Detailed Description

The study hypothesis is that both laypersons and health-care providers will have difficulty estimating length and depth. The study will enroll 100 laypersons and 100 health-care providers. The participants will be asked to draw a 5cm line without assistance an estimate 5cm depth to measure accurateness of length and depth estimation.
