청각 기능에 문제가 생겨 소리를 잘 듣지 못하는 청각장애인은 육아를 위해 베이비시터를 고용하거나 청각장애인용 소리감지 시스템을 사용하지만, 이는 비용적으로 부담이 될 수 있다. 이러한 문제를 해결하기 위해 사운드 센서 기반의 아기 울음소리감지 시스템을 제안한다. 이는 아기가 있는 곳에 소리감지 시스템을 설치하고, 일정 크기 이상의 소리가 감지되면 손목시계 모양의 웨어러블 디바이스에 진동을 발생시켜 아기가 울고 있음을 알려준다.

Many deaf parents are the most difficult points, while child care does not hear the cries of the child points. So, because the child is hungry or cry cry aloud immediately respond when asked to change the gwijeogi should be possible with the help of additional equipment or others. To address these challenges of parenting using IT technology to solve by developing an Android application that provides a notification to your device instead of using the Arduino equipped with a microphone that measures the cries of the children and your parents. These systems by informing the sounds of children apart from the child and the parents must become a help to the communication of deaf parents and children.

최근 주변 사물과 IT기술을 접목하여 사람들의 불필요한 시간을 줄여주는 제품들이 각광받고 있고 이러한 제품들을 구현하기 위한 다양한 임베디드 디바이스 또한 많은 개발과 발전을 하였다. 본 프로젝트는 아두이노와 스마트 디바이스의 통신을 통해 아이의 위기와 이상을 감지하여 물리적 먼 거리에서도 보호자가 위기 상황을 감지할 수 있도록 통보하는 디바이스를 개발하였다. 아두이노와 사운드 센서를 기본 디바이스로 아이의 울음을 감지하고, wifi 쉴드를 통해 데이터를 저장하며 스마트 디바이스는 이를 감지하여 부모에게 필요한 정보를 전달하여 보호가 필요한 아이의 위급 상황에 빠른 대처가 가능하게 하였다.

The core of existing IT industry has been multimedia contents based on internet network. But nowadays, ubiquitous technology which combines sensors and network technology is emerging and is called USN (ubiquitous sensor network). Health care industry is one of suitable areas for USN application. In this paper, sensor network for baby care is proposed. The proposed baby care system consists of bluetooth network to transfer information which comes from various sensors like falling detecting, crying and fever detecting sensor to keep infant's status safe from external-potential threats. The effectiveness of the implemented system is showed through demonstration.

This significance of the infant care system has emerged due to sudden infant death during sleeping. This paper presented a design and implementation of a prototype model, which is a infant care device controlled by a smartphone using Bluetooth technology. Prototype Device Model consists of MCU(microcontroller unit), Accelerometer Sensor, Temperature Measuring Sensor, Sound Measuring Sensor, Bluetooth Module, and Camera Module. The proposed application transfers the information to the parent's smartphone and computers, such as infant's falling, crying, and fever detection. A test verified the availability of a prototype infant care system model using Bluetooth Low Energy with operating the low power driving.

This paper is about a smart pillow, and a smart diaper. The smart pillow analyzes the frequency of a baby's cry and applies its digital value to the band pass filter. If the crying is between 300-600Hz, the white noise comes out. The smart diaper alerts to the smart phone if the humidity outside the diaper is over 99%, or the temperature is over $29^{\circ}C$ after the defecation of the baby. The smart diaper also prevents choking of the baby by alert to smart phone if they are in a dangerous position by sensing the location of the infant.
