The paper presents a practical approach for education and training, based on computer assisted, research-focused exercises in mixed cyber-physical realities. A respective solution has been developed in the last several years, encompassing academic research and training experience both at national and international level as a tool for verification of future cybersecurity transcedents. Special emphasis is placed on the polygon design and implementation, and user feedback from the usage for multimodal and multicriteria assessment of training effectiveness. Finally, the paper outlines some future trends towards extending mixed realities, advancing user monitoring and more effective and efficient training.
