Description
This paper presents the design and simulation of a Fuzzy Logic-based washing machine system tailored for visually impaired users. Visually impaired individuals often face challenges operating conventional washing machines due to the lack of accessible interfaces. To address this, a dual mode Fuzzy Logic control system was developed and simulated, offering both automatic and custom washing options. The system integrates two Fuzzy Logic controllers for enhanced flexibility and control. Simulation and system logic were implemented using MATLAB’s Fuzzy Logic Toolbox for modeling and Python for programmatic control. Key accessibility features include comprehensive audio feedback, flashing indicator buttons, tactile markings, and a simple, high-contrast physical layout. The system adheres to the guidelines set by the Research Institute for Disabled Customers (RIDC), aiming to make automated laundry services inclusive. Preliminary simulations indicate effective customization of water intake, detergent use, spin speed, and drying time based on user or sensor input, suggesting high usability for visually impaired users.
