EEG headset.
The engagement levels will be output as a progress chart detailing the user's
attentiveness towards the material.
Detecting Head and Eye movement to Hall effect sensors will detect the orientation of the wearer's head relative to the
determine engagement with the board.
educational material.
The eye tracking glasses will track the user's eye movement relative to the front
of the board.
Ease of Use The device must track the wearer's engagement without jeopardizing the
wearer's comfort.
The headset must be adjustable to fit most head sizes.
The eye tracking technologies must not obstruct the wearer during use.
The setup and operation times for the device must be no more than 15 minutes
Reliability The device must be sensitive enough to detect all of the different signals in real
time with negligible error.
The data must also be collected and analyzed in a manner which validates the
usefulness of the device.

3.  Narrowed desired signal to only engagement
or disinterest
 Determined if patterns of engagement could
be established and replicated using the
Emotiv EEG headset

4.  Three Patterns:
 Long Term Engagement Stability
 Short Term Disinterest Introduction
 Short Term Engagement Recovery
 Final test for response time between changes
 Utilized video game medium to promote
engagement (similar to Hatch medium)

5.  Conducted in five random tests
 Test ran entire length of long term window

12.  Eye tracking device indicates at which part of
the board the child looking
 Integrated with EEG headset to monitor the
child’s engagement level
EEG and Eye Tracking

14.  Positional Detector Hall effect Sensor
determines the position of Head
 Can detect the direction the wearer is facing
relative to the front of the board

15.  Two types of Hall effect sensor
- Hall Effect switch
- Hall Effect latch
