This is the community wiki for the Naturalistic Experimental Design Environment, or NEDE. 

NEDE (pronounced "Neddy") is a scripting suite designed at Columbia University to leverage the capabilities of the Unity3D game engine into the neuroscientific study of realistic scenarios. Unity is one of the most widely used 3D game engines - its extensive documentation and user forums make it relatively easy to pick up, and its flexible scripting abilities make it highly customizable. NEDE adds a series of scripts designed to provide the features that neuroscience experiments require: randomized stimuli, precise timing, and peripheral hardware. NEDE's capabilities include:
  • Real-time interface with a research-grade eye tracker
  • Synchronization with research-grade EEG systems
  • Randomization of custom stimuli (images/objects) and their positions
  • Runtime GUI to let experimenter change experimental settings
  • Frame-by-frame recording of camera position for analysis
  • Replay capability superimposing eye position on the subject's original view
A paper detailing NEDE's capabilities has been accepted to the Journal of Neuroscience Methods and can be seen here. If you use NEDE in your research, be sure to cite the paper:
