Well, first, you should know that hand-eye coordination is the ability of the body to use what the eyes are looking at to direct the hands in motion. And generally speaking, it occurs for most people, and it is involved in activities such as playing sports or video games. To improve hand-eye coordination, you can play video games which require lightning-quick hand-eye coordination. Also, you can just grab some coloring books and crayons and color away, because it is a creative way to control your hands and fingers to do what your eyes coordinate them to do within the confines of the page. So just have a try.
Hand-eye coordination is the ability of coordination between hand and eye. The vision system gets information through eyes and uses this information to direct and guide our hands to execute a given task, for example, getting a flying ball or handwriting or anything we do. This ability starts to develop since infant period. When we were born, we started to see with eyes, and gradually we learned to move small objects with eyes, such as reaching and grasping. As we grew older, our hand-eye coordination skills developed that we can do more skilled work such as playing basketball, driving, dancing and so on. Inadequate hand-eye coordination is mainly caused by two problems, vision impairment and movement disorders. Because vision is impaired, people can't see objects clearly. The blurry or impaired vision directly impacts hand-eye coordination ability. Although people might have good vision, yet movement disorders stand in the way of task fulfillment too. The typical example is ataxia. The eyes give correct and fully direction, yet body movement can't handle it at all. Hand-eye coordination exists around us. What we do daily requires this ability, which is necessary and critical.
