Eye- Hand Coordination
This plays a very important part in a Child Education from
the day they are born.
Eye-hand coordination is a crucial athletic skill involving how effective we are at translating what our eyes see into appropriate physical responses .Eye-hand coordination is the ability of the vision system to coordinate the information received through the eyes to control, guide, and direct the hands in the accomplishment of a given task, such as handwriting or catching a ball. Hand-eye coordination uses the eyes to direct attention and the hands to execute a task.
Children are learning to draw, they follow the position of the hand holding the pencil visually as they make lines on the paper. Between four and 14 months of age, infants explore their world and develop hand-eye coordination, in conjunction with fine motor skills. Fine motor skills are involved in the control of small muscle movements, such as when an infant starts to use fingers with a purpose and in coordination with the eyes.
Infants are eager to move their eyes, their mouths, and their bodies toward the people and objects that comfort and interest them. They practice skills that let them move closer to desired objects and also move desired objects closer to themselves. By 6 months of age, many infants begin reaching for objects quickly, without jerkiness, and may be able to feed themselves a cracker or similar food. Infants of this age try to get objects within their reach and objects out of their reach. Many infants are also able to look from hand to object, to hold one object while looking for a second object, and to follow the movements of their hands with their eyes. At this age, most infants begin to poke at objects with their index fingers. After six months, infants are usually able to manipulate a cup and hold it by the handle. Many infants at this age also begin to reach for objects with one arm instead of both. At about 8 months of age, as dexterity improves, many infants can use a pincher movement to grasp small objects, and they can also clap and wave their hands. They also begin to transfer objects from hand to hand, and bang objects together. Hand-eye coordination development milestones are as follows.
Birth to 3 years
Between birth and 3 years of age, infants can accomplish the following skills:
3 to 5 years
Between 3 and 5 years of age, little children develop or continue to develop the following skills:
5 to 7 years
Children between 5 and 7 years old develop or continue to develop the following skills:
Problems with Eye-Hand coordination
Eye-hand coordination problems are usually first noted as a lack of skill in drawing or writing. Drawing shows poor orientation on the page and the child is unable to stay "within the lines" when using a coloring book. Often the child continues to depend on his or her hand for inspection and exploration of toys or other objects. Poor hand-eye coordination can have a wide variety of causes, but the main two conditions responsible for inadequate hand-eye coordination are vision problems and movement disorders.
Vision impairment is a loss of vision that makes it hard or impossible to perform daily tasks without specialized adaptations. Vision impairment may be caused by a loss of visual acuity, in which the eye does not see objects as clearly as usual. It may also be caused by a loss of visual field, in which the eye cannot see as wide an area as usual without moving the eyes or turning the head. Vision impairment changes how a child understands and functions in the world. Impaired vision necessarily affects a child's hand-eye coordination, as well as cognitive, emotional, neurological, and physical development by limiting the range of experiences and the kinds of information to which the child is exposed.
Movement disordersMovement disorders are characterized by impaired body movements. They have a variety of causes. An example is ataxia, characterized by a lack of coordination while performing voluntary movements. The problem may appear as clumsiness, inaccuracy, or instability. Movements are not smooth and may appear disjointed or jerky. Another example is hypertonia, a condition marked by an abnormal increase in muscle tension and a reduced ability of a muscle to stretch. Whatever their origin, movement disorders almost always prevent the normal development of hand-eye coordination.
Ataxia—A condition marked by impaired muscular coordination, most frequently resulting from disorders in the brain or spinal cord.
Binocular vision—Using both eyes at the same time to see an image.
Convergence—The natural movement of the eyes inward to view objects close-up.
Fine motor skill—The abilities required to control the smaller muscles of the body for writing, playing an instrument, artistic expression and craft work. The muscles required to perform fine motor skills are generally found in the hands, feet and head.
Gross motor skills—The abilities required to control the large muscles of the body for walking, running, sitting, crawling, and other activities. The muscles required to perform gross motor skills are generally found in the arms, legs, back, abdomen and torso.
Hypertonia—Having excessive muscular tone or strength.
Motor skills—Controlled movements of muscle groups. Fine motor skills involve tasks that require dexterity of small muscles, such as buttoning a shirt. Tasks such as walking or throwing a ball involve the use of gross motor skills.
