Re: How to trigger sound event based on eeg?

Hello,

you can use the Sign Change Detector combined with the DSP to get the threshold box functionality. After that simply connect the Sound Player box to it.

Re: Connecting Actichamp with OpenVibe for Motor imagery

Hello, this could be a problem with the scale. Could you try to remove the non-connected channels from the display? You can do this either by using a channel selector box prior to the display or by configuring the signal display box and removing the unused channels from the list of channels. Regards...

Re: Mitsar 201 with OpenViBE?

Hello Russell,

not having the device or the SDK there is not much we can do here. Would it be possible for you to find somebody having the device and the means to write the driver for openvibe? We would gladly include it in our distribution after that.

Re: How to send messages to the console?

Hello Pedro, an easy way to display arbitrary messages would be to use the Lua stimulator box. Add an input to it via right click menu and use it with a simple script such as this: function initialize(box) end function uninitialize(box) end function process(box) while true do if (box:get_stimulation...

Re: Sending data from an external application

Hello rubai,

in order to use the VRPN connection class you will have to link your application to the vrpn.lib library. The library is located inside dependencies/vrpn/lib folder.

Cheers

Re: Sign Change Detector

Hello hydrocity, what are you trying to achieve in your scenario? The sign change detector is one of the boxes which can trigger a stimulation. There are of course the classifiers, python and matlab boxes for general purposes. You can also send periodic stimulations with time stimulator. Cheers Jozef
