An interface to run Wizard of Oz experiments with voice-based virtual assistants. The application is based on Meteor framework.

You might find this app useful, if you are running Wizard of Oz experiments with voice interfaces. The app is based on the Meteor framework. The interface has two web pages: agent and wizard.

The Wizard page contains candidate answers you might want to use, they need to be figured out beforehand to make the interaction quick. However, there is also a text field that can be used in emergencies, if you need to deliver an answer, that is not on the soundboard.

The Agent page only has a visual interface: a ball that changes color and size depending on wether the system state at the moment. There are 3 states: inactive, actively listening and speaking. After reading an answer, the system stays active for 5 seconds and then automatically switches to inactive, unless the Wizard explicitly changes the state.

The state is maintained through a MongoDB record, that is updated by the Meteor functionality in realtime. All events are also logged to other tables. Python script dbdump.py will dump out the logs from those tables into a local json file.

To get the application up and running, you should create a new Meteor app, and install all dependencies.
