Opensesame and Virtual Reality

ChiaraDL

Hello there everyone,

there is a chance that I might try to design Virtual Reality experiments in a future project and I would like to know your opinions or experience with interfacing Opensesame with the Headsets/Systems available on the market.

Is it (or will it be) possible to use a headset with opensesame to track task responses and/or eye movements?

Which would be the most appropriate headset to consider?

I am now applying for funds, so the questions I have are rather generic... just to make sure that what I am proposing is actually feasible 😅

Thanks in advance for any input!

Hi Chiara,

Disclaimer: I'm in now way experienced with VR experiments.

As far as I know, VR experiments are usually implemented in Unity, which is based on C#. If I read this Package correctly, you can access Unity from within Python. Therefore it should theoretically be possible to use Opensesame to control a VR environment. That being said, it almost certainly will be very challenging and somewhat questionable whether it wouldn't make more sense to go directly into Unity.

Perhaps these papers will help you getting an idea of the logistics of VR studies:

Hope this helps,

Thank you Eduard, sorry for getting back to this only now!

I looked at the papers and the documentation and it makes sense that one would go through Unity directly, thanks!

The problem with these headsets now is that every 6 months there's something completely new on the market and I wonder whether what could be done with the older models can actually be accomplished with the more recent as well...

If anyone using VR environments has useful information on which visor one should buy as of today, that can be controlled in order to collect experimental data, I would really appreciate any insight! 😊
