Gaze Estimation: A machine learning approach to determine where a person is looking.
Gaze estimation is an important aspect of computer vision, human-computer interaction, and robotics, as it provides insights into human attention and intention. With the advent of deep learning, significant advancements have been made in the field of gaze estimation, leading to more accurate and efficient systems. However, challenges remain in terms of computational cost, reliance on large-scale labeled data, and performance degradation when applied to new domains.
Recent research in gaze estimation has focused on various aspects, such as local network sharing, multitask learning, unsupervised gaze representation learning, and domain adaptation. For instance, the LNSMM method estimates eye gaze points and directions simultaneously using a local sharing network and a Multiview Multitask Learning framework. On the other hand, FreeGaze is a resource-efficient framework that incorporates frequency domain gaze estimation and contrastive gaze representation learning to overcome the limitations of existing supervised learning-based solutions.
Another approach, called LatentGaze, selectively utilizes gaze-relevant features in a latent code through gaze-aware analytic manipulation, improving cross-domain gaze estimation accuracy. Additionally, ETH-XGaze is a large-scale dataset that aims to improve the robustness of gaze estimation methods across different head poses and gaze angles, providing a standardized experimental protocol and evaluation metric for future research.
Practical applications of gaze estimation include attention-aware mobile systems, cognitive psychology research, and human-computer interaction. For example, a company could use gaze estimation to improve the user experience of their products by understanding where users are looking and adapting the interface accordingly. Another application could be in the field of robotics, where robots could use gaze estimation to better understand human intentions and interact more effectively.
In conclusion, gaze estimation is a crucial aspect of understanding human attention and intention, with numerous applications across various fields. While deep learning has significantly improved the accuracy and efficiency of gaze estimation systems, challenges remain in terms of computational cost, data requirements, and domain adaptation. By addressing these challenges and building upon recent research, gaze estimation can continue to advance and contribute to a deeper understanding of human behavior and interaction.

What is gaze estimation?
Gaze estimation is a machine learning approach used to determine where a person is looking. It is an essential aspect of computer vision, human-computer interaction, and robotics, as it provides insights into human attention and intention. By analyzing eye movements and positions, gaze estimation systems can predict the point of focus or gaze direction of an individual.
How is gaze measured?
Gaze is typically measured by tracking the position and movement of the eyes, along with the head pose. Various techniques can be used for gaze measurement, such as video-based eye tracking, infrared-based tracking, and electrooculography (EOG). In recent years, deep learning methods have been employed to improve the accuracy and efficiency of gaze estimation systems.
How does gaze tracking work?
Gaze tracking works by capturing and analyzing eye movements and positions to determine where a person is looking. It usually involves the use of cameras, infrared sensors, or other tracking devices to monitor the eyes and head pose. Machine learning algorithms, particularly deep learning models, are then used to process the captured data and estimate the gaze direction or point of focus.
What is gaze in vision?
In the context of vision, gaze refers to the direction in which a person is looking or focusing their attention. It is an essential aspect of human perception and interaction, as it provides insights into an individual's attention, intention, and cognitive processes. Gaze estimation techniques aim to determine this gaze direction or point of focus by analyzing eye movements and positions.
