Product Description Design Specification

Determine engagement with the

educational material by utilizing an

EEG headset.

The EEG headset will be used to determine the user's engagement towards the

material.

The engagement levels will be output as a progress chart detailing the user's

attentiveness towards the material.

Detecting Head and Eye movement to

determine engagement with the

educational material.

Hall effect sensors will detect the orientation of the wearer's head relative to the

board.

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.

Narrowed desired signal to only engagement or disinterest

Determined if patterns of engagement could be established and replicated using the Emotiv EEG headset

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)

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