interactive computing (and technology research in general) often lacks evidence of systematic thinking about the long-term impacts of current trends. For example, trends on an exponential curve change much more rapidly than intuition predicts. As a result, research may accidentally emphasize near-term thinking. When thinking about the future is approached systematically, we can critically examine multiple potential futures, expand the set of externalities under consideration, and address both negative and positive forecasts of the future. The field of Futures Studies provides methods that can support analysis of long-term trends, support the identification of new research areas and guide design and evaluation. We survey methods for futuristic thinking and discuss their relationship to Human Computer Interaction. Using the sustainability domain an example, we present a case study of a Futures Studies approach - the Delphi Method. We show how Futures Studies can be incorporated into Human Computer Interaction and highlight future work such as rethinking the role of externalities in the validation process.
