The emergence of natural user interface NUI adds infants with more herbal interaction. However, NUI developed are commonly inappropriate for his or her age, because of the missing in understanding of their needs and the problems they face. This paper gifts a research on herbal user interface NUI for little ones where the understanding of the issues of usage and their requirement was gathered from literature review and evaluation of a usability study. The identification of usability issues were collected from an observation analysis of two kinds of NUI: free form represented by Kinect; and touch form represented by tablet iPad.
Our statement from video recording evaluation and interviews discovered that touch form NUI is harder to recall, but its simple and easy gestures are easier to be performed as long as it doesn’t contain finger gestures. On the other hand, free form NUI is more herbal and easier to recall but unluckily troubled by many unwanted gesture interpretations. By using analytical model, these findings were inter associated with input system output point of view that help us to suggest concepts to improve NUI interplay and proposes a NUI prototype design to aid infants in studying.
