Parents may have experience about not figuring out why their baby’s wailing. The reason is babies can only express their need by crying. If parents don’t recognize what does the baby want, it will cry harder, and parents will become more anxious. Then, it turns into a vicious circle. Fortunately, the sign language for infants and toddlers prevents this situation. In the light of this, we learned that baby sign language is a way for parents and children to communicate, expressing their thoughts and needs through some simple gestures or body language. Baby sign language is a modification from that for the hearing-impaired. Also, it refers to the interaction between hearing-impaired kids and their family. Thus, it becomes the best tool for communication for children who are in the transition period of verbal development. Nowadays, most teaching materials of the sign language for children on the market are graphic cards. They are unable to attract children‘s attention for a long time, not identify the gestures easily, either. This may bring on parents losing their confidence and giving up teaching.
" B To Say " is the expert-designed teaching aids of sign language for children between 7months to 3 years old and their family. First, parents should download the app and open it. Next, prepare the teaching aids. Then, lead their baby to put a block in the right position on the tool and beat it. After that, the app will demonstrate an animation of what’s the situation to use as well as the gesture of the sign language. As the result, they can learn it well and repetitively. It classifies the terms into five categories: BASIC, ACTION, LIFE, NATURE, and OTHERS by feasibility. Initially, we suggest that parents start from basic terms to guide the baby expresses its needs by sign language.
" B To Say " has several benefits. It challenges baby’s cognition and hand-eyes coordination because baby need to match the right shape of the block to show the animation. Also, it appeals baby’s interest and increases the interaction between human and the machine. Last, it is convenient to storage due to its special space for pad. It will not only improve this issue, but also make the children interact with adults earlier. Thereby they will be better at communication skill, language, cognition and intellectual development.
