Toddler Sensory-Motor Development for Object Manipulation by Analyzing Hand-Pose

A toddler learns to hold various types of objects using hands in their everyday life without any specific instruction from an adult. The main media of interaction happens using the hands. A toddler's sensory-motor is developed by manipulating various types of objects. Exploring object holding-activity of a toddler can provide new insight into how sensory-motor develops in the formative years. Goal of this research is to learn how a toddler develops the sensory-motor system from directly hand interaction of an object. A video dataset was developed to study the patterns and hand-pose of a toddler while using their hands to hold an object. The birds-eye view of the scene was captured using a top-mounted camera, where the toddler was interacting with various types of objects with hands. Parents were guided to engage their child to interact with the object. The different hand-pose of the toddler's hands were observed, while the toddler was manipulating different types of objects. A detailed analysis result has presented on the hand-pose distribution of a toddler's hands for object holding-activities.
