For the data that you are collecting to work optimally with this tool, read more about the Eye tracking experiment that was used to create the tool and try to set similar experiment conditions:
</p>
<p>
In the phase of the data collection, participants were asked to perform tasks on different websites. The list of the websites and the tasks can be found in the expandable tab below.<br />
</p>
<p>
For the recording of the gaze movement the eye tracker device was used in a controlled environment that was the same for all the participants. To collect and temporarily visualize the data the software <b>EYEVIDO</b> was used.
<small></small>
</p>
<p>
The collected data was exported from EYEVIDO and modified to create CSV files that can be used to visualize results using our tool. The structure and example contents of CSV files can be seen in the <b>“Import Data”</b> section.

<p>
Heatmaps can show how the gaze-data of multiple users is distributed over the stimulus (web page content for example). The more fixations are in an area the more "heat" (red) is displayed.
</p>
<p>
A heatmap is a visualization that can show the gaze-data for a big number of participants at once, while still being able to see the stimulus that data is plotted on.
</p>
<div class="media">
<img class="mr-3 mx-auto d-block" alt="Bootstrap Media Preview" src="image/htmp_help.png" />
</div>
<p>
The heat map visualization offers the option to display the participants mouse clicks. With only the heat map visualization it is not possible to analyse the previous attention that led to a mouse click.
With this tool, the user can now click one of the participants mouse clicks to display the history of a gaze path that happened previous to this clicks. This will be visualized as a single participants scanpath with according color
to give detailed information about the chronology and length of fixations. By drawing a rectangle about the mouse clicks of interest, all previous scanpaths of the enclosed clicks will be shown. To adjust the length of a scanpath
history, the user can set the timespan in milliseconds before a click.
By clicking on the background the visualization changes back to the normal heat map

<div id="card-element-685156" class="collapse">
<div class="card-body">
<p>
A scanpath provides information about the search behavior of users who participated in gaze recording. It consists of a sequence of alternating fixations and saccades, which are represented by circles of correlating size,
connected
by lines.
</p>
<p>
An advantage of a scanpath is that the chronology of a path is tracked by numbers. An ideal scanpath would be a straight line to a specified target. Many alterations can be a sign of a usability problem.

Mouse movements visualization can be useful to see the user's intent and focus while browsing a website for example. If there is a large number of mouse movements it can indicate that users were confused.
