We have reached out to EMOTIV staff to ask about the calibration problem we were experiencing and learned more about the product features and capabilities. To our surprise, the EmotiveBCI software package is free-to-use and will process common EEG signals for application development. However, the system is closed-source and doesn’t provide reliable ways of tuning, so our team would desire to replace as many EEG signals we would like to capture with our own processing system as possible. As mitigation, with the challenge in obtaining stable data, we planned to integrate EMG as a backup/ add-on feature on top of the EEG data acquisition to allow control signal options.
We have tried switching the electrodes of the device around and test with the API that EMOTIV company has offered and understand what data their platform offers and how we may want to design our own.
We are in the middle of purchasing a license for obtaining EEG data from the device and acquiring a sensor for acquiring EMG data to augment our device with more potential user input capability.
