Summary: Utility of Human-Computer Interactions:
Toward a Science of Preference Measurement
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.
