A little history: the origin of eye tracking
Posted: Mon Dec 23, 2024 4:37 am
Eye tracking seems like a new technology , but it actually dates back to the 19th century.
I will only tell you two very curious facts about its history:
In 1879, Louis Emile Javal, a renowned French ophthalmologist, observed that we do not read by making a smooth scan of the text, but rather by making a series of short fixations or stops and what are known as saccades, rapid movements.
Like this:
Eyetracking - Example of fixations and saccades during reading.
The second fact is even better:
In 1950 Alfred L. Yarbus did some very important research on eye tracking.
In one of his experiments he showed an image and depending on the instruction he gave, the eye movement and search intention changed.
Eyetracking - Yarbus Experiment.
For example:
In painting #1 he let the person look freely.
In box no. 3 he asked for a specific task: to give the age to th dubai number for whatsapp e people in the photograph.
It is very interesting to see how the visual path changes when the search intent changes.
As early as 1950, users changed their behavior and attention points based on their intention.
In this sense, it seems that we have not changed much, right?
From here we can extract our first key to eye tracking.
Tip #1: It’s essential to consider users’ motivations and intentions.
With this clue in mind we can return to the case.
And at this point, you need to know the suspects so you know their motivations.
The case of “La douce Fleur”: how to solve a mystery using eye tracking
The night the robbery occurred there was a celebration.
There is one important clue: a photo from the end of the party in which only four people remain.
Eyetracking - The Suspects
They are the prime suspects as evidence indicates that the burglar did not have to force his way into the house.
