Abstract
We present the Visual Decision Maker (VDM), an application that gives movie
recommendations to groups of people sitting together. The VDM provides a TV like user
experience: a stream of movie stills flows towards the center of the screen, and users press
buttons on remote controls to vote on the currently selected movie. A collaborative filtering
engine provides recommendations for each user and for the group as a whole based on the votes.
Three principles guided our design of the VDM: shared focus, dynamic pacing, and encouraging
conversations. In this paper we present the results of a four month public installation and a lab
study showing how these design choices affected people’s usage and people’s experience
of the VDM. Our results show that shared focus is important for users to feel that the group’s
tastes are represented in the recommendations.
