Measuring utility of human-computer interaction

Human Computation, along with much of the Internet, only works when humans find tasks fun, enjoyable, or valuable enough to outweigh the time and effort they require to complete. The more value, or utility, that a task and interface provides, the more "work" humans will do. However, we do not yet know how to objectively measure the fun, enjoyment, or value of a user interface applied to a particular task. This demonstration presents the utiliscope, a system that empirically measures the utility of a user interface for a task by putting multiple versions of a user interface together with a task on Mechanical Turk and measuring the amount of money required to convince humans to use them.
