Dear all,
Here is one of our study that compares Emotiv and a medical device. I hope it will be helpful for investment decision.

Re: Problem with TMSI Refa8 on 64 bits windows 7.
Dear pkindermans,
I am also interested in your problem given that I am using the ANT device with TMSI Refa stuff. Where is it possible to download the driver for 64 bits ?
Thanks a lot,
Duvi

Re: Graphic card (Ogre) and refresh rate in the SSVEP
Ok, thank you for your answer. I tried Openvibe 12 with my new computer and everything is working well except for non integer frequencies. Actually, if I use 60/9=6.666 or 60/7=8.5714 as frequencies (with a refreshing rate of 60 Hz), the flickering is not regular. I mean that for a while, the flicke...

Re: Stimulations to VRPN Server synchronization
Dear all, I am sorry but I didn't see the replies before.. Actually, we are controlling a device in "real time". The problem with VRPN (in the version 9.0 at least) is that when a modification appears at the input of the VRPN server, it sends the new data to the client. The problem with the P300 pip...

Re: SSVEP terminate called without an active exception
I reinstalled Openvibe with the new dependencies and it still does not work. At the end of each script, I have "terminate called without an active exception" Here is the openvibe-ssvep-demorc content: # This file was automatically generated! # If you want to change the SSVEP configuration # please u...

Re: SSVEP terminate called without an active exception
Hi, I've tested all you ask for. Yes, I have only issues with the SSVEP scenarios on openvibe 12 and everything is ok on version 11. My procedure is to run the configuration scenario, which crashes at the end, run the training scenarios, which also crash at the end but provide results. I am using th...

SSVEP terminate called without an active exception
Hi everybody, I have tried the new OpenVibe release (12.0). However, when I launch the different SSVEP script, the system always crashes at the end and provides this message: "terminate called without an active exception" What is the problem ? How can it be solved ? (I work on Linux) Best regards, d...

Re: P300 magic card extension
Thanks ! It works as desired. But, I have still the problem that the background is not black everywhere. Do you have an idea ?

Re: P300 magic card extension
Thank you for your quick response ! Regarding the background, I have already changed this and I obtained something shown in the picture below (on Ubuntu or Windows). Regarding the number of rows, I succeeded in creating a lower number of cards but not a higher one (the script is crashing and there i...

P300 magic card extension
Hi all, For a student project, I need to implement a P300 magic card-like system. However, some of the requirements are not implemented in Openvibe: a dark background and a 5*5 matrix: - Regarding the background, I modified the value in the interface to dark but there is still a small area around th...

Re: Stimulations to VRPN Server synchronization
Thanks all. Actually, I succeeded in using P300 and Button VRPN thanks to a simple trick. the problem was that the pipelines from rows and columns were not synchronized resulting in a non-synchronized reception of button modification at the client. A simple way to solve this is to impose a modificat...

Re: Stimulations to VRPN Server synchronization
Thank you for you response !
However, in my application I can not use the parallel port (not available).
My only possible way to communicate is through VRPN.
There is no box/trick to synchronize two stimulations from different sources ?

Stimulations to VRPN Server synchronization
Hi all,
I am developing a simple P300 scenario with a VRPN client. However, the VRPN server does not receive the stimulation from rows and columns in a synchronized way. This leads to transient response in my VRPN client. Is there any means of circumventing this problem ?
Thanks a lot.

Re: P300 with idle state
Thank you !
I will look first the simplest approach and then, try to integrate a more complex one
