Visualize Cognitive Load with Ease
Cognitive Load Visualizer is a Chrome add-on designed for analyzing the mental demands of web pages. It provides a real-time cognitive-load score ranging from 0 to 100, assessing factors such as visual complexity, interaction density, and layout structure. The tool aims to enhance user experience by identifying areas of a webpage that may cause cognitive overload, thereby helping designers and developers to address potential usability issues effectively.
The extension features a heatmap overlay that visually highlights regions requiring high mental effort, making it easier to spot problematic areas quickly. It operates on the principles of Cognitive Load Theory and offers functionality such as one-click re-analysis for evaluating design changes. Importantly, all data processing occurs locally in the browser, ensuring user privacy by not transmitting or storing any personal information.
