Gaze Point Heat Map

Easy to use command line based tool to generate a gaze point heat map from a csv file. ๐Ÿ‘๏ธ

Usage

Install the required dependencies from the command line.

pip install -r requirements.txt

This tool was created based on Python 2.7. Make sure you are on that Python version to avoid problems.

Run the script from the command line.

python gazeheatplot.py gaze-data.csv 1440 900 [-a 0.6] [-o output-name] [-b /Me/bg-image.png] [-n 200] [-sd 33]

Data Format

Each line contains at least the X- and Y-values. If you have fixation data and want to take the duration into account you can add it to the end of each row. The data has to be formatted in the CSV format (comma-separated values).

X Y Duration (optional)
123 654 226
134 662 234
... ... ...

Shortcut and Additional Arguments

GENERAL ARGUMENTS:
-h                    --help                                 show help message and exit

REQUIRED ARGUMENTS:
input-path                                                   path to the csv input

display-height                                               an integer representing the display height

OPTIONAL ARGUMENTS:
[-a ALPHA             --alpha ALPHA                          alpha of the gaze overlay                 ]
