designing systems that direct human action
In this paper we present a user-centered design process for Active Capture systems. These systems bring together techniques from human-human direction practice, multimedia signal processing, and human-computer interaction to form computational systems that automatically analyze and direct human action. The interdependence between the design of multimedia signal parsers and the user interaction script presents a unique challenge in the design process. We have developed an iterative user-centered design process for Active Capture systems that incorporates bodystorming, wizard-of-oz user studies, iterative parser design, and traditional user studies, based on our experience designing a portrait camera system that works with the user to record her name and take her picture. Based on our experiences, we lay out a set of recommendations for future tools to support such a design process.
