Intelligent Virtual Assistant for Elevators Powered by Facial Recognition and Voice Commands

Intelligent assistants are currently categorized as computer programs combined with Artificial Intelligence that interact with the user by voice, messages or images. Thanks to technological advances, intelligent assistants have become widely used in home automation, aiming to automate security, welfare and comfort. This project aims to provide automation for elevators improving the user experience with better security, offering information and user comfort. For this purpose, the application integrates technological tools of facial recognition as part of security and voice activation to command the actuators. Furthermore, the development of the application is oriented to help the multiple users of elevators, especially the group of users with some physical or visual impairment, since it allows the users to mention the floor to which they are going and additionally get a brief overview of what is on that floor, reducing mobility within the elevator, and the search for buttons for the operation of the elevator. The research focused on bibliographic studies on the development of virtual assistants, facial recognition and voice command using free software tools such as Python with its wide range of libraries, and hardware such as PCs, Arduino or Raspberry, depending on the resources needed for the App developed. In the end, a series of tests and satisfactory results with the intelligent virtual assistant are presented to reach the objectives of this study.
