## Introduction

**GazeFollower** is a powerful and easy-to-use gaze tracking system designed specifically for use with web cameras. It
offers an intuitive Python API, allowing developers and researchers to integrate gaze tracking into their projects with
minimal setup. GazeFollower provides tools for real-time gaze tracking, calibration, and data recording, making it ideal
for applications in psychology, usability testing, and more.

## Features

- **Accurate Tracking**: Achieves high accuracy and precision with built-in calibration methods.
- **Pythonic API**: Easy-to-use, with functions for common tasks like calibration and data saving.
- **Lightweight & Fast**: Optimized for real-time performance, ensuring smooth operation on most systems.
- **Experiment Ready**: Includes methods for triggering and saving data, ideal for experiment-based applications.

## Installation

You can install GazeFollower via pip or by cloning the repository.

### Installing with pip

```bash
python -m pip install gazefollower
```

### Git clone from Github

```bash
git clone https://github.com/GanchengZhu/GazeFollower
cd GazeFollower
python setup.py install
```

## Quick Start

Here's a basic example of how to use GazeFollower:

```python
# _*_ coding: utf-8 _*_

import pygame
from gazefollower import GazeFollower

gaze_follower = GazeFollower()

gaze_follower.preview()
gaze_follower.calibrate()

gaze_follower.start_sampling()
# your experiment code here
gaze_follower.send_trigger(10)
pygame.time.wait(5)
# your experiment code here
gaze_follower.stop_sampling()
gaze_follower.save_data("demo.csv")
gaze_follower.release()
```

More detailed usage information can be found [here](MORE_INFO.md).

## Note

This depository contains a model train on 7 million images that is sufficient for most applications. 

To gain access to the base model trained on 32 million images, please email zhiguo@zju.edu.cn.

### Email Prompt

Here鈥檚 a template for your request email. Please keep the subject line unchanged:

```
Subject: Request for Access to the Base Model Trained on 32 Million Images

Dear Prof. Zhiguo Wang,

I hope this message finds you well.

My name is [Your Name], and I am a [student/researcher] at [Your Affiliation]. I am writing to request access to the base model trained on 32 million images.

I assure you that I will use this model solely for academic and research purposes and will not utilize it for commercial activities or share it with others.

Thank you for considering my request. I look forward to receiving access to the model.

Best regards,
[Your Name]
```

### The Usage of The Base Model Trained on 32 Million Images

```python
import pygame
from gazefollower import GazeFollower
from gazefollower.gaze_estimator import MGazeNetGazeEstimator

# The base model path need to pass here
gaze_follower = GazeFollower(gaze_estimator=MGazeNetGazeEstimator(model_path='path to model'))

gaze_follower.preview()
gaze_follower.calibrate()

gaze_follower.start_sampling()
# your experiment code
gaze_follower.send_trigger(10)
pygame.time.wait(5)
# your experiment code
gaze_follower.stop_sampling()

gaze_follower.save_data("demo.csv")
gaze_follower.release()
```
