The Design of Walker Appliances for Emergency Detection in Elders

The design of walker appliances for emergency detection in elders aims to support elders and elderly care givers. The appliances consist of emergency function, automatic light function, heart rate monitoring function, walking distance monitoring function and lock function. The emergency function detects accidents with touch sensor modules, angle sensor modules, and emergency necklace. Besides, it alerts the sound signal and messages through Line Notify. The light function detects light intensity with LDR Photo resistor Sensor Module for illuminating and positioning walker in the darkness. The heart rate monitoring function measures pulse waves with heart rate sensor module. The walking distance monitoring function measures distances with accelerometer. These two functions show the health data through Line Notify. In addition, we also designed the high secured locking system which has simple usability. Our assessment results reveal high satisfaction from users, high accuracy of data collection and high efficiency of accessories.
