65 umagazine issue 18 the armband’s gesture prediction function, the research team studied the autoregressive method by the Akaike information criterion, Wavelet method in intensity analysis, and the Hilbert-Huang transform method. The team also extracted significant factors from surface electroMyography of muscles and used them to predict gestures, with the help of various machine learning techniques, including Genetic Algorithms – Back Propagation Neural Network method, Particle Swarm Optimisation – Back Propagation Neural Network method, Support Vector Machine method, and Extreme Learning Machine method. This allows the Myo armband to be used by the disadvantaged and the elderly in Macao. Intelligent Wheelchair Control System This Intelligent Electric Wheelchair has been designed with ergonomic concepts and AI algorithms to provide different innovative functions. The chair can collect data from the user’s body, such as pressure mapping data of various seating postures and EMG signal. The data can help to improve the design of buildings and facilities which the SAR government or public departments may construct in the future. For example, public facilities, such as bus stops or parks, can be enhanced with the help of this scientific data, which will ultimately improve the quality of life of the disadvantaged and the elderly by using smart city technology. Wheelchairs can easily create pressure ulcers in elderly users because they demand long periods of sitting time. In order to solve this problem, based on the pressure data of human body surface, in the future our team will use machine learning algorithms and neural network algorithms to derive a mathematical model for the prediction of pressure ulcers. Based on this model, our research team will develop an intelligent wheelchair nonlinear control system. Our ultimate goal is to create an intelligent wheelchair control system that uses deep learning algorithms to prevent pressure ulcers. 智能輪椅有助改善殘障人士的出行和生活 The smart wheelchair aims to provide convenience for disabled people in their everyday life 學生向社會各界介紹輪椅的設計概念 Students explain the design concepts of the wheelchair 「學院專欄」內容僅代表作者個人意見 The views expressed in Faculty Column are solely those of the authors, and do not necessarily reflect the views of umagazine or UM.
