TL;DR: Eye gaze is utilized as a medium to unravel the cues utilized by humans for the perception of facial aging and explore the tasks of face age estimation and age-separate face verification and analyze the eye gaze patterns of participants to understand the strategy followed by human participants.
Abstract: Continuous efforts are being made to understand human perception network with the purpose of developing enhanced computational models for vision-based tasks. In this paper, we utilize eye gaze as a medium to unravel the cues utilized by humans for the perception of facial aging. Specifically, we explore the tasks of face age estimation and age-separate face verification and analyze the eye gaze patterns of participants to understand the strategy followed by human participants. To facilitate this, eye gaze data from 50 participants is acquired using two different eye gaze trackers: Eye Tribe and GazePoint GP3. Comprehensive analysis of various eye movement metrics is performed with respect to different face parts to illustrate their relevance for age estimation and age-separated face verification tasks.

TL;DR: In this paper , the most used devices and libraries in gaze tracking solutions in the last 5 years as well as the most important characteristics of each of them are presented, based on features such as price, technical performance and compatibility.
Abstract: Gaze tracking is a technological discipline that offers an alternative interaction between human and computer. A common solution based on gaze tracking has two elements: a hardware device to obtain data from user’s gaze and a library to process the gathered data. This work makes a formal analysis of previous works in gaze tracking. It presents the most used devices and libraries in gaze tracking solutions in the last 5 years as well as the most important characteristics of each of them. To fulfill this purpose, a search for articles related with eye tracking solutions was carried out in different scientific databases. After that, a classification of results was made, as well as a review of them. In addition, the article offers the areas of IoT in which gaze tracking has had the most influence. Finally, various selection criteria for devices and libraries are offered. These criteria are based on features such as price, technical performance and compatibility.

TL;DR: This paper presented a theoretical account of the sequence and duration of eye fixation during simple cognitive tasks, such as mental rotation, sentence verification, and quantitative comparison, and linked the eye fixation behavior to a processing model for the task by assuming that the eye fixates the referent of the symbol being operated on.

TL;DR: In this paper, it is argued that focused attention provides spatiotemporal coherence for the stable representation of one object at a time, and that the allocation of attention can be co-ordinated to create a virtual representation.
Abstract: One of the more powerful impressions created by vision is that of a coherent, richly detailed world where everything is present simultaneously. Indeed, this impression is so compelling that we tend to ascribe these properties not only to the external world, but to our internal representations as well. But results from several recent experiments argue against this latter ascription. For example, changes in images of real-world scenes often go unnoticed when made during a saccade, flicker, blink, or movie cut. This “change blindness” provides strong evidence against the idea that our brains contain a picture-like representation of the scene that is everywhere detailed and coherent. How then do we represent a scene? It is argued here that focused attention provides spatiotemporal coherence for the stable representation of one object at a time. It is then argued that the allocation of attention can be co-ordinated to create a “virtual representation”. In such a scheme, a stable object representation is formed...

TL;DR: The first work involving age classification, and the first work that successfully extracts and uses natural wrinkles, is also a successful demonstration that facial features are sufficient for a classification task, a finding that is important to the debate about what are appropriate representations for facial analysis.
