The paper presents a multi-domain approach to design of CyberPhysical-Systems, especially in special education. The domains of game design for education and the control systems design are merged into the domain of novel educational technology design. The approach is tested within the recent EEA Grant project of Bulgaria and Norway "METEMSS: Methodologies and technologies for enhancing the motor and social skills of children with developmental problems". A formalized model is proposed to account for the nature and direction of the incremental game transformation based on the preferences of the individual child. The results provided statistically significant difference in the desired direction of game change. Examples with humanoid and non-humanoid educational robots are discussed with relevance to the topic of COST Action IC1404 WG3 Application Domains.
