Synchronize Stimuli-Tool from Unity3D with BCI2000

Post by maschu » 12 Jun 2014, 06:15

Hello guys,

within the scope of my bachelorthesis I want to design a stimuli-tool in Unity3D, which I can use with a BCI-
System.

I have worked through some related informations. But at that moment I am completely confused how to start.

The biggest problem in my head is, how to synchronize the events from my tool with the recorder of BCI2000 (or
another recorder^^). I don´t even know where I have to put my attention to.

Would someone mind to explain to me the main points I have to consider?
I must confess, I am far away from being an expert in networking etc.

Best regards

Mascha

Start by reading about AppConnector. You may also decide that the per-block states that you can get from App Connector are not sufficient and you may want to implement your own custom app connector that includes an asynchronous input logger.

Hello Boulay,
here again thanks for your fast response.

I have already read the documentation of the AppConnector.
But unfortunately it is still not obvious to me, what I have to do.
Is the AppConnector a tool, which I simply can isntall? Or is it an interface, to which I can connect my external tool over UDP or similar?
Or is it a codefragment, which I can use in my Code? I am a little bit confused ... :(
Is there some more detailed information concerning the AppConnector somewhere?

Best regards

Mascha

I think you should go through the BCI2000 tutorial. There may be some steps that are outdated, but the background information it provides will help you understand how on-line processing and feedback of brain signals works in BCI2000. Then you'll be better able to understand how AppConnector fits in.
