Development of an Assistive Device for Elderly Bedbound People to Share Needs with Caregiver and Control Home Appliances

Most of the cases, the family members act as the caregiver of elderly bedbound people in the middle-class family of Bangladesh. An elderly bedbound people have to share their all needs with their family members. It is challenging for older people to draw the attention of the caregivers by calling with a loud voice to share their needs if caregivers are not close to them. This research is to design an assistive device that can help the bedbound older people to share their requirements with caregivers. The device has two parts: transmitter and receiver. The transmitter device has several PUSH buttons. Every PUSH button is tagged with different needs. When older adults press a PUSH button, the information is transmitted to the receiver device via Bluetooth technology. Then the receiver device plays a different tone for different needs in a buzzer and also shows the essentials in an LED matrix display. Besides, older people can also control home appliances like light, fan, etc. by this device. The device can play a significant role in improving the quality of the daily life of older adults.
