This paper introduces a new theory to understand perceptions of technology, the Theory of Sociotechnical Representations (TSR). This theory is developed by bringing together Sociotechnical Systems Theory, a well-known theory in IS literature and Social Representation Theory, a theory from social psychology. TSR explains that while people and technology interact and influence each other, people create representations of technology, which may differ across individuals and/or groups. It further alludes to the fact that interactions or influences between people and technology as explained by SST may actually be between people and their representations of technology. As such, this theory explains that understanding representations of technological phenomena play a critical role in the way technologies are understood and used.
