Feasibility of measuring eye–hand coordination in children with developmental delay using Sanet Vision Integrator

Abstract

Eye–hand coordination is a visuomotor task that enables one to look, localize, and touch objects. Eye–hand coordination is known to be poor in children with developmental delay. In this study, we assessed the feasibility of measuring eye–hand coordination task in children with developmental delay using Sanet Vision Integrator (SVI), a commercially available device. Children (age: 3–16 years) with developmental delay and their age-similar typically developing peers were enrolled. White circles (5.5°) on a black background were presented on the SVI touch screen monitor. Participants popped these circles by touching it. Reaction time, accuracy, and an overall performance score were computed. Participants could perform the task from 4 years of age and with visual acuity 20/400 (6/120) or better. This resulted in 85% (17/20) of children with developmental delay and 95% (19/20) of typically developing children completing the task. Children with developmental delay were significantly ( p < .001) less accurate (56%) and took longer (2.63 s) to complete the task when compared with their peers (accuracy = 93%, reaction time = 1.46 s). The overall performance score of children with developmental delay was also lower than their peers by a factor of 3.3. Eye–hand coordination performance can be measured and quantified with SVI. The quantification of speed and accuracy is possible and a unitary measure combining speed-accuracy can be computed. The task can be performed both by typically developing children and by children with developmental delay. Thus, it is feasible to measure eye–hand coordination using SVI. Such quantification will be useful for children undergoing interdisciplinary therapies for their medical conditions.
