3D Head Tracking and Gesture Recognition using an 8-by-8 Array of Infrared Sensors

Human head tracking and gesture recognition are both known problems with solutions using RGB-cameras or an infrared emitter/receiver setup.
In this thesis, we propose a method for head tracking and gesture detection using an 8-by-8 infrared sensor array. 
For this, a novel time-of-flight infrared sensor array is employed, which is both financially and computationally inexpensive, while also alleviating privacy concerns due to the very low resolution of the array.
