  2. questions on MindAffect cVEP BCI

    by YuminosukeSato · June 2022
    I was trying to use the mindaffect bci application, but I can't run it and get an error. So, is there any other application that can acquire brain waves with ssvep or p300? Brain waves are taken by

    There are many posts here on the Forum and on Google on the "flashing light stimulation" modalities of BCI. These are called SSVEP, steady state visual evoked potentials. And cVEP, code-base

    cVEP of MindAffect is far superior to SSVEP based BCI.

    Is it possible to classify brain waves by command only by brain waves such as moving the drone forward without using P300 or SSVEP? If possible, I'm currently using openBCI, cyton 16ch. Is there any g

    VEP Visual Evoked Potentials, such as cVEP and SSVEP, which allow the user to place attention on an area of the screen that is 'flashing' at a certain rate. The measured visual response in the brain

    have shown, certain EEG / BCI paradigms, such as SSVEP, cVEP, P300, will benefit from wet electrodes, because the signal to noise ratio can use all the help it can get. For example with the MindAffec

     If you are not in ideal conditions, you might get a little more noise and then you might have to adjust the SSVEP parameters, like maybe increasing the duration of acquisition before identifying the

    but when I run my experiment, I can not see the SSVEPs (but I am pretty sure that there must be SSVEPs because when I use the gel cap for the same experiment I see them). So, I don't know what's goin

    julienConscious
    by julienConscious · December 2021
    it is possible to use dry electrodes for SSVEP. Hard to tell what's wrong here: the most common issue is that the hardware parameters are not correctly applied, as @retiutut mentioned it is sometimes

    Over on the other recent thread link below, @lucasbaldezzari remarks that he can use his SSVEP BCI acceptably with his gel based (wet) cap system. But when he uses DRY electrodes (either passive dry,

    We had a similar issue when generating an SSVEP Stimulus inside a Widget, since when setting a certain frequency of stimulation, the period corresponding to that frequency wasn't accomplished on every

    I am assuming I may have to do additional preprocessing steps to better be able to infer the SSVEP frequency from the plots?

    I had the limit of 200 Hz on the X axis, as I thought this may help to identify the SSVEP frequency because of the harmonics that may show? But okay I changed it:

    If you're trying to do this manually it would help to lower the X axis limit to 50Hz or 75Hz. Next, it would be best to know what the SSVEP frequency being used was, rather than having us (and maybe y

    I am currently working with EEG data acquired during an SSVEP experiment. I am still relatively new to the BCI domain, so I do not have a lot of experience yet. I am trying to determine what frequency
