Perceptual User Experience Lab

About Us: At the Perceptual User Experience Lab, we're interested in how cognitive psychology and user experience (UX) research come together. We aim to uncover insights into the ways people interact with their surroundings, particularly in the realm of technology, innovative designs, and product usage. 

Projects:

  • Video Game Cognitive Tuning is a cutting-edge project focused on enhancing player experiences by identifying and addressing cognitive challenges in video games. Unlike traditional tuning, which adjusts graphical settings or technical performance in the game's code, our approach zeroes in on cognitive issues that arise when players face excessive demands on attention, working memory, or information processing. Utilizing principles from cognitive psychology and human-computer interaction, we analyze instances of cognitive overload to help developers refine game design, ensuring it aligns with players' cognitive capacities and mental models. Our goal is to eliminate unintended cognitive friction, making gameplay more intuitive, accessible, and engaging through thoughtful, user-centered design.​

  • Intuitive Interaction: Harnessing Psychophysical Principles in Digital Design - Aimed at enhancing human-computer interaction, this project explores the application of psychophysics to create digital interfaces that align seamlessly with human sensory and perceptual capabilities.
