Mouse cursor control using 3D head pose estimation
Blaž Kovačič · 2023
We developed a method of computer mouse cursor control based on 3D head pose estimation using a web camera image stream.This method can be especially applicable in the field of Assistive Technology interfaces for disabled persons.Our approach stands out by enabling direct conversion of head pose into an absolute position of the mouse cursor, the stability of which was achieved using a special approach of facial key-point filtering.In order to estimate head pose rotation angles we made use of the iterative version of the Perspective-n-Point algorithm together with a seven-point (symmetric) 3D head model, that adjusts itself to the head shape based on facial landmark positions in the starting head position.We demonstrate the effectiveness of our approach using practical comparative measurements.
