Dikablis D-LAB

The module for automated data analysis

Automatic data analysis

You want to analyse your gathered eye-tracking data in the quickest way and with high quality? Then our module D-LAB for automatic data analysis is perfect for you. D-LAB enables the user to automatically determine the number and duration of distracted glances to freely definable Areas of Interest (AOI) as well as the automated calculation of the grade of glance activity. Thus we offer you the experience we made in years in calculating significant characteristic values.

Operating mode

To automatically calculate the number and duration of distracted glances to AOIs, you merely have to place the delivered D-LAB markers close by. The D-LAB markers
can be installed easily and anywhere. Thus an automated analysis can be made which is independent of the geometric marginal conditions. Image processing algorithms detect the markers in the image of the field of vision camera and so the D-LAB software is able to calculate the head posture in the room. You can freely define for which AOIs an automatic analysis is to be made. Therefore the D-LAB software offers a definition mode in which the AOIs can be indicated via connected line segments.

Automatic calculation of characteristic values

This function enables an automatic calculation of characteristic values of distracted glances to AOIs which were defined in advance and of the grade of glance activity. You can either calculate these characteristic values for a complete project, for individual experiments or for certain periods within an experiment. For example, the following characteristic values can be calculated in an automated way:

  • Cumulative gaze duration to an AOI [s]
  • Number of glances to an AOI [-]
  • Maximum gaze duration to an AOI [s]
  • Average gaze duration to an AOI [s]
  • Visual searching activity in [°/s]
  • Average saccade angel in [°]
  • Medial fixation duration in [s]

We want your results to be 100% reliable! That is why D-LAB offers a replay mode with which you can check the automatic. Thereby D-LAB tags the recognized markers and highlights an AOI when the test person is watching it. If the image processing algorithm actually does not recognize a marker, it can be marked manually afterwards.

HeatMap design

You want to analyze your results thoroughly and present them to your customer in an impressive way? Our HeatMap display is perfect for that. The auxiliary module offers a dynamic and a static display of the concentration of gaze distribution for a definable time interval.

Using the dynamic HeatMap, the plot of gaze distribution is displayed for a running time slot while watching the eye-tracking video. Glances at the end of the adjustable time slot disappear and new glances are added. Thereby red pixel fields mark areas which were viewed often and blue pixel fields mark areas which were viewed less. If the time slot is set up to 2s, the HeatMap visualizes for example the information which is in the test person’s short-term memory, while watching an eye-tracking video.

Using the static HeatMap, the plot of gaze distribution builds itself up for a complete eye-tracking video while watching it. Thus, for example, the gaze movement and the distribution of attention while watching an advertisement or a website can be displayed and precisely analysed. Additionally, the plot of gaze distribution, which is transparently overlaid on the image of the field of vision camera, can be saved as picture file for any definable time interval and can so be integrated in presentations or reports.

Naturally, the application can be used for dynamic objects. Thus it is also possible to analyse the eye-tracking data via the HeatMap when using a PDA or a mobile phone. The plot immediately gives a feedback signal about at which area the user glances most. It is possible to particularly identify the areas which are not noticed at all.

Thus a direct potential for improvement is immediately observable and can be used.
