Emotiv Response

I sent a couple questions to Emotiv on the 20th of October to do with the differences between EEG and non-EEG. I also told them a little bit about my app ideas and asked about their Performance Metrics Suite. This is their response. I will try to work around the issues that this presents.

Hello Isabelle,

They have different firmware in the headset. EEG headset will allow the viewing of raw EEG data in our EEG viewer browser app as well as Emotiv’s proprietary metrics (Facial expressions, Performance Matrix, Mental Commands) in our CPanel browser app. It allows researchers to look at data at these specific locations and calculate their own metrics should they desire. Non-EEG headset will show metrics but no raw data. You won’t be able to do research but can still track your cognitive performance and develop apps.

If you want the software to work with OpenVibe, I'd recommend EPOC/EPOC+. 

Insight and EPOC are designed for different purposes. Clearly EPOC has more sensors and therefore measures more regions of the brain, giving a more complex view of mental activity. It is more appropriate for research where information density is critical. Insight is positioned over key brain regions found to be important for our detections but there is less signal redundancy which can be used to reduce the effects of noise in more extreme situations, therefore EPOC retains higher accuracy in more situations. In good operating conditions both headsets perform well in detecting our key emotional outputs. The reduced sensor count also means that distinguishing 3 or more Mental Commands is slightly more difficult and some facial expressions cannot be detected with Insight. 

Or let's say Insight detections have been reworked significantly and are different to EPOC detections. The lower sensor count produces a lower spatial resolution and significantly reduces the available redundancy in the available information. Expressiv has less detections, Affectiv detections are a different list by and large, and Cognitiv self-trains so the detections are similar in principle. The devices are designed for different markets and applications.

But if you still stick to Insight, we have released iOS and Android Insight app.
- This is the link to iOS app: https://itunes.apple.com/us/app/emotiv-insight/id1031805596?l=vi&ls=1&mt=8
- This is the link to Android app: https://play.google.com/store/apps/details?id=com.emotiv.insightapp

Insight app allows you to record sessions and review your performance metrics and Mental Commands app allows you to control a virtual object with your mind.

We thank you for your support and apologize for any inconvenience the delay in responding may have caused. We hope this instance has not tainted your experience with Emotiv and if it has, we hope to continue to work with you to improve your outlook in the future.

Kind regards,
Emy
