During the transition phase from early intervention to primary education (4.5 years to 8.11 years), children with special needs may encounter difficulties in using digital learning media. The investigators intend to apply the TRIZ analysis method to enhance children's participation in learning. Additionally, the investigators plan to design a preliminary model of learning aids and conduct a trial.

The design of digital learning aids for early childhood education for special children to participate in classroom learning is based on the principle of TRIZ analysis combined with the design of 3D printing technology to explore the needs and design of digital apparatus for early childhood education for special children to participate in classroom learning.

A exploratory study. Part 1: Analysis of Systematic Questionnaires. Thirty questionnaires were collected from users of learning devices based on the theoretical basis of ACCESS-FM.The results of the questionnaire are based on the theoretical concept analysis of TRIZ and are used for the preliminary design of learning aids.Part 2: Analysis of Assistive Device Trial. Five school-age children were recruited from the questionnaires for the preliminary design of learning aids. The results are collected for the digital platform performance (writing and typing tests), the ABILHAND-Kids, the Berry-Buktenica Developmental Test of Visual-Motor Integration, Motor Coordination, and the Children's Learning Devices. Motor Integration, Motor Coordination), the Movement Assessment Battery for Children for Children, Second Edition, the Quebec User Evaluation of Satisfaction with Assistive Technology; QUEST) and side effects.

Data Analysis: The performance and side effects of the digital platform operations before and after training were compared using Wilcoxon Signed Ranked Test. SPSS 20.0 was used and the level of statistically significant difference was set at Alpha<0.05.
