The success of a computer system depends upon a user choosing it, but the field of Human-Computer Interaction has little ability to predict this user choice. We present a new method that measures user choice, and quantifies it as a measure of utility. Our method has two core features. First, it introduces an economic definition of utility, one that we can operationalize through economic experiments. Second, we employ a novel method of crowdsourcing that enables the collection of thousands of economic judgments from real users.
