Hand-eye coordination

Hand-eye coordination is the ability to use visual information to guide and adjust hand movements. It combines visual processing, motor planning, and feedback during action.

Visuomotor integration: The process of transforming visual information into motor commands. It is the broader process that links visual input to the hand’s actions.
Saccade: A rapid eye movement that shifts the point of gaze from one location to another. Gaze shifts help place visual attention where the hands need to act.
Visual perception: The interpretation of visual information to identify objects, patterns, and spatial relations. Accurate hand actions depend on perceiving targets and their locations.
Eye-hand dominance: The relationship between a person's dominant eye and dominant hand. Dominance describes preferred sides, not the ability to coordinate vision and movement.
Optic ataxia: A neurological impairment in reaching toward visually presented objects despite relatively preserved strength. It is a specific breakdown of visually guided reaching after damage to parietal regions.
Visual feedback: Information from vision about the results of an action, used to guide ongoing or future movement. The eyes reveal movement errors that can be corrected while reaching or manipulating an object.
Reaching: An arm movement directed toward a target, often followed by grasping or touch. Reaching is a basic task in which vision guides hand trajectory and endpoint.
Depth perception: The ability to perceive distance and three-dimensional structure from visual information. Judging distance helps set the reach and grasp needed for an object.
Reaction time: The interval between a stimulus and the beginning of a response. Fast responses can occur without precise hand placement or ongoing visual correction.
Developmental coordination disorder: A neurodevelopmental disorder involving persistent difficulty acquiring and performing coordinated motor skills. Difficulty with visually guided manual tasks can be one part of its motor challenges.
