Ocumen I/O for Unity - Quick Start

The quick start project allows you to design VR experiments in Unity with just a few clicks, get recordings for Ocumen Studio and process your data with Ocumen I/O for Python.

The quick start scene allows you to run experiments with just a few clicks.

Getting Started

  1. Unzip your bundle
  2. Open the project in Unity, we recommend 2020.3.2
    • You may need to Lock Input to Game View from Window > Analysis > Input Debugger
  3. For some head sets you may need to perform steps outlined in the hardware specific setup before continuing:
  4. Open the main scene under Scenes
  5. If your device is an Android platform, build and run the application. If running on a desktop headset, click “Run”.

This will run the scene and record, out of the box:

  • Headset Pose Recorder
  • Advanced Eye Tracking Recorder
  • Frame Data Recorder
  • Collider Recorder
  • Mesh Recorder
  • Controller Recorder
  • Rendered Video (Alpha)

In addition we integrated Unity’s XR Interaction Toolkit and enabled:

  • Locomotion
  • Object Grabbing

Access Recordings

After play mode exits, your recordings will be in in the application’s persistent data path:

  • On Windows that is %userprofile%\AppData\LocalLow\Tobii\Ocumen Recording Sample
  • On Android, under /storage/emulated/0/Android/data/com.tobii.recording_sample/files/

From here you can:

Whatever you run in the scene can easily be replayed with Ocumen Studio and Ocumen I/O for Python.

Doing your own Science

The steps above just outlined how to get started. However, the scene was made to be easily adjustable. To do so, merely change objects below the Your Experiment object:

You can remove or change anything under the “Your Experiment” node. You can, for example:

  • Add a supermarket scene for shopper research
  • Add and script game-like elements for interaction research
  • Add simple stimuli and adjust scene lighting for basic perception research
