Dynamic display

Eye and Pen allows to replay the data previously recorded like if it was done with a tape recorder. So, one may have the “movie” played forward or backward. But it is also possible to apply filters to go “trough” the data based on criteria, for example to jump from pause to pause…

The video below shows the simple play (forward) of a simultaneous record of pen and eye mouvements. Location of the eye’s “line of sight” is marked with a cross shaped icon, wheras pen location is symbolized with… a pencil icon. When the pen left the tablet (“up” pause), a strait line joins this point to the place where the pen will be in touch with the tablet again. As an help, the final product is drawn in blue as a watermark. Then we can see what will be written.

In the second half of the video, you’ll a parallel processing sequence: the subjects continues to write while his eyes jump back to the prime text.

Pauses display

In a first step, one may display the final product (text):

Eye and Pen can display a “static”preview of a protocol, i.e. to display a representation of all the events of a certain type on the production. In the following example, events writing pauses are represented.

A writing pause duration can be displayed as a circle whose diameter width is in relationship with the pause duration: the longer the pause is, the larger the diameter will be.  The circle is centered at the very location where the pen stopped or leaved the paper.

The next example is taken from the same experiment. Only pauses with a duration longer than 50 milliseconds are considered.

Eye movements display

What you’ll see here is a static representation of eye mouvements recorded while writing with an eyetracker. The repesentation show below is a temperature map where the red areas are  locations where the subject’s eyes stayed the most.

Save time

You can link Eye and Pen menus to keyboard shortcuts.

You will find this in the menu Display / Menu shortcuts.

The left panel shows menu entries names  (you may unfold neus to show sub-menus).  The right panel lists available shortcuts and those already used.

Buttons in the middle area can be clicked to associate / deasssociate a menu with a shortcut.

You will see that using the keyboard is faster than moving a mouse cursor and clicking, especially when using sub-menus.

EPKeys is a “tool” software delivered with Eye and Pen. Its function is to send series of keyboard key presses into Eye and Pen, instead of you.

Thus you may proceed to massive data extraction. A bit more of information here:

MakeGroup is an utility software that allows to retrieve lines, columns or even cells within one or more Eye and Pen extraction data files to group data.

Maybe a little more easy to use than writing macros into a spreadsheet ?
