Fine motor skill development is essential for children's academic and cognitive growth, particularly in relation to handwriting. However, traditional training methods may lack engagement and adaptability, especially for children with motor difficulties such as dysgraphia. This study presents the design, implementation, and pilot evaluation of serious games developed using the SensoGrip system-a pressure-sensitive pen equipped with multiple sensors for real-time motor skill tracking. Building upon prior research in occupational therapy and sensor-based feedback, sensor data received from the SensoGrip is integrated into custom-designed mini-games built in the Unity engine. These games leverage pressure, tilt, and motion input to create interactive mechanics that promote controlled pen use and motor coordination. The paper outlines a structured development process and details how sensor inputs were mapped to gameplay elements to ensure educational relevance and intuitive usability. A pilot test with preschool children provided insights into user comprehension, motor skill limitations, and the need for intuitive feedback design. The results highlight the potential of sensor-integrated serious games as engaging tools for early handwriting intervention and motor training, while also identifying areas for future refinement and broader empirical validation.
