Design outcomes

Primary

MeasureTime frame
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.
