Thanks for your registration!

For each area of application we offer a specific version of the Human Efficiency Evaluator. We offer a free license for evaluation purposes and for application in publicly funded research projects or for academic purposes at universities. License files are provided via email.

Version for Visual Attention Prediction

The current version for predicting visual attention can be downloaded following this link:

HEE – Attention Stable Version

You should have received the license file via email from us. This file needs to be copied into your user home directory (usually a folder under “c:\users\”).

A short video tutorial might help you to start with the attention modelling.

To evaluate the software we offer an Exemplary Project File that you can just open and edit with the tool. This project is about modeling the attention of a car driver for an overtaking maneuver in three phases: “left merge”, “overtake”, “right merge”. After you have finished the modeling process the tool generates a ZIP archive with all the data.

Feel free to send us this ZIP file and we will provide you with the attention prediction results in return.
