Hi Rafael, it seems that there is a bug in our code. If you press 'connect' before having updated the Emotiv path to point to the correct location, it looks like the process will unset the PATH environment variable. For us, a workaround seems to be if you quit the acquisition server, change the emot...

Unfortunately we don't have resources here to support additional platforms (and if we had, Mac would probably be our priority), but to some extent we can answer precise technical questions if someone else takes up this kind of porting task. One thing is worth mentioning -- unless you have all the cr...

If you're trying to compile openvibe on anything else except the supported platforms (e.g. standard pcs running the usual OSes, see supported platforms), you can expect to run into all sorts of problems, and solving them will need you to understand and modify C++ code. About the particular case, if ...

Great, we'll be interested to hear what turns out.

Hi, the start_time and end_time for OV_addOutputBuffer() should specify the interval of the data block in question. The second value in the stim_set is the actual time stamp of the stimulation. You'll need to figure out the exact time your second sample corresponds to. Then, the stim_set time stamp ...

Hello Ed, we've tested the released package on Win7/64bit here, and the examples you mention work ok for us. Its difficult to say what could be the problem, to my eye the log file doesn't seem to have anything unusual. I can only assume there's either something exotic on your system, or that some ot...

Hello ed,

its been clearly mentioned in the supported hardware list that mindwave mobile is NOT supported until 0.16.0 (which is not released yet). You'll have to compile the SVN version or wait.


Best,

Hi,

seems the colours are decided by CSignalDisplayView::onStimulationReceivedCB() function of ovpCSignalDisplayView.cpp and possibly the other nearby functions. I'm afraid you'd have to modify the source and recompile.

Hello DrMick, sorry for the late reply. The Simple 3D Viewer box is bugged at least in 0.15.0, possibly earlier as well, and doesn't work (fixed in SVN 'trunk2', or 0.16.0, out soon). At any rate, it doesn't accept any input, its solely meant as an illustrative coding example how to get (some) 3D vi...

Hi mhardin, many thanks for the suggestions. They had gone a bit under the radar for me, something wrong with my RSS. We'll try to incorporate them soon, not possibly to the next release (which is due this week), but to the SVN at least.

Tick 'show unstable'.

You should specify designer the --play --no-gui parameters that I mentioned earlier.


Happy hacking,
Jussi

We've renamed the scripts around for some extra confusion, but yes, the ov- script is basically the same animal as the corresponding openvibe- script. If you're on Windows, the explorer might hide the .cmd extension.

Its called 'shell scripting', basically on Windows you open the command prompt (write 'cmd' to start menu search box) and write the stuff there while being in a directory with the openvibe-designer.cmd script. After you know the sequence of commands you want, you use a text editor to write them down...

Hello Chris, some very interesting links there. I'm not too familiar with biofeedback, but I think the question about meditation (when narrowed down to the scope of the links you posted) and EEG boils down to two questions, 1) Is gamma activity reliably measurable with consumer grade EEG devices tha...
