Smart Wearable Device for Blind and Elderly People

Movement for blind and elderly people is a challenging problem as they face many difficulties in their daily life. To overcome this problem most commonly, hand stick is used as a support system. Walking stick helps the user to know the presence of obstacle which is in close proximity but does not facilitate detection of obstacles, pits or water that is in the pathway. It does not give information about the location of the user too. Moreover, blind and elderly people are also in a need to monitor their health conditions such as blood pressure and pulse rate. An intelligent system incorporating multiple features will serve as an optimized device for the blind and elderly people. So, a new concept of smart wearable device with multiple features is proposed in this study which will help both blind and elderly people in their daily life. This device enables the movement of both blind and elder people in any environment and monitor their health conditions as well. In this device different sensors such as ultrasonic sensor, infrared sensor, water sensor, blood pressure sensor, pulse sensor, ADXL335 accelerometer sensor, and GPS/GSM technology are embedded to assist the blind and elderly at various instances. During emergencies the information can be communicated to the registered mobile number. This novel system will make the blind and elder people to move confidently and feel their environment.
