Abstract:
Due to the commodity of the use of the off-the-shelf mobile devices and technological devices by ageing people, the automatic recognition of the Activities of Daily Living (ADL) and their environments using these devices is a research topic were studied in the last years, but this project consists in the creation of an automatic method that recognizes a defined dataset of ADL using a large set of sensors available in these devices, such as the accelerometer, the gyroscope, the magnetometer, the microphone and the Global Positioning System (GPS) receiver. The fusion of the data acquired from the selected sensors allows the recognition of an increasing number of ADL and environments, where the ADL are mainly recognized with motion, magnetic and location sensors, but the environments are mainly recognized with acoustic sensors. During this project, several methods have been researched in the literature, implementing three types of neural networks, these are Multilayer Perceptron (MLP) w
ith Backpropagation, Feedforward neural network (FNN) with Backpropagation and Deep Neural Networks (DNN), verifying that the neural networks that report highest results are the DNN method for the recognition of ADL and standing activities, and the FNN method for the recognition of environments.
