EDIA

A Unity XR Toolbox for research

EDIA provides you with a set of modules (Unity packages) to facilitate the design and conduction of experimental research in XR.

Countdown to launch 🚀

Key features

  • Structure your experiment

    Define the information for your experiment at the granularity level which you need: from sessions to blocks to trials to single steps within trials. EDIA builds upon and extends the functionalities of the UXF — Unity Experiment Framework (Brookes et al., 2020) package.

    Getting started

  • Manage it with config files

    Use human readable config files to provide and change central information for your experiment without needing to recompile or touch your Unity code.

    Overview

  • Unified eye tracking integration

    EDIA provides an integration of eye tracking for multiple different headsets (HTC Vive, Varjo, Meta Quest Pro, Pico), managing the parsing of the eye tracker output for you in the original sampling rate, and providing it via a standardized interface.

    EDIA Eye module

  • Remotely control mobile XR experiments

    Control experiments which run on a mobile XR headset (e.g., Meta Quest) externally and stream what the participant is seeing.

    EDIA RCAS

  • Automatically log relevant data

    Use pre-configured tools to log different kinds of data: behavior and movements of the participant, experimental variables, eye tracking data, ...

    Getting started

  • Synchronize with external data

    Use the LabStreamingLayer protocol to synchronize your experiment with other data streams (e.g., EEG, fNIRS, ...).

    EDIA LSL

  • The 🖤 heart of the EDIA toolbox.
  • Structure your experiment: Sessions <> Blocks <> Trials <> Trial Steps
  • Use logically nested Config files (JSON) to manage the compiled experiment.
  • Send messages to the XR user.
  • Experimenter interface.

  1. Use the LabStreamingLayer protocol to synchronize your data.
  2. The EDIA LSL module is a convenience wrapper and extension of the LSL4Unity package.
  3. It provides prefabs and scripts which allow you to
    1. Send precisely timed triggers with a single command.
    2. Easily stream data (eye tracking data, movement data) in world or local coordinates.

  1. Remote Control And Streaming.
  2. Interface with your experiment which runs on a mobile headset.
  3. Load Config files from another device.
  4. Send commands to proceed in the experiment.
  5. Stream the headset view to the experimenter's device (*limited).

  • Central 👁 eye tracking package of the EDIA toolbox.
  • Provides a unified interface for accessing eye tracking data.
  • Example visualizations of eye tracking data: gaze, eye openness, ...
  • Interface for logging eye tracking data via EDIA LSL or writing it to disc.

Separate submodules (packages) allow to parse the eye tracking data from the respective device into the unified EDIA eye tracking structure.
Supported headsets:

Meta Quest Pro

HTC Vive Pro Eye

Varjo Aero

PICO 4 Enterprise
