Evaluation of Grip'n'Play

The goal of this study is to evaluate Grip'n'Play, a set of tablet games controlled with the SensoGrip pen, which provides visual feedback on grip and writing pressure. The games are designed to encourage preschool and early school-age children to gain experience using a pen and to practice pressure control in a playful way. The main questions this study aims to answer are: * Are the Grip'n'Play games technically reliable and easy to use? * Do children enjoy and accept the games? * Are children motivated to use the games? * Do children use the games regularly compared with a handwriting practice workbook? Participants will: * Use both, the Grip'n'Play game, and a practice workbook for handwriting-related activities. * Complete the activities over the study period. * Provide information about their experience, motivation, and use of the activities through study assessments conducted by the research team.
