Intervention(s)

Work on the writing task for 5 minutes without using the dotted underlays. We use TraceCoder to trace shapes before and after the task, and calculate the area of trace misalignment, writing pressure and measurement time.
Using the dotted underlays, students work on the writing task for 5 minutes. We use TraceCoder to trace eight different shapes before and after the task, and calculate the area of trace misalignment, writing pressure and measurement time.

Outcome(s)

• Primary Outcome: We use TraceCoder to trace shapes before and after the task, and calculate the area of trace misalignment, writing pressure and measurement time. For analysis, we calculate the "amount of change in writing pressure with/without underlining" and "change in displacement area per unit time with/without underlining" and compare the difference. Additionally, we examine the participants' motor coordination, sensory characteristics, and eye movements, dividing them into the complex and standard groups and comparing the two groups.
