In this paper we present an application build on top of electronic institutions in order to create a remote experimental platform for human and virtual agents. Our software objectives are twofold: (1) provide experiment designers with a tool to design an experiment where human and virtual agents will interact, and, (2) provide experimental subjects with a friendly interface to interact with virtual agents through an electronic institution.
