2.  Completed First Immersion
 Scheduled Hatch/Smart Board Installation
and Training Sessions
 Continued Correspondence with SMI for Eye
Tracking/EEG Software
 Assessed Thermal Camera Technology
 Created and Evaluated a Prototype of Hall
Effect Sensor Technology
 Created and Evaluated a Prototype of Low
Powered Laser Tracking Technology

3.  Conducted at the Early Childhood Education
Center (ECEC) associated with Louisiana Tech
University
 Observed children using the Hatch education
software on a Polyvision board
 Specifically observed how students and
teachers interacted with the software and
board

4.  Installation and training sessions scheduled
for February 27-28, 2013
 Board will be installed on a stand provided by
a third party company in the Biomedical
Engineering Building at Louisiana Tech
University

5.  Continued correspondence to determine the
usability of our Emotiv Epoc Headset with
the SMI eye tracking software and hardware

6.  Conducted cursory investigation into the
usability of thermal cameras to track
engagement
 Determined to be ineffective
 Slow response time
 Slow rate of change between thermal signatures
of target

9. Video of Hall Effect Sensor Test

10.  Prototype demonstrates the feasibility of hall
effect sensors for incorporation into the
device
 Improvements to be made may include :
 Linear Hall Effect Sensors
 Grid Network Design
 Stronger Magnets

11.  Tracks user’s head
movement
 Uses two lasers, an 8-
megapixelcamera, and
programming in
Matlab
 Isolates laser points on
image Bishestha approximating the head
 Determines where the orientation of the two lasers during
testing
user is looking

12.  Test image taken with
two laser points
included
Laser Points

13.  Image converted to
grey scale in Matlab
 Image is defined in
terms of white
intensity
 Laser points remain
most intense areas
Laser Points

14.  Laser points isolated
on image
 Pixels under threshold
reduced to black
 Pixels over threshold
remain
Laser Points

15.  Determined the
coordinates of
remaining points
 Center point
coordinates found by
averaging these values
 Created a single center
point and reduced laser
points to black
Center Point

16.  Added center point to
original image
 Removed original laser
points
Center Point

17.  Next step is introduction of infrared lasers to
limit device distraction towards users
 Tests prove technological feasibility for
inclusion into overall design
