Initial Goal
To prepare equipment and sensors for complex data collection (audio, video, physiology, eye and body tracking) during a VR experiment aimed at studying the user’s state while passing a maze under stressful conditions

Our Goal:

  • Real-time data acquisition and visualization of audio, video and physiological signals

Parallel processing and recording of different data streams can be a challenge, especially if the sensors react sensitively and the underlying software is not really stable.

Initial thoughts:

  • Which sensors are we dealing with in the first place?

  • What sensor data do we get?

  • Check the SDK’s / API’s of the sensors

  • Specific Hardware needed?

  • Real time data and Recording?

    • Visualisation

    • Consider delays and losses

    • How to record together in parallel via several connectors?

  • Define architecture

  • …

Plan (ordered in priority):

  • Stable data aquisition without losses

  • Lightweight software for performance and low complexity

  • Real time visualisations for supervising data aquisition during experiment

  • Pipeline for versioning and fast deployments

  • Clean code architecture for further development

One main goal is to be able to use the different sensor software for experiments of all kinds, with little effort to extend features and develop improvements.
