trackball, ํธ๋๋ณผ
A trackball is a type of mouse that moves the cursor on a computer screen by rolling a ball. It's convenient because it doesn't require much wrist movement.
Unlike a regular mouse, it can be used in a fixed position. It is especially popular among designers and those who do graphic work.
