ABSTRACT
COVID-19 has now spread to every continent around the world. The virus is spread through the transmission of close contact with the infected person as well as by touching a surface that has been contaminated with the virus. Touchless switches must be utilized especially in office and home environments to reduce the spread of COVID-19. This paper presents the Smart Interactive Virtual Assistant for Smart Office Door Application. The proposed system uses voice recognition and artificial intelligence by applying the open-sourced API of Google Assistant to control the smart door contactless. The user can give the command to the system via voice to either open or close the door. This smart interactive voice assistant system uses Raspberry Pi as the brain or computer for the interface and Python is used as the software for running the coding script. The components used such as LED lights and DC motors are connected through the General-Purpose Input Output of Raspberry Pi and the relay module. One of the DC motors is used for controlling the lock and another one is used for controlling the door. Blue LED is used as a locked door notification while a green LED is used as an unlocked notification. A pair of microphones and speakers are also connected with the Raspberry Pi as input and output voice commands through a USB port and Bluetooth. With the smart interactive virtual assistant solution, office spaces will move towards a more touch-free control which could prevent the spread of COVID-19.
