The Best Eye-Tracking Software
The next big thing in technology is the eye-tracking industry, thanks to the promising results it brings. Companies currently use results from eye-tracking software to ascertain the behaviors of their clients exemplarily. These behaviors are then used to draw reliable insights from the clients.
We have the best eye-tracking software in the market today, thanks to the hardworking technology team at Gaze Point. So, if you seek the best eye-tracking services in the USA, look no further than Gaze Point. This article outlines what our eye-tracking devices entail and how they execute the process.
Eye-Tracking Software – A Definition
Our eye-tracking software is a vital technology that draws essential information about human behavior and cognitive functions. Applications of this software are limitless, with utility both in the research and commercial sectors.
Eye-tracking generally allows us to measure the eye movements, positions, and points of gaze. It simply identifies and records an individual’s visual attention based on location, objects, and time.
Generally, gaze tracking software is a technology that offers valuable intuitions and opportunities to the users from their clients. To unpack the complexity surrounding it, let’s evaluate some vital information about what the best eye-tracking technology should look and be like and how it functions.
The best eye-tracking technology is often mentioned regarding:
- Monitoring the blinking patterns
- Identifying what the subjects/users looks or does not look at
- Assessing the pupil reaction when a visual or emotional stimulus is presented
- Facilitating the interaction between humans and computers in machine learning
What Should a Good Eye-Tracker Software Measure?
The best eye-tracking software such as those at Gaze Point must be able to track the following:
The eye executes several movements, including the vergence and torsional directions. However, the most relevant ones needed in eye-tracking include fixations, saccades, and smooth pursuit.
Fixations are movements that occur when the eye momentarily stops to record visual data. Although the duration of different fixations varies, the longer the fixation, the more visual data is collected.
Saccades refer to fast jumps performed between various fixations in an inert environment. Saccades involve eye movement from an object of interest to another, intending to collect new graphic data in the highest resolution.
Smooth pursuit refers to the movement when the eye looks at a moving object and follows it. The eye takes in much visual data during smooth pursuit, so it’s a relevant movement in eye tracking.
A resourceful eye-tracking software must also be able to measure and analyze pupil size. To get accurate pupil tracking data, the environment must be rigorously controlled.
Some inadequate test conditions that can cause inappropriate pupil dilation while tracking include:
- Strong emotional stimuli
- Acute attention
- Load on the working memory
Most importantly, a good eye-tracking facility must measure one’s visual attention.
Because image processing resources are limited, the brain chooses relevant visual information with regard to:
- Interest – This is the unconscious or conscious decision to gaze at an object
- Environment – These are the elements visible through peripheral vision
Working Process of the Best Eye-Tracking Device
A good eye-tracking software must be able to follow eye positions non-intrusively. Mainly, they apply an infrared light that invisibly illuminates the eye, thus generating a reflection in the cornea. An infrared camera is then used to record the reflection to delimit the pupil center, infer eye rotation, and determine the gaze’s direction.
This is called the Pupil Center Corneal Reflection (PCCR) and is a formal reference term for the primary method used by eye tracking to deduce and monitor corneal reflections.
Finally, to infer from the recordings, advanced mathematical algorithms are used to calculate the eye position, gaze point, and eye movements. The software must also be able to convert the recorded information into raw data.
What Metrics Do We Use?
There is a variety of metrics that eye-tracking software uses to inspect the collected data, and they are as follows:
Fixations – Fixations and saccades together formulate a scan path from the subject’s eyes’ trail.
Gaze points and plots – The gaze point metric shows the exact spot where the respondent was looking, while a plot creates a visualization for the scan path. Combined gaze plots can be used to evaluate the scan paths of many respondents to recognize behavior patterns.
Areas of Interest – Areas of interest enable the selection of the specific regions in a particular scene.
Ratio is the number of respondents who fixated on a specific AOI. Dwell time refers to the total duration of observation of an AOI. Observation count refers to the frequency of a participant visiting an AOI.
Heat Maps – Heatmaps are innovative visualization tools that illustrate the distribution of the fixations and gaze points. In eye-tracking, heat maps use the principle that the more fixations there are at a certain area, the redder it becomes.
Eye-tracking is a rapidly evolving industry because demand is still being created, and new developments and trends emerge. Soon, we will be able to study the behavior of humans concerning the natural living environment.
