Query: The design of interactive systems for children is a crucial aspect of HCI research, as it can significantly impact their learning experience and cognitive development (Chimbo et al. 2011). Educational apps for children have been shown to have a low-quality visual and interaction design, with content that mirrors problems in the school curriculum (Crescenzi-Lanna et al. 20161)(Crescenzi-Lanna et al. 20162). Moreover, the label "educational" or "for children" does not indicate that an app has been validated and tested (Crescenzi-Lanna et al. 20162). Therefore, it is essential to ensure quality design and content in children's apps and their adaptation to different developmental stages in children.

Designing for young users in digital learning tools requires consideration of their developmental stage when formulating content and activities, as well as employing an appropriate interaction design to their cognitive development (Crescenzi-Lanna et al. 20162)(Crescenzi-Lanna et al. 20163). The interaction design should be simple, with minimal distractors and active elements on the screen that are unnecessary (Crescenzi-Lanna et al. 20162). Moreover, the content of the apps should clearly align with the interests and abilities of potential users, and adapt to the needs of the target group (Crescenzi-Lanna et al. 20162)(Crescenzi-Lanna et al. 20163).

Affordances in educational app design are crucial in making the app user-friendly and accessible for children (Chimbo et al. 2011). Feedback mechanisms in children's interfaces should be designed to provide clear and timely feedback to the user (Altarawneh et al. 2017). Consistency and constraints in child-friendly applications should be considered to ensure that the app is easy to use and understand (Altarawneh et al. 2017).

Gamification in children's educational apps can be an effective way to improve engagement and motivation (Palomino et al. 2024). However, gamification should be used in a way that is appropriate for children and takes into account their cognitive and physical development (Palomino et al. 2024).

Moreover, the engagement and accessibility of children's apps are critical factors that can impact their learning experience (Palomino et al. 2024). Improving engagement in children's apps can be achieved through the use of gamification, rewards, and motivational design principles that are tailored to their needs and abilities (Palomino et al. 2024). Accessibility challenges in children's user interfaces can be addressed by employing universal design principles, such as simplicity, consistency, and feedback (Chimbo et al. 2011).

Touch interaction patterns in children's applications should be designed to be intuitive and easy to use, taking into account their cognitive and physical development (Chimbo et al. 2011). Designing for cognitive and physical development in children requires consideration of their age, abilities, and needs (Chimbo et al. 2011). Finally, HCI guidelines for designing for young children should prioritize simplicity, consistency, and feedback, as well as considering their cognitive and physical development (Chimbo et al. 2011).

In conclusion, designing interactive systems for children requires a deep understanding of their developmental stage, cognitive and physical abilities, and needs (Chimbo et al. 2011). By considering these factors and employing design principles such as affordances, feedback mechanisms, consistency, and constraints, we can create educational apps that are engaging, accessible, and effective in promoting their learning experience (Crescenzi-Lanna et al. 20161)(Vanderschantz et al. 2018)(Sun et al. 2019)(Crescenzi-Lanna et al. 20162)(Crescenzi-Lanna et al. 20163)(Palomino et al. 2024)(Altarawneh et al. 2017)(Chimbo et al. 2011).
