The Goal:An Open and low cost
solution forEEG monitoring in
Pediatric ICU
EEG reading: the challenge
EEG reading: what is it?
EEG reading: almost clear
Clear! But ... the meaning???
Professional Setup
Consumer Setup
+
Professional vs. ConsumerQuality/Cost
Professional ConsumerApplication
Professional YES Work in progress
Consumer WHY? YES
Project Overview: the Goal• Where: Pediatric ICU• Usage: Continuous bedside EEG monitoring• Requests:
– Medical validation– Available for each patient– Low cost– Easy to use
Project Overview: the final setup• EEG:
– dry sensor technology– Setup easy and confortable
• User Interface– Usable by nurse and even relatives– Inspired to ASG (Augmentative Serious Game)
theory
Current choices• EEG:
– Emotiv Epoc
• User Interface– Linux PC or Android tablet
+
A feasibility test• EEG acquisition device: Emotiv Epoc• Preelaboration: Linux box• TCP/IP communication channel to
– OpenVibe– Matlab– Android– …
• Elaboration• The question is: can Emotiv record evoked potential?
Acquisition device• Emotiv Epoc
– Dry sensors, wireless connection– HID (Human Interface Device) standard
communication protocol– Packet encrypted (AES)– Raw data stream available via SDK– Independent/unofficial projects (EmoKit) exists on
the web to decode the realtime stream
Preprocess• Realtime acquisition box: a box used to acquire
realtime data and send to the desired application for analysis or other:– a linux box (HID is supported in default kernel)– data decoding – Open a TCP/IP socket for data streaming to
the application
Process• When data are available, can be sent to
specific software …– OpenVive (to test EEG elaboration algorithms) – MatLab (with the EEGlab suite)– Quick and dirty Python tests :-)– Android specific app
… to OpenVibe
Emotiv data acquired and visualized with OpenVibe
… to EEGlab
Data imported to EEGlab, with Oddball paradigm events
Oddball paradigm in Python
2 seconds acquisition around a rare event (sample 128): a P300 evoked potential?
Conclusion• We can setup a measure chain from data to elaboration• With consumer devices and open source or commercial tools• For details: http://www.giammy.com/files/bci.pdf
• Can Emotiv record a P300 evoked potential? • Ready to pass on to neurological signal elaboration experts!
