ABSTRACT
This research proposes the design of a portable electronic dispenser for personal hygiene, which will help reduce the spread of COVID-19, or other diseases or infections that can appear due to lack of hygiene. This dispenser will contain alcohol, will be attachable to the desired arm, either left or right, and will also have a drying mechanism. The disinfectant dispenser and air dispenser will be voice controlled by means of a microphone;the words “alcohol” or “air” must be spoken. When the word “alcohol” is said, the dispenser will begin to expel this liquid toward the direction that is being pointed, be it our hands, body, surroundings, etc. When the word “air” is said, the drying mechanism will be activated, and the air that will start to be expelled will go in the direction that is being pointed, be it to our hands, body, environment, etc. Fourier transform algorithms were used to perform the signal processing. In this work, the MATLAB software was used for the voice recognition of this portable electronic dispenser for the toilet. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
