It happens that some ports can be opened even if no Brainmaster device is plugged to them for instance modem and bluetooth devices usually use COM ports as well. Its format is as follows: OpenViBE implements a drift correction process to allow devices without hardware triggers to reliably tag signals during acquisition. Check that your serial number is set correctly Check that your passkey is set correctly Check that you use the passkey you received from Brainmaster for OpenViBE and that you are not using the passkey that should be used for Brainmaster Try with a lower Bds rate.

They bgainmaster include options related to the specific Brainmaster devices. However, if you still want to disable it, process as follows:. The COM port can be autodected. Check that your serial number is set correctly Check that your passkey is set correctly Check that you use the passkey you received from Brainmaster for OpenViBE and that you are not using the passkey that should be used for Brainmaster Brainmxster with a lower Bds rate.
So for that reason and as an option, you can change these settings manually and go ahead with a pre-filtered signal. Finally go to the OpenViBE forum http: As soon as a -big- block of samples gets to OpenViBE, it realizes too many samples were acquired as it adjusted the drift previously so it -again- adjusts the drift in softwafe opposite way, causing the signal to be significantly modified this is the worst scenario happening for the drift correction process!
Its format is as follows: Choosing a preset will select the best settings for the device you want to use.
Then run softwrae tests with the acquisition server and save the openvibe-acquisition-server. This issue can be solved reducing the buffer size and latency of the COM port which the device is connected on.
In order to activate this feature, edit your configuration file and point the appropriate variable to the file you want to dump the stream in.
It happens that some ports can be opened even if no Brainmaster device is plugged to them for instance modem and bluetooth devices usually use COM ports as well.
The raw content of the data stream can be dumped in a text file. During the buffering period, OpenViBE believes the device does not send enough samples and adjusts the drift accordingly.
The driver supports the following models:. The device serial number can be found on a sticker on the back of your device.
This can be checked doing the following actions:. These devices have been supported by OpenViBE since version 0.

In order not to set-up the keys each time you start the acquisition server, you can set the following environment variables to your OpenViBE configuration file:. These options include the common options that you find softwage all OpenViBE drivers subject identifier, subject age and subject gender.
The other four channels are the 4 Auxiliary channels.
Development How to contribute Bugtracker Inria gitlab Build status. This means each EEG channel has a possibly independent reference. Atlantis brainaster use two electrodes per EEG channel.
The other two channels are the 2 Auxiliary channels. Then run the brainmasrer server. In order to reduce the buffer size and latency of the COM port, process as follows:. The device passkey should be requested to Brainmaster support. A1, R1, G, A2, R2. Still hardware filter usually have better performances than software filters.
It is not recommended to disable the drift correction process.
Download this documentation as a PDF file. It is a different key than the one you have for Brainmaster software. Entering the configuration panel of the driver offers a number of options. This results in four channels:
