User Experience (UX) Evaluation of a Tablet-Based Cognitive Training System for the Prevention of Mild Cognitive Disorders : Evaluation of Cognitive Function, Learning Outcomes, Usability, and Emotional Response in Paper- and Tablet-Based Cognitive T

As the elderly population grows, the demand for learning programs to prevent mild cognitive impairment is increasing. This study examined the potential of a tablet-based cognitive training system for older adults by comparing digital- and paper-based learning in terms of cognitive function, learning outcomes, ease of use, and emotional response. Fifty participants aged 65–90 were randomly assigned to two groups and completed the same two-day cognitive training program. Data from pre- and post-tests (K-MMSE), correct answer counts, time required, and usability and emotional response questionnaires were analyzed using t-tests and Pearson correlation. The digital learning group was rated higher for its repetitive learning structure and self-directed usability, showing more correct answers and longer engagement. These results suggest that digital cognitive training systems can enhance learning efficiency in older adults and emphasize the need for customized UX design and long-term effect verification.
