Timeline Manual

Presentation

Timeline is a visual editor that runs on top of Playmaker for Unity3D.

It is the editor used to create experiments for the eVRS project.

The timeline editor allows to create and run Complex VR experiments using Unity, RTX and a bunch of different external Hardware including CyberGlove, Vicon Tracker, VRPN peripherals and Arrington Research EyeTracker.

The authoring can be done on any computer with Unity3D (Free/Pro) and Playmaker Installed.

The execution will only work on Pro if you use any external Hardware, and on a dedicated SpaceApplications Platform If you need precision and trueness (ISO 5725) such as EEG experiments.

Editor Features

On top of Playmaker features, the Timeline editor supports Linear editing which is more adapted to Precise Neuroscientific experiments generation. With the editor you can:

• • Create Tracks on GameObjects and Manage them

  • Quickly Add Actions to a Track, in a linear fashion and tweak parameters

  • Manage Events and Variables

  • Save / Load Tracks and Timelines to Readable Files

  • Copy / Paste Multiple Actions

  • Send Signals to external Hardware for Marker Synchronization

Hardware Integration

Currently, eVRS experiments can be run using :

• • Occulus - Rift : Head Mounted Display

  • Sencis - Zsight : Head Mounted Display

  • Arrington Research - PC 60: Head Mounted EyeTrackers

  • SMI - Red 250: Desktop EyeTracker

  • Vicon - Bonita / Vicon Tracker VRPN : Full body Motion Capture

  • ANT - WaveGuard / Amplifier : EEG Parallel Amplifier

  • CyberTouch - CyberGlove : CyberGlove

  • Keyboard / Mouse / Joystick / Serial button box
