Abstract
Examples provide a system for automatically identifying a user with a visual impairment and providing assistance navigating a website. A visual assist (VA) manager monitors user interactions with a webpage, such as zooming-in to increase the size of text and graphics and navigation errors, such as clicking on an area outside a clickable icon, failing to enter text in the correct field, etc. A trained machine learning model analyzes the user interaction data using visual assist criteria to predict whether the user has a visual impairment. If the VA manager predicts a visual impairment, an audible VA activation prompt is provided to the user. If the user activates the VA manager, a chatbot is provided to assist the user in performing tasks while navigating the webpage. The VA manager optionally applies user-specific VA settings adjusting the webpage layout and appearance to accommodate the user's visual impairment.
