EYEGESTURES

EyeGestures is open source eyetracking software/library using native webcams and phone camers for achieving its goal. The aim of library is to bring accessibility of eye-tracking and eye-driven interfaces without requirement of obtaining expensive hardware.

Using EyeGesture Engine V2 - Machine Learning Approach:

from eyeGestures.utils import VideoCapture
from eyeGestures.eyegestures import EyeGestures_v2

# Initialize gesture engine and video capture
gestures = EyeGestures_v2()
cap = VideoCapture(0)  
calibrate = True
screen_width = 500
screen_height= 500

# Process each frame
while True:
  ret, frame = cap.read()
  event, cevent = gestures.step(frame,
    calibrate,
    screen_width,
    screen_height,
    context="my_context")

  if event:
    cursor_x, cursor_y = event.point[0], event.point[1]
    fixation = event.fixation
    # calibration_radius: radius for data collection during calibration

Customize:

You can customize your calibration points/map to fit your solutions. Simple copy snippet below, and place your calibration poitns on x,y planes from 0.0 to 1.0. It will be then automatically scaled to your display.

gestures = EyeGestures_v2()
gestures.uploadCalibrationMap([[0,0],[0,1],[1,0],[1,1]])

V2 is two stage tracker. It runs V1 under the hood but then uses it as feature extractor for V2 machine learning component, and combines both outputs to generate new gaze point. It is possible to control how much V1 affects V2 by:

gestures.setClassicImpact(N) # setting N = 2 is working best for my testing 

This makes that sample obtained from V2 is averaged with N times sample from V1 (same sample copied that many times). In outcome having V2 impacting output in 1/N+1 and V1 N/N+1.

It is also worth to know that you can enable hidden calibration for V1 (same calibration when using only V1, but now it is invisible to user):

gestures.enableCNCalib()

Using EyeGesture Engine V1 - Model-Based Approach:

from eyeGestures.utils import VideoCapture
from eyeGestures.eyegestures import EyeGestures_v1

# Initialize gesture engine with RoI parameters
gestures = EyeGestures_v1()

cap = VideoCapture(0)  
ret, frame = cap.read()
calibrate = True
screen_width = 500
screen_height= 500

# Obtain estimations from camera frames
event, cevent = gestures.estimate(
    frame,
    "main",
    calibrate,  # set calibration - switch to False to stop calibration
    screen_width,
    screen_height,
    0, 0, 0.8, 10
)

if event:
  cursor_x, cursor_y = event.point[0], event.point[1]
  fixation = event.fixation
  # calibration_radius: radius for data collection during calibration

Troubleshooting:

  1. some users report that mediapipe, scikit-learn or opencv is not installing together with eyegestures. To fix it, just install it with pip.
